Effect of bispectral index monitoring on desflurane consumption, extubation and recovery times in anesthesia management for arthroscopic surgery

m: The bispectral index (BIS) assesses the hypnotic effects of anesthetic agents. It has been reported that the incidence of postoperative cognitive dysfunction is reduced, and wake-up and recovery times are shortened with the use of BIS monitoring. The aim was to evaluate the effect of BIS monitoring on hemodynamic parameters, recovery times, and desflurane consumption in patients who underwent arthroscopic surgery.
Material and Methods: The patients were classified into two groups: the control group, which received standard anesthesia monitoring, and the BIS group, which received both standard and BIS monitoring. The two groups were compared in terms of hemodynamic parameters, desflurane consumption, spontaneous eye-opening time, recovery time, and side effects.

Results: There were no significant differences between the groups in terms of the course of perioperative hemodynamic parameters over time. The groups were comparable regarding side effects, including hypotension, nausea, vomiting, bradycardia, and laryngospasm. Spontaneous eye-opening time and recovery time were shorter in the BIS group. The amount of desflurane consumed per unit time was found to be lower in the BIS group.
Discussion: BIS monitoring shortened desflurane consumption, spontaneous eye-opening, and recovery times, indicating that BIS monitoring can be safely used to monitor the depth of anesthesia by providing ideal inhalation anesthetic titration.
