Spinal Cord Injury

Acute traumatic spinal cord injury is both a neurological emergency and a perfusion emergency. The initial mechanical insult may be compression, laceration, distraction, or transection; a secondary cascade then evolves over hours to days, with cord ischaemia, oedema, haemorrhage, excitotoxicity, and inflammation extending the original damage. The practical consequence is time sensitivity: preserve oxygenation and spinal cord perfusion, identify ongoing compression, and involve a trauma, neurosurgical, and rehabilitation team early. [2][3] The first blood pressure reading and neurological examination are not isolated facts. They establish the person's baseline and reveal whether the cord injury is changing. A patient with a cervical injury may look stable while diaphragmatic fatigue and secretion retention progress. A person with an injury at or above T6 may have an ordinary-looking heart rate during a dangerous hypertensive episode. The experienced clinician watches the trend, compares findings with the patient's baseline, and treats the mechanism rather than waiting for a dramatic late sign.
