Panniculus Retractor Use for Visualization of Fetal Anatomy: A Randomized Controlled Trial.

Objective: To evaluate whether use of a panniculus retractor device for pregnant patients with body mass index (BMI) 40 or higher and a panniculus improves the completion rate of the fetal anatomic examination.

Methods: This was a randomized trial in which eligible patients with BMI 40 or higher and a panniculus were randomized to undergo their detailed fetal anatomic examination with a panniculus retractor device in place compared with usual care. The primary outcome was the completion rate of 16 prespecified views from the anatomic examination.
