Oxygen delivery during retrograde cerebral perfusion in humans.
UNLABELLED Retrograde cerebral perfusion (RCP) potentially delivers metabolic substrate to the brain during surgery using hypothermic circulatory arrest (HCA). Serial measurements of O2 extraction ratio (OER), PCO2, and pH from the RCP inflow and outflow were used to determine the time course for O2 delivery in 28 adults undergoing aortic reconstruction using HCA with RCP. HCA was instituted af...
متن کاملA reappraisal of retrograde cerebral perfusion.
Brain protection during aortic arch surgery by perfusing cold oxygenated blood into the superior vena cava was first reported by Lemole et al. In 1990 Ueda and associates first described the routine use of continuous retrograde cerebral perfusion (RCP) in thoracic aortic surgery for the purpose of cerebral protection during the interval of obligatory interruption of anterograde cerebral flow. T...
متن کاملDynamic cerebral autoregulation and monitoring cerebral perfusion.
Cerebral autoregulation (CA) describes the capability of the brain to maintain its flow as relatively stable over a wide rage of mean arterial pressures (MAPs), for example, from 60 to 150 mm Hg. Because the brain is encompassed in the skull, CA is vital for preventing cerebral edema and hemorrhage, as illustrated in some patients experiencing acute liver failure.1 Also, CA counteracts the effe...
متن کاملTolerance of the cerebral venous system to retrograde perfusion pressure in focal cerebral ischemia in rats.
Using quantitative double-tracer autoradiography, we examined the tolerance of the rat cerebral venous system in focal cerebral ischemia to retrograde perfusion pressure into the inferior cerebral vein. At perfusion pressures of less than 150 mm Hg, there was no significant change in local cerebral blood flow (LCBF) and blood-brain barrier (BBB) permeability. At pressures of greater than 170 mm...
متن کاملIncreased cerebrovascular resistance after retrograde cerebral perfusion: a Doppler study.
Deep hypothermic circulatory arrest (DHCA) with retrograde cerebral perfusion (RCP) under high central venous pressure (CVP) is often used in aortic arch surgery under cardiopulmonary bypass (CPB). We hypothesized that DHCA with RCP under high CVP causes cerebral vascular compression because of increased perivascular pressure due to extravasation of fluid into intracranial tissue. In a retrospe...
