Characteristics may limit its use for ambulatory surgery, including delayed ambulation, risk of urinary retention, and pain after block regression. The changing trend of surgical practice from an inpatient to outpatient convention has urged us to modify our anesthetic drug to suit the ambulatory setting. The primary goal of ambulatory anesthesia is rapid recovery leading to early patient discharge with minimal side effects. Hence based on above findings the present study was planned for Comparative Assessment of 2-Chloroprocaine 1% versus Hyperbaric Bupivacaine 0.5% for Administration in Subarachnoid Block for Pregnant Females Undergoing Elective Caesarean Section. The present study was planned in Department of Anaesthesiology and Critical Care, Darbhanga Medical College and Hospital, Darbhanga, Bihar, India. Total 80 females undergoing the elective lower segment caesarean surgery under subarachnoid block were enrolled in the present study. The females were divided on two study groups as Group I and Group II. Group I females were injected 2.5 ml of 1% preservative free 2-chloroprocaine and Group II were injected 2ml of 0.5% hyperbaric bupivacaine intrathecally. Patient in sitting or lateral position with the help of an assistant, under aseptic precaution and draping subarachnoid block was performed using 25 G Quincke’s spinal needle at L3 -L4 or L2 -L3 spinal inter space and after ensuring free flow of clear CSF. The data generated from the present study concludes that low dose 1% 2-chloroprocaine 25 mg can be a good alternative to 0.5% hyperbaric bupivacaine 10 mg for intrathecal use in an uncomplicated elective lower segment caesarean section.
