Time to reconsider: Have the 2015 FIGO and 2017 Swedish intrapartum cardiotocogram classifications led us from Charybdis to Scylla?

In 2015, FIGO revised the 1987 intrapartum cardiotocography (CTG) classification (FIGO1987). A less radical FIGO2015 version was introduced in Sweden 2017 (SWE2017). Now, post hoc simulation studies show that and SWE2017 are reliable than (a modified) FIGO1987. shows significantly better interobserver agreement for normal CTG traces FIGO1987, but worse pathological traces. Agreements between templates moderate to good, different classifications of mainly variable decelerations tachycardia cause significant heterogeneities. insufficient sensitivity identify fetal acidemia compared with connection electrocardiogram ST analysis, one study showed no template superior identifying acidemia, a series only academia, FIGO1987 had higher (73% vs. 43%) set an alarm considerably earlier. With SWE2017, operative interventions declined several adverse neonatal outcomes increased significantly. It remains investigate development FIGO2015.
