Abstract:

Objective　To investigate the clinical effect of fiberoptic bronchoscope（FOB）-assisted nasogastric tube positioning in chronic obstructive pulmonary disease（COPD）patients with mechanical ventilation.    Methods    40 mechanically ventilated COPD patients, enrolled from March 2014 to October 2016, were randomly divided into 20 patients（test group）with FOB-assisted nasogastric tube positioning and 20 patients（control group）with routine indwelling nasogastric tube.    Results    The indexes, including the first-attempt success cases, the first-attempt success rates, intubation time, number of complications, were significantly better in the test group as compared with the control group， which was opposite case for expenses (19 vs 9, 95.0 vs 47.3, (8.37±1.34) vs (17.9±3.80), 4 vs 12, (262±0) vs (12±0), P<0.05). There were no statistical differences in heart rate, systolic blood pressure, diastolic blood pressure, pulse oxygen saturation, arterial PaO2 and arterial PaCO2 between before and after indwelling nasogastric tube in the test group ((87.7±13.5) vs (89.9±13.8), (114.35±10.6) vs (115.1±9.2), (67.4±14.0) vs (68.7±9.9), (96.9±2.3) vs（97.2±2.2), (88.5±2.2) vs（82.0±19.2), (45.9±18.0) vs (38.4±2.6), P>0.05).   Conclusion    If the routine method is difficult in COPD patients with mechanical ventilation, it should be replaced by FOB-assisted operation because it is simple , quick, safe and reliable. Furthermore, slight injury can be incurred and high success rate can be achieved.
