Needle vs. Knife Part II
In this podcast, I explain why I don’t think needle compression is such a clever idea. Main points are: most people can’t find anterior target, most angiocaths won’t reach, and if used diagnostically you may not be in the pleura leading to an unidentified pneumo or hemothorax. Also, when used diagnostically, if the chest was negative you just caused a pneumothorax.
If you haven’t already, you should listen to Needle vs. Knife Part I with Minh. Also, may of the issues discussed here are also mentioned in the finger thoracostomy episode and the traumatic arrest episode.
Why the standard approach to needle decompression sucks

Michelle Lin did a great blog post about the stuff in this podcast on her Academic Life in EM Blog.
Hot off the press is this swine simulation demonstrating that even when a 14G catheter reached, it may not be sufficient to drain a tension pneumo (Journal of Trauma and Acute Care SurgeryIssue: Volume 73(6), December 2012, p 1410–1415)
