Comparative Study
[Accuracy of target-controlled infusion (TCI) with 2 different propofol formulations].
Target-controlled infusion (TCI) of propofol was initially realized as a device for prefilled syringes (Diprifusor). New TCI systems can be used with any propofol formulation. We compared two different propofol formulations with respect to accuracy of TCI and pharmacokinetics. ⋯ The pharmacokinetic model of Diprifusor can also be used for TCI of Propofol Fresenius. The large volume of distribution in this model may cause an overshoot in concentration.

What are the clinical findings in patients with chronic complex regional pain syndrome (CRPS)? ⋯ In chronic CRPS, among clinical symptoms and signs, pain and sensory impairment play a major role. Mechanical allodynia reveals the highest level of subjective disability among all symptoms. With respect to hemisensory impairment, functional disturbances of central pain processing in the nucleus ventralis posterior of the thalamus are postulated.

The practice of regional anaesthesia in German speaking countries was investigated by a survey. The last part of the trilogy contains the presentation and evaluation of the data about the methods in obstetric anaesthesia. In 2002 questionnaires were mailed to 750 randomly selected departments of anaesthesia, 384 hospitals (51.2%) responded of which 278 had an obstetric unit. ⋯ Pain relief for labour was usually achieved with epidural anaesthesia or drugs. The trend from general to regional anaesthesia for caesarean section is continued, as is the trend from local infiltrative techniques to epidural anaesthesia for vaginal delivery. Switzerland was in the forefront for these developments.

Randomized Controlled Trial Clinical Trial
[Does fentanyl or midazolam improve patient's comfort and cooperation when given for regional catheter placement? A randomized, controlled and double-blind trial].
The procedure of placing a catheter for continuous regional anaesthesia is often associated with fear and pain in the patient. Thus, we evaluated the use of midazolam and fentanyl to improve patient's comfort and cooperation. ⋯ As patient's comfort and cooperation were significantly improved by fentanyl, we recommend fentanyl to facilitate catheter placement for regional anaesthesia.
