The incidence and magnitude of retinal haemorrhages in a group of neonates delivered spontaneously (n = 50), whose mothers received epidural analgesia during labour, has been compared to those of a spontaneously delivered control group (n = 50) who received conventional analgesia. The second stage of labour was significantly longer in the epidural group (P less than 0.001), which contained a higher number of primiparas than did their controls. Still, a lower incidence of retinal haemorrhages was noted in the epidural group (P less than 0.01). The study indicates that epidural analgesia offers a certain degree of protection against perinatal retinal haemorrhages in the spontaneously delivered neonate.
一组自然分娩（n = 50）且母亲在分娩期间接受硬膜外镇痛的新生儿视网膜出血的发生率和严重程度，已与另一组接受传统镇痛的自然分娩对照组（n = 50）进行了比较。硬膜外组的第二产程明显更长（P < 0.001），且初产妇数量高于对照组。尽管如此，硬膜外组的视网膜出血发生率较低（P < 0.01）。该研究表明，硬膜外镇痛对自然分娩新生儿的围产期视网膜出血提供了一定程度的保护。
