Comparison Of Hemodynamic Effect Caused By Intrathecal Low Dose Administration Of 0.5% Against 0.75% Hyperbaric Bupivacaine In Patients Undergoing Lower Limb Surgery Under Unilateral Spinal Anaesthesia.

Background: Spinal anaesthesia has its unique place in modern anaesthetic practice. In past, most of the surgeries, irrespective of the site of surgery, were performed in general anaesthesia but now in the modern anaesthetic field, spinal anaesthesia has markedly replaced general anaesthesia, specifically in obstetrics, lower limbs, and abdominal surgeries.

Methods: A total of 100 patients fit to undergo lower limb surgery between the ages of 20 to 70 years were included in the study.
