Clinical Trial Summary

Headaches in children are very common and are a source of significant distress for the patient and their family. Migraines are the most common headache disorder in children and are associated with episodic pain and other symptoms such as nausea and sensitivity to light and sound that can impair a child's ability to participate in daily activities and lead to missed school or parental missed work. When home treatment fails to relieve symptoms, children often seek care in the emergency department (ED) where a limited number of treatment options exist; while largely effective, these rescue treatments currently all require needle insertion of an intravenous line, take time to administer, result in prolonged ED stays, and have potential unpleasant side effects. In adult patients, a number of studies suggest that lidocaine, a local anesthetic administered intranasally, may provide relief of migraine and migraine-like headache pain in minutes. This approach has the benefit of working quickly, not requiring a needle, and having fewer side effects as the medication acts locally on nerves in the nose. Intranasal lidocaine has not yet been studied in children for this purpose. This study will compare the use of intranasal lidocaine to placebo. The goal of this pilot study is to provide information to inform the sample size calculation for the definitive randomized controlled trial that will aim to measure the efficacy of intranasal lidocaine as an analgesic option for children age 7 years and older who present to the Pediatric ED with a chief complaint of migraine or post traumatic headache with migraine-like features. Secondary objectives will be to report on the frequency and severity of rebound headache between the two treatment groups, adverse events of the study drug, as well as the impact on healthcare utilization measures.The investigators hypothesize that children receiving intranasal lidocaine will have faster and more effective pain recovery compared to children receiving placebo and will be less likely to require the standard therapy for migraine headache. Given very few side effects reported in adult studies and the relatively benign nature of those reported, the investigators do not expect any major safety concerns in the study. It is also hypothesized that intranasal lidocaine will lead to shorter ED visits, thus reducing use of staff and hospital resources and saving money for the healthcare system as a whole.

Study Design


Intervention

Drug:
Lidocaine 2% Injectable Solution
The Barre method of intranasal administration will be used to instil 1mL of lidocaine 2% in either the nostril ipsilateral to the headache or 1ml in each nostril in cases of bilateral headache.
Normal Saline Flush, 0.9% Injectable Solution
The Barre method of intranasal administration will be used to instil 1mL of saline 0.9% in either the nostril ipsilateral to the headache or 1ml in each nostril in cases of bilateral headache.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in migraine pain The primary outcome measure will be the proportion of subjects with numeric pain scores of < 4 out of 10 on a verbal rating scale (range 0 -10 with increasing severity, i.e. 0 = no pain and 10 = most severe pain).Treatment success is defined as a score of 3 or less at the two time points. This will be recorded for each patient during the study timeframe, until study completion. Pain scores will be measured at 30 and 60 minutes post intranasal administration of either the study drug or placebo.
Secondary Rebound headache Proportion of patients with rebound headache (i.e. headache with pain score of greater than or equal to 4 out of 10 on a verbal rating scale; range 0 -10 with increasing severity, i.e. 0 = no pain and 10 = most severe pain). This will be recorded for each patient at the visit of interest during the study timeframe, until study completion. Pain scores will be recorded at 60 minutes, 24 hours, and within 48-72 hours post intranasal therapy.
Secondary Emergency department length of stay Number of hours in the Emergency Department from time of registration to time of discharge or admission to hospital for each subject. The emergency department length of stay will be ascertained from the medical record within 24 hours of the participant's visit.
Secondary Proportion of participants discharged vs. admitted from the emergency department (emergency department disposition) Disposition of the patient from the emergency department for the visit of interest only, i.e. discharge home, hospital admission. This will be recorded for each patient during the study timeframe, until study completion. Disposition will be ascertained from the medical record within 24 hours of the participant's ED visit.
Secondary Proportion of participants with a return visit to the emergency department within 72 hours of discharge. Returns to the emergency department for similar complaints of migraine headache or posttraumatic headache with migraine like features. Within 3 days from index visit.
