[Perioperative anemia and erythropoiesis].

50 consecutive patients with hip arthroplasty had acute normovolaemic haemodilution and intra- and postoperative autotransfusion using Autotrans, Dideco GmbH. 18 of 50 patients received homologous blood products additionally to autotransfusion (Hb less than 8 g/dl, hemodynamic instability). There was no evidence for coagulation disorders, hypoxia or hypovolaemia during the whole investigation period (until the 10th p.

[Effect of particle size and emulsifier on pharmacokinetic values of a parenterally administered fat emulsion].

To evaluate pharmacokinetic data during parenteral application of a fat emulsion a controlled study in healthy volunteers was performed. Another aim of the study was to investigate whether these kinetics could be changed by modification of the emulsion. For this purpose, 10 male medical students--free of any metabolic disorders--received modified batches of one fat emulsion (Lipovenös), differing with respect to particle size or emulsifier.

[Modified neuroleptanalgesia with buprenorphine].

A modification of neuroleptanalgesia by substituting fentanyl with buprenorphine is presented. Both anaesthesia techniques could be applied alternatively. We did not recognize any significant difference between the two groups concerning haemodynamics, the secretion of the so called stress hormones (antidiuretic hormone, cortisol) as well as the postoperative respiratory depression.
