An ideal drug as an opiate-sparing analgesic adjunct, acetaminophen, unlike some other drugs, is platelet function sparing, and thus particularly useful in the post-operative orthopedic patient population. In part because of its well established safety profile, as well as minimal drug interactions, acetaminophen is considered a cornerstone of a multimodal analgesic approach. Several studies have described the clinically significant beneficial effects of a multimodal drug approach to analgesia, citing improved pain control and a shorter recovery time. Reduced adverse events and improved pain control with multimodal analgesia drug approaches may result in shorter hospitalizations, improved recovery and function, and reduced health care costs. Opiate therapy, while effective analgesia, is associated with a variety of potential adverse side effects, including pruritus, nausea, emesis, ileus, respiratory depression, tolerance, addiction and sedation. These adverse effects may limit post-operative mobility, postpone return of bowel function, cause feeding intolerance, prolong hospitalization, and postpone post-operative recovery.
While oral acetaminophen is useful as an opiate-sparing therapy, the oral route of drug administration may not be feasible in the early post-operative period. Enteral drug absorption in the initial post-operative period may be erratic, with negative impacts on therapeutic effect. Intravenous acetaminophen may a particularly useful analgesic in these circumstances. At present, there are no pediatric studies in the United States examining the efficacy of multiple- dose IV acetaminophen in the post-operative surgical population. This study will compare analgesic efficacy, nausea and pruritus scores, time to recovery, and length of hospital stay in two subject groups who are status post spine fusion surgery: those who receive schedule IV acetaminophen and opiate for 48 hours, and those who are treated with standard opiate therapy without IV acetaminophen.

Placebo Comparator: Saline Placebo
Control subjects will receive saline as placebo at the time of skin closure intra-operatively and will continue to receive IV saline for 44 hours post-operatively. Doses will be administered every 6 hours (total of 8 doses).
Saline placebo will be given at the time of skin closure intra-operatively and will continue to receive IV saline for 44 hours post-operatively. Doses will be administered every 6 hours (total of 8 doses).
Experimental: Intravenous Acetaminophen
Subjects will receive the first dose of intravenous (IV) acetaminophen (at 15 mg/kg, with maximum doses based on patient age and weight) at the time of skin closure intra-operatively and will continue to receive IV acetaminophen for 42 hours post-operatively. Doses will be administered every 6 hours (total of 8 doses).
Drug: Intravenous Acetaminophen
Scheduled doses of 15 mg/kg of IV acetaminophen will be administered to the treatment arm of the study for a total of 8 doses over a 48 hour period post-operatively.
- Total Opiate Requirement [ Time Frame: 24 hours ]Total opiate requirement was monitored 24 hours post-operatively. Morphine and hydromorphone measurements were totaled and recorded in mg/kg/day of morphine equivalents.
- Average Pain Score [ Time Frame: 24 hours ]Pain Scores were monitored using the numeric pain assessment scale in both treatment arms of the study and recorded and averaged for the first 24 hours after initial intra-operative dose of study drug. The numeric pain assessment scale is a verbal self-reported pain assessment that ranges between 1 (no pain) to 10 (worst pain imaginable).
- Average Nausea Score [ Time Frame: 24 hours ]Nausea scores were recorded by the nursing staff approximately 4 times over the first 24 hours and then averaged for the 24 hour period. Nausea Scores range from 1 (none) to 4 (severe).
- Average Pruritus Score [ Time Frame: 24 hours ]Pruritus scores were recorded by the nursing staff approximately 4 times over the first 24 hours and then averaged for the 24 hour period. Pruritus scores range from 1 (none) to 3 (intolerable).
