摘要目的：探讨氨溴索雾化吸入辅助治疗肺部感染的效果观察及对CRP水平的影响。方法选取肺部感染患者68例，采用随机数字表法将其分为观察组（n ＝34）与对照组（n ＝34）。观察组采用氨溴索雾化吸入进行治疗，对照组采用糜蛋白酶雾化吸入进行治疗。比较两组临床效果及症状、体征消失时间等，并对两组治疗前后血清 CRP 水平变化进行比较。结果观察组治疗后临床总有效率为91．2％，对照组总有效率为70．6％，两组比较差异有统计学意义（χ2＝4．316，P ＜0．05）；与对照组比较，观察组患者症状消失时间（3．1±0．5）d、肺部体征消失时间（4．1±1．7）d、体温恢复正常时间（4．1±1．6）d 及住院时间（8．4±2．8）d 均明显缩短，差异均有统计学意义（t 分别为2．879、2．918、3．025、3．972，均 P ＜0．05）；与治疗前比较，观察组血清 CRP水平（22．45±9．27）mg／L 与对照组患者血清 CRP 水平（33．45±14．67）mg／L 均明显降低，差异均有统计学意义（t 值分别为6．314、5．126，均 P ＜0．05）；其中观察组血清 CRP 水平降低程度明显优于对照组，差异有统计学意义（t ＝6．263，P ＜0．05）。结论氨溴索雾化吸入辅助治疗肺部感染的临床效果显著，能显著缩短患者症状、肺部体征消失时间及住院时间等，并降低血清 CRP 水平，值得在临床上推广应用。

abstractsObjective To study the clinical efficacy and effects on CRP levels of ambroxol in treatment of pulmonary infections.Methods 68 patients with pulmonary infection were selected and divided into the observation group(n =34)and control group by using the random number table method(n =34).The observation group was treated with ammonia bromine atomization inhalation treatment,while the control group was treated with alpha chymo-trypsin atomization inhalation therapy.The clinical effect and duration of symptoms and signs disappeared of the two groups were compared,and serum CRP level changes in the two groups before and after treatment were also compared. Results After treatment,the clinical total effective rate was 91.2% of the observation group.And the total effective rate was 70.6% in control group,the comparison between the two groups had statistically significant difference (χ2 =4.316,P <0.05).Compared with the control group,the observation group patients symptoms disappear time(3.1 ± 0.5)d,pulmonary symptoms disappear time(4.1 ±1.7)d,body temperature returned to normal time(4.1 ±1.6)d and hospital stay(8.4 ±2.8)d were significantly shortened,the differences were statistically significant (t =2.879, 2.918,3.025,3.972,all P <0.05 ).The serum CRP levels in patients of the observation group was (22.45 ± 9.27)mg/L,which of the control group was (33.45 ±14.67 )mg/L,both were significantly lower than before treatment,the difference was statistically significant (t =6.314,5.126,all P <0.05).The lower degree of serum CRP level in the observation group was obviously better than tha in the control group,the difference was statistically significant (t =6.263,P <0.05).Conclusion The ambroxol can achieve significant clinical effect on treatment of pulmonary infections,which can significantly shorten the patientˊs symptoms and lung signs disappear time and length of hospital stay,etc.It can reduce the serum CRP level,and is worth popularization and application in clinic.
