RESUMO
Objective To analyze the correlation between the status of the donation after brain and cardiac death (DBCD)donors and postoperative recovery of the organ function in the liver and renal transplant recipients.Methods The assessment data and organ protection measures of 12 DBCD donors admitted to the Organ Transplantation Center in Sichuan Provincial People’s Hospital from August 2011 to November 2013 were retrospectively analyzed.The parameters of postoperative recovery of 12 liver and 22 renal transplant recipients were also assessed.The correlation between the parameters of the donors and postoperative recovery of the liver and renal transplant recipients was statistically analyzed.Results Among 12 liver transplant recipients,1 patient had primary non-function (PNF)(1 /12,8%)and 11 cases developed delayed graft function (DGF) after renal transplantation (11 /22,50%).Intensive care unit (ICU)period,liver function,maintaining systolic blood pressure (SBP),blood coagulation function,blood glucose level and electrolyte (Na +/K +) were significantly correlated with postoperative recovery of the liver and kidney function in the recipients (all in P <0.05 ).Age,cause of brain death,maintaining diastolic blood pressure (DBP),activated partial thromboplastin time (APTT)and pH of arterial blood gas (ABG)were associated with postoperative recovery of the liver function.Total bilirubin and white blood cell count (WBC)were correlated with postoperative recovery of kidney function.Conclusions DBCD donors cater to the specific conditions in China.The incidence of postoperative PNF in liver recipients is relatively low whereas and the incidence of DGF after renal transplantation is relatively high.Assessment of the DBCD donors and organ protection measures should be specifically taken to enhance the clinical efficacy of liver and renal transplantation from DBCD donors.
RESUMO
Objective To evaluate the effects of asymptomatic arteriovenous fistula closure on left ventricular morphology and function in renal transplant recipients.Methods Between March 2007 and March 2011,a total of 60 patients undergoing consecutive kidney transplantation with asymptomatic arteriovenous fistula were divided randomly into two groups: arteriovenous fistula closure group,and non-arteriovenous fistula closure group.By using echocardiography,the changes in CO,CI,EF,LVEDV and LVMI were analyzed.Results At 12th month after transplantation,the values of CO,LVEDV and LVMI were significantly lower than those before transplantation (P＜0.05).The value of CI also showed a tendency to decrease (P＞0.05),and the value of EF was increased significantly (P＜0.05).At 6th month after arteriovenous fistula closure (18 months after transplantation),the values of CO,CI,LVEDV and LVMI were significantly lower than those before arteriovenous fistula closure (12 months after transplantation) (P＜0.05),and the value of EF was increased significantly (P＜0.05),but the values of CO,CI,EF,LVEDV and LVMI remained unc(b)anged in controls (P＞0.05).At 18th month after transplantation,the values of CO (4.4 ±0.8 L/min),CI [3.0 ± 0.8 L·min-1·m-2],LVEDV (110.0 ± 17.4 ml) and LVMI (114.7 ± 42.5g/m2) in trial group were significantly lower than the values [CO: 5.1 ± 0.9 L/min,CI: 3.5 ± 1.0L·min-1·m-2,LVEDV: 121.4±19.3 mL,LVMI: 138.4±44.1 g/m2] in controls (P＜0.05),and the value of EF (75.2％ ± 7.4％ vs.70.5％ ± 8.2％) significantly higher (P＜005).Conclusion In both groups,kidney transplantation benefits significantly the regression of cardiac mass,cardiac index and left ventricular dimensions,but closure of asymptomatic AVF induces more significant regression.
