Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Significant controversy exists as to the optimal pain management protocol following pediatric tonsillectomy.8,9 Many studies have examined both pharmacologic and non-pharmacologic modalities to improve pain control in this population. The most common medications prescribed after tonsillectomy include acetaminophen (paracetamol), non-steroidal anti-inflammatory drugs (NSAIDs) (e.g. ibuprofen), and narcotic pain medications, each with a unique mode of action and risk profile.8,10-12 Acetaminophen, which has both peripheral and central anti-nociceptive properties, is generally well-tolerated with low incidence of serious side effects, but may not provide adequate pain control when used at recommended pediatric dosages.13 Narcotic (opioid) pain medications act on the mu opioid receptor and effectively decrease sensory and affective components of pain.14 Unfortunately, opioid pain medications also result in dose-dependent respiratory depression; a significant contraindication in patients with sleep-disordered breathing.15,16 The FDA has released a warning cautioning against the use of codeine, an opioid, for postoperative analgesia following tonsillectomy.7 Furthermore, emerging data suggests that adolescent patients receiving prescription for narcotic pain medication may be at risk for long-term opioid dependence and addiction.17 NSAIDs provide analgesia through reversible COX-1 and COX-2 pathway inhibition which results in decreased prostaglandin-induced inflammation and edema.18 This mechanism of action also interferes with platelet aggregation, potentially impacting bleeding in the postoperative period. Ibuprofen, a derivative of propionic acid, is one of the most commonly prescribed NSAID medications, with a half-life of less than 12 hours.19,20 Pain control in patients receiving NSAIDs is equivalent, or superior to, those receiving acetaminophen alone or in combination with narcotic medication.21-23 In 2011, the American Academy of Pediatrics released its Clinical Practice Guidelines, which stated that ibuprofen can safely be used for postoperative analgesia following tonsillectomy24, a recommendation based on a 2005 Cochrane Review of NSAIDs and post-tonsillectomy bleeding. The most recent Cochrane review on this topic, published in 2012 and based on 15 randomized control trials (RCTs), concludes that there is insufficient evidence available to exclude an increased risk of bleeding with NSAID use following pediatric tonsillectomy.25 This is supported by data from a prospective, randomized control non-inferiority trial conducted at our own institution, in which participants received either ibuprofen or acetaminophen for 9 days following surgery. In this study, an increased rate of post-tonsillectomy bleeding requiring operative intervention could not be excluded because the non-inferiority threshold was crossed. The duration of safe NSAID use, if any, after tonsillectomy is unknown. A study definitively documenting safety and efficacy of short-course NSAID administration following tonsillectomy in children would affect our own standard of care as well as overall clinical practice guidelines.
This study serves as a follow-up clinical trial to a double-blind randomized control non-inferiority trial titled "Postoperative Ibuprofen and the Risk of Bleeding After Tonsillectomy with or without Adenoidectomy" conducted from 2012 to 2016 at Massachusetts Eye and Ear and collaborating institutions. In this study, participants were randomized to receive either ibuprofen (10 mg/kg every 6 hours) or acetaminophen (15 mg/kg every 6 hours) for 9 days following surgery. The non-inferiority margin was set at 3%. Increased type 3 bleeding (bleeding requiring operative intervention) could not be excluded because the non-inferiority threshold was crossed.
In this study, type 3 bleeding occurred in the ibuprofen group on an average postoperative day of 5.95. Additional analyses were conducted on study subjects who discontinued the study drugs prior to postoperative day 9 (the scheduled end point). A total of 50 patients discontinued study medication on or before postoperative day 3. Of these, 21 were randomized to the ibuprofen arm and 0/21 experienced postoperative bleeding events.
A recent systematic review by Tan et al examined commonly used medications following tonsillectomy and efficacy and risks associated with each drug.8 Acetaminophen is commonly used following tonsillectomy given its low side effect profile; however, analgesia is often inadequate at recommended dosages.26 Despite a 2013 FDA warning cautioning against opioid use following pediatric tonsillectomy due to increased risk of respiratory depression, these medications continue to be prescribed following surgery. The majority of tonsillectomies are now performed for sleep apnea and sleep disordered breathing; therefore, a large proportion of patients have increased risk of respiratory compromise and desaturations following surgery when opioid medications are administered.22 Furthermore, emerging data suggests that a significant fraction of adolescent patients receiving opioid pain medications postoperatively may subsequently develop addiction to these medications.17 NSAIDs are effective for post-tonsillectomy analgesia, but concerns remain regarding increased risk of postoperative hemorrhage with use of these medications despite current American Academy of Pediatrics recommendations advocate that ibuprofen may be safely utilized following tonsillectomy in children. Studies to date demonstrate conflicting or equivocal results with regard to increased bleeding risk following NSAID administration. Given previous data from this institution which cannot exclude increased incidence of type 3 bleeding following 9 days of ibuprofen exposure, MEE standard of practice is to recommend against extended duration of ibuprofen use in the postoplerative period. However, given concerns of inadequate analgesia with acetaminophen and respiratory depression and addictive potential with opioid medication, we feel that it is important to assess for postoperative time interval where NSAID medications may be safely administered without increasing incidence of postoperative bleeding events.
We propose a study comparing impact of maximally-dosed ibuprofen (10 mg/kg every 6 hours) versus maximally-dosed acetaminophen (15 mg/kg every 6 hours) on postoperative pain and bleeding when administered for four days (short-course) to children age 2-18 undergoing tonsillectomy with or without adenoidectomy. We believe that a four-day course of medication is appropriate given that the majority of post-tonsillectomy bleeding events occurred on day 6 and the half-life of ibuprofen is such that platelet function returns to baseline within 24 hours of drug discontinuation20. We hypothesize that children aged 2-18 receiving short-course ibuprofen following tonsillectomy will not have increased incidence of bleeding when compared to patients receiving acetaminophen postoperatively. A study definitively documenting safety and efficacy of short-course NSAID administration following tonsillectomy in children would affect our own standard of care as well as overall clinical practice guidelines surrounding this procedure.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Ibuprofen Arm
Ibuprofen
Grape-flavored ibuprofen 100mg/5mL (Leader®) will be dispensed. Ibuprofen will be dosed at 10mg/kg (max dose 600mg) QID (roughly Q6 hours, however we left dosing QID to allow for some flexibility in the dosing schedule to accommodate patient sleeping schedules). The pharmacy will manipulate the volume of each medication using Ora Blend suspension so that for each child, weight-based dosing of each medication will be equivalent in volume. The first dose of study medication will be dispensed 4 hours after the preoperative acetaminophen dose. Thereafter, medication will be dosed QID (or roughly 6 hours apart). Surgeons, nursing staff, and patients and their families will be blinded regarding the type of medication administered.
Acetaminophen
Acetaminophen
Grape-flavored acetaminophen 160mg/5mL (Leader®) will be dispensed based upon the arm to which each participant has been randomized. Acetaminophen at 15mg/kg (max dose 650mg), dosing will be QID (roughly Q6 hours, however we left dosing QID to allow for some flexibility in the dosing schedule to accommodate patient sleeping schedules). The pharmacy will manipulate the volume of each medication using Ora Blend suspension so that for each child, weight-based dosing of each medication will be equivalent in volume. The first dose of study medication will be dispensed 4 hours after the preoperative acetaminophen dose. Thereafter, medication will be dosed QID (or roughly 6 hours apart). Surgeons, nursing staff, and patients and their families will be blinded regarding the type of medication administered.
