Contraction stress test by nipple stimulation: efficacy and safety

During a one-year period, 838 nonstress tests, 425 nipple stimulation contraction stress tests (NS-CSTs), and 115 spontaneous CSTs were done. Results were compared to those of NSTs and CSTs done by classic methods during a previous one-year period. The results revealed no hyperstimulation from contraction stress testing with nipple stimulation, and a significant reduction in the time to perform both tests conducted simultaneously when compared to the nonstress test plus classic oxytocin challenge test. The time to perform the combined tests compared to the routine nonstress test was not significantly different. Moreover, a cost-saving was also demonstrated. The combination of the NST and nipple stimulation CST appeared to be safe, efficacious, and cost-effective.
