Ultrasound-guided technology for supraclavicular block in paediatric population over traditional techniques had a good success rate. But it still remained unclear whether triple injections(TI) was superior to single injection(SI).So, study had been carried out to compare success rate, onset time of block, procedure time of block, complications and conversion rate to General anesthesia in both groups. It was prospective, randomized, double blinded comparative study, conducted after obtaining approval from institutional ethical committee and written informed consent from patients’ attenders. Patients of age 6-12yrs, undergoing upper limb surgeries under Supraclavicular block with ASA-1 status were included in study. Patients with drug allergy or upper respiratory tract infections were excluded. Patients were randomly assigned into 2groups, Group SI and TI with 50 patients each. Combined success rate of the block was not significant in both TI and SI group (86% in SI vs 84% in TI,P=0.779).Onset time of block in TI group was faster(mean=9.98min) than SIgroup(12.84min).Performance time of block wassignificantlylonger in TI(mean=8.90min) than SI group(mean=5.10min). Conversion to General Anaesthesia due to block failure was minimal and not significant in either groups and no complications were seen in our study.
