The objective of this study is to compare the efficacy of a single pre-operative oral dose of gabapentin 300mg, versus 600mg and placebo in women undergoing Cesarean section. Our hypothesis is that gabapentin 300mg will result in decreased pain scores similar to gabapentin 600mg, but with reduced side effects. We have designed a randomized, double-blind, placebo-controlled study which will aim to answer these questions. Aside from the administration of gabapentin one hour prior to surgery, there are no other changes to the standard protocol of anaesthetic care. Women will be followed up for 48 hours after surgery for assessment of pain scores and overall satisfaction. A further follow-up at three months will determine the incidence of chronic pain.
