The aim of this clinical trial was evaluation the efficacy of six combinational methods for preventing maternal hypotension after spinal anesthesia for cesarean delivery. A total of 300 ASA physical status I-II women undergoing elective cesarean section with spinal anesthesia were randomized to six groups: 1-Ringer's lactate (RL) solution (15 ml/kg) and colloid (Hemaxel) preload (7ml/kg); 2- RL solution preload (15 ml/kg) and ephedrine(15 mg, IV, bolus); 3-RL solution preload (15 ml/kg) and leg bandage; 4-Colloid (Hemaxel) preload (7ml/kg) and ephedrine(15 mg, IV, bolus); 5-Colloid (Hemaxel) preload (7ml/kg) and leg bandage; 6-Ephedrine (15 mg, IV, bolus)and leg bandage.The crystalloid and colloid solution infused 30 minutes before spinal anesthesia and ephedrine and leg bandage administered immediately after spinal anesthesia in above groups.Spinal anesthesia was done using bupivacaine 0.5 percent 2.5 ml in all patients. Participants were including parturients with ASA physical status I-II, scheduled for elective cesarean section, under spinal anesthesia and excluded with suspicious to bleeding disturbances, atopia, diabetes mellitus, presence of liver or kidney diseases, drugs abuse, hypertension of pregnancy, preeclampsia. Maternal blood pressure and heart rate compared on arrival to operating room, immediately after anesthesia (time 0), and minutes 3, 5, 15, 20, 25, 30, 35, and 60 after spinal injection among the groups.
