Usefulness of the ClearSight System in Monitoring Patients with End-Stage Renal Stage: Two Case Reports

Since blood pressure tends to be unstable during surgery, an arterial catheter is often inserted to monitor arterial pressure continuously during general anesthesia. However, there are some situations wherein arterial cannulation is not allowed. ClearSight System enables noninvasive continuous monitoring of arterial pressure and derives variables via a single finger cuff without arterial cannulation. We describe two cases of end-stage renal disease patients who were hemodynamically unstable during surgery. In these cases, rapid and appropriate management was possible using the ClearSight System in a situation where the arterial puncture was difficult.
