We analysed retrospectively the link between the incidence of epidural analgesia and the frequency distribution of instrumental delivery, caesarean section, labour induction and parity in a selected group of women with a low risk labour profile in all (85) obstetric units in Flanders (Northern Belgium). A group of 104 932 women with presumed low risk labour profile was subjected to analysis. ⋯ The incidence of instrumental delivery in a given unit was greatly influenced by the rate of epidural analgesia and labour induction for convenience (P < 0.001). However, the incidence of caesarean section in a given unit was not determined by either the rates of epidural, labour induction, attempted instrumental delivery or the size of the unit.
