title: Enflurane as an analgesic in labour.
abstract: A comparison of the analgesic efficacy of enflurane 1% in air with Entonox (50% nitrous oxide in oxygen) was performed in 20 consenting women during the first stage of labour. The two drugs were given in a random sequence to each woman, who also acted as her own control. Pain scores were significantly lower with enflurane than Entonox, although drowsiness scores were higher. No untoward effects were reported with either agent. The use of enflurane as an analgesic in the first stage of labour warrants further investigation.
