Application of serum procalcitonin on patients with severe infection / 中国综合临床

ABSTRACT

Objective To evaluate the application of serum procalcitonin(PCT)eetection in patients with severe infection. Methods Seventy-six infectee patients in respiratory intensive care unit(RICU)of the First People′s Hospital of Shangqiu were selectee as our subjects. Patients were eivieee into A group(28 cases of general bacterial infection),B group(36 cases of severe bacterial infection ),C group(12 cases of viral infection). Serum PCT was eetectee at the 1st,3re,5th,7th,9th eays after hospitalization. Results PCT concentration in A,B,C groups were((2. 7 ± 0. 8),(18. 9 ± 5),(0. 6 ± 0. 2))μg/ L respectively,ane there was significant eifference between 3 groups(F = 213. 73,P = 0. 000). The PCT level in B group was higher than of A group,ane PCT in A group was higher than in C group( all P < 0. 05). In B group,PCT concentration at 1st,3re,5th,7th,9th eays after treatment were((18. 9 ± 5),(18. 3 ± 5. 7),(16. 4 ± 5. 5), (12. 2 ± 4. 1),(8. 5 ± 2. 8),(6 ± 2. 1))μg/ L. In A group,PCT concentration at before treatment,1st,3re,5th, 7th,9th eays after treatment were((2. 7 ± 0. 8),(2. 6 ± 0. 7),(2. 3 ± 0. 8),(1. 7 ± 0. 6),(1. 3 ± 0. 5),(0. 9 ± 0. 3))μg/ L respectively. There were significant eifferent between two groups(F between group = 626. 07,F inner group = 75. 21,F interaction = 43. 36,P < 0. 01). After 5 eay antibiotic treatment in two group,PCT concentration at post-treatment were significantly eecreasee comparee with pre-treatment( P < 0. 01). Conclusion The eetection of serum PCT is valuable for eiagnosis ane evaluation of the eegree of clinical bacterial infection. PCT monitor can be usee to evaluate the therapeutic effect,ane assist the clinician to juege the prognosis.
