Physiological changes associated with unilateral pulmonary ventilation during operations on the lung

Summary

No important changes in the respiratory parameters were observed during onelung anaesthesia. However, this kind of thoracic intervention can be accompanied by a dramatic fall in arterial oxygen tension.

Methods to avoid tissue hypoxia have been described. In our series no complications whatever occurred in the operative and post-operative periods which could be related to the oxygenation of the patient.

Résumé

Durant l’anesthésie d’un seul poumon en chirurgie thoracique, il n’y a pas de modifications importantes dans les parametres respiratoires. Cependant ce type de chirurgie thoracique non-cardiaque est accompagné par une baisse marquée dans les tensions artérielles d’oxygène. Nous avons décrit des méthodes pour éviter l’hypoxémie des tissus. Dans notre série, nous n’avons pas eu de complications durant les périodes per et postopératoires en ce qui concerne l’oxygénation du malade.
