Summary A randomized double blind study of twice–weekly abdominal decompression from the 28th week of pregnancy, involving 411 primigravidae in three hospitals, is reported. No significant difference was noted in the admission rate for pre–eclampsia between 200 patients who were subjected to a suction pressure of 70 mm. Hg and 211 patients who were subjected to a suction pressure of only 20 mm. Hg. Although the length of hospital stay was significantly less in the former group, we conclude that routine antenatal decompression therapy plays no role in the prophylaxis of pre–eclampsia.

SummaryThe use of radioisotopes in localization of the placental site facilitates study of alterations in vascular haemodynamics under varying conditions. Measurements demonstrated that during pregnancy the application of abdominal decompression results in a 30 per cent increase in count rate over the placental site. There was a simultaneous fall in count rate over the head and lower limbs during the application of decompression. Severe exercise did not produce any change in count rate over the placental site. Measurements carried out during labour showed no change in count rate over the placental site during a uterine contraction, but a 10 per cent fall in count rate over the uterine wall away from the placental site. The application of abdominal decompression during a uterine contraction in the first stage of labour resulted in a 15 per cent increase in count rate over the placental site and over the uterine wall away from the placental site.
