Randomized Controlled Trial Clinical Trial
The Trendelenburg position increases the spread and accelerates the onset of epidural anesthesia for Cesarean section.
The effect of position on the spread and the onset time of epidural anesthesia has not been well documented. This study was undertaken to assess the effect of modified Trendelenburg position on the spread of epidural anesthesia for Cesarean section. ⋯ This study demonstrates that the modified Trendelenburg position has a significant effect on the spread and the onset time of single shot epidural anesthesia, and can be used safely in term parturients for emergency or elective Cesarean section.

Randomized Controlled Trial Clinical Trial
IM droperidol as premedication attenuates intraoperative hypothermia.
Perioperative hypothermia results largely from core-to-peripheral heat redistribution. Droperidol, which is often used for premedication, promotes vasodilation, and thus may affect redistribution of heat. Accordingly, we tested the hypothesis that preanesthetic droperidol would affect perioperative hypothermia. ⋯ The results of the present study confirm our hypothesis that premedication with droperidol affects perioperative hypothermia. Droperidol may prevent core-to-peripheral heat redistribution after the induction of anesthesia.

To compare hemodynamic changes after tracheal intubation when using a new fibreoptic stylet scope (Styletscope) and a conventional laryngoscope in normotensive and hypertensive patients. ⋯ Tracheal intubation with a stylet scope can attenuate hemodynamic changes and reduce the incidence of sore throat in comparison with the conventional laryngoscope technique in both normotensive and hypertensive patients.

The relationship between autonomic nervous system (ANS) activity and general anesthesia has been explored. Studies have demonstrated partial recovery of heart rate variability (HRV), representative of ANS activity, in the postoperative period, but the arousal period has not been precisely studied. The goals of this study were to analyze modifications of ANS activity during general anesthesia and, more particularly, around the arousal period, to look for predictors of arousal. ⋯ Wavelet analysis of HRV appears to be powerful tool to precisely assess instantaneous changes of HRV during anesthesia. Using this method, there were no identifiable precursory HRV indices of arousal.
