Educational Pearls:

  • Estimation of burn size is done by the Lund-Browder diagram and the Rule of 9s – burn size is often underestimated in children because there head is a larger portion of their body and often overestimated in adults.
  • A hyperbaric O2 chamber has been shown to help increase long term cognitive function in people who have CO poisoning from a house fire.

  • Transcranial Dopplers have been around since 80s and are good for following severe brain injuries with serious blood flow abnormalities, but not great for concussions with minor blood flow abnormalities.
  • New study suggests that 83% of concussed vs. non-concussed patients can be followed with the Doppler for their minor blood flow abnormalities.
