What immediate action should be taken for a patient with a deep laceration of the neck?

Applying direct pressure to stop bleeding is crucial for a patient with a deep laceration of the neck because it addresses one of the most immediate threats to life: severe blood loss. A deep laceration can sever blood vessels, leading to rapid hemorrhage. By applying direct pressure, you can help control the bleeding and stabilize the patient until professional medical help arrives.

In addition to blood loss, a neck injury may also affect the airway, making it essential to monitor for signs of airway compromise, but the primary priority is to control bleeding. Covering the wound with an occlusive dressing can be necessary later to protect it from contamination, but direct pressure must be applied first to prevent further blood loss. Leaving the wound open can lead to additional complications and should be avoided.
