Case ReportsVentricular tachycardia after oxytocin injection in patients with prolonged Q-T interval syndrome--report of two cases.
Oxytocin is widely used in obstetric settings to stimulate uterine contraction and prevent postpartum hemorrhage. Its adverse effects which include transient hypotension and increase heart rate could be life-threatening in patients with fixed cardiac output or hypotension resulting from hemorrhage. We reported two cases suspected to have preexisting prolonged Q-T interval syndrome (PQTS) who developed ventricular tachycardia immediately after intravenous injection of oxytocin. Anesthetic management of and use of oxytocic agents in patients with PQTS were discussed.

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.

Patient barriers to cancer pain management: from the viewpoint of the cancer patients receiving analgesics in a teaching hospital of Taiwan.
The purpose of this study was to investigate the barriers to receiving analgesics for cancer pain in Taiwanese patients. ⋯ Overall the result revealed that pain management in these cancer patients was inadequate. Misconceptions on the part of patients still exist. Educational intervention could be an effective means for overcoming such barriers in Taiwanese patients who received analgesics for cancer pain.

The efficacy of intrathecal coadministration of morphine and bupivacaine for labor analgesia.
Intrathecal (i.t.) opioids can provide labor analgesia, but the onset of pain relief is slow. Bupivacaine has the beneficial property of less motor blockade than other local anesthetics. This study retrospectively examined the efficacy of concomitant use of i.t. morphine and bupivacaine for labor pain relief. ⋯ Our results showed that a single injection of i.t. morphine and bupivacaine provided rapid onset and effective analgesia with manageable side effects and without major complications. Thus, i.t. morphine and bupivacaine provides an alternative to epidural analgesia for most women in labor.
