Question for anesthesiologists- how to manage aspiration pneumonia?

If the fluid was acidic you would expect to see O2 sat decrease, but first probably bronchospasm, coughing, bucking if not paralyzed. If all that was showing it would be wise to cancel and observe. If none of that, the patient was stable O2, pulse, BP, I would probably proceed with the surgery. Then watch the post op course. If stable , the pH was not too low, or it did not actually get into the lungs. If any particulate matter bronchoscopy, flush with saline not H2O. If the patient is stable post op, no apparent sequelae, probably send home with instructions to call back if any sx's. Also depends how reliable the patient is. If particulate matter, probably the pH is not too low.
