Objective To evaluate the relationship between different levels of central venous pres-sure (CVP) and blood loss during pediatric living donor liver transplantation (LDLT). Methods Pediat-ric patients underwent LDLT in Renji Hospital from 2006 to August 10, 2016 were retrospectively reviewed. The patients were divided into 2 groups according to the different CVP levels before peritoneum closure:central venous pressure<10 mmHg group ( group L) and CVP≥10 mmHg group ( group H) . The primary outcome measure was intraoperative blood loss. The secondary outcome measures were duration of mechani-cal ventilation in intensive care unit (ICU), duration of ICU stay, length of postoperative hospital stay, intraoperative blood loss, intraoperative blood transfusion, intraoperative volume of liquid infused, opera-tion time and anesthesia time. Results A total of 442 pediatric patients were enrolled in this study, with 209 cases in group L and 233 cases in group H. Compared with group H, the intraoperative blood loss was significantly decreased, the anesthesia time, operation time and length of postoperative hospital stay were shortened ( P<0. 05) , and no significant change was found in intraoperative blood transfusion, intraopera-tive volume of liquid infused, duration of mechanical ventilation in ICU or duration of ICU stay in group L ( P>0. 05) . Conclusion Maintaining intraoperative CVP<10 mmHg can markedly reduce the blood loss during LDLT and is helpful for postoperative recovery in pediatric patients.
