Diaphragm Dysfunction and Respiratory Complications in the Perioperative Setting Can Diaphragm Ultrasound Aid Prediction?

What this Trial Is About

This research aims to find out if using diaphragm ultrasound to measure diaphragm thickening fraction, excursion, and density before and after major abdominal, pelvic, or vascular surgery can predict respiratory complications during the 30 days after surgery. Respiratory complications include pneumonia, desaturation, need for intubation, and other events. The study focuses on adults scheduled for elective or acute surgery and seeks to address the impact of diaphragm dysfunction on postoperative outcomes and recovery. Participants will undergo diaphragm ultrasound exams before surgery and multiple times after surgery in the postoperative ward. This non-invasive and painless imaging uses ultrasound transducers to measure diaphragm movement, thickness, and density. Researchers will also monitor vital signs, oxygen levels, medication, anesthesia details, and surgery data. The study consists of two parts: one with elective surgery patients and one with acute surgery patients, each observed closely for respiratory complications up to 30 days post-surgery. Throughout the study, participants will have their diaphragm assessed using ultrasound at set times before and after surgery, with vital parameters recorded in detail. Researchers will collect data on respiratory complications from medical records and correlate these with the ultrasound findings to evaluate diaphragm function's predictive value. Data security measures will protect ultrasound images and patient information. The study will analyze outcomes like pneumonia occurrence, respiratory insufficiency, and oxygen desaturation to better understand and prevent postoperative respiratory issues.
