Measurement of forces associated with compression therapy.

Compression therapy is the principal treatment for leg ulcers associated with venous disease. The efficacy of compression therapy can be variable, which may in part be owing to the degree of compression applied. However, if the mechanism of action of this treatment could be better understood, it might be possible to improve its efficacy. It is not clear whether assessment of the degree of compression should be made under static or dynamic conditions, or both. A review of methods used previously suggests the need for a new method of assessment allowing continuous monitoring, even during movement. A system for continuous static and dynamic measurements of compression is described. Using an air chamber and manometer to test the system, agreement within +/- 3 mmHg is observed. The system is applied to investigate changes in forces, expressed as pressure, under bandages and compression stockings. Application of five bandage systems by experienced nurses to a volunteer shows a marked variation in applied pressure. During short periods of walking, rapid changes in pressure under compression stockings are observed, including some transients of less than 0.25 s. The method is simple to apply and may help to understand further the mechanism of action of compression therapy.

[The effect of compression therapy on the microcirculation of the skin in patients with chronic venous insufficiency (CVI)].

Compression therapy was employed for 4 weeks 20 patients with chronic venous insufficiency stage CVI I and CVI II according to Widmer's classification. Compression bandaging for 2 weeks was followed by compression stockings for 2 more weeks. The cutaneous microcirculation was evaluated before therapy, after 2 weeks and after finishing compression therapy after 4 weeks. Marked improvement in symptoms such as pain and itching was observed after 4 weeks, along with a significant reduction in lower limb volume. Video capillary microscopy revealed an increase in capillary density associated with a decrease in capillary diameter and pericapillary halo diameter. Compression treatment achieves at least part of its effect by improving the function of the skin microcirculation. The efficacy of bandaging and stockings was similar.

[Modification of proprioceptive ability of knee joints with primary gonarthrosis].

In the study presented, knee joint proprioception of 17 patients with primary degenerative joint disease of the knee joint was evaluated. As a control group, the proprioception of 30 healthy volunteers with clinical and anamnestically inconspicuous knee joints was examined. We tested the proprioceptive capability of the subjects with an angle reproduction test. Additionally, all knee joints were measured with and without an elastic knee bandage. The study showed significantly more deterioration in knee joint proprioception in patients with gonarthrosis than in the control group. Even the proprioception of the contralateral, healthy knee joint was worse than the results of the control group. However, after using an elastic knee bandage, significant improvement in the proprioceptive abilities of the injured knee joint was documented.

[Clubfoot orthosis with integrated dynamic cuff for retention and redressing].

Conservative treatment of clubfoot deformities with braces and bandages is traditionally several hundred years old. The clubfoot braces of Venel, Scarpa, and Schulthess, as well as the redressing bandage of Cheselden, are reviewed as typical examples. The treatment of clubfoot deformities was initiated in the Balgrist Hospital for Orthopedic Surgery by W. Schulthess. Recently, in Balgrist, we developed a brace that retains and redresses the foot. This brace is described, and early clinical results are reported.

No benefit of bracing on the early outcome after anterior cruciate ligament reconstruction.

Forty patients were prospectively investigated to evaluate the effects of bandaging after reconstructive surgery of the anterior cruciate ligament (ACL). For the 6 weeks of the postoperative course, the operated knee was bandaged in 20 patients (group A) and braced in the other 20 patients (group B). The isokinetic torque for extension and flexion (Cybex) and the range of motion (ROM) were investigated after 6, 12, 24 and 52 weeks postoperatively. At 24 weeks and 1 year postoperatively the stability of the knee joint (KT-1000) as well as the clinical outcome ('Orthopädische Arbeitsgemeinschaft Knie') were evaluated. No statistically significant differences between the two groups were found for the extension and flexion strengths. Free ROM was achieved significantly earlier in group A than in group B. No statistically significant differences regarding the stability of the operated knee joint nor the early outcome were found between the two groups. This study demonstrated that the renunciation of using a brace had no adverse effect on the early outcome with respect to stability and function. On the contrary, bracing seems not to be mandatory after ACL reconstruction when the central third of the patellar tendon is used.

Exsanguination of the limbs in elderly volunteers.

We have evaluated the efficiency of exsanguination of the limbs in ten volunteers with a median age of 83 (range 76-86) years using Esmarch bandage or simple elevation. Changes in blood volume were evaluated using a scintigraphic technique based on an autologous injection of 99 mTc-labelled erythrocytes. In both upper (P<0.001) and lower (P<0.001) limbs, Esmarch bandage was significantly more effective than elevation. In lower limbs, there was a significant difference in reduction of blood volume between 5 s and 15 s of elevation (P<0.01).

Canine-specific STR typing of saliva traces on dog bite wounds.

Forensic investigations in dog attacks usually involve the examination of bite marks and toothprints, the dog's stomach and pathological methods. For identification of the offending dog we evaluated canine STR typing of saliva traces on dog bite marks. The specificity of 15 canine-specific STRs was tested on human-canine DNA mixtures prior to an applied study in which 52 cases of dog bites were investigated. The first-aid wound bandages as well as swab samples from the surrounding area of the wound were used for DNA analyses. Generally, it was possible to obtain a canine-specific STR profile from the dog's saliva left on the wound area, even when high background of human DNA was present (blood). Interestingly, we found canine STR typing to be more successful when the bandages and swabs showed high amounts of human blood, i.e. when the dog bite was severe. Canine saliva was then sometimes visible as white-coloured secretion on the human blood surface. Less severe bite cases, which did not result in bleeding wounds, showed less success in obtaining useful STR results, probably due to the fact that the surface of the wounds may have been treated before the victims consulted medical aid which therefore removed the canine cells.

Design and evaluation of a device for measurement of interface pressure.

An electropneumatic device has been designed to measure the interface pressure profile under compression bandages. The device uses commercially available pneumatic sensors (Talley Group Ltd, SJ235/3) and measures interface pressure at up to eight sites simultaneously along the lower limb, with an accuracy of +/- 3 mmHg. Measurements can be made in one of two modes: continuously at a rate of up to three samples per second with the results output to a suitable display device, or single measurements of interface pressure can be made and displayed on a digital display incorporated in the device. This enables the monitoring and recording of interface pressure under compression bandages during either ambulation or passive recumbency. The electropneumatic system is described together with its following characteristics: the hysteresis of the Talley pneumatic sensors, the accuracy of pressure measurement and the maximum achievable sample rate. Dynamic measurements in a single normal volunteer are shown.

Biosoluble surgical material from 2,3-dialdehyde cellulose.

Dialdehyde cellulose (DAC) was prepared by periodate oxidation of various cellulosic materials in the form of sutures and bandages. The suitability of using DAC for making bioabsorbable sutures and antimicrobial wound dressing bandages was studied. The investigations indicated that DAC combines the requisite mechanical strength with an inherent antimicrobial nature. It was found that the oxidation of cellulose to yield DAC also rendered it bioabsorbable. The DAC was coated with different concentrations of urea formaldehyde in order to improve the mechanical properties for making sutures.

Histological and bacteriological studies of burn wounds treated with boiled potato peel dressings.

Histological and clinical studies have been made on comparable burn wounds covered with either boiled potato peels affixed to gauze bandages or gauze dressings alone; both dressings were applied over a thin layer of 5 per cent silver sulphadiazine. Compared with treatment with plain gauze dressings, the application of the potato peel dressing reduced or eliminated dessication, permitted the survival of superficial skin cells and hastened epithelial regeneration. Bacteriological studies showed that the potato peels had no intrinsic antibacterial activity, the wounds beneath both dressings showing either no growth or, on most occasions, the same bacterial species. The easy availability of potato peels and gauze bandages on to which they can be affixed, the simplicity of the preparation of this dressing, the ease of sterilization and its low cost of production make this the dressing of choice for burn wounds in our developing country.

A technique of haemostasis of the extremities after debridement of burn wounds.

A technique used to achieve prompt haemostasis in burned wounds of the extremities is described. After tangential debridement using a tourniquet, thrombin solution (1000 units in 1 ml of saline solution) is applied on the entire wound. Immediately after removing the tourniquet; the wound is tightly wrapped with a thin plastic film and a pressure bandage over the entire wound. The pressure bandage is kept on for approximately 10 min after removing the tourniquet. With this procedure, haemostasis of the capillary oozing can be promptly and completely achieved. Furthermore, arterial and venous haemostasis can also be achieved, with clots present at the arterial and venous haemorrhagic points. As these clots can be removed easily, ligation or electrocoagulation is necessary. This technique is especially useful for haemostasis in a wound of the extremity after tangential excision leading to decreasing blood loss.

External compression dressing versus standard dressing after axillary lymphadenectomy.

BACKGROUND: Closed-catheter drainage after axillary lymph node dissection (ALND) for breast cancer may constitute a significant inconvenience to the recovering patient, and may also serve as portals of entry for bacteria. Any intervention that could reduce the volume and duration of postoperative drainage would be beneficial. The purpose of this study was to determine whether an external compression dressing after ALND would decrease postoperative drainage, afford earlier drain removal, and reduce subsequent seroma formation. PATIENTS AND METHODS: One hundred thirty-five women undergoing definitive surgical treatment for breast cancer were randomized to receive a compression dressing (n = 66) or standard dressing (n = 69). They were also stratified for modified radical mastectomy (MRM; n = 74) or breast conservation therapy (BCT; n = 61). All patients had ALND. The compression dressing consisted of a circumferential chest wrap of two 6-inch Ace bandages, held in place by circumferential Elastoplast bandage, and it was applied by the same nurse. This dressing remained intact until postoperative day 4. Patients in the standard dressing group (control) were fitted with a front-fastening Surgibra only. Drains were removed when the total daily amount was <50 cc. Postoperative drainage volume, total days with drain, and frequency of seroma formation were recorded for each patient. RESULTS: After 4 days, wound drainage in both groups was nearly identical (compression = 490 cc, standard = 517 cc; P = 0.48). Total days with drain were also similar (compression = 6.4 days, standard = 6.1 days; P = 0.69). The compression dressing did not reduce seroma formation. In fact, there was a statistically significant increase in the number of seroma aspirations per patient in the compression group (compression = 2.9, standard = 1.8; P <0.01). The increase in seroma aspirations was more significant in MRM patients (compression = 3.1, standard = 1.7; P <0.01) than in BCT patients (compression = 2.6, standard = 1.8; P = 0.20). CONCLUSIONS: External compression dressing fails to decrease postoperative drainage and may increase the incidence of seroma formation after drain removal. Thus, routine use of a compression dressing to reduce postoperative drainage after ALND for breast cancer is not warranted.

Healing of open stump wounds after vascular below-knee amputation: plaster cast socket with silicone sleeve versus elastic compression.

OBJECTIVE: To assess the effect of a plaster cast socket on the healing of open wounds and on temporary prosthesis fitting after below-knee amputation because of arterial occlusive disease. DESIGN: Randomized controlled trial. SETTING: Rehabilitation center, university hospital. PATIENTS: All included patients had undergone recent (in the previous 3 months) below-knee amputation because of arterial disease and initially had an open stump. Patients were randomly assigned to two groups of 28 subjects each. The sizes of the amputation scars were 8 to 24 cm2. Ischemia of the stump was eliminated as a probable cause of delayed wound healing by the inclusion criterion of transcutaneous oxygen tension (TcPO2) of >35 mmHg. The average age in group I (the experimental group) was 65.2 +/- 12.4 (SD) years and in group II (the control group) 66.8 +/- 10.8 years (not significant). INTERVENTION: A plaster cast (supracondylar-type) socket was fitted on the stumps of group I patients, interposed with a silicone sleeve. The patients were gradually trained to wear this cast for up to 5 hours a day. They were provided with elastic compression bandages for the remainder of the time. Patients in group II wore elastic compression bandages, which were only removed for dressing changes. MAIN OUTCOME MEASURES: Time required for stump healing, length of time between amputation and ability to walk wearing a contact socket, and length of hospital stay. RESULTS: Group I had a quicker average healing time (71.2 +/- 31.7 [SD] days compared to the control group's 96.8 +/- 54.9 days) and a shorter average length of hospital stay (99.8 +/- 22.4 days compared to the control group's 129.9 +/- 48.3 days). CONCLUSION: Use of a plaster cast socket leads to more rapid healing of the open stump and to a shorter hospitalization. If there is no stump ischemia, this plaster cast technique is safe.

[Management of lymphedema: experience of the Cognacq-Jay Hospital].

Treatment of lymphedema includes practical advices, manual lymph drainage, bandaging, self-bandaging, elastic compression garment, skin care and physical exercises. Weight loss may be useful if obesity. Surgery is indicated in genital lymphedema more than in limb lymphedema. In 2001, in Lymphology Unit, 248 women were treated for secondary upper limb lymphedema after breast cancer. Excess of volume of lymphedema was reduced by 31.3% after a mean time of 2.1 weeks. For lower limb lymphedema (primary or secondary), 136 patients were treated with a mean reduction of excess of lymphedema by 29.8% after a mean time of 2.2 weeks. After this treatment, long term follow-up is necessary to maintain results and the motivation of the patient.

Effect of different compression therapies on the reflux in deep veins with a post-thrombotic syndrome.

BACKGROUND: Reflux in deep veins is an important pathophysiological factor of post-thrombotic syndrome which can be demonstrated by colour-coded duplexsonography. This study investigates the effect of different compression therapies on the reflux velocity in deep veins in patients with a post-thrombotic syndrome. PATIENTS AND METHODS: Sixty patients with a post-thrombotic syndrome-confirmed by phlebography, in the deep veins of the calf and the thigh were investigated in two groups: In group A, 30 patients (mean age 58 +/- 10 years) received compression stockings (calf compression class II and III, thigh compression class II) and in group B 30 patients (mean age 58 +/- 14 years) received a Sigg short traction bandage of the calf. The velocity at the time of the greatest reflux in the popliteal vein was determined as reflux parameter with the colour-coded duplex sonography using a cuff applied at the calf. All patients stood upright and were measured with and without different kinds of compression therapies. The reflux velocities were graded as low, moderate and high. RESULTS: A significant decrease of the reflux velocity by about more than 45% with compression therapy was found in both groups. The decrease of the refluxes in group A (mean 47.9%) did not differ significantly from the decrease of refluxes in group B (mean 55.8%). The greatest decrease of the reflux velocity under compression therapy was found in high-grade refluxes in both groups. CONCLUSION: A significant decrease of the reflux velocity in post-thrombotic syndrome can be readily demonstrated with different kinds of compression stockings as well as with bandages by means of colour-coded duplex sonography.

Interface pressure under a ready made compression stocking developed for the treatment of venous ulcers over a period of six weeks.

BACKGROUND: The most important component in the treatment of venous ulcers is compression therapy. The function of compression therapy is the pressure exterted on the extrafascial and intrafascial venous system. Therefore the interface pressure of specially designed compressions stockings for the treatment of venous ulcers are in the focus of interest. PATIENTS AND METHODS: We examined 20 patients (6 men and 14 women) with chronic venous insufficiency in CEAP stages CS0-4EPAS1-3PR). Interface pressure was measured under the Venotrain Ulcertec over an observation period of six weeks with piezoresistance sensors at four different sites on the lower leg and with the patient in different body positions. RESULTS: Resting pressure supine at the ankle corresponded to compression class III and was constant over the period of six weeks (mean difference 2.8 SD 15.3 mmHg, p = 0.49). Working pressure explained as the quotient of maximum pressure during tiptoing/resting pressure in standing position was initially at the ankle 1.70 SD 0.44 and after 6 weeks 1.44 SD 0.29 (mean difference 0.27 SD 0.42, p < 0.03). CONCLUSIONS: The compression stocking maintained a therapeutically effective pressure profile over a period of six weeks. Working interface pressure was comparable to that of short-stretch compression bandages applied by an experienced bandager immediately after application.

National survey of corneal abrasion treatment.

PURPOSE: To survey the different methods used in the management of corneal abrasions (including iatrongenic cases) nationally. METHOD: A questionnaire survey of all 162 ophthalmic units in the UK was carried out in 1997. RESULTS: The response rate was 134 of 162 (83%). The majority of units do not have an established policy for the treatment of corneal abrasions. Topical antibiotic alone and antibiotic together with a cycloplegic are the commonest immediate treatments, whilst the most common treatment course is topical antibiotic. Padding and patient follow-up is practised some of the time by most units and all of the time by the remaining minority. Use of a soft bandage contact lens is uncommon. There is no statistically significant difference (p > 0.05) between the policy-holders and non-policy-holders in their use of the various topical regimes, padding and soft bandage contact lens. CONCLUSION: The traditional trio of topical antibiotic, cycloplegic and padding is still the mainstay of corneal abrasion treatment amongst units nation-wide. However, there is a lack of reproducible scientific evidence to support this treatment. Larger randomised trials looking at the efficacy of the different treatment options are needed.

Pathergic pyoderma gangrenosum in a venous ulcer.

A 74-year-old woman was referred to our department in December 1999 for a pyoderma gangrenosum (PG) arising at the edges of chronic leg ulcer. The history was positive for benign monoclonal gammopathy, ischemic hypertensive cardiopathy, polyarthrosis and venous lower leg deficiency. Monoclonal gammopathy of IgA Kappa type was diagnosed 10 years before with a continued benign nature. In 1990 a post traumatic PG of the left leg was diagnosed and a therapy with Cyclosporine A was started with healing of the lesion. In June 1999, 6 months before the hospitalization, a typical venous ulcer of the right leg appeared and was treated with bed-rest, compression bandaging and topical desloughing therapy. In the last month, after a minor surgical debridement of the wound, the lesion developed pustules evolving into a painful, necrotic ulcer with ragged, purple-red, undetermined borders (Fig. 1). A relapse of PG was suspected. Histological examination was consistent with pyoderma gangrenosum and showed massive neutrophilic infiltration, hemorrhage and necrosis of the overlying epidermis. Wound culture was negative. Other laboratory examinations only showed IgA = 8.15 g/L. Investigation of other underlying medical conditions were normal or negative. The venous leg ulcer gradually healed with antiseptic and compression-bandage therapy. After a 4-month course of topical steroid therapy with good results, the PG recurred also involving the proximal area of the leg. Methylprednisolone 50 mg/day was started. Healing began 10 days later and 2 months later the wound healed and epithelialized. Steroid was reduce to 5 mg daily for 4 months. No recurrence was seen when the drug was stopped.
