Summary The effects of continuous lumbar epidural analgesia on maternal arterial acid‐base balance and arterial lactate concentration in the second stage of labour were investigated. Although primiparae became more acidotic than multiparae, their rates of increase in acidosis were virtually identical. Epidural analgesia depressed the bearing‐down reflex and thus diminished the rate of production of lactate and the degree of maternal metabolic acidosis.
