[Comparison of IVH and oral intake concerning the incidence of postoperative pulmonary complications (PPC)].

We compared IVH with oral intake concerning the incidence of postoperative pulmonary complication (PPC), using PPC score, in which the higher the score, pulmonary function is the worse. PPC score in IVH-group was higher than that in oral-group. Although it has been suspected that, on PPC score, long term IVH-group had the disorder of small airway functioning, the PPC in their group was not always high. In particular, among high score patients whose score was above 12 points in both groups, the PPC in IVH-group (30.4%) was lower than that in oral-group (60.0%). When we use PPC score, we should consider the difference in nutritional intake.
