Summary

To compare ISB vs anterior and posterior approaches of suprascapular block in terms of lung function and analgesia

Detailed description

Interscalene block (ISB) is commonly used to provide pain control for shoulder surgeries. However, it is associated with several side effects, in particular, a high incidence of phrenic nerve blockade. The suprascapular nerve block (SSB) has been proposed as an alternative to the ISB as it has a lower likelihood of causing phrenic nerve blockade. There are 2 commonly used approaches for the suprascapular nerve block, anterior and posterior. The anterior approach may still result in some degree of impairment of lung function. The primary aim is to assess the pulmonary function after performance of ISB, aSSB and pSSB. Secondary outcomes are analgesic effects and incidence of adverse effects of these blocks.
