Evaluation of fetal monitoring by telemetry.

A radiotelemetry system for the direct monitoring of fetal heart rate and intrauterine pressure during labor has been evaluated at 5 different institutions. A conventional fetal scalp electrode and a special intrauterine pressure sensor are connected to a radio transmitter placed on the patient's thigh. The receiver can be located up to 50 feet away from the transmitter and is either a self-contained monitor or a unit that converts a conventional fetal monitor to a telemetric one. The telemetry recordings are of similar quality to those obtained from conventional monitors. Telemetry allows for greater patient comfort and mobility as well as greater convenience to the clinical staff. Continuous data can be obtained from patients while they are ambulatory or sitting in a chair as well as while they are in bed.

Sinusoidal fetal heart rate pattern associated with alphaprodine administration.

Sinusoidal fetal heart rate patterns were observed in 42.5% of a group of 40 women who had received alphaprodine (Nisentil) for relief of labor pain. Analysis showed that the pattern appeared approximately 19 minutes following alphaprodine administration and persisted for approximately 60 minutes. In a control group of 18 patients who did not receive narcotic analgesia, and intermittent sinusoidal pattern was observed in one patient. All babies with sinusoidal heart rate during labor had 1-minute Apgar scores of 7 or greater except two in the study group. Both these neonates had low Apgar scores directly associated with complications at delivery. All 5-minute Apgar scores were 7 or greater, and there were no perinatal deaths.

Fetal bradycardia without fetal distress: case presentation and review of the literature.

A case of a term pregnancy with a persistent fetal heart rate of 65 to 80 beats/min is presented. Initially this was presumed to be due to congenital heart block. Subsequent fetal ECG revealed blocked atrial extrasystoles. Review of the literature showed 31 previously reported cases of heart block diagnosed in utero. A review of this literature is discussed and the importance of differentiating bradycardia due to heart block from bradycardia due to fetal distress is emphasized.

Practical prenatal care. I. Initial prenatal care.

Most factors which place the mother or fetus at risk are present at the time of the initial prenatal visit or develop during the pregnancy and before admission to the hospital. As many as 40 per cent of all high risk patients may be detected at the initial prenatal visit.

Five years' experience with intrauterine transfusion.

Five years' experience with intrauterine transfusion involving 94 transfusions on 50 fetuses forms the basis of the paper. Twenty-three fetuses survived, which represents an overall salvage of 46%. Of 22 fetuses who received intrauterine transfusions before 28 weeks' gestation, seven (31.9%) survived, which justifies the attempt. Of 28 fetuses who received intrauterine transfusions after 28 weeks' gestation, 16 (57.1%) survived, which compares favourably with other series. A comparison of two different procedural techniques shows no statistically significant difference in ultimate results. Indications for amniocentesis are outlined and intrauterine transfusion was advised if the optical density difference fell in Liley's zone III (or a very high zone II) and rose at a rate which anticipated a zone III reading prior to 32 weeks' gestation. A pediatric assessment and therapeutic management of the 33 live births are presented. Twenty-eight babies received exchange transfusions. Five were excluded for reasons outlined in the text. Ten of the live-born died neonatally. The 23 survivors continue to thrive mentally and physically and follow-up continues.
