This will be a phase 2, single-center, unblinded randomized controlled pilot trial of two arms comparing opioid-sparing analgesia to the current Boston Children's Hospital institutional practice which has been reported to predominantly include administration of opioids as a first-line analgesic to pediatric patients who present to the emergency department with a diagnosis of acute pancreatitis (AP). This is a pilot trial for which many outcomes have not previously been studied in the pediatric AP population. The focus of this investigation will be to investigate the magnitude and variability of effect sizes for designing a future multi-center, double-blinded randomized controlled trial.
Acute pancreatitis (AP) is the most common pancreatic disease of childhood with an increasing incidence estimated at 13.2 cases in 100,000 children per year. Given the dearth of pediatric literature, most pediatric providers often rely on diagnostic, prognostic and treatment guidelines that have been derived from adults. This is problematic because adult therapeutic guidelines fail to consider the unique age-related responses and requirements of childhood. Pain management is one of the cornerstones in the treatment of pancreatitis, with abdominal pain being the most common presenting symptom of AP. Currently, there are no data on optimal pain management in pediatric AP. Older guidelines suggest that the "use of intravenous patient-controlled analgesia (PCA) is advantageous" as it allows the patient to self-administer opioids and strike a balance between analgesia and side effects. This requires cognitive maturity to understand how to use PCA and poses challenges for younger children, particularly infants and toddlers, as well as pediatric patients with developmental delay. It is particularly concerning that greater than 94% of surveyed pediatric practitioners would use morphine or related opioids as a first-line therapy in children with AP especially when there have been no studies examining the benefits/risks of opioid vs non-opioid analgesics or opioid-sparing therapies in pediatric AP. Furthermore, we recently reported a retrospective analysis demonstrating that opioids are prescribed far more frequently either alone or in combination with non-opioids (70%) than non-opioid alternatives alone (30%). Amongst all types of analgesia prescribed to children who presented to the BCH emergency department (ED) with acute pancreatitis, morphine was the most common. Further research in this area is imperative, particularly given the recent opioid epidemic. From a pediatric perspective, it has been demonstrated that adolescents are amongst those at risk for opioid abuse, thus there is an urgent need to determine whether opioids are necessary for the management of pain in this vulnerable population with AP.

Boston Children's Hospital
Boston, Massachusetts, United States
Efficacy: amount of opioid analgesia (mg/kg/hr) from the time of enrollment until discharge home, transfer to the ICU, or initiation of PCA
The primary endpoint for efficacy is the amount of opioid analgesia (mg/kg/hr) from the time of enrollment until discharge home, transfer to the ICU, or initiation of PCA.
Time frame: time of enrollment through study completion (approximately 5 days), or transfer to the ICU or initiation of PCA
Safety: number of hours from the time of enrollment until discharge home, transfer to the ICU, or initiation of PCA
The secondary endpoint for safety is defined as the total number of incident adverse events, grade 2 or higher, from the time of enrollment until discharge home, transfer to the ICU, or initiation of PCA.
Time frame: time of enrollment through study completion (approximately 5 days), or transfer to the ICU or initiation of PCA
Length of stay
The secondary endpoint for length of stay is defined as the number of hours from the time of enrollment until discharge home, transfer to the ICU, or initiation of PCA.
Time frame: time of enrollment through study completion (approximately 5 days), or transfer to the ICU or initiation of PCA
Time to initiation of oral or enteral diet
The secondary endpoint for time to initiation of oral or enteral diet is defined as the number of hours from the time of enrollment until first oral or enteral intake. The number of hours will be expressed to two decimal places to account for fractions of an hour.
Time frame: time of enrollment through study completion (approximately 5 days), or transfer to the ICU or initiation of PCA
Predefined Feasibility Outcomes to Assess Trial Success
The secondary endpoint for feasibility is defined as (1) ≥80% of eligible patients approached for consent during the trial, and (2) ≥20% of eligible patients randomized into the trial.
Time frame: duration of trial, approximately 1 year from the start of enrollment
Pain resolution: pain scores
To compare pain resolution from time of enrollment throughout hospital stay by comparing pain scores in patients receiving opioid-sparing therapies to those receiving standard of care opioid analgesics.
Time frame: time of enrollment through study completion (approximately 5 days), or transfer to the ICU or initiation of PCA
