Nov 27, 2023
auto_awesome
Dr. Rehan Quadri, practicing interventional radiologist at UT Southwestern in Dallas, Texas, discusses the impact of a new arterial sheath technology that enables real-time blood pressure monitoring in trauma, GI bleeds, stroke, and other emergent arterial interventions. They break down the specs of the sheath and its accuracy, cost, and value. They also discuss advancements in the technology, including improved warmup times and a radial-specific sheath.
The EndoPhys Pressure Sense Arterial Sheath enables real-time blood pressure monitoring during emergent cases such as trauma and GI bleeds, resulting in improved outcomes and blood pressure control.
The EndoPhys sheath is a disposable arterial access sheath that offers accurate and frequent blood pressure measurements, eliminating the need for separate arterial lines and providing valuable pressure gradients during procedures like visceral artery stenting.

Benefits and Usage of Intra-Arterial Blood Pressure Monitoring
In this podcast episode, the speaker discusses the benefits and usage of intra-arterial blood pressure monitoring. Initially developed for stroke patients, this technology allows for immediate and continuous monitoring of blood pressure during emergent cases such as trauma and GI bleeds, where accurate and minute-to-minute feedback is crucial. The speaker shares a case where the sheath was used in a trauma patient, resulting in improved blood pressure control and a more stable outcome. The sheath is easy to use, requiring minimal changes to the regular sheath placement procedure. It eliminates the need for separate arterial lines and offers accurate and frequent blood pressure measurements, making it a valuable tool in interventional procedures.
Features and Functionality of the Endofiz Sheath
The Endofiz sheath is a disposable arterial access sheath that incorporates a microchip and pressure sensor for continuous blood pressure monitoring. It is available in different sizes and lengths, accommodating various access points such as the groin and radial arteries, with upcoming models specifically designed for radial access. The sheath is easy to place, requiring calibration outside the body before insertion. It provides immediate and stable access, enabling uninterrupted blood pressure monitoring during procedures. The pressure readings are highly accurate, collecting data every 250 to 500 times a second and providing smooth, continuous measurements.
Clinical Applications and Cost Considerations
The Endofiz sheath has shown great utility in trauma cases, GI bleeds, and emergent arterial interventions, where minute-to-minute monitoring is essential. It offers advantages over traditional arterial lines, providing more reliable and precise readings. The sheath can be used for monitoring visceral artery stenting, providing valuable pressure gradients during procedures. While the sheath is priced at around $800, the time saved and improved outcomes justify the cost. Integration with electronic medical records, like Epic, allows for seamless documentation and data analysis. Anesthesia teams have been supportive of using the sheath, recognizing its benefits and efficiency.
Future Developments and Conclusion
The Endofiz sheath is continuously evolving with the introduction of smaller sizes and variations to accommodate different anatomical sites. The company plans to release a radial access sheath, further expanding its applications in interventional procedures. The sheath holds promise for a wide range of clinical scenarios, offering accurate and continuous blood pressure monitoring without the need for additional invasive lines. Overall, the Endofiz sheath presents a valuable tool for interventionalists, providing real-time and reliable blood pressure measurements that enhance procedural safety and patient care.
In this episode, host Dr. Aaron Fritts interviews Dr. Rehan Quadri about the impact of intra-procedural arterial monitoring via sheath technology. Dr. Quadri is a practicing interventional radiologist at UT Southwestern in Dallas, Texas.
