Investigation Into the Effect of 0.25% Bupivacaine for Interscalene Peripheral Nerve Block vs 0.125% Bupivacaine on Pulmonary Function
In Brief
A clinical study evaluating interscalene nerve block with 0.25% bupivacaine and interscalene block with 0.125% bupivacaine for Diaphragm Paralysis. Completed, enrolled 30 participants across 1 site.
Detailed Summary
Peripheral nerve blocks are used to provide post-operative pain relief. Nerve blocks in the neck, in the interscalene area, provide pain relief after shoulder surgery but can cause temporary weakness or paralysis of the diaphragm. The investigators hypothesized that a lower concentration of bupivacaine would cause less weakness of the diaphragm but still provide good pain relief. Lung function and pain control was studied after interscalene peripheral nerve block with 20 milliliters of 0.25% bupivacaine or 0.125% bupivacaine.
