Clinical Trial Summary

The purpose of this study is to compare IV acetaminophen to oral acetaminophen for pain control in children undergoing tonsillectomy with or without adenoidectomy.


Description:

Tonsillectomy with or without adenoidectomy is a common surgical procedure in children and adolescents. Usually performed for recurrent tonsillitis or symptoms of airway obstruction, the procedure can result in significant post-operative pain. Common analgesic techniques include the use of oral acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen by mouth (PO) or ketorolac intravenous (IV), and narcotics. Acetaminophen has been shown to be effective in reducing pain and post-operative opioid requirements. Its administration can be oral, rectal, or intravenous. NSAIDs, though effective for pain control, have been shown to increase bleeding risk and disrupt hemostasis. Narcotics are effective for pain control but increase the risk of nausea and vomiting. They also have the potential to cause respiratory depression.

IV acetaminophen (OFIRMEV) is indicated for management of mild to moderate pain, and as an adjunct to opioids for severe pain. Several studies have examined the efficacy of IV acetaminophen vs placebo and/or active controls (meperidine, rectal acetaminophen (PR), tramadol). IV acetaminophen has been shown to be superior to placebo for pain control. Though there is data regarding peak plasma and Cerebral Spinal Fluid (CSF) concentration of acetaminophen when given by different routes (PO vs IV vs PR), there is no data comparing the efficacy of oral vs IV administration for pain control post-tonsillectomy in children.

Outcome

Type Measure Description Time frame Safety issue
Primary Total Pain Medication All pain medication documented during the first 24 hours postoperatively, in mg morphine equivalents. From time of PACU admission until 24 hours post-operatively.
Secondary FLACC: Face, Legs, Activity, Cry & Consolability (FLACC) Pain Assessment Scores FLACC: Face, Legs, Activity, Cry, and Consolability Pain Assessment Scale (FLACC), a five-item, three point scale that measures each of 5 pain behaviors on a scale of 0 - 2 which are summed to result in a total score of 0 - 10. Clinical judgment is used to interpret pain. The higher the score on the FLACC correlates with a higher pain score (0= no behaviors indicative of pain and 10= five behaviors indicative of significant pain). This scale was evaluated by blinded post-operative anesthesia care unit (PACU) Registered Nurses (RNs) at admission to PACU. At time of admission into PACU.
Secondary Incidence of Post-operative Vomiting Percentage of subjects with at least one episode of post-operative vomiting From admission into PACU until 24 hours post-hospital discharge. At the conclusion of enrollment, this measure will be assessed for all participants.
Secondary Parental Satisfaction With Pain Control. Parental satisfaction with pain control, as measured on a 10 point Likert scale where 1= Extremely dissatisfied and 10= Extremely satisfied. Data gathered through phone call to parents 24 hours post hospital discharge. 24 hours post hospital discharge.
