摘要

黃疸燈光度與黃疸照光度療法的療效之間已經證實存在在著清楚的劑量－反應關係。此一研究的目的是希望要探討在不同類型的保溫箱之內與無保溫箱時所測得的光度是否有所差異。我們總共收集了四十四部保溫箱，分屬單層箱壁與雙層箱壁兩種機型，機齡最老的達十八年。與無保溫箱時測得的光度比較，在單層保溫箱內所測得的平均光度有意義地下降了，但是在雙層保溫箱內測得的平均光度卻輕微地增加。隨著箱壁受損嚴重程度的增加，保溫箱內測得的光度逐漸下降。在受損最爲嚴重的一組保溫箱內，光度減少了百分之十五。相對地，光度與保溫箱機齡之間並不具有相關性。總而言之，在保溫箱內測得的光度受到保溫箱類型與箱壁受損程度的影響。我們強調在實施照光治療之前在可保溫箱內測量光度的重要，尤其是那些箱壁嚴重受損的保溫箱。

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=0.0l4). 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.
