Corporación del bloqueo sensitivo con bupivacaina 0,5% 55 MG versus bupivacaina 0,5% 70 MG en igual volumen para anestesia epidural en cesárea. Hospitales Vicente Corral Moscoso y José Carrasco Arteaga, Cuenca 2013

Abstract

Objective. Comparation of sensory block produced by 55 mg bupivacaine 0.5 % + fentanylo 150 mcg + saline 3 ml 0.9 % versus 0.5 % bupivacaine 70 mg + 150 mcg fentanylo equal volume in through a catheter in epidural anesthesia for cesarean section.

Methodology. This was a randomized controlled design in which two groups of 64 maternal in each, group I received 55 mg bupivacaine 0.5 % + 150 mcg of fentanylo + 3 ml of 0.9 % saline at 17 ml is incluided group II volume and bupivacaine 0.5 % 70 mg + 150 mcg of fentanyl in 17 ml volume epidural catheter, which allowed us to determine the sensory block, metameric level, vital parameters and adverse effects when using different doses equal volume in epidural anesthesia for cesarean on patients attending Vicente Corral Moscoso and José Carrasco Arteaga Hospital in 2013.

Results. Full epidural blockade was significantly lower in the group in which lower doses of local anesthetic group 1 ( P = 0.001 ) was used, presenting more frequent pain ( P = 0.000) and tachycardia ( P = 0.041) . In group 2 there was a higher rate of hypotension ( P = 0.000) , nausea (P = 0.003) and vomiting ( P = 0.080 ).

Conclusion. The objective was met in this study provided us with results that reverse the trend for dose finding a high percentage of complete blocks in the group in which higher dose was used ( 92.2 % vs 64.1 %, P = 0.001). Concern persist that dose or to find that volume that is suitable for use in obstetric patients.
