Does Radial Artery Cannulation Affect the Perfusion Index(PI) of the Hand in Liver Transplant Operations?

Study Overview
=================
Brief Summary
-----------------
radial artery cannulation is performed by an experienced person, non-invasive blood pressure measurement will be made at 3 stages of the operation (dissection, anhepatic, neohepatic) and the effects of radial artery cannulation on the perfusion index will be evaluated by recording the correlation between radial artery and invasive measurements and the perfusion indexes of both hands simultaneously with Masimo.

Detailed Description
-----------------
Arterial lines placement is for real-time monitoring of blood pressures and arterial blood sampling in critically ill patients or those undergoing complex procedures and surgeries. Routine monitoring will be performed after the patients are taken to the operating room. Before bilateral radial artery cannulation, allen test will be performed and entrance perfusion indexes will be checked. After radial artery cannulation is performed by an experienced person, non-invasive blood pressure measurement will be made at 3 stages of the operation (dissection, anhepatic, neohepatic) and the effects of radial artery cannulation on the perfusion index will be evaluated by recording the correlation between radial artery and invasive measurements and the perfusion indexes of both hands simultaneously with Masimo.
