Abstract :

Back Ground: Elective surgical repair of an inguinal hernia is one of the most common surgical procedures. Ilioinguinal and iliohypogastric nerves block have been shown to significantly reduce pain associated with herniorraphy, regardless of whether the blocks are used as the primary anesthetic, or for pain control after general or spinal anesthesia. Use of ultrasound to guide placement of needles and catheters for regional anesthesia and analgesia has become increasingly popular. Aim: To compare the efficacy and duration of pain relief after ultrasound guided verses conventional ilioinguinal and iliohypogastric nerve block. To study time of requirement of supplemental parenteral analgesics in both the groups. To compare hemodynamic stability in both the groups. Materials and Methods: This prospective, randomized and double blinded study was conducted in a tertiary care hospital. Data was collected from adult males of American Society of Anesthesiologists (ASA) physical status I and II scheduled for elective open surgery of inguinal hernia repair. Sixty patients were divided into two groups, group A and group B, of 30 each, using computer generated randomized sequence. The presence and severity of pain, was assessed by visual analogue scale(VAS) in the post anesthesia care unit upto 24 hours after the nerve blockade. Results: Patient characteristics were collected and subjected to ANOVA and students t–test. It revealed that ultrasound guided nerve block had prolonged duration of blockade compared to conventional method with a significant P valve of 0.041. And comparison of the success rate of nerve block between the two groups showed a very significant P valve of 0.004 confirming that ultrasound guidance has greater efficacy than the conventional nerve block Conclusion: Ultrasound guided ilioinguinal / iliohypogastric nerve block has greater success, efficacy and longer duration of pain relief than conventional nerve block. Hemodynamic stability was same in both the groups.
