大耳白兔动脉血和脑脊液酸碱电解质值及其相互关系

３０只正常大耳白兔，经股动脉穿刺插管和枕骨下经皮穿刺入枕骨下池，在严格隔绝空气情况下，分别取得动脉血和脑脊液（ＣＳＦ）标本，用ＡＢＬ３型血气分析仪及ＣＮ６４４型生化分析仪检测主要酸碱变量及电解质值。经统计学处理结果表明：ＣＳＦｐＨｅｙ ｋ＾＋、Ｃａ＾２＋、Ｍｇ＾２＋浓度〈动脉血，ＣＳＦＰＣＯ２及ＨＣＯ３＾－、Ｃｌ＾－Ｎａ＾＿、Ｈ＾＋〉动脉血。另外，ＣＳＦＰＨ与ｐＨａ，ＣＳＦＰＣＯ２与ＰａＣＯ２、Ｃ

Acid-base and Electrolytes Values and Relati on Between CSF and Arterial Blood in Normal Big Ear Rabbits

Arterial blood and ceve brospinal fluid (CSF) samples from 30 normal big ear rabbits were analyzed. Results as follows:pH,K +,Ca 2+ ,Mg 2+ in CSF were lower than those in the arterial blood; PCO 2,HCO - 3,Cl -,Na +,H + CSF were higher than in those the arterial blood too. There were significant correlation between CSFpH and pHa, between CSFPCO 2 and PaCO 2, between CSFK +] and K +]a, between CSFCl -] and Cl -]a. According to our study, there are differences in acid base variables and electrolytes are between CSF and anterial blood and CSF is not Filtrates of the plasma.
