Summary

It is a prospective observational study of a cohort of patients who underwent brachial plexus blockage above the clavicle, and in which diaphragmatic function is observed in both hemidiaphragms by ultrasound (using Diaphragm Thickening Fraction), which allows to obtain the real incidence of Hemidiaphragm palsy in these patients, and estimate the perioperative evolution of both hemidiaphragms.

Hemidiaphragm palsy after brachial plexus block above the clavicle (BPBAC) is frequent, but few patients develop postoperative pulmonary complications (PPC). Little attention has been paid to the contralateral hemidiaphragm as part of the global diaphragmatic function. After BPBAC, global diaphragm function reduces due to ipsilateral hemidiaphragm reduction, but less than expected due to the increase in the contralateral hemidiaphragm function. As a part of the diaphragm function, the contralateral hemidiaphragm function plays a relevant role in the appearance of PPC.
