    HRV-derived data similarity and distribution index based on ensemble neural network for measuring depth of anaesthesia | killexams.com true questions and Pass4sure dumps

    Introduction

    Anaesthesia is a significantly considerable procedure used in almost whole surgery (Lan et al., 2012; Schwartz et al., 2010). universal anaesthesia is a drug-induced and reversible condition that has specific behavioural and physiological effects such as unconsciousness, analgesia, and akinesia. Clinically and practically, routine observations such as those of heart rate, respiration, blood pressure, lacrimation, and sweating are used to assist doctors in smoothly controlling and safely managing anaesthesia. Nevertheless, patients recovering from universal anaesthesia can sustain significant clinical challenges, including airway and oxygenation problems, emergence delirium (Lepouse et al., 2006), cognitive dysfunction (Saczynski et al., 2012), and delayed emergence, and the aged are particularly at risk of stroke and heart storm (Neumar et al., 2008). Accurate monitoring of the depth of anaesthesia (DoA) would thus contribute to improvements in the safety and attribute of anaesthesia utilize and would provide a superior sustain for patients.

    A status of universal anaesthesia is produced by anaesthetics that act on the spinal cord and the flow and cortex of the brain (Brown, Purdon & Van Dort, 2011; Ching & Brown, 2014); monitoring of electroencephalogram (EEG) patterns is therefore useful (Niedermeyer & Da Silva, 2005). The two main indices derived from an EEG pattern are the bispectral index (BIS) (Aspect Medical Systems, Newton, MA, USA) (Rosow & Manberg, 2001) and entropy (GE Healthcare, Helsinki, Finland) (Viertiö-Oja et al., 2004); the former is obtained by calculating adjustable weights on the power spectrum, the burst suppression pattern, and the bispectrum of EEG data, whereas the latter is constructed by associating the data degree of disorder (entropy) with the consciousness status of patients (Liang et al., 2015; Viertiö-Oja et al., 2004). Although EEG-based spectral indices contain been applied commercially for nearly 20 years, they are still not portion of yardstick anaesthesiology drill (Purdon et al., 2015), and the reasons for this are complex. First, these indices were developed from adult patient cohorts, and are not strictly pertinent to infants or younger patients, thereby providing lower accuracy (Samarkandi, 2006), and second, the indices cannot generate precise DoA measurements for sure drugs, especially when ketamine and nitrous dioxide are used (Avidan et al., 2008; Sleigh & Barnard, 2004). In addition, EEG signals are sensitive to noise, and therefore more complicated algorithms and resources for hullabaloo filtering are required. Moreover, using disposable EEG electrodes is much more expensive than using other physiological signal sensors.

    To overcome some of these disadvantages and provide alternatives to EEG-based solutions (Ahmed et al., 2011), it is crucial to pursue original ideas to support mainstream methods. In this respect, the electrocardiogram (ECG) provides considerable clinical physiological signals and is highly recommended for continuous monitoring and ensuring international standards for the safe drill of anaesthesia (Merry et al., 2010). Different anaesthetics touch the QT interval of an ECG during anaesthetic induction (Oji et al., 2012), and rhythmic-to-non-rhythmic observations from the ECG can provide anaesthetic information (Lin , 2015). In addition, heart rate variability (HRV), related to autonomic regulation, is strongly affected by universal anaesthesia (Hsu et al., 2012) and varies with respect to differing anaesthetic procedures used (Billman, 2013; Mazzeo et al., 2011); therefore, heartbeat dynamics are highly correlated with a loss of consciousness (Citi et al., 2012). Furthermore, ECG signals are more stable than EEG signals, which means that ECG is more resistant to hullabaloo even when cheap electrode sensors are used. HRV analysis thus can subsist used to assess DoA. Moreover, interindividual variation is unvarying and is influenced by age, weight, and life habits, which means that the ECG-derived index more specifically reflects an individual’s anaesthetic status than EEG-based indices that assume one index value indicates the selfsame consciousness flush for whole anaesthetics and patients (Purdon et al., 2015). Performing DoA research based on the HRV is thus valuable. However, it is considerable to guarantee that the ECG is free of artefacts and the ECG waveform (Q R S T waveform) is accurately recognised; otherwise, incorrect variation properties may ultimately subsist obtained, resulting in an incorrect R–R interval distribution.

    An simulated neural network (ANN) is an advanced modelling appliance used in statistics, machine learning, and cognitive science (Alpaydin, 2014; Kriegeskorte, 2015). This bio-inspired way supports self-learning from complicated data by organizing training pattern set and resultant errors between the preferred output and the subsequent network output. It has the majestic competence of non-linear, distributed, local, and parallel processing and adaptation and one of the most often used models in engineering applications. An ensemble simulated neural network (EANN) comprises multiple models and combines them to produce the desired output, as opposed to using a solitary model (Kourentzes, Barrow & Crone, 2014; Ripley & Ripley, 2001; Tay et al., 2013). Normally, an ensemble of models performs better than any individual model because mediocre effects are obtained in ensemble models (Baraldi et al., 2013; Zhou, Wu & Tang, 2002). In summary, the neural network is a powerful and efficacious way for utilize in data regression and model optimisation of nonstationary data. In biomedical fields, neural networks play a crucial role in the analysis of complicated physiological data (Amato et al., 2013).

    This study aimed to optimise an indicator index, known as the similarity and distribution index (SDI), that is derived from measurements of HRV (Huang et al., 2008). The SDI is proposed to evaluate the DoA from ECG signals occurring in the time domain during routine surgery, and thus differs from the methods previously described herein, which are based on extracting EEG spectrum features in the frequency domain. The time domain parameter is calculated by measuring the similarity between the statistical distributions of R–R interval measurements in consecutive data segments. In this study, results obtained using the proposed way are compared with the expert assessment of consciousness flush (EACL), which is determined using the mediocre evaluation of five expert anaesthetists after data and patient observation. The model is then optimised by applying an EANN for estimating the DoA. Through SDI extraction in the time domain and EANN modelling targeting the EACL, results note that it is feasible to predict the DoA throughout an entire surgery.

    The remainder of this paper is divided into four sections. ‘Materials and Methods’ describes the universal anaesthesia used, patient participants and data analysis methods employed; ‘Results’ presents the results of processing and comparisons with the EACL; ‘Discussion’ presents the discussion and study limitations; and the conclusion is provided in ‘Conclusions’.

    Materials and Methods Ethics statement

    All studies were approved by the Research Ethics Committee, National Taiwan University Hospital (NTUH), Taiwan, and written informed consent was obtained from patients (No: 201302078RINC). During the experimental trial, the hospital endeavoured to ensure that whole scheduled surgery was performed very well on time.

    Standard anaesthetic procedure

    Anaesthesia is essential during surgery, and its associated procedures are outlined in Fig. 1 (Cornelissen et al., 2015). Anaesthesia generally involves end-tidal gas concentration over time, and routine anaesthetic drill consists of four stages: consciousness, induction, maintenance, and emergence (recovery) (Merry et al., 2010). Prior to surgery, patients were required to occupy nil by mouth for at least 8 h. After the electrodes were placed, each patient received the volume of anaesthetic agents appropriate for the routine operation. Unconsciousness is usually induced by intravenous propofol, another analgesic drug (such as fentanyl), and a muscle relaxant medicine (such as nimbex). Gas anaesthetics (desflurane, sevoflurane) together with air and oxygen were used to maintain sedation for most patients after the mask had been placed, whereas propofol was employed in some cases. As the close of surgery approached, additional drugs were administrated (such as morphine and atropine). Table 1 summarises circumstantial information. universal anaesthesia was performed safely during whole stages by monitoring physiological signals, such as EEG, ECG, photoplethysmography (PPG), and intermittent vital signs of blood pressure (BP), heart rate (HR), pulse rate (PR), and pulse oximeter oxygen saturation (SpO2). If any of these observation signals underwent irregular changes, the anaesthetist adjusted the intraoperative yardstick anaesthesia machine correspondingly.

    ECG data acquired in this study were obtained from patients undergoing surgery at the NTUH using chest-mounted sensors and a MP60 anaesthetic monitor machine (Intellivue; Philips, Foster City, CA, USA). The machine was connected to a recording computer installed with real-time software developed by their research team using a Borland C+ + Builder 6 developing environment kit (Borland Company, C+ + version 6); this software collected data at a sampling rate of 500 Hz. The sampling rates of the EEG and PPG continuous waveforms were 128 Hz. Intermittent vital signs (such as BIS, HR, PR, BP and SPO2) were recorded every 5 s.

    Figure 2: Study protocol. In fact, patients before this collection age were consulted for their eligibility, dozens of cases were excluded for analysis such as technical and clinical reasons. The 110 remaining subjects are intact for four stages of analysis to evaluate depth of anaesthesia (DoA). Their demography information is shown in Table 1. Clinical data collection

    Prior to collecting data in this study, patients provided written consent for participation. Demographic and clinical data, including height, weight, age, gender, operation time, surgical procedure, and anaesthetic management, were acquired by hospital staff from anaesthesia recording sheets. Other data relating to the research procedure, such as carcass movement and electrotome operation, were recorded by the research team. Regular hospital recordings and specific research notes were then integrated to serve as auxiliary clinical information.

    Patient participants

    Patients scheduled for elective surgical procedures were recruited from the preoperative clinic at NTUH in 2015. Eligibility criteria related to age, consent, and specific operation type. Those ineligible for inclusion were either (1) under 22 years old, (2) diagnosed with a neurological or cardiovascular disorder, or (3) undergoing surgery involving local anaesthetic rather than general. The selection procedure is illustrated in Fig. 2. According to these criteria, hundreds of patients were eligible for inclusion. However, it was unfortunately not feasible to obtain data for whole eligible patients (technique failure, procedure interruption), and ultimately data for 110 patients were acquired. universal parameter information was obtained for whole 110 patients. However, anaesthetic drug management differed with respect to individuals, although propofol and fentanyl inductions were implemented for most patients (n = 100). The circumstantial characteristics of the participants are provided in Table 1.

    ECG data preprocessing Data conditioning

    Data conditioning, or preprocessing, is faultfinding for signal analysis for determining DoA and can overcome problems with compatibility and a lack of analysis in advance. It generally consists of data format conversion, hullabaloo removal, and data rearrangement. Due to limitations with data collection storage, an ASCII file format was used in this study. Prior to implementing the algorithm, data were transferred into a MATLAB workspace and the notch filter was then used to remove 60 Hz power line noise. whole participant data sets were then manually inspected to determine specific segments of artefacts resulting in extremely abnormal QRS waveforms or ECG progression saturation (for example, electrical artefacts caused by medical tackle or carcass movement), particularly for the R peak, which was previously impossible to recognise. Their algorithm was then applied to pre-processed data for further analysis.

    EACL

    It is common erudition that no accurate yardstick index exists that is capable of symbolising a patient’s anaesthetic status during clinical surgery. Therefore, five experienced anaesthesiologists were asked to plot subjective scores relating to ‘state of anaesthetic depth’ versus time, based on the data recordings referred to in the previous section and their own flush clinical experience. These scores thus represented an EACL. Criteria determined by the five anaesthesiologists with respect to their assessments of consciousness flush were based on both their clinical drill erudition and supporting information recorded by two research nurses. Any clinical events and signs potentially related to DoA were carefully recorded. Recorded information included (i) intermittent vital signs (such as HR, BP, SPO2); (ii) anaesthetic events, including induction of anaesthesia, tracheal intubation and extubation, the addition of muscle relaxant reversal drugs, and managing airway suction; (iii) surgical events, including the start and close of surgical procedure and the circumstance of any specific noxious stimulus; (iv) clinical signs of the patient, including any types of movement and unusual responses and arousability during induction and emergence from anaesthesia; and (v) any other events that were considered relevant, such as patient demography.

    Figure 3: Flowchart design of expert assessment of consciousness flush (EACL). Recordings are clinically related BP, HR, SPO2 and drug administration records; assessments are done by five experienced experts by plotting the DoA curves with ambit from 0 to 100. After using ANSYS to digitalize the curve value, they obtained the final gold yardstick by averaging the five doctors’ assessments. EACL: expert of assessment of consciousness level.

The Red solid line is the value value, the two green dashed line is value ± std. Figure 5: Similarity and distribution index (SDI) definition protocol. ECG denotes step 1, R (n) means step 2. Step 3 includes D (n) and histogram. The histogram distribution is used for SDI computation.

    Based on these criteria (Liu et al., 2015), the assessment procedure used in this study to score DoA (Fig. 3) is described as follows. First, research nurses continually observed each patient’s status to record the information described above. Each anaesthesiologist then made a continuous assessment and celebrated changes in ‘the status of anaesthetic depth’ of patients during the entire operation, based on hospital formal anaesthesia records. To maintain consistency with the BIS, scoring used the ambit of 0–100, from brain extinct to fully awake (a score of 40–65 represents an appropriate flush of anaesthesia during surgery). Finally, because original assessments were drawn by hand, the results were digitised using web-based software (webplotdigitizer; ANSYS, Canonsburg, PA, USA) (Dorogovtsev & Mendes, 2013) and resampled every 5 s using MATLAB interpolation to ensure concurrence with the BIS index. The result was then considered to subsist an EACL. However, because the sustain of each anaesthesiologist differed with respect to subjective EACL standards, and to minimise the consciousness flush oversight as much as possible, the data obtained from the five anaesthesiologists were averaged. design 4 shows one EACL case example from the five doctors and the value value of the five scores, where it is evident that the value value better represents absolute DoA.

    Data analysis SDI definition of HRV SDI protocol.

    The SDI is based on HRV recorded in ECG data. The SDI is a time domain parameter index representing the degree of similarity between consecutive data segments and is obtained by computing the statistical distribution of the R–R interval variability difference. design 5 shows details of the entire procedure used to compute the SDI from ECG recordings. The steps involved are as follows:

    Step 1. Extract the R peak of the ECG signal to obtain the instantaneous R–R interval, R n . Resample the data using the commonly used algorithm of Berger to 4 Hz (Berger et al., 1986).

    Step 2. reckon the incompatibility between two consecutive heartbeat intervals: (1) D n = R n + 1 − R n n = 1 , 2 , 3 …

    Step 3. select any time point, t, and then select a data block, where the data obstruct contains M data points. Compare the statistical distribution of consecutive blocks, one from D(t − M + 1) to D(t), the other from D(t + 1) to D(t + M). Distribution histograms of both data blocks are generated using the selfsame cell size. The relative frequency of the D n value of the ith cell of the histogram is denoted P1(i) for the first data obstruct and P2(i) for the second. Determination of the cell number is described in ‘Data analysis’ portion B below. For example, in the first data block, the data value ambit is 0 to 0.5 s if 100 cells are chosen, and the cell width should subsist set as 0.005 s. This means that P1(1) denotes the relative frequency between 0 and 0.005; that is, P 1 1 = relative frequency 0 < D n < 0 . 005 , P 1 2 = relative frequency 0 . 005 < D n < 0 . 010 and so on. This is the selfsame for the second data block.

    Step 4. After multiplying the relative frequency of corresponding cells in the histograms of both data blocks, the sum of the product value in whole cells is the SDI, as calculated using the following equation: (2) SDI = 1 − ∑ i = 1 n P 1 i ∗ P 2 i × 100 , where n is the number of cells and P1(i), P2(i) are the relative frequencies of each cell in the histograms of data blocks 1 and 2, respectively. Theoretically, towering similarity between the distribution features of ECG data means that patients are in a stable physical condition during surgery and that they are under a status of anaesthesia with towering values of P1 × P2. When the sum is deducted by 1 and shows a lower SDI, the DoA is deeper. When the sum is multiplied by 100, the index value ranges from 0 to 100 and is consistent with clinically recognised consciousness levels, such as BIS values that ambit from 0 (deep coma) to 100 (awake state), thus making it easier to determine the DoA.

    Implication of SDI value.

    Mathematically, the SDI is obtained from measuring features of the statistical distribution between two consecutive data segments. For a stable HR pattern, the consecutive data segments should contain towering similarity and a histogram will note a consistent distribution when P 1 i and P 2 i fluctuate simultaneously. Under the condition of Eq. (2), the SDI is lower in this situation; therefore, a higher SDI symbolises a much more variable HR, which occurs frequently when a patient is awake or under minimal anaesthesia. In this instance, the SDI can subsist expressed in accordance with the BIS index.

(A) shows one SDI curve derived from a case ECG data, (B) one is the corresponding EACL, in which the blue thick line is the mediocre of other five doctors’ thin lines. Figure 8: Histogram distribution of correlation coefficient between SDI and EACL. Except one in negative correlation, others are positive values, of which most are located at towering value section from 0.6 to 0.9. Table 2:

    The latter one has better performance except few cases. From p value (paired Student t test), the two groups are considered statistically significant. (P < 0.05 means statistically significant).

    Data from the 110 participants were analysed to obtain the SDI. For every case, the SDI was calculated using data from the entire operation procedure, including the awake, induction, maintenance, and recovery states. whole data were obtained under different types of anaesthetics to guarantee compatibility, and parameters were selected empirically. Because D n was in the ambit of 0 ms to 0.5 ms, it was used as the length of the histogram. The number of cells used was 100–500, and the best performance was obtained for 250. Dividing the data ambit into 250 cells required a cell width of 0.002, and the data block, M, was set as 128. Sample frequency D n of 4 Hz was used, and thus one data obstruct required 32 s. At any one time, 64 s of data (two 32 s data blocks) were required to reckon the SDI.

    ANN analysis

    The Pearson correlation coefficient was calculated for 110 intact cases. To measure the DoA accurately, regression analysis was conducted to compute the model. ANN analysis was utilised to determine the relationship between the SDI and EACL, thereby generating a more accurate output for evaluation. An ANN consists of three parts: an input layer, a hidden layer, and an output layer. In this study, a feedback propagation–type ANN was used, which is the most widely used character of ANN in machine learning. In previous studies (Huang et al., 2013; Liu et al., 2015; Sadrawi et al., 2015), nonlinear and nonstationary medical data were used with a back propagation network that had four layers: an input layer, two hidden layers with 17 and 10 neuron nodes, respectively, and an output layer. The number of nodes and layers used is widely known to touch the performance of an ANN, including the fitting result and time elapse. From an engineering perspective, three to four layers are mostly used (Kourentzes, Barrow & Crone, 2014; Ripley & Ripley, 2001). In this study, different ANN topologies were tested, where the performance of the network varied as a function of the data type. A final topology was selected that obtained the highest accuracy in the shortest time.

    Because the SDI data progression is being used as the input to obtain a result similar to the EACL, the SDI needed to subsist consistent with the EACL for each case. As previously mentioned, there were variations in the subjective opinions of the five anaesthetists who completed the EACL, which thus resulted in a low correlation coefficient due to the different assessments. Therefore, 105 out of 110 data sets that had correlation coefficients higher than 0.3 (most of the value distribution was much higher than 0.3, as shown in the following ‘Statistical distribution of the correlation coefficient’ were used for ANN regression. In addition, 85 data sets were used separately in the model’s construction: 70% were used for training, 15% for validation, and 15% for testing. To enable selection of the best neural network, 1,000 epochs were set, and a large volume of data was employed to guarantee that the ANN model had a favourable fit. After the ANN model was generated, 20 sets of data were used for pure-testing of the ANN model to validate its performance.

    The modelling procedure was repeated 10 times to generate 10 ANN models for cross-validation, and the procedure involved was as follows. The initial weights were set randomly, and as mentioned previously, the training was set to 1,000 epochs. The data were finally used to create 20 models for testing of model accuracy. The data were acquired from regular surgical procedures conducted in the NTUH using convincing and strict operating procedures and identical regimes. Each model was totally different, due to the randomness of the initial weights. The performance for the cross-validation of 10 models was then calculated to check the variability of the ANN models. The results showed that a different model was created each time ANN training was performed, despite using the selfsame data set for the training, validation, and testing. Cross-validation was conducted in a blind test to prove that there was no change in the regression result despite changes in the samples input.

    In addition, an EANN was employed to optimise the prediction results. Utilisation of an ensemble obtains higher accuracy than using other neural network approaches (Minku & Yao, 2012) and can address the trade-off between prediction diversity and accuracy within an evolutionary multiobjective framework (Chandra & Yao, 2004). As shown in Fig. 6, a solitary network model can subsist established with the random creation of initial weights, scales, and parameters. In this study, 85 data cases were used to generate 10 ANN models with different initial weights, and the 10 ANN outputs were then averaged to validate the 20 cases for optimising the regression effect. Because each ANN generates a different result with a different error, the mediocre of the model outputs was calculated to overcome associated errors, thus creating an EANN to better results. whole data analyses were conducted with MATLAB (Mathworks, R2014b, US).

    Statistical analysis was performed using SPSS (IBM v22, North Castle, NY, USA) and MATLAB. To evaluate the ANN effect, the performance of the original SDI was compared with the one random ANN regression–derived SDI. The Pearson correlation coefficient, value absolute oversight (MAE), and zone under the curve (AUC) for the EACL were computed and considered the gold standard. The receiver operating characteristic (ROC) curve was calculated to obtain the AUC, which is often used in medical fields during diagnosis of disease. The binary threshold used to distinguish between anaesthesia and consciousness was set to 65 (Johansen & Sebel, 2000). The parametric paired Student’s t-test was then used to assess the statistical significance. To prove the capability of the EANN-derived SDI to measure DoA, its relationship with EACL was analysed. Furthermore, the commonly used BIS was used as a reference. The selfsame significance test was likewise undertaken between the two indices, thus demonstrating a solid and convincing result.

    Results Demonstration of typical SDI pattern

    Figure 7A shows a typical SDI trend for a representative patient, and Fig. 7B displays the corresponding EACL obtained from the scores of five experienced and professional anaesthesiologists. The DoA is shown to change throughout the operation, where a higher value denotes a lower flush of consciousness. After induction, the SDI falls sharply, although some variation exists in the maintenance period, and the SDI increases dramatically during emergence from anaesthesia. Generally, it corresponds with the fluctuations of EACL.

    Statistical distribution of the correlation coefficient

    To determine the coefficient distribution characteristics of whole 110 data sets, a histogram with a cell width of 0.1 was constructed (Fig. 8). Most of the data values are located in the ambit from 0.6 to 0.8, with value ± SD equal to 0.78 ± 0.16, which reflects a stout relationship with the EACL. Only five cases note extremely low correlation, these cases were just discarded.

    Comparison between performance of original SDI and SDI proper using an ANN

    An ANN model can subsist trained to model nonlinear behaviour and was used to accurately evaluate DoA in this study. Twenty data sets were used to quantify the optimisation effect, and a comparison was then made to validate the ANN effect. The correlation coefficients between the EACL and both the original SDI and ANN-derived SDI for cases 1 to 20 are presented in Table 2. It is evident that the ANN-derived SDI has significantly improved correlation with the EACL compared with the original SDI (p < 0.05). From the value value of the statistics shown in Fig. 9A, it is clear that the ANN-derived SDI has superior performance. Table 3 compares the MAE results in the shape of correlation coefficients. The MAE fitting results obtained for the ANN-derived values are much smaller than those obtained without the ANN, which demonstrates that the ANN performed favourably. It decreases the incompatibility much from the EACL by showing the statistical results in Fig. 9B significantly (p < 0.05). In addition, the AUCs of both the original SDI and the ANN-derived SDI for the 20 cases were calculated, and the results are shown in Table 4. Furthermore, the ROC curve for one case is presented in Fig. 10 and proves that the optimised SDI evaluates the flush of consciousness more accurately. design 9C shows that the AUC of the ANN-derived SDI is 0.95 ± 0.05, much higher than that of the original SDI. The paired Student t-test was then used to determine the incompatibility flush between the two groups. The comparison reveals a statistically significant incompatibility (p < 0.05), indicating the favourable fitting result for the SDI using the ANN. From the relationship and the value difference, it is evident that the ANN-derived SDI measures the DoA more accurately than the original SDI.

    Figure 10: The receiver operating characteristic (ROC) curve of original SDI and simulated neural network (ANN) derived one. Both note the prediction of DoA features (AUC > 0.5). The ANN fitting SDI (blue curve) has larger AUC than the original SDI (red one), indicating better competence to predict DoA. Figure 11: One typical representative of the ANN regression result for SDI. The blue line represents the ANN derived output; it has more similar fluctuation meter with EACL (black line). Relatively, the original SDI (red line) shows weaker relationship.

    A typical ANN-derived curve is displayed in Fig. 11; the results were derived from the case shown in Fig. 7. Clearly, the ANN-fitted SDI is superior to the original SDI, which varies sharply at the induction stage, whereas the ANN-derived SDI is basically consistent with the EACL. Furthermore, the original SDI reaches zero during the early maintenance period, which is definitely unreasonable.

    ANN blind cross-validation

    The results circumstantial demonstrate that the ANN model improves the SDI performance. However, because only one ANN model test was conducted, a blind cross-validation test was conducted using the previously mentioned 20 cases to ensure that the ANN model was efficient. The results are presented in Table 5 and divulge that whole 10 ANN models used for the 20 cases provide similar results. The selfsame validation test was used for the MAE (Table 5). This demonstrated that the samples selected conclude not touch the construction and effectiveness of the ANN.

    To further better the regression performance of the ANN, an EANN was utilised to predict the DoA. design 12A shows that the ANNs had cramped variance in terms of the correlation coefficient. The EANN has the highest correlation and the lowest yardstick deviation, thereby proving the superior performance of the EANN. In addition, the MAE distribution is shown in Fig. 12B. The individual ANNs had similar characteristics. In addition, the EANN has the lowest MAE, which is consistent with the correlation coefficient results.

    In comparison with the commonly used BIS, Fig. 13 shows that the EANN-derived SDI performs better than the BIS evaluation when referring to the EACL as the gold standard. Differences in terms of the correlation coefficient, MAE, and AUC are whole significant (p < 0.05 parametric paired Student’s t-test). They likewise chose one representative case for which to plot the ROC curve for both the BIS and EANN-derived SDI (Fig. 14), where the AUC illustrates better discrimination between anaesthesia and consciousness. Tables 6 and 7 provide circumstantial results for the EANN and BIS over 20 cases, respectively.

(A) shows that the ANN has cramped fluctuation incompatibility regardless of input training data in terms of correlation coefficient. The EANN has the highest correlation with lowest yardstick aberration to prove the better performance of EANN. MAE distribution is given in (B). As to individual ANN, they contain similar ability, but not significantly. Similar to the result of correlation coefficient, EANN has almost the lowest MAE. Figure 13: incompatibility between the BIS and EANN derived SDI for correlation coefficient, MAE and AUC using EACL as gold standard.

    Doctors utilize many observations and physiological vital signs to evaluate flush of consciousness during clinical operations. The medical parameters are usually HR, BP, and photoplethysmography (Merry et al., 2010). However, because these parameters cannot accurately limn the actual DoA, researchers contain been developing original methods for this purpose. For example, auditory evoked potential (AEP)- and EEG-related indices (which are mentioned in ‘Introduction’) such as BIS or entropy contain been employed to quantify DoA (Liu et al., 2015; Nishiyama, 2013; Rosow & Manberg, 2001), and such indices are powerful and efficacious to some extent. An SDI method, which is based on ECG signals, is proposed in this study to measure DoA. The SDI way has a stout relationship with HRV, which is correlated with autonomic nervous system (ANS) function. Such function is seriously affected by anaesthesia (Hsu et al., 2012; Tarvainen et al., 2010), and because this fact is widely accepted in the province of anaesthesia, the ECG has often been used in DoA research.

    Our aim was to construct a practical ECG-derived index, and thus the SDI proposed in this study is constructed to correspond with the EACL, the gold yardstick that researchers adhere to when developing methods of measuring DoA. EACLs were thus obtained by their research team members, which involved a large amount of pains and endeavour. Although DoA was clinically scored by experienced anaesthesiologists in this study, there were limitations associated with the subjective opinions of each anaesthesiologist, and it was thus necessary to collaboratively score sure cases. The aim of this paper was to pose the utilize of the SDI to measure DoA; thus, the SDI still requires sure future improvement with respect to the mathematical principles used. For example, the SDI is affected by ECG data fluctuations, which are related to the distribution and similarities between data obstruct points. Parameter selection details must likewise subsist further investigated. Moreover, it is necessary to obtain a clearer understanding of the comparisons made between the SDI and the BIS, AEP, or entropy. It is considered that both EEG-derived and ECG-derived indices provide specific and useful features, and therefore further research is required in this respect.

    The ANN regression model used herein was obtained from a predefined framework of an initial neural network based on their previous engineering research sustain (Jiang et al., 2015; Liu et al., 2015; Sadrawi et al., 2015). However, it would subsist beneficial to investigate the ANN’s parameters, such as numbers of layers, number of nodes in each layers, and character of ANN (Hinton et al., 2012), and to argue the weights and expiration criteria for the maximum optimisation of the performance.

    Mathematically, the SDI does not limn heart rate or HRV but quantifies the incompatibility between two consecutive data blocks (as explained in detail in ‘Materials and Methods’). When the incompatibility is higher, the SDI value is likewise higher. The index is presumably affected by the shape of the distributions, as well as their similarity. If P1 and P2 are identical but both note either a uniform distribution (each value equally likely) or are deterministic (only a solitary value occurs in both), for example, different SDI will result. In the latter case, the SDI =1 − 12 = 0, and in the former case, SDI =1 − 100 × (1∕100)2 = 0.99, for n = 100. Therefore, the SDI not only measures similarity but is likewise affected by D(n), which means it can limn ECG data variability. Instead of simply using the correlation coefficient between the ECG and EACL as a definition of the SDI, which would subsist less contingent on shape, they used the procedure outlined in ‘Data analysis’, portion A, to define the final yardstick SDI. Although an ANN has a relatively complicated relationship with DoA, it is utilised for the regression and an output is obtained to quantify DoA, thus solving the nonlinearity between the SDI and DoA. In addition, when patients are conscious, the ANS has a regulation function that affects ECG signals. sure types of heart disease influence HRV (Mazzeo et al., 2011) and probably likewise the SDI. It is thus imperative for us to validate and optimise this potential effect, even though the regression results emerge to subsist favourable. They do, however, assume that the SDI is not currently suitable for utilize in whole occasions, and research is thus required to explore and amend any problems with the algorithm.

    Although data from more than 100 cases were collected to build the SDI and the results demonstrate favourable performance, most of their cases were middle-aged patients. Therefore, it is necessary to obtain more data from youthful patients to verify their methodology (Cornelissen et al., 2015; Gemma et al., 2016), Surgery is conducted with respect to sure protocols and patient safety is always the priority; therefore, the anaesthetic drugs used for the patients in this study were whole chosen by experienced anaesthesiologists, who perhaps favoured the utilize of particular drugs. Although other types of drugs could likewise deliver successful outcomes (Mawhinney et al., 2012; Schwartz et al., 2010), the data obtained during the maintenance age were only related to the administration of propofol, sevoflurane, and desflurane (Table 1). It is thus necessary for us to obtain data based on the utilize of other drugs such as medetomidine, isoflurane, and nitrous oxide (Kenny et al., 2015; Purdon et al., 2015), which may enhance index compatibility. In addition, mixed anaesthetic agents were given to the patients, which made it difficult to evaluate the capability of the SDI to reflect the utilize of one specific drug regime. Furthermore, their data are obtained from routine surgery performed in a hospital and conclude not involve any other clinically specific anaesthetic settings; thus, investigations of this aspect would likewise subsist useful. They will conduct future experiments using related data, and strict and rigorous comparisons will subsist made between indices. Future efforts will subsist made to investigate and update their algorithm and to determine the possibility of improving DoA evaluation accuracy through a combination with BIS or entropy, for example, or consideration of different surgical circumstances.

    Another issue to subsist considered is the spectral analysis of the ANS. ANS function has been widely employed in the assessment of DoA using ECG frequency domain features (Guzzetti et al., 2015; Lin et al., 2014). Previous articles contain mainly focused on the ratio between towering and low frequency powers. Galletly et al. (1994) described the spectral influence of several common anaesthetic agents on HRV, which provides directions for spectral portion analysis. In addition, multitaper time frequency analysis was undertaken for autonomic activity dynamics evaluation in Lin et al. (2014). Nevertheless, future research on spectral analysis is required to pursue the promising and valuable integration with the present temporal analysis. Finally, although the results of this travail symbolise DoA from the perspective of the ANS, they likewise aimed to provide an alternative to EEG-derived evaluation (Purdon et al., 2015; Samarkandi, 2006; Sleigh & Barnard, 2004). Based on the results of this research, it is considered that to overcome the disadvantages of EEG-based methods, studies should subsist initiated using a combination of EEG- and ECG-based methods.

    Conclusions

    In this study, physiological data from 100 participants were analysed to determine the competence of their SDI algorithm to evaluate DoA. ECG data were used to derive the SDI, representing the differences in HRV to demonstrate the competence of the SDI to measure DoA. To optimise prediction accuracy, ANN models were constructed and blind cross-validations were performed to conduct a regression test. In addition, an EANN was employed to overcome random errors and overfitting of the ANN models. This study indicated that HRV analysis has the potential to become another efficacious way for the evaluation of DoA. However, because there is a current lack of example measurement methods for the assessment of patient consciousness level, it is considered that incorporating the SDI into other methods would subsist useful. Therefore, combining the utilize of the SDI with other physiological medical signals relating to anaesthesia, such as EEG signal, would likewise subsist meaningful and helpful in improving the accuracy of DoA evaluation.
