Key result
Pulmonary edema following subarachnoid hemorrhage can occur early due to catecholamine discharge or later due to cardiac failure and fluid overload, requiring careful identification of causes.
Why the study?
Pulmonary edema after subarachnoid hemorrhage can impair arterial oxygenation critical for brain recovery, and its causes require identification for appropriate treatment.
Pulmonary edema after subarachnoid hemorrhage has multiple etiologies including catecholamine surge and cardiac failure, necessitating accurate identification for proper treatment.
Demands etiology-specific therapy in subarachnoid hemorrhage pulmonary edema; leaves open prospective trials to define optimal diagnostic and management algorithms.
Pulmonary edema (PE) can occur after subarachnoid hemorrhage and can jeopardize arterial oxygenation, which is essential for a suffering brain. In some cases PE is evident in the emergency room, being the direct consequence of intracranial bleeding, which causes an immediate and overwhelming catecholamine discharge. In the following days, PE can occur because of cardiac failure, often related to initial cardiac damage, concurrent therapies with fluid overload and vasopressors, infections, or pre-existing co-morbidities. The causes of PE need to be identified for appropriate treatment.
