Study Summary
Tonsillectomy is the most common pediatric surgical procedure performed in the US. The postoperative period can be particularly painful. Codeine (usually in mixed formulation with acetaminophen) is the most commonly prescribed opioid in the US. However, evolving data questions its ability to provide optimal pain relief, while avoiding side effects, especially in the postoperative setting. Tramadol may be a better option for children in the postoperative setting due to its well-documented analgesic properties, low potential for side effects, and excellent safety profile. Seventy-two children scheduled to undergo tonsillectomy (with or without adenoidectomy) at Children's will be invited to participate in a randomized, prospective, double-blinded study to evaluate the efficacy and side effects of codeine with acetaminophen versus tramadol. Using a 10-day take-home diary, caregivers will be asked to record daily information about their child's postoperative pain and other core outcomes and domains as recommended in the recent consensus statement put forth by the Pediatric Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) (McGrath et al., 2008). This study will offer new information regarding the efficacy and side effects associated with tramadol as compared with codeine/acetaminophen (the current practice standard) in a pediatric population. Hypotheses H1: Children who receive scheduled tramadol following tonsillectomy will report better pain control than children who receive scheduled codeine/acetaminophen. H2: Children who receive scheduled tramadol following tonsillectomy will report fewer side effects than children who receive scheduled codeine/acetaminophen.
Primary Outcome
Average number of post-operative days with pain score \>4/10. Pain score assessments were administered once daily by parents using either the Numeric Rating Scale (NRS-11) (with anchors 0=no pain and 10=highest pain imaginable) for children ages 8-15 (von Baeyer et al., 2009) or the Faces Pain Scale-Revised (FPS-R) (with anchors 0=no pain and 10=highest pain imaginable) for children ages 4-10 (Hicks et al., 2001).
Interventions
- DRUG Codeine with acetaminophen
- DRUG Tramadol suspension
