Diabetic foot ulcer (DF) is a chronic complication of diabetes mellitus (DM), which impact on the morbidity, mortality and quality of patients’ lives.Of those patients with diabetes mellitus, approximately 15% to 25% developed to the foot ulcer. Beside has the infection and debridement of devitalized tissue downloading; the moisture imbalance becomes the factors of recalcitrant to healing. Moist wound healing is often contraindicated to the non-healable wounds. While wound care involves the debridement, bacterial reduction, and moisture balance in order to achieve the good granulation of the tissue development and adequate blood supply.

Wound healing is a perfectly coordinated cascade of cellular, molecular, and biochemical events which interact in tissue reconstitution. Chronic diseases such as pressure ulcers (PU) and diabetes mellitus (DM) are considered risk factors for wound healing. Patients with such diseases often have higher sepsis, infection, and complication rates, since they have revascularization inhibition and low growth factor expression. Thus, latex biomembrane (LBM), a biocompatible material, derived from the latex of the rubber tree (Hevea brasiliensis) appears to create tendencies as an angiogenic-inducing tissue healing agent and as biomaterial, resulting from its structural qualities and its low cost when compared to conventional treatments. Therefore, this work aims at summarizing the results, experiments, and scientific findings that certify or recommend the use of LBM as a new technique to be applied effectively in the treatment of wounds. An integrative review was held in the BIREME, LILACS, Burns, MEDLINE, PubMed, and SciELO databases, from 2000 to 2016, using the following descriptors: “healing,” “diabetes mellitus,” “wounds,” and “latex membrane.” As a result, 600 experiments (out of 612) presented satisfactory results; however, 33% of the cases received explicit recommendations, 11% required more studies on the subjects, and 1% was denied. On the other hand, half of the studies did not expressly endorse its use, despite presenting satisfactory results. The LBM was characterized as a good therapeutic alternative in cases of wounds, including chronic diseases, such as diabetes mellitus and PU, due to its relevant potential for wound healing stimulation, acceleration of cell tissue mending and revascularization, or the reestablishment of angiogenic functions (creation of new blood vessels). The LBM was also confirmed to be safe as a biocompatible material whose structural qualities (elasticity, adaptability, impermeability, and possibility of suture), devoid of toxicity, allowed interaction between tissues and presented no hypersensitivity inducer and no antimicrobial effect.

Diabetes mellitus (DM) is one of the most common chronic diseases experienced by the world population and ranks fourth cause of death in developing countries. Long-term complications of diabetes mellitus one of them is diabetic ulcer (15%) and is the most cause (85%) of amputation in patients with diabetes mellitus. Currently, more than 5,000 modern types of dressings are reported to be available to treat wounds, especially diabetic ulcers. To know the process of wound healing diabetic ulcer was done with the design of case study research with a sample of 2 people and this study was conducted for 4 weeks. The study was conducted at the Maitis Efrans Wound Care clinic in Bengkulu City. The result was obtained that the assessment of diabetic ulcer wounds before modern wound care on the respondents was a total score of 54 and the respondents two total score of 50 were stated wound regeneration. The healing process of the responder's second ulcers progressed, the total score of one respondent was 30 and the respondent two was 28. Respondents. Progress on the two respondents stated better influenced by wound healing factor that is, age factor.

ABSTRACT Background: Chronic wounds in patients with Diabetes Mellitus often become incurable due to prolonged and excessive production of inflammatory cytokines. The use of probiotics modifies the intestinal microbiota and modulates inflammatory reactions. Aim: To evaluate the influence of perioperative supplementation with probiotics in the cutaneous healing process in diabetic rats. Methods: Forty-six rats were divided into four groups (C3, P3, C10, P10) according to the treatment (P=probiotic or C=control, both orally administered) and day of euthanasia, 3rd or 10th postoperative days. All rats were induced to Diabetes Mellitus 72 h before starting the experiment with alloxan. Supplementation was initiated five days before the incision and maintained until euthanasia. Scalpel incision was guided by a 2x2 cm mold and the wounds were left to heal per second-intention. The wounds were digitally measured. Collagen densitometry was done with Picrosirius Red staining. Histological parameters were analyzed by staining by H&E. Results: The contraction of the wound was faster in the P10 group which resulted in a smaller scar area (p=0.011). There was an increase in type I collagen deposition from the 3rd to the 10th postoperative day in the probiotic groups (p=0.016), which did not occur in the control group (p=0.487). The histological analysis showed a better degree of healing in the P10 group (p=0.005), with fewer polymorphonuclear (p<0.001) and more neovessels (p=0.001). Conclusions: Perioperative supplementation of probiotics stimulates skin wound healing in diabetic rats, possibly due to attenuation of the inflammatory response and increased neovascularization and type I collagen deposition.

Diabetes mellitus is a common condition in the general population, and particularly so among hospital inpatients. Complications associated with diabetes mellitus further increase its incidence in surgical patients, particularly those requiring vascular, renal, or ophthalmic procedures. Patients with diabetes have a higher rate of morbidity and mortality associated with surgery. This includes cardiovascular and renal complications, infection, and impaired wound healing. The process of surgery, a controlled form of trauma, provokes a metabolic response due to the release of cytokines and stress-associated hormones. These agents promote a catabolic state that includes increased insulin resistance. The resulting hyperglycaemia leads to overflow of substrates in the mitochondria and the generation of excess free oxygen radicals, which can be toxic to the cell. It should, therefore, be possible to reduce these effects by avoiding or attenuating the stress response and/or counteracting its metabolic effects. The stress response is proportional to the degree of tissue trauma. Insulin administration and normoglycaemia have been shown to reverse catabolic changes and improve wound healing and skin grafting, and also to reduce the incidence of infective complications. Additionally, the stress response may be, in part, attenuated by the choice of anaesthetic technique. Neuraxial (spinal and epidural local anaesthetic) analgesia can reduce sympathetic nervous system tone and adrenal output. Additionally, much ophthalmic surgery is now performed with local anaesthesia techniques. Such approaches avoid the more prolonged starvation and cardiorespiratory risks associated with general anaesthesia.

In the critically ill patient, wound repair can be impeded by processes inherent to the illness, its treatment, and the critical care environment. This vulnerability to wound complications increases patient morbidity and mortality as well as length of stay, resource consumption, and hospital cost. The physiology of wound healing and factors that impede wound repair are discussed. Those factors commonly seen in critical illness include advanced age, diabetes mellitus, compromised immunocompetence, inadequate perfusion, and oxygenation, infection, malnutrition, obesity, and preoperative illness. Knowledge of management of the physiologic factors that affect wound healing enables the nurse to maximize tissue repair and prevent wound complications
