Reperfusion Injury After Pulmonary Thromboendarterektomy
Conditions
Keywords
Chronic thromboembolic pulmonary hypertension, PEEP, reperfusion injury
Brief summary
Investigation of the effect of intraoperative lung protection high PEEP maneuver on ischemic reperfusion injury in patients undergoing pulmonary endarterectomy.
Detailed description
Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare disease characterized by progression of thromboembolism obstructing pulmonary arteries as an organized tissue. Pulmonary thromboendarterectomy (PTE) is a treatment option for chronic thromboembolic pulmonary disease. However, PTE is associated with specific postoperative complications, such as pulmonary edema and right ventricular failure due to reperfusion injury, with a significant mortality rate of 7% to 24%. Some strategies have been proposed to reduce lung injury after PTE, such as rectification maneuvers and high PEEP. The aim of this study was to investigate the effect of intraoperative lung protection high PEEP maneuver in patients undergoing pulmonary endarterectomy for ischemic reperfusion injury.
Interventions
performing 35 cm/H2O PEEP and 2-3 ml/kg tidal volume
performing 6 cm/H2O PEEP and 6-8 ml/kg tidal volume
