About this work

Description

Professor Frank Hytten, in discussion with Mr Geoffrey Chamberlain, talks about the metabolism of water during pregnancy. Two aspects of water metabolism are considered. The first centres on the fact that in early pregnancy plasma osmolality falls, a fact which is largely due to the effect of overbreathing - the mother avoids a state of diabetes insipidus by 'resetting' her osmo-receptors. The second is the phenomenon of water storage in pregnancy - an average of 2 1/2 litres in excess of that usually stored in known sites of tissue growth which, in some individuals, can rise to as much as 8 litres. They argue, however, that oedema is universal in healthy pregnant women and attempts to change it using drug therapy is dangerous to both mother and child.

Notes

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.
