Abstract : “To compare efficacy of 30 mg v/s 60 mg of 1% 2- Chloroprocaine as a spinal anaesthetic agent for short duration surgeries and early ambulation of patient” Observational double blind study was carried out on 60 patients (equal in both groups) belonging to ASA (American Society of Anaesthesiologists) grade I and II, aged between 18 to 65 years, including either gender, and meeting all inclusion exclusion criteria scheduled for elective lower abdominal surgical procedures under spinal anaesthesia after obatining Institute Ethics Committee Clearance. All cases will be completed within the stipulated time. The statistical analysis will be done by using ‘T Test’ for at 95% confidence interval. The sensory block onset, motor block onset, peak sensory and motor block, regression of sensory block by two segments and complete sensory block regression was quite fast with low dose of drug. The wearing off of motor block, mode of rescuse analgesia and voiding of urine was statistically non-significant. Urinary retention was not seen in any cases. The dermatomal level achieved with low dose was lower as comapred to the higher dose. Preservative free 1% 2-Chloroprocaine can be used as a drug for sub arachnoid block especially for day care surgeries. Inj 1% 2-Chloroprocaine has shorter onset and duration of action. This property makes it an ideal agent for day care surgeries.
