目的：目的是确定动脉化的指尖血气样本是否与静止和运动时的动脉样本具有可比性。设计：重复测量，受试者作为自己的对照。单位：加拿大魁北克省蒙特利尔蒙特利尔总医院麻醉科（2004年1月至4月）。参与者：15名健康男性（年龄= 25±4岁，体重= 76.4±11.4 kg，身高= 180.7±8.0 cm，峰值摄氧量= ov0312， o2峰值= 46.0±9.0 mL·kg−1·min−1）。主要观察指标：动脉血气、代谢物、电解质。结果：在一个电子制动测力仪上，同时从桡动脉和加热的指尖采集血液，在休息和两个水平的运动（剧烈181 W或70% &OV0312； o2峰值；最大261 W或100% &OV0312； o2峰值）期间。休息和运动两种水平联合的动脉血氧分压比动脉化指尖样本平均高13.6±9.0 mm Hg，其中休息时差异最大（18.8±6.5 mm Hg, 95% CI = 15.5, 22.1），运动最高水平时差异最小（8.3±9.2 mm Hg, 95% CI = 3.6, 13.0, P < 0.05）。血氧饱和度的模式是相同的，在采样点之间显示出统计学差异，在最高运动强度下差异减小。相比之下，两个采样点在静止或两种运动水平下的动脉血二氧化碳分压和动脉血二氧化碳分压（- 1.0±1.5 mm Hg; 95% CI = - 1.4, - 0.6），血浆乳酸、葡萄糖、pH、血红蛋白和电解质均无差异。结论：静息和运动时动脉化指尖血样可预测动脉二氧化碳压，预测动脉血浆乳酸、葡萄糖、pH、血红蛋白和电解质；但不是动脉血氧饱和度或动脉血氧压。
Objective:The purpose was to determine whether arterialized fingertip blood-gas samples are comparable to arterial samples at rest and at exercise. Design:Repeated measures, with subjects serving as their own controls. Setting:Department of Anesthesia, Montreal General Hospital, Montreal, Quebec, Canada, (January to April 2004). Participants:Fifteen healthy men (age = 25 ± 4 y; weight = 76.4 ± 11.4 kg; height = 180.7 ± 8.0 cm; peak oxygen uptake or &OV0312;O2peak = 46.0 ± 9.0 mL · kg−1 · min−1). Main outcome measures:Arterial blood gases, metabolites, electrolytes. Results:Blood sampled simultaneously from the radial artery and warmed fingertip at rest and during 2 levels of exercise (vigorous 181 W or 70% &OV0312;O2peak; maximal 261 W or 100% &OV0312;O2peak) on a electronically braked ergometer. Arterial partial pressure of oxygen in blood combining rest and the 2 exercise levels was on average 13.6 ± 9.0 mm Hg higher than arterialized fingertip samples, with the largest difference occurring at rest (18.8 ± 6.5 mm Hg; 95% CI = 15.5, 22.1) and the smallest difference occurring at the highest level of exercise (8.3 ± 9.2 mm Hg; 95% CI = 3.6, 13.0; P < 0.05). The pattern for oxyhemoglobin saturation was the same, showing statistical differences between the sampling sites with the differences reduced at the highest exercise intensity. In contrast, there was no difference in arterial and arterialized partial pressure of carbon dioxide in blood (−1.0 ± 1.5 mm Hg; 95% CI = −1.4, −0.6), or plasma lactate, glucose, pH, hemoglobin, and electrolytes between both sampling sites at rest or at the 2 exercise levels. Conclusion:Arterialized fingertip blood samples at rest and during exercise can predict arterial carbon dioxide pressure, and can predict arterial plasma lactale, glucose, pH, hemoglobin, and electrolytes; but not arterial oxyhemoglobin saturation or arterial oxygen pressure.
