Premedication doses may be lower (e.g., 1-2 mg IV or IM). * **Anesthesia Induction:** Typically 0.1-0.3 mg/kg IV, administered slowly. * **Anesthesia Maintenance:** Continuous infusion (e.g., 0.04-0.2 mg/kg/hour) or intermittent IV boluses. * **ICU Sedation:** Continuous infusion, starting at 0.01-0.1 mg/kg/hour, titrated to achieve target sedation level. Maximum doses are not strictly defined but should be guided by clinical response and adverse effects. * **Status Epilepticus:** For refractory status epilepticus, IV doses of 0.1-0.3 mg/kg (maximum 10 mg) may be given as a bolus, followed by an infusion of 0.05-0.2 mg/kg/hour. ## Pediatric Dosing Dosing in children is highly variable based on age, weight, and clinical condition. * **Procedural Sedation:** * **IV:** 0.01-0.05 mg/kg per dose (maximum 2 mg), may be repeated. * **IM:** 0.05-0.15 mg/kg per dose (maximum 10 mg). * **Intranasal:** 0.2-0.3 mg/kg per nostril (maximum 10 mg total). * **Buccal/Rectal:** Dosing varies significantly by age. * **Anesthesia Induction:** 0.1-0.2 mg/kg IV. * **ICU Sedation:** IV infusion, often starting at 0.05-0.1 mg/kg/hour, titrated. * **Status Epilepticus:** * **IV:** 0.1 mg/kg per dose (maximum 10 mg), may be repeated. * **IM:** 0.15 mg/kg per dose (maximum 10 mg). * **Intranasal:** 0.2 mg/kg per nostril (maximum 10 mg total). * **Buccal/Rectal:** Dosing varies. ## Dose Adjustments * **Hepatic Impairment:** Midazolam is extensively metabolized by the liver; dose reduction is recommended. * **Renal Impairment:** Significant renal impairment may prolong the effects of midazolam; caution and potential dose reduction may be necessary. * **Elderly Patients:** Generally require lower doses due to increased sensitivity and slower metabolism. ## Contraindications * Known hypersensitivity to midazolam or other benzodiazepines. * Acute narrow-angle glaucoma. * Severe respiratory insufficiency. * Acute alcohol intoxication with vital signs depression. ## Adverse Effects Common adverse effects include: * Hypotension * Respiratory depression (including apnea) * Bradycardia * Sedation, somnolence, dizziness * Nausea, vomiting * Hiccups * Paradoxical reactions (e.g., excitement, agitation) * Injection site pain/erythema ## Key Drug Interactions * **CYP3A4 Inhibitors (e.g., azole antifungals, macrolide antibiotics, protease inhibitors, grapefruit juice):** Can significantly increase midazolam plasma concentrations and effects. * **CYP3A4 Inducers (e.g., rifampin, carbamazepine, phenytoin):** Can decrease midazolam plasma concentrations and efficacy. * **Opioids:** Concomitant use increases the risk of sedation, respiratory depression, and death. Use with extreme caution and consider dose reduction of one or both agents. * **Central Nervous System (CNS) Depressants (e.g., alcohol, barbiturates, sedating antihistamines, other benzodiazepines):** Additive CNS depressant effects. ## Monitoring * **Respiratory status:** Closely monitor respiratory rate, oxygen saturation, and for signs of respiratory depression. * **Cardiovascular status:** Monitor heart rate and blood pressure. * **Level of sedation:** Use validated scales (e.g., RASS, Ramsay) to assess depth of sedation. * **Pain:** If used for procedural sedation. ## Clinical Pearls * Midazolam has a rapid onset of action, especially with IV administration. * It has a relatively short duration of action, but its active metabolite can prolong effects, particularly in patients with impaired hepatic or renal function. * Flumazenil is a specific benzodiazepine antagonist that can reverse midazolam's effects, but its use should be reserved for cases of oversedation or overdose. * When used for procedural sedation, titrate slowly to the desired level of effect, avoiding oversedation. * For continuous infusions, consider a "sedation vacation" or daily interruption to reassess the need for sedation and minimize accumulation. *** **Disclaimer:** This information is intended for healthcare professionals and is not a substitute for clinical judgment.
