Development of artificial tissue-like structures for a hybrid epidural anesthesia simulator

Area of Science:

• Anesthesiology and Medical Simulation

Background:

• Epidural space puncture and lumbar puncture are critical blind procedures in anesthesia.
• Current training relies heavily on procedural volume, presenting a challenge for medical novices.
• Existing training methods lack realistic tactile feedback for needle insertion techniques.

Purpose of the Study:

• To develop and validate a novel hybrid simulator, or patient phantom, for training spinal needle insertion procedures.
• To provide a realistic simulation environment for practicing both midline and paramedian approaches.
• To assess the efficacy of the developed phantom in medical education.

Main Methods:

• Development of a hybrid simulator featuring artificial tissues that replicate anatomical structures.
• Validation of the phantom's performance against existing literature data.
• Conducting a study with medical experts to evaluate the simulator's realism and training utility.

Main Results:

• The developed patient phantom successfully replicated the tactile feedback of spinal needle insertion.
• Validation against literature and expert studies confirmed the simulator's effectiveness.
• The phantom demonstrated potential for improving the learning curve of novice practitioners.

Conclusions:

• The developed patient phantom offers a valuable tool for training medical novices in blind spinal procedures.
• This simulation approach can enhance procedural safety and proficiency before clinical application.
• The hybrid simulator represents a significant advancement in anesthesia training methodologies.
