Eficacia de bupivacaína 2mg/kg- buprenorfina 0.5mcg/kg Vs bupivacaíana 2mg/kg por vía caudal para analgesia postoperatoria en paciente pediátrico. Hospital Vicente Corral Moscoso y Hospital José Carrasco Arteaga, Cuenca, 2014

Abstract

Introduction: The regional anesthesia by caudal epidural block in the pediatric patient is more appropriate for lumbar block, by the relative ease of access once identified the anatomical points. At the end of the surgical procedure, postoperative pain can be treated effectively. To use this track it is possible to administer drugs that together with the effect of the local anesthetic will favor the patient and remain for a longer time without severe pain. Objective: To compare the postoperative analgesia of the caudal block with bupivacaine 2mg/kg Vs Bupivacaine 2mg/kg - Buprenorphine 0.5mcg/kg in the pediatric patient. Material and methods: controlled clinical trial randomized single-blind. This study will be carried out at Vicente Corral Moscoso and José Carrasco Arteaga Hospital. We randomly selected 84 pediatric patients, ASA physical status I and II, with no contraindications for flow anesthesia, scheduled elective way and emergency surgeries for lower abdominal and found the intensity of the pain through the scale and EVA CHEOPS; hemodynamic changes and the incidence of side effects. Analysis of variance ANOVA to compare the mean, it was considered results statistically to the values of p<0.05. Results: It was determined that the Bupivacaine 2mg/kg Buprenorphine+ 0.5mcg/kg is better to control the pain compared to Bupivacaine 2mg/kg in caudal block in children. Averages were obtained of pain intensity and lower for a longer time, values of p<0.05. There were no significant changes in averages of the heart rate with the use of bupivacaine alone. No significant changes were found with the mean systolic blood pressure, diastolic and oxygen saturation. The incidence of side effects was minimal, no significant differences were observed between the groups, p-value >0.05. Conclusions: with the use of bupivacaine 2mg/kg Buprenorphine+ 0.5mcg/kg is a better control of the intensity of the pain and for a longer time, with minimal side effects
