Assessment of Tiredness During Awake Resection of Intracerebral Tumors

Occasional patients with intracranial tumors need to have a planned awakening during surgery to avoid major disability from the tumor resection. During the awake part of the surgery an increasing degree of tiredness is observed. For the surgeon to plan the resection knowledge of the degree and speed of tiredness/sleepiness evolution is important.

The goal of this single center study is to use the "Karolinska Sleepiness Scale" during and after awake surgery for neurosurgical tumor resection to quantify the time available for surgical intervention.

Participants are adults having planned surgery for open resection of intracranial tumor with a planned awakening for assessment during surgery. Participants will be asked to grade postoperative sleepiness using the "Karolinska Sleepiness Scale".
