AbstractCaesarean sections are routinely done under spinal anaesthesia using 0.5% hyperbaric bupivacaine that has a long duration of action. As most of the caesarean sections are of short duration, we decided to compare 1% 2-chloroprocaine with routinely used bupivacaine as chloroprocaine has rapid onset of action, producing an excellent sensory and motor blockade. After ethical committee clearance and informed written consent, 70 uncomplicated singleton parturients of ASA I and II posted for elective caesarean section were randomised into chloroprocaine (CP) and bupivacaine (B) group of 35 each.
Onset of sensory block in group CP was 1.71±0.62min and in group B was 2.31±0.63min. Onset of motor block in group CP was 2.54±0.88min and in group B was 2.66±0.76min. Mean time for maximum sensory block in group CP was 12.77±3.52min and in group B was 22.34±6.46min and time for maximum motor block in group CP was 9.14±2.23min and in group B was 10.86±2.18min. Two segment regression time in group CP was 39.34±4.46min and in group B was 63.14±4.7min. Mean duration of sensory block in group CP was 2.08±0.25hr and in group B was 3.60±0.27hr and duration of motor block in group CP was 1.07±0.14hr and in group B was 3.42±0.41hr. VAS scores in first 6hrs were lesser in group CP than group B. Onset, maximum time, duration of sensory and motor block were lower in group CP than group B. hemodynamic parameters were comparable between the groups with no side effects.
