Objective The dorsal artery and femoral artery blood gas analysis of collection of specimens and clinical results were compared and analyzed. Methods Between January 2012 to December 2013,70 patients with the need for multiple blood gas analysis were included into this study. The dorsal artery blood collection and femoral artery blood collection patient blood with syringe diameter 2 cm were performed in all these patients. The results were compared. Results The success rate of blood,differences in dorsal arterial blood sampling and femoral arterial blood sampling was not statistically significant( P > 0. 05). The values in pressing time,hematoma,ecchymosed probability and degree of dorsal artery of foot pain in dorsal arterial blood were better than femoral arterial blood sampling,there was significant difference( P > 0. 05). PaO2 dor-sal artery and femoral artery Law Act,PaCO2 ,SaO2 ,pH difference were not statistically significant( P > 0. 05). Conclusion ABG specimen collection dorsal approach can effectively reduce pressing time,reduce pain in patients with blood during conducive to safe blood,the higher the degree of acceptance of the patient.%目的：对足背动脉和股动脉的血气分析标本的采集方式以及结果进行临床对比和分析。方法选取2012年1月至2013年12月需要进行多次血气分析的患者70例，分别使用足背动脉采血法、股动脉采血法对患者进行采血，注射器直径2 cm，将两种方法的血的成功率、疼痛视觉模拟（VAS）评分、血肿和瘀斑、按压时间、患者依从性和动脉血气结果进行比较。结果采血成功率方面，足背动脉采血法和股动脉采血法的差异无统计学意义（ P >0.05）。在按压时间、血肿程度、瘀斑概率和疼痛值方面，足背动脉法采血优于股动脉采血法，差异具有统计学意义（ P >0.05）。两种方法的血样氧分压（PaO2）、二氧化碳分压（PaCO2）、血氧饱和度（SaO2）、pH 比较差异无统计学意义（ P >0.05）。结论足背动脉血气分析标本采集方式能够有效减少按压时间，减轻患者在采血过程中的疼痛，有利于采血的安全，患者的接受程度较高。
