Cho stitch

Cho described a technique in which a straight number 7 or 8 needle with #1 chromic catgut is used to place sutures in a small rectangular array to compress the anterior and posterior uterine walls against one another at sites of heavy bleeding. The through and through sutures extend from the serosa of the anterior wall to the serosa of the posterior wall. After creating a square, the ends are tied down as tight as possible to compress the myometrium. Two to 5 squares/rectangles are made, as needed.
