目的比较从动脉留置针经T型延长管与直型延长管采集动脉血标本的血气分析结果,减少医源性失血。方法对30例重症心胸术后留置动脉留置针的患者,分别用常规直型延长管采血与从动脉留置针连接T型延长管采血。结果两种采血方法血气分析结果及电解质比较,差异无统计学意义(均P>0.05)。结论在动脉留置针处连接T型延长管采血行动脉血气分析检测是可行的。
Objective To compare the results of blood gas analysis of arterial blood samples taken from arterial catheter with T-type extension tube and straight extension tube to reduce iatrogenic blood loss. Methods Thirty patients with indwelling arterial indwelling needle after severe cardiothoracic surgery were collected with conventional straight extension tube and T extension tube respectively. Results There was no significant difference in blood gas analysis results and electrolytes between the two blood sampling methods (all P> 0.05). Conclusion It is feasible to connect the T type extension tube blood sampling arterial blood gas analysis in the artery indwelling needle.
