【摘要】 目的探讨腺样体、扁桃体肥大患儿肺功能的改变及手术对其影响。方法选择因腺样体,扁桃体肥大住院手术患儿130例,采用MS-IOS肺功能仪检测其肺功能,并对术前肺功能异常的50例患儿术后随诊并再次行肺功能检测。采用呼吸阻抗(Zr)、共振频率(Rf),黏性阻力R5、R20,弹性阻力X5、X35,中心气道阻力(Rc)、外周气道阻力(Rp)等参数,分析不同程度腺样体、扁桃体肥大患儿以上参数的改变及手术前后的差异。结果腺样体、扁桃体肥大患儿多数存在气道阻塞,Z5、R5、R20、X5、Rc、Rp等值偏高;但不同程度腺样体、扁桃体肥大患儿肺功能水平未见统计学差异(P>0.05);与术前比较,患儿手术后气道阻塞程度明显减轻,表现为Z5、R5、R20等参数显著改善(P<0.05)。结论腺样体、扁桃体肥大患儿多数存在气道阻塞,手术切除可明显减轻下气道阻塞程度。因此,对腺样体、扁桃体肿大患儿应早期干预,以消除对通气功能的影响。更多还原

【Abstract】 Objective Explore the pulmonary function in children with adenoid and tonsil hypertrophy and it changes by operation .Method 130 children with adenoid and tonsil hypertrophy were enrolled in the study.MS-IOS pulmonary function testing was performed preoperatively for each patient,and repeated postoperatively for 50 patients with abnormalities in preoperative one.Respiratory impedance( Zr),resonance frequency(Rf),viscous resistance of R5,R20,X5,X35 elastic resistance,central airway resistance(Rc ),peripheral airway resistance(Rp) and other parameters were evaluated.The influence of different hypertrophic degree of adenoid and tonsil,and of operative intervention were also inverstigated.Results Adenoid and tonsil hypertrophy resulted in a significant high value in Z5,R5,R20,X5,Rc and Rp,However,hypertropic degrees showed unclear affection(P > 0.05 ).Surgical intervention presented an obviously improvement in Z5,R5 and R20(P < 0.05 ).Conclusion Airway obstruction existed in children with adenoid and tonsil hypertrophy was reduced by adenoidectomy and tonsillectomy.Early surgical intervention is necessary in order to eliminate the impairment on ventilation function in these children.更多还原
