简要总结
The primary objective is to compare the difference in the pain score in radial arterial puncture using the insulin needle versus the standard 23G hypodermic needle.
详细描述
In a randomised, crossover design, healthy volunteers were recruited to receive bilateral radial arterial punctures. They were assigned to receive either the insulin or the standard needle as the first puncture using block randomisation. The primary outcome was the pain score measured on a 100mm visual analogue scale (VAS) and the secondary outcomes were procedural complications and rate of haemolysis.

结局指标
主要结局
Visual analogue scale (VAS) score in millimetres
时间窗: Immediately after each puncture ( average within 5 minutes)
Immediately following the radial arterial punctures the outcome assessor asked the volunteer to assess the discomfort that was caused by the puncture. The volunteer was asked to place a slash on a 100 mm VAS sheet. The VAS showed "no pain" at 0 mm and "worst pain" at 100 mm.
次要结局
- blood haemolysis(Immediately after collection)
