COMPARATIVE STUDY OF THE EFFECTIVENESS OF SUBCOSTAL ANESTHESIA IN THE MANAGEMENT OF POSTOPERATIVE PAIN AFTER LAPAROSCOPIC CHOLECYSTECTOMY

The aim of the study was to compare the effectiveness of the subcostal block and the posterior TAP block in postoperative pain control in patients undergoing laparoscopic cholecystectomy. Materials and methods. The study was conducted at the Ismailov Center for High Technology Medicine from January to October 2024. It included 24 patients who underwent laparoscopic cholecystectomy. Patients with allergies to local anesthetics, extreme obesity, and liver diseases were excluded. The patients were randomly assigned to two groups receiving either a posterior TAP block or a subcostal block. The pain level was assessed 24 hours after surgery using a numerical rating scale (NRS). Results. The subcostal block provided a significant reduction in the average level of static pain 24 hours after surgery compared with the posterior TAP block. The greatest reduction in pain was observed 6 and 12 hours after surgery. Dynamic pain measures did not show a statistically significant difference between the groups. Conclusions. The subcostal block is a more effective method of controlling postoperative static pain in patients after laparoscopic cholecystectomy and may be the preferred choice for improving the quality of postoperative care.
