The control group was subjected to routine nursing. Specifically, the wound was cleaned and disinfected and the dressing was changed regularly according to the doctor's advice to ensure that the dressing was clean and dry until the wound healed.Patients in observation group were given whole course seamless nursing. A whole course seamless nursing group was set up, and a nursing plan was formulated according to the specific conditions of the patients. The specific measures were as follows:(1) Health education: After admission, health education was conducted for the patients. Pictures and videos were utilized to explain the causes, treatment methods and relevant precautions of chronic infectious wounds in detail for patients and their families. Then the patients' queries were listened to and answered. In the case of complication with diabetes, hypertension or other chronic basic diseases, the patients were guided to take hypoglycemic drugs or antihypertensive drugs according to the doctor's advice, so as to control blood glucose and blood pressure.2) Psychological nursing: The basic information of the patients was collected. The nursing staff communicated with the patients, and understood the patients' psychological dynamics by listening carefully to them. In addition, the nursing staff analysed the causes of negative emotions together with the patients, based on which they appeased and enlightened the patients, and illustrate cases where chronic infectious wound was successfully cured for the patients, so as to give the patients positive hints, and encouraged the patients to build up confidence.(3) Wound nursing: The patients' wound was cleaned, and a silicone drainage tube was placed at the wound as prescribed by the doctor. After the drainage tube was fixed with medical adhesive plaster, the wound was covered with a layer of aseptic biological semi-permeable membrane, which was fit to the silicone drainage tube, leaving no gap. Next, a small opening was trimmed on the aseptic biological semi-permeable membrane, and covered with a layer of aseptic Vaseline gauze. After the drainage tube was wrapped, the second layer of aseptic biological semi-permeable membrane and the second layer of aseptic Vaseline gauze were applied to form a closed negative pressure environment. Subsequently, the drainage tube was connected to a device of negative pressure suction. The negative pressure sealing materials were replaced every other week until the wound healed.(4) Discharge nursing: On the discharge day, the patients and their family members were informed of the cautions needing attention after discharge, and instructed the patients to regularly return to the hospital for re-examination. After discharge, the wound healing status of the patients were regularly followed up by telephone (once a week), and the patients were guided to have reasonable diet and maintain clean and ventilated home environment. In case of no granulation growth at the wound, it was necessary for the patients to return to the hospital for treatment.
