Q: Abrupt withdrawal of which of the following intravenous (IV) infusion drug may cause rebound seizures and should be "weaned off" with coverage of other anti-epileptic drugs during management of status epileptics?
Propofol should be weaned off as abrupt withdrawal of propofol may cause rebound seizures due to its very short half life. Coverage should be established with other longer-acting anti-epileptic drug. Lorazepam and Phenobarbital have relative longer half lives and provide good umbrella when short acting propofol is taken off.
Phenytoin and Levetiracetam are not given as IV infusion.
