What is the appropriate dose of ketamine for MICA if required every 3-5 minutes?

The appropriate dose of ketamine for MICA (Mobile Intensive Care Ambulance) settings, when requiring administration every 3-5 minutes, is established based on the pharmacokinetics and dosing recommendations for rapid sequence intubation or analgesia. In this context, the correct dose of 20 mg IV/IO allows for effective sedation and analgesia, meeting the clinical needs of patients while minimizing the risk of adverse effects associated with higher doses.

Ketamine is a potent anesthetic and analgesic, and its dosing must be carefully calibrated to ensure the intended effects are achieved without causing excessive sedation or respiratory depression. The chosen dose provides sufficient efficacy while still allowing for repeated administration within a short time frame. This balance is important in emergency settings, where timing and efficacy are critical in managing patient care.

The other doses provided, while they may have their applications in different contexts, do not align with the guidelines established for quick, repeated dosing in MICA settings, as they might either lead to suboptimal effects or increased risk of complications.
