A COMPARATIVE STUDY OF PHENYLEPHRINE AND EPHEDRINE IN CONTROLLING HYPOTENSION IN PARTURIENTS AFTER SPINAL ANESTHESIA IN CAESAREAN SECTION SURGERIES.

Dr. B. Ravi, Dr. Saranya Ravi

Abstract :

HYPOTENSION AFTER SPINAL ANESTHESIA (LESS THAN 90 mm.Hg SYSTOLIC OR MORE THAN 20% FALL FROM BASELINE BP)IN CAESAREAN SECTION SURGERIES IS A SERIOUS COMPLICATION CAUSING NAUSEA, VOMITING AND DECREASED UTERINE PERFUSION AND FOETAL BLOOD FLOW. THIS HYPOTENSION IS DUE TO 1.SUPINE HYPOTENSION DUE TO AORTO –CAVAL COMPRESSION BY GRAVID UTERUS AND 2.DECRESED VENOUS RETURN TO HEART BY PERIFERAL VASCULAR DILATATION CAUSED BY SPINAL SYMPATHETIC BLOCK.VASO PRESSORS LIKE PHENYLEPHRINE AND EPHEDRINE ARE WIDELY USED AROUND THE WORLD TO MANAGE THE DANGEROUS HYPOTENSION FOR BETTER MATERNAL AND FOETAL OUTCOMES
