| Scientific title | Effectiveness of acupuncture, special dressings and simple, low-adherence dressings for healing venous leg ulcers in primary healthcare: Study protocol for a cluster-randomised controlled clinical trial |
| Study objectives | The combination of compression bandaging with simple, low-adherence dressings and acupuncture is more effective than when the same bandaging is employed in combination with special dressings or with simple, low-adherence dressings, but no sensory stimulation (acupuncture), with respect to the complete healing of venous leg ulcers. |
| Ethics approval(s) | Andalusian Government Committee for Clinical Trials, Spain. Date of approval: 08/05/2007 (ref: acta 03/07) |
| Health condition(s) or problem(s) studied | Venous leg ulcer |
| Intervention | The participating primary healthcare centres will be randomly allocated to the following three groups: Group A: Compression therapy + low-adherence, simple dressings + acupuncture Group B: Compression therapy + special dressings Group C: Compression therapy + low-adherence, simple dressings Compression therapy (Groups A, B and C): Compression therapy will be given to all the participants in the study. Once the patient has been examined and the ankle/arm index calculated by means of a Doppler scan, an evaluation will be made of the state of the skin and of the shape of the leg, after confirming the absence of neuropathology, arterial pathology and cardiac insufficiency. The bandaging will be of a class 3, high-compression multilayer type, following cleansing and application of the dressing, as follows: 1. With a 50% overlap, apply a cotton bandage in a spiral pattern from the base of the toes to just below the knee, without imposing any tension 2. Apply an elastic bandage in a spiral pattern, with 50% overlap and stretched to 50% of its extension, from the base of the toes to just below the knee 3. Apply a cohesive elastic bandage, with 50% overlap and stretched to 50% of its extension, from the base of the toes to just below the knee, and apply light pressure to ensure the adherence of the bandage. The oedema of the leg should be reduced by raising the limb for 15 minutes before applying compression. Cleansing of the ulcer for the patients given low-adherence, simple dressings (Groups A and C): 1. Cleaning: with running water and mild soap, followed by careful drying 2. Debridement: if necrotic tissue or sloughing are observed, perform enzymatic debridement, which may be combined with excision debridement, if necessary 3. Managing infection: if infection is suspected, take a sample and begin treatment with Silvederma® for a maximum of 2 weeks. If a culture study confirms the infection, treat using oral antibiotics 4. Dressings: simple, low-adherence type (paraffin-impregnated tulle gras) Topical treatment of the ulcer for the patients given special dressings (Group B): 1. Cleaning: with running water and mild soap, followed by careful drying 2. Debridement: if necrotic tissue or sloughing are observed, perform enzymatic debridement, which may be combined with hydrogel to favour autolysis. If necessary, excision debridement should be applied. 3. Managing infection: if infection is suspected, take a sample and begin treatment with silver dressings (hydrofibre or hydropolymer) for a maximum of 2 weeks. If a culture study confirms the infection, treat using oral antibiotics. 4. Dressings: Cover with hydropolymers. Use alginate or hydrofibre dressings if exudate must be controlled. Sensory stimulation by acupuncture (Group A): The nursing staff will be trained in the specific techniques of localisation, puncture and manipulation in order to apply acupuncture at the perilesional zone of the ulcer(s), in healthy skin, using 4-8 needles, and at 2 points located on either side of the tibial crest of the affected limb (Yinlingquan SP9 and Zusanli ST36). The sensorial stimulation sessions will be applied for the first 3 months of this treatment programme or until the ulcer has completely healed. If complete healing is not achieved in this period, the sessions may be prolonged for another 3 months, after which the sensorial stimulation treatment will be discontinued. For each session, the number of needles used and the exact location of their application will be recorded. A priori, the ulcer should be cleansed once weekly, the same frequency as the sensorial stimulation. Nevertheless, this may be increased or decreased, at the discretion of the nursing staff. Duration of interventions: Interventions will continue until the ulcer is completely cured, except acupuncture which may be prolonged up to 6 months (maximum). Total duration of follow-up: 12 months |
