Cricoid pressure

Posted

I was just curious. Is it possible for an anesthetized patient to have vomit forcefull enough that cricoid pressures doesn't work to prevent the vomiting?

No, not if you're doing it correctly. But you can cause an esophagus to rupture.

Cricoid pressure is a way to protect the airway and is not intended to prevent vomiting- it is intended to prevent anything that is vomited from reaching the lungs. We use other methods of trying to prevent vomiting- NPO for 6-8 hours unless condition requires emergent or urgent intervention, using medications to promote gastric emptying. In those emergent/urgent cases, we use rapid sequence intubation and cricoid pressure to reduce the risk of aspiration; that risk is never completely zero.
