Concerns about the adverse effects of hydroxyethyl starch (HES) on renal function have been raised in recent studies involving critically ill patients. We aimed to evaluate the effect of HES on acute kidney injury (AKI) after living donor right hepatectomy. ⋯ Intraoperative administration of HES may not be associated with AKI after living donor hepatectomy. This result can provide useful information on perioperative fluid management in living liver donors.

There is increasing evidence that the occurrence of small-for-size syndrome (SFSS) depends on portal hemodynamics rather than graft size. The portal hyperperfusion has been regarded as the most important contributing factor to SFSS. However, it is unknown how much portal vein flow (PVF) or what limit of PVF the liver remnant can sustain in extreme hepatectomy. This study aimed to evaluate the limit of portal hyperperfusion in a stable porcine model. ⋯ The deaths of animals in the 85% group supports the hypothesis that the remnant vascular bed with 15% of liver volume represents a critical residual liver parenchyma in pigs, the safe minimum residual liver volume should be >15% of liver volume, indicating that the liver remnant can regenerate successfully in ∼5.6 times baseline of PVF, whereas it fails to regenerate in >5.6 times baseline of PVF.

Hemostatic and coagulation disorders related to severe liver disease may cause massive bleeding beyond what can be expected from surgical trauma in liver transplantation. Fluid resuscitation and fibrinolysis may aggravate the problem, as plasma fibrinogen decreases in all patients. The objective of this review was to update the criteria for fibrinogen replacement in liver transplantation. ⋯ In liver transplantation, plasma fibrinogen levels are low in most patients during surgery. Fibrinogen administration to correct hypofibrinogenemia has a positive impact on surgical bleeding. However, there is a scarcity of literature about fibrinogen administration; therefore, administration should be adjusted to replace plasma fibrinogen levels in the range of normal and guided by thromboelastometry.

The use of pretransplantation extracorporeal membrane oxygenation (ECMO) has been considered to be a relative contraindication and a risk factor associated with poor outcomes in lung transplantation. However, with a donor shortage, use of ECMO before transplantation is often unavoidable. This study aimed to review our experiences of lung transplantation outcome with regards to the use of pretransplantation ECMO. ⋯ Use of pretransplantation ECMO did not jeopardize survival-to-discharge and short-term survival rates in our experience. Our result suggests pretransplantation ECMO can provide a chance of receiving lung transplantation to those who were classified as "too sick to be transplanted."

Observational Study
Non-Heart-Beating Donor Program: Results After 3 Years of Experience.
Non-heart-beating donation (NHBD) is a useful way to obtain organs and tissues. Therefore, since 2012 we have had an NHBD protocol in the metropolitan area of Seville. The aim of this work was to present the results obtained after 3 years of program. ⋯ NHBD is a useful program in our city with a low refusal rate (8%), an average of 1.45 organs per donor, and kidney the most frequent organ.
