Since venous air embolism may occur during many different types of surgery, management of this clinical emergency can be required in patients who do not have a previously established central venous access for aspiration of air. Recent reviews suggest that management of right heart syndromes in patients with embolism is critical in improving outcome. ⋯ Venous air embolism places an acute load on the right ventricle and may provoke right heart failure, even in the absence of total cardiovascular collapse. Treatment that supports right heart function may allow sufficient time for redistribution of embolized air and produce a good outcome when access for central aspiration of air is not available.

To examine the current role of anesthesiologists in Canadian undergraduate medical education (UME). ⋯ A very small proportion of faculty anesthesiologists participate in Canadian UME at the pre-clerkship level. Considerable variation exists in the amount and format of teaching by anesthesiologists among the Canadian undergraduate curricula, particularly at the pre-clerkship level. However, our results indicate that anesthesiologists are assuming a more important teaching role during clerkship. Our findings may suggest that Canadian medical schools are overlooking the advantages that anesthesiologists offer to UME at the pre-clerkship level, or that many anesthesiologists are reluctant to assume pre-clerkship teaching responsibilities.

Bilateral paravertebral block: a satisfactory alternative for labour analgesia.
To describe a new technique of paravertebral block for labour analgesia and to report the successful use of bilateral paravertebral block in four parturients with contraindications to conventional labour epidural analgesia. ⋯ Bilateral paravertebral block provides adequate analgesia for the first stage of labour and could be an alternative analgesic technique for some parturients with contraindications to conventional labour epidurals.
