Randomized Controlled Trial Comparative Study Clinical TrialThe analgesic effect of PCA buprenorphine in Taiwan's gynecologic patients.
The aim of this study was to evaluate the analgesic effect of PCA buprenorphine (intravenous) on postoperative pain in gynecologic patients of Taiwan and the potency ratio of buprenorphine versus morphine, a commonly used potent analgesic. ⋯ We found that PCA buprenorphine (intravenous) could be effective in the treatment of postoperative pain in the gynecologic patients in Taiwan and the potency ratio of buprenorphine versus morphine appeared to be 24:1.

Randomized Controlled Trial Clinical TrialComparison of intravenous retention of fentanyl and lidocaine on local analgesia in propofol injection pain.
With a tourniquet on arm for arresting venous blood flow, we evaluated the efficacy of intravenous (i.v.) retention of fentanyl and lidocaine in reducing the pain on i.v. propofol injection during general anesthesia. ⋯ Intravenous retention of fentanyl 150 micrograms, although less effective than that of lidocaine (p < 0.001), showed local analgesic effect in reducing the pain on propofol injection. The hypothetic mechanisms of action were speculated.
