What is the primary use of Ketamine in emergency medicine?

The primary use of Ketamine in emergency medicine is for sedation and pain relief. It is a unique medication known for its dissociative anesthetic properties, which allow it to provide both sedation and analgesia. In emergency situations, Ketamine is especially valuable because it can rapidly induce a trance-like state while preserving airway reflexes and respiratory drive, making it safer to use in patients who might be unstable.

Ketamine is particularly effective in situations such as procedural sedation, where quick and effective sedative and pain-relief properties are essential. Its ability to act quickly and its safety profile make it a preferred choice for various procedures and situations in emergency medical settings. Additionally, it has applications in managing agitation or severe pain, making it multifaceted in its usage during emergencies.

Given its specific properties and applications, the other options do not align with the primary functions that Ketamine serves within the context of emergency medicine.
