Which of the following is a key advantage of using ketamine in acute settings?

The key advantage of using ketamine in acute settings is its rapid onset of sedation. This is particularly important in critical care and emergency situations where swift immobilization or sedation of a patient is necessary to facilitate procedures or manage severe agitation. Ketamine acts quickly, often within minutes, allowing healthcare providers to efficiently address urgent medical needs.

In contrast to other sedatives that may take longer to exert their effects, the speed with which ketamine works makes it a preferred choice in many acute care scenarios. This rapid action can be crucial for patient safety and effective management of emergency situations. Additionally, while ketamine does have a number of side effects, including the potential for hallucinations or dissociative experiences, it is often tolerated and can be managed effectively, which adds to its utility in acute care.
