This multicenter cohort research included patients with morbid obesity who had LSG between January 2021 and December 2022. The patients included in the study were allocated to one of two treatment groups that were not randomized but the patients were categorized according to the time of surgery: Group A received Pethidine alone in the period between January 2021 and December 2021, while Group B got Tramadol with pethidine in the period between January 2022 and December 2022. Doses were based on the patient's actual body weight.
Postoperative pain remains a very UNPLEASENTevent, particularly in morbidly obese patients that may be associated with obstructive sleep apnea. Bariatric surgery patients must get safe and efficient analgesia, which is essential given that up to 45 % of patients report substantial pain in the first two days following surgery. The study's purpose was to compare the efficacy and safety of combined tramadol with pethidine versus pethidine alone and to assess their impact on postoperative pethidine requirements after LSG for morbidly obese patients
