Intranasal Lorazepam Versus Intramuscular Paraldehyde in Paediatric Convulsions

This study has been completed.

First received: June 26, 2005
Last updated: July 20, 2006
Last verified: June 2005
The purpose of this study is to evaluate intranasal lorazepam in paediatric status epilepticus. This is a potentially, more effective, safer and cheaper treatment for a common paediatric medical emergency compared to our present first line therapy intramuscular paraldehyde.

Condition Intervention Phase
Status Epilepticus Convulsions Drug: intranasal lorazepam Drug: intramuscular paraldehyde Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Randomised Trial to Compare the Efficacy and Safety of Intranasal Lorazepam and Intramuscular Paraldehyde in the Treatment of Convulsions in Children

Primary Outcome Measures:
  • whether the presenting seizure stopped or not with a single dose of assigned anticonvulsant agent within 10 minutes of administration

Secondary Outcome Measures:
  • time from drug administration to cessation of convulsion
  • frequency of episodes requiring 2 or more anticonvulsant agents
  • continuous blood pressure and oxygen saturation for 30 minutes post drug administration
  • seizure recurrence within 24 hours of cessation of presenting convulsion
  • survival/death

Estimated Enrollment: 156
Study Start Date: July 2004
Estimated Study Completion Date: June 2005
Detailed Description:
The ideal first line anticonvulsant agent would be one that can be safely and easily given at a primary health care facility. It should be quick acting, have minimal cardiorespiratory side effects and have a relatively prolonged effect and be cheap. No combination of drug or delivery system fully satisfies these criteria. There are no large published studies evaluating intranasal lorazepam in paediatric status epilepticus. Given its favourable pharmacokinetics and potential practical advantages, we wished to assess the efficacy and safety of intranasal delivery of lorazepam compared to intramuscular paraldehyde, our existing first line anticonvulsant agent in the treatment of acute seizures in children.
