Comparative study of intrathecal isobaric and hyperbaric ropivacaine in cesarean delivery

Abstract

Spinal Anesthesia is a common safe, economical, easy to perform and effective technique which provides rapid and reliable anesthesia with muscle relaxation for pts undergoing lower abdominal surgery. Aim: To compare isobaric and hyperbaric ropivacaine in patients undergoing cesarean delivery Materials and Methods: Prospective Observational Clinical Study patients admitted for elective cesearan Delivery. The Duration of study is one year. 80 patients , aged 21 years to 30 years , belongs to ASA physical status 1 & 2, posted for elective Caesarean delivery under spinal Anaesthesia. These patients are divided into two groups of 40 patients Each. Group I : patients received 2ml of 0.75% Isobaric Ropivacaine (isobaric group), Group H: patients received 2 ml of 0.75% hyperbaric Ropivacaine in dextrose 50mg/ml (Hyperbaric group). There was no significant difference in the onset of sensory block. Time from injection to highest sensory block is significantly higher in isobaric group [ Group-I], when compared to hyperbaric group [ Group-H]. Time for onset of modified bromage grade 3 is longer in isobaric group than hyperbaric group. Time for motor regression is faster in hyperbaric group than in isobaric group so that early mobilization in hyperbaric group patients than isobaric group patients is possible.
