Adjustable compression wraps: stretch, interface pressures and static stiffness indices.

BACKGROUND: Adjustable compression wraps (ACWs) may represent the future of compression for the treatment of the most severe stages of chronic venous diseases and lymphedema. We tested in five healthy subjects: Coolflex® from Sigvaris®; Juzo wrap 6000®, Readywrap® from Lohmann Rauscher®; Juxtafit® and Juxtalite® from Medi®, Compreflex® from Sigvaris®. The objective of this pilot study was to study the stretch, interface pressures, and Static Stiffness Index (SSI) of the six ACWs applied to the leg. METHODS: The stretch was evaluated by stretching the ACWs to their maximum length. Interface pressure measurements were performed using a PicoPress® transducer and a probe placed at point B1. Interface pressures were measured in the supine resting position and in the standing position. We calculated the SSI. We started the measurements at 20 mmHg in the supine position and increased the pressures by 5 mmHg to 5 mmHg. RESULTS: Coolflex® (inelastic ACW) cannot exceed a maximum pressure of 30 mmHg at rest with a maximum SSI of approximately 30 mmHg. Juzo wrap 6000® (a 50% stretch) and Readywrap® (a 60% stretch) have a profile of stiffness very near one to the other. The optimal stiffness for Juzo is from 16 mmHg to of 30 mmHg for a resting pressure between 25 mmHg and 40 mmHg. For Readywrap, the optimal stiffness is from 17 mmHg to 30 mmHg with a maximum SSI of 35mmHg. The optimal application zone of this wrap at rest is 30 to 45 mmHg. Juxtafit®, Juxtalite® and Compreflex® (respectively 70%, 80%, 124% stretch) can be applied with pressures above 60 mmHg but with maximum SSI of 20 mmHg for Circaid® and>30 mmHg for Compreflex®. CONCLUSIONS: This pilot study allows us to propose a classification of wraps according to their stretch: inelastic ACW and short or long stretch ACW (50-60% and 70%, 80%, and 124% stretch). Their stretch and stiffness could help to better determine what could be expected of ACWs in clinical practice.

Limitations to self-management of adjustable compression wraps in the elderly: results of a prospective cohort study.

BACKGROUND: Adjustable compression wraps are used for treating lymphedema and chronic venous insufficiency. These diseases often affect elderly patients with associated pathologies or other limiting factors. These can prevent the self-application of the device by patients on themselves. A better understanding of these factors or the associated pathology in the elderly is important before prescribing or not prescribing a wrap. METHODS: The objective of this prospective cohort study was to determine the main factors that prevent the self-application of the device (Circaid Juxtalite, Medi Italia S.r.l., Bologna, Italy) to the lower limb in the elderly. A private nurse selected the first 30 retired subjects over 65 years of age seen at home for routine nursing care. After a demonstration, she asked them to put on the wrap to reach a pressure of 40 mmHg in the calf (point B1). She recorded the pressures as the subjects applied the wrap twice in a row. The next day, the subject repeated the application of the wrap twice. We considered that an average pressure of more than 30 mmHg is recommended to treat venous edema or ulceration. RESULTS: Thirty percent of the subjects put on the wrap by themselves with an average pressure of at least 30 mmHg. Age is not a limiting factor. Obesity, gripping difficulties, cognitive impairment and low social status seem to be factors limiting the daily self-management of an adjustable compression wrap in the elderly. CONCLUSIONS: The self-management of adjustable compression wraps in the elderly person encounters obstacles that need to be known. The investigation has revealed that obesity, gripping difficulties, cognitive impairment and low social status are limiting factors. Age was not shown to be a limiting obstacle.

Treatment protocol on stasis edema in poorly mobile nursing home patients.

BACKGROUND: Prolonged immobility in the sitting position in the elderly is known to produce venous stasis with leg edema and possible skin changes. METHODS: The authors have tested a treatment protocol in 30 patients to quantify the reduction of volume caused by an adjustable compression Velcro® wrap (Circaid Juxtalite®, medi GmbH, Bayreuth, Germany) after 15 days and to compare its effect on the leg volume for the next 15 days with 15- to 20-mmHg compression stockings (CS). RESULTS: The authors noted a volume decrease between T0 and T15 by 10.8% (52 legs) under Circaid Juxtalite®. At T30, they observed a non-significant difference between Circaid Juxtalite® (-1%) and the CS (1.3%). CONCLUSIONS: A Velcro® adjustable compression wrap (Circaid Juxtalite®) is efficient in reducing stasis edema in the elderly. Stabilization of the leg volume with the use of 15-20 mmHg CS suggests that a high pressure to maintain results is not required to maintain results.

Evaluation of three different devices to reduce stasis edema in poorly mobile nursing home patients.

BACKGROUND: Prolonged immobility in the sitting position in the elderly is known to produce venous stasis with leg edema and possible skin changes. Compression stockings are often applied for this clinical problem. There is few experienced nursing staff available to supervise the difficult task of stocking application. METHODS: The authors have researched other effective and simple devices that may be suitable alternatives. This article reports the results of three different devices to reduce leg edema, as measured by reduction in leg volume: an electro-stimulation device, an adjustable compression Velcro® wrap and a short stretch bandage, each tested over a two-hour period. RESULTS: In this randomized pilot study including 38 patients, the authors observed no difference in leg volume following electro-stimulation (Veinoplus®). They noted a significant reduction in leg volume following use of the other two devices, more with the adjustable Velcro® wrap compression (Circaid Juxtafit®) than with the short stretch bandage (Rosidal K®). Measurement of the interface pressures created by these two devices and also assessing the stiffness created by applying each device for two hours confirm that pressure is more important than stiffness in the reduction of edema in these particular patients. CONCLUSIONS: This pilot study is to be added to the results of previous published studies showing the efficacy in reducing leg edema of Velcro® adjustable compression wrap and its ease of use.
