Abstract

A small sample of fetal blood suitable for studies of haemoglobin synthesis was obtained from a placental vessel under endoscopic visualisation in 23 of 26 patients in whom the procedure was attempted prior to second-trimester abortion. Fetal blood loss, calculated in 23 cases, was between 0-2 ml. and 2-5 ml., and fetal blood-volume depletion varied from 0-5% to 15%. No short-term ill-effects were demonstrated in mother or fetus in any of 16 patients in whom the injection of aborti-facient was postponed for between 16 and 24 hours after the procedure.

The possibility of a universal declaration of biomedical ethics.

Statements on issues in biomedical ethics, purporting to represent international interests, have been put forth by numerous groups. Most of these groups are composed of thinkers in the tradition of European secularism, and do not take into account the values of other ethical systems. One fifth of the world's population is accounted for by Islam, which is a universal religion, with more than 1400 years of scholarship. Although many values are held in common by secular ethical systems and Islam, their inferences are different. The question, "Is it possible to derive a truly universal declaration of biomedical ethics?" is discussed here by examining the value and extent of personal autonomy in Western and Islamic biomedical ethical constructs. These constructs are then tested vis-à-vis the issue of abortion. It is concluded that having a universal declaration of biomedical ethics in practice is not possible, although there are many conceptual similarities and agreements between secular and Islamic value systems, unless a radical paradigm shift occurs in segments of the world's deliberative bodies. The appellation "universal" should not be used on deliberative statements unless the ethical values of all major schools of thought are satisfied.

Information for patients undergoing a prenatal diagnosis.

OBJECTIVES: Lack of information is a frequent complaint with regard to physicians dealing with prenatal diagnosis (PD). The aim of the study was to find out how information on PD was perceived by patients and if they considered that they had been correctly informed by their physicians. METHODS: We conducted a prospective study in Lariboisière Hospital (Paris) with 86 patients undergoing prenatal diagnosis between 2001 and 2003. A 23-item questionnaire was given to patients after delivery or termination of pregnancy (TP). RESULTS: Fifty patients out of 86 answered the questionnaire. Twelve patients out of 50 underwent a TP. Information on foetal anomaly was insufficient for 11 patients out of 50 (22%). Some patients found the information too technical; others would like to see photos to illustrate the anomalies and the possible surgical repairs to be performed. Information was insufficient for one in four patients concerning maternal serum screening for Down's syndrome. Information before amniocentesis was considered sufficient by 9 out of 10 patients. Information on the risks of TP was not given or not understood by 10 out of 12 patients. CONCLUSION: Information on prenatal diagnosis could be improved by using simple and accessible language, supported by written documents and photos for certain anomalies. More information should be given in cases of abstract anomalies and should be adapted to the social, ethnic and cultural background of the patient.
