Comparative Study Clinical Trial Controlled Clinical TrialMenstrual blood loss in dysmenorrhoea: effects of proquazone and indomethacin.
Abnormal production of uterine prostaglandins (PG) causes primary dysmenorrhoea and excessive menstrual blood loss (MBL). We measured here MBL in primary dysmenorrhoea and found it to be normal during treatment with opiate analgesics (33.5 +/- 21.6 ml; mean +/- SD. n = 13), placebo (33.4 +/- 18.6 ml; n = 8), proquazone (31.8 +/- 18.0 ml; n = 8) and indomethacin (26.4 +/- 18.7 ml; n = 8). Proquazone and indomethacin relieved pain and other dysmenorrhoeic symptoms similarly in 33 women.

Comparative StudyEffect of lumbar epidural analgesia on lower urinary tract function in the immediate postpartum period.
Urodynamic investigations including cystometry and electronic simultaneous urethro-cystometry were made in 27 primiparae between 2 and 5 days after delivery to assess possible effects of lumbar epidural analgesia on the function of the lower urinary tract. Three groups of patients were studied: 11 patients had vaginal delivery without epidural analgesia, 11 patients with similar obstetrical characteristics were delivered vaginally with epidural analgesia, and five others were delivered by caesarean section under epidural analgesia. ⋯ The maximum cystometric capacity was significantly greater (P less than 0.05) in the group who delivered vaginally with epidural analgesia than in the group without epidural analgesia, as well as the caesarean section group (with epidural analgesia), (P less than 0.01). Possible side effects of epidural analgesia implied by these results are discussed and a method for surveillance of urethrovesical function both during labour and after parturition is proposed.

Selection of an obstetric data base for a microcomputer and its use for on-line production of birth notification forms, discharge summaries and perinatal audit.
A microcomputer system is described which stores data for perinatal audit and produces 'on-line' the statutory birth notification form and mother and baby discharge summary. The derivation of a minimum data-base and the methods used to obtain reliable data are outlined. ⋯ A study of the accuracy of the handwritten birth notification forms revealed a high error rate which was markedly reduced by the use of the microcomputer system. The system is now in routine use and further developments are outlined.
