However, its use as a cerebral protector is not recommended by several authors because its seizure-like activity after anesthesia. More extensive studies are needed regarding propofol before it can be recommended as a cerebral protector. The rupture of an aneurysm can take place during induction or during surgery. The appearance of rupture during induction has devastating consequences. The appearance of hypertension with or without bradycardia will suggest the possibility of rupture of the aneurysm.
Hemodynamic alterations can be slight in the anesthetized patient.
The ultrasound transcranial doppler can be used in order to detect a rupture of an aneurysm after induction . If the rupture of the aneurysm takes place during the craniotomy, priority will be to control hemorrhage. Induced hypotension reduces rebleeding and facilitates surgical exposure. Homeostasis can also be obtained by using a temporary or permanent clip. The degree of rebleeding in aneurysms of the anterior circulation can be reduced by manual compression the ipsilateral carotid artery for short periods of time.
