We are now a peer-reviewed blog. It starts today.I have been frustrated (in a good way) by the recent social media discussions (see BoringEM.com) about how social media content is viewed with a skeptical eye by medical educators, academicians, and professionals because of the lack of formal quality-control mechanisms.
Doing well on your Emergency Medicine rotation, whether you are a medical student or resident, will depend in large part on your ability to deliver a coherently concise presentation to the senior resident or attending physician. It’s about telling a story that fits into the construct of how the expert physician thinks.
General principles of fracture reduction involve axially distracting or pulling on a fracture fragment and pushing the piece back into anatomical alignment. This can be seen in the video below (automatically starts at 2:25 for the actual procedure). What if this approach doesn’t work? The fracture fragment remains immobile despite your best efforts.

That was me as a medical student, when I first encountered an undifferentiated patient in moderate distress. The trick is to have a standardized primary and secondary survey approach. Sometimes it takes just a little kick-start to get you thinking and doing.
There has been a lot of discussion on the ideal intravenous fluids (IVF) for resuscitation in the Emergency Department and ICU. This was highlighted by the landmark study in JAMA on ICU patients who received chloride-rich versus chloride-restricted IVFs. This got me to thinking, what exactly comprises the common IVFs that we order? We so often take for granted what’s in 1 liter of normal saline. As it turns out, normal saline is not really “normal”. Dr. Scott Weingart has a great podcast on “chloride poisoning” using IVFs.
This PV card helps remind me what’s in each liter bag of fluids we order (composition of intravenous fluids). At the bottom half of the card is a brief summary of the JAMA findings.

After the posting of this PV card, there was intense discussion about why the D5W osmolarity was 252 mOsm/L instead of 272 mOsm/L, which is found on various medical calculators. See the discussion by Dr. Joel Topf.

Great story.

Has this JAMA study changed your approach to ED intravenous fluid management?
It sure has for me. After 2 liters of normal saline, I consider switching patients to a more chloride-restrictive fluid (we have Plasma-Lyte in our ED). Examples include patients with DKA, AKA, sepsis, and severe dehydration.
