Abstract

The effect of the head-down tilt position after induction of spinal anesthesia for cesarean delivery on blood pressure and level of sensory block was examined. Patients were allocated randomly into two groups, the head-down tilt group (n = 17) and the horizontal group (n = 17). In the head-down tilt group, patients were positioned with a 10 degrees head-down tilt immediately after supine positioning, while those in the horizontal group were maintained in a horizontal position. All patients received 500 mL of lactated Ringer's solution intravenously over 10 minutes prior to spinal injection, a wedge was placed under the patient's right hip, and the operating table was rotated 5 degrees in a counterclockwise direction to provide left uterine displacement. Hypotension (defined as systolic blood pressure below 100 mm Hg) was treated with 5 mg ephedrine intravenously and an increase in the infusion rate of lactated Ringer's solution. The change in systolic blood pressure was expressed as percent change from the baseline value. Systolic blood pressure decreased 20% at 3 minutes after spinal block in both groups but recovered to half of this decrease. The incidence of postspinal hypotension was not different between the two groups. Th...Continue Reading
