Controversial Issues in Neuroanaesthesia

چکیده
1. Controversies related to use of drugs in neuroanaesthesia: Controversies regarding the provision of anaesthesia for intracranial neurosurgery remain, with no ideal technique identified Despite the theoretical benefits of intravenous agents, volatile agents remain popular. In a study comparing desflurane, isoflurane and sevoflurane in a porcine model of intracranial hypertension, at equipotent doses and normocapnia, cerebral blood flow (CBF) and intracranial pressure (ICP) were greatest with desflurane and least with sevoflurane The same authors also confirmed that sevoflurane also caused least vasodilation In two separate studies, isoflurane was seen to impair autoregulation, although reversible with hyperventilation, while autoregulation was virtually intact with sevoflurane 1 – 1.2 % at normocapnia Although large studies may be needed, sevoflurane appears to be the most suitable volatile agent for neuroanaesthesia practice.

متن کاملAnaesthesia for interventional neuroradiology.
Neuroradiologists have extended their treatment modalities in the field of vascular neurosurgery. The rapidly emerging and re-engineered neuroradiological techniques confront the anaesthetist with an increasing number of patients with severe neurological disease. More of these patients will need general anaesthesia in order to facilitate the endovascular procedure, including catheter placement,...
متن کاملDesflurane results in higher cerebral blood flow than sevoflurane or isoflurane at hypocapnia in pigs.
BACKGROUND In clinical neuroanaesthesia, the increase in cerebral blood flow (CBF) and intracranial pressure caused by the cerebral vasodilative effects of an inhalational anaesthetic agent is counteracted by the cerebral vasoconstriction induced by hypocapnia. Desflurane and sevoflurane may have advantages over the more traditionally used isoflurane in neuroanaesthesia but their dose-dependent...
