Comparative Study
Current practice in regional anaesthesia in Germany.
Several new techniques and agents (e.g. ropivacaine) have been introduced in regional anaesthesia to improve patients outcome and safety. The beneficial effects on patient outcome are clear with these techniques, however, no information is available about their pattern and frequency of use in clinical practice. This study presents data concerning the current practice of regional anaesthesia in Germany. ⋯ In small hospitals a majority of board certified anaesthesiologists rely on basic regional anaesthesia techniques. In large departments some consultants provide the entire spectrum of regional anaesthesia, with the majority of cases transferred to the residents responsibility. These results indicate the strong need to improve residency programs with regard to regional anaesthesia.

To assess the knowledge, beliefs and attitudes of anaesthesia providers on the patients' possible intraoperative visual experiences during cataract surgery under local anaesthesia. ⋯ The majority of anaesthesia providers in the USA, UK and Singapore are aware that patients may experience a variety of visual sensations during cataract surgery under regional or topical anaesthesia. Those who have previously managed patients undergoing cataract surgery under topical anaesthesia are more likely to believe this compared to those who have not.

Comparative Study
Inter-patient variability upon induction with sevoflurane estimated by the time to reach predefined end-points of depth of anaesthesia.
A difficult issue in anaesthesia is its titration for an individual patient to avoid over- and underdosage. Common practice is to use an initial dose and increase it subsequently if the defined end-point is not reached. This assumes that the end-point is reached after a similar interval of time in all patients given a similar dose. In order to test this hypothesis we measured the time to reach end-points such as loss of consciousness (LOC), a bispectral index (BIS) value of 60, the minimal BIS and the minimal mean arterial pressure (MAP) values. ⋯ These results demonstrate large inter-patient variability for the time necessary to reach defined end-points of depth of anaesthesia when a similar dose of anaesthetic is given. Measuring the time to reach a predefined BIS value would allow application of nociceptive stimuli only at adequate levels of hypnosis and would facilitate titration.
