Eficacia anestésica y duración analgésica de la bupivacaína al 0.25% + morfina vs bupivacaína al 0.25% en bloqueo del plexo braquial para cirugía de miembro superior en pacientes del Hospital Vicente Corral Moscoso, Cuenca 2014

Abstract

Introduction: Surgery of men in certain cases can be a challenge to the anesthesiologist that warrants of the domain of certain techniques of regional anesthesia and management of complications and analgesia in the first 24-48 hours. Objective : To compare the effectiveness between anesthetic bupivacaine 0.25% + morphine and 0.25 % bupivacaine alone in the blockade of the brachial plexus for surgery of the upper limb at the Hospital Vicente Corral Moscoso, Cuenca 2014. Methodology: design a randomized clinical study single-blind, to assess the effect of the addition of bupivacaine more morphine vs. bupivacaine alone in patients older than 18 years operated with supraclavicular brachial plexus block. The Group I patients received bupivacaine 0.25 % 75 mg in a total volume of 30 ml and the patients of the Group II were treated with 0.25 % bupivacaine 75 mg + morphine 50 ug/kg in a total volume of Results: the study groups were comparable in age, sex, type of intervention, weight, height and surgical time. A significant difference was found in the average latency of 7.05 minutes. The latency time is greater in the group of bupivacaine 11.16 minutes in relation to the group that received bupivacaine + morphine 4.11 minutes, p-value=0.000 . Similarly, the addition of bupivacaine + morphine provides more than double the time of 915.79 minutes analgesia when compared with the single administration of bupivacaine 280.53 minutes, p-value=0.000 . Side effects such as vomiting were higher for the addendum bupivacaine and morphine
