Perioperative Diaphragm Dysfunction

Abstract

Diaphragm Dysfunction (DD) is a respiratory disorder with multiple causes. Although both unilateral and bilateral DD could ultimately lead to respiratory failure, the former is more common. Increasing research has recently delved into perioperative diaphragm protection. It has been established that DD promotes atelectasis development by affecting lung and chest wall mechanics. Diaphragm function must be specifically assessed for clinicians to optimally select an anesthetic approach, prepare for adequate monitoring, and implement the perioperative plan. Recent technological advancements, including dynamic MRI, ultrasound, and esophageal manometry, have critically aided disease diagnosis and management. In this context, it is noteworthy that therapeutic approaches for DD vary depending on its etiology and include various interventions, either noninvasive or invasive, aimed at promoting diaphragm recruitment. This review aims to unravel alternative anesthetic and operative strategies that minimize postoperative dysfunction by elucidating the identification of patients at a higher risk of DD and procedures that could cause postoperative DD, facilitating the recognition and avoidance of anesthetic and surgical interventions likely to impair diaphragmatic function.

Bi-parametric MRI of the Diaphragm Using Dynamic and Static Images: The Initial Experience

“…In the context of respiratory disorders, diaphragmatic dysfunction is not limited to paralysis. Conditions like chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF) also involve significant diaphragmatic involvement [ 5 ]. Additionally, ultrasound evaluations in IPF patients have revealed significant differences in diaphragmatic function compared to healthy controls, highlighting the importance of advanced imaging techniques in managing various pulmonary diseases [ 6 ].…”
