One-Lung Ventilation

Le résumé fourni par la source

Abstract One-lung ventilation is required in a variety of thoracic, cardiac, gastrointestinal, and neurological spine surgeries. It is important to be aware of the relative and absolute indications for lung isolation, and it is prudent to individualize the technique to the patient and surgery. Successfully initiating and maintaining one-lung isolation can be accomplished through a variety of techniques, all of which require nuanced procedural skill and insightful troubleshooting. Knowledge of the tracheal-bronchial anatomy and a sound understanding of ventilation and perfusion concepts, as well as a methodical approach to troubleshooting, are required when faced with challenging clinical circumstances. Common problems include difficulties with placement of double-lumen tubes or endobronchial blocking devices with or without the added challenges of a difficult airway. Achieving and maintaining adequate functional placement of the selected device requires a certain knowledge of the tracheal-bronchial anatomy and its variations. During one-lung ventilation, hypoxemia (usually defined as desaturation with SpO2 values of less than 90% and/or PaO2 values of less than 60 mmHg), hypercarbia, and hemodynamic instability frequently require swift intervention to ensure optimal care.
