Randomized Controlled Trial Comparative Study Clinical Trial
[Influence of gender on propofol consumption and recovery times].
We investigated gender differences of drug consumption and recovery times for propofol-remifentanil anaesthesia. ⋯ With propofol-remifentanil anaesthesia, gender has impact on recovery times and propofol consumption. If the same amounts of propofol are applied, males awake later, with BIS or Narcotrend monitoring males receive less propofol for comparable EEG effects.

Randomized Controlled Trial Clinical Trial
[Influence of blockades with local anesthetics on the stimulation ability of a nerve by peripheral nerve stimulation. Results of a randomized study].
In the present study we examined the influence of local anesthetics on the ability to stimulate a nerve by means of peripheral nerve stimulation. In 35 patients either 5 ml saline (group 1, n=18) or local anesthetics (group 2, n=17) were injected close to the sciatic nerve in a randomized and double-blind manner. ⋯ Therefore nerve damage might occur despite the use of peripheral nerve stimulation. Thus, the multiple injection technique in a close anatomical area has to be considered critically, because anesthetized or partially anesthetized nerves have a lower stimulating ability and could be damaged by a second or third puncture.
