变应性鼻炎伴哮喘患者微波治疗前后肺通气功能和呼吸阻力改变的研究

Changes of pulmonary ventilation function and respiratory resistance in patients with allergic rhinitis and asthma after microwave treatment

目的 探讨微波治疗前后变应性鼻炎伴哮喘患者肺通气功能和呼吸阻力改变情况。方法 变应性鼻炎伴哮喘患者39例，分为微波治疗前组和微波治疗后组。对患者鼻腔进行微波治疗，分别在微波治疗前和治疗后3～6个月测定肺通气功能并进行对照分析。结果 患者经微波治疗后一秒呼气/用力肺活量（FEV1%）显著提高，肺活量（VC）、用力肺活量（FVC）、一秒用力呼气量（FEV1）、最大呼气峰流速（PEF）、用力呼气量25%流速（FEF25）、用力呼气量50%流速（FEF50）、用力呼气量75%流速（FEF75）值相对升高。结论 对既往有哮喘病史的变应性鼻炎患者进行鼻腔微波治疗，可使患者肺通气功能相对改善，呼吸阻力降低。

Objective To explore the changes of pulmonary ventilation function and respiratory resistance in patients with allergic rhinitis and asthma after nasal microwave treatment. Methods Thirtynine patients with allergic rhinitis were chosen to receive nasal microwave treatment. The pulmonary ventilation functions of these patients were measured and compared before and 3～6 months after microwave treatment. Results After nasal microwave treatment, the forced expiratory rate in one second （FEV1%） increased significantly. Vital capacity （VC）, forced vital capacity （FVC）, forced expiratory volume in one second （FEV1）, peak expiratory flow rate （PEF）, forced expiratory volume flow rate of 25% （FEF25）, forced expiratory volume flow rate of 50% （FEF50） and forced expiratory flow rate of 75% （FEF75） also increased. The airway obstruction decreased after microwave treatment. Conclusions The pulmonary ventilation function of patients with allergic rhinitis who had the history of asthma was improved while the respiratory resistance decreased.
