目的 研究脓毒症大鼠早期血清中炎性因子与心肌损伤之间的相关性。方法 72只雌性清洁级SD大鼠随机分
为假手术组(n=36)和脓毒症组(n=36),分别行盲肠探查术、盲肠结扎穿孔术,均于术后3、9、24、36、48和72h采腹主动脉血检测
肌钙蛋白I(cTnI)、肿瘤坏死因子 α(TNF α)、白细胞介素 1(IL 1)水平。结果 TNF α、IL 1于3h达峰值,后逐渐降低,均高于假
手术组(P<005);cTnI于3h达峰值,后逐渐降低,均高于假手术组(P<005);血清TNF α、IL 1均与cTnI呈显著正相关。
结论 脓毒症早期炎症因子的升高与心肌损伤具有正相关性,可作为检测和诊断早期脓毒症心肌损伤的重要指标。 |
