Suprascapular and Axillary Versus Interscalene Blocks Regarding Phrenic Affection in Shoulder Surgeries
Sponsor: Ain Shams University
Summary
This study is aims to compare between combined suprascapular and axillary nerve blocks versus interscalene nerve block regarding phrenic nerve affection assessed by ultrasound guided diaphragmatic excursion in shoulder arthroscopy surgeries.

Interventions
Suprascapular nerve block and Axillary nerve block
A linear ultrasound probe will be placed in a sagittal plane at the superior medial border of the scapula. The probe will be moved laterally and then placed parallel to the scapular spine. when the needle tip contacts the bone just medial to the spinoglenoid notch and after confirmation of absence of vascular structure by color Doppler, 10 ml of 0.5% bupivacaine will be injected with aspiration every 3 ml to avoid intravascular injection and the spread of the local anaesthetic
Interscalene Nerve Block
The ultrasound probe will be placed in the supraclavicular fossa in a transverse orientation, aimed caudad into the thoracic cavity, to visualize the brachial plexus near the subclavian artery. Once identified, the plexus will be followed cephalad where it is found within the brachial plexus fascial sheath in the interscalene groove.
