Summary The effectiveness in clinical practice of conventional analgesia, with pethidine and 50 per cent nitrous oxide in oxygen (Entonox) has been studied in 663 consecutive patients. More than 75 per cent of mothers stated that they had obtained little or no pain relief from pethidine in the manner in which it was administered. In comparison, nearly half the patients who received Entonox had satisfactory analgesia and the incidence of acceptable pain relief with both agents was unrelated to parity. The number of patients receiving satisfactory analgesia was disturbingly low.
