Exploring key elements in bandage structure for effective compression therapy

Improper compression bandage application can result in ineffective edema management, leading to pain and decreased patient adherence to treatment. The successful application depends on the operator’s experience, bandage overlap, and applied tension. In addition, the bandages’ structural properties are essential for sustained compression. This study investigates how compression bandage structure influences slippage, leg conformity, and therapeutic pressure application. It focuses on the effect of intermeshing, stiffness, and design for pressure consistency, comparing a dual compression system (DCS) with a traditional two-layer bandage (TLB). The DCS includes visual indicators to help practitioners achieve target pressure through proper extension and overlap. Methods involved a bench test, photographic microscopy, and a preliminary nonclinical study. The bench test evaluated bandage slippage and subbandage pressure using a leg model, photographic microscopy examined bandage intermeshing, and the nonclinical study assessed the effectiveness of the visual indicators in assisting nurses in achieving a target pressure of 40 ± 10 mmHg. Results showed that the TLB did not conform to the leg model after a 4 cm circumference reduction and significantly decreased stiffness after a 2 cm reduction ( P < 0.05). In contrast, the DCS maintained its stiffness and conformed to the simulated leg despite the reduction in circumference. The nonclinical study revealed that nurses with no prior experience performed more effectively with the DCS after online training, while an experienced TLB nurse demonstrated proficiency with the DCS following both online and in-person training. This study emphasizes the importance of understanding bandage stretch properties to achieve the appropriate pressure levels, thus optimizing compression effectiveness.
