Warm donor organ perfusion systemsPersufflation gaseous oxygen perfusion as a method of heart preservation. Vascular thrombosis in machine-perfused renal allografts. Perfusates for long-term preservation by continuous perfusion. Reimplantation was followed by immediate contralateral nephrectomies. The kidneys remained in iced saline for the rest of the storage period. A membrane lung was used for oxygenation to avoid damaging the blood. It is an alternative to CS. Conflict of interest The author IC Post received technical support from Bronkhorst High-Tech, the manufacturer of the Coriolis-based flow sensor, but without benefits or restrictions in the publication of results. However, delayed contralateral nephrectomy 4 weeks after reimplantation was necessary in these experiments to achieve success, and this indicated that the kidneys were severely injured during storage. Pulsatile perfusion preservation of warm ischaemia-damaged experimental kidney grafts.J Thorac Cardiovasc Surg. The perfusion system was driven by a rollerpump Watson-Marlow, Wilmington, MApumping perfusion solution from the reservoir to the first bubble trap while a miniature membrane pump NF60KPDCB-4, KNF Neuberger GMBH, Freiburg, Germany provided the arterial perfusion pressure after the first bubble trap. However, dog kidney slices were less severely affected by the rapid cooling than were the liver slices. This protective effect of hypothermia on renal ischaemic damage was confirmed by Bogardus who showed a protective effect from surface cooling of dog kidneys whose renal pedicles were clamped in situ for 2 hours. The presented preservation system proved to provide accurate flow and pressure management throughout temperature and preservation solution changes.Advances in machine perfusion graft viability assessment in kidney, liver, pancreas, lung, and heart transplant. Successful transplantation of rat hearts subjected to extended cold preservation with a novel preservation solution. Novel Coriolis-type mass flow sensors CFS may be more suitable for MPS because the measurement technique is not amenable to these factors. Donation after circulatory death: current practices, ongoing challenges and potential improvements. The aim of this study was to determine the accuracy of flow measurements using ultrasonic- and Coriolis-based flow sensors with respect to temperature-dependent viscosities and pressure variations of the following preservations solutions: University of Wisconsin UWhistidine—tryptophan—ketoglutarate HTKand the experimental preservation solution, Polysol PS. Heart preservation for transplantation: principles and strategies. A cardioprotective preservation strategy employing ex vivo heart perfusion facilitates successful transplant of donor hearts after cardiocirculatory death. Prevention of reperfusion injury in the neonatal heart with leukocyte depleted blood. The may contain suggestions.Warm donor organ perfusion systemsFatty acid and glucose utilisation during continuous perfusion of dog kidney. Without the methyl prednisolone, Woods found resistance fragility to be a problem when storage times were longer than 48 hours. Fuhrman showed that slices of kidney cortex and file withstood cooling to 0. Three- and seven-day perfusion of dog kidneys with human plasma protein fraction IV-4. North described similar hyperacute rejection following perfusion storage and showed that the cryoprecipitated plasma used contained cytotoxic IgM antibody.Due to this property, experimental machine perfusion systems with Coriolis-based flow sensors might enable reproduction of clinically and experimentally encountered flow dynamics with a greater accuracy under changing preservation conditions. However, Liu performed no control experiments to show that these modifications were crucial.
