Evidence is needed on the best solution for flushing central venous catheters.
To understand current flushing practices for short-term central venous catheters among critical care nurses before implementation of a randomized, controlled trial comparing physiological saline with heparin solution for flushing to maintain catheter patency.
A 6-item survey including demographic data was mailed to 2000 practicing critical care nurses in the United States. An additional 316 surveys were completed at the annual conference of the American Association of Critical-Care Nurses.
Most (71.5%) of the 632 respondents who completed the survey were staff nurses. Most respondents (64.6%; 95% CI, 60.86%-68.34%) reported using physiological saline exclusively to flush central venous catheters and maintain patency. For heparin-containing solutions, the concentration and volume used varied. The most commonly reported volumes for flushing were 10 mL for saline (63%; 95% CI, 59.18%-66.82%) and 3 mL for heparin (50.2%; 95% CI, 43.5%-56.9%).
Flushing practices for central venous catheters vary widely. A randomized controlled trial is needed to determine the optimal flushing solution to maintain short-term patency.
需要有证据来证明冲洗中心静脉导管的最佳解决方案。
在开展一项比较生理盐水与肝素溶液冲洗以维持导管通畅的随机对照试验之前，了解重症监护护士对短期中心静脉导管的当前冲洗做法。
向美国2000名执业重症监护护士邮寄了一份包含人口统计学数据的6项调查问卷。另外在美国重症护理护士协会年会上又完成了316份调查问卷。
完成调查的632名受访者中，大多数（71.5%）是注册护士。大多数受访者（64.6%；95%置信区间，60.86%-68.34%）报告仅使用生理盐水冲洗中心静脉导管并维持通畅。对于含肝素溶液，使用的浓度和体积各不相同。最常报告的冲洗体积，生理盐水为10 mL（63%；95%置信区间，59.18%-66.82%），肝素为3 mL（50.2%；95%置信区间，43.5%-56.9%）。
中心静脉导管的冲洗做法差异很大。需要进行一项随机对照试验来确定维持短期通畅的最佳冲洗溶液。
