Objective: This study aims to investigate the effect of oral care via the combined use of colostrum and sodium bicarbonate on the prevention of neonatal ventilator-associated pneumonia (VAP).
Patients and methods: In accordance with the inclusion and exclusion criteria, 120 infant patients who were hospitalized in the neonatal intensive care unit (NICU) from January to October of 2019 were selected and randomly divided into three groups (40 cases in each group), namely, colostrum combined with sodium bicarbonate nursing (experimental group), colostrum (control group I), and sodium bicarbonate (control group II) groups. The primary outcomes measured included incidence rates of VAP and oral infection, positive rate of pathogenic bacteria after sputum culture, mechanical ventilation time, and length of stay (LOS).
Results: The incidence rates of VAP and oral infection and the positive rate of pathogenic bacteria after sputum culture of the experimental group, which were 6.67%, 10.00%, and 10.00%, respectively, were significantly different from those of control groups I and II (p < 0.05). The mechanical ventilation time of the experimental group was 156.07 ± 26.67 h, which was shortened by 9.79% and 9.43% compared with those of control groups I and II, respectively. The LOS of the experimental group was 17.6 ± 1.96 days, which was shortened by 17.74% and 17.50% compared with those of control groups I and II, respectively. The differences were statistically significant (p< 0.05).
Conclusions: Oral care through the combined use of colostrum and sodium bicarbonate can lower the VAP incidence rate of infant patients and shorten their mechanical ventilation time and LOS.
