    Abstract：Objective To observe the curative effect of hypertonic saline inhalation in treatment of lower respiratory tract infection.Methods100 patients with lower respiratory tract infections were randomly divided into the treatment group and control group with 50 cases in each group. The treatment group received 3% hypertonic saline inhalation of 20ml twice a day,while the control group received physiological saline inhalation of 20ml twice a day.Observed the curative effect and adverse reactions of the two groups,then took statistical analysis.ResultsFor the treatment group, 36 cases(78.26%) were markedly improved,7 cases(15.22%) were effective,3 case(6.52%) ineffective,and 4 cases received adverse reaction.For the control group,25 cases(51.02%)were markedly improved,13 cases(26.53%)were effective,11 cases(22.45%)ineffective,and 1 case received adverse reaction.Both groups differ in total effective rate but not in incidence adverse reactions.ConclusionThe curative effect of hypertonic saline inhalation in treatment of lower respiratory tract infection is satisfactory and this therapy were proved secure. ......
