Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Based on the fact that arterial vasodilation can be advantageous for endovascular catheterization and that an increase in body temperature can cause vasodilation by activating the cholinergic active vasodilator system, this study was planned to observe whether there was a significant change in the diameter of artery through ultrasound and to confirm the effectiveness of heating in the traditional palpation technique and the US-guided technique after local warming of the insertion site of arterial catheter in adult patients undergoing cardiac surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Arterial cannulation is one of the important clinical techniques commonly used for real-time monitoring of blood pressure changes or when repeated blood tests are required. However, complications such as bleeding, hematoma, and vascular occlusion may occur if the operator has little or no experience in the procedure, or if arterial cannulation is not easy due to the patient's underlying disease and systemic factors. This situation prolongs the anesthesia induction time and may cause great harm to the patient in cases with a high bleeding tendency, such as in cardiac surgery. Various studies have reported various arterial cannulation techniques so far, and there have been many advances in arterial cannulation techniques due to the general use of ultrasound (hereafter US). However, there is still a risk of complications due to inexperience in the use of US or poor vascular status of the patient.
