Abstract：
OBJECTIVE: To compare plasma l-lactate (LAC) values between samples collected from jugular and cephalic venipuncture in healthy horses and systemically ill horses.
METHODS: Prospective, experimental study.
METHODS: Large animal university teaching hospital.
METHODS: Thirty healthy adult university-owned horses and 43 client-owned horses presenting to the large animal hospital for elective surgical procedures or for emergent medical evaluation of systemic illness.
METHODS: Blood samples were collected from the jugular vein (JV) and cephalic vein (CV) and placed in EDTA blood tubes prior to any medical therapy. LAC values were obtained with a handheld lactate meter at the time of blood collection.
RESULTS: LAC was higher in CV samples than JV samples in healthy horses (P < 0.001); however, all values were within the normal reference range. Similarly, LAC was higher in CV samples than JV samples in systemically ill horses (P < 0.001), but the median JV value was within normal reference range (1.9 mmol/L [17.1 mg/dL]), while the median CV value was outside the normal reference range (2.9 mmol/L [26.1 mg/dL]).
CONCLUSIONS: The CV is an alternative venipuncture site for assessing plasma LAC if the JV is not accessible or to preserve the JV for subsequent catheterization. However, in ill horses, the CV value may be outside the reference range when the corresponding JV value would have been within the reference range.

摘要：
目的：比较从颈静脉和头静脉穿刺采集的健康马和全身疾病马的血浆L-乳酸（LAC）值。
方法：前瞻性，实验研究。
方法：大动物大学教学医院。
方法：30匹健康成人大学拥有的马匹和43匹客户拥有的马匹前往大型动物医院进行选择性外科手术或对系统性疾病进行紧急医学评估。
方法:在任何药物治疗之前,从颈静脉(JV)和头静脉(CV)收集血样并置于EDTA血液管中。在血液收集时用手持式乳酸计获得LAC值。
结果：健康马的CV样本中的LAC高于JV样本（P<0.001）；然而，所有值均在正常参考范围内.同样，在系统性病马中，CV样本中的LAC高于JV样本(P<0.001)，但JV中值在正常参考范围内（1.9mmol/L[17.1mg/dL]），而中值CV值超出正常参考范围（2.9mmol/L[26.1mg/dL]）。
结论：如果无法接近JV，则CV是评估血浆LAC的替代静脉穿刺部位，或保留JV用于随后的导管插入。然而,生病的马，例如,当对应的JV值将已经在参考范围内时,CV值可以在参考范围之外。
