BACKGROUND The auditory evoked potential (AEP) index, which is a single numerical parameter derived from the AEP in real time and which describes the underlying morphology of the AEP, has been studied as a monitor of anesthetic depth. The current study was designed to evaluate the accuracy of AEPindex for predicting depth of sedation and anesthesia during sevoflurane anesthesia. METHODS In th...

BACKGROUND Hyperbaric and isobaric bupivacaine has been shown to reduce bispectral index (BIS) during spinal anesthesia. The aim of this study was to compare the effect of isobaric bupivacaine and hyperbaric bupivacaine on the BIS during cesarean section with spinal anesthesia. MATERIALS AND METHODS In this double-blind randomized controlled clinical trial, 84 pregnant women with ASA (America...

Postoperative cognitive dysfunction is a common complication in the elderly patients receiving desflurane anaesthesia. The bispectral index score (BIS) -targeted desflurane anaesthesia may hasten the recovery and cognitive function in the elderly patients after spine surgery. Forty patients aged >60 yr., scheduled for elective spine surgery were randomly allocated to BIS targeted (n=20) and MAC...

BACKGROUND The bispectral (BIS) index is a processed electroencephalogram (EEG) parameter with extensive validation and demonstrated clinical utility. The study aimed to investigate the correlation between the BIS index and the prognosis of patients with coma in the ICU. METHODS A total of 208 patients with coma in the ICU were enrolled in this study. According to the BIS value, the patients ...

OBJECTIVE In this study, we aimed to compare Bispectral Index (BIS) monitoring with the conventional anaesthesia approach based on haemodynamic changes in terms of anaesthetic agent consumption, haemodynamic recordings, recovery time and cost. METHODS This study was performed in 82 patients, aged 20 to 60 years, who were operated for supratentorial mass and were graded ASA I or II. Cases were...

AIM To evaluate the impact of bispectral index (BIS) monitoring on the consumption of propofol and recovery from anesthesia compared to the standard clinical practice in children. BACKGROUND Titrating propofol administration using BIS reduces its requirement and shortens the recovery from anesthesia in adults. However, there is still mixed evidence for utility of anesthesia depth monitors in ...

Introduction. The purpose of this study was to examine the differences in temperament between So-Yang (SY) and So-Eum (SE) Sasang types using Behavioral Inhibition System/Behavioral Activation System (BIS/BAS) scale to elucidate the biopsychological mechanism underlying the Sasang typology, a traditional Korean personalized medicine. Methods. 248 university students were categorized into three ...

054 was initiated using the TCI method. The dose of propofol was titrated to achieve a BIS of 50 and achieve an adequate level of anesthesia: asleep but not responding to stimulation. Endotracheal intubation was not performed, and spontaneous breathing was maintained. The level of anesthesia was maintained at BIS 30-50 by adjusting the target propofol level using TCI (Figure 1). Without BIS, Th...
