Randomized Controlled Trial Comparative Study Clinical Trial
[Postoperative analgesia with tramadol and metamizol. Continual infusion versus patient controlled analgesia].
The study compares the i.v. analgesia of tramadol and dipyrone delivered either as continuous infusion or as patient controlled analgesia (PCA). ⋯ PCA with tramadol and dipyrone can be considered an alternative for postoperative pain management and provided a more individualized treatment approach with lower analgesic consumption and more responders compared to a continuous infusion.

Randomized Controlled Trial Comparative Study Clinical Trial
[Anaesthesia for caesarean section. Comparison of two general anaesthetic regimens and spinal anaesthesia].
The study was undertaken to compare different anaesthetic techniques for scheduled or urgent caesarean section with respect to maternal circulatory parameters, maternal and fetal endocrine stress response, fetal vitality parameters and further clinical parameters such as recovery and analgesic demand. ⋯ When compared with methohexitone, sevoflurane and N(2)O for caesarean section, initial total intravenous anaesthesia with esketamine and methohexitone mediated specific antinociception without negative maternal or fetal effects and not taking invasion kinetics or elimination between uterotomia and cord cutting into consideration. Avoidance of N(2)O allows optimal oxygenation of the fetomaternal unit. Stress protection and hemodynamic responses were well balanced, and intraoperative recall or negative dream reactions were lacking. Superior postoperative pain protection was advantageous after spinal anaesthesia, but in contrast, nausea and vomiting were more frequent in this group.
