About this work
Charles Rodek 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 fetoscopy 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 analyzer 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."
