Objective To explore the effect of different duration of prone position ventilation（PPV）on enteral nutritional tolerance in patients with severe pneumonia combined with gastrointestinal dysfunction．Methods A total of 80 patients with severe pneumonia complicated by gastrointestinal dysfunction were treated in the Medical Intensive Care Unit（MICU）of a hospital from July 2020 to July 2023, and were selected as the research subjects．They were divided into the long-duration group（≥12 hours, n=40）and the short-duration group（<12 hours, n=40）according to the daily duration of PPV．The general data, oxygenation index, gastrointestinal function indicators（intra-abdominal pressure, serum gastrin[GAS] and vasoactive intestinal peptide[VIP]）, enteral nutrition achievement rate, and gastrointestinal complications of the two groups were compared．Results The oxygenation index of the short-duration group at 1 d, 3 d,a nd 5 d after treatment（[189.93±33.72], [247.53±63.01], and[325.03±58.11] mmHg, respectively）was significantly higher than that of the long-duration group（[161.63±36.88], [191.83±57.65], and[267.95±46.25] mmHg,respectively, all P<0.05）．The gastric residual volume of the short-duration group（[29.00±7.92], [19.75±4.45], and[11.00±1.87] mL, respectively）was significantly lower than that of the long-duration group（[75.03±23.29], [53.13±11.99], and[21.70±5.52] mL, respectively, all P<0.05）．The intra-abdominal pressure（[8.53±2.05] vs [9.75±2.05] mmHg）and VIP level（[61.14±7.63] vs [67.49±4.43] pg/mL）of the short-duration group after treatment were significantly lower than those of the long-duration group, while the GAS level（[65.02±8.84] vs [54.22±9.21] pg/mL）was significantly higher（all P<0.05）．The total incidence of gastrointestinal complications in the short-duration group（7.50%）was significantly lower than that in the long-duration group（25.00%, P=0.034）．Conclusions For patients with severe pneumonia complicated by gastrointestinal dysfunction, a daily duration of PPV within 12 hours can improve oxygenation and reduce the risk of gastrointestinal complications, which may be related to the reduction of intra-abdominal pressure, regulation of gastrointestinal hormone secretion, and improvement of enteral nutrition tolerance．
