What is the maximum IV/IO dose of Diazepam for post-intubation sedation?

• A. 5 mg
• B. 10 mg
• C. 15 mg
• D. 20 mg

Answer: (A)

Diazepam as IV/IO for post-intubation sedation is dosed conservatively to prevent oversedation and respiratory or hemodynamic depression. Its long half-life and active metabolites mean even a moderate dose can cause prolonged sedation, making recovery and ongoing monitoring harder in the intubated patient. Therefore the per-dose maximum is 5 mg, which provides some sedative effect without the high risk of apnea, hypotension, or extended sedation seen with higher single doses. If more sedation is truly needed, other agents or additional, carefully spaced dosing should be considered rather than increasing a single diazepam dose. Higher per-dose amounts (10 mg or more) would markedly raise the risk of prolonged sedation and adverse effects.
