We are doing this study to find out if extra medicine is needed to avoid the chance of nausea
sometimes linked to narcotic pain medicine (for example, morphine, dilaudid, fentanyl). Some
doctors always give medicine to prevent the possible side effect of nausea, while others do
not. We are looking to see if this extra medicine is helpful in preventing nausea. The goal
is to screen all patients with pain and enroll enough subjects to reach our goal of 164
evaluable study participants.
