Abstract

Background: Postoperative analgesia for inguinal hernia procedures can be provided safely and effectively with USG guided TAP blocks. In the TAP block following inguinal hernia repair, we compared the analgesic effectiveness of dexmedetomidine and clonidine.
Materials and Methods: Seventy four patients undergoing inguinal hernia repair under spinal anesthesia were randomly divided in to Group LD (n=37) and Group LC (n=37). Patients in Group LD received a unilateral USG-guided TAP block with 0.5% levobupivacaine 18ml and dexmedetomidine 1 ?g/kg in NS to make a total 20ml at the conclusion of surgery after regression of sensory block to the T10 dermatome, whereas patients in Group LC received 0.5% levobupivacaine 18ml and clonidine 1 ?g/kg. Duration of postoperative analgesia, quality of analgesia (VAS), total rescue analgesic consumption in 24 hours and adverse effects were noted.
Result: Time for the initial application of rescue analgesia took substantially longer in Group LD (1006.49± 29.89 min) than in Group LC (512.35 ±27.14 min) (p ?0.0001). At 8h, 16h, and 20h postoperatively, Group LD had a significantly lower VAS score both at rest and during hip flexion. It was discovered that Group LD had considerably decreased overall analgesic consumption. Incidence of postoperative side effects was comparable between two groups.
Conclusion: In comparison to clonidine, TAP block with dexmedetomidine as an adjuvant to levobupivacaine greatly prolongs postoperative analgesia and lowers 24-hour analgesic use.
