Comparison between Ultrasound-Guided Transversus Abdominis Plane Block with Ilioinguinal or Iliohypogastric Nerve Block for Post-Operative Analgesia in Patients of Inguinal Hernia Repair

Abstract

Objective: To compare ultrasound guided transversus abdominis plane block with Ilioinguinal or iliohypogastric nerve block in terms of post-operative analgesia.

Study Design: Prospective, randomized single-blind study

Place and Duration of Study: This study was conducted at the department of anesthesia and intensive care of DG khan & Nishtar Hospital, Multan from April 2017 to April 2018.

Materials and Methods: Hospital local research and ethical committee approved the study protocols consent was taken after complete information of study. Allocation of the patients into groups was done by using lottery method. Patients were divided into two groups I and II. Main variables of the study are postoperative analgesia requirement, dose of diclofenac sodium and VAS score. SPSS software was used for data analysis.

Results: Mean duration of rescue analgesic requirement and dose of tablet diclofenac required per minutes of Group I was 322.05±21.87 minutes and 207.05±9.77 mg, respectively. While, the mean duration of rescue analgesic requirement and dose of tablet diclofenac required per minutes of Group II was 413.04±12.13 minutes and 175.28±9.71 mg, respectively. The difference was statistically significant.

Conclusion: We concluded that Ilioinguinal (IIH) and Iliohypogastric (IHN) nerve block reduced the rescue analgesic requirement as compare to ultrasound guided TAP block. Duration of post-operative analgesia is longer in IIIH/IHN block.
