Lidocaine Versus Diphenhydramine to Achieve Local Anesthesia for Laceration Repairs

Diphenhydramine, when injected locally, has been shown to achieve a certain level of local anesthesia. It has been documented for use in simple bedside procedures, however there is a gap in knowledge in its comparison to lidocaine. The purpose of the study is to determine if local infiltration of diphenhydramine is noninferior to the use of lidocaine 1% when trying to achieve local anesthesia for simple laceration repair. Patients who present to the emergency department with a simple laceration will be enrolled in the study. Patients will be evaluated for the pain of the injection as well as the pain of the laceration repair procedure post injection.

Anxiolysis for Laceration Repair in Children

This is a 3-arm adaptive clinical trial to the optimal light sedative for reducing distress during laceration repair in children. The investigators will compare intranasal (IN) dexmedetomidine, IN midazolam, and nitrous oxide (N20). The primary outcome is the Observational Scale of Behavioral Distress - Revised (OSBD-R).

IN Midazolam vs IN Dexmedetomidine vs IN Ketamine During Minimal Procedures in Pediatric ED

Pain in young children has been universally under-recognized due to their inability to describe or localize pain. Improvements in pharmacological interventions are necessary to optimize patient and family experience and allow for successful and efficient procedure completion. This is the first study that will compare three intranasal medications (Intranasal Midazolam, Dexmedetomidine, and Ketamine) to evaluate the length of stay after medication administration along with patient and provider satisfaction. The objective of this study is to demonstrate superior intranasal anxiolysis for pediatric laceration repairs with the shortest emergency department stay and highest patient and provider satisfaction. Based on previous studies and medication pharmacokinetics, we hypothesize that Intranasal Ketamine will have the shortest Emergency Department (ED) stay followed by Midazolam and then Dexmedetomidine with the longest stay; however, Dexmedetomidine will have the highest patient and provider satisfaction followed by Ketamine and then Midazolam.
