Official title
Predictive Value of Perioperative Lung Ultrasound Score for Early Postoperative Oxygen Requirement and Pulmonary Complications in Patients Undergoing Major Non-Thoracic Surgery
Overview
This prospective observational cohort study aims to evaluate the predictive value of perioperative lung ultrasound (LUS) score in determining early postoperative oxygen requirement and pulmonary complications in patients undergoing major non-thoracic surgery. Postoperative pulmonary complications remain a significant cause of morbidity and mortality in surgical patients. Lung ultrasound is a non-invasive, bedside imaging modality that allows real-time assessment of lung aeration and pathology. This study will investigate the association between perioperative LUS score and early postoperative respiratory outcomes, including oxygen requirement and pulmonary complications.
Detailed description
Postoperative pulmonary complications are among the most common causes of postoperative morbidity and prolonged hospital stay following major surgery. Early identification of patients at risk is crucial for timely intervention and improved outcomes. Lung ultrasound (LUS) has emerged as a reliable, non-invasive, and bedside tool for evaluating lung aeration and detecting pulmonary abnormalities such as atelectasis, interstitial syndrome, and pleural effusion.
This prospective observational cohort study is designed to assess the predictive value of perioperative lung ultrasound score in patients undergoing major non-thoracic surgery. A total of 97 patients aged between 18 and 65 years will be included. Lung ultrasound examinations will be performed perioperatively, and LUS scores will be calculated based on standardized protocols.
The primary objective of this study is to evaluate the relationship between perioperative LUS score and early postoperative oxygen requirement. Secondary objectives include assessing the association between LUS score and the incidence of postoperative pulmonary complications, need for intensive care unit admission, and length of hospital stay.
By identifying the predictive role of lung ultrasound scoring, this study aims to contribute to improved perioperative risk stratification and support the use of lung ultrasound as a practical tool in routine anesthetic and surgical care.
Primary outcome measures
- Early Postoperative Oxygen Requirement [Time frame: Within the first 24 hours after surgery]
Secondary outcome measures (6)
- Postoperative Pulmonary Complications [Time frame: Within 7 days after surgery]
- Correlation Between LUS Score and Hypoxemia [Time frame: Within 24 hours after surgery]
- Number of participants requiring ICU admission [Time frame: Within 7 days after surgery]
- Length of Hospital Stay [Time frame: From surgery until hospital discharge (up to 30 days)]
- Duration of Postoperative Oxygen Therapy [Time frame: Within the first 24 hours after surgery]
- Number of participants requiring high-flow nasal oxygen or noninvasive ventilation [Time frame: Within 7 days after surgery]
