decreased aeration and infection?

Long Term Care Columnist / Guide · Apr 17, 2005

Here's a very simple explanation: pain often keeps post-op patients from breathing deeply, but if they don't, the alveoli in the lungs tend to collapse (atelectasis), which causes the mucus produced by the lungs to just sit there, providing a nice warm growth medium for any 'bug' that just happens to be floating by. This is why we get people up and out of bed so soon after surgery, encourage use of incentive spirometers, and make sure they breathe deeply and cough on a regular basis while awake. It's also why we don't just give them Tylenol if they spike a temp (a low-grade fever---under 100 degrees---is fairly usual in the first 24 hours, but we don't want to see higher temps or hear crackles in the lungs at any time after a procedure)........we call the doctor right away.

Hope this helps.

Thanks for responding. I understand the relationship b/t stagnant mucus and bacterial growth, but I thought that the pathogenesis of infection secondary to decreased aeration was different. Thanks for clearing this up.
