Arterial Puncture Using Insulin Syringe is Less Painful Than Standard Syringe

November 21, 2013 updated by: Emergency, National University Hospital, Singapore

Arterial Puncture Using Insulin Syringe is Less Painful Than Standard Syringe, a Randomized Crossover Study

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.

Study Overview

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visual analogue scale (VAS) score in millimetres
Time Frame: 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.
Immediately after each puncture ( average within 5 minutes)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
blood haemolysis
Time Frame: Immediately after collection
The serum collected during the punctures was analysed for the amount of free haemoglobin. We define presence of haemolysis as free haemoglobin concentration of more than 100 mg/dL.
Immediately after collection
