There have been many recent advances in the understanding and therapy of respiratory diseases. This review has attempted to cover some of the relevant new information about those disorders most likely to be encountered by anaesthetists. RéSUMé: Il y a de nombreux progrès récents dans la compréhension et la thérapie des maladies respiratoires. Cette revue a tenté de revoir l'information nouvelle et pertinente concernant les maladies les plus susceptibles d'être rencontrées par les anesthésistes.

Multicenter Study Clinical Trial
The Canadian four-centre study of anaesthetic outcomes: I. Description of methods and populations.
The objectives of this study were first to develop and institute a methodology for the study of anaesthetic outcome for parallel use in four teaching hospitals in Canada and second, to compare rates of morbidity and mortality associated with anaesthesia between the four centres. The basic design of the study was occurrence screening with anaesthetists entering data on patient demographics, anaesthetic and surgical factors. Research nurses reviewed anaesthetic records and hospital charts and interviewed patients postoperatively. ⋯ There were major differences found across the hospitals, particularly with regard to volume, patient case-mix, anaesthetic drugs and monitoring used. The use of parallel training, repeated consultations and use of rounds and inservices contributed to the reliability and validity of the data collection. We conclude that outcome surveillance can be instituted in different hospital Departments of Anaesthesia with sufficient confidence to form the basis of comparison of anaesthetic outcome.

Perioperative myocardial ischaemia is common in patients who have or are at risk of coronary artery disease, occurring frequently in the pre-, intra- and postoperative periods. The majority of perioperative ischaemic episodes are silent, being unaccompanied by any symptoms of angina. ⋯ Maintenance of haemodynamic stability is important to reduce the incidence of myocardial ischemia, but ischaemia may occur in the absence of adverse haemodynamic changes. Although our efforts have largely been devoted to the prevention and treatment of intraoperative ischaemia, it is hoped that similar efforts outside the operating room in the postoperative period will further improve patient care and outcome.
