OBJECTIVE Inhalation injury is suspected in patients with facial and neck burn-injuries and in patients who suffered burns in an enclosed space. Inhalation injury is associated with a disappointingly high morbidity and mortality in spite of advances in diagnostics and therapy.Prophylactic antibiotic therapy in patients with diagnosed inhalation injury is still a controversial subject.The epidem...

BACKGROUND AND PURPOSE The aim of the present study was to investigate the effects of normobaric oxygen (NBO) therapy on T2*-weighted images of intracranial hemorrhages (ICHs). METHODS Two common models of ICH were performed in mice, and longitudinal T2*-weighted images of the hematomas were acquired under normoxia or NBO. The effects of NBO were also investigated on perfusion-weighted imagin...

OBJECTIVE To evaluate the alterations of heart rate, blood pressure, psychological aspects and oxygen saturation after continuous fenoterol inhalation (0.5 mg/Kg) by children with severe acute asthma. METHODS We studied 30 patients with severe acute asthma who were treated at the pediatric ward of Hospital Universitário-UFMS. The patients inhaled 0.5 mg/Kg of fenoterol (two drops/Kg) during o...

BACKGROUND Steam inhalation therapy is often recommended in the treatment of a common cold. However, it has no proven benefit and may in fact have serious adverse side effects in terms of burn injuries. AIM To quantify the human and economic costs of steam inhalation therapy in terms of burn injury. DESIGN AND SETTING A prospective database study of all patients admitted to the burn centres...

Inhalation of partially ionized oxygen may have less adverse effects on lung functions than medical oxygen. Guinea pigs inhaled air, 100% molecular medical oxygen (O(2)mol), partially negatively (O(2)neg) or positively (O(2)posit) ionized oxygen during 17 and 60 h. After 17 h, dityrosines, markers of oxidative injury, in lung homogenate increased in O(2)neg and decreased in O(2)posit groups vs....

PURPOSE To test the hypotheses that, in mice, breathing carbogen (95% O(2)-5% CO(2)) oxygenates the retina better than breathing 100% oxygen, the superior hemiretinal oxygenation response to carbogen inhalation is subnormal early in diabetes, and diabetes-induced elevation of retinal protein kinase C (PKC)-beta contributes to this pathophysiology. METHODS Retinal oxygenation response (DeltaPO...

Introduction Hyperbaric oxygen (HBO2) therapy involves the inhalation of pure in a pressure chamber under increased ambient pressure. Recent research indicates that circulating small extracellular vesicles (sEVs) play important roles human physiology and pathology. Therefore, objective this pilot study was to monitor impact HBO2 on levels sEVs serum patients with necrotizing soft-tissue infecti...

Am J Physiol Heart Circ Physiol 292: H776–H785, 2007. First published October 20, 2006; doi:10.1152/ajpheart.00381.2006.— Oxygen inhalation is recommended for the initial care of trauma victims. The improved survival seen in early hemorrhage is norma...

1. Cerebral blood flow, oxygen and glucose consumption, hind-limb blood flow and oxygen consumption, blood pressure and heart rate were measured in seven ventilated dogs. 2. Inhalation of 5% C 0 2 caused a significant increase in cerebral blood flow and a significant decrease in cerebral glucose utilization. 3. Isoprenaline infusion (0.4 pg kg-I min-') caused a rise in cerebral blood flow, oxyg...
