透過超音波測量評估手臂燒傷患者燒傷疤痕的厚度
Assessing thickness of burn scars through ultrasound measurement for patients with arm burns
摘要
介紹：燒傷傷口癒合期間，疤痕會堵塞毛細血管。穿著壓力衣（Pressure Garment :PG）會抑制氧氣流向組織，從而加速疤痕成熟並減少疤痕厚度。在這項研究中，超音波測量被用於揭示男性和女性患者手臂燒傷疤痕厚度的客觀差異。 方法：由經驗豐富的醫生使用超音波儀器和數位身高體重電子儀器來測量正常的皮膚和疤痕厚度以及患者的體重指數（BMI）。 在測試當天，患者當日手臂上的壓力衣（PG）將會移除。 結果：對於女性和男性燒傷傷友，所測量的疤痕厚度分別與正常皮膚厚度是3.82倍和2.28倍。因此，使用24 mmHg PG的男性和女性患者的疤痕厚度不同。女性患者的疤痕組織比男性患者的疤痕組織厚。我們還觀察到BMI較高（22.4–23.8）的患者平均疤痕厚度較低。 討論：這項研究建議參與者的年齡範圍不超過10歲，因為皮膚厚度受多個因素的影響，包括年齡，性別和BMI。年齡差距越小，找到適合所有年齡組的最佳解決方案的可能性就越高。 結論：我們的研究結果表明，BMI（體重指數）較高的患者的疤痕平均厚度較低。儘管這些發現是值得注意的，但對不同的身體類型和身體部位施加了相同的壓力。疤痕的高度在患者身體各個部位也不同。我們希望招募更多身體其他部位有燒傷的患者，以擴展我們的發現。

Introduction: During burn wound healing, scarring occludes the capillaries. Wearing pressure garments (PGs) inhibits the flow of oxygen to the tissue, which accelerates scar maturation and reduces scar thickness. In this study, ultrasound measurement was used to reveal objective differences between male and female patients in arm burn scar thickness. Methods: An experienced physician trained by radiologists used an ultrasound machine and a digital height and weight scale to measure normal skin and scar thicknesses and patients’ body mass indices (BMIs). On the day of testing, the pressure garments (PGs) on the patients’ arms were removed. Results: The scars measured were 3.82 and 2.28 times thicker than the unaffected skin for female and male patients, respectively. The scars measured for female patients were, on average, 1.67 times thicker than those measured for male patients. The test for equal variances for both groups resulted in no overlapping intervals and significantly different corresponding standard deviations. Thus, scar thicknesses differed between male and female patients using 24-mmHg PGs. The scar tissue of female patients was thicker than that of male patients. We also observed that patients with a high BMI (22.4-23.8) had smaller mean scar thicknesses. Discussion: This research recommends an age range of participants that does not exceed 10 years because skin thickness is affected by several factors, including age, sex, and BMI. The narrower the age range is, the higher is the likelihood of finding the best solution for all age groups. Conclusion: Patients with a high BMI had smaller mean scar thickness Although these findings are notable, the same pressure was applied to different body types and body parts; the height of the scars also varied across different areas of patients’ bodies. We hope to recruit more patients with burns on other parts of the body to extend our findings.
