Comparison the effects of prilocaine and the addition of dexketoprofen and dexamethasone to prilocaine for intravenous regional anesthesia

Objectives: The aim of this study was to compare the anesthetic and analgesic effects ofprilocaine alone, prilocaine added dexketoprofen and dexamethasone during intravenous regional anesthesia (IVRA). Methods: Forty five patients undergoingforearm or hand surgery were randomly assigned to one of three groups to receive (Group P) 3 mg/kg 0.5% prilocaine; (Group PDK) 3 mg/kg 0.5% prilocaine plus 50 mg dexketoprofen; (Group PDM) 3 mg/kg 0.5% prilocaine plus 8 mg dexamethasone in total 40 ml volume for IVRA. The onset and duration of sensory and motor blocks, hemodynamic datas, duration of analgesia and tourniquet, time to first analgesic requirement, visual analog scale (VAS), total analgesic consumption in 24 hours and patient satisfaction score were assessed and recorded. Results: Time to onset of sensory block was found to be longer in Group P (p<0.05), though no significance was found according to sensory block recovery times amoung groups. Time to onset of motor block was found to be longer and recovery time of motor block was found to be shorter in Group P (p<0.05). Time to first analgesic requirement was found to be longer in Group PDK,and was found to be high in Group PDM than Group PDK(p<0.05). The VAS scores was found to be high and patient satisfaction scale was found to be low in Group P (p<0.05). Conclusion: The addition of dexketoprofen and dexamethasone to prilocaine during IVRA improves the quality of both anesthesia and analgesia moreover dexketoprofen provides beter postoperative analgesia during the first 24 hour after surgery.
