Abstract:
Objective To investigate the clinical efficacy of dexmedetomidine combined with ropivacaine for ilioinguinal and iliohypogastric nerve block in elderly patients undergoing inguinal her-nia surgery.Methods Sixty elderly patients undergoing inguinal hernia surgery were randomly divided into dexmedetomidine group (group D)and control group (group C),30 patients in each group.All patients received ilioinguinal and iliohypogastric nerve block by the same anesthesiologist. 0.375% ropivacaine and dexmedetomidine 1 μg/kg 20 ml were used in ilioinguinal and iliohypogastric nerve block in group D,while 0.375% ropivacaine 20 ml were used in ilioinguinal and iliohypogastric nerve block in group C.Sensory block onset time and blockade duration were recorded.Side effects were recorded in both groups.Results Sensory block onset time in group D was significantly shorter than that in group C (10.6±4.3 min vs 14.4±5.1 min,P <0.05).Sensory block durations in group D was significantly longer than that in group C (832.7±136.6 min vs 669.8±140.1 min,P <0.05). There were two bradycardia cases in group D.No adverse reactions or anaesthesia complications oc-curred in all patients following postoperative follow-up.Conclusion Dexmedetomidine combined with ropivacaine can be used in ilioinguinal and iliohypogastric nerve block safely,and dexmedetomidine shortens the onset time and prolonged the duration of sensory block.
