Abstract

目的 明确95 μl动脉血在危重患儿的血气分析检测中与195 μl动脉血检测结果的一致性。 方法 北京儿童医院重症医学科住院患儿,采集动脉血标本0.6 ml,使用雷度ABL-835型血气分析仪进行195 μl和95 μl不同进样量检测,分析两种进样量血气分析结果的一致性,进行ICC Bland-Altman一致性检验。 结果 2016年10月至2018年5月获得150例患儿的入院首次动脉血样本,不同进样量检测结果显示pH值、PaCO2、PaO2、K+、Ca2+、GLU、BE、HCO3-一致性>0.950;Na+、Cl-一致性>0.900;Lac一致性>0.850,即血气分析11项数值检验一致性好。 结论 采用95 μl动脉血进行血气检测可提供与195 μl动脉血检测一致性较好的结果,适用于体重小的早产儿、低出生体重儿,可减少因采血量不足产生的废血或反复穿刺。
小儿重症监护病房不同动脉血容量血气结果的一致性
Clear Purpose 95 μ The relationship between arterial blood and blood gas analysis in critically ill children μ Consistency of arterial blood test results. Method: A total of 0.6 ml of arterial blood samples were collected from hospitalized children in the Intensive Care Department of Beijing Children's Hospital, and 195 samples were analyzed using the Rayleigh ABL-835 blood gas analyzer μ L and 95 μ Detect the consistency of blood gas analysis results with different injection volumes and conduct ICC Bland Altman consistency test. Results From October 2016 to May 2018, 150 first-time arterial blood samples were obtained from hospitalized children. The results of different injection volumes showed consistency of pH, PaCO2, PaO2, K+, Ca2+, GLU, BE, HCO3->0.950; Na+, Cl - consistency>0.900; Lac consistency>0.850, indicating good consistency in the 11 numerical tests of blood gas analysis. Conclusion adopts 95 μ Blood gas testing of arterial blood can provide a comparison with 195 μ The consistent results of arterial blood testing are suitable for small weight premature infants and low birth weight infants, and can reduce waste blood or repeated punctures caused by insufficient blood collection.
