Abdominal Surgeries, Postoperative Pain Management, Postoperative Pulmonary Complications (PPCs)
Conditions
Brief summary
This prospective observational study aims to evaluate whether the use of ultrasound-guided fascial plane blocks is associated with a lower incidence of postoperative pulmonary complications in adult patients undergoing elective major abdominal surgery under general anesthesia. Patients will be observed in two groups based on routine clinical practice: those who receive an ultrasound-guided fascial plane block for postoperative analgesia and those managed with other standard analgesic methods. The choice of analgesic technique will be determined by the responsible anesthesia team and not influenced by the study. Postoperative pulmonary complications occurring within the first 7 days after surgery will be recorded using reopening the European Perioperative Clinical Outcome (EPCO) criteria. Secondary outcomes will include unplanned intensive care unit admission, length of hospital stay, and 30-day mortality. No additional procedures or interventions will be performed for research purposes.
