[Controlled arterial hypotension using nitroglycerin in brain surgery].

Artificial hypotension induced by 0.01% nitroglycerin solution was applied in 60 operations on the brain. It contributed to the creation of optimum conditions for radical removal of tumors and exclusion of vascular aneurysms, reduction of blood loss, and a decrease in the number of blood transfusion. The efficacy, adequate control, safety, and attainability of the method allowed it to be recommended for use in neurosurgical practice when necessary.
