Case scenario: Management of intraoperative hypoxemia during one-lung ventilation.
H YPOXEMIA that may reasonably be defined by an arterial hemoglobin oxygen saturation of less than 90% occurs in 5–10% of patients during one-lung ventilation (OLV). The physiopathology of hypoxemia is complex, and the management of intraoperative hypoxemia during OLV remains a challenge for anesthesiologists. In life-threatening hypoxemia, correct oxygenation should be restored rapidly. This m...
متن کاملPharmacological Treatment of Hypoxemia during One-lung Ventilation.
To the Editor: We read with great interest the Case Scenario on hypoxemia during one-lung ventilation (OLV) reported by Rozé et al., and we would like to add some comments on pharmacological treatment. First, the title of the section, “Pharmacological treatment to limit hypoxic pulmonary vasoconstriction,” could, in our opinion, lead to confusion. Almitrine does not limit hypoxic pulmonary vaso...
متن کاملApproaches to hypoxemia during single-lung ventilation.
Modern techniques to isolate the lungs, coupled with accurate continuous non-invasive monitoring, have made single-lung ventilation safe and easy to perform. Most patients maintain an adequate arterial oxygen tension during single-lung ventilation. In order to maximize oxygenation, efforts are directed towards optimizing perfusion and ventilation to the ventilated lung or increasing the oxygen ...
متن کاملIndependent Lung Ventilation and One Lung Ventilation
The application of the independent lung ventilation (ILV) in adults has been described by Carlon and co-workers in 1978 and subsequently by other investigators. In 1983 Hedenstierna and coworkers using a bilumen tube suitable for prolonged intubation, and two Servo Ventilator 900 B (Siemens) adapted for synchronization, treated a wide range of clinical conditions. Following this experience, the...
متن کاملPhenylephrine to Treat Hypoxemia during One-Lung Ventilation in a Pediatric Patient
To improve surgical visualization and facilitate the procedure, one-lung ventilation (OLV) is frequently used during thoracic surgery. Although generally well tolerated, the ventilation-perfusion inequality induced by OLV may lead to a decrease in oxygenation and, at times, hypoxemia. Effective treatment algorithms and strategies are necessary for the treatment of hypoxemia during OLV to ensure...
