초록	Introduction: Patients with end-stage renal disease (ESRD) can be hemodynamically unstable because of frequent changes in peripheral resistance and blood volume during kidney transplant surgery. Cardiac output (CO) is a key variable when describing and treating the cardiovascular system. Thermodilution via a pulmonary artery catheter is the most frequently used method, but it lacks accuracy. Non-invasive cardiac output monitoring (NICOM) measures CO based on chest bioreactance. Validated data of NICOM in patients with kidney transplant surgery are lacking. So we had non-invasive cardiac output monitoring during anesthesia for renal transplant surgery. Methods: CO values using NICOM were recorded during anesthesia in patients with renal transplant surgery due to ESRD. Correlation analysis were performed with variables measured 59 times from 20 subject. Results: Stroke volume (SV) had strong negative correlation with total peripheral resistance (TPR) (R=-0.81, p=0.00, Fig. 1). But SV had poor correlation with mean arterial pressure (MAP) (R=-0.26, p=0.05). And TPR had fair correlation with MAP (R=0.36, p=0.01). Fig.1.The scatter diagram between stroke volume and total peripheral resistance measured by NICOM in patients with kidney transplant surgery. Conclusions: Stroke volume and total peripheral resistance measured by NICOM showed a strong correlation in patients with renal transplant surgery. Additional studies in larger patient populations may be warranted for further validation.
