Comparison of the hemodynamic effects of lateral and sitting positions during induction of spinal anaesthesia for caesarean section using hyperbaric bupivacaine

Abstract

Background: Central neuraxial blocks result in sympathetic block, sensory analgesia, and motor blockade. Hypotension is the most common undesirable consequence after spinal anaesthesia in participants. Maternal position and density of bupivacaine during induction of spinal anaesthesia are two most important factors which determine the speed of onset of sensory block and subsequently the hemodynamic outcomes. This study is to compare the Hemodynamic effects of lateral and sitting Positions during induction of spinal anaesthesia for caesarean section using hyperbaric bupivacaine. Materials and Methods: A Prospective, Randomised, interventional study was conducted over 100 ASA grade 1, 2 and 3 and aged 25 to 35 years patients posted for caesarean section under spinal anaesthesia for the year 2022. Patients were randomly distributed in two groups prior to induction: Group S, sitting position and Group L, lateral position, after induction both the groups’ patients were returned to supine position. All observation were recorded and Chi-square test was used to analyze categorical data. P value
