EFFICACY OF USING DELAYED SUPINE POSITIONING IN THE PREVENTION OF POST-SPINAL ANESTHESIA HYPOTENSION IN FEMALES UNDERGOING CAESAREAN DELIVERIES

Abstract

Background: After a subarachnoid block is administered after a caesarean section delivery, maternal hypotension is a
risky and frequent consequence. Maternal hemodynamic profiles are better affected when different pharmaceutical
techniques—such as ondansetron and norepinephrine—are used in conjunction with non-pharmacological techniques
during delayed supine positioning.
Aim: The current study set out to evaluate the risks and advantages of using both pharmaceutical and nonpharmacological
approaches in the prophylaxis of hypotension.
Methods: 170 subjects were randomly split into two groups and tested for the study. Group II (control) patients were
forced to lie down in a supine position as soon as the subarachnoid block was administered, while Group I subjects were
remained seated for two minutes following injection. Prophylactic intravenous infusion of norepinephrine and
ondansetron bolus prior to surgery was administered to both groups. Systolic blood pressure was measured in each patient
starting with the intrathecal injection and continuing until delivery.
