[Abstract] Objective To investigate the change of procalcitonin in adult with respiratory tract infection in the early period after the cardiac postoperative.Methods The procalcitonin level was detected before the cardiac operative, at the end of surgery, postoperative 24 h, 48 h, 72 h in 286 patients with over 18 years of age,including 35 cases in cardiac surgery patients with respiratory tract bacterial infections occurred within 72 hours(infection group) and 251 cases of patients who were not affected (control group) during in the first five months 2016. Results The procalcitonin level was significantly higher at the end of surgery(1.18±0.07) ng/mL, postoperative 24 h(2.36±1.45) ng/mL、48 h(1.78±0.98) ng/mL、72 h(1.47±0.65) ng/mLin uninfection group and the end of surgery(1.65±0.44) ng/mL, postoperative 24 h(5.59±1.77) ng/mL、48 h(6.74±3.54) ng/mL、72 h(8.43±3.36) ng/mL in infection group than the preoperative(0.05±0.01) ng/mL(P<0.05); The procalcitonin level was significantly higher in infection group in 24, 48, 72 h after operation than uninfected group (P < 0.05). Conclusion The procalcitonin level increases in the early period after the cardiac postoperative with respiratory tract bacterial infections.

心臟病是嚴重威脅人類健康疾病之一,心臟術后的呼吸道感染是最常見的心外并發癥,如果治療不及時,可導致敗血癥,多器官功能衰竭導致患者死亡[1]。早期識別感染,準確把握病情,合理使用抗菌藥物,是我們醫務工作者所追求的理想;目前降鈣素原(PCT)的被認為是感染的敏感指標[2],然而多種因素可引起PCT升高;如何去偽存真,找到心臟術后感染的早期征象,在疾病初期及時控制感染,改善患者預后。該研究通過觀察該院2016年1—5月行心臟手術患者286例,檢測心臟圍術期PCT的動態變化,了解心臟術后感染的PCT變化特征,指導臨床治療,現報道如下。
