dissection of a dead fetus in utero. Applicable particularly to cows because of the size of the uterus and the opportunity to introduce instruments to the full depth of the fetus.
the fetus is dissected through the skin using first a knife to open the skin followed by a fetotome. It is faster than a subcutaneous approach but offers more risk to the uterine wall.
the fetus is entered between the first ribs and the thoracic cage destroyed within the skin. The fetus is extracted when its mass has been reduced by this internal demolition and removal.
