Study: NCT05915234

Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: Frozen peas
Description: Each participant will receive two active devices and one sham comparator in a crossover design. The cryotherapy device used consists of an opaque bag with a plastic outer cover and an aluminum interior filled with 80 grams of frozen peas. This device is applied on the skin where the optimal palpation point of the radial artery is located, where arterial puncture for blood gas analysis is usually performed to reduce skin temperature in ranges that decrease nerve conduction velocity and increase pain threshold.

Intervention: Room temperature gel
Description: Each participant will receive two active devices and one sham comparator in a crossover design. The sham comparator device used consists of an opaque bag with an external plastic cover and an aluminum interior filled with 80 grams of ultrasound gel at room temperature. This device is applied on the skin where the optimal palpation point of the radial artery is located, where arterial puncture for blood gas analysis is usually performed.
