Detailed Description
Obstructive sleep apnea (OSA) as an indication for adenotonsillectomy has increased significantly over the past ten years, and now has surpassed recurrent tonsillitis as the most common indication for this procedure. Opioids continue to be the most commonly administered pain medication for these procedures. Studies have shown that patients with OSA have significantly increased sensitivity to opioids that results in post-operative respiratory depression and apnea when administered via standard opioid dosing protocols. Children with OSA were shown to have a nearly fivefold increase in the odds of developing respiratory complications when compared to their counterparts with tonsillitis. Ketorolac possesses similar efficacy to morphine without the problematic complications of respiratory depression, nausea and vomiting, which are commonly seen post-adenotonsillectomy. Importantly, when combined with opioids, ketorolac is opioid-sparing. This synergistic effect means that a similar level of analgesia is achieved using a lower dose of opioid. However, there continues to be concern about using ketorolac due to the potential risk of post-operative bleeding from anti-platelet activity.
This randomized, prospective study aims to determine the effect of ketorolac on the total dose of morphine required to achieve postoperative analgesia in children with OSA undergoing adenotonsillectomy. Participants will be randomly assigned to receive ketorolac or to not receive ketorolac. The post-anesthesia care unit (PACU) nurses, who will be blinded to ketorolac administration, will evaluate the patients using the Face, Legs, Activity, Cry, Consolability (FLACC) scale scores at 10 minutes post-op, 20 minutes post-op and at time of PACU discharge. For patients with a FLACC score of 6-10, morphine (0.05mg/kg) will be administered. For patients with FLACC scores of 3-5, morphine (0.025mg/kg) will be administered. The total amount of opioid required to obtain a FLACC score of less than 3 will be evaluated as the primary outcome. The secondary outcomes to be evaluated will be PACU FLACC scores, time required in PACU, incidence of post-tonsillectomy bleeding and total pain medications administered during hospital admission.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Ketorolac
Participants randomized to the ketorolac group will receive 0.5mg/kg IV at the end of the adenotonsillectomy procedure, once hemostasis has been achieved
|
Patients in this group will receive 0.5mg/kg of ketorolac, administered intravenously.
Other Names:
All patients will undergo inhalational induction with nitrous oxide and sevoflurane. After intravenous (IV) placement, 1-3mg/kg of propofol and 1mcg/kg of fentanyl will be administered. After induction, 0.5mg/kg of dexamethasone and an IV infusion of 15mg/kg of acetaminophen will be administered. During surgery, 0.5mcg/kg of dexmedetomidine and 0.1mg/kg ondansetron will be given. A rescue dose of 0.5-1mcg/kg of IV Fentanyl will be available for use at the end of the procedure. The decision to administer will be left to the discretion of the attending anesthesiologist. The choice to give this will be made based on variables including patient's condition and a 20% increase in the heart rate and blood pressure. The PACU nurses, who will be blinded to ketorolac administration, will evaluate the patients using FLACC scores. For patients with a FLACC score of 6-10, morphine 0.05mg/kg will be administered. For patients with FLACC scores of 3-5, morphine 0.025mg/kg will be administered.

|
The total postoperative morphine dosage required to achieve analgesia (defined as a Face, Legs, Activity, Cry, Consolability (FLACC) Scale score of less than 3) in children with obstructive sleep apnea undergoing adenotonsillectomy will be compared between study arms to examine the effect of ketorolac administration.

Post-Anesthesia Care Unit (PACU) nurses will evaluate the patients using Face, Legs, Activity, Cry, Consolability (FLACC) Scale scores at 10 minutes post-op, 20 minutes post-op and at time of PACU discharge.
Each category is scored as 0 (no indication of pain), 1 (indication of moderate pain), or 2 (visibly experiencing severe pain).
Total scores range from 0 to 10, with higher scores indicating more pain.
