Diaphragm-sparing brachial plexus blocks: a focused review of current evidence and their role during the COVID-19 pandemic.
Abstract
Given that COVID-19 can severely impair lung function, regional anesthesia techniques avoiding phrenic nerve paralysis are relevant in the anesthetic management of suspected/confirmed COVID-19 patients requiring shoulder and clavicle surgical procedures. The objective of this review is to provide an overview of recently published studies examining ultrasound-guided diaphragm-sparing regional anesthesia techniques for the brachial plexus (BP) to favor their preferent use in patients at risk of respiratory function compromise.
