Pressure Sensing Sheath Blood Pressure Monitoring Compared to Traditional Methods in Interventional Procedures
Recruiting now
Conditions studied: Blood Pressure Monitoring, Neuroendovascular Procedures
In brief
This observational study aims to evaluate the accuracy and safety of pressure sensing sheath blood pressure monitoring compared to traditional invasive and non-invasive blood pressure monitoring methods during neuroendovascular interventional procedures. The study will enroll 50 adult patients undergoing elective neuroendovascular procedures requiring general anesthesia and continuous invasive blood pressure monitoring. Blood pressure will be simultaneously measured using three methods: (1) pressure sensing sheath, (2) radial arterial line, and (3) non-invasive cuff monitoring. The primary outcome is the accuracy of blood pressure measurements from the pressure sensing sheath compared to radial arterial line measurements. Secondary outcomes include the incidence of access site complications, procedure duration, patient comfort scores, and cost-effectiveness analysis. This prospective, single-center study will be conducted at Shanghai Fourth People's Hospital Affiliated to Tongji University from August 2025 to May 2027.
