Overview
Clinical Frame
High risk pregnancy is a changing assessment, not a label that automatically predicts operative birth.
High-risk pregnancy is a changing assessment, not a label that automatically predicts operative birth. Maternal hypertension, diabetes, bleeding, placental dysfunction, infection, fetal growth restriction, and preterm labour can reduce fetal reserve or make labour less tolerable. The nurse connects maternal findings with the fetal response: blood pressure and perfusion, bleeding and uterine tone, contraction pattern, symptoms of end-organ injury, and fetal heart rate changes are parts of the same clinical picture. Canadian practice separates antepartum fetal surveillance from intrapartum fetal health surveillance. SOGC Guideline No. 441 addresses testing before labour; Guideline No. 396 addresses fetal surveillance during labour. Intrapartum tracings are classified as NORMAL, ATYPICAL, or ABNORMAL, rather than by the US NICHD Category I, II, and III system. The classification is meant to trigger a graded assessment and response. It is not an automatic order for caesarean birth. A reassuring fetal response provides time to correct a reversible cause. A deteriorating tracing accompanying maternal hypotension, severe hypertension, bleeding, tachysystole, or worsening symptoms requires simultaneous maternal stabilisation and obstetric escalation.
