A comprehensive clinical examination is the basis for selecting further diagnostic steps:
- Assessment of consciousness using the Glasgow Coma Score (GCS).
- General physical examination-including blood pressure, heart rate, body temperature, respiratory rate, cyanosis (purplish to bluish discoloration of the skin, mucous membranes, lips, and fingernails), level of consciousness, organ-related symptoms, or focus search (focal search)
- Auscultation (listening) of the heart.
- Auscultation of the lungs
- Palpation (palpation) of the abdomen (abdomen) (tenderness?, knocking pain?, coughing pain?, defensive tension?, hernial orifices?, kidney bearing knocking pain?)
- Neurologic examination [meningeal signs (meningismus; opisthotonus/severe spasm of extensor muscles of neck)]
Glasgow Coma Scale (GCS) – scale for estimating a disorder of consciousness.
| Criterion | Score | |
| Eye opening | spontaneous | 4 |
| on request | 3 | |
| on pain stimulus | 2 | |
| no reaction | 1 | |
| Verbal communication | conversational, oriented | 5 |
| conversational, disoriented (confused) | 4 | |
| incoherent words | 3 | |
| unintelligible sounds | 2 | |
| no verbal reaction | 1 | |
| Motor response | Follows prompts | 6 |
| Targeted pain defense | 5 | |
| untargeted pain defense | 4 | |
| on pain stimulus flexion synergisms | 3 | |
| on pain stimulus stretching synergisms | 2 | |
| No response to pain stimulus | 1 |
Assessment
- Points are awarded for each category separately and then added together. The maximum score is 15, the minimum 3 points.
- If the score is 8 or less, a very severe brain dysfunction is assumed and the there is a risk of life-threatening respiratory disorders.
- With a GCS ≤ 8, securing the airway by endotracheal intubation (insertion of a tube (hollow probe) through the mouth or nose between the vocal folds of the larynx into the trachea) must be considered.
