This finding is indicative of microatelectasis on the second postoperative day after major abdominal surgery:
ExplanationAtelectasis likely occurs in all patients who undergo general anesthesia, in particular those postabdominal surgeries. Changes of microatelectasis
develop routinely and do not significantly delay discharge for most patients despite the relative state of hypoxia (decreased PaO2
). Deep breathing, use
of an incentive spirometer, early mobilization, and adequate pain control are all measures used to expand lung volumes and promote improved
oxygenation.
