Tooth extraction before CABG? why?Register Today!
- by I care there4 I amRN Mar 1, '11Hello,
I am a fairly new telemetry nurse, I have noticed that whenever a pt is going to be going for open heart or CABG surgery they get an xray for mandible series and they have surgery for tooth extraction. I am thinking this is in some way to prevent infection after the surgery but I am not sure. Can anyone please explain? It would be greatly appreciated.:redpinkhe

- Mar 2, '11 by nursej22Streptococcus viridans, an normal oral flora, has a high affinity for endocardium and heart valves. When it enters the bloodstream as a result dental work or periodontal disease it can attack the heart valves resulting in vegetation and erosion as well as septic emboli.
Poor dental hygiene is often the culprit in endocarditis so the bad teeth are often removed prior to valve replacement, otherwise the new valve gets infected too.
And that seldom has a good outcome.

That all just means that the patient would need to have a root canal, or if it was beyond saving, an extraction. When a tooth dies, it becomes interally necrotic and releases these gram-neg. bacteria which circlate throuout the bloodstream, eventually causing growths of bacterial vegetation within the heart.
