From Oct 6th – 8th, 2020, Haney Mallemat (@CriticalCareNow) and his team put on an absolutely amazing online critical care conference called ResusX Rewired.  ResusX is a conference designed by resuscitationists to provide clinicians with the most up to date skills and knowledge to help make a difference in your patients' lives.  Haney and his crew made a combination of short-format, high-yield lectures, and completely customizable small group sessions with procedural demos seem easy.  There were so many high-quality speakers and pearls that I learned from this conference that I wanted to archive them here in one post for reference and to share with our readers/followers.

Background information: There are two popular blade shapes for video laryngoscopy, a standard-geometry blade comparable to a Macintosh blade and a hyperangulated blade. The standard-geometry blade permits both direct and indirect visualization during intubation, whereas the hyperangulated blade permits only indirect visualization. The hyperangulated blade is used with a rigid stylet, whereas the standard-geometry blade allows the use of a bougie if indicated. Proposed benefits of the hyperangulated blade include decreasing the need for head and neck manipulation. Previous research includes an observational study using emergency department data that compared the two blade shapes found no association between blade geometry and first-attempt success rates (Moiser et al.), but this was a single-center study with only 463 patients. Previous unadjusted data from the registry used in the current study by Driver et al. found that standard-geometry video laryngoscopy had a higher first-attempt success rate than video laryngoscopy using the hyperangulated blade (91 percent versus 80 percent, n=1,644) based on data from 2002 through 2012 (Brown et al.).

Background: Patients coming to the ED frequently have several interventions performed in their evaluation and management.  Blood draws, for the most part, are venous. Occasionally, however, arterial sampling is used to gauge acid-base status, PaO2, PaCO2, lactate etc.  This is a painful procedure for patients and can be challenging to perform by the staff.  Although rare, ABGs can cause harm in the form of radial artery spasm, infarct, and/or aneurysms. In non-hypoxemic patients, VBGs are less painful and have been shown to have similar results compared to ABGs [2][3][4][5].

Traditionally, vasopressor infusions have been done through central venous catheters (CVCs) due to the hypothetical risk of extravasation injury to extremities when given through peripheral IVs.  The documented risk of extravasation from peripheral pressors is 3 – 6% [1][3][4][5]. Hypothetically, the extravasation rate can be further reduced.  At Essentials of EM 2020 I gave a short 10-minute talk on 6 pearls I have implemented.  This post will serve as a summary of that talk.

Take Home Points
  • Small to Moderate Size Pneumothorax - consider managing conservatively with observation (need to make sure consulting services on same page)
  • Needle aspiration for spontaneous pneumothorax recommend by British Thoracic and European Respiratory Societies
  • 1 in 5 patients requiring a chest tube will suffer complications - many are iatrogenic in nature. Practice procedure via simulation 
  • Chest tubes placed for traumatic pneumothoraces should get prophylactic antibiotics
  • When deciding on treatment strategy, discuss with your consultants and make sure you have institutional buy-in.
