In patients with peripheral intravenous catheters (PIVCs), performing flushing is an essential procedure to maintain catheter patency and prevent complications. These PIVC related complications can lead to premature removal and therapeutics interruption, which implies the need of a new catheterization thus increasing patient discomfort and pain.
To identify nursing practices related to the flushing procedure, namely: moment(s) of the flushing; the syringe size used; the flush solution, volume and technique; the knowledge and accomplishment of the recommended standards on flushing by nurses.
A cross-sectional study was conducted between July and December 2017, with Brazilian and Portuguese nurses. An online questionnaire was developed based on the international recommendations on flushing procedure. Descriptive analysis was performed.
A total of 76 nurses answered the questionnaire. The majority of nurses (84.2%) performed flushing: the most common technique used was continuous syringe pressure (31.2%), with the push-pause technique being performed by 23.4% of the nurses. Despite the majority performs flushing at four distinct moments (after the PIVC insertion, before, between and after drug delivery), there are inconsistencies in flush solution, volume, and syringe size. The most used volume to perform flushing was 5 mL, filled using normal saline. Despite this, they also recognized the omission of this procedure due to time constrains, no familiarity with the procedure and unavailable material.
This study identified that flushing procedure isn't always performed by nurses in their clinical practice. Also, several inconsistencies were observed between nurses that performed flushing, reflecting the lack of empirical evidence in this area of research.
对于外周静脉导管（PIVC）患者而言，进行冲管是维持导管通畅和预防并发症的必要操作。这些与PIVC相关的并发症可能导致导管过早拔除和治疗中断，这意味着需要重新进行置管，从而增加患者的不适和疼痛。
确定与冲管操作相关的护理实践，即：冲管的时机；所用注射器的规格；冲管溶液、容量和技术；护士对推荐冲管标准的知晓情况和执行情况。
2017年7月至12月对巴西和葡萄牙的护士进行了一项横断面研究。基于国际冲管操作建议制定了一份在线问卷。进行了描述性分析。
共有76名护士回答了问卷。大多数护士（84.2%）进行冲管：最常用的技术是持续注射器推注压力（31.2%），23.4%的护士采用推-停技术。尽管大多数护士在四个不同时刻进行冲管（PIVC插入后、给药前、给药期间和给药后），但在冲管溶液、容量和注射器规格方面存在不一致。冲管最常用的容量是5 mL，使用生理盐水填充。尽管如此，他们也认识到由于时间限制、不熟悉该操作和材料不可用而未进行此操作。
本研究发现护士在临床实践中并非总是进行冲管操作。此外，在进行冲管的护士之间观察到了一些不一致之处，反映出该研究领域缺乏实证依据。
