BACKGROUND It is unclear when it is safe to discharge patients with a diagnosis of Obstructive Sleep Apnea (OSA) after ambulatory surgical procedures due to concern for postoperative respiratory compromise and hypoxemia. Our OSA patients undergoing ambulatory-type orthopedic procedures are monitored overnight in the PACU, thus we reviewed patient records to determine incidence of complications....
Cardiovascular responses to acute hypoxemia are in part mediated through adrenergic and chemoreceptor stimulation. In chronic hypoxemia the response to these stimuli may be blunted. Therefore, we determined whether the cardiovascular responses to acute hypoxemia superimposed on 3-4 wk of chronic hypoxemia were blunted in lambs with an experimental cardiac right-to-left shunt (combination of atr...
Fetal endocrinological responses to chronic hypoxemia are useful in elucidating the process of growth restriction at earlier stages of fetal development. The purpose of this study was to observe endocrinological responses to prolonged (24-h) non-acidemic hypoxemia in preterm goat fetuses. Fetal hormonal changes were examined in chronically instrumented goat fetuses at gestational day 96-102 (0....
Pneumonia is the leading cause of death in children. The objectives were to evaluate the microbiological agents linked with hypoxemia in hospitalized children with pneumonia from developing countries, to identify predictors of hypoxemia, and to characterize factors associated with in-hospital mortality. A multicenter, observational study was conducted in five hospitals, from India (Lucknow, Vad...
The effects of fetal hypoxemia on renal hemodynamics and renal function were studied in two groups of chronically catheterized young (< 120 days of gestation) and near-term lamb fetuses (> 130 days). Fetal hypoxemia produced, in both groups, a significantly decrease in renal blood flow (RBF) and a significant increase in the filtration fraction. However, the glomerular filtration rate (GFR) did...
BACKGROUND In adequately resourced clinical environments, diagnosis of hypoxemia via pulse oximetry is routine. Unfortunately, pulse oximetry is rarely utilized in under-resourced hospitals in developing countries. AIM The prevalence of undiagnosed hypoxemia among adults and children with illnesses other than pneumonia in these environments remains poorly described. METHODS This cross-secti...
