Simulation training has become the cornerstone of procedural training in neonatal intensive care (1). The use of animal models such as anesthetized kittens, rabbits, ferrets, and chickens has fallen out of favor for ethical and logistic concerns (2, 3, 4, 5). Increasingly sophisticated high-fidelity simulation models have been developed, but they are often expensive and unaffordable. Additionally, it is not clear that high-fidelity models offer major advantages in procedural training when compared to low-fidelity models (6).

In this chapter we describe how to make relatively inexpensive models for vital neonatal procedures, using materials that are easily available. These models have been used in training boot camps for Neonatal Perinatal Fellows and in Procedure Workshops at National Conferences. Other lowcost simulation models have been described in the literature for umbilical catheterization and for circumcision (7, 8). There are quality commercial models available for neonatal intubation and lumbar puncture, procedures for which lowcost simulation models are urgently required.

Simulation training is most effective in temporal proximity to the time when the skills are likely to be used and frequent refresher training should be considered to prevent skills decay (9, 10, 11). The use of check lists (see Appendix A) to monitor and document compliance with all steps of the procedures is encouraged for competency training. Repeated training improves technique and reduces number of overall attempts (11). Team-based training to improve team work and communication, particularly for emergency scenarios, is vital to improve performance in real-life situations (12, 13).


A. Equipment (Additional Model-Specific Equipment Is Listed for Each Model)

1. Polyurethane/vinyl or silicone baby dolls, 8 to 20” long, with hollow torsos

2. Craft knife—hobby/exacto or box cutter

3. Scissors

4. Thick shelf liner (e.g., Nonadhesive Grip Premium Liner, Con-Tact Brand, Kittrich Corporation, La Mirada, CA)

5. Vinyl or latex gloves—skin colored

6. Food coloring—red and yellow

7. Duct tape or similar strong tape

8. Water

9. Permanent marker


B. Chest Tube Model (14)

This model may be used for thoracocentesis and chest tube placement simulations.

1. Equipment (in addition to the equipment listed in A):

a. Electrical cable wire (14 gauge)

b. Styrofoam pieces

c. Inflated sandwich bags or bubble wrap with large bubbles

2. Procedure

a. Cut away the anterior chest and abdominal wall of the doll (Fig. 2.1)

b. Construct the clavicles and rib cage using 14-gauge electrical wire and tape (Fig. 2.2)

c. Place styrofoam block in the middle of the rib cage to create two pleural cavities, and place inflated sandwich bags inside each cavity to simulate pneumothorax (Fig. 2.3)

d. Wrap chest model with thick shelf liner (simulates muscle layer) (Fig. 2.3)

e. Place inside chest cavity of hollow doll (Fig. 2.4)
