Abstract Objective: To evaluate the effect of noninvasive ventilation (NIV) on endotracheal reintubation in patients with hypoxic respiratory failure after abdominal surgery. Methods: The patients with hypoxic respiratory failure within 7 days after abdominal surgery in our hospital ICU were randomly divided into two groups according to the random number table method. The patients were treated with NIV (NIV group, n=173) treatment or standard oxygen treatment (standard oxygen therapy group, n=175). The treatment was performed for 30 days from completion of randomization, or to leave ICU. The endotracheal reintubation rate, noninvasive ventilation time, treatment-related infection and mortality were compared between the two groups. Results: The number of patients endotracheal re-intubated in the NIV group was significantly lower than that in the standard oxygen therapy group [57(32.9%) vs. 80 (45.7%), χ2=5.940, P=0.015]. Compared with the standard oxygen therapy group, the NIV group had no significant improvement in noninvasive ventilation time [(25.5±4.2) d vs. (20.6±3.8) d, t=11.415, P<0.001]. The patients in the NIV group had fewer infections[54(31.2%) vs. 86(49.1%), χ2=11.630, P<0.001]. The patients in group NIV had fewer patients with pneumonia within 7 days [17 (9.8%) vs. 39 (22.3%), χ2=10.002, P=0.002] and 30 days [25 (14.5%) vs. 52 (29.7%), χ2=11.763, P<0.001]. There was no statistically significant difference in ICU hospitalization time between the two groups (P>0.05). Multivariate analysis showed that NIV was negatively correlated with endotracheal reintubation (OR=0.496, 95% CI 0.231~0.817, P=0.007). Conclusion: Noninvasive ventilation can reduce the risk of endotracheal reintubation in patients with hypoxic respiratory failure after abdominal surgery compared with standard oxygen therapy.
