Effect of intraperitoneal lidocaine administration versus traditional analgesics only on postoperative pain control in laparoscopic bariatric surgeries.

Background: Opioids have traditionally been the primary treatment for managing pain during surgical procedures.Regrettably, there have been recent concerns regarding the potential adverse consequences of these substances. Theintroduction of opioid-free anesthesia aimed to offer a safer option that would yield advantages and facilitate postoperative recovery. This study’s principal goal is to conduct a comparative analysis of the effects of intraperitoneal lidocaine injection and traditional analgesics only in the treatment of postoperative pain following laparoscopic bariatric surgeries.Patients and Methods: At a tertiary hospital, a prospective comparative study was carried out on a cohort of 50 individuals suffering from obesity with a body mass index (BMI) of 35 kg/m2. These patients were undergoing laparoscopic bariatric procedures. They were segregated into two distinct groups: in group A, a total of 25 patients were administered a solution consisting of 20 ml of lidocaine 2% diluted with 500 ml of normal saline for intraperitoneal irrigation along the stappled residual portion of the stomach and/or anastomosis area. In group B, 25 patients were solely administered analgesics.Results: There is a statistically significantly lower pain score at recovery, at 4 h and at 24 h in patients treated byintraperitoneal lidocaine than those treated by analgesics.Conclusion: Our results showed that intraperitoneal lidocaine administration showed lower pain scores and was moreeffective compared with analgesics exclusively for managing pain during laparoscopic bariatric surgeries.
