Abstract: Aim: The aim of the study is to evaluate the effect of transversus abdominis plane block on chronic postoperative pain after inguinal hernia repair.
Methods: Prospective randomized double blinded study is conducted on 40 male patients posted for inguinal hernia repair under spinal anaesthesia. Divided into 2 equal groups. Group I received USG TAP block with 20 ml of 0.25% bupivacaine whereas Group II received 20 ml of normal saline (Placebo) at the end of surgery. Postoperative VAS scores, analgesic consumption, DN4 scoring at 3 and 6 months to evaluate chronic pain were studied.
Results: Forty male patients were enrolled. Postoperative VAS scores of Group I had improved scores than Group II. Analgesic consumption is also reduced in Group I compared to Group II (156.6 ± 48.3 vs 282.1 ± 43.2) which was statistically significant. Incidence of neuropathic pain in Group II was 5% at 3 months and 10% at 6 months; whereas in Group I one patient scored ‘3’ at 3 months which reduced to ‘2’ at 6 months. No restriction of daily activities present in Group I patient.
Conclusion: USG TAP block provided better postoperative VAS scores and analgesic consumption, along with the reduction in incidence of chronic pain than placebo.
