BACKGROUND Cerebrospinal fluid (CSF) analysis is an important component of the evaluation of horses with neurologic disease. Lumbosacral (LS) centesis is routine, but CSF is also collected from the space between the first and second cervical vertebrae (C1-C2). OBJECTIVES To compare collection times, CSF cytology results, and equine protozoal myelitis (EPM) titers of CSF collected from the C1-C2 and LS sites. ANIMALS Fifteen university-owned adult horses with no evidence of neurologic disease, and 9 horses with signs of neurologic disease: 3 university-owned and 6 client-owned. METHODS Prospective study. Cerebrospinal fluid collection from the LS space and C1-C2 space of each horse was performed in randomized order. Continuous data were analyzed using mixed-effects linear models and count data using mixed-effects negative binomial regression. Statistical significance was set at P < .05. RESULTS Cerebrospinal fluid collected from the C1-C2 site had a significantly lower mean protein concentration (49 [95% CI: 43-55.8] mg/dL C1-C2 versus 52.1 [95% CI: 45.7-59.3] mg/dL LS; P = .03) and red blood cell count (6 [95% CI: 2-16] cells/μL versus 33 [95% CI: 13-81] cells/μL; P = .02). Collection time, total nucleated cell count, EPM titers, and serum:CSF EPM titer ratios were not significantly different between collection sites. CONCLUSIONS AND CLINICAL IMPORTANCE Cerebrospinal fluid from the C1-C2 space provides an acceptable alternative to LS CSF collection with decreased likelihood of clinically important blood contamination of samples.

比较从站立的,成年的成年马进行脑脊液分析的两种收集方法。

背景技术脑脊液(CSF)分析是评估患有神经系统疾病的马匹的重要组成部分。腰ac部(LS)穿刺是常规的,但是CSF也从第一和第二颈椎(C1-C2)之间的空间收集。目的比较收集自C1-C2和LS位点的CSF的收集时间,CSF细胞学结果和马原生动物脊髓炎(EPM)滴度。动物15头大学拥有的成年马没有神经系统疾病的证据,9匹有神经系统疾病的迹象的马:3头由大学拥有,6头由客户拥有。方法前瞻性研究。从每匹马的LS空间和C1-C2空间收集脑脊液以随机顺序进行。使用混合效应线性模型分析连续数据,并使用混合效应负二项式回归对数据进行计数。统计学显着性设定为P <.05。结果从C1-C2位点收集的脑脊液平均蛋白浓度显着降低(C1-C2 49 [95%CI:43-55.8] mg / dL LS与52.1 [95%CI:45.7-59.3] mg / dL LS; P = .03)和红细胞计数(6 [95%CI:2-16]细胞/μL,而33 [95%CI:13-81]细胞/μL; P = .02)。收集时间,收集的总有核细胞数,EPM滴度和血清:CSF EPM滴度比在收集点之间没有显着差异。结论和临床意义C1-C2空间的脑脊液为LS CSF收集提供了一种可接受的替代方法,同时降低了对临床重要血液样本的污染的可能性。结果从C1-C2位点收集的脑脊液平均蛋白浓度显着降低(C1-C2 49 [95%CI:43-55.8] mg / dL LS与52.1 [95%CI:45.7-59.3] mg / dL LS; P = .03)和红细胞计数(6 [95%CI:2-16]细胞/μL,而33 [95%CI:13-81]细胞/μL; P = .02)。收集时间,收集的总有核细胞数,EPM滴度和血清:CSF EPM滴度比在收集点之间没有显着差异。结论和临床意义C1-C2空间的脑脊液为LS CSF收集提供了一种可接受的替代方法,同时降低了对临床重要血液样本的污染的可能性。结果从C1-C2位点收集的脑脊液平均蛋白浓度显着降低(C1-C2 49 [95%CI:43-55.8] mg / dL LS与52.1 [95%CI:45.7-59.3] mg / dL LS; P = .03)和红细胞计数(6 [95%CI:2-16]细胞/μL,而33 [95%CI:13-81]细胞/μL; P = .02)。收集时间,收集的总有核细胞数,EPM滴度和血清:CSF EPM滴度比在收集点之间没有显着差异。结论和临床意义C1-C2空间的脑脊液为LS CSF收集提供了一种可接受的替代方法,同时降低了对临床重要血液样本的污染的可能性。总有核细胞数,EPM效价和血清:CSF EPM效价比在收集位点之间无显着差异。结论和临床意义C1-C2空间的脑脊液为LS CSF收集提供了一种可接受的替代方法,同时降低了对临床重要血液样本的污染的可能性。总有核细胞数,EPM效价和血清:CSF EPM效价比在收集位点之间无显着差异。结论和临床意义C1-C2空间的脑脊液为LS CSF收集提供了一种可接受的替代方法,同时降低了对临床重要血液样本的污染的可能性。
