摘要:

目的 探讨亚低温治疗对猪心脏骤停(CA)体外心肺复苏(ECPR)后凝血功能及炎性因子的影响。方法 采用随机数字表法将12只巴马香猪分为对照组、常温组和亚低温组,每组4只。常温组和亚低温组经右心室诱颤建立CA模型,随后采用体外膜肺氧合(ECMO)进行ECPR,常温组目标体温37 ℃,亚低温组目标体温34 ℃,对照组仅进行造模常规置管。24 h后处死动物,取静脉血检测凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、凝血酶时间(TT)、纤维蛋白原(FIB)及D-二聚体(D-D)水平。采用酶联免疫吸附试验(ELISA)测定肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)的表达水平。结果 常温组和亚低温组PT、APTT、TT、FIB、D-D、TNF-α及IL-6表达水平均高于对照组,亚低温组各指标低于常温组(P<0.05)。结论 亚低温治疗可显著改善猪CA经ECPR后凝血功能,并降低炎性因子表达水平,从而减轻ECPR相关并发症及炎症反应的发生。

Abstract:

Objective To investigate effects of mild hypothermia treatment on coagulation function and inflammatory factors in a swine model of extracorporeal cardiopulmonary resuscitation (ECPR) after cardiac arrest (CA). Methods Using random number table method, twelve Bama pigs were divided into the control group, the normal temperature group and the mild hypothermia group with four pigs in each group. CA model was established by right ventricular fibrillation in the normal temperature group and the mild hypothermia group, and then ECPR was performed by extracorporeal membrane oxygenation (ECMO). The target temperature of the normal temperature group was 37 ℃, and the mild hypothermia group was 34 ℃. Control group was only given conventional tube placement. Pigs were killed 24 hours later, and venous blood was taken to detect levels of prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (FIB) and D-dimer antigen (D-D). Expression levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected by enzyme linked immunosorbent assay (ELISA). Results Compared with the control group, PT, APTT, TT, FIB, D-D and expression levels of TNF-α and IL-6 were significantly increased in the normal temperature group and the mild hypothermia group. Compared with the normal temperature group, the above indicators were decreased significantly in the mild hypothermia group (P<0.05). Conclusion Mild hypothermia treatment can significantly improve coagulation function and reduce the release of inflammatory factors in a swine model of ECPR after CA, so as to alleviate the occurrence of ECPR-related complications and inflammatory reactions.
