What is the dosage for Ketamine in altered mental status during unstable SVT?

The appropriate dosage for Ketamine in cases of altered mental status during unstable supraventricular tachycardia (SVT) is 1 mg/kg IV/IO. This dosage is effective for sedation in emergency situations while ensuring rapid onset and adequate control over the patient's condition.

Ketamine is a dissociative anesthetic that provides analgesia and sedation, making it suitable for instances where rapid action is necessary, as in the case of unstable SVT. The intravenous or intraosseous route allows for immediate access to circulation, which is crucial when the patient's mental status is compromised.

While lower doses may not provide sufficient sedation for the procedure or could result in prolonged anxiety or discomfort, higher doses could increase the risk of respiratory depression or cardiovascular effects, particularly in a compromised patient. Therefore, the specific 1 mg/kg dosage maximizes the benefits of ketamine's properties while minimizing potential side effects.

This careful consideration of dosage reflects protocols aimed at maintaining patient safety and effective care during critical interventions.
