Clinical Updates on Management & Outcomes of Extreme Preterm Birth

For prevention of preterm birth, the panel recommended the following:

• “Both partners should stop smoking; even smoking cessation during pregnancy protects against preterm birth. Behavioural interventions for smoking cessation during pregnancy are effective, but evidence for the efficacy of drugs or nicotine replacement therapy is limited
• Optimise care of existing maternal medical diseases such as hypertension, diabetes and thyroid disorders
• Advice on healthy diet and exercise as being underweight or overweight increases the risk of complications including congenital anomalies, pre-eclampsia and small for gestational age, all of which may contribute to extreme preterm delivery
• Advise women before conceiving to reduce alcohol and caffeine consumption, stop recreational drugs, take folic acid, and ensure adequate vitamin D intake
• Screen for sexually transmitted infections in higher-risk women as these are associated with preterm birth
• Consider mid-stream urine culture (MSU) in early pregnancy as asymptomatic urinary tract infection and pyelonephritis is associated with preterm birth
• Low dose aspirin begun before 16 weeks of gestation reduces the risk of pre-eclampsia, fetal growth restriction and associated preterm birth
• Other interventions to reduce preterm birth include vaginal progestogen and cervical cerclage”.
