Anatomical and functional intrapulmonary shunt in acute respiratory distress syndrome.
OBJECTIVES The lung-protective strategy employs positive end-expiratory pressure to keep open otherwise collapsed lung regions (anatomical recruitment). Improvement in venous admixture with positive end-expiratory pressure indicates functional recruitment to better gas exchange, which is not necessarily related to anatomical recruitment, because of possible global/regional perfusion modificatio...
متن کاملHypothermia in Uremic Dogs and Cats
BACKGROUND The prevalence of uremic hypothermia (UH) and the effects of improving uremia on body temperature have not been determined in veterinary patients. OBJECTIVES To determine the prevalence of UH and correlations between uremia and body temperature in patients undergoing intermittent hemodialysis (IHD). ANIMALS Uremic dogs (n = 122) and cats (n = 79) treated by IHD at the Bobst Hospi...
متن کاملThe effects of dobutamine and dopamine on intrapulmonary shunt and gas exchange in healthy humans.
The development of intrapulmonary shunts with increased cardiac output during exercise in healthy humans has been reported in several recent studies, but mechanisms governing their recruitment remain unclear. Dobutamine and dopamine are inotropes commonly used to augment cardiac output; however, both can increase venous admixture/shunt fraction (Qs/Qt). It is possible that, as with exercise, in...
متن کاملBeneficial effect of mild hypothermia and detrimental effect of deep hypothermia after cardiac arrest in dogs.
BACKGROUND AND PURPOSE Mild cerebral hypothermia (34 degrees C) induced immediately after cardiac arrest improves outcome. Deep postarrest hypothermia (15 degrees C) has not been studied. METHODS We used our dog model of normothermic ventricular fibrillation (no blood flow) of 12.5 minutes, reperfusion by brief cardiopulmonary bypass, controlled ventilation to 20 hours, and intensive care to ...
متن کاملIntrapulmonary arteriovenous shunt in children with chronic liver disease: clinical features, laboratory data and outcome.
OBJECTIVE To determine the frequency of hepatopulmonary syndrome in children with chronic liver disease, and its clinical and biochemical associations. METHOD This study included 53 children with chronic liver disease, who underwent contrast echocardiography with agitated saline and measurement of arterial blood gases. RESULTS Of the 53 patients studied, 18 had intrapulmonary shunting of bl...
