Background and Aims: Anesthesia in obese patients is difficult due to associated comorbidities and altered physiology. Desflurane and sevoflurane have a low fat-blood solubility coefficient and are better suited in these patients to achieve a rapid emergence. We studied BIS guided drug titration to compare the postoperative recovery characteristics and cognitive function of desflurane versus sevoflurane in obese patients undergoing laparoscopic abdominal surgeries. Material and Methods: After institutional ethics committee approval and written informed consent, sixty obese patients (BMI ≥30 kg/m2) were randomized to receive either BIS guided desflurane or sevoflurane. Recovery was assessed by time taken for eye opening on verbal command, sustained head lift for 5 s, and extubation and orientation to time, place, and person after discontinuation of volatile anesthetic agent. For cognitive function, time taken to complete Mini mental state examination (MMSE) score to baseline was compared in both study groups. Results: Difference of time taken for eye opening on verbal command, sustained head lift for 5 s, and extubation and orientation to time, place, and person was not significant between both anesthetic groups. Patients in sevoflurane group took significantly (P-value = 0.001) less time (40.07 ± 13 min) to achieve preoperative MMSE score than desflurane group (51.2 ± 11.7 min). Conclusion: Both desflurane and sevoflurane have similar recovery profile in obese patients when anesthetic concentration is carefully titrated. Reversal of cognitive function is significantly earlier in obese patients anesthetized with sevoflurane.
