To summarize the experience of perinatal nursing for 27 days of delayed delivery of the second fetus of a twin pregnancy with placenta previa. Key nursing points include:the start of high risk warning during delayed delivery,and being alert to placenta previa hemorrhage;effective prevention of infection,reducing the incidence of maternal sepsis and chorioamnionitis;actively inhibiting the contractions to prolong gestational age and improving the perinatal survival rate of the second fetus;strengthening in utero fetal monitoring,identifying the early signs of fetal distress;targeted implementation of personalized psychological nursing,to ensure the mental health of patients. The rescue plan during delivery should be improved to ensure the safety of mother and child. Postpartum prevention and treatment of massive bleeding was actively conducted, as well as the prevention of puerperal infection. After 79 d of active treatment and intensive nursing care,the patient was treated and discharged from the hospital without any signs of infection or a massive bleeding. The second newborn,whose delivery was delayed,was discharged from the hospital 59 d after birth,and the follow up was continued for a month until the reach to the standard growth development parameters and the overall physical examination was good.
