A clear dose-response relationship has been demonstrated between the irradiance and the effectiveness of phototherapy. This study is designed to detect if there is any difference in irradiance between the inside and outside of different types of incubators. Forty-four incubators of two different types and with ages up to 18 years were included. In comparison with the measurement taken outside an incubator, the mean spectral irradiance detected within a single-walled incubator was significantly decreased (p < 0.001) while that detected within a double-walled incubator was slightly increased (p = 0.014). The reduction of spectral irradiance within an incubator correlated with the degree of incubator wall damage with a maximal loss of 15%. However, the irradiance did not correlate with the age of the incubator. In conclusion, the spectral irradiance received within an incubator was influenced by the type of incubator and the wall damage. Measuring the irradiance within an incubator prior to phototherapy should be emphasized, especially for those incubators with severely damaged walls.
光疗的辐照度与疗效之间已证实存在明确的剂量反应关系。本研究旨在检测不同类型暖箱内部和外部的辐照度是否存在差异。纳入了44台两种不同类型、使用年限达18年的暖箱。与暖箱外部的测量结果相比，单壁暖箱内检测到的平均光谱辐照度显著降低（p < 0.001），而双壁暖箱内检测到的则略有升高（p = 0.014）。暖箱内光谱辐照度的降低与暖箱壁损坏程度相关，最大损失为15%。然而，辐照度与暖箱的使用年限无关。总之，暖箱内接收到的光谱辐照度受暖箱类型和壁损坏情况的影响。应强调在光疗前测量暖箱内的辐照度，尤其是对于壁严重损坏的暖箱。
