What is the maximum dose for repeated doses of Ketamine via IM or IN administration?

The maximum dose for repeated doses of Ketamine via intramuscular (IM) or intranasal (IN) administration is indeed four milligrams per kilogram (mg/kg). Ketamine is often used in combat casualty care for its analgesic and anesthetic properties, particularly in a pre-hospital setting. When used for pain management or procedural sedation in tactical environments, monitoring the total dose across multiple administrations becomes critical to avoid potential side effects, particularly excessive sedation or respiratory depression.

Administering up to four mg/kg allows for adequate pain control while balancing safety. This dosing recommendation is founded on studies and clinical practices that outline the effective use of Ketamine in trauma and emergency situations, ensuring that medics can provide safe and effective pain relief while managing the risks associated with its use.
