Intraoperative Management of Postpartum Hemorrhage

Simulation

One time, low-cost, easy-to-create model that is reusable. Cost is $4.50/uterus model (makes three models with supplies listed

Collect all the necessary materials and tools you will need to complete the model.
Print out the stencils and arrange the 6 pieces of paper with ABC in the top row and CDE in the bottom row (Figure 1). Tape them together and cut out the shapes. Use these stencils to trace and cut out the shapes on the felt fabric. To start, you will need the uterus shape in the red fabric, two fallopian tube and ovary shapes, and one bladder shape in the beige fabric (Figure 2). Please see file labeled "Stencils."

Next, fold the uterus shape in half. Thread a needle with black thread and sew along the edges to close the uterus (Figure 3).
Fold one ovary shape in half. Using black thread, sew along the edges to close it, leaving yourself room to stuff it. Stop sewing and stuff the ovary with enough stuffing so it is completely full. Then, finish sewing it closed. Do this with the other ovary shape as well (Figure 4).

Ovary cutouts made with felt.

Now, you will need to attach the ovaries and tubes to the uterus. To do so, measure about 1 inch below the top edge of the uterus and sew the ovaries to the model on both sides (Figure 5).
Next, the uterine artery and vein need to be added to the model. Thread a red and blue string of yarn long enough to traverse the entire model length through a yarn needle (Figure 6). Double the red and blue so that the artery and vein is two strings of yarn thick. Needle that through the lateral edge of the uterus. Repeat it on the other side (Figure 7).

Next, fold the bladder shape in half. Sew it closed most of the way, leaving enough room to stuff it. Once stuffed, sew the bladder shut (Figure 8).
Once the bladder is created, it needs to have the ureters entering it from the back. Using a thicker yarn needle with yellow yarn thread through, insert the ureter into the bladder and come out about 2 inches lateral to it. Repeat this with another yellow string of yarn so the ureter is two strings thick (Figure 9).

Estimate where to make the transverse incision on the uterus by placing the bladder on top of the uterus so the lower edges line up (Figure 10). Once estimated, make a transverse cut about 4 inches wide. Fill the uterus with stuffing through your incision (Figure 11).
Add a small piece of Velcro to the back of your bladder and to your uterus model to attach the bladder to the model (Figure 12).
Cut tubing to a length that will transverse the uterus model. Insert it inside the model and suture it down to the lateral edges of the uterus (Figure 12.).;
The model is now complete and ready to use (Figure 13).
