Abstract:
Objective On patients with mechanical ventilation spontaneous breathing trial (SBT) success, out of breath machine smoothly pulled out after endotracheal intubation for active airway moist sequential therapy of clinical new method and new technology. Methods Between January 2013 and May 2014 respiratory endotracheal intubation implementation of mechanical ventilation with intensive medicine successful withdraw machine pulled out of 135 patients with tracheal intubation, they were divided into group A(68 cases) and group B(67 cases) by random digits table method. The patients in group A were treated with buoy type oxygen device, group B with active airway moist heat treatment unit. The breathing rate, PaO2, SpO2, heart rate, Clinical Pulmonary Infection Score(CPIS) were measured after 72 h of pull out endotracheal intubation in two groups. Sputum viscosity was evaluated by Airway Secretions Score before pull out endotracheal intubation and after 24, 48, 72 h of pull out endotracheal intubation in two groups. Results There were no significant differences between two groups in gender, age, clinical diagnosis, mechanical ventilation time, acute physiology and chronic health evaluation systemⅡrating etc (P>0.05). The breathing rate, heart rate and CPIS score respectively (20.94 ± 0.89), (80.79±4.67) times/min and (7.13 ± 2.54) points after 72 h of pull out endotracheal intubation in group B, and (24.12 ± 0.97), (86.32 ± 5.12) times/min and (8.79±3.56) points in group A, and there were significant differences(t=5.113, 7.298, 5.597, all P<0.01). PaO2, SpO2 were (93.24±1.96) mmHg(1 mmHg=0.133 kPa), 0.973 2±0.014 8 in group B, and (87.35±2.32) mmHg, 0.937 8±0.013 2 in group A, and there were significant differences(t=9.279, 4.548, all P<0.01). There was no significant difference in sputum viscosity before pull out endotracheal intubation between two groups (P>0.05). After 24, 48 and 72 h of pull out endotracheal intubation, group B of patients with sputum viscosity was suitable in group A (Z=-2.684,-2.870,-2.771, all P < 0.01). Conclusions Mechanical ventilation in patients with ventilator buoy type oxygen device for the pull out after endotracheal intubation success does not favor the sputum drainage, improve patients with dyspnea and hypoxemia is not obvious. By positive airway plus temperature humidity to sequential therapy is helpful to correct hypoxemia, improve the patients' respiratory function, reduce the breathing difficulties, reduce sputum viscosity, promote the airway drainage unblocked, shortening the time of lung infection.
