Venous ulcers are one of the public problems in the world at present, which has a great impact on human life and spirit. Therefore, this paper explores the therapeutic effect of the compression therapy guided by Unna boots on patients with lower limb venous ulcers. A total of 90 venous ulcers patients who were treated in our hospital from June 2016 to June 2019 were collected, the patients received the compression therapy guided by Unna boots, and the Unna boots were replaced every two w for 3 mo. The ulcer area and cure rate of the patients before and after treatment were evaluated, and the changes of quality in life and mental state of the patients were evaluated by the mean opinion score item short from health survey (SF-36). After one mo of treatment, the cure rate of the patient was 61.11 %, the focus showed epithelialization, and the cure rate reached 91.11 % after 3 mo. The results of the SF-36 survey showed that the average score of patients increased to 57.80 after one mo of treatment and to 75.66 after three mo of treatment. At the same time, the physical function and general health scores of all patients were significantly improved after 3 mo of treatment. Before treatment, the average scores of social communication, role-emotional, and mental health in all patients were lower. After one mo of treatment, the average score of these evaluation indexes gradually increased. After 3 mo of treatment, the average score of these evaluation indexes was 4 times higher than that before treatment, and the difference before and after treatment was significant (p<0.05). The results show that the compression therapy guided by Unna boots is effective in the treatment of lower limb venous ulcers, which can not only improve the quality of life of patients, but also help patients to restore self-confidence and self-esteem, and contribute to the recovery of patients.

Many Venous ulcers (VUL) were a major public health problem in the world. Because of its high incidence, it has a great impact on the social economy . VUL was a skin lesion that affects 1/3 of the lower legs, accounting for about 70 %-90 % of all leg ulcer cases. VUL was associated with the chronic venous insufficiency, which was the main cause of leg ulcers. This venous insufficiency was common in the elderly . VUL makes the patients lose productivity and retire with disability due to unbearable pain. Some studies have found that in addition to restricting the patients daily life and leisure activities, VUL may also damage the patient’s quality of life (QoL) and self-esteem, and even lead to depression . When the wound appears, the movement of the patients was limited and the pain was unbearable. In addition, the exudate and smell of the wound will affect the patient’s way of life. Because some wounds may take several mo to heal , the patients often feel frustrated and hopeless about the treatment. Compression therapy was often carried out with a stretch hose, bandages, pressure bandages or Unna boots, which was an effective means of VUL treatment . As the pressure exerted on the leg moves from the ankle to the knee, its intensity gradually decreases, and the hydrostatic pressure of the intravascular increases, thus reversing the adverse consequences of standing for a long time [6,7]. In 40-95 % cases, compression therapy can cure VUL completely, and improve the QoL and functional status of VUL patients [7-11]. Even the compression therapy can also promote the healing of VUL, prevent a recurrence, and improve the QoL, selfesteem, and well-being. However, the therapeutic effect of Unna boots on patients has not been reported. Therefore, in this study, Unna boots were used to treat patients and its therapeutic effect and psychological changes were analyzed. A total of 90 patients with VUL treated in our hospital from June 2016 to June 2019 were collected. Inclusion criteria: the age of the patients were more than 18 y old and had ulcers for at least 1 y. The ankle brachial index (ABI) was between 0.8-1.0. Classified according to tissue type and exudate. Exclusion criteria: the patients had arterial ulcer of lower extremities, systemic important organ failure, diabetes, and severe cognitive impairment. All the patients were given basic treatment: debridement of the wound and surrounding skin with An’erdian III disinfectant, then local cleaning with 0.9 % chloride cotton ball. However, povidine iodine antiseptic solution can also be used to clean the wound which is believed to be more efficacious, thus main the wound sterile. Gently remove the soft necrotic tissue from the wound with forceps, tweezers or scissors, and dry with sterile gauze. The ulcer wound was treated with calcium sodium alginate dressing, covered with the aseptic application and fixed with adhesive tape. Unna boots were used to guide compression therapy, and replaced every 2 w. This study lasted for 3 mo. The data were collected on the d of the patient visit, 1 mo later, 3 mo later, and the follow-up period (4th mo later). According to the existing evaluation survey scheme, the MOS item short from health survey (SF-36) was used to evaluate QoL . SF-36 was a general, multi-dimensional health survey, consisting of 36 questions, covering 6 areas: physical function, physical pain, general health, social communication, role-emotional, and mental health. The specific details were as follows: The physical function mainly assesses how the individuals perform tasks, such as dressing, bathing, walking, and climbing stairs; The physical pain mainly assesses the pain an individual has experienced during the assessment, as well as the limitations of symptoms on the patients daily life; The general health status mainly assesses how individuals view their own health and their views on the future health; The social communication mainly assesses how the emotional health affects work and other daily activities; The role-emotion mainly assesses the normal social activities time give up by the patients because of their physical or emotional state; The mental health mainly assesses the damage to life caused by anxiety, depression, happiness, calmness and other emotions. All patients in the study were independently evaluated and scored. 0 means extremely unhealthy, 100 means very healthy, and the higher the score, the better the health. SPSS 20.0 was used for statistical analysis, the measurement data was expressed by (x±s) and analyzed by the t-test, and the counting data were analyzed by χ2 test. p<0.05 means the difference was statistically significant. Among the selected 90 patients, 62 patients (68.89 %) were older than 60 y old, 48 females (53.33 %) and 63 retirees (70 %) Table 1. Before treatment, the area of ulcer ranged from 16-20 cm2. One mo after the compression therapy with unna boots, the lesions of 55 patients (61.11 %) was epithelialized. And three mo later, 82 patients (91.11 %) were cured, the difference was statistically significant (p<0.05, fig. 1). Before treatment, the average SF-36 score of the patients was low, which was only 16.50. After one mo of treatment, the average score increased to 57.80. After 3 mo of treatment, the average score increased to 75.66 (fig. 2). The difference before and after treatment was statistically significant (p<0.05), indicating that the QoL of these patients was significantly improved. Before treatment, the average scores of physical function and general health in all patients were lower, while the physical pain scores were significantly higher (fig. 3). After 3 mo of treatment, the average scores of these evaluation indexes were significantly improved (p<0.05), indicating that the symptoms and QoL of these patients were significantly improved. Before treatment, the average scores of social communication, role-emotional, and mental health in all patients were lower (fig. 4). After one mo of treatment, the average score of these evaluation indexes gradually increased. After 3 mo of treatment, the average score of these evaluation indexes was 4 times higher than that before treatment, and the difference before and after treatment was significant (p<0.05). Lower limb VUL was considered as a public health problem, which has a significant social impact on the patients, their families, and the whole health system . The incidence of VUL was higher in the female and people over 61 y old, and most of these ulcers affect the social relations and work of the patients [10,11]. In this study, most of the participants were older than 61 y old and were female or retired, which was basically consistent with the previous studies. VUL mainly affects the female, which may be related to the pregnancy and female sex hormones [2,9]. Before treatment, the ulcer area of the patient was 16-20 cm2. However, after 3 mo of compression therapy, the skin lesions in 82 patients (91.11 %) were healed. In the treatment of VUL, the most important thing is to improve the venous reflux, which can be achieved by raising the affected limb and compression therapy .
The conventional therapy, improves vein circulation in your legs and treat swelling, by applying a firm compression bandage over the affected leg. These bandages are designed to squeeze your legs and encourage blood to flow upwards towards your heart. Compression therapy was the control measure of venous hypertension and the key to the effective treatment of VUL, which is often realized by stretch hose, elastic bandages or unna boots. The compression intensity of compression therapy gradually decreases from the ankle to knee to reverse the side effects of long standing posture and increase the hydrostatic pressure . After compression therapy on VUL patients, about 40 %-95 % of the cases can be completely cured, and the QoL and functional ability of the patients can be improved [14,15]. In recent decades, people pay more attention to QoL. QoL was originally used in other research areas, and later introduced into health, known as health-related quality of life (HRQoL), which can transform the subjective indicators into the quantitative indicators. The evaluation of QoL in patients with VUL was an important indicator of the evolution of wound healing. VUL causes changes in the patient’s limited mobility, unbearable pain, exudate and the stench of decay. These changes have negative effects on patient’s psychology, family relationship and social participation, and seriously affect patients QoL. In this study, the average SF-36 score of the patients before treatment was low, indicating a decrease in QoL. After 1 mo of compression therapy guided by unna boots, QoL was significantly improved. After 3 mo of treatment, almost all the patients had good QoL. In a study of 74 patients, the impact of lower limb VUL on patient’s lives was assessed, suggesting that the patients suffered from pain and drastic changes in QoL . Another study that assessed the effects of ulcers on patient’s daily lives found that the patients with ulcers showed pain, low self-esteem and social isolation. This may be related to that the patients were unable to participate in some daily activities harmoniously, thus reducing their selfesteem, self-image and QoL. However, it is worth noting that the results of this study found that the pain intensity of patients with ulcer healing decreased, the self-esteem and QoL also improved. The results showed that the compression therapy guided by Unna boots is effective in the treatment of lower limb VUL, which can not only improve the QoL of patients, but also help patients to restore self-confidence and self-esteem, and contribute to the recovery of patients.
