简要总结
Nowadays, intraarterial catheterization is frequently used as an invasive method for intraoperative blood pressure monitoring and control.The radial artery is frequently used in this procedure and the cannula should be flushed with 2-3 ml of heparinized fluid intermittently to prevent occlusion. During the operation, the ambient temperature is approximately 22-24 C and the patient temperature can be 34-36 C. Since the flushing fluids are also in the environment, they are 22-24 C. The aim of this study is to determine whether the fluids at room temperature cause vasoconstriction in the vessel and cause a change in blood pressure arterial values.
