Ultrasonography

4.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Area of Science:

  • Medical Simulation
  • Obstetrics and Gynecology
  • Medical Education Technology

Background:

  • Amniocentesis and chorionic villous sampling (CVS) are crucial ultrasound-guided obstetric procedures.
  • Decreasing procedural frequency presents challenges for clinician training and skill maintenance.

Purpose of the Study:

  • To develop and evaluate novel 3D-printed simulators for training in ultrasound-guided amniocentesis and CVS.
  • To provide a standardized, reproducible, and realistic training resource.

Main Methods:

  • Utilized 3D printing technology to create anatomical models mimicking the pregnant abdomen and pelvis.
  • Incorporated medical gelatin to enhance realism and tactile feedback.
  • Developed customizable inserts for targeted needle placement practice.

Main Results:

  • The 3D-printed simulators effectively replicate key anatomical features for procedural training.
  • The models facilitate realistic needle targeting and ultrasound guidance practice.
  • The training tool is standardized, reproducible, and enhances skill acquisition.

Conclusions:

  • Novel 3D-printed simulators offer a valuable solution for training clinicians in essential obstetric procedures.
  • These simulators can help maintain and improve proficiency in ultrasound-guided amniocentesis and CVS.
  • The technology provides a safe and effective platform for procedural skill development.
