Application of laryngeal mask airway in obese male patients undergoing ophthalmic day surgery: a retrospective study
Journal Title: Eye Science (Yanke Xuebao) - Year 2024, Vol 39, Issue 12
Abstract
[Objective:] General anesthesia using laryngeal mask airway (LMA) ventilation can facilitate ambulatory ophthalmic surgery, however, there remains debates about the use of LMA for obese patients. This study retrospectively analyzed the application of LMA in obese patients for ambulatory ophthalmic surgery. [Methods:] In this retrospective study, we analyzed all patients with a BMI≥25 kg/m² who underwent ambulatory ophthalmic surgery under general anesthesia at the Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2021 to March 2024. The patients were divided into two groups: overweight group (BMI 25~<30 kg/m²) and obese group (BMI ≥30 kg/m2) . We compared the changes in hemodynamics and oxygen saturation at the several time points, baseline after entering operating room(T1), anesthesia induction (T2), LMA insertion (T3), start of surgery (T4), 10 minutes after surgery (T5), surgery completion (T6), transfer to PACU (T7), and LMA removal (T8); and analyzed the changes in respiratory parameters of the patient at T3, T4, T5, T6, and T8 time points between both groups. We also observed the differences in success rate of LMA insertion and ventilation and PACU stay time as well as time to discharge home between two groups. [Results:] 118 cases were found suitable for the final analysis and divided into overweight group (n=57) and obese group (n=61). All patients in the two groups uneventfully completed the ophthalmic ambulatory surgery and discharged home under the laryngeal mask airway ventilation, none of patients in both group displayed LMA ventilation failure. The hemodynamics and oxygen saturation in both groups were stable during perioperative period(P>0.05). The peak airway pressures in obese group were dramatically increased than in overweight group at T3, T4, T5, T6 and T8 time points (P<0.05), and the incidences of adverse respiratory events in obese group were significant higher than in overweight group (P<0.05). The PACU stay time was comparable in both groups (P>0.05). [Conclusion:] LMA can be safely used for obese patients undergoing ophthalmic surgery, high BMI is related to high peak airway pressures.
