COMPARISON OF INTERSCALENE BRACHIAL PLEXUS BLOCK AND COMBINATION OF INTERSCALENE BRACHIAL PLEXUS BLOCK AND SUPRASCAPULAR NERVE BLOCK FOR ANAESTHESIA FOR SHOULDER SURGERIES

Objective- To compare analgesia, degree of motor block and hemodynamic effects of interscalene block with a combination of interscalene block
and suprascapular nerve block employed for anaesthesia for shoulder surgeries.
Methods- 46 patients of ASA grade I or II posted for shoulder surgery were divided into two groups of 23 patients each. Group IS received 15 ml
local anaesthetic mixture for interscalene brachial plexus block whereas group ISSB received suprascapular nerve block with 5 ml local anaesthetic
mixture in addition to interscalene brachial plexus block with 15 ml of similar mixture of local anaesthetic. Heart rate (HR), Systolic Blood
Pressure (SBP), Diastolic Blood Pressure (DBP), degree of analgesia and degree of motor blockade were assessed intraoperatively. General
anaesthesia was administered in the event of inadequate blockade. Any adverse events were documented.
Results- A combination of interscalene block and suprascapular nerve block was superior to interscalene block alone in terms of degree and
duration of analgesia as well as degree of motor blockade for shoulder surgeries without any signicant hemodynamic effects in either of the
groups.
Conclusion- Acombination of interscalene brachial plexus block and suprascapular nerve block is superior to isolated interscalene brachial plexus
block for anaesthesia for shoulder surgeries
