“…Controversy exists on the use of these measures to monitor loss and return of consciousness, depth of anaesthesia and hypnotic drug effect. Initial reports on the classical univariate EEG measures (MF and SEF 95% and RDEL-TA) concluded that these correlated well with anaesthetic adequacy (27)(28)(29). All these investigators used haemodynamic or somatic (movement) response to surgical stimulus as the clinical end-point to assess the accuracy of the different anaesthetic depth indicators (3), but this clinical end-point has proved not to be accurate for this purpose (19).…”

“…Fourth, other data obtained from the PAC, such as cardiac output and mixed venous oxyhemoglobin saturation, were not analyzed because they were not recorded as continuous electronic data. Sixth, the depth of anesthesia [ 37 ] and ventilatory conditions, such as airway pressure, were not assessed. Seventh, this was a single-center analysis that included a small number of events, although the patient characteristics shown in Table 1 were comparable to those in a previous Japanese database study [ 38 ].…”

Background The impact of intraoperative pulmonary hemodynamics on prognosis after off-pump coronary artery bypass (OPCAB) surgery remains unknown. In this study, we examined the association between intraoperative vital signs and the development of major adverse cardiovascular events (MACE) during hospitalization or within 30 days postoperatively. Methods This retrospective study analyzed data from a university hospital. The study cohort comprised consecutive patients who underwent isolated OPCAB surgery between November 2013 and July 2021. We calculated the mean and coefficient of variation of vital signs obtained from the intra-arterial catheter, pulmonary artery catheter, and pulse oximeter. The optimal cut-off was defined as the receiver operating characteristic curve (ROC) with the largest Youden index (Youden index = sensitivity + specificity – 1). Multivariate logistic regression analysis ROC curves were used to adjust all baseline characteristics that yielded P values of < 0.05. Results In total, 508 patients who underwent OPCAB surgery were analyzed. The mean patient age was 70.0 ± 9.7 years, and 399 (79%) were male. There were no patients with confirmed or suspected preoperative pulmonary hypertension. Postoperative MACE occurred in 32 patients (heart failure in 16, ischemic stroke in 16). The mean pulmonary artery pressure (PAP) was significantly higher in patients with than without MACE (19.3 ± 3.0 vs. 16.7 ± 3.4 mmHg, respectively; absolute difference, 2.6 mmHg; 95% confidence interval, 1.5 to 3.8). The area under the ROC curve of PAP for the prediction of MACE was 0.726 (95% confidence interval, 0.645 to 0.808). The optimal mean PAP cut-off was 18.8 mmHg, with a specificity of 75.8% and sensitivity of 62.5% for predicting MACE. After multivariate adjustments, high PAP remained an independent risk factor for MACE. Conclusions Our findings provide the first evidence that intraoperative borderline pulmonary hypertension may affect the prognosis of patients undergoing OPCAB surgery. Future large-scale prospective studies are needed to verify the present findings.
