Eligibility

Inclusion criteria

Inclusion criteria: ASA Grade I, II, III Patients undergoing elective upper limb surgeries from below mid-arm. Surgeries in supine position. BMI: 18.5 â?? 24.9

Exclusion criteria

Exclusion criteria: Patient refusal. Contraindications to regional nerve block: -Cellulitis/ infection at the local site. -Coagulopathy. -Allergy to local anaesthetic agents.

Design outcomes

Primary

Measure	Time frame
To compare success rateTimepoint: The block is taken as successful when there is complete sensory blockade and surgery completed only under regional block. If one nerve is spared, a rescue block will be given. If more than one nerve is spared, General anaesthesia will be administered. These will be considered as failure of the block.	—

Secondary

Measure	Time frame
Time taken for onset of sensory and motor blockadeTimepoint: 0 min 15 min 30 min;Time taken to perform the blockTimepoint: The time interval between the first needle insertion and injection of the drug will be taken as the procedure time.;Number of attemptsTimepoint: The number of skin puncture made to perform the block will be noted. The maximum number will be limited to three after which it will be abandoned. This will be taken as failure and proceeded to alternative methods of anaesthesia.;Incidence of complications such as: Vascular injections, pneumothorax, phrenic nerve palsy and Hornerâ??s syndromeTimepoint: Number of patients having complications such as vascular injections, pneumothorax, nerve injury, phrenic nerve palsy, Hornerâ??s syndrome	—
