Journal Article
To determine whether fetal breathing movements (FBM) in pregnancies with oligohydramnios change with restoration of amniotic fluid volume.
A prospective experimental study.
Fetal Medicine Unit, ...tertiary referral hospital.
16 women with singleton pregnancies complicated by severe oligohydramnios.
Restoration of amniotic fluid volume by transabdominal amnioinfusion. Controls comprised pregnancies in which infused fluid leaked vaginally, so that oligohydramnios was not corrected.
Change in total breathing movements, change in FBM incidence derived from 40 min recordings immediately before and after amnioinfusion.
There was no significant difference in the change in total breathing movements or in the change in incidence of FBM between the 10 pregnancies in which amniotic fluid volume was restored, and the other six in which fluid leaked after infusion and volume was not restored. In both groups, there was no significant change with infusion in number of FBM (mean change -72, 95% CI -218 to +74 in the fluid-retained group and -64, 95% CI -273 to +145 in the fluid-leaked group) and incidence of FBM (median change -2.5%, range -27 to +10 in the fluid retained group and -4.5%, range -34 to +15 in the fluid-leaked group).
This study suggests that restitution of amniotic fluid volume in human pregnancies complicated by severe oligohydramnios does not acutely alter the incidence of FBM. These data support an increasing literature suggesting that impairment of fetal breathing is not the mechanism for oligohydramnios-related pulmonary hypoplasia.
Data from 99 intra-uterine transfusions performed in 30 patients (31 fetuses) with Rh allo-immunization have been reviewed. Mean gestational age at the first transfusion was 23.6 weeks and mean fetal ...haematocrit 19.8%. The number of procedures was on average 3.2 per fetus. Survival rate was 84%. Fifty-nine intravascular transfusions were combined with intraperitoneal transfusions. Combined intravascular and intraperitoneal transfusions, when compared to intravascular transfusions alone, achieved a significantly longer interval between transfusions and also maintained a higher fetal haematocrit at the subsequent transfusion. Mean fall in fetal haematocrit was 0.98% per day with a wide range. There was a general tendency towards a less marked fall during the second interval between transfusions than in the first with the exception of those cases in which the percentage of fetal red cells at the start of the second transfusion was increased compared to that which was found at the end of the first, i.e., when fetal erythropoiesis was not suppressed.
To establish a technique for continuous recording of fetal electrocardiograms (ECG) for waveform analysis in the antenatal period.
Prospective descriptive study.
Fetal Medicine Unit, Queen ...Charlotte's and Chelsea Hospital, London, UK.
35 women undergoing antenatal fetal blood sampling.
One end of an insulated Cooner wire was attached to the sampling needle and the other to an automatic ECG-ST waveform analyser.
ECG signals were obtained with the needle in the fetal abdomen during intrahepatic umbilical vein sampling or aspiration of fetal urine but not when it was in the placental cord insertion.
Continuous recording of the T/QRS ratio was obtained for a total of 166 min (mean 8 min per fetus) from 20 fetuses (16-38 weeks). The T/QRS ratio had no correlation with gestational age and fetal heart rate and was similar to values described in term fetuses in labour.
The technique described can identify ST waveform changes and may be useful in the investigation of fetal cardiac arrhythmias, intrauterine growth retardation and in monitoring fetal transfusions.
