Brief Summary:
The trial (Intranasal ketamine for procedural sedation in children: a randomized controlled non-inferiority multicenter trial or INK; ReDA 5496; CTO 1545) is being scheduled for launch in Spring 2019. Due to the possibility of failure of the experimental intervention (intranasal ketamine 10 mg/kg), the data safety monitoring board (DSMB) and statistical methods team would like to explore the possibility of developing a stopping rule to prevent patients from being enrolled in a futile trial and conserve resources. In order to get accurate data to develop a statistically robust stopping rule, it is necessary to conduct a cohort study of patients that receive the INK trial's experimental intervention and according to it's protocol. This cohort study will help estimate the chance of adequate sedation and inform the final dosing protocol for the INK trial.
Detailed Description:
Between 20 and 40% of extremity fractures in children require a closed reduction, often necessitating procedural sedation and analgesia (PSA) (3, 4). Intravenous (IV) ketamine is the most commonly used sedative agent used to perform a closed reduction (5). However, children rate IV insertion as the most painful hospital experience, second only to the injury itself (6). Intranasal (IN) ketamine may provide effective sedation for children undergoing a closed reduction without the distress and pain related to IV insertion. Although the proportion of children with adequate sedation using IN ketamine at doses of 9-10 mg/kg has been reported to be at least 75% (9-11), there is the possibility of inadequate sedation because IN ketamine 10 mg/kg has not been used for procedural sedation for fracture reduction. A multi-centre, two-arm, randomized, blinded, controlled, non-inferiority trial designed to test the hypothesis that intranasal (IN) ketamine is non-inferior to intravenous (IV) ketamine is being planned for launch in Spring 2019 and a stopping rule for futility will ensure that patients are not unduly enrolled and that resources are not wasted in a futile trial. Creating of a methodologically rigorous stopping rule depends on the results of a small cohort study to provide a more accurate and informed estimate of the probability of adequate sedation with IN ketamine 10 mg/kg.
