Ilioinguinal and Iliohypogastric Nerve Block: A Low Fidelity Task Trainer

Abstract

Study Objective

To create and describe a low-fidelity model that highlights key anatomical landmarks for ilioinguinal and iliohypogastric nerve blocks. This cost-effective tool allows trainees to practice and master procedural techniques. By enhancing these skills, the trainer will increase trainees’ confidence in performing nerve blocks to combat postoperative neuropathic pain related to obstetrical and gynecological procedures.

Design

This descriptive educational simulation project reviews the patient population that might benefit from these injections and presents an evidence-based approach for detecting nerve pathways. It describes the materials and methods used to construct the model, providing a side-by-side demonstration of the simulated vs. actual procedural walkthrough of the technique.

Setting

The task trainer is intended for any educational environment (e.g., classroom, procedure lab) using standard table-height positioning to approximate the ergonomics of performing in the clinic or operating room. The low-stakes setting provides an opportunity to practice identifying landmarks and build muscle memory.

Patients or Participants

The model was developed exclusively for simulation-based teaching for OB/GYN residents. No patients or live participants were involved.

Interventions

Cost-effective, accessible supplies were used to construct a model of the lower abdominal tissue planes and landmarks necessary for nerve blocks. The trainer simulates the force required to pop through the fascia into the target foam abdominal wall. This tactile feedback is critical for enhancing trainees’ identification of key anatomy and effective blockade.

Measurements and Primary Results

With supplies valued at about $20 and a design incorporating cadaveric data, the model offers educators a method for teaching spatial awareness and procedural skills.

Conclusion

This abdominal model, made from inexpensive materials, optimizes tactile simulation of ilioinguinal and iliohypogastric nerve blocks. Its simplicity and replicability make it ideal for reinforcing anatomical knowledge and supporting skill development in an educational setting.
