1 临床资料近年来两院共收治月经性哮喘15例,占同年收治的女性支气管哮喘的9.4％(15/141)。年龄20～40岁,平均30.3岁。病程5～15年,发病时间均于月经期前5～7天或7～10天及月经期,有哮喘家族史者6例,占40％(6/15)。发作期并发自发性气胸、纵隔气肿、呼吸衰竭各1例。为了解月经周期与肺通气功能关系,分别于月经期前一周、月经期及月经后一周内测定第1秒时间肺活量(FEV_1)、一秒时间肺活量百分比(FEV_1/FVC)、最大呼气流速峰值(PEF)、75％、50％、25％、肺活量时
1 Clinical data In recent years, the hospital treated a total of 15 cases of menstrual asthma, bronchial asthma accounted for 9.4% of the same year (15/141). Age 20 to 40 years old, an average of 30.3 years old.

Attack episodes of spontaneous pneumothorax, mediastinal emphysema, respiratory failure in 1 case. In order to understand the relationship between menstrual cycle and pulmonary function, FEV 1, FEV 1 / FVC and peak expiratory flow were measured in the first week, menstrual period and one week after menstruation respectively. (PEF), 75%, 50%, 25%, spirometry
