黄牛实验性瘤胃切开术血液流变学主要指标变化规律研究

Study of Hemorheological Changes in Yellow Cattle’s Experimental Rumenotomy

为了探讨黄牛瘤胃手术血液流变学主要指标的变化规律和指导术后治疗用药。对 10头健康成年黄牛瘤胃手术前后 2周的血液流变学 ,即全血比粘度 (ηb)、血浆比粘度 (ηP)、红细胞压积 (HCT)、全血还原比粘度 (ηr)、血红蛋白含量 (HB)、红细胞沉降速度 (ESR)、红细胞聚集指数 (AI)和纤维蛋白质含量 (FG)等 8项指标进行了系统检测。结果表明 :10头黄牛在瘤胃手术后一周内其 ηb、ηP、ηr、ESR、HCT、AI和FG值比术前极明显高 (P <0 0 1或P <0 0 5 ) ,且HB值也有明显升高 (P <0 0 5 )。黄牛因外科手术中紧张不安 ,机体的应激以及术中和术后血液的丢失 。

Eight main parameters including whole blood viscosity(η b),plasmatic viscosity(η P), hematocrit(Hct), whole blood reduced viscosity(η r), hemoglobin(HB), erythrocyte sedimentation rate (ESR), erythrocyte agminate indication (AI) and fibrinogen(FG) were determinated in 2 weeks before and after rumenotomy of 10 healthy Cattle The results showed that postoperative η b,η P,η r, ESR, HCT, AI and FG are higher than that preoperative parameters ( P <0 01 or P <0 05) HB is also obviously high ( P <0 05)
