We retrospectively reviewed 307 high-risk spine surgery cases monitored with Tc-MEPs from 2018 to 2020. For waveform-level analysis, 1,748 muscle waveforms from 287 FP/true-negative cases were analyzed. Alerts were defined as final amplitude ≤ 30% of baseline, and FP alerts were defined as alerts without new postoperative motor deficit. Receiver operating characteristic analyses were performed to estimate baseline-amplitude cutoff values for FP alerts in spinal cord tumor surgery, spinal deformity surgery, ossification of the posterior longitudinal ligament surgery, and the pooled cohort. FP alerts occurred in 253 of 1,748 waveforms (14.5%). Baseline Tc-MEP amplitude was lower in FP than in true-negative waveforms (351 ± 533 µV vs. 604 ± 1007 µV). FP alerts were more frequent in lower-extremity recordings. Exploratory ROC-derived cutoff values were 122 µV for spinal cord tumor surgery, 180 µV for spinal deformity surgery, 160 µV for ossification of the posterior longitudinal ligament surgery, and 170 µV for the pooled cohort; the corresponding AUCs were 0.68, 0.56, 0.61, and 0.61, respectively. Lower baseline Tc-MEP amplitudes were associated with FP alerts. Baseline amplitude assessment may help identify low-amplitude signals that warrant optimization and cautious interpretation before percentage-based alarm criteria are applied.","PeriodicalId":15513,"journal":{"name":"Journal of Clinical Monitoring and Computing","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149074930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although modern anesthesia workstations offer real-time spirometry pressure-volume loops for each breath, their clinical utility remains limited. This study aimed to develop a deep learning model using a convolutional neural network to analyze spirometry pressure-volume loops in patients undergoing laparoscopic or robot-assisted surgeries and to design a clinically applicable index using gradient-weighted class activation maps to enhance interpretability. This retrospective study was conducted across two tertiary hospitals, involving data from 207 patients who underwent laparoscopic or robot-assisted abdominal surgeries for model training. Data from 45 patients at an independent hospital were used for external validation. Thus, data from a total of 252 patients were used. The primary outcome measure was the model's ability to predict postoperative desaturation. The performance of the model, along with that of the derived clinical index, was evaluated using the area under the receiver operating characteristic curve (AUROC). The deep learning model predicted postoperative desaturation with AUROC (95% confidence interval) values of 0.825 [0.744-0.905] and 0.688 [0.656-0.720] on internal and external validation datasets, respectively. The desaturation predictive index demonstrated moderate predictive performance on both internal and external datasets (AUROC: 0.774 and 0.722, respectively). These findings support the efficacy of both the deep learning model and the predictive index in forecasting postoperative desaturation, thus highlighting the potential of real-time spirometry in postoperative monitoring research.","PeriodicalId":15513,"journal":{"name":"Journal of Clinical Monitoring and Computing","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149069711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interpretation of nociception monitoring during cardiac surgery involving cardiopulmonary bypass (CPB), however, is complicated by profound physiological alterations including non-pulsatile circulation, cardioplegic arrest, temperature modulation, vasoactive and inotropic support, pacing, haemodilution, and systemic inflammatory responses. Current monitoring technologies rely on surrogate autonomic, vascular, pupillary, and electroencephalography-derived signals, many of which become difficult to interpret during CPB. Although several modalities demonstrate responsiveness to surgical stimulation under relatively stable perioperative conditions, cardiac-specific validation remains limited and extrapolation of available evidence into CPB conditions remains uncertain.

Extended near‑infrared spectroscopy (eNIRS) can enable real-time intramyocardial monitoring of hemoglobin/myoglobin oxygen saturation (SHb/Mb) and cytochrome c oxidase oxidation (OCcO) for assessment of cardiac oxygen availability and utilization during surgery. In this prospective, single-center feasibility study, myocardial eNIRS monitoring was carried out in 15 adults undergoing aortic valve replacement with or without coronary artery bypass grafting. The study focused on initial feasibility and performance. Clinical performance was explored by relating changes in OCcO responses to intermittently administered blood cardioplegia volumes. Myocardial eNIRS consistently recorded SHb/Mb, and OCcO responses to cross-clamp, cardioplegia, and reperfusion throughout all operations. Mitochondrial oxygenation status improvement (OCcO area under the curve) correlated with the intermittently administered volume of blood cardioplegia (r = 0.68, p < 0.0001). No device-related adverse events were observed. Feedback on usability was favorable (surgeons 87%; anesthesiologists 85%; nurses 74%). Intraoperative myocardial eNIRS monitoring is feasible. It provides continuous assessment of oxygen availability and mitochondrial redox status during surgery.

Furthermore, we investigated the sedative effects of remifentanil and the effect of propofol-induced loss of responsiveness (PI-LOR) on CHEPs. After determination of the individual pain threshold (visual analog scale (VAS) of 10), 120 adult ASA physical status I or II patients randomly received remifentanil in one of four predefined infusion rates (0.05, 0.1, 0.2, or 0.4 [Formula: see text]g/kg/min). After equilibration, a heat stimulus 20% above the individual pain threshold was applied to the volar forearm. Eventually, propofol was infused until LOR, and the heat stimulus was applied again. CHEPs, VAS, and the Observer's Assessment of Alertness/Sedation (OAA/S) scale, as well as middle latency auditory evoked potentials (MLAEPs), were assessed. A total of 119 patients were included in the analysis. CHEP amplitudes could not be detected for all patients at all times. Remifentanil dosage and VAS showed a strong inverse correlation (r=-0.46; p<0.001).

Data were partitioned into training, validation, and test sets; class imbalance was addressed with SMOTENC on the training data alone. Seven algorithms: logistic regression, decision tree, random forest, XGBoost, LightGBM, histogram-based gradient boosting, and explainable boosting machine (EBM) were compared using discrimination, precision-recall, and calibration metrics at two operating points (fixed sensitivity and fixed specificity). Unplanned admission occurred in 9.08% of patients. Discrimination varied markedly, the highest area under the receiver operating characteristic curve achieved by the explainable boosting machine (EBM, 0.826), the lowest by logistic regression (0.595). Given the rarity of the outcome, precision-recall was most informative: the EBM attained both the highest average precision (0.472) and F1-score (0.392), exceeding the black-box ensembles while remaining intrinsically interpretable. Performance was stable between validation and test sets, arguing against overfitting, although all models over-estimated risk and need recalibration. Machine learning applied to routinely collected data can identify patients at risk of deviating from their intended day-case pathway with stable performance and the potential for clinical usefulness. The explainable boosting machine is especially attractive, combining competitive accuracy with transparency. Prospective validation and recalibration of the predicted probabilities will be required before clinical deployment.","PeriodicalId":15513,"journal":{"name":"Journal of Clinical Monitoring and Computing","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148911390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This data almost always contains artifacts caused by clinical staff attending to the patient throughout the day, e.g. blood samples being taken, body washing, administration of IV medication. We present a small (10 patient) study but with accurately annotated clinical event data constructed by observing standard clinical procedures and merging this information with the physiologic data (ECG, ABP, CVP) from bedside monitors. In addition, to assess the feasibility for using accelerometers in the ICU environment, we received ethical approval to place an accelerometer [1] on the chest of all patients and the X, Y & Z accelerometer plane data was merged with the physiological and event annotation data. The non-trivial methods required to capture the data and initial characterisation of results are detailed and discussed. A baseline model cross-correlating ECG and ABP waveform signals over a 10 s window was developed and features derived from this model were used in both GLM and Random Forest (RF) models for predicting events that routinely cause movement related artifact in waveform quality time-series data. RF model performance improved when accelerometer data was added to the model for most movement related artifact types. For the GLM models, only selected models (ANY Type, Turns, Bed Movement and Blood Sample) showed an improvement in model fit with the addition of the accelerometer data (P < 0.01).
