Variations in peak nasal inspiratory flow among healthy students after using saline solutions

ABSTRACT INTRODUCTION: Nasal hygiene with saline solutions has been shown to relieve congestion, reduce the thickening of the mucus and keep nasal cavity clean and moist. OBJECTIVE: Evaluating whether saline solutions improve nasal inspiratory flow among healthy children. METHODS: Students between 8 and 11 years of age underwent 6 procedures with saline solutions at different concentrations. The peak nasal inspiratory flow was measured before and 30 min after each procedure. Statistical analysis was performed by means of t test, analysis of variance, and Tukey's test, considering p

引言：采用生理盐水（saline solutions）进行鼻腔清洁，已被证实可缓解鼻塞、降低黏液黏稠度，并维持鼻腔清洁湿润。
研究目的：评估生理盐水是否可改善健康儿童的鼻腔吸气峰流量（peak nasal inspiratory flow）。
研究方法：招募8至11岁的学生，对其开展6次不同浓度生理盐水冲洗鼻腔的操作。于每次操作前及操作后30分钟，分别测量其鼻腔吸气峰流量。采用t检验（t test）、方差分析（analysis of variance）以及Tukey检验（Tukey's test）进行统计学分析，以p值[原文未完整给出]。
