Abstract
Maternal hypotension is a common complication after spinal anesthesia for cesarean section (CS). In this study we investigated the role of passive leg raising (PLR) as a method for prevention of post-spinal hypotension for cesarean section (PSHCS). One hundred and fifty full term parturients scheduled for elective CS were included in the study. Patients were randomized into two groups: passive leg raising group , PLR (, n=75) and control group, group C (n=75). Spinal block was performed in sitting position after administration of 10mL/Kg Ringer{u2019}s lactate as fluid preload. After successful intrathecal injection of local anesthetic, Patients were positioned in the supine position. Leg elevation was performed for PLR group directly after spinal anesthesia and maintained till skin incision. Intraoperative hemodynamic parameters (Arterial blood pressure and heart rate), intra-operative ephedrine consumption, incidence of PSHCS, and incidence of nausea and vomiting were reported. PLR group showed lower incidence of PSHCS (34.7% Vs 58.7 %, P=0.005) compared to the control group. Arterial blood pressure and heart rate readings were comparable between both groups, however, PLR showed less ephedrine consumption 4.9±7.8 mg Vs 10±11 mg, P=0.001. PLR performed immediately after spinal block reduces the incidence of hypotension in parturients undergoing elective CS
