目的探讨羧甲淀粉钠溶液对儿童反复呼吸道感染(RRI)的预防作用。方法 150例反复呼吸道感染患儿,按照随机原则分为对照组和观察组,每组75例。给予对照组患儿抗感染、抗病毒等一般性常规治疗,观察组患儿在常规治疗的基础上服用羧甲淀粉钠溶液,观察比较两组患儿用药后的治疗效果以及临床症状表现和体征变化。结果对照组和观察组患儿的治疗总有效率分别为77.33%、96.00%,两组比较差异具有统计学意义(P<0.05)。观察组患儿的咳嗽缓解时间、退热时间、扁桃体红肿消退时间及肺部啰音消失时间均显著优于对照组,差异具有统计学意义(t=9.749、5.314、5.594、4.452,P<0.05)。结论反复呼吸道感染患儿服用羧甲淀粉钠溶液,能有效改善临床症状,且减少发病次数,提高自身的免疫力,由此可知,羧甲淀粉钠溶液能有效预防儿童出现反复呼吸道感染的症状。
Objective To investigate the preventive effect of sodium carboxymethyl starch solution on children with recurrent respiratory tract infection (RRI). Methods 150 cases of children with recurrent respiratory tract infection were randomly divided into control group and observation group, with 75 cases in each group. The control group of children with anti-infection, anti-virus and other general treatment routine observation, the observation group patients taking sodium carboxymethyl starch solution on the basis of conventional treatment, observation and treatment of two groups of children after treatment, as well as clinical symptoms and signs Variety. Results The total effective rates of the control group and the observation group were 77.33% and 96.00%, respectively. The difference between the two groups was statistically significant (P <0.05). The cough relief time, antipyretic time, tonsil infiltration time and pulmonary rales disappeared in the observation group were significantly better than those in the control group (t = 9.749,5.314,5.594,4.452, P <0.05 ). Conclusions Children taking recurrent respiratory tract infection with sodium carboxymethyl starch solution can effectively improve the clinical symptoms, reduce the frequency of onset and improve their immunity. Thus, sodium carboxymethyl starch solution can effectively prevent the symptoms of recurrent respiratory tract infection in children.
