Opening the Femoral Artery

The subject is usually placedonanatomical position on a flat surface; there arefourpossible sites for inserting the perfusing cannula.Theseare both femoral and common carotidarteries.If blockage ofone of the arteries         prevents                      asatisfactory flow of fluid into the body,thenthe other are tried in turn. If none of these sitesgivesa satisfactory         flow,    the                   body    is         unsuitable        for perfusion.Inthiscasethelastresortisliberal intermuscular with embalming needlesand syringes.
