Intubation night

The Emergency Medicine Interest Group (EMIG) hosted intubation night on Monday. We were up in the anatomy lab practicing on cadavers how to intubate a patient, which just means sticking a tube down the patient's trachea to start artificial ventilation. I have seen this done many times during my experiences in the ER, so it was especially rewarding to learn the how's and why's of intubation.

The emergency medicine residents taught us how to use an instrument that pushes the tongue out of the way and has a light at the end of it to see down the throat and pull up on the trachea to allow passage of the tube. This is a metal instrument, so it's actually difficult to do without chipping teeth. Then, a small balloon is inflated to secure the tube in place, and the patient is ventilated with an air mask.

If the patient (or in the case, cadaver) was intubated correctly, the chest will rise with ventilation. The tricky part about intubation is getting the tube into the trachea rather than the esophagus. In the ER, the doctors verify that the tube was placed correctly by listening with a stethoscope to breathing sounds in both the chest and stomach: breathing sounds in the stomach indicates that the tube is placed in the esophagus, which is obviously a bad thing. Standard procedure in the ER is also to take a quick x-ray to make sure the tube is placed correctly. If the tube is inserted too far, it could go down the right or left bronchus and supply air to only one lung. That's also an obvious situation to avoid and another reason why doctors listen for breathing sounds on both sides.

I suppose the chances are rather slim that I'll actually be able to do this on a real patient anytime soon, but it's something to look forward to.
