Despite a trend toward a reduction in bedrest time after left heart catheterization (LHC) in many Canadian centres, an evidence-based standard of practice has not been established. Canadian bedrest times range from two to four hours post-LHC. Two recent prospective non-randomized studies (n = 1,000) indicate safety of ambulation at 60 and 90 minutes post-LHC.
The purpose of this study was to determine safety of ambulating patients at 90 minutes post-LHC sheath removal compared to the current practice of ambulation at three to four hours post-sheath removal.
The study was a prospective non-concurrent design with a retrospective control. METHOD/SAMPLE: Retrospective data from the APPROACH database and chart reviews were analyzed for a period of six months for the control group on the traditional three- to four-hour ambulation protocol (n = 402). Prospective data were gathered for six months for the experimental group (n = 193).
There was no difference in complication rates for the two groups.
The results suggest that early ambulation for selected patients at 90 minutes is safe and has the potential to increase both patient comfort and quality of care.
尽管加拿大许多中心在左心导管插入术（LHC）后卧床休息时间有缩短的趋势，但尚未确立基于证据的实践标准。加拿大的卧床休息时间在LHC术后为两到四小时。最近两项前瞻性非随机研究（n = 1000）表明，LHC术后60分钟和90分钟下床活动是安全的。
本研究的目的是确定与目前鞘管拔除后三到四小时下床活动的做法相比，LHC鞘管拔除后90分钟让患者下床活动的安全性。
该研究是一项带有回顾性对照的前瞻性非同期设计。
方法/样本：对APPROACH数据库的回顾性数据和病历审查进行了为期六个月的分析，对照组采用传统的三到四小时下床活动方案（n = 402）。对实验组进行了为期六个月的前瞻性数据收集（n = 193）。
两组的并发症发生率没有差异。
结果表明，选定患者在90分钟时早期下床活动是安全的，并且有可能提高患者舒适度和护理质量。
