目的 :探讨重症监护室(ICU)感染患者的降钙素源(PCT)水平及其变化规律。方法 :将我院2012年7月2013年8月ICU收治的98例ICU感染患者,根据患者感染的细菌类型及是否复合感染分组测定感染后第1d、第3d、第5d、第7d、第14d、第21d的PCT水平,并进行相关比较和分析。结果 :三组PCT值在同一时间点比较差异均均具有统计学意义,三组间两两比较差异在同一时点比较具有统计学意义。三组间的PCT值比较差异具有统计学意义。结论 :对于重症监护室(ICU)感染患者的感染类型可以通过细菌培养等方式确诊,也可以通过测定患者的PCT水平及其变化趋势进行辅助判断。
Objective: To investigate the level of calcitonin (PCT) and its variation in patients with intensive care unit (ICU) infection. Methods: A total of 98 ICU patients admitted to ICU from July 2012 to August 2013 in our hospital were enrolled in this study. According to the types of patients infected with ICU or whether the patients were infected with ICU or not, 1d, 3d, 5d, 7d, 14d , The 21st day of the PCT level, and make the relevant comparison and analysis. Results: The PCT values of the three groups were statistically significant at the same time point, and the differences between the two groups at the same time point were statistically significant. PCT values between the three groups were statistically significant differences. CONCLUSIONS: Infection types in patients with intensive care unit (ICU) infections can be confirmed by bacterial culture or by determining the level of PCT in patients and their trends.
