Comparison of Ilioinguinal-İliohypogastric Nerve Block versus Spinal Anesthesia Techniques for Single Sided Inguinal Herniorrhaphy

Abstract

OBJECTIVES: The aim of the study is to compare the hemodynamic effects, postoperative analgesia, time to achieve discharge criteria, and patient-surgeon satisfaction of patients who are assigned for single sided inguinal hernia repair operated under iliohypogastric ilioingıinal nerve block (IHNB) or spinal anesthesia.METHODS: Twenty-five ASA I-III patients in Group S received 15 mg 0.5% hyperbaric bupivacaine intrathecally, and 25 ASA I-III patients in Group I received IHNB with 20 mL 0.5% plain bupivacaine.RESULTS: Mean block application duration (16.4±3 vs 6.5±2.1 min), mean sensory block rise time (25.2±5.1 vs 6.9±3.4 min), and time to sensory block termination (262.4±65.2 vs 116.6±102.5 min) was found to longer in Group I with respect to Group S (p<0.001). Mean time to first mobilization (307.1±146.9 vs 456.9±131.7 min), and mean time to meet discharge criteria (4.6±0.8 vs 8.1±2.7 hr) was shorter in group I. Mean VAS scores in postoperative 1, 2, 4 and 6 th and mean tramadole consumption in 24 hr (375.6±113.1 vs 180.5±17.9 mg) were higher in Group S (p<0.001). Hemodynamic parameters, patient and surgeon satisfaction were comparable (p>0.05).CONCLUSION: IHNB provides longer postoperative analgesia and earliar discharge, although takes more time to perform and to produce maximum effect, for single sided inguinal henia repair.
