[Experiences with continuous application of sedatives by infusion in patients with regional anaesthesia (author's transl)].

The influence of frequently used sedatives--Diazepam, Flunitrazepam and Benzoctamin--on blood gases in studied in three groups of patients. The application isn't done as bolus injection but continuously by addition of the drugs in 500 ml physiological NaCl-Solution. In the Benzodiazepin groups the lung function is tested by different parameters. The results show no influence on blood gases nor lung function by this method. Therefore, the continuous application has obvious advantages versus bolus injection.
