To Evaluate the Influence and Efficacy in Treatment of Airway Resistance in Laryngeal Cough Using Method of Nourishing Yin and Dispelling Wind

Objective:To explore the curative effect using method of nourishing Yin and dispelling wind in treatment of laryngeal cough(type of yin-deficiency and wind-dryness)and the influence of airway resistance.Methods:Fifty objects who suffered from laryngeal cough were selected.Thirty in treatment group being given Xuan mai cough instant granule and twenty in control group being given Ji zhi syrup.Xuan mai cough instant granule was thawed in boiling water,taken orally and drinking 200mL twice every day.Ji zhi syrup was also taken orally and drinking 20mL three times every day.Both duration is 7 days.We observed the change of clinical symptoms and airway resistance'index.Results:Clinical heal rate、notable effective rate、effective rate and inefficiency rate in treatment group respectively are 3.3%、53.3%、40%、3.4%,and meantime 0%、5%、35%、60% in control group.Data analysis indicated that treatment group apparently higher than control group.Leading symptoms,Clinical heal rate,notable effective rate、effective rate are all better than control group.Further more,indexes of Zrs、R5、R20、R35 are remarkable reduced in treatment group and the efficacy is better than control group.Conclusion:The method of nourishing Yin and dispelling wind can remarkable relieve a cough.It apparently reduce airway resistance.Test of IOS can be the objective index to diagnose laryngeal cough and evaluate efficacy.
