Abstract

The frequency and severity of retinal hemorrhages were studied in 200 newborns within the first 72 hours of life. One hundred of the neonates were delivered instrumentally by either forceps (49 cases) or vacuum extraction (51 cases). Another hundred neonates were delivered spontaneously and served as controls. Both the highest and the lowest frequency of retinal hemorrhages were found among the babies delivered by instrumentation. The actual values were 50 per cent in the vacuum groups and only 16 per cent in the forceps group (p less than 0.01). The spontaneously delivered babies, who served as controls, showed retinal hemorrhages in 41 per cent of the cases. The frequency of severe retinal hemorrhages was five times higher in the vacuum group compared to both the forceps group and the control group (p less than 0.01, p less than 0.001).

摘要

在200名新生儿出生后的头72小时内，对视网膜出血的频率和严重程度进行了研究。其中100名新生儿通过产钳（49例）或真空吸引（51例）助产。另外100名新生儿自然分娩，作为对照组。视网膜出血频率最高和最低的情况均出现在助产分娩的婴儿中。实际数值在真空吸引组为50%，而在产钳组仅为16%（p<0.01）。作为对照组的自然分娩婴儿中，41%出现了视网膜出血。与产钳组和对照组相比，真空吸引组严重视网膜出血的频率高出五倍（p<0.01，p<0.001）。
