正常麻醉犬动脉血和脑脊液酸碱电解质关系的初步分析

A Preliminary Study on The ACIA-BASE and Electrolyte Relating Between Arterial Blood and Cerebrospinal in Normal Anesthetized Dogs

３０只健康麻醉犬动脉血和脑脊液（ＣＳＦ）酸碱变量及主要电解质检测结果分析发现：ＣＳＦｐＨ、〔Ｋ＾＋〕〈ｐＨａ和〔Ｋ＾＋〕ａ，相互之间相关显著，其回归方程分别为ＣＳＦｐＨ＝０．４７７×ｐＨａ＋３．７８，ＣＳＦ〔Ｋ＾＋〕＝０．４１８×〔Ｋ＾＋〕ａ＋１．１２。ＣＳＦＰＣＯ２、〔Ｃ１＾－〕、〔乳酸〕〔Ｌａｃｔ〕〉ＰａＣＯ２、〔Ｃｌ＾－〕ａ和〔Ｌａｃｔ〕ａ，相互之间相关显著。

Arterial blood and cerebrospinal fluid(CSF):samples from 30 normal anesthetized dogs were analyzed.Results are as follows: CSF pH and[K]were lower than arterial blood(P<0.0l)the liner regression equation were respectively CSF pH=0.477pHa+3.78: CSF[K+]=0.418[K+]a+1.12CSF Pco2.[Cl-]. And [Lactate] were tigher than arterial blood(P<0.01).the liner regression were respectively CSF pco2=0.564 PaCO=3.5325; CSF[Cl-]=0.5[Cl-]a+76.7;CSF[Lactate]=0.05[Lactate]a+1.0 Comparison of [HCO3-] and [Na+] between arterial blood and CSF were on significance. There was a significanetly positive corelation between CSFPCO2 and CSF [HCO3-]=1.898CSFPCO2+10.6
