目的 探讨季铵盐壳聚糖新型液体敷料对面部裂伤促愈合及抑制瘢痕形成的影响。 方法 2022年5月至2023年2月，四川省人民医院整形外科颜面部皮肤软组织裂伤患者113例，男52例、女61例；年龄18～30(25.8±5.2)岁。分为两组，试验组62例在缝合中用季铵盐壳聚糖冲洗伤口，并在换药时于创面喷洒季铵盐壳聚糖新型液体敷料；对照组51例，缝合与换药过程中的季铵盐壳聚糖新型液体敷料替换为等量的生理盐水，其余过程同试验组。术后30、60、90 d进行随访。术前、术后即刻、换药前后、随访时均进行拍照，记录并评估患者面部裂伤疼痛评分、愈合等级、瘢痕评分及患者满意度。 结果 患者113例无失访。术后换药过程中，数字评分法(numerical rating scale, NRS)：试验组患者1 d NRS (1.03±0.18)分、3 d NRS (2.69±0.53)分、5 d NRS (0.53±0.50)分均低于对照组患者1 d NRS (2.35±0.59)分、3 d NRS (3.27±0.75)分、5 d NRS (0.80±0.40)分(均P<0.05)。甲级愈合率：试验组患者58例(93.5%)高于对照组40例(78.4%)(χ2＝5.56，P<0.05)。温哥华瘢痕评分量表总分：试验组患者30 d (1.65±0.48)分、60 d (3.97±1.11)分、90 d (2.90±0.76)分均低于对照组30 d (2.43±0.50)分、60 d (5.16±1.21)分、90 d (3.55±0.78)分(均P<0.05)。患者满意度：试验组58例(93.6%)高于对照组42例(82.3%)(χ2＝8.16，P<0.05)。 结论 季铵盐壳聚糖新型液体敷料可减轻伤口疼痛、促进创口愈合、减轻瘢痕形成、提高患者满意度。 Objective To investigate the effect of a novel liquid dressing of quaternary chitosan on facial laceration healing and inhibition of scar formation. Methods This study was a prospective study, including 113 cases of facial skin soft tissue laceration 52 males, 61 females, age range of 18-30 years, with mean (25.8±5.2) years in the Department of Plastic and Reconstructive Surgery, Sichuan Provincial People′s Hospital from May 2022 to February 2023. Patients were divided into two groups: the experimental group (62 cases) used quaternary ammonium chitosan rinsing wounds in the suture, and trauma spray quaternary ammonium chitosan liquid dressing in the dressing change saline instead of an equal amount of chitosan was used to rinse wounds during the suture process and routine dressing change in the control group (51 cases). Follow-up visits were carried out in 30 d, 60 d, and 90 d postoperatively, and standardized photographs were taken preoperatively in the immediate postoperative period, before and after dressing change. The healing of the patients′ facial lacerations and patient satisfaction were recorded and assessed at the follow-up visits. Results A total of 113 patients were included in this study, with no lost visits. During postoperative dressing change, 1 d NRS (1.03±0.18), 3 d NRS (2.69±0.53), and 5 d NRS (0.53±0.50) were lower in the experimental group than those in the control group [1 d NRS (2.35±0.59), 3 d NRS (3.27±0.75), and 5 d NRS (0.80±0.40) (all P<0.05)]. Grade A healing rate was 93.5% (58 patients) in the test group were higher than 78.4% (40 patients) in the control group (χ2= 5.56, P<0.05) the total scores of the Vancouver Scar Rating Scale in the experimental group were lower than those of the control group at 30 d (1.65±0.48), 60 d (3.97±1.11), and 90 d (2.90±0.76) vs. 30 d (2.43 ±0.50), 60 d (5.16±1.21), and 90 d (3.55±0.78) (t=8.48, 5.44, t=4.43 P<0.05) the overall satisfaction rate in the experimental group (93.6%) was higher than that of the control group (82.3%) (χ2=8.16, P<0.05). Conclusions Quaternary chitosan liquid dressing has obvious advantages in reducing wound pain, promoting wound healing, and reducing scar formation. It can improve patients′ satisfaction and worthwhile to be applied clinically.
