EP24.02: Development of a low‐cost fetal pig simulator for ultrasound training in multiple gestations
Year: 2016
Type: conference-abstract
Abstract: Ultrasound evaluation of multiple gestations requires advanced sonographic skills compared to singleton pregnancies (documentation of chorionicity and amnionicity, identification of discordant growth, diagnosis of twin-twin transfusion syndrome). The objective of this study was to develop a realistic, yet low-cost model for ultrasound training in multiple gestations. Fetal pigs (1 to 15 inch size) preserved in formalin of were utilised for the model. They were inserted in polyethylene bags that were then filled with preservative. A simulated placenta(s) was positioned and affixed and the bags were sealed. Each bag(s) simulated a chorion/amniotic sac and ultrasound gel was placed on the surface of each bag to allow the contents of the bags to be imaged on ultrasound. All types of chorionicity and amnionicity can be successfully simulated with the use of this animal based task trainer. With the use of pigs of different sizes within the same model and discordant amounts of fluid, we were also able to reproduce the appearance of selective growth restriction and twin-twin transfusion syndrome (TTTS). The pigs could be repositioned in the bags to alter the fetal presentation. Placement of the bags in a partial pelvis and covering with an opaque ziplock gallon sized bag allowed a testing/competency environment. Appropriate management of multiple gestations is based on the accurate documentation of chorionicity and the timely diagnosis of complications such as TTTS and selective growth restriction. This model is a useful tool that allows trainees to practice ultrasound evaluation of multiple gestations in a non-clinical environment. It provides learners the opportunity to familiarise themselves with findings particular to multiple gestations.
