Background 

Pediatric patients undergoing cardiac catheterization procedures are required to lie flat for 4 hours for femoral venous access and 6 hours for femoral arterial access. Authors of research in adults suggest the flat time for the same access can be safely reduced to 1.5 to 2 hours post procedure. No literature was found that flat times could be safely reduced for pediatric patients.

Objective 

The purpose of this study was to determine whether decreased flat time for the post–cardiac catheterization pediatric patient would impact the incidence of site bleeding, additional sedation, and the need for a critical care admission.

Methods 

A randomized controlled trial was designed and participants were randomly assigned to experimental or control group. The experimental group reduced flat times to 2 hours for venous and 4 hours for arterial. The control group was standard care of 4 hours for venous and 6 hours for arterial.

Results 

A total of 119 participants were enrolled, 60 in the experimental group and 59 in the control group. Results suggest no difference in the incidence of site bleeding (P = .999), additional sedation (P = .653), or need for a critical care admission.

Conclusions 

For pediatric patients undergoing arterial or venous cardiac catheterizations, flat times can safely be reduced without increasing site bleeding, additional sedation, or critical care admissions.

一项随机对照试验，比较了心导管术后儿科患者的平坦时间与标准护理

背景 

接受心脏导管插入术的儿科患者需要平躺 4 小时进行股静脉通路，6 小时用于股动脉通路。成人研究的作者建议，相同通路的平坦时间可以安全地减少到手术后 1.5 到 2 小时。没有文献发现可以安全地减少儿科患者的平坦时间。

客观的 

本研究的目的是确定缩短心导管后儿科患者的平坦时间是否会影响部位出血的发生率、额外的镇静和重症监护入院的需要。

方法 

设计了一项随机对照试验，参与者被随机分配到实验组或对照组。实验组将静脉的平坦时间减少到 2 小时，动脉的平坦时间减少到 4 小时。对照组是静脉 4 小时和动脉 6 小时的标准护理。

结果 

共招募了119名参与者，其中实验组60人，对照组59人。结果表明，部位出血 ( P = .999)、额外镇静 ( P = .653) 或需要重症监护的发生率没有差异。

结论 

对于接受动脉或静脉心脏导管插入术的儿科患者，可以安全地减少平坦时间，而不会增加部位出血、额外镇静或重症监护入院。
