Abstract
INTRODUCTION: Spinal anesthesia for below umbilical surgery causes almost inevitable sympathetic block and decreased venous return to the heart. It results in hypotension and decreased cardiac output. The prevention of spinal hypotension appears more likely to decrease the frequency and severity of associated adverse symptoms than the treatment of established hypotension. Physical intervention as lower limb elevation is used for prevention of hypotension and may act by minimizing venous pooling of blood in the lower limbs and lower abdomen. AIMS: To compare the effects of lower limb elevation as a tool for prevention of hypotension during spinal anesthesia for below umbilical surgeries. METHODOLOGY: Our study was conducted in department of Anesthesiology, S.S. Medical College, Rewa. Hundred patients scheduled for elective below umbilical surgeries were randomized into two groups. In group A patients, lower limbs were elevated to approximately 30 degrees and no intravenous fluid was given preoperatively, while in group B patients 10-20 ml/kg of intravenous crystalloid was given as preloading and patient was in neutral position. RESULTS: There was less hypotensive episodes, intravenous fluid requirement, urinary retention; nausea & vomiting in group A patients. Also there was less subjective blood loss in group A
