Lung Ultrasound Score on Postoperative Day 1 Is Predictive of the Occurrence of Pulmonary Complications after Major Abdominal Surgery: A Multicenter Prospective Observational Study
Authors' conclusion
An elevated lung ultrasound score on postoperative day 1 is associated with the occurrence of pulmonary complications within the first 10 days after major abdominal surgery.
Study context
- Population
- Patients scheduled for major abdominal surgery
- Participants
- 149 patients
- Exposure
- PPCs vs no PPCs before day 10; lung ultrasound score cutoffs >12 and >17
- Outcome
- Performance of lung ultrasound score on POD 1 in predicting PPCs
- Follow-up
- Before POD 10
