Abstract

This study was aimed at revealing the effects of relieving psychological burdens by the use of a newly designed intravenous catheter with a stopping valve for protecting from bleeding during the procedures of inserting the catheter. The use of an intravenous catheter with a stopping valve catheter A) and that of a conventional IV catheter were compared by a questionnaire survey of 536 health care workers and the time motion analysis using video observations and interviews of six infection control practitioners. As a result, 73.0% of the users of the catheter A mentioned that its use was effective for patient safety and 82.3% of them answered that it was useful for improving the quality of care by health care workers. The procedure for keeping peripheral intravenous routes was easier by using the catheter A than that by using a conventional catheter. From the motion analysis, the use of the catheter A reduced the aver age operating time of the non-dominant hand for “pressing” it by 7 sec compared with the use of a conventional catheter. Interestingly, the operation of the non-dominant hand to “release” and “hold” the catheter increased by 2 sec. It was considered that the catheter A with a stopping valve eliminated the need for blood leakage prevention by pressing the vessel, thus securing the flexibility of the non-dominant hand and a margin of the work and reducing anxiety by exposure to contaminated blood. On the other hand, examples of blood leakage after releasing the hemostasis valve due to carelessly forgetting the existence of a stopping valve were also reported. This risk of blood exposure posed by the introduction of new equipment added to the conventional product was also confirmed.
