مقایسه انفوزیون افدرین و افزایش حجم داخل عروقی با کریستالوئید (سرم پره لود) در متعادل نگه داشتن فشار خون در خانم های بارداری که تحت بیحسی اسپاینال جهت عمل سزارین قرار گرفته اند

Hypotention is hazardous for fetus and mother under spinal anesthesia in cesarean section. Prophylactic effect of crystalloid preload and ephedrine infusion were compared in preventing of hypotention in these patients. From the cases, 44 women candidate for elective cesarean section were randomly divided in two groups. In first group, 15 ml per kg Ringer infused before spinal anesthesia. In the second group, Ephedrine infusion 0.25 mg/kg/3 min started immediately after spinal. During the section, BP was more stable in second group than the first group. Therefore ephedrine infusion seems to be more effective in controlling of BP in these patients.
