Table 2 Intraoperative management. Paturient were monitored intraoperatively for degree of hypotension caused by the intrathecal injection of local anesthetic; the doses of ephedrine administered to manage the hypotension; exteriorization of uterus; and the duration of surgery. Data were statistically significant at P < 0.05 compared with control
