摘要:

Randomized clinical trials have not provided unequivocal justification for the routine use of ultrasound in antenatal management. Nonetheless, routine ultrásonography is widely practiced in many places, there is no evidence to suggest it is biologically harmful, and its diagnostic capabilities are being increasingly documented. There are, however, no studies of the clinical, psychological or economic benefits of routine ultrasound in clinically low-risk patients who would not normally be scanned. To avoid continuing uncertainty about the risks and benefits of routine ultrasound, randomized trials should be conducted of future developments in technique and procedure in places where routine scanning is common. In places which have not adopted routine scanning randomized trials could still answer fundamental questions about routine use of the technique

摘要:

Real-time directed M-mode echocardiography permits analysis of atrial and ventricular mechanical systole and allows inference of the type of arrhythmia present. Accurate diagnosis in cases of fetal tachyarrhythmia is of vital importance when therapy is considered, and in planning further management and delivery of an affected infant. Fetal tachyarrhythmia may be life-threatening especially when fetal hydrops is present and aggressive therapy is mandatory in these cases with digoxin being the drug of choice. In our series the incidence (8.3%) of congenital heart disease was as expected, but the incidence (54%) of atrial flutter was surprisingly high. The prognosis was dependent on the presence or absence of fetal hydrops and was not influenced by the type of arrhythmia or gestational age.

摘要:

We investigated simultaneously blood flow velocity waveforms of uteroplacental vessels, the umbilical artery, the fetal aorta and the fetal common carotid artery. In pregnancies with intrauterine growth retardation or preeclampsia we found low diastolic velocities in uteroplacental vessels, the umbilical artery and the fetal aorta and high diastolic velocities in the common carotid artery. Abnormal waveforms of the common carotid artery were most effective in predicting fetal compromise and might be a valuable clinical tool for the supervision and therapy of high-risk pregnancies in the future.

摘要:

A case of intrauterine growth retardation with marked oligohydramnios is presented in which, following amnioinfusion of 200 ml of a 5% glucose solution, the diagnosis of bilateral renal agenesis was established. Doppler flow study in the umbilical artery revealed a high resistance flow velocity waveform which became normal following amnioinfusion, suggesting cord compression rather than poor uteroplacental perfusion. Abnormal Doppler flow velocity waveforms in the umbilical artery in the presence of severe oligohydramnios should be interpreted with caution.

摘要:

Intrauterine growth retardation is associated with increased perinatal morbidity and mortality. Assuming an accurately dated pregnancy, ultrasonic estimations of fetal weight can be used to predict intrauterine growth retardation. Antenatal detection of this condition will have an impact on management and ideally may improve outcome.

摘要:

With the increasing use of ultrasound examination in the antenatal period the lack of morphological correlates has become a problem. This study was carried out in order to correct this deficiency. An antenatal real-time ultrasound scan of the fetal head was performed and measurements of the biparietal diameter, occipitofrontal diameter, head circumference and cerebral ventricle-to-hemisphere ratio were undertaken in 103 fetuses at 13–24 weeks gestation. After prostaglandin termination of pregnancy, the fetal brains were perfused in situ through the right carotid artery with 10% formal saline. Horizontal slices of the fetal head were cut, photographs were obtained and measurements of the same parameters as in the ultrasound examination were undertaken. There is a significant correlation (p < 0.001) between the ultrasonographic and post-mortem measurements of all parameters. Also several anatomical structures of the fetal brain are now confidently identified in the antenatal ultrasound scan, using the anatomical preparations for compariso

摘要:

The incidence of motor vehicle accidents resulting in trauma in pregnant women is increasing. The best chance for fetal survival is to ensure maternal survival, so awareness of the types of injuries and their presentation after vehicular trauma is of the utmost importance. An algorithm for the approach to diagnosis and fetal therapy based upon obstetrics and trauma care parameters is hereby presented to the trauma team.

摘要:

Recent advances in antenatal diagnosis have stimulated interest in the development of techniques for in utero treatment of fetal abnormalities. This article identifies and discusses the ethical and legal problems which emerge from fetal therapy. Is a fetus a patient? Does the fetus have rights? Who should give consent for the unborn? Does the fetus have redress if it is injured? Could a pregnant woman be forced to undergo treatment which could endanger her life and health for the benefit of the fetus? Answers to these questions are not clear and create in themselves additional queries. Until fetal therapy becomes an accepted medical practice, the resolution of the ethical and legal issues that it provokes will probably remain inconclusive and a matter of concern.
