Application and nursing care of fiberoptic bronchoscopy in mechanical ventilation of patients with acute respiratory distress syndrome

Abstract

Objective To investigate the application and nursing of fiberoptic bronchoscopy in mechanical ventilation of patients with acute respiratory distress syndrome. Methods 63 patients with acute respiratory distress syndrome who were treated with mechanical ventilation were randomly divided into control group (n=32) and observation group (n=31). The patients in each group were treated with mechanical ventilation and western medicine.The control group was given routine nursing and suctioning.The observation group was treated with fiberoptic bronchoscopy and high quality nursing.The treatment period was 7 days.The changes of blood oxygen saturation (SpO2), arterial blood carbon dioxide partial pressure (PaCO2) and oxygenation index (PaO2/FiO2), the time of mechanical ventilation, the number of cases of ventilator-associated pneumonia (VAP), the number of successful cases of weaning, and the 28-day mortality were observed.The curative effect of the two groups was observed. Results Before treatment, the SpO2, PaCO2, PaO2/FiO2 between the two groups had no statistically significant differences(all P>0.05). After treatment, the SpO2 of the two groups increased [(94.7±3.4)% in the observation group, (90.5±3.0)% in the control group], and the PaCO2 reduced[the observation group (46.1±3.9)mmHg, the control group (52.2±3.4)mmHg], PaO2/FiO2 increased[observation group (222.9±13.6)mmHg, control group (182.2±16.7)mmHg], which of the observation group were better than the control group(t=5.203, 6.624, 10.587, all P<0.01). The time of mechanical ventilation, the number of VAP cases, the number of successful cases of weaning, 28-day mortality in the observation group were (10.2±2.9)d, 2 cases, 24 cases and 22.58%, which were better than those in the control group, the differences were statistically significant (t=6.325, χ2=4.057, 5.10, 4.089, all P<0.05). The total effective rate in the observation group was 77.42%, which was significantly higher than 53.13% in the control group (χ2=4.089, P<0.05). Conclusion Application of fiber bronchoscopy and quality care in the mechanical ventilation of patients with acute respiratory distress syndrome has good effect, it is worthy of clinical promotion.
