We assessed the agreement between non-invasive (oscillatory) blood pressure (NIBP) measurements and invasive intra-arterial blood pressure (IBP) in the pediatric cardiac critical care unit.
Children with intra-arterial lines as per standard management protocol were enrolled. NIBP was measured every 4 hourly and the corresponding IBP reading was recorded.
A total of 839 brachial NIBP, 834 IBP femoral (IF), and 137 IBP radial (IR) readings were noted on 45 participants. The mean difference (95% CI) for agreement between NIBP and IF was -2.3 (-27.1, 22.5) mmHg for systolic, 0.9 (-21.3, 23.1) mmHg for diastolic and 0.3 (-23.3, 23.9) mmHg for mean BP. Similar results were found between NIBP and IR and between IF and IR. The interrater agreement [Kappa (95% CI)] was fair between NIBP and IF [0.54 (0.48, 0.61)], and IF and IR [0.62 (0.48, 0.76)] but lower between NIBP and IR [0.37(0.20, 0.55)] when values were classified as hypotensive, normotensive, and hypertensive.
NIBP cannot replace but can supplement IBP in the pediatric cardiac critical care setting.
我们评估了在儿科心脏重症监护病房中，无创（振荡）血压（NIBP）测量与有创动脉内血压（IBP）之间的一致性。
按照标准管理方案纳入有动脉内置管的患儿。每 4 小时测量一次 NIBP，并记录相应的 IBP 读数。
在 45 名参与者中，共记录了 839 次肱动脉 NIBP、834 次股动脉 IBP（IF）和 137 次桡动脉 IBP（IR）读数。NIBP 与 IF 之间的平均差值（95%CI）在收缩压为-2.3（-27.1，22.5）mmHg，舒张压为 0.9（-21.3，23.1）mmHg，平均血压为 0.3（-23.3，23.9）mmHg。NIBP 与 IR 之间以及 IF 与 IR 之间也存在类似的结果。NIBP 与 IF 之间的组内一致性[Kappa（95%CI）]为中等（0.54（0.48，0.61）），IF 与 IR 之间的组内一致性为良好（0.62（0.48，0.76）），但当将血压值分为低血压、正常血压和高血压时，NIBP 与 IR 之间的组内一致性较低，为 0.37（0.20，0.55）。
NIBP 不能替代但可以补充儿科心脏重症监护环境中的 IBP。
