The aim of this study is to evaluate whether there is a difference in hemodynamic events requiring intervention between patients monitored with advanced hemodynamic monitoring using the MostCare system and those monitored with standard monitoring alone during propofol sedation for ERCP procedures.

ERCP is a widely used interventional procedure for the visualization and treatment of biliary and pancreatic duct disorders. Compared with surgery, it is less invasive and provides an effective therapeutic alternative. Although its diagnostic use has declined with the increasing availability of less invasive imaging modalities, ERCP is still frequently performed for therapeutic purposes such as relieving biliary or pancreatic obstruction, placing stents, and obtaining tissue samples. The need for ERCP is particularly increasing in elderly patients due to biliary stones and malignant obstruction. In this population, sepsis, hemodynamic fragility, and accompanying comorbidities make anesthesia and sedation management more challenging during the procedure. The primary goal of perioperative hemodynamic management is to maintain adequate organ perfusion and oxygen delivery. Although blood pressure is routinely monitored in clinical practice, parameters such as cardiac output, stroke volume, systemic vascular resistance, and afterload may provide a more comprehensive understanding of the mechanisms underlying hemodynamic status. A normal mean arterial pressure alone does not necessarily indicate adequate cardiac output or tissue perfusion. Therefore, some hemodynamic disturbances may remain undetected in patients assessed with standard monitoring alone. Advanced hemodynamic monitoring methods allow continuous assessment of parameters such as cardiac output, stroke volume, systemic vascular resistance, arterial elastance, and cardiac power output through arterial waveform analysis. The MostCare system, using PRAM technology, can obtain these data from the invasive arterial pressure waveform without requiring external calibration. By providing a more detailed evaluation of the causes of hemodynamic instability, it may facilitate more targeted and timely interventions. The aim of this study is to evaluate whether advanced hemodynamic monitoring with MostCare provides an advantage over standard monitoring alone in the detection and management of hemodynamic events requiring intervention in patients undergoing ERCP under propofol sedation. In addition, the study seeks to clarify the potential clinical contribution of advanced monitoring in interventional procedures performed under sedation.
