Randomized Controlled Trial Comparative Study Clinical TrialIntermittent bolus versus patient-controlled epidural morphine for postoperative analgesia.
Patient-controlled epidural analgesia (PCEA) is a technique that combines the flexibility and convenience of PCA with the intrinsic analgesic efficacy of epidurally administered opioids. The aim of this study is to compare the analgesic and side effects of intermittent bolus injections of epidural morphine with PCEA using morphine during the first 24 h after elective low abdominal surgery. ⋯ PCEA with morphine decreases morphine consumption and with less adverse effects than intermittent bolus of epidural morphine. PCEA with morphine is an acceptable alternative to epidural morphine after low abdominal surgery.

Case ReportsTruncal rigidity as a result of epidural sufentanil--a case report.
It is well known that intravenous opioids may cause truncal rigidity. To the best of our knowledge truncal rigidity induced by epidural opioid has never been reported. Recently, we came across an accident of truncal rigidity following epidural sufentanil. ⋯ She stayed in the recovery room for 24 h and returned to ward in satisfactory condition. The incidence disclosed that epidural sufentanil even with a dose as small as 50 micrograms could cause truncal rigidity. Thus when epidural sufentanil is applied for post-operative pain control constant vigilance is necessary in order to avoid accident.

Comparative StudyPrediction of bleeding diathesis in patients undergoing cardiopulmonary bypass during cardiac surgery: viscoelastic measures versus routine coagulation test.
Severe hemorrhagic tendency often complicates cardiopulmonary bypass (CPB) in cardiac surgery. In this study, we compared the effectiveness of thromboelastography (TEG), Sonoclot (SCT), and routine coagulation test (RCT) in the prediction of coagulation defects. ⋯ Our data demonstrated that the TEG monitoring is a useful tool for detecting post-CPB bleeding diathesis and can provide much predictive information. RCT and SCT are of limited value because of higher rate of unreliable results.

Intravenous infusion of low dose propofol for conscious sedation in cesarean section before spinal anesthesia.
Conscious sedation, not affecting the safety of both mother and fetus, is especially favorable in anxious patients undergoing Cesarean delivery. However, when sedation is started before performing intrathecal anesthesia, the infusion time before delivery will be prolonged. In this study, the incidence of maternal and fetal complications under propofol infusion were evaluated as well as the blood concentrations of propofol during delivery at different time of sedation. ⋯ Conscious sedation by low dose propofol infusion is safe for both mother and fetus in spite of longer infusion time.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of epidural butorphanol plus clonidine with butorphanol alone for postoperative pain relief.
Epidural butorphanol has been shown to produce effective analgesia with less side effects than that of morphine but relatively short duration. Clonidine, an alpha 2-adrenergic agonist, has been reported to provide [corrected] pain relief by epidural administration. Furthermore, epidural clonidine has been shown to potentiate the analgesic effect of epidural morphine. The present study was undertaken to evaluate the analgesic and side effects of epidural administration (Ep) of butorphanol and clonidine. ⋯ Our study showed that the addition of clonidine to epidural butorphanol did not enhance its analgesic effect in any significant manner nor did it reduce the adverse effects. This combination does not seem to offer any advantage for clinical use.
