Comparison of Sedated and Unsedated PEG in Elderly ASA IV Patients

7. september 2026 opdateret af: Hilmi Bozkurt, Mersin University

Comparison Of Safety And Clinical Outcomes Of Sedated And Unsedated Percutaneous Endoscopic Gastrostomy Procedures İn ASA IV Elderly Patients: A Prospective Observational Cohort Study.

This prospective observational cohort study aims to compare the safety and clinical outcomes of sedated and unsedated percutaneous endoscopic gastrostomy procedures in elderly patients classified as ASA IV. The primary outcome is the development of cardiopulmonary complications within the first 24 hours after the procedure. Secondary outcomes include technical success, procedure duration, early procedure-related complications, length of hospital stay, intensive care requirement, 30-day mortality, and 30-day readmission.

Detaljeret beskrivelse

Percutaneous endoscopic gastrostomy is commonly used to provide long-term enteral nutrition in patients who are unable to maintain adequate oral intake. Elderly patients with severe systemic disease and high anesthetic risk may be vulnerable to sedation-related cardiopulmonary adverse events. In some clinical settings, PEG can be performed using topical pharyngeal anesthesia and local anesthesia without systemic sedation.

This study will prospectively include elderly ASA IV patients undergoing PEG placement in routine clinical practice. Patients will be categorized into two cohorts according to the sedation strategy used during the procedure: unsedated PEG and sedated PEG. The sedation strategy will not be assigned by the investigators and will be determined according to routine clinical assessment, patient condition, and anesthesiology evaluation when required.

The study will compare cardiopulmonary complications within 24 hours, technical success, procedure-related complications, and 30-day clinical outcomes between the two cohorts.

Foranstaltningsbeskrivelse
Tidsramme
Incidence of cardiopulmonary complications within 24 hours after PEG placement
Tidsramme: Within 24 hours after PEG placement
Cardiopulmonary complications will be assessed as a composite outcome including the occurrence of at least one of the following events within the first 24 hours after PEG placement: hypoxemia defined as SpO₂ <90%, hypotension defined as mean arterial pressure <65 mmHg, bradycardia defined as heart rate <50 beats/min, aspiration, need for endotracheal intubation, or intensive care unit admission/transfer.
Within 24 hours after PEG placement
