acute respiratory distress syndrome (ards) is a potential complication of cardiac surgery, given that patients undergoing cabg frequently have hypoxemia and pulmonary dysfunction during initial hours after surgery. thus, ards criteria in these patients are more likely to be positive while these criteria may not match the patient`s clinical picture. we aimed to investigate frequency of rapid ons...
In this prospective study the effect of low dose methylprednisolone succinate (10mg/kg) on the incidence of fat embolism syndrome and isolated arterial hypoxemia in 99 patients with long bone fracture (52 control and 47 steroid-trated subjects) was studied. Frequency of fractures among the selected patients was as follows: femoral fracture 52.5%, tibial fracture 36.4%, both femoral and tibial f...
OBJECTIVE Cyanotic patients have potentially decreased tissue oxygen tension. Cytochrome oxidase catalyzes the reduction of oxygen and is integral to adenosine triphosphate production. Cytochrome oxidase subunit I, the active site, is encoded by mitochondrial DNA. Using a newborn swine model of chronic hypoxemia, we evaluated ventricular cytochrome oxidase subunit I mRNA and protein expression ...
Adrenal gland blood flow (ABF) increases during hypoxemia in fetal sheep, but regulation of ABF is poorly understood. The purpose of this study was to determine the effects of splanchnic nerve section on fetal ABF responses to hypoxemia using the fluorescent microsphere (FM) technique. At 125 days of gestation, 14 unanesthetized fetal sheep [bilateral splanchnicotomy (Splx, n = 6) and control (...
In newborns and adults of a number of species, exposure to acute hypoxemia produces a "regulated" decrease in core temperature, the mechanism of which is unknown. The present experiments were carried out on chronically instrumented newborn (5-10 days of age; n = 27) and older (25-30 days of age; n = 23) guinea pigs to test the hypothesis that adenosine mediates this regulated decrease in core t...
