Study population: The study population consists of patients aged 65 years and older who are scheduled to undergo elective major abdominal surgery under general anesthesia. Eligible participants will be managed in a tertiary care hospital and will be allocated to either a fascial plane block group or a control group receiving standard perioperative analgesia. The study aims to evaluate postoperative outcomes in an elderly surgical population with comparable baseline characteristics.

- Age 65 years or older
- Scheduled for elective major abdominal surgery (e.g., colorectal, hepatobiliary, pancreatic, or gastric surgery)
- ASA physical status II-III
- Ability to provide written informed consent

About this study
Official title: The Effect of Ultrasound-Guided Fascial Plane Blocks on Postoperative Pulmonary Complications in Patients Undergoing Major Abdominal Surgery: A Prospective Observational Study
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.
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Fascial Plane Block Group | Patients undergoing elective major abdominal surgery who receive an ultrasound-guided fascial plane block at the end of surgery as part of routine clinical practice for postoperative analgesia. The decision to perform the block is made by the responsible anesthesia team and is not influenced by the study protocol. | |
| Control Group | Patients undergoing elective major abdominal surgery who do not receive an ultrasound-guided fascial plane block and are managed with other routine postoperative analgesic methods, including epidural analgesia, intravenous patient-controlled analgesia, or oral analgesics, according to standard clinical practice. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of postoperative pulmonary complications (PPCs)
Postoperative pulmonary complications will be defined and recorded according to the European Perioperative Clinical Outcome (EPCO) criteria.
Measured: Within the first 7 postoperative days
