Phototherapy remains an important component of the management of unconjugated neonatal jaundice, a major cause of newborn morbidity. During phototherapy the toxic unconjugated form of bilirubin is converted to nontoxic form through action of light delivered by phototherapy. An important possible complication of phototherapy is retinal damage and therefore eye protective measures are taken during therapy to prevent this from occurring. Devices currently in use for phototherapy are capable of providing intensive phototherapy with the attendant increased risk of eye injury. The materials used in providing eye protection are varied among care providers. A dearth of information exists on shielding provided by the commonly used eye protectors during phototherapy, more so during intensive phototherapy.
To evaluate the shielding provided by the different eye protectors commonly used in our setting under intensive phototherapy.
Five materials in use for eye shielding were obtained. Using an institutional built light emitting diode phototherapy device, intensive phototherapy was provided and the irradiance at varying distances of 35 cm, 25 cm, 15 cm and 10 cm was measured using an Olympic bili meterTM Natus. At the distance of each measured irradiance the different eye protective materials were then placed one after the other over the surface of the measuring sensor of the meter and the irradiance measurement was recorded. Two measurements were taken for each material at each distance and the average irradiance measurement was then recorded for each of the materials tested at that distance.
Five eye shielding materials in use were identified: black cotton fabric, white cotton fabric, black cotton fabric with foam, white cotton fabric with foam and gauze. The black cotton fabric with or without foam at the phototherapy device irradiances of 30, 46.3, 58.7 and 75.4 µw/m2/nm recorded 0 irradiance.
Black cotton fabric with or without foam pad provided the most shielding under intensive phototherapy.
光疗仍然是治疗未结合型新生儿黄疸的重要组成部分,未结合型新生儿黄疸是新生儿发病的主要原因。在光疗过程中,胆红素的有毒非结合形式通过光疗提供的光的作用转化为无毒形式。光疗的一个重要潜在并发症是视网膜损伤,因此在治疗过程中采取眼部保护措施以防止发生这种情况。目前用于光疗的设备能够提供高强度光疗,随之而来的眼部损伤风险增加。在提供眼部保护方面,护理提供者使用的材料各不相同。在光疗期间,尤其是在高强度光疗期间,常用眼部保护器提供的屏蔽信息很少。
评估在高强度光疗下,我们环境中常用的不同眼部保护器提供的屏蔽效果。
获得了五种用于眼部屏蔽的材料。使用机构内部的发光二极管光疗设备,提供高强度光疗,并使用 Olympic bili meterTM Natus 测量 35cm、25cm、15cm 和 10cm 不同距离的辐照度。在测量辐照度的每个距离处,将不同的眼部保护材料依次放置在光度计测量传感器的表面上,然后记录辐照度测量值。每种材料在每个距离处进行两次测量,然后记录测试材料在该距离处的平均辐照度测量值。
确定了五种在使用的眼部屏蔽材料:黑色棉织物、白色棉织物、带有泡沫的黑色棉织物、带有泡沫的白色棉织物和纱布。在光疗设备辐照度为 30、46.3、58.7 和 75.4µw/m2/nm 时,带有或不带有泡沫的黑色棉织物记录为 0 辐照度。
带有或不带有泡沫垫的黑色棉织物在高强度光疗下提供了最大的屏蔽效果。
