A randomized controlled trial on the effectiveness of laparoscopic-guided transversus abdominis plane block in patients undergoing laparoscopic IPOM plus.

ABSTRACT

INTRODUCTION: Ventral hernia repairs, particularly laparoscopic ventral hernia repair (LVHR), have become common procedures among general surgeons worldwide. Despite the benefits of LVHR, acute postoperative pain remains a significant concern. Transversus abdominis plane (TAP) blocks have been employed to alleviate postoperative pain in various laparoscopic procedures. This study aimed to assess the effectiveness of laparoscopic-guided TAP block in laparoscopic IPOM plus and its impact on postoperative pain and analgesic requirements. MATERIALS AND METHODS: A randomized controlled trial was conducted at a tertiary care center in India involving 72 patients undergoing laparoscopic IPOM plus. Patients were randomized into two groups Group I received laparoscopic-guided TAP block, while Group II received standard general anesthesia without TAP block. Pain scores were assessed at 6, 12, and 24 h postoperatively using the numerical rating scale. Postoperative analgesic requirements were also recorded. RESULTS: Group I demonstrated significantly lower pain scores at 6 and 24 h postoperatively compared to Group II. The need for additional analgesics was significantly lower in Group I (13.8%) compared to Group II (72.2%). There were no significant differences in age, BMI, duration of surgery, or other demographic characteristics between the two groups. CONCLUSION: The findings of this randomized controlled trial demonstrate the effectiveness of laparoscopic-guided TAP blocks in reducing postoperative pain and analgesic requirements after laparoscopic IPOM plus.
