A case series of perioperative variables in relation to short-term outcomes in pediatric renal transplant recipients

: Multiple perioperative variables have been shown in existing literature to influence long-term outcomes of pediatric RTx, such as allograft survival. Their impact on short-term outcomes is not as well-documented. This case series aims to investigate the effects of nine perioperative variables on two short-term outcomes in pRTR: 1-week post-operative eGFR and post-operative LOS. A total of 73 pRTR transplanted over 3 years from 2012 to 2014 at a single center were studied retrospectively and statistical analyses were performed. There was higher 1-week post-operative eGFR in pRTR who received living donor transplants compared to those who received deceased donor transplants (P=.01), with mean eGFR of 135 mL/min/1.73 m2 and 82 mL/min/1.73 m2 , respectively. Aorta-IVC anastomosis was associated with longer LOS compared to iliac vessel anastomosis (P=.03), with median LOS of 19 and 13 days, respectively. There were no significant effects on 1-week eGFR or LOS of the seven other variables: pRTR age and gender, donor age, preoperative donor SBP, intraoperative mean CVP before graft perfusion, intraoperative median SBP z score after graft perfusion, and intraoperative fluid volume. Living donor transplants were associated with higher 1-week post-operative eGFR compared to deceased donor transplants. Aorta-IVC anastomosis was significantly associated with longer LOS compared to iliac vessel anastomosis.
