  • Effects of Arterial Blood Gas Index Control during Invasive Mechanical Ventilation on Prognosis in COPD Patients with Hypercapnic Respiratory Failure

    ObjectiveTo investigate the effects of arterial blood gas index control during invasive mechanical ventilation on prognosis in COPD patients with type Ⅱ respiratory failure. MethodsSeventy-six COPD patients with hypercapnic respiratory failure who underwent invasive mechanical ventilation were recruited in the study. The patients were divided into group A with conventional arterial blood gas index control [pH of 7.40±0.05,PaO2 of (70±5)mm Hg,PaCO2 of (55±5)mm Hg],and group B with low index control [pH of 7.35±0.05,PaO2 of (60±5)mm Hg,PaCO2 of (60±5)mm Hg]. Two groups were compared on the required parameters of invasive mechanical ventilation,the duration of invasive mechanical ventilation,the incidence rate of sequential therapy in noninvasive mechanical ventilation,ventilator associated pneumonia and secondary intubation,etc. ResultsThe required parameters of invasive mechanical ventilation in group B including tidal volume (VT) and pressure support (PS),the duration of invasive mechanical ventilation,the incidence rate of sequential therapy in noninvasive mechanical ventilation,ventilator associated pneumonia and secondary intubation were all significantly lower than those in group A (P<0.05). ConclusionThe strategy to permit a lower PaO2 and carbon dioxide retention to a certain extent at lower FiO2,VT and PS levels in invasive mechanical ventilation can reduce the duration of invasive mechanical ventilation and the occurrence of ventilator associated complications,and improve the prognosis in COPD patients with type Ⅱ respiratory failure.

  • Comparison of Emergency Orotracheal Intubation by Two Different Methods of Holding Laryngoscope

    ObjectiveTo explore the methods to improve the success rate of intubation and reduce the intubation time consuming in emergency orotracheal intubation by improving the method of holding laryngoscope. MethodsA total of 146 patients needed orotracheal intubation were randomly divided into a traditional group who was intubated with traditional method of holding laryngoscope and an improved group who was intubated with improved method of holding laryngoscope. The success rate of intubation for the first time, success rate in difficult intubation, intubation time consuming, the incidence of complications by mechanical injury between two groups were compared. ResultsSixty-nine petients received traditional method of holding laryngoscope and 77 petients received improvement method of holding laryngoscope. The success rate for the first time intubation [71(92.2%) vs. 56(81.2%)] and success rate in difficult intubation [13(72.2%) vs. 3(23.1%)] of the improved group were higher than those of the traditional group. The differences were statistically significant (all P < 0.05). The intubation time consuming [(28.3±3.5)s vs. (35.6±4.1)s] and the incidence of complications by mechanical injury [1(1.3%) vs. 6(8.7%)] of the improved group were lower than those of the traditional group with statistical significance (all P < 0.05). ConclusionThe success rate of intubation for the first time and the difficult intubation can be improved effectively, and the intubation time consuming and the incidence of complications by mechanical injury can be reduced effectively by improving the method of holding laryngoscope.
