(1)Pregnant women should avoid catching colds, especially during early pregnancy. Cold viruses directly affect the mother, while high fever (39°C or higher lasting 24 hours) and toxins from metabolic disruption cause indirect harm. Viruses can cross the placenta into the fetus, potentially causing congenital heart disease, cleft lip, hydrocephalus, anencephaly, microcephaly, and other abnormalities. Bacterial infections increase the risk of cardiovascular malformations in the fetus.Animal studies with Viruzole demonstrate teratogenic and embryotoxic effects; this product is contraindicated for pregnant women.
(2) Between 6-8 weeks gestation, perform chorionic villus sampling for chromosomal analysis; between 16-20 weeks, conduct amniocentesis for chromosomal testing of amniotic fluid cells. Concurrently, monitor maternal alpha-fetoprotein (AFP) levels dynamically. Use ultrasound to track fetal gross morphology and internal organ structure for abnormalities.1. Identify the cause of fever while ensuring adequate nutrition and rest. Beyond determining the cause, moderate fever reduction is necessary for pregnant women. Fever often increases metabolic rate and is accompanied by discomfort such as headaches, loss of appetite, fatigue, palpitations, and even dehydration, placing additional strain on cardiac and pulmonary function.Therefore, moderate fever reduction is advisable. Generally, if the pregnant woman's temperature does not exceed 38.5°C (101.3°F) and there are no significant discomfort symptoms, physical methods can be considered to help reduce the fever. These include using an ice pack pillow, cooling patches, sponging with lukewarm water (using a warm towel to repeatedly wipe the body), and placing ice packs in the armpits, forehead, and groin areas.
2. Use of Antipyretic Medications
Avoid them whenever possible. The decision to use medication varies by individual, but if the temperature exceeds 38.5°C (101.3°F) and is accompanied by discomfort, medication may be considered under a doctor's guidance. Otherwise, it may harm the fetus.
3. Crucial Reminder
The pathogens causing the fever pose a greater risk to both mother and fetus than the fever itself. Therefore, identifying the underlying cause and treating it appropriately is more important than simply reducing the fever. For fevers caused by common colds, the prognosis is generally favorable for both mother and baby.
Immune function often declines during pregnancy, making expectant mothers susceptible to colds.Many respiratory infections are caused by various viruses or bacteria. Certain viruses, such as influenza virus, rubella virus, coxsackievirus, and cytomegalovirus, can infect the fetus through the mother. Early infection may lead to miscarriage, stillbirth, or fetal malformations. Infection during the first trimester, in particular, can cause congenital heart defects in the infant.Rubella virus poses even greater risks to the fetus. Beyond congenital heart defects, it can cause neonatal cataracts, deafness, microcephaly, developmental delays, and low birth weight—a condition medically termed congenital rubella syndrome.
If a mother contracts bacterial infections during late pregnancy, the newborn may develop sepsis after birth, presenting with fever, refusal to feed, severe jaundice, and abnormal white blood cell counts (either elevated or reduced). If infected with cytomegalovirus during mid-to-late pregnancy, the infant may be born with low birth weight, respiratory distress, enlarged liver and spleen, jaundice, pneumonia, or meningoencephalitis.Therefore, women should diligently avoid colds and fevers during pregnancy, with the first trimester being particularly critical. Stay away from individuals with colds, minimize visits to crowded public places like shopping malls and theaters, and seek prompt medical attention if ill. Medications should only be used under a doctor's supervision, selecting options that pose no risk to the fetus.
