This study is a secondary analysis of another studying looking at hypertonic saline in traumatic brain injury (TBI) making it not the most robust study however it found that TBI patients who’s PaO2 dropped below 100 had a worse outcome than those whose PaO2 did not fall below 100.

 

Bottom line: This is a reminder that traumatic brain injury patients do not do well with hypoxia or hypotension even if transient (during intubation, etc.). Pre-oxygenate and resuscitate prior to intubation and maintain oxygen saturations in the mid-90s for your traumatic brain injured patients.  This applies to prehospital, emergency department, and ICU settings
