Clinical efficacy of wet dressing combined with chitosan wound dressing in the treatment of deep second‐degree burn wounds: A prospective,randomised, single‐blind,positive control clinical trial

To evaluate the efficacy and safety of wet dressing combined with chitosan wound dressing for deep II degree burn wounds, and provide the basis for clinical application. From October 2019 to October 2021, 80 patients with second‐degree deep burn treated in the Department of burn and plastic surgery of our hospital were selected as the research objects. Patients were randomly divided into two groups. The control group (40n) was treated with wet compress, and the study group (40n) was treated with wet compress combined with chitosan wound dressing. The wound healing time, wound healing percentage and pain score were used as the effectiveness indexes, and the incidence of adverse events and serious adverse events and the detection rate of bacterial culture of wound exudates were used as the safety indexes. The efficacy and safety of the two groups were compared. The wound healing time of the study group (19.53 ± 2.74 days) was shorter than that of the control group (24.78 ± 4.86 days), the difference was significant (t = 3.571, P = 0.015). The percentage of wound healing at the 14th after treatment in the study group was higher than that in the control group (65.00% versus 37.50%) (X² = 6.054, P = 0.014). There was no significant difference in pain scores between the two groups at each time point. The scar growth was observed 3 months after wound healing. The scar score of the study group (6.00 ± 0.98) was lower than that of the control group (8.77 ± 1.19) (t = 2.571, P = 0.031). The positive rate of wound secretion culture on the 7th and 14th day was statistically significant (X² = 4.528, P = 0.033; X² = 6.646, P = 0.010), and the study group was lower than the control group (29.03% versus 81.82%; 8.11% versus 42.86%). There was no significant difference in treatment cost between the study group and the control group (1258.7 ± 223.6 versus 1248.9 ± 182.3) (t = 1.571, P = 0.071). No adverse events or serious adverse events occurred in both groups. Chitosan wound dressing can significantly shorten the time of wound healing and reduce wound pain and wound infection in patients with deep second‐degree burns. And it can effectively improve the situation of scar hyperplasia, which is worthy of clinical application.

Recombinant human granulocyte-macrophage colony-stimulating factor hydrogel promotes healing of deep partial thickness burn wounds

Objective

To assess the effects of recombinant human granulocyte/macrophage colony-stimulating factor (rhGM-CSF) hydrogel on the healing of deep partial thickness burn wounds.

Methods

Ninety three wounds of 65 burn patients who suffered from a deep partial thickness burn of <5% TBSA and could not heal over 3 weeks were included in this study. The patients were randomly assigned to use rhGM-CSF hydrogel (GC group, n = 32) or hydrogel without rhGM-CSF (control group, n = 33). rhGM-CSF hydrogel or hydrogel without rhGM-CSF was topically applied to the wounds, the dressing was changed once a day. Wound healing time and percentage, wound discharge, periwound inflammation, the positive wound swabs culture count, and adverse drug reactions were observed and compared between two groups.

Results

Healing time was 12.2 ± 5.0 days after the application of rhGM-CSF hydrogel. This was significantly shorter than that of control wounds (15.5 ± 4.7 days). Healing percentage at 14 days in the rhGM-CSF-treated wounds was 97.5 ± 7.7%, which was markedly higher than the control (85.9 ± 6.8%). At 3, 6, 12, 14 day, the GC group was significantly superior to the control group with respect to the score of periwound inflammation, wound purulence and discharge. The positive wound swabs culture count of the GC group on the 7th and 14th day post-treatment was 14 and 4, respectively, which was significantly lower than the control.

Conclusion

rhGM-CSF hydrogel promotes the healing process of deep partial thickness burns effectively. No adverse reaction of the drug was observed during the study.     

A comparative study to evaluate the effect of honey dressing and silver sulfadiazene dressing on wound healing in burn patients

To compare the effect of honey dressing and silver-sulfadiazene (SSD) dressing on wound healing in burn patients. Patients (n=78) of both sexes, with age group between 10 and 50 years and with first and second degree of burn of less than 50% of TBSA (Total body surface area) were included in the study, over a period of 2 years (2006-08). After stabilization, patients were randomly attributed into two groups: ‘honey group’ and ‘SSD group’. Time elapsed since burn was recorded. After washing with normal saline, undiluted pure honey was applied over the wounds of patients in the honey group (n=37) and SSD cream over the wounds of patients in SSD group (n=41), everyday. Wound was dressed with sterile gauze, cotton pads and bandaged. Status of the wound was assessed every third and seventh day and on the day of completion of study. Patients were followed up every fortnight till epithelialization. The bacteriological examination of the wound was done every seventh day. The mean age for case (honey group) and control (SSD group) was 34.5 years and 28.5 years, respectively. Wound swab culture was positive in 29 out of 36 patients who came within 8 hours of burn and in all patients who came after 24 hours. The average duration of healing in patients treated with honey and SSD dressing at any time of admission was 18.16 and 32.68 days, respectively. Wound of all those patients (100%) who reported within 1 hour became sterile with honey dressing in less than 7 days while none with SSD. All of the wounds became sterile in less than 21 days with honey, while tthis was so in only 36.5% with SSD treated wounds. The honey group included 33 patients reported within 24 hour of injury, and 26 out of them had complete outcome at 2 months of follow-up, while numbers for the SSD group were 32 and 12. Complete outcome for any admission point of time after 2 months was noted in 81% and 37% of patients in the honey group and the SSD group. Honey dressing improves wound healing, makes the wound sterile in lesser time, has a better outcome in terms of prevention of hypertrophic scarring and post-burn contractures, and decreases the need of debridement irrespective of time of admission, when compared to SSD dressing.
