Mild hypothermia during the reperfusion phase protects mitochondrial bioenergetics against ischemia-reperfusion injury in an animal model of ex-vivo liver transplantation-an experimental study.

Mild hypothermia during the reperfusion phase protects mitochondrial bioenergetics against ischemia-reperfusion injury in an animal model of ex-vivo liver transplantation-an experimental study. Int J Med Sci. 2019;16(9):1304-1312 Authors: Martins RM, Teodoro JS, Furtado E, Oliveira RC, Tralhão JG, Rolo AP, Palmeira CM Abstract The organ preservation paradigm has changed following the development of new ways to preserve organs. The use of machine perfusion to preserve organs appears to have several advantages compared with conventional static cold storage. For liver transplants, the temperature control provided by machine perfusion improves organ preservation. In this experimental study, we measured the effects of different temperatures on mitochondrial bioenergetics during the reperfusion phase. An experimental model of ex-vivo liver transplantation was developed in Wistar rats (Rattus norvegicus). After total hepatectomy, cold static preservation occurred at 4ºC and reperfusion was performed at 37ºC and 32ºC using a Langendorff system. We measured parameters associated with mitochondrial bioenergetics in the livers. Compared with the livers that underwent normothermic reperfusion, mild hypothermia during reperfusion caused significant increases in the mitochondrial membrane potential, the adenosine triphosphate content, and mitochondrial respiration, and a significant reduction in the lag phase (all P

Objectives: To investigate the impact of normothermia on compliance with sepsis bundles and in-hospital mortality in patients with sepsis who present to emergency departments. Design(s): Retrospective multicenter observational study. Patient(s): Nineteen university-affiliated hospitals of the Korean Sepsis Alliance participated in this study. Data were collected regarding patients who visited emergency departments for sepsis during the 1-month period. The patients were divided into three groups based on their body temperature at the time of triage in the emergency department (i.e., hypothermia [ 38degreeC]). Intervention(s...

In the world literature there is a lot of information about the activity of liquid preservatives and solutions being their modifications. However, there is no information about the possibility of interactions between them during multi-organ retrieval. Therefore, the aim of the undertaken research was to analyse the possibility of reactions between the components of Biolasol and HTK. Biolasol ® is the first Polish liquid preservative intended for rinsing kidneys, livers and pancreases by simple hypothermia.

Background: Abrupt temperature shift from hypothermia to normothermia incurred on reperfusion of organ grafts has been delineated as a genuine factor contributing to reperfusion injury and graft dysfunction after transplantation. Methods: In a first clinical series of 6 patients, cold-stored livers, all allocated by the rescue offer mechanism by Eurotransplant, were subjected to machine-assisted slow controlled oxygenated rewarming (COR) for 90 minutes before engrafting. A historical cohort of 106 patients basically similar in graft (all rescue offer organs) and recipient factors was used for comparison. Results: The clini...
