Summary

This observational study investigates the relationship between the duration of single-lung ventilation (SLV) and the incidence of postoperative pulmonary complications (PPCs) such as pneumonia, pneumothorax, hemothorax, acute lung injury, and acute respiratory distress syndrome (ARDS) in adult patients undergoing thoracic surgery. A total of 134 patients aged 18-85 years, scheduled for thoracic surgery requiring SLV, will be monitored. Data including SLV duration, perioperative parameters, and postoperative pulmonary outcomes will be analyzed.

Conditions

• Postoperative Pulmonary Complications
• One Lung Ventilation
• Ards
• Postoperative Pulmonary Atelectasis

Interventions

Type	Name	Description
PROCEDURE	One-Lung ventilation	In this observational study, the naturally occurring duration of intraoperative single-lung ventilation (SLV) during thoracic surgery will be recorded. No intervention is applied or modified for research purposes. The exposure of interest is the total duration (in minutes) of SLV, which will be timed from initiation to termination during surgery. This variable will be analyzed in relation to postoperative pulmonary complications.
