Abstract

OBJECTIVE

Arterial blood gas analysis is an iatric component factor in the clinical evaluation of patients, but arterial puncture has many complications. Our study aimed to determine a correlation between arterial and venous blood gas values.

METHODS

A prospective comparison of 200 samples from 100 patients undergoing lumbar disc surgery was conducted. Arterial and venous samples were obtained simultaneously from each patient. The samples were analyzed and compared using SPSS version 16 software, with Pearson's correlation and 95% confidence intervals (CIs) of the difference.

RESULTS

Arterial and venous values for pH, bicarbonate (HCO(3)), base excess (BE), buffer base (BB) and partial pressure of carbon dioxide (PCO(2)) showed close and direct correlation. The comparison showed the following: pH, r = 0.938, p <0.001 (95% CI, 0.019 to 0.032); HCO(3), r = 0.884, p <0.001 (95% CI, -2.65 to -1.99); BE, r = 0.861, p <0.001 (95% CI, -1.89 to -1.17); BB, r = 0.849, p < 0.001 (95% CI, -2.35 to -1.60); and PCO(2), r = 0.899, p < 0.001 (95% CI, -5.97 to -4.66). Pearson's correlation coefficients for partial pressure of oxygen and oxygen saturation were 0.092 and 0.345, respectively. The mean difference between arterial and venous values for pH was 0.025 pH units, for HCO(3) was 2.327 mmol/L, for PCO(2) was 5.32 mmHg, for BE was 1.533 mmol/L, and for BB was 1.983 mmol/L.

CONCLUSION

Venous blood gas values are an acceptable alternative to arterial blood gas values in patients undergoing lumbar disc surgery.

摘要

目的

动脉血气分析是临床评估患者的一个医学组成因素，但动脉穿刺有许多并发症。我们的研究旨在确定动脉和静脉血气值之间的相关性。

方法

对100例行腰椎间盘手术患者的200份样本进行前瞻性比较。同时从每位患者获取动脉和静脉样本。使用SPSS 16版软件对样本进行分析和比较，计算Pearson相关性及差异的95%置信区间（CI）。

结果

pH值、碳酸氢根（HCO₃）、碱剩余（BE）、缓冲碱（BB）和二氧化碳分压（PCO₂）的动脉和静脉值显示出密切的直接相关性。比较结果如下：pH值，r = 0.938，p <0.001（95%CI，0.019至0.032）；HCO₃，r = 0.884，p <0.001（95%CI，-2.65至-1.99）；BE，r = 0.861，p <0.001（95%CI，-1.89至-1.17）；BB，r = 0.849，p <0.001（95%CI，-2.35至-1.60）；PCO₂，r = 0.899，p <0.001（95%CI，-5.97至-4.66）。氧分压和氧饱和度的Pearson相关系数分别为0.092和0.345。pH值的动脉和静脉值平均差异为0.025个pH单位，HCO₃为2.327 mmol/L，PCO₂为5.32 mmHg，BE为1.533 mmol/L，BB为1.983 mmol/L。
