Dexmedetomidine

Dexmedetomidine is a relatively selective alpha-2 adrenergic receptor agonist. It possesses sedative, anxiolytic, and some analgesic properties, uniquely providing 'cooperative sedation' where patients remain easily arousable and interactive. It is primarily administered intravenously in critical care and anesthesia settings, and does not typically cause respiratory depression at clinical doses.

Dosage by Body Weight

Must be administered only by healthcare professionals skilled in the management of patients in intensive care or outpatient sedation settings. Dosage is highly individualized and titrated to clinical effect. Typically initiated with a loading infusion (optional) followed by a continuous maintenance infusion calculated in micrograms per kilogram of body weight (mcg/kg/hr).

  1. Body Weight
    Below 5 kg
    Dose
    0.05 to 0.2 mcg/kg/hour continuous infusion
    Frequency
    Continuous IV infusion
    Tracking Notes
    Not routinely recommended in neonates. Use with extreme caution under strict ICU supervision. High risk of bradycardia.
  2. Body Weight
    5-7 kg
    Dose
    0.2 to 0.7 mcg/kg/hour continuous infusion
    Frequency
    Continuous IV infusion
    Tracking Notes
    Titrate slowly in increments of 0.1 mcg/kg/hr. Monitor hemodynamics closely.
  3. Body Weight
    8-10 kg
    Dose
    0.2 to 1.0 mcg/kg/hour continuous infusion
    Frequency
    Continuous IV infusion
    Tracking Notes
    Avoid rapid bolus loading doses in pediatric patients to minimize the risk of transient hypertension.
  4. Body Weight
    11-15 kg
    Dose
    0.2 to 1.4 mcg/kg/hour continuous infusion
    Frequency
    Continuous IV infusion
    Tracking Notes
    Titrate to achieve desired level of sedation. Ensure continuous cardiac and respiratory monitoring.
  5. Body Weight
    16-20 kg
    Dose
    0.2 to 1.4 mcg/kg/hour continuous infusion
    Frequency
    Continuous IV infusion
    Tracking Notes
    Assess patient arousal and pain level regularly. Adjust dose dynamically to reduce prolonged sedation.
