脓毒性休克是指由于脓毒症引起的休克,其常见表现是患者组织灌注不足,即给予充分液体复苏后仍出现持续低血压状态,具有病情凶险,病死率高的特点〔1-2〕。目前已有大量研究证实,降钙素原(PCT)对脓毒性休克患者的病情程度判断及疗效评估存在较大价值,其诊断感染的敏感性高达86%~97%,特异性高达81%~100%〔3〕。PCT浓度和感染严重程度有关:脓毒性休克时患者PCT
Septic shock refers to the shock caused by sepsis, the common manifestation of the patient’s tissue perfusion is insufficient, that is, given sufficient liquid resuscitation continued to appear low blood pressure state, with dangerous conditions, high mortality [1-2]. At present, a large number of studies have demonstrated that procalcitonin (PCT) has great value in judging the severity of disease and evaluating the curative effect in patients with septic shock. The sensitivity of the diagnosis of infection is as high as 86% -97% and the specificity is as high as 81% 100% [3]. The PCT concentration is related to the severity of the infection: PCT in patients with septic shock
