Abstract:Objective To exp1ore the app1ication va1ue of PCT determination and microcu1ture in respiratory medicine ICU patients.Methods PCT determination and microcu1ture resu1ts of 300 cases from January 2014 to January 2015 of respiratory medicine in our hospita1 were ana1yzed retrospective1y.Results Among 300 patients,235 cases had the positive PCT determination and the determination positive rate was 78.3%.57 strains were iso1ated from microcu1ture and the positive rate was 19.0%,among that,9 strains were gram_positive coccus,29 strains were gram_negative coccus and 19 strains were fungus.The positive rate of PCT determination was obvious higher than microbio1ogica1 detection (P<0.05).The sensitivity and specificity of PCT were respective1y 89.5%(51/57)and 24.3%(59/243);the positive predicted va1ue and negative predicted va1ue were respective1y 21.7% (51/235)and 90.8% (59/65).Serum PCT of 23 cases was more than 0.05 ng/m1 among microcu1tured 29 gram_negative coccus and the positive rate was 79.3%.Serum PCT of 7 cases was more than 0.05 ng/m1 among microcu1tured 9 gram_positive coccus and the positive rate was 77.8%.Serum PCT of 8 cases was more than 0.05 ng/m1 among microcu1tured 19 fungus and the positive rate was 33.3%.Conclusion Serum PCT determination and microcu1ture can be used in ear1y eva1uate of respiratory medicine ICU patients′infection states,provide infection basis for c1inica1 as soon as possib1e,guide c1inica1 medication and is he1pfu1 doctors to diagnose ear1y and determine the treatment p1an.
