Assessment of Sleepiness During Awake Brain Tumor Surgery Using the Karolinska Sleepiness Scale

What this Trial Is About

Researchers are studying adults with intracranial tumors who undergo awake brain surgery to remove these tumors while minimizing damage to important brain areas. The study focuses on measuring how tired or sleepy patients become during and shortly after the awake part of the surgery. This is important because understanding the timing and degree of sleepiness can help surgeons plan the procedure better to avoid major disability. Participants receive general anesthesia during preparation and craniotomy, then are awakened to be awake and cooperative during tumor removal. Researchers use the Karolinska Sleepiness Scale KSS, a nine-point scale to assess sleepiness every 15 minutes during surgery and for two hours after surgery. When the tumor removal is finished, patients are given anesthesia again for wound closure. During the study, data on patient details, tumor characteristics, and anesthesia parameters are collected. Participants will be asked to rate their sleepiness using the KSS during and after surgery. The main measurement is how the KSS score changes over time. The study will include at least 10 participants and aims to describe the pattern of sleepiness during the procedure.
