Pressures secondary to circumferential digital dressings in clay models

Abstract

Aim: With little manipulation, compression bandages placed circumferentially around the digit can be rolled up the digit, creating a tourniquet effect. The aim of this study was to elucidate the pressures induced by self-adherent bandages applied circumferentially around the fingers.

Methods: After fabricating various clay finger models using the live finger as a model, the pressure of each self-adherent bandage was measured at the level of the proximal phalanx. Two different self-adherent bandages were applied with variables of different levels of tightness, number of wraps, and whether each was rolled up or not. Pressure was measured using a digital measuring device at a standardized location.

Results: The measured pressure of 3 wraps along the adult finger model was higher than 1 wrap or 2 wraps, and untightened bandages had lower pressures than those of tightened bandages. The pressures of the unrolled bandages were lower than those of rolled up bandages, and pressures along the live finger of the rolled up group were higher than those in the adult finger model. Additionally, measured pressures from the child finger model were higher than those from the adult model.

Conclusion: Precautions should be taken to prevent rolling up dressing materials, especially in children.
