[Incidence of complications with plexus anaesthesia; a computer-assisted evaluation (author's transl)].

4,042 plexus anaesthesias were analysed for systemic complications by means of computer-assisted data processing. This allowed the large case material to be analysed statistically in great detail. The incidence of complications of this anaesthetic technique and the advantages arising from computer-assisted data processing are reviewed. Specific problems due to technical factors were also investigated.
