Comparison of the Central Venous Pressures Measured From the Peripherally Inserted Antecubital Central Catheters and the Internal Jugular Vein Central Catheters in Liver Transplantation Recipients

Brief Summary

Detailed Description

According to the protocol of LT in our hospital, a PICC is concomitantly inserted with the pulmonary artery catheter (PAC) and 9-Fr advanced venous access (AVA) catheter for the LT recipient at anesthetic induction. PAC and AVA catheter are usually removed on the second postoperative day, and instead the PICC is used for the postoperative infusion of prostaglandin E1 which is very irritable to small peripheral vein. So we fortunately had chance to measure the CVPs from both CICC and PICC simultaneously in the same patients. Methods: We measured the CVPs from the CICC and the PICC simultaneously during each main surgical period of adult liver transplantation (preanhepatic, anhepatic, reperfusion, and neo-hepatic period). Data are presented as means ± standard deviation. Statistical analysis was performed using simple linear regression analysis to observe whether changes in the PICCP were paralleled by simultaneous changes in the CICCP. Bland-Altman analysis was used to determine the degree of agreement between the two devices. Analysis of variance was performed to study whether there were changes in the CVP agreement profiles in regard to the different time periods of LT. Differences were regarded as being statistically significant when p values were less than 0.05. (This observational study has been completed already.)
