Final answer:
The type of anesthetic for endovascular neurologic surgery depends on various factors. Commonly used anesthetics include general anesthetics and local anesthetics. General anesthetics induce loss of consciousness, while local anesthetics block sensation by blocking nerve signals.
Step-by-step explanation:
The type of anesthetic that should be used for endovascular neurologic surgery depends on various factors, such as the specific procedure, patient's condition, and the surgeon's preference. However, commonly used anesthetics in such surgeries include general anesthetics and local anesthetics.
General anesthetics are administered to induce a reversible loss of consciousness and can be given as inhalational gases or intravenous injections. Examples of general anesthetics used in neurologic surgeries include propofol and ketamine.
Local anesthetics, on the other hand, are applied directly to the nerves in the surgical area to block sensation. Lidocaine and novocaine are examples of local anesthetics that work by blocking sodium channels and preventing the conduction of nerve signals.
