A Comparative study of intrathecal 1% Chlorprocaine and 0.5% Ropivacaine in perianal surgeries. To compare the time of onset, height of block, intensity of sensory and motor blockade, duration of analgesia, time to ambulation, time to discharge as well as the incidence of side effects between the two groups. Patients who are scheduled for elective peri anal surgery are included after the pre anaesthetic assessment if they meet the inclusion criteria Group C – intrathecal 4.0 mL of 1% Chlorprocaine Group R – intrathecal 4.0 mL of 0.5% Ropivacaine There was no significant hemodynamic changes & com plicationsin the both groups. Average discharge time was significantly lower with chlorprocaine as compared to ropivacaine. Intrathecal administration of 40 mg of local anaesthetic 1% Chloroprocaine for surgeries of short duration, when compared with 0.5%,ropivacaine resulted in rapid onset with quicker recovery from anaesthesia and a shorter time for first rescue analgesia and unassisted ambulation.
