Is Pericapsular Nerve Group Block Better Than Interscalene Nerve Block Regarding Effect on Hand Movement in Shoulder Scope Surgeries?

The goal of this clinical trial is to learn if pericapsular nerve group block (PENG) in shoulder scope surgery provides adequate analgesia with less affection of muscle power compared to interscalene block. The main questions it aims to answer are:

Does PENG block provide analgesia similar to interscalene block? Does PENG block have less or no effect on muscle power compared to interscalene block? Researchers will compare PENG block with interscalene block

Participants will:

Receive either PENG or interscalene block before shoulder scope surgery Be evaluated for their motor power after receiving the block and after the surgery Be evaluated for pain after the surgery

Treatment and study plan

pericapsular nerve group (PENG) block

Procedure

Injection of local anesthetic between deltoid muscle and subcapsularis tendon

Interscalene nerve block

Procedure

Injection of local anesthetic between anterior and middle scalene muscles around the roots of brachial plexus

Primary outcomes

  1. Time for full recovery of hand motor power

    Time frame: Starting from block activation until the achieves preoperative grip strength ( 24 hours)

    Time from start of block activation till time of achieving grip strength similar to patient's baseline

Secondary outcomes

  1. Hand grip power after surgery

    Time frame: 2,4,6,12,24 hours

    The measured hand grip power using a digital dynamometer

  2. Visual analogue scale assessment

    Time frame: 2,4,6,12 hours

    Assessing postoperative pain, scale from 0 to 10 where 0 is no pain and 10 is worst pain

  3. Time to first analgesia request

    Time frame: 24 hours

    Time from end of the surgery till the participant asks for additional analgesia

  4. Patient satisfaction score

    Time frame: 24 hours

    Assessing the participant satisfaction after the postoperative period regarding overall experience with the block given on a scale of 1 to 5, where 1 is the least satisfaction and 5 is the greatest.
