Organ perfusion during controlled hypotension.
Relatively short periods of unwanted hypotension, such as those associated with "shock" states, may be followed by irreversible organ damage. In contrast, controlled hypotension is rarely followed by organ damage, although minor reversible changes in function may occur (Rollason and Hough, 1960; Enderby, 1961; Linacre, 1961). The usual explanation for this paradox is that in the former situatio...
متن کاملHaemoglobin, oxygen carriers and perioperative organ perfusion.
Under normal conditions, only 20-30% of the delivered oxygen is metabolised. In normovolaemic anaemia, the organism reacts with increases in cardiac output and oxygen extraction. Once these mechanisms are exceeded, allogeneic blood transfusions may be administered. However, such transfusions are associated with serious adverse effects and alternatives such as artificial oxygen carriers are bein...
متن کاملCatheter effects in organ perfusion experiments.
In a typical isolated organ perfusion experiment, a substance is injected upstream of an organ and then collected at some distance downstream. To reach the organ from the injection site, and then from the organ to the collector, a solute passes through catheters, usually tubes with circular cross-sections. Catheters cause distortion to the concentration-time profile of the perfusion. In this pa...
متن کاملExtracorporeal Free Flap Perfusion in Case of Prolonged Ischemia Time
In free flap surgery, a clinically established concept still has to be found for the reduction of ischemia-related cell damage in the case of prolonged ischemia. Although promising results using extracorporeal free flap perfusion in the laboratory have been published in the past, until now this concept has not yet paved its way into clinical routine. This might be due to the complexity of perfu...
متن کاملEffects of prolonged pneumoperitoneum on hepatic perfusion during laparoscopy.
OBJECTIVE To assess the influence of prolonged pneumoperitoneum (PP) on liver function and perfusion in a clinically relevant porcine model of laparoscopic abdominal insufflation. BACKGROUND PP during laparoscopic surgery produces increased intra-abdominal pressure, which potentially influences hepatic function and microcirculatory perfusion. METHODS Six pigs (49.6 ± 5.8 kg) underwent lapar...
