The Research Of Heated Humidifier Combined Closed Endotracheal Suctioning In The Patients With Atriifcial Airway

Objective:The purpose of this report is to explore the effects of the patients withartificial airway by using heated humidifier combined closed endotrachealsuctioning, and to provide the system methods which can regulate airwaymanagement.Methods:We selected102ill patients with artificial airway from the Neurosurgeryintensive care unit of First Hospital of Jilin University, and randomly dividedinto two groups with49cases in experimental group and53cases in controlgroup. Heated humidifier combined closed endotracheal suctioning were used inthe experimental group, and heat-moisture exchanger combined openendotracheal suctioning were used in the control group. The effect of humidific-ation, the incidence of airway spasm，the incidence of pneumonia, the reservedtime of artificial airway and the time of stay in NSICU between the two groupswere compared. All data were processed by SPSS17.0software and Excel formfor statistical analysis. Differences in measurement data were compared witht-test, the enumeration data were compared by the Chi-Square test. Results:1. There was no statistical difference (P>0.05) between two groups ofsputum viscosity on the third day. The sputum of the observation group wasthinner than the control group on the fifth (P<0.05) and seventh day (P<0.05).2. The blood oxygen saturation on the third, fifth and seventh day of thetwo groups had no statistical significance (P>0.05).3. The patients in the experimental group were not formed sputum,3cases(6.1%) patients with pulmonary infection,7cases in the control group (13.2%)of patients with sputum scab, and there were12cases (22.6%) patients withpulmonary infection. Compared with the two groups, the experimental group ofsputum scab incidence (P<0.05) and the incidence of pulmonary infection(P<0.05) were lower than the control group.4. A total of14patients in control group and5patients in experimentalgroup became airway colonized with Gram-negative bacilli; difference wasstatistically significant. Compli-cations between two groups found nostatistically signification.5. The reserved time of artificial airway in the experimental group was(7.51±2.38) d, which was (10.47±3.37) d of the control group; and the time ofstay in NSICU was (12.49±3.19) d of the experimental group,while the numberof the control group was (13.94±2.48) d. Compared two groups, theexperimental group were less than the control group. Conclusion:1. Compared with heat-moisture exchanger combined open endotrachealsuctioning, the heated humidifier combined closed endotracheal suctioningcould help to improve the effects of airway humidification，and cannot maintaina stable level in SPO2.2. Compared with heat-moisture exchanger combined open endotrachealsuctioning, the heated humidifier combined closed endotracheal suctioningcould reduce sputum viscosity, which can benefit the patients in the long run.3. Compared with heat-moisture exchanger combined open endotrachealsuctioning, the heated humidifier combined closed endotracheal suctioningcould reduce the incidence of airway spasm and pneumonia, which hadsignificant positive effect on clinical recovery.4. The heated humidifier combined closed endotracheal suctioning couldreduce the rate of bacterial airway colonization.5.Compared with heat-moisture exchanger combined open endotrachealsuctioning, the heated humidifier combined closed endotracheal suctioningcould shorten the reserved time of artificial airway and the time of stay inNSICU in order to lower its cost and enhance overall medical quality in hospital.
