目的 观察中度哮喘未控制与良好控制患儿肺通气功能、呼气一氧化氮及身高的变化,为临床指导规范用药提供依据。方法 收集2017年1月-2018年6月期间符合中度哮喘儿童,分为2组,未控制组(50例,间断使用ICS联合孟鲁司特治疗),良好控制组(50例,规律使用ICS联合孟鲁司特治疗),同时选取50例非哮喘健康儿童作为对照组。在治疗6个月和12个月后,未控制组与良好控制组进行FEV1、PEF和FeNO检测,同时对三组患儿进行身高检测。结果 治疗6个月和12个月后,未控制组FEV1、PEF缓解程度明显低于良好控制组(P<0.05),而且未控制组FeNO下降不明显,且高于良好控制组(P<0.05)。治疗12个月后,良好控制组患儿身高与对照组儿童身高差异无统计学意义(P>0.05),然而未控制组患儿身高明显落后于对照组儿童身高(P<0.05)。结论 不规律用药导致哮喘控制不良,引起气道高反应性及通气功能障碍,同时也是影响儿童身高的重要因素。
Abstract
Objective To observe the changes of pulmonary ventilation function, fractional exhaled nitric oxide (FeNO) and height in children with uncontrolled group and well-controllled group of moderate asthma. Methods Children with moderate asthma from January 2017 to June 2018 were collected, and were divided into uncontrolled asthma group (50 cases with intermittent use of ICS combined with Menglusite) and well-controlled group (50 cases with regular use of ICS combined with Menglusite). Meantime, 50 cases with non-asthmatic children were selected into the control group. After 6 months and 12 months of treatment, the uncontrolled group and the well-controlled group performed FEV1, PEF, and FeNO tests, and the height of three groups of children was measured. Results After 6 months and 12 months of treatment, FEV1 and PEF were significantly lower in uncontrolled group than those in well-controlled group (P<0.05). And FeNO in uncontrolled group did not decrease significantly and was higher than that in well-controlled group (P<0.05).After 12 months of treatment, the height of children in well-controlled group was not significantly different compared with that of the control group (P>0.05), while the height of children in the uncontrolled group was significantly lower than that of the control group (P<0.05). Conclusion Irregular use of drugs leads to poor asthma control, resulting in hyperractivity of airway and ventilation dysfunction, and is also an important factor affecting the height of children.
