ABSTRACT
The 4 ml of blue dye can be divided into four separate injections, one into each quadrant of the cervix (1 ml each). Alternatively, the injections can be given at the 3 and 9 o’clock positions, which correspond more to the parametria and avoid blue dye staining of the bladder flap secondary to the 12 o’clock injection. After the injection, the patient is prepped and draped in the usual sterile fashion. The procedure continues as planned, either through laparoscopy or laparotomy. The sentinel node identification and removal is performed first. If no blue nodes are noted, a second injection of 2 ml of blue dye can be injected directly into the cervix.
