A study of collagen dressing versus conventional dressings in burns at tertiary health care centre

Background: Worldwide, burn injury is a problem and cause intense pain, biological dressings like collagen as it forms physiological interface prevents infection effective for burn wound healing. The objective of the study was to study of collagen dressing versus conventional dressings in burns at tertiary health care centre.Methods: This was a cross sectional study carried out in the Department of Surgery during September 2018 to September 2019. Out of 50 patients, 25 were enrolled to collagen treatment group (group A) and remaining into conventional treatment group i.e. (group B). The statistical analysis was done by unpaired t-test and chi-square test.Results: Average less time required for granulation tissue to appear p<0.001, df=48, t=4.56); average less time requires for sterile wound swab culture (weeks) (p<0.05, df=48, t=3.45); less discomfort score (0-10) (p<0.001, df=48, t=6.78); less dressing removal pain score (0-10) (p<0.0001, df=48, t=9.87); less average time required for complete healing (days ) (p<0.001, df=48, t=7.79).Conclusions: It can be concluded that collagen dressings were superior to conventional dressing in wound healing of burns.

A comprehensive study on effect of collagen dressing in diabetic foot ulcer

Introduction: Wounds can cause painful lengthy hospital stay, multiple stages of surgeries, and enormous financial burden. Biological dressing’s collagen granule dressing has advantage over conventional dressing in terms of non-immunogenic, non-pyrogenic, being natural, easy application and decreased days of healing. Objectives: To compare the efficacy and safety of collagen granule dressings and conventional dressing in diabetic wounds in terms of reduced healing time, number of dressing, healing quality and complications Materials and methods: A prospective study was done in which 30 patients who presented with diabetic wounds were chosen by random sampling technique, and were grouped into 2 groups consisting of 15 patients. Thirty patients with foot ulcer were evaluated. A collagen or conventional dressings were applied, and the patients were followed as per standard post-application treatment protocol. Patients underwent dressing changes every day until wound healing or for maximum period of 12 weeks. Changes in wound size were recorded when the dressing was removed; and at 4 and 12 weeks. Conclusions: Our study is a hospital based case control prospective study done in 30 patients of chronic diabetic foot ulcers. There was statistically significant difference between the results of collagen and saline dressings as collagen dressings had better healing response rate as compared to placebo when given along with standard treatment of diabetic foot ulcer.

A clinical observation of 107 cases of collagen dressing in treatment of facial hormone dependent dermatitis / 中国生化药物杂志

Objective To investigate clinical effect of collagen dressing in treatment of facial hormone dependent dermatitis.Methods 107 patients were divided randomly into treatment group and control group.53 cases of control group were given citrate desloratadine,ompound glycyrrhizin tablets, 0.3% tacrolimus ointment, cod liver oil ointment for 4 weeks.54 cases of treatment group were given collagen dressing 25 minutesper night, based on control group.After 4 weeks of drug treatment,treatment group continued to be given collagen dressing once every other night, control group were given cod liver oil ointment twice a day, morning and night.Both groups continued to observe for 12 weeks, at the same time, 0.3% tacrolimus ointment was given once every other day.Compared effect of two groups in the short-term and long-term.Results There were no significant differences in symptom scores between the two groups pre-treatment; compared with pre-treatment,the symptom scores were decreased(P<0.05).Compared with control group, the symptoms of treatment group were lower than that of treatment group(P<0.05).Compared with control group, the clinical total effective rate was higher than treatment group ( P<0.05 ) .Conclusion The collagen dressing can improve the facial treatment of hormone-dependent dermatitis.

The clinical observation of high-energy red fight combined with human-like collagen dressing in treatment of facial corticosteroid addictive dermatitis / 中国医师进修杂志

Objective To observe the efficacy of high-energy red light combined with human-like collagen dressing in treatment of facial corticosteroid addictive dermatitis.Methods Eighty-three patients with facial corticosteroid addictive dermatitis were divided into treatment group (42 cases) and control group (41 cases) by random digits table method.All patients in 2 groups were treated with ebastine 10 mg,once a day,and vitamin E cream,twice a day.At the same time,the patients in control group were given human-like collagen dressing,once a day in the first week,then 3 times/week.On the basis of control treatment,the patients in treatment group were irradiated with high-energy red light 10 min in face,2-3 times/week.The treatment of both groups lasted for 12 weeks.The symptoms,skin lesions and untoward reaction were observed after treatment of 4,8 and 12 weeks.Results After treatment of 4 weeks,there was no statistical difference in the effective rate between 2 groups (P ＞ 0.05).After treatment of 8 and 12 weeks,the effective rates in treatment group were significantly higher than those in control group [83.3％(35/42) vs.58.5％ (24/41),90.5％ (38/42) vs.65.9％ (27/41)],there were statistical differences (P ＜ 0.05).No untoward reaction was found in 2 groups.Conclusion High-energy red light combined with human-like collagen dressing is effective and safe in treatment of facial corticosteroid addictive dermatitis.

Treatment of Deep Second Degree Burn Wound using Heterogenic Type I Collagen Dressing

PURPOSE: The purpose of this study is to evaluate the effectiveness and validity of the wound dressing using heterogenic type I collagen dressing (Collaheal(R)). METHODS: From January 2010 to April 2010, 46 burn patients with deep second degree or third degree burn wound were treated with Collaheal(R). And we followed up the patients to assess the treatment result with Vancouver scar scale after 6 months. RESULTS: Of the 46 patients, 42 patients had deep second degree burn only and 4 patients had deep second degree burn with third degree burn. It took 18.5 days to re-epithelialize for patients with deep second degree burn and 40.5 days for third degree burn wound. After 6 months, follow-up was performed to assess the wound result. We can observe that 24 patients had mild scar and 5 patients had moderate scar and 2 patients had severe scar. The severity of scar increased as the re-epithelialization period increased. CONCLUSION: It took 18.5 days to re-epithelialize the deep second degree burn wound with collagen dressing. And the long term result was good. Type I collagen dressing can be used for treatment option for the patients with deep second degree burn wound and the patients with small third degree burn wound who cannot be operated.

Diabetic Ulcers Treated with Bi-layered Collagen Membrane / 대한피부과학회지

Diabetic foot ulcer is a serious clinical problem with significant medical and economic effects on health systems worldwide. Some patients undergo amputation and others experience disability for an extended period of time. Treatment of diabetic foot ulcer is complex and difficult. Even with proper management, the wounds may not heal as well as expected. To promote wound healing, many advanced topical dressing materials have been developed. Among them, bi-layered collagen membrane, which is composed of collagen and hyaluronic acid, is believed to enhance wound healing. Herein we report two cases of diabetic foot ulcer which were successfully treated using bi-layered collagen membranes.
