目的探讨支气管哮喘控制测试(asthma control test,ACT)与最大呼气峰流速(PEF)在成人哮喘缓解期阶梯治疗中的应用。方法分析2013年1月至2014年9月收治的80例成人哮喘患者的临床资料,对患者进行ACT评分,并用PEF-2型峰速仪测量患者的PEF。结果 80例患者中75例哮喘得到有效控制,哮喘控制率为93.8%。ACT评分0~20分5例,PEF-pred%为(73.2±6.9)%;20~25分75例,EF-pred%为(104.6±9.1)%。两者PEFpred%差异有统计学意义(P<0.05)。PEF-pred%<80%5例,ACT评分(16.9±1.1);≥80%75例,ACT评分(24.1±1.2)。两者差异有统计学意义(P<0.05)。PEF-pred%与ACT评分呈线性相关关系(r=0.147,P<0.05)。结论 ACT和PEF的相关性良好,均能够为临床评价哮喘提供有效依据,进而对阶梯治疗进行积极指导。二者联合应用的临床价值更高。
Objective To investigate the application of asthma control test (ACT) and maximum expiratory flow rate (PEF) in the treatment of asthma in adult stage. Methods Clinical data of 80 adult patients with asthma admitted from January 2013 to September 2014 were analyzed. ACT scores of patients and PEF-2 peak velocity instrument were used to measure the PEF. Results Among the 80 patients, 75 cases of asthma were effectively controlled and the control rate of asthma was 93.8%. ACT score was 0 to 20 in 5 cases. PEF-pred% was (73.2 ± 6.9)%. There were 75 cases in 20-25 points, and EF-pred% was (104.6 ± 9.1)%. PEFpred% difference between the two was statistically significant (P <0.05). PEF-pred% <80% in 5 cases, ACT score (16.9 ± 1.1); ≥80% in 75 cases, ACT score (24.1 ± 1.2). The difference was statistically significant (P <0.05). There was a linear correlation between PEF-pred% and ACT score (r = 0.147, P <0.05). Conclusion The correlation between ACT and PEF is good, which can provide an effective basis for the clinical evaluation of asthma and further guide the treatment of step. The combination of the two clinical value is higher.
