Abstract Background The relationship between intraoperative low bispectral index (BIS) values and poor clinical outcomes has been controversial. Intraoperative hypotension is associated with postoperative complication. The purpose of this study was to investigate the influence of intraoperative low BIS values and hypotension on postoperative mortality in patients undergoing major abdominal surgery. Methods This retrospective study analyzed 1,862 cases of general anesthesia. We collected the cumulative time of BIS values below 20 and 40 as well as electroencephalographic suppression and documented the incidences in which these states were maintained for at least 5 minutes. Durations of intraoperative mean arterial pressures (MAP) less than 50 mmHg were also recorded. Multivariable logistic regression was used to evaluate the association between suspected risk factors and postoperative mortality. Results Ninety-day mortality and 180-day mortality were 1.5% and 3.2% respectively. The cumulative time in minutes for BIS values falling below 40 coupled with MAP falling below 50 mmHg was associated with 90-day mortality (odds ratio, 1.26; 95% confidence interval, 1.04-1.53; P = .019). We found no association between BIS related values and 180-day mortality. Conclusions Delicate adjustment of anesthetic depth is important to avoid excessive brain suppression and hypotension, which could be associated with postoperative mortality.

The Relationship

This study aimed to investigate the relationship between the bispectral index and the National Institutes of Health Stroke Scale (NIHSS) score in patients admitted to the emergency department with a first-time acute ischemic stroke. Methods: This prospective, observational study was conducted with patients admitted to our clinic with acute ischemic stroke symptoms. Patients with known cranial pathologies, such as space- occupying lesions, those with a history of clinically significant cerebrovascular events or sedative drug administration, and those with altered consciousness due to metabolic causes were excluded from the study. The National Institutes Health Stroke Scale scores were recorded by the clinician. Cerebral arterial territories were assessed on DWI and CT. The relationship between the NIHSS score and bispectral index was evaluated. Results: Forty-three patients were included in the study. The mean bispectral index of the cases was 84.23 ± 9.50. There was no significant correlation between the bispectral index values and the NIHSS score (p<0.05). Conclusion: In our study, the bispectral index values were decreased due to ischemic stroke. The results should be reevaluated studies conducted with larger series to reveal the relationship between infarcted territories, NIHSS score, bispectral index, and the GCS score.

AbstractTo continuously and noninvasively monitor the cerebral tissue oxygen saturation (StO2) and hemoglobin concentration (gasHb) in cardiac surgery patients, a method combining the use of a cerebral tissue oximeter using near infrared time-resolved spectroscopy (tNIRS-1) and the bispectral index (BIS) was developed in this study. Moreover, the correlation between the estimated hemoglobin concentration (estHb), measured via tNIRS-1, and the hemoglobin concentration (gasHb), analyzed using a blood gas analyzer, were compared. The relationship between the BIS and gasHb was also examined. Through the comparison of BIS and StO2 (r1), and estHb and gasHb (r2), the correlation between the two was clarified with maximum r1 and r2 values of 0.617 and 0.946, respectively. The relationship between BIS and gasHb (r3), showed that there was a favorable correlation with a maximum r3 value of 0.969. There was also a continuous correlation between BIS and StO2 in patients undergoing cardiac surgery. In addition, a strong correlation was found between estHb and gasHb, and between BIS and gasHb. It was therefore concluded that the combined use of BIS and tNIRS-1 is useful to evaluate cerebral hypoxia, allowing for quick response to cerebral hypoxia and reduction of hemoglobin concentration during the operation.
