Performance of an adjustable compression wrap in occupational leg swelling.

BACKGROUND: Edema in some subjects worsens over time and wraps help to reduce the leg volume. MATERIAL AND METHODS: An adjustable compression wrap was tried on volunteers for 5 h and volumes measured in each limb before and after wrapping using a 3D surface scanner (HandySCAN 3D®) to estimate the volume of the leg. The contralateral leg was used as control. RESULTS: We observed a significant decrease in volume in the wrap legs and an increase in the control legs (p < .001), both in the lower part of leg (p = .001) and in the upper part (p = .001). CONCLUSIONS: Using the Readywrap® for 5 hours significantly reduces the leg volume. This study enables Readywrap to be studied in a population that is easy to observe in the context of a research program. The Handyscan3D® was shown accurate and reproducible to assess leg volume in future studies.

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.

Is There a Difference in the Clinical Efficacy of Diosmin and Micronized Purified Flavonoid Fraction for the Treatment of Chronic Venous Disorders? Review of Available Evidence.

Flavonoids are oral venoactive drugs frequently prescribed to relieve the symptoms of chronic venous disorders (CVD). Among venoactive drugs, diosmin is a naturally occurring flavonoid glycoside that can be isolated from various plant sources; it can also be obtained after conversion of hesperidin extracted from citrus rinds. Micronized purified flavonoid fraction (MPFF) is a preparation that contains mainly diosmin and a small fraction of hesperidin. We performed a state-of-the-art literature review to collect and analyze well-conducted randomized clinical studies comparing diosmin - also called non-micronized or hemisynthetic diosmin - 600 mg a day and MPFF, 1000 mg a day. Three clinical studies met the criteria and were included for this literature review. These clinical studies showed a significant decrease of CVD symptom intensity (up to approximately 50%) and global patient satisfaction after one-to-six-month treatment with diosmin or MPFF, without statistical differences between these two forms of diosmin. Both treatments were well tolerated with few mild adverse drug reactions reported. Overall, based on this literature review, there is no clinical benefit to increase the dose of diosmin beyond 600 mg per day, to use the micronized form, or to add hesperidin, since clinical efficacy on venous symptomatology is achieved with 600 mg per day of pure non-micronized diosmin. This challenges the status of diosmin - 600 mg a day - in guidelines for the management of CVD, which is currently categorized 2C (weak recommendations for use and poor quality of evidence), while the most widely used and assessed preparation MPFF is rated 1B (strong recommendation for use and moderate quality of evidence).

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.

Prospective randomized controlled study of patient compliance in using a compression stocking: Importance of recommendations of the practitioner as a factor for better compliance.

Background Patient compliance is the cornerstone of compression therapy success. However, there has been up to now no tool to assess it other than self-reporting by the patient, which is not reliable. Material and methods Forty active females classified C2S were enrolled to wear compression stockings (CS) providing a pressure of 15-20 mmHg at the ankle. A thermal probe was inserted in the stocking (Thermotrack®), recording the skin temperature every 20 min for four weeks. The patients were randomized in two groups of 20: - Group 1: Receiving minimal recommendations by their physician at the office. - Group 2: Receiving in-depth recommendations by the physician reinforced with SMS message which were repeated once a week for four weeks. The basic CEAP classification and the quality of life (QoL) were recorded before and after four weeks. Results The two groups are similar for age, symptoms and type of CS. The analysis of the thermal curves showed a significant increase (+33%) in the average wearing time daily in the group 2: 8 h vs. 5.6 h (group1) p < 0.01. The average number of days worn per week is also increased: 3.4 (group 1) vs. 4.8 (group 2), thus improving patient compliance from 48.5% to 70% as a direct result of the physician recommendations ( p < 0.001). Conclusion This is the first study assessing the real compliance in CVD patients of using compression. It shows that better and repeated recommendations by the practitioner result in an increase in time the compression is used by 33%. The study also suggests that the number of days the compression stocking is worn is a good criterion of patient compliance.

Difficulty associated with donning medical compression stockings: results from a survey comparing two different compression stockings.

AIM: Although medical compression stockings (MCSs) represent the cornerstone of conservative treatment for patients with chronic venous disease, high rates of noncompliance exist. This study compared comfort levels and the difficulty associated with putting on/removing two different MCSs; a conventional degressive MCS (ankle pressure: 24-28 mmHg; calf pressure: 14-18 mmHg) and a progressive MCS (ankle pressure: 8-12 mmHg; calf pressure: 21-25 mmHg). PATIENTS & METHODS: Women wearing class III MCSs in the past 3 months were recruited from across France to complete an at-home, investigator-led questionnaire, designed to evaluate their experience with putting on/taking off MCSs. Patients were randomized to two groups (group 1: controls, degressive stocking right leg, then left leg; group 2: degressive stocking right leg, then progressive stocking left leg). RESULTS & CONCLUSION: Patients (n = 102) in group 1 (controls) reported no differences after wearing the degressive MCS on the right leg then the left leg. By contrast, group 2 patients (n = 118) reported statistically significant improvements with the progressive MCS compared with the degressive MCS in all questionnaire parameters, including 'comfort' and 'ease of putting on/taking off' dimensions. Progressive MCSs were associated with significantly better outcomes (ease of putting on/taking off and comfort) than the conventional MCSs.

Dogmas and controversies in compression therapy: report of an International Compression Club (ICC) meeting, Brussels, May 2011.

The International Compression Club (ICC) is a partnership between academics, clinicians and industry focused upon understanding the role of compression in the management of different clinical conditions. The ICC meet regularly and from these meetings have produced a series of eight consensus publications upon topics ranging from evidence-based compression to compression trials for arm lymphoedema. All of the current consensus documents can be accessed on the ICC website (http://www.icc-compressionclub.com/index.php). In May 2011, the ICC met in Brussels during the European Wound Management Association (EWMA) annual conference. With almost 50 members in attendance, the day-long ICC meeting challenged a series of dogmas and myths that exist when considering compression therapies. In preparation for a discussion on beliefs surrounding compression, a forum was established on the ICC website where presenters were able to display a summary of their thoughts upon each dogma to be discussed during the meeting. Members of the ICC could then provide comments on each topic thereby widening the discussion to the entire membership of the ICC rather than simply those who were attending the EWMA conference. This article presents an extended report of the issues that were discussed, with each dogma covered in a separate section. The ICC discussed 12 'dogmas' with areas 1 through 7 dedicated to materials and application techniques used to apply compression with the remaining topics (8 through 12) related to the indications for using compression.

[Compression treatment of venous and venous/arterial leg ulcers]. / La compression de l'ulcère de jambe veineux et mixte.

The French National Authority for Health has recalled recommendations for the use of compression in the treatment of venous or venous/arterial leg ulcers. Different types of bandages and compression stockings must be used. The pressure to be achieved is between 30 and 40 mm Hg at the ankle (and below 30 mm Hg in case of mixed ulcers). In daily practice, beyond these recommendations, the choice of type of compression must also take into account the size of the ulcer, the appearance of the wound, the existence of leg dysmorphia, the volume of the oedema and also the general condition of the patient.

Classification of compression bandages: practical aspects.

BACKGROUND: Compression bandages appear to be simple medical devices. However, there is a lack of agreement over their classification and confusion over the use of important terms such as elastic, inelastic, and stiffness. OBJECTIVES: The objectives were to propose terms to describe both simple and complex compression bandage systems and to offer classification based on in vivo measurements of subbandage pressure and stiffness. METHODS: A consensus meeting of experts including members from medical professions and from companies producing compression products discussed a proposal that was sent out beforehand and agreed on by the authors after correction. RESULTS: Pressure, layers, components, and elastic properties (P-LA-C-E) are the important characteristics of compression bandages. Based on simple in vivo measurements, pressure ranges and elastic properties of different bandage systems can be described. Descriptions of composite bandages should also report the number of layers of bandage material applied to the leg and the components that have been used to create the final bandage system. CONCLUSION: Future descriptions of compression bandages should include the subbandage pressure range measured in the medial gaiter area, the number of layers, and a specification of the bandage components and of the elastic property (stiffness) of the final bandage.

Measurement of lower leg compression in vivo: recommendations for the performance of measurements of interface pressure and stiffness: consensus statement.

BACKGROUND: Interface pressure and stiffness characterizing the elastic properties of the material are the parameters determining the dosage of compression treatment and should therefore be measured in future clinical trials. OBJECTIVE: To provide some recommendations regarding the use of suitable methods for this indication. METHOD: This article was formulated based on the results of an international consensus meeting between a group of medical experts and representatives from the industry held in January 2005 in Vienna, Austria. RESULTS: Proposals are made concerning methods for measuring the interface pressure and for assessing the stiffness of a compression device in an individual patient. CONCLUSIONS: In vivo measurement of interface pressure is encouraged when clinical and experimental outcomes of compression treatment are to be evaluated.
