Abstract
Background: Anesthesia management has critical role in the effectiveness of laparoscopic sleeve gastrectomy (LSG), due to the significant anatomic, physiological, and pathological challenges in obese population.
Aim: To report and discuss our anesthetic management outcomes in patients who underwent LSG.
Methods: Data of 81 obese patients who underwent LSG were retrospectively analyzed. All techniques used in the anesthesia management were compared between each other in terms of complications, duration of surgery intensive care unit (SICU) stay, total hospitalization time. Results: Two different protocols were used for induction of anesthesia: propofol-based protocol (n=27) and thiopental sodium-based protocol (n=54). Anesthesia was maintained by sevoflurane (n=59) or desflurane (n=22) inhalation. All anesthesia-related complications were found in thiopental sodium group (p=0.026). Sevoflurane and desflurane were similar in anesthesia-related complication, duration of SICU stay and total hospitalization time. Presence of obstructive sleep apnea (OSA) and coexisting chronic disease were found to be associated with longer SICU stay (p<0.001).
Conclusion: Propofol seemed to be safer than thiopental sodium in terms of anesthesia-related complication. Sevoflurane and desflurane were similar in anesthesia-related complication, duration of SICU stay and total hospitalization time. Presence of OSA was significantly associated with increased risk of anesthesia-related complication and longer SICU stay.
