Abstract: Objective · To evaluate shaped polyurethane foam dressing applied on scalp donor sites in the patients with extensive burn. Methods · The extensively burned adult patients without chronic diseases before injury, who were hospitalized in the Department of Burns and Plastic Surgery, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine October, 2017 to October, 2018 were selected. Their scalps as skin donor sites during all past grafting surgeries were divided into two groupsdifferent treatments, i.e. control group and research group. The scalps in control group were coveredgauze clippedthe skulls. Those in research group were coveredshaped polyurethane foam dressing. Afterwards, the wound healing time for the scalps, the intervals between the two adjacent grafting operations, the post-operation pain assessedvisual analogue scale (VAS), and the workload of medical staffs were analyzed and compared between the two groups. Results · The mean time of wound healing for scalp donor sites in research group was (6.77±0.10) d, whereas it was (9.73±0.17) d in control group. For the intervals between the two contiguous operations, they were (9.33±0.16) d in research group and (11.90±0.22) d in control group, respectively. The differences in these two indexes between the two groups were statistically significant (P0.000). Also, the VAS scores were significantly lower in research group compared with those in control group at all the points after operations (P0.000). The application of shaped polyurethane foam dressing evidently reduced the treatment time for turning bed and had no need of lamp-aid treatment, so it reduced the workload for medical staffs. Conclusion · The application of shaped polyurethane foam dressing on extensively burned patients’ scalp may significantly accelerate its wound healing, shorten the intervals between two grafting operations, which will be beneficial in closing the wounds of these patients earlier eventually. Meanwhile, its application may also alleviate pains of the patients and reduce the burdens of post-operation nursing.
