Membrane tenting during amniocentesis is a significant cause of dry taps, leading to immediate procedure failure or multiple needle insertions. Because of the increased risk of fetal loss and other minor complications reported with multiple taps, a means of accomplishing fluid retrieval on a single pass is desirable. We describe a new single-pass technique that involves further needle penetration into the posterior myometrium, under ultrasound guidance, physically displacing the obstructing membranes down the shaft away from the tip.
