Objective To investigate the nursing effect of humidified heating airway on the off-line of tracheostomy postoperative patients.Methods Fifty six cases of off-line of tracheostomy post operative patients were randomly divided into the experiment group and control group.The experiment group was given continuous warming humidification to airway,and control group was cared by the method of micro pump continuous drip.Comfort,sputum viscosity and phlegm scab formation incidence were compared between the two groups.Results The difference of between the two groups was statistically significant in the comfort and sputum viscosity(all P < 0?05)?Treatment effect in the experiment group was obviously better than that in the control group.There was no significant difference in phlegm scab formation between the experiment group and the control group(P > 0?05).Conclusion The application of humidified heating airway to the off-line of tracheostomy postoperative patients can increase comfort,reduce sputum viscosity,and the method ean be used in clinical nursing?
