Patients in the gabapentin group will receive gabapentin preoperatively, one time dose of 10 mg/kg PO (maximum dose 600 mg) and will resume scheduled doses postoperatively of PO gabapentin, 300 mg PO every 8 hours, in addition to acetaminophen and ibuprofen for 7 days postoperative. Acetaminophen 15mg/kg PO (max 1 gm) every 4-6 hours as needed for pain, max dose 4 gm per day; Ibuprofen 4-10 mg/kg PO divided over 8 hours as needed for pain, max dose 40 mg/kg/day; gabapentin, 10 mg/kg standing every 8 hours (22).

Patients in the hydrocodone group will receive scheduled doses of hydrocodone, acetaminophen and ibuprofen at scheduled doses. Acetaminophen 15mg/kg (max 1 gm) every 4-6 hours as needed for pain, max dose 4 gm per day; Ibuprofen 4-10 mg/kg PO divided over 8 hours as needed for pain, max dose 40 mg/kg/day; hydrocodone acetaminophen solution 7.5mg-325mg/15mL 5mL for ages 12-14yrs and 10 mL for ages 15-18yrs, q 4-6 hours as needed for pain.

The primary outcome variable will be the total opioid equivalent dose recorded over two weeks. The proposed study will test the null hypothesis that the two population (gabapentin and placebo) means are equal. The criterion for significance (alpha) has been set at 0.050. The test is 2-tailed, which means that an effect in either direction will be interpreted.
