Today on the podcast, we discuss Midlines. This is the first of two parts. In a week, I will interview Rory Spiegel on the topic, so send me your thoughts and questions in anticipation of that episode.
What the Heck is a Midline?
a 8-25 cm catheter that is placed in the arm and doesn't extend past the shoulder
Why Ultrasound-Guided IVs Suck?
- They aren't long enough 
- Nearly 1/2 of them are dislodged in 24 hrs [Ann Emerg Med 1999;34(6):711]
- Another study demonstrating they do not last [AJEM 2010;28:1]
- Vessel Depth and Catheter Depth are the key to longevity [AJEM 2011 Fields et al.]
- Need 2.75 cm in the vessel for good reliability [https://doi.org/10.1016/j.annemergmed.2019.11.013]
- Midlines are better for avoidance of infections
