High-altitude pulmonary edema: a clinical crisis

Article Abstract:

High-altitude pulmonary edema (HAPE) must be promptly recognized and treated or death may ensue. It occurs in otherwise healthy individuals who rapidly ascend to 10,000 feet altitude or more without acclimatizing. Research into the mechanism causing HAPE continues. Symptoms begin with cough, shortness of breath, and fatigue, progressing to ataxia, confusion, lethargy, and dyspnea. Descent is the cure, but if that is impossible, bed rest while semireclining, oxygen, intravenous morphine, and diuretics are temporary supportive measures.

Closure of the ductus arteriosus--new insights for critical care

Article Abstract:

There are new insights into the closure of the ductus arteriosus and critical care. They may lead to more effective nonsurgical treatment in patent ductus arteriosus. It may be that ET-1 agonists will prove useful in the future in pharmacologic interventions. Factors involved include carbon monoxide, cytochrome P450, endothelin, nitric oxide and prostaglandin E2.
