The incidence and severity of retinal haemorrhage were examined in 976 babies born by vaginal delivery. The influence of the method of analgesia, instrumental delivery and parity was studied. The mothers of 638 infants received extradural analgesia, while the other 338 received either narcotics or no analgesia. Extradural analgesia did not lead to a higher incidence of retinal haemorrhage, even though the number of vacuum extractions was doubled. With increasing parity, the total frequency and the frequency of severe retinal haemorrhage decreased (P less than 0.001). Severe retinal haemorrhage was not seen in any baby of whom the mother was para 4 or more.
对976例经阴道分娩的婴儿进行了视网膜出血的发生率和严重程度检查。研究了镇痛方法、器械助产和产次的影响。638名婴儿的母亲接受了硬膜外镇痛，而其他338名母亲接受了麻醉剂或未接受任何镇痛。硬膜外镇痛并未导致视网膜出血发生率升高，尽管真空吸引的次数增加了一倍。随着产次增加，视网膜出血的总发生率和严重视网膜出血的发生率降低（P<0.001）。母亲为经产妇4次及以上的婴儿中未发现严重视网膜出血。
