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

- Intervention Model Description
- After patient enrollment, a nurse will assign a chronological number from 1 to 90. The pharmacist will randomly divide all 90 subjects into 3 even groups to receive either medication A, B, or C. The pharmacist will dispense the medication in a 1ml syringe to the chronological number provided in the order. The nurse will fill out a mYPAS scale to assess the patient's anxiety level and then administer the medication. After 30 minutes, the physician will determine subject readiness and perform laceration repair. The patient's vitals will be monitored every 5 minutes. At the end of the procedure, both the physician and the parent will answer a question using a Likert scale and the nurse will fill out another mYPAS scale. After the procedure, the patient will be monitored in the ED for any adverse effects and will be discharged home once the patient meets established discharge criteria. The nurse will document the time the patient is discharged.
- Primary Purpose

- Masking
- Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
- Masking Description
- A double blind randomized study. Except for the pharmacist, all treating ED physicians, nurses, patients, patients' caregivers/guardians, ancillary staff, and data analysts will be blinded to the medication administered to the patient. The medication will be dispensed in a 1ml syringe and the barrel of the syringe will be covered by the pharmacist. All the syringes sent from the pharmacy will appear the same, regardless of the volume of the medication.
Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Experimental Intranasal Midazolam |
Dose/Concentration: 5mg/ml of 0.4mg/kg Midazolam (max dose 10mg). Adverse side effects include respiratory depression and hypotension. Intranasal Midazolam is standard of care for minimal procedures in pediatric ED. |
|
|
Experimental Intranasal Dexmedetomidine |
Dose/Concentration: 100mcg/ml of 2mcg/kg Dexmedetomidine (max dose 100mcg). Adverse side effects include Hypotension and Bradycardia at high dosages. IV Dexmedetomidine is FDA approved and widely used in sedation. IN form isn't FDA approved; however, it has been approved to conduct research studies that have showed its efficacy in pre-operative settings, imaging-CT or MRI, dental procedures, and much more. Specifically, in a pediatric ED setting, Neville et al conducted a study comparing intranasal Dexmedetomidine and intranasal Midazolam prior to laceration repair in a pediatric emergency department and showed safe administration of Dexmedetomidine. |

|
Experimental Intranasal Ketamine |
Dose/Concentration: 100mg/ml of 3mg/kg Ketamine (max dose 100mg). Adverse side effect include Laryngospasm. IV Ketamine is FDA approved and widely used in procedural sedation in pediatric EDs. IN form isn't FDA approved in pediatric population; however, it has also been approved to conduct research studies especially in combination with other medications. Gutherie et al conducted a study demonstrating intranasal Ketamine providing safe and successful anxiolysis in pediatric patients in an ED setting. |

Detailed Description
Children commonly present to ED with injuries requiring procedures that can be painful or require a child to be absolutely still. Pain in young children has been universally under-recognized due to their inability to describe or localize pain. Multiple surveys of parents and families have showed that ED satisfaction is highly dependent on the degree of pain a patient experiences and the efforts made to alleviate the pain. Therefore, improvements in pharmacological interventions are necessary to optimize patient and family experience and allow for successful and efficient procedure completion. Intranasal Midazolam is widely used for minimal procedural anxiolysis in pediatric population. Intranasal medication delivery has the highest parent and provider satisfaction with the advantage of avoiding painful needle stick and faster absorption compared to oral or intramuscular medication. Midazolam is a gamma-aminobutyric acid (GABA) receptor agonist that can provide anxiolysis and amnesia but no analgesia. Intranasal Midazolam has a rapid onset of 5-10 minutes with peak at 30 minutes. There have been limited studies evaluating the length of stay or time to discharge after medication administration with an average length of stay of about 30 minutes. It has been shown to be safe and effective in children for minor procedures; however, intranasal Midazolam is notoriously noxious and irritating to nasal mucosa and requires larger volumes for intranasal dosing. Main side effects include respiratory depression and hypotension. It is also known to cause paradoxical reaction with hyperactivity, agitation, and restlessness especially in developmentally delayed or children with Autism or behavioral concerns. Therefore, several new studies have evaluated other newer intranasal medications for minor procedures including intranasal Dexmedetomidine and intranasal Ketamine. Dexmedetomidine is an alpha 2 agonist that mirrors sleep in children and can provide anxiolysis and minimal analgesia. Intranasal dosages that have provided adequate minimal sedation is 2-4mcg/kg (max dosage 100-200mcg) with wide range of onset 10-45 mins with average 30 minutes and peak at 90 minutes. Unlike Midazolam, it preserves airway reflexes without clinically significant hemodynamic instability in children. Studies have also shown that it is well tolerated by children and preferred in children with Autism and behavioral concerns. Ketamine is an N-methyl-D-aspartate (NMDA) antagonist that provides both anxiolysis and analgesia. It is widely used in ED settings for intravenous procedural sedation; however, intranasal route provides non-invasive method of medication administration. Gutherie et al conducted a study demonstrating intranasal Ketamine providing safe and successful anxiolysis and analgesia in pediatric patients in an ED setting. Intranasal dosage of 3-5mg/kg (max dosage 100-200mg) provides optimal onset of action within 10 minutes with peak at 15-20 minutes and duration of 45-60 minutes. It has few significant side effects including the rare laryngospasm and recovery agitation, however, it preserves airway reflexes and favorable in hemodynamic instability. Previous Studies: Limited studies have demonstrated anxiolysis with patient and provider satisfaction or time to discharge after medication administration comparing intranasal Midazolam to intranasal Dexmedetomidine or intranasal Ketamine in a pediatric emergency medicine setting. Neville et al conducted a study comparing intranasal Dexmedetomidine and intranasal Midazolam prior to laceration repair in a pediatric emergency department and concluded that patients who received Dexmedetomidine had less anxiety at the time of positioning for the procedure. Several other studies have demonstrated similar outcomes with better patient and provider satisfaction in pre-operative settings, imaging, and dental settings. Surendar et al is the only study that compared all three intranasal medications. The study included uncooperative pediatric patients in a dental setting. Although overall differences were not statistically significant, the onset of sedation was rapid among Intranasal Ketamine and Midazolam groups but overall success was highest in Dexmedetomidine group. Objective/Aims/Hypothesis: This is the first study that will compare all three intranasal medications 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. The primary outcome will measure the time to discharge after medication administration. Other measurements with include patient's anxiety using previously validated scale Modified Yale Preoperative Anxiety Scale (mYPAS) and physician and parent satisfaction using 5 point Likert scale. Based on previous studies and medication pharmacokinetics, we hypothesize that Ketamine will have the shortest 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.
