The morphine was injected in the area of the release after application of the tourniquet but before the incision was made. The results demonstrated that patients who received morphine had more pain during the release and did not have less pain postoperatively than patients who did not receive morphine. Also, the patients who received morphine had weakness and hypotension, which Stahl et al. postulated may have been secondary to the systemic effects of morphine.
