Amniocentesis is performed at 16-24 weeks of gestation and carries certain risks. The pregnant woman can pass the risk period about 1 week after amniocentesis. Complications such as fetal respiratory distress, rupture of membranes, intrauterine infection, uterine contractions, placental abruption, amniotic fluid embolism, etc. are usually most likely to occur 24 hours after amniocentesis, so pregnant women must pay special attention to their status during this period and inform their obstetrician if they are unwell. Amniocentesis is traumatic and it takes about 1 week for the needle eye to recover. If the pregnant woman does not pay attention to infection and rest after the puncture, this may also lead to infection or other adverse pregnancy consequences. After the puncture, you should follow your obstetrician’s advice and watch for abdominal pain, vaginal bleeding, fever, and regular lower abdominal cramps. In addition, make sure to take enough rest after the puncture, avoid overexertion, prohibit sports activities and sexual life, avoid mood swings, and check the fetus at the obstetrics department 2-3 days after the puncture.
