Anesthetic Management for Whole Lung Lavage in Patients with Pulmonary Alveolar Proteinosis

Anesthetic Challenges During Whole Lung Lavage: A Case Report

Pulmonary alveolar proteinosis is an uncommon lung disease characterized by the accumulation of surfactant in the lungs. Treatment is done by whole lung lavage. One-lung ventilation in diseased lungs is a challenge to anesthesiologists due to the rapid desaturation and hemodynamic fluctuations encountered during the procedure. A 24-year-old female, a known patient of pulmonary alveolar proteinosis, who had undergone previous lung lavage presented with a dry cough and shortness of breath. Our management of the case included complete lung isolation with a double-lumen tube (DLT), one-lung ventilation, and an appropriate hemodynamic management strategy during the procedure.

Whole-Lung Lavage-a Narrative Review of Anesthetic Management

Pulmonary alveolar proteinosis is a rare disease characterized by progressive accumulation of lipoprotein material in the alveoli as a result of a dysfunction in surfactant clearance. The whole-lung lavage procedure is considered the current standard of care and consists of the sequential lavage of both lungs for mechanical removal of residual material in the alveoli. However, a lack of standardization has resulted in different procedural techniques among institutions. Even though whole-lung lavage is considered to be a safe procedure, unforeseen complications might occur, and proper knowledge of physiologic implications may allow clinicians to establish the appropriate therapy. This review provides an insight into the underlying physiology of the disease, the technical details of the procedure from an anesthesiologist's perspective, and discussion of potential intraoperative complications.
