Intramuscular ephedrine for prophylaxis of hypotension secondary to subarachnoid anesthesia in cesarean sections
Abstract
Introduction: arterial hypotension is the most frequent adverse effect of subarachnoid anesthesia in cesarean operations, it represents a serious risk for both mother and child, hence the need for prophylaxis.
Objective: to evaluate the efficacy of the use of ephedrine intramuscularly with respect to the traditional method in the prevention of arterial hypotension secondary to subarachnoid anesthesia.
Method: an experimental, controlled and randomized study was carried out in the General Provincial Teaching Hospital "Dr. Antonio Luaces Iraola" of Ciego de Ávila, from November 2011 to June 2014. It worked with 200 patients, who met the criteria established in the study, which were assigned to two groups: one to which ephedrine was applied intramuscularly, added to the usual treatment with isobaric bupivacaine 0,5 % (experimental group) and another to which only the technique of habitual use was applied (control group).
Results: the incidence of hypotension was lower in the experimental group and stability in heart rate was found. The number of ephedrine boluses used in the experimental group was lower than in the control group, as well as the appearance of complications.
Conclusions: the intramuscular ephedrine proved to be an effective method as prophylaxis of arterial hypotension in patients operated on by cesarean sectionDownloads
