Vapocoolant Spray's Role in Reducing Pain During Capillary Glucose Testing
Sponsor: Abant Izzet Baysal University
Summary
Capillary blood glucose measurement is a routine procedure in emergency departments, but it may cause pain and discomfort because it requires fingertip puncture. Vapocoolant spray is a rapid, noninvasive, and inexpensive method of topical analgesia that may reduce pain during minor procedures. However, its effectiveness during capillary blood glucose testing has not been sufficiently studied. This study aims to evaluate whether vapocoolant spray reduces pain during capillary blood glucose measurement compared with placebo in adult emergency department patients requiring at least two clinically indicated glucose measurements. In this randomized, placebo-controlled crossover trial, participants receive both vapocoolant spray and placebo in a randomized sequence before two separate capillary glucose measurements. Pain is assessed immediately after each procedure using a 100 mm Visual Analog Scale. The findings may help inform practical strategies to improve patient comfort during routine glucose testing in emergency care settings.

Vapocoolant Spray
Before the capillary blood glucose measurement, vapocoolant spray will be applied to the measurement site from a distance of 30 cm for 10 seconds. Following this, the area will be cleansed with an antimicrobial swab for 10 seconds using a circular motion, starting from the center and moving outward. Subsequently, the fingertip will be punctured with a lancet to obtain a blood sample. The first drop of blood will be wiped away with cotton, and the glucose measurement will be performed using the subsequent drop utilizing the Standard GlucoNavii GDH device. The patient will then be asked to assess their pain during the procedure using the Visual Analog Scale (VAS) for pain evaluation.
Placebo
Before the capillary blood glucose measurement, placebo will be applied to the measurement site from a distance of 30 cm for 10 seconds. Following this, the area will be cleansed with an antimicrobial swab for 10 seconds using a circular motion, starting from the center and moving outward. Subsequently, the fingertip will be punctured with a lancet to obtain a blood sample.
