Objective To investigate the value of noninvasive positive pressure ventilation in patients with high risk of weaning induced pulmonary oedema.Methods From June 2018 to June 2019, 63 patients with mechanical ventilation in the Department of Critical Care Medicine of the First Hospital of Lanzhou University were enrolled. Randomized digital table method was randomly divided into two groups and the resulting random number assignment was hidden in opaque envelopes, the experimental group received non-invasive positive pressure ventilation (n=32), and the control group received mask oxygen therapy ventilation (n=31). The heart rate, respiratory rate, means arterial pressure, hypoxemia, reintubation, blood gas analysis and other indicators were compared between the two groups after 2 hours of weaning. The length of hospital stay, mortality and complications were compared between the two groups.Results After 2 hours of weaning, the heart rate and respiratory rate were significantly lower in the non-invasive positive pressure ventilation group than in the mask group (P<0.05). There was no difference in mean arterial pressure between the two groups of patients, which was not statistically significant (P>0.05). The incidence of hypoxemia, laryngeal edema and reintubation in the noninvasive positive pressure ventilation group was significantly lower than that in the mask group, which was statistically significant (P<0.05), and the blood gas analysis index was better than the mask group (P<0.05). The non-invasive positive pressure ventilation group was significantly shorter than the mask group in the length of hospital stay and intensive care unit (P<0.05). The hospital mortality rate in 28 days was lower than that in the mask group (P<0.05), but there was no difference in tracheotomy, pneumothorax and subcutaneous emphysema between the two groups (P>0.05).Conclusions Noninvasive positive pressure ventilation can effectively prevent hypoxemia, laryngeal edema, and re-intubation in patients at high risk of withdrawal related pulmonary edema. It can also shorten the length of hospital stay, which is worth clinical attention and promotion.
