| Scientific title | |
| Study objectives | 1. Gabapentin administration reduces pain and opioid use postoperatively after total hip arthroplasty 2. Preoperative gabapentin is more effective than postoperative administration. This will definitively demonstrate the pre-emptive analgesic properties of gabapentin. |
| Ethics approval(s) | Not provided at time of registration |
| Health condition(s) or problem(s) studied | Pre-emptive pain medication/postoperative pain control |
| Intervention | This is a prospective, randomized, double-blind, placebo-controlled study to compare total morphine consumption between the pre-emptive gabapentin, the postoperative gabapentin and the placebo groups. Patients will be randomly assigned to one of three treatment arms with 30 patients in each arm. Patients who are randomized to the preoperative gabapentin group will receive 600 mg orally (po) prior to surgery. The other two treatment arms will receive either placebo or gabapentin 600 mg 1 hour after their surgery is complete. |
| Intervention type | Drug |
| Phase | Not Applicable |
| Drug / device / biological / vaccine name(s) | Gabapentin |
| Primary outcome measure(s) |
A comparison of the means of morphine consumption among the various treatment groups will be the primary outcome measure. |
| Key secondary outcome measure(s) |
1. Visual Analog Scale (VAS) for pain will be used (0 = no pain, 100 = terrible pain) |
