Design outcomes

Primary

Measure	Time frame
To compare the analgesic efficacy in terms of onset of sensory blockade of ultrasound guided Intercostobrachial Nerve Block by three different approaches - distal approach versus proximal approach versus supra-axillary approach for patients undergoing proximal humerus surgeries done via delto-pectoral approach.Timepoint: The Sensory block onset will be assessed every 2 minutes for 15 minutes via pinprick testing over the anteromedial and posteromedial upper arm.	—

Secondary

Measure	Time frame
To assess the ease of technique in terms of duration of procedureTimepoint: Duration of the procedure will be recorded combining Landmark identification time (USG localization of target area) and Block execution time (from needle insertion to withdrawal after injecting the drug).;To assess the incidence of ICBN block failures.Timepoint: No sensory loss after 15 min after giving block will be noted;To assess analgesic efficacy post operatively using Visual analogue scale score.Timepoint: post operatively at at 0,2,4,6,12, and 24 hours;To assess incidence of complications like hematoma, nerve injury and pneumothorax.Timepoint: while administering the nerve block	—
