Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medicine, and in particular to an ointment for treating burns and scalds and chronic refractory wounds and a preparation method thereof. Background Art
[0002] Burns and scalds and chronic intractable wounds are common accidental injuries in life, mainly caused by flames, boiling water, hot steam, chemicals, light, electricity, radiation, traumatic infection, local tissue pressure of bedridden patients causing pressure sores, diabetic foot ulcers, vascular diseases causing lower limb ulcers, etc. Burns and scalds can cause skin tissue damage, redness, swelling and pain, blisters, and even skin peeling. In severe cases, the wounds will ulcerate and damage tissues and bones. For some severe burns and scalds or chronic intractable wounds, if not treated in time, it will lead to adverse consequences, such as sepsis caused by bacterial infection, or even death. So far, burns and scalds and chronic intractable wounds still have problems such as wound pain, progressive necrosis, easy infection, difficulty in healing, and scars. Western medicine surgery, such as skin grafting, is currently one of the main methods for treating severe deep burns and chronic refractory wounds. However, the use of skin grafting and other surgical operations for treatment is expensive and has many complications. After the major wounds are necrotic, the real skin cannot be regenerated and scars are left, which makes the patient prone to adverse reactions, and even serious damage to the function of important organs or systems, resulting in disability or death. Western medicine topical drugs, mainly antibacterial topical drugs, such as silver sulfadiazine, are currently one of the methods for treating mild burns and scalds, but have the disadvantage of aggravating wound damage. Correspondingly, my country's traditional Chinese medicine has rich experience in the treatment of burns and scalds, mainly topical drugs, such as lithospermum oil, Jingwanhong ointment, compound aloe cream, compound bear bile liquid, burn spirit, etc. Although these products have a certain degree of antipruritic, anti-inflammatory, analgesic, and wound healing effects on burns and scalds, they are easy to leave scars and the healing effect is not ideal.

[0046] Typical cases:
[0047] Hu X, male, 52 years old, from Binyang County, Guangxi, was burned in June 2019, covering about 50% of his body area, with second-degree burns. The wound was cleaned with normal saline, and the ointment for treating burns and scalds of the present invention was applied to the wound with a sterilized cotton swab and bandaged with gauze. The dressing was changed once a day, and the condition improved significantly after 10 days.
[0048] Lin XX, male, 6 years old, from Binzhou Town, Binyang, Guangxi. In July 2023, he accidentally fell into a bucket full of boiling water, causing burns on his back, buttocks, and thighs, covering an area of about 55%. Second degree deep. The epidermis peeled off, with a red and white base. After admission, the wound was cleaned with saline, and the ointment for treating burns and scalds of the present invention was applied to the wound with a sterilized cotton swab and bandaged with gauze. The dressing was changed once a day, and the wound was completely healed in 14 days without leaving obvious scars.
[0049] Zhang XX, 24 years old, from Longxiang, Shanglin Town, Guangxi, was burned by flames in January 2022, with an area of about 60%, of which the superficial second degree accounted for 22%, the deep second degree accounted for 32%, and the third degree accounted for 6%. The epidermis was completely peeled off, the base was red and white, and the forearms were leathery, with hypovolemic shock. While giving fluid infusion to resist shock and infection, the wound was cleaned with normal saline, and the ointment for treating burns and scalds of the present invention was applied to the wound with a sterile cotton swab and bandaged with gauze. The dressing was changed once a day and the patient was discharged from the hospital after 21 days of recovery.
[0050] Test Example 1
[0051] A total of 60 patients with second-degree burns admitted to our hospital from February 2023 to May 2024 were divided into two groups, 30 cases in each group. In the observation group, there were 20 males and 10 females; the admission time was 1-10h after burn, with an average of (3.4±0.7)h; the age was 7-60 years old, with an average age of (39.5±4.9) years old; the burn area: >30% in 13 cases, ≤30% in 17 cases. In the control group, there were 21 males and 9 females; the admission time was 1.5-10h after burn, with an average of (3.7±0.8)h; the age was 5-60 years old, with an average age of (38.9±4.2) years old; the burn area: >30% in 15 cases, ≤30% in 15 cases.
[0052] Inclusion criteria:
[0053] ① The patient's medical history and clinical observations meet the criteria for second-degree burns; ② The patient is between 3 and 60 years old; ③ No hormones or other drugs that affect metabolism have been used in the past month; ④ Agree to accept clinical observation and can cooperate closely during the observation; ⑤ The informed consent form is signed by the patient or his / her guardian.
[0054] Exclusion criteria:
[0055] ① With cardiovascular system lesions; ② With failure of important organ functions; ③ With mental illness or cognitive impairment; ④ With allergic reaction to the drugs used in this study; ⑤ With systemic infection.
[0056] After admission, both groups were treated with debridement, and the wound surface and its surrounding pollutants, necrotic and detached epidermis were removed cleanly. The debridement operation needs to be performed carefully and gently, and the wound surface should be thoroughly cleaned, and the residual active tissue of the wound surface should be retained, and then the wound surface should be cleaned and disinfected after removal, and then the residual moisture of the wound surface is blotted dry. After the wound surface is treated cleanly, the control group uses nano silver burn and scald dressing (Anxin Biotechnology Co., Ltd., product standard number: YZB / Guo 57442014) to bandage, take nano silver burn and scald dressing to cover the wound surface, then bandage with sterile dry gauze, and fix it after bandaging, 1 time / d. The observation group uses the ointment for the treatment of burns and scalds obtained by Example 5 of the present invention, 1 time / d. Both groups were treated continuously for 3 weeks, and nutritional intervention was strengthened during treatment, and patients were advised to rest more to avoid wound pressure, and anti-infection intervention could be given according to the actual situation of the patient.
[0057] Observation indicators: Comparison of treatment effect, wound healing time, bacterial culture results of wound secretions and adverse reactions between the two groups. (1) Treatment effect judgment criteria: Wound healing>78%, pus accumulation under the scab, and no inflammatory symptoms on the wound are considered cured; wound healing 56%-78%, no purulent material, and no inflammatory symptoms on the wound are considered markedly effective; wound healing 25%-55%, less purulent material, shallow scars and pigment changes, and milder inflammatory symptoms are considered effective; wound healing <25%, no reduction in purulent secretions, severe scars, pigment changes and inflammation are considered ineffective. Cure + markedly effective + effective = total effectiveness. (2) Wound healing time and hospitalization time of the two groups were recorded and compared between the two groups. (3) The positive rate of bacterial culture of wound secretions was compared between the two groups before treatment, 1 week after treatment, and 3 weeks after treatment, and wound secretions were taken for bacterial culture. (4) Adverse reactions: redness, swelling, fever, and itching.
[0058] The results are shown in Table 1.
