Emad Aboud, The Aboud Model circulates blood-like perfusate
through a cadaver using a cardiac pump to simulate life-like conditions in terms of bleeding, pulsation and softness of tissue, providing surgeons the advanced training they need without the enhanced pressure of operating on a live patient.
Public health agency the US Food and Drug Administration announced on Friday that it authorised the marketing of the Xvivo Perfusion System with Steen Solution Perfusate
, which can temporarily ventilate, oxygenate and pump (perfuse) preservation solution through the transplant lungs that initially failed to meet standard transplant criteria.
Phthalate monoesters in perfusate
from a dual placenta perfusion system, the placenta tissue and umbilical cord blood.
samples were collected every five min for 60 min for further biochemical analyses.
Associations of perfusate
biomarkers and pump parameters with delayed graft function and deceased donor kidney allograft function.
The microdialysis system consisted of two syringe infusion pumps (CMA 400 and CM A 4004; CMA Microdialysis AB, Solna, Sweden) equipped with a total of eight glass microsyringes (2.5 ml) which were used to provide the perfusate
The fluid serving as the blood equivalent in perfusions is referred to as "perfusate
" and the pressure, flow rate and temperature the perfusate
is administered at are termed "perfusion pressure, perfusion flow and perfusion temperature", respectively.
Each NMP technology works on similar principles but differs in terms of portability, degree of automation, substrate type and delivery, pressure and pulsatility of the recirculating perfusate
, and hepatic arterial and portal vein flow targets [37, 38].
Higher levels of neutrophil gelatinase-associated lipocalin (NGAL) and L-type fatty acid binding protein (L-FABP) in donor urine or perfusate
[27, 28] can enhance prediction of DGF [27-29] and may become adopted in the future.
The opening of the arachnoid cisterns, vascular dissection, and microanastomosis can be performed very realistically in such a model although the actual "feel" of the vessel is usually altered (i.e., stiffened) as it is affected by the perfusate
samples are also collected from the hepatic veins.
