A prospective randomised low dose finding study of preservative free 1% cloroprocaine in spinal anesthesia for perineal surgeries

Ambulatory surgery has become popular in this era which has resulted in the advent of newer short acting anaesthetic drugs to suit early ambulation of post operative patients and discharge and early resumption of daily activities. This in turn reduces cost of care, increased availability of beds for sick patients, lower risk of resistant bacterial strain transmission and faster return to work and social activities., This study was aimed to find out the effective low dose of 1% chloroprocaine for lower limb ambulatory surgeries performed as day care procedures. 93 consented patients were randomized to three groups of 31 each to receive 20 mg, 25 mg and 30mg of 1%chloroprocineintrathecally. Sensory and motor block was assessed.: The collected data was analysed using IBM.SPSS statistics23.0 Version.The demographic data in all three groups were comparable. The onset of motor blockade was profound in patients receiving 30 mg of chloroprocaine compared to 20 or 25 mg. The blook persisted for longer duration with delayed voiding of urine, delay in unassisted ambulation inpatients receiving 30 mg of 1% chloroprocaine.
