摘要 BACKGROUND Acute lung injury(ALI)after liver transplantation(LT)may lead to acute respiratory distress syndrome,which is associated with adverse postoperative outcomes,such as prolonged hospital stay,high morbidity,and mortality.Therefore,it is vital to maintain hemodynamic stability and optimize fluid management.However,few studies have reported cardiac output-guided(CO-G)management in pediatric LT.AIM To investigate the effect of CO-G hemodynamic management on early postoperative ALI and hemodynamic stability during pediatric living donor LT.METHODS A total of 130 pediatric patients scheduled for elective living donor LT were enrolled as study participants and were assigned to the control group(65 cases)and CO-G group(65 cases).In the CO-G group,CO was considered the target for hemodynamic management.In the control group,hemodynamic management was based on usual perioperative care guided by central venous pressure,continuous invasive arterial pressure,urinary volume,etc.The primary outcome was early postoperative ALI.Secondary outcomes included other early postoperative pulmonary complications,readmission to the intense care unit(ICU)for pulmonary complications,ICU stay,hospital stay,and in-hospital mortality.RESULTS The incidence of early postoperative ALI was 27.7%in the CO-G group,which was significantly lower than that in the control group(44.6%)(P<0.05).During the surgery,the incidence of postreperfusion syndrome was lower in the CO-G group(P<0.05).The level of intraoperative positive fluid transfusions was lower and the rate of dobutamine use before portal vein opening was higher,while the usage and dosage of epinephrine during portal vein opening and vasoactive inotropic score after portal vein opening were lower in the CO-G group(P<0.05).Compared to the control group,serum inflammatory factors(interleukin-6 and tumor necrosis factor-α),cardiac troponin I,and N-terminal pro-brain natriuretic peptide were lower in the CO-G group after the operation(P<0.05).CONCLUSION CO-G hemodynamic management in pediatric living-donor LT decreases the incidence of early postoperative ALI due to hemodynamic stability through optimized fluid management and appropriate administration of vasopressors and inotropes.
