Postoperative Pulmonary Complications in Elderly Patients Undergoing Major Abdominal Surgery

This study aims to identify the risk factors associated with postoperative pulmonary complications (PPCs) in patients aged 65 years and older who undergo major abdominal surgery.

The study is designed as a retrospective observational analysis using data from patient records.

Understanding these risk factors may help clinicians improve perioperative care and reduce the risk of respiratory problems after surgery in elderly patients.
