Evaluation of Intramuscular Ephedrine Effects in Prevention of Hypotension During a Cesarean Section

Introduction: Cesarean is one of the most frequent of all surgical procedures in the world and our country. A regional anesthetesia is more often conducted for elective cesarean section particularly when maternal awareness is desirable. However, hypotension occurs frequently during spinal anesthesia. The aim of this study was to evaluate Intramuscular Ephedrine effects in the prevention of hypotension during a cesarean section. Material and Methods: In a randomized clinical trial at Resat Hospital 100 patients were selected and divided into two equal groups. One group was given 30 nag of Ephedrine intramuscularly and the other group underwent spinal anesthesia. Systolic blood pressure was measured before and after spinal anesthesia at 2.5, 5, 10, 15, 20, 30 minutes. Demographic and clinical data was assessed and analyzed with Spss-win computer software. Results: Intramuscular Ephedrine significantly reduced the hypotension in the Study group compared with the Control group. Systolic blood pressure at 2.5, 5, 10, 15, 20 and 30 minutes after the injection of Intramuscular Ephedrine and spinal anesthesia was significantly different in the two groups and occurrence of hypotension in the intervention group was lower than the comparison group (p<0.05) Conclusion: Prophylactic intramuscular ephedrine is effective in the prevention of hypotension associated with spinal anesthesia for elective cesarean section.
