目的探讨变应性鼻炎伴哮喘患者经微波治疗后,肺通气功能及呼吸阻力受到的影响和变化。方法选取变应性鼻炎伴哮喘患者43例,分别在治疗前后对所有患者进行肺功能检测。微波治疗,功率选择30 W,启动时间4 s,针对下鼻甲黏膜下、中鼻甲前段以及鼻丘进行微波多点凝固。结果总有效率100%,显效30例(69.8%)、有效13例(30.2%)。未发生不良反应或并发症。一秒用力呼气量(FEV1)、一秒呼气/用力肺活量(FEV1%)、用力呼气量75%流速(FEF75)的改善差异有统计学意义(P<0.05),用力呼气量25%流速(FEF25)、用力呼气量50%流速(FEF50)的改善差异无统计学意义(P>0.05)。结论微波治疗变应性鼻炎伴哮喘患者,肺通气功能有效改善,呼吸阻力降低。
Objective To investigate the effects and changes of pulmonary ventilation and respiratory resistance in patients with allergic rhinitis and asthma after microwave treatment. Methods Forty-three patients with allergic rhinitis and asthma were selected, and lung function tests were performed on all patients before and after treatment. Microwave treatment, power selection 30 W, start-up time 4 s, for the inferior turbinate submucosa, middle turbinate anterior and nasal microwave multi-point coagulation. Results The total effective rate was 100%, markedly effective in 30 cases (69.8%) and effective in 13 cases (30.2%). No adverse reactions or complications occurred. The FEV1, FEV1% and FEF75 improved significantly (P <0.05), forced expiratory volume 25 There was no significant difference in improvement of FEF25, FEF50 between two groups (P> 0.05). Conclusion Microwave treatment of allergic rhinitis patients with asthma, pulmonary ventilation improved effectively, respiratory resistance decreased.
