To quantify the exposure of very low birthweight neonates to ionising radiation from diagnostic x-rays.
Retrospective analysis was made of all radiographs performed over 18 months in an integrated special care baby unit and regional neonatal surgical unit in a large teaching hospital of surviving inborn babies of very low birthweight (< 1500 g) admitted to the unit.
Fifty five VLBW neonates were treated for a total of 3296 days and received 498 radiographs (median 5 per infant). The mean effective radiation dose was 0.04 mSv and the maximum for one infant was 0.54 mSv.
The radiation burden in this group of neonates is low and the benefits of diagnostic radiographs far outweigh any potential radiation risks.
量化极低出生体重新生儿接受诊断性X射线电离辐射的暴露情况。
对一家大型教学医院的综合特殊护理婴儿病房和区域新生儿外科病房在18个月内为该病房收治的存活的极低出生体重(<1500克)的足月儿所进行的所有X光片进行回顾性分析。
55名极低出生体重新生儿共接受了3296天的治疗,拍摄了498张X光片(每名婴儿中位数为5张)。平均有效辐射剂量为0.04毫希沃特,一名婴儿的最大剂量为0.54毫希沃特。
该组新生儿的辐射负担较低,诊断性X光片的益处远大于任何潜在的辐射风险。
