An Update on International Consensus Guidelines on Cardiotocograph Interpretation

Le résumé fourni par la source

Physiological CTG interpretation refers to the application of knowledge of fetal pathophysiology and responses to hypoxic and non-hypoxic intrauterine stresses when interpreting changes in fetal heart rate observed on the CTG trace. The onset of regular uterine contractions that progressively increase in frequency, duration and strength as labour advances causes intermittent hypoxic stress to fetuses. Most can withstand such interruptions in the delivery of oxygen and transient accumulation of carbon dioxide and metabolic by-products without sustaining tissue hypoxia and the onset of metabolic acidosis or the development of metabolic acidosis in high-priority central organs resulting in neurological injury. International Expert Consensus Guidelines on Physiological CTG interpretation (2018) recommended the exclusion of pre-existing fetal compromise by looking for decompensation of fetal central organs at the start of CTG monitoring and determining features of different types of hypoxia and response to stress. The revised international consensus statement (2024) included relative uteroplacental insufficiency and fetal inflammation (chorioamnionitis) in the classification table.
