Glasgow Coma Scale (GCS) einfach erklärt
Summary
TLDRThis video explains the Glasgow Coma Scale (GCS), a clinical tool used to assess a person's level of consciousness based on eye opening, verbal response, and motor response. Developed in 1974, the GCS assigns points for each category, totaling a score between 3 and 15, which helps categorize brain injuries as mild, moderate, or severe. The video also covers how to apply the scale with real-life examples and includes a helpful mnemonic for quick memorization. It highlights the importance of the scale in trauma care and addresses limitations, including its inapplicability in certain cases, like intubation.
Takeaways
- 😀 The Glasgow Coma Scale (GCS) helps assess a person's level of consciousness quickly and uniformly, using three categories: eye opening, verbal response, and motor response.
- 😀 GCS was developed in 1974 by neurosurgeons Graham Teasdale and Bryan Jennett at the University of Glasgow, and is named after the Scottish city.
- 😀 Each of the three GCS categories (eye opening, verbal response, motor response) is evaluated on a scale and assigned a point value, which is then summed to give a score between 3 and 15.
- 😀 A GCS score of 13-15 indicates a mild traumatic brain injury (TBI), 9-12 represents a moderate TBI, and a score of 8 or lower signals a severe TBI.
- 😀 For assessing eye opening, points are assigned based on whether the eyes open spontaneously, to verbal stimuli, or only after a painful stimulus.
- 😀 Verbal response is evaluated on whether the person makes no sound, incomprehensible sounds, understandable words, disoriented speech, or is fully oriented and able to converse.
- 😀 The motor response category measures how the person reacts to pain, ranging from no movement to purposeful, targeted responses to pain.
- 😀 The GCS is useful in the clinical setting, allowing for rapid assessment of consciousness, which is particularly important for triaging patients with potential brain injuries.
- 😀 For patients who are intubated or otherwise unable to provide a verbal response, the GCS should be modified to note ‘NT’ (not testable) but not assign zero points.
- 😀 There is a pediatric version of the GCS, called the Pediatric Glasgow Coma Scale, designed for children, where the verbal response categories differ slightly.
- 😀 The acronym 'Eye, Talk, Bend' can serve as a mnemonic to remember the three GCS categories and their corresponding scores (Eye = 4, Talk = 5, Bend = 6).
Q & A
What is the purpose of the Glasgow Coma Scale (GCS)?
-The purpose of the Glasgow Coma Scale (GCS) is to quickly and uniformly assess a person's level of consciousness in clinical settings, specifically in cases of head injuries, to determine the severity of a brain injury.
What are the three categories assessed by the GCS?
-The three categories assessed by the GCS are eye opening, verbal response, and motor response.
How is the eye opening category scored in the GCS?
-Eye opening is scored as follows: 1 point for no eye opening, 2 points if the eyes open in response to pain, 3 points if the eyes open in response to speech, and 4 points if the eyes open spontaneously.
What are the different possible scores for verbal response in the GCS?
-The verbal response is scored as: 1 point for no verbal response, 2 points for incomprehensible sounds, 3 points for inappropriate words, 4 points for disoriented conversation, and 5 points for oriented conversation.
How is motor response evaluated in the GCS?
-Motor response is scored as follows: 1 point for no motor response, 2 points for abnormal extension (decerebrate posturing), 3 points for abnormal flexion (decorticate posturing), 4 points for withdrawal from pain, 5 points for purposeful movement, and 6 points for following commands.
What is the range of possible GCS scores?
-The total GCS score ranges from 3 to 15 points, with 3 being the worst possible score (deep coma or death) and 15 being the best possible score (fully conscious).
What does a GCS score between 13 and 15 indicate?
-A GCS score between 13 and 15 indicates a mild head injury.
When should intubation be considered according to the GCS?
-Intubation should be considered when the GCS score is 8 or lower, as it indicates a significant risk to the airway and breathing.
What is the significance of a GCS score of 8 or lower?
-A GCS score of 8 or lower indicates a severe head injury, and it is crucial to consider airway management, such as intubation, to secure the patient's breathing.
Why should the GCS not be used in children without modification?
-The GCS is primarily designed for adults, and for children, a modified version, known as the Pediatric Glasgow Coma Scale, should be used, as the scoring for verbal response differs for children.
