About this work


Charles Rodeck from King's College Hospital discusses fetoscopy and fetal blood sampling. The following summary accompanies the cassette: "Some of the uses of blood sampling and fetal examination by foetoscopy are mentioned. The Needlescope is demonstrated and the technique for its use is described. Real-time scanning immediately before the insertion of the fetoscope is an essential part of the procedure. It ensures selection of the optimal entry-point so that damage to fetus and placenta is avoided, and access is gained to the fetal region to be examined or to the cord insertion for blood sampling. A particle-size analyser provides immediate information on the quality of blood specimens. A film sequence shows a fetus being examined and blood being sampled. With this technique, pure fetal blood can be obtained in over 95% of cases when the sampling is performed between 18 and 22 weeks gestation. The results of diagnostic cases are shown and the risks discussed."

This video is one of around 310 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and 1980s, thus constituting a contemporary medical-historical archive of great interest. The lectures mostly take place in a small and intimate studio setting and are often face-to-face. The lecturers use a wide variety of resources to illustrate their points, including film clips, slides, graphs, animated diagrams, charts and tables as well as 3-dimensional models and display boards with movable pieces. Some of the lecturers are telegenic while some are clearly less comfortable about being recorded; all are experts in their field and show great enthusiasm to share both the latest research and the historical context of their specialist areas.


Segment 1 Chamberlain introduces the discussion and is shown seated with Rodeck. Rodeck describes how fetoscopy is a new technique in prenatal diagnosis and describes which conditions it can be used to diagnose. Time start: 00:00:00:00 Time end: 00:05:30:14 Length: 00:05:30:14
Segment 2 Rodeck demonstrates how a fetoscope works. He shows a diagram detailing fetoscopic sampling from cord insertion. A short film is shown in which images of a fetus are seen down a fetoscope. Time start: 00:05:30:14 Time end: 00:12:22:00 Length: 00:06:52:00
Segment 3 Rodeck refers to a table which lists various results of fetal blood sampling. Time start: 00:12:22:00 Time end: 00:16:57:00 Length: 00:04:35:00
Segment 4 Chamberlain and Rodeck are shown seated in discussion. They talk about the value of fetal blood sampling in terms of hospital budgets and the rarity of conditions it can diagnose. They also talk about the safety of the procedure. Time start: 00:16:57:00 Time end: 00:23:14:15 Length: 00:06:17:15
Segment 5 The discussion between Chamberlain and Rodeck continues. They talk about various conditions that benefit from diagnosis by fetal blood testing and look to the future of it as a diagnostic tool. Time start: 00:23:14:15 Time end: 00:28:43:08 Length: 00:05:08:18
