Mechanisms of hypoxemia in patients with status asthmaticus requiring mechanical ventilation.

Numai utilizatorii înregistrați pot traduce articole

Eight consecutive patients (mean +/- SD age, 43 +/- 11 yr) with acute severe asthma (status asthmaticus) requiring assisted ventilation were studied within the first 24 to 48 h of admission, at maintenance FIO2 and while breathing 100% O2, using the multiple inert gas elimination technique.

[Experiences with the application of mechanically controlled hypoventilation in status asthmaticus].

The study reported the successful application of mechanical controlled hypoventilation in 3 cases of severe ventilatory failure secondary to status asthmaticus. The results are attributed to a strategy The aim of early ventilatory support is to correct hypoxemia,, reduce respiratory work and avoid

Status asthmaticus. A nine-year experience.

Numai utilizatorii înregistrați pot traduce articole

A retrospective analysis of 811 patients admitted to the hospital for status asthmaticus over a nine-year period was performed. Eight patients died, and 19 required mechanical ventilation. All persons who died of status asthmaticus were in the group that required mechanical ventilation. In 12 of the

Mechanical controlled hypoventilation in status asthmaticus.

This study reports the results obtained with mechanical ventilation in severe respiratory failure secondary to status asthmaticus. Of the 159 patients with status asthmaticus admitted to the Intensive Respiratory Unit over a 5-yr period, 26 required mechanical ventilation for a total of 34 episodes

Emergency extracorporeal life support for patients with near-fatal status asthmaticus.

Numai utilizatorii înregistrați pot traduce articole

Extracorporeal life support (ECLS) was used to treat three patients with near-fatal status asthmaticus who did not respond to aggressive medical therapies and mechanical ventilation under controlled permissive hypercapnia. ECLS was instituted in patient 1 because PaCO2 was excessively high and pH

P pulmonale in status asthmaticus.

Numai utilizatorii înregistrați pot traduce articole

We studied 129 patients during acute, severe asthmatic attacks. Electrocardiograms showed P pulmonale in 49% of patients who had an arterial carbon dioxide tension (PaCo2) greater than or equal to 45 mm Hg and an arterial pH less than or equal to 7.37, whereas P pulmonale was present in only 2.5% of

Transient intrapulmonary shunting in a patient treated with β₂-adrenergic agonists for status asthmaticus.

Intrapulmonary arteriovenous anastomoses (IPAVs) are large-diameter pathways that directly connect the arterial and venous networks, bypassing the pulmonary capillaries. Ubiquitously present in healthy humans, these pathways are recruited in experimental conditions by exercise, hypoxia, and

Rhabdomyolysis and renal failure following status asthmaticus.

Acute renal failure developed in a 25-year-old man following status asthmaticus. He was found to have myoglobinuria. Vigorous contraction of the respiratory muscles and hypoxia were considered to be responsible for the development of myoglobinuria. Associated dehydration, in the presence of

Successful weaning using noninvasive positive pressure ventilation in a patient with status asthmaticus.

Numai utilizatorii înregistrați pot traduce articole

In the treatment of severe asthma attack, acute application of non-invasive positive pressure ventilation is shown to be beneficial in some selected patients, while endotracheal intubation and mechanical ventilation is required in the remaining cases. Management with invasive ventilation in status

Mechanical ventilation for status asthmaticus in children.

Numai utilizatorii înregistrați pot traduce articole

We retrospectively reviewed the time course of recovery of pediatric patients in status asthmaticus who were undergoing mechanical ventilation for life-threatening respiratory failure to evaluate the results with current medications and technology. Ten patients between 2 and 18 years of age

Nonobstetric conditions causing hypoxia during pregnancy: asthma and epilepsy.

Numai utilizatorii înregistrați pot traduce articole

Nonobstetric medical emergencies of hypoxia may be difficult to recognize in pregnant patients whose normal physiologic condition is altered by the pregnant state. Keys to early recognition of hypoxia in pregnancy may result in appropriate medical interventions for treatment of asthma and seizures

Persistent hypoxemia after an asthma attack.

Numai utilizatorii înregistrați pot traduce articole

The presence of an unknown intracardiac shunt due to a patent foramen ovale may be an unusual cause of hypoxemia. We report the case of a patient who presented persistent hypoxemia after an adequate treatment for a severe asthma attack requiring intensive care unit admission. The patient underwent a

Management of the obstetric patient with status asthmaticus.

Numai utilizatorii înregistrați pot traduce articole

Status asthmaticus requiring mechanical ventilation is an uncommon, life-threatening disorder in obstetric patients. The unique physiologic changes of pregnancy, impact of the fetus on the maternal condition, and concerns for fetal and maternal health and survival are particular concerns in critical
