Operating environment and usage of Wood's lamp
Although Wood's lamp is convenient and simple to use, it requires certain operating environment and skills in actual operation.
Darkroom: Wood's lamp must be operated in an absolute darkroom environment. It will not be possible to observe under natural light or in a darkroom with poor airtightness, or the observation effect and application value of Wood's lamp will be greatly lost or weakened.
Preparation before inspection: The Wood lamp should be preheated before use to ensure that the power of the Wood lamp source is stable and has sufficient energy to achieve satisfactory fluorescence imaging effects. The examiner also needs to stay in a dark room so that he can see the fluorescence emitted by the examined skin lesions clearly in a dark environment.
Inspection distance: Keep the distance between the Wood's lamp and the skin lesions to be observed until the skin lesions present a clear fluorescent image under the Wood's lamp. Too close to the center of the observation area of the Wood's lamp will produce dark spots, and the surrounding light will be too strong. If it is too far away, the light intensity of the observation area of the Wood's lamp will be insufficient, resulting in unclear fluorescence imaging.
Eliminate interfering factors: When performing Wood's lamp observation, try to avoid reflective or fluorescent objects around. Remove the clothing lint and fibers left on the skin of the examination area. Identify and eliminate the influence of external drugs, spices, dressings and other residues on fluorescence diagnosis. Interference and influence include blue or purple fluorescence produced by petroleum jelly ointment, green fluorescence produced by drugs containing salicylic acid, blue fluorescent reflection produced by the examiner's white coat, fluorescence of soap remaining on the patient's body surface, etc.
Note: Patients do not need to clean their skin locally before Wood's lamp examination to avoid affecting observation and judgment. When examining the face, patients should close their eyes and avoid looking directly at the light source.
