Background and study aims
Chronic ulcers are defined as ulcers that do not heal in six to nine weeks.This type of ulcer is a big health problem all over the world, affecting the life of patients and the health care system. Wound dressings based on a dense fibrillary network (fibers) made of biosynthetic cellulose (BC), such as eiratex® have been proposed to be a good alternative to the different types of dressings that are currently used to treat this type of ulcers. This is due to their similarity to collagen in skin (the protein in the skin that gives skin strength and elasticity). However, traditional BC has been problematic on infected ulcers since fluids as exudate can be trapped under the dressing. The aim of this study is to examine if a wound dressing based on eiratex® can facilitate the healing of the wound and overcome the problems related to the use of the traditional BC.
Who can participate?
Adults aged 62 to 85 who have a chronic lower limb wound (ulcer) that has not healed after six weeks.
What does the study involve?
Participants are treated with the eiratex®-based wound dressing. The dressing is applied on the ulcers after surgical removal of the damaged area or tissue, when applicable. The wounds are examined every second day by the attending physician during the first week, and then once per week until final healing. When the wound started to heal, the dressing should be found to adhere to the wound, typically within two days from the start of treatment. In case of lack of improvement of the wound healing, a new debridement was carried out and a new eiratex® membrane was applied to the wound. Once the dressing adhered it is not removed from the wound until it spontaneously fell off. An examination by the attending physician is then performed to assess wound healing.
What are the possible benefits and risks of participating?
There are no benefits or risks with participating.

Scientific title | A clinical trial on patients with non-healing ulcers treated with a modified version of a biosynthetic cellulose named eiratex: Effects on the healing rate, healing time and treatment costs compared to a saline-soaked gauze and other wound dressings. |
Study objectives | Wound dressing based on eiratex® could facilitate the healing of the wound and overcome the problems related to the use of the traditional BC. |
Ethics approval(s) | As the the product is registed in registered in Sweden as medical device and is CE-marked, according to Swedish law, ethical approval is not necessary for the study. The study itself was not an experimental procedure.The patients were treated and their follow-up data collected only after informed consent. All patient information was blinded so that no information can be back traced to individual patients. |
Health condition(s) or problem(s) studied | Patients with chronic lower-extremity venous ulcers or traumatic ulcers were object of this trial |
Intervention | The eiratex® dressing was applied on the wound after surgical debridement, where applicable. The wounds are examined every second day by the attending physician during the first week, and then once per week until final healing. When the wound started to heal, the dressing was found to adhere to the wound, typically within two days from initiation of treatment. In case of lack of improvement of the wound healing, a new debridement was carried out and a new eiratex® membrane was applied to the wound. In three patients clinical signs of infection were seen. Once the dressing adhered it was not removed from the wound until it spontaneously fell off. An examination by the attending physician was then performed to assess wound healing. At each treatment visit, information regarding adverse events, medications and other aspects of care since the last visit was acquired. All wounds were photographed before treatment and at each follow-up visit after treatment. |
Intervention type | Procedure/Surgery |
Primary outcome measure | Healing time is measured by visual examination from the medical doctor. At each treatment visit, information regarding adverse events, medications and other aspects of care since the last visit was acquired. |
Secondary outcome measures | 1. Frequency of dressing changes are measured by counting the total number of dressings used during the treatment for each patient, divided by the healing time (in weeks) 2. Number of dressings used are measured by the doctor for each patient. The number of dressings used is related to the number needed to heal the wound |
