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.
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
Refusal or inability to provide informed consent
Known allergy or contraindication to local anesthetics
Coagulopathy or ongoing anticoagulant therapy contraindicating regional anesthesia
Infection at the site of planned block
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.
