ABSTRACT

Objective To study the success rate of ventilator weaning in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients influenced by bobbed endotracheal intubation. Methods One hundred and sixteen AECOPD patients who were given invasive mechanical ventilation and reached the standards of off-ventilator were divided into control group (general endotracheal intubation group) and experiment group bobbed (tracheal intubation) by random digits table method with 58 cases each. The respiratory rate (RR), heart rate (HR), rapid and shallow breathing index (RSBI), oxygenation index (OI), pulse blood oxygen saturation (SpO2), tidal volume and success rate of ventilator weaning were compared. Both groups were implemented of extubation if they reached the standards of the extubation time by observing their ability in spontaneous breathing test (SBT). Results The RR, HR and RSBI before extubation in experiment group were significantly lower than those in control group:(19.7 ± 2.3) times/min vs. (23.5 ± 2.3) times/min, (91.2 ± 6.3) times/min vs. (93.4 ± 8.1) times/min and 80.2 ± 6.7 vs. 90.5 ± 9.6, P<0.05, and the OI, SpO2, tidal volume and success rate of ventilator weaning were significantly higher than those in control group: (269 ± 9) mmHg (1 mmHg = 0.133 kPa) vs. (245 ± 16) mmHg, 0.929 ± 0.014 vs. 0.870 ± 0.037, (6.1 ± 1.2) ml/kg vs. (5.1 ± 0.8) ml/kg and 91.38%(53/58) vs. 77.59%(45/58), P<0.05. Conclusions The bobbed endotracheal intubations can improve the success rate of ventilator weaning in patients with AECOPD.
