A Study of Oxygenation During Thoracotomy

A study of oxygenation in 13 patients undergoing thoracotomy is presented. Of these, six were intubated with an endotracheal tube and seven with an endobronchial tube. Marked falls in oxygen tension were found when the pleural cavity was opened, owing to increased shunting in the lungs. Increase in the inspired oxygen concentration is required when the chest is opened, and monitoring of the arterial oxygen tension is desirable when an endobronchial tube is used, as very low oxygen tensions may occur.

Note:

Presented at the first meeting of the Anaesthetists' Academic Association in Kingston, Jamaica, February 1968.
