The number of anesthesia providers required by the Canadian health care system remains controversial. Questions persist regarding both the adequacy of the current supply and what the future demand will be. The purpose of this study was to quantify the number and adequacy of anesthesia providers in 2002, and predict the same for the year 2007. ⋯ This is the first study to survey a national census of "consumers" of anesthetic services: Canadian health care facilities. The results indicate substantial current and worsening future shortages of anesthesia providers in Canada.

The combined use of ultrasound and nerve stimulation for localization of the brachial plexus during infraclavicular block has not been evaluated. We describe three cases of infraclavicular block where we used ultrasound to place the needle and catheter, observe type of muscle twitch obtained and local anesthetic spread after injection. ⋯ Ultrasound guidance during infraclavicular brachial plexus block enables direct visualization of needle/catheter tip location and confirmation of appropriate local anesthetic spread. Our early experience suggests that spread of injectate posterior to the second part of the axillary artery is associated with successful block.
