Comparison of subcostal transversus abdominis plane block with port site infiltration of local anaesthesia in laparoscopic cholecystectomy

Abstract

Objective: To compare the efficacy of ultrasound guided subcostaltransversus abdominis plane block and port site infiltration of local anaesthesia in patients undergoing laparoscopic cholecystectomy. Study Design: Comparative cross sectional study. Place and Duration of Study: Anesthesiology department, Pak Emirates Military Hospital, Rawalpindi, from Jan to Jun 2019. Methodology: A sample size of 62 patients calculated by World Health Organization calculator were randomized in a double-blind study to undergo Sub costal transversus abdominis plane block or port site infiltration by non-probability, consecutive sampling into two equal groups. Group A received sub costal transversus abdominis plane block and group B local anaes-thetic. Postoperative pain perception was measured using visual analogue scale. Results: The mean age of patients in group A was 33.39 ± 8.91 years and in group B was 33.77 ± 8.45 years. Out of 62 patients 38 (61.29%) were males and 24 (38.71%) were females. Mean pain score in group A (ultrasound guided sub costal transversus abdominis plane block) was 1.61 ± 0.91 while in group B (port site infiltration of local anaesthetic) was 3.61 ± 1.05 (p-value 0.0001). Conclusion: The mean pain score was less following use of ultrasound guided sub costal transversus abdominis plane block in patients undergoing laparoscopic cholecystectomy as compared to port site infiltration of local anaesthesia.
