Postoperative Tramadol/Gabapentin/Ibuprofen Versus Tramadol/Placebo/Ibuprofen

A Comparison of Postoperative Tramadol/Gabapentin/Ibuprofen Versus Tramadol/Placebo/Ibuprofen in Children Undergoing Tonsillectomy

To compare the efficacy of scheduled tramadol + PRN ibuprofen/tramadol vs. scheduled tramadol + scheduled gabapentin + PRN ibuprofen/tramadol for pain management during the post-tonsillectomy recovery period. Efficacy will be measured through daily collection of three pain scores (FACES or numeric; 0-10 rating): "pain right now," "typical pain over the past 24 hours," and "worst pain in the past 24 hours." Efficacy will also be measured daily with: 1) the Parents' Postoperative Pain Measure, 2) the number of times "as needed" medication is given by parents, 3) sleep quality, and 4) global satisfaction with pain management and recovery (on day 10 only). All efficacy measures will be recorded in a take-home diary by parents for 10 days postoperatively.

To evaluate the side effects of scheduled tramadol + PRN ibuprofen/tramadol vs. scheduled tramadol + scheduled gabapentin + PRN ibuprofen/tramadol during the post-tonsillectomy recovery period. Safety will be measured through use of a daily take-home diary that the parents fill out, and through phone calls made to parents by the study coordinator every two days during the 10-day recovery period. Specifically, parents will document, on a daily basis, number and occurence of any side effects (e.g., vomiting, dizziness), number of doctor and emergency room visits, length of stay in days (if applicable), and the purpose and location of any medical visits.
