Medical hypotheses
-
Neurogenic pulmonary edema is an acute life-threatening complication of central nervous system injury. We introduce a hypothesis that early i.v. administration of high-dose atropine can prevent neurogenic pulmonary edema development on the basis of the prevention of baroreflex-induced bradycardia, which was recognized as a major factor in neurogenic pulmonary edema formation. To validate this hypothesis, a clinical trial in patients suffering from subarachnoid haemorrhage should be performed, with atropine administered i.v. immediately after the maintenance of the living functions, intubation and ability to monitor patient.
