简要总结
Peripheral intravenous cannulation (PIVC) is one of the most common interventions in medical practice. Venous dilatation is helpful for successful PIV placement. Several techniques include hot pack application, tourniquet, massaging, and tapping over the vein to increase vein caliber described in the literature. However, none of them has been rigorously studied. Therefore, there is still no 'best practice' on how to effect vein dilation in a standard way.
This study aims to investigate the effect of standardized tapping on venous dilatation with a massage device compared to manual non-standardized tapping and define a standard tapping technique using a device.
In this study, the investigators also aim to investigate the effect of tourniquet application with and without vein tapping effect on peripheral vein caliber as determined by ultrasound measurement.
详细描述
PIVC is one of the most common medical interventions in daily practice. Even though it seems like it should be an easy procedure, PIVC can be challenging.
Venous dilatation optimizes conditions for successful vein cannulation. Several techniques are described to affect venodilation, but none of them are standardized because they are done manually, and there will be individual variations among clinicians.
Tapping over the vein has been reported as an effective method. It has been hypothesized that tapping affects vein vaso-nervorum activation and local histamine release. Tapping or massage over the cannulation site is readily applied in busy medical practice, with a third of nurses using tapping or massage to promote venodilation. Tapping and massage are effective methods of vasodilatation to make the vein more prominent for venipuncture, with tapping more effective than massage (Ichimura et al.) There are limited data concerning the effect of tapping in PIVC and its standardization. In the current literature, there is no standard technique on how tapping should be performed.
Specific Aims:
- H0: Standardized tapping with a massage device is not an effective technique to dilate the peripheral veins for PIVC compared to manual tapping.
- H1: Standardized tapping with a device is a more effective technique to dilate peripheral veins for PIVC compared to manual tapping.

结局指标
主要结局
Change in standardized tapping with a device for PIVC
时间窗: 2 hours
The primary outcome is to measure the vein diameters after manual and device tapping and detect the change from baseline in vein diameters.
