So, it's Saturday night and my date for the evening is my ACLS book. I'm going for initial certification, and I'm a new nurse with relatively little experience in the types of situations that ACLS covers (I'm starting on a med surg floor and fortunately, we don't have intubated patients). As I'm going through the material, I'm reading about how narcan, atropine, vasopressin, epi, and lidocaine can be given through the ETT if IV/IO access can't be established. What I'm trying to understand is, wouldn't putting medications into a patient's trachea put them at risk for aspiration or pneumonia? I realize that someone with an ETT and no IV/IO access probably has bigger fish to fry, but I just don't really understand how ETT med administration is done and whether or not it sets patients up for respiratory problems as they recover. Thank you to anyone who can help clear this up for me!
