简要总结
The purpose of this research is to investigate the non-opioid (non-narcotic) pain-relieving medications clonidine and gabapentin to see if they decrease the amount of opioid pain medications needed after surgery, thereby reducing opioid-related side effects, and time required to return to normal activities of daily living after surgery.
