Propofol Clinical Trial
Official title:
Comparison of the Effect od Ketofol and Propofol on Intracranial Pressure Evaluated by Sonographic Optic Nerve Sheath Diameter Measurements in the Endoscopic Retrograde Cholangiopancreatography Procedures
Aim: To compare the effect of procedural anesthesia management with ketofol and propofol on the sonographic optic nerve sheath diameter in the endoscopic retrograde cholangiopancreatography (ERCP) procedures.
Adequate visualization of the gastrointestinal mucosa during endoscopic retrograde cholangiopancreatography (ERCP) requires distention of the intestinal lumen by gas insufflation. High intraluminal pressures can increase intraabdominal pressure, leading to an increase in intracranial pressure. Ultrasonographic measurement of the optic nerve sheath diameter is a simple, non-invasive, and reliable technique for assessing intracranial pressure. Propofol, a sedative-hypnotic agent with rapid onset and short duration of action, is often used.Theoretically, the combination of ketamine and propofol may maintain sedation efficacy while reducing cardiovascular side effects through dose reduction and due to its synergistic effects. The aim of this study is to demonstrate whether our anesthesia management has an effect on ICP change by measurement of optic nerve sheath diameter, predicting that insufflation performed for imaging during the ERCP procedure increase intraabdominal pressure, and frequently observed situations such as insufficient sedation, prone position, coughing and Valsalva during the procedure increase intracranial pressure (ICP). ;
