Active Comparator: Gabapentin
gabapentin, 20 mg/kg, single dose, 60 min prior to surgery
The active comparator, Gabapentin, is a structural analog of g-aminobutyric acid which has anticonvulsant properties. This study is a prospective randomized double-blinded trial examining the effectiveness of a single dose of liquid Gabapentin given 60 minutes prior to surgery for pain management in pediatric tonsillectomy/adenoidectomy pediatric patients.
Other Name: Neurontin
Placebo Comparator: liquid placebo
subjects randomized to the liquid placebo arm will receive a single dose elixir of 0.4 mL/kg given 60 min prior to surgery
Drug: liquid placebo
Subjects randomized to the liquid placebo will receive an identical appearing liquid placebo of 0.4mL/kg.
This is a randomized, double blind, placebo-controlled trial to study the effect of a preoperative oral dose of gabapentin on postoperative analgesic requirements and subjective pain levels in children undergoing tonsillectomy with adenoidectomy. Investigators will also look for a limited set of genotypic variations to explain any difference between individuals or groups in their response to the medication. Additionally, investigators will document potential adverse effects including excessive sedation, respiratory issues, surgical bleeding and emergence agitation/delirium.
Investigators hypothesize that gabapentin will reduce opioid analgesic requirements and pain scores up to 36 hours post adenotonsillectomy without increased adverse effects such as emergence delirium, respiratory complications or bleeding. The clinical effect may depend on the individual's pharmacogenetic profile to look for a specific set of genetic polymorphisms that relate to the metabolism and effect of the study drug, gabapentin, and opioid analgesic pain medications.
