Awake Craniotomy (AC) is a technique which has gained popularity since its conception in the 1800s. With its initial indication being for the treatment of seizures, we are now seeing its use for resecting tumors adjacent to eloquent and motor areas of the brain. The procedure allows maximum excision/resection of disease, whilst minimising post-operative neurological deficit.
The Anesthetic management has also evolved to include Local Anesthetic, Sedation and or General Anesthesia (GA). There are two techniques that comprise the mainstay of practice; Monitored Anesthesia Care (MAC) , Asleep-Awake-Asleep (SAS) with a newer Awake-Awake-Awake (AAA) technique also being utilised.
In this chapter, we will explore the different methods of anesthesia and describe the important anesthetic considerations that need to be borne in mind.
