Objective To evaluate the effect of dexmedetomidine on myocardial injury in pediatric patients undergoing living-related liver transplantation. Methods Fifty-eight pediatric patients of both sexes,aged 5-20 months,weighing 4.5-15.0kg,of American Society of Anesthesiologists physical status Ⅲ or Ⅳ,scheduled for elective living-related liver transplantation,were divided into 2 groups(n=29 each)using a random number table:control group(group C)and dexmedetomidine group(group D).In group D,dexmedetomidine was intravenously infused at a dose of 0.5 μg/kg over 10min starting from the time point immediately before skin incision,followed by an infusion of 0.8 μg·kg-1·h-1 until the end of surgery. The equal volume of normal saline was given instead in group C. Immediately before skin incision(baseline,T0),at 10min of anhepatic phase(T1),at 30min of neohepatic phase(T2)and at the end of surgery(T3),blood samples were obtained from the central vein for determination of serum cardiac troponin I(cTnI),lactate dehydrogenase(LDH),alpha-hydroxybutyrate dehydrogenase(α-HBDH),interleukin-6(IL-6)and IL-10 concentrations. The changing rate of serum cTnI concentrations were calculated at T2. The occurrence of myocardial ischemia and ventricular premature beat and requirement for dopamine were recorded during surgery. Results Compared with the baseline at T0,the serum concentrations of cTnI,LDH and α-HBDH were significantly increased at T2,3,and the serum concentrations of IL-6 and IL-10 were increased at T1-3 in both groups(P<0.05).Compared with group C,the serum concentrations of cTnI,LDH,α-HBDH and IL-6 were significantly decreased at T2,3,the serum concentration of IL-10 was increased at T1-3,the changing rate of serum cTnI concentrations was decreased(P<0.05),and no significant change was found in the incidence of myocardial ischemia and ventricular premature beat and requirement for dopamine in group D(P>0.05).Conclusion Dexmedetomidine can attenuate the myocardial injury to some extent in pediatric patients undergoing living-related liver transplantation.

Objective:To evaluate the value of preoperative serum miRNA-146a-5p expression in predicting postoperative delirium (POD) in the pediatric patients undergoing living donor liver transplantation.Methods:Eighty pediatric patients with congenital biliary atresia, aged 5-12 months, with body mass index of 4-10 kg, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective living donor liver transplantation in our hospital, were selected. Venous blood samples were collected at 1 day before surgery, and serum miRNA-146a-5p expression was detected by quantitative real-time polymerase chain reaction. The children′s cognitive function was evaluated using the Mini-Mental State Examination and the Modified Montreal Cognitive Assessment at 1 day before operation and at 1, 3 and 7 days after operation. The pediatric patients were divided into POD group and non-POD group according to whether POD occurred within 7 days after surgery. Multiple logistic regression analysis was used to evaluate the relationship between serum miRNA-146a-5p expression and POD, Pearson′s correlation analysis was used to analyze the correlation between miRNA-146a-5p and POD, and the receiver operating characteristic curves were used to evaluate the accuracy of serum miRNA-146a-5p concentrations in predicting the occurrence of POD.Results:There were 30 cases in POD group and 50 cases in non-POD group, and the incidence of POD was 38%. The results of multiple logistic regression analysis showed that down-regulated serum miR-146a-5p expression was an independent risk factor for POD in pediatric patients undergoing living donor liver transplantation ( P<0.05). The incidence of POD was negatively correlated with serum miRNA-146a-5p expression ( r=-0.658, P<0.001). The area under the receiver operating characteristic curve of serum miRNA-146a-5p expression in predicting POD was 0.870 in pediatric patients undergoing living donor liver transplantation, with a sensitivity of 0.825 and a specificity of 0.875. Conclusions:Preoperative serum miRNA-146a-5p expression has a certain predictive value for POD in the pediatric patients undergoing living donor liver transplantation.
