Case ReportsLiver transplantation in hyponatremic patients with emphasis on central pontine myelinolysis.
Patients awaiting liver transplantation may suffer from severe hyponatremia. It has been suggested that hyponatremia or its treatment might be associated with central pontine myelinolysis (CPM), a serious complication that can be seen after orthotopic liver transplantation (OLT). We undertook this study to assess the outcome of hyponatremic patients after OLT and to evaluate the risk factors in the development of CPM. ⋯ No other risk factor could be identified in the development of CPM. It is concluded that prognosis of hyponatremic patients after OLT is poor if they develop CPM. Slow correction of hyponatremia perioperatively may be critical in preventing this devastating complication.

Infection and associated risk factors in the immediate postoperative period of pediatric liver transplantation: a study of 176 transplants.
To describe the characteristics of infections occurring in the immediate postoperative period of orthotopic liver transplantation (OLT) in children in a pediatric intensive care unit (PICU) and the associated risk factors. ⋯ Infection in the immediate postoperative period of pediatric OLT was related with a high morbidity but was not related significantly with increased mortality. The main risk factors for infection in the postoperative period of OLT were related essentially with small recipient size and the inherent complexity of the operation. Routine oropharyngeal decontamination is recommended, as well as early administration of oral nystatin in preoperative intestinal decontamination. The risk of infection increased 2.38 times with partial grafts and 1.1 times with the transfusion of every 20 ml of packed RBC.

Effects of low-dose dopamine on urine output in oliguric, critically ill, renal transplant patients.
Low-dose dopamine (LD-DA) has been used extensively to increase urine output (UO) in critically ill patients. These effects have recently been documented in patients with normal and mildly abnormal renal function. The purpose of this study was to quantitate the effects of LD-DA on UO and urineNa (UNa) excretion in renal transplant (RT) patients, and thereby evaluate the effects of LD-DA on the denervated kidney. ⋯ LD-DA increases UO, but not UNa excretion, in RT patients with oliguria, comparably to controls. These data suggest that this effect is predominantly mediated by dopaminergic receptors, since the transplanted kidney is denervated and there were no significant associated changes in hemodynamic parameters during the study.
