Panel Discussions

The official papers of the Third World Congress of Anaesthesia­ logy appeared during the Congress at Sao Paulo 1964. All participants appreciated highly the immense editorial work done by the Congress President Dr. Rodriges Alves and the Secretary, Doctor Carlos Parsloe, Hospital Samaritano, Sao Paulo, Brazil. The 10 panels of the World Congress created much interest. Not only the scientific committee, but also many anaesthesiologists all over the world requested that a report of these discussions on re­ markable points of interest be made available. The editors of ‘Anaesthesiology and Resuscitation‘ therefore collected all material available. They want to thank all chairmen and members of the panels for their help and advice, Doctor Carlos Parsloe from Sao Paulo and his colleagues of the Committee for the Third World Congress at Sao Paulo for their valuable assistance, and last not least their publisher for his untiring cooperation.
