For which type of procedures is Ketamine particularly indicated?

Ketamine is particularly indicated for short-term procedures requiring intense analgesia due to its unique properties as a dissociative anesthetic. It provides effective pain relief and sedation while allowing for the maintenance of protective airway reflexes, which is crucial in situations where patients need to remain stable and can still breathe independently. This characteristic is especially beneficial in emergency situations or procedures that might provoke significant discomfort or anxiety.

When considering the other options, long-term surgeries often require more sustained anesthetic management, where Ketamine may not be sufficient alone. Routine check-ups and non-invasive diagnostics generally do not necessitate the high levels of sedative or analgesic effects that Ketamine offers, making it less suitable for those contexts.
