目的 观察重度急性呼吸综合征(severe acute respiratory syndrome ,SARS)病房持续紫外线灯照射下,应用防晒霜对医护人员眼周暴露皮肤的防护效果。方法 将 49 例医护人员随机分为对照组与防护组,对照组暴露皮肤不应用防护用品,防护组在入病房前应用防晒指数(sun protection factor,SPF)为30的防晒霜。在第1周末及第3周末,分别观察暴露的局部皮肤有无损伤及其程度。结果 第1周时防护组出现皮肤损伤的阳性率及损害程度均低于对照组(P<0.05),第 3 周时防护组与对照组皮肤损伤阳性率差异不显著,但防护组皮损程度低于对照组(P>0.05)。结论 普通市售防晒霜可减轻紫外线照射引起的局部皮肤损伤程度,但长期应用不能阻止皮肤损伤的发生,急需研究适合 SARS病房医护人员工作环境的对短波紫外线有防护作用的防晒霜。
Objective To observe the protective effect of sunscreen on the exposed skin of medical staff under continuous ultraviolet light irradiation in patients with severe acute respiratory syndrome (SARS). Methods A total of 49 medical staffs were randomly divided into control group and protective group. In the control group, no protective equipment was applied to expose the skin. The protective group applied sunscreen with sun protection factor (SPF) of 30 before entering the ward. In the first weekend and the third weekend, were observed in the exposed local skin injury and its extent. Results At the first week, the positive rates of skin lesions and the degree of damage in the protective group were lower than those in the control group (P <0.05). There was no significant difference in the skin lesions between the protective group and the control group at the third week. However, Lower than the control group (P> 0.05). Conclusion Common sunscreens can reduce the degree of local skin damage caused by ultraviolet radiation. However, the long-term application can not prevent the skin damage. It is urgent to study sunscreens that are suitable for the work environment of SARS wards and have a protective effect against shortwave ultraviolet rays.
