The survival rate of preterm babies born at 34 weeks of pregnancy is close to 100%, but may be reduced if combined with other life-threatening complications. A fetus that is delivered after 37 weeks of pregnancy is not considered preterm. The survival rate of preterm babies born at 34 weeks of pregnancy needs to be judged in conjunction with the presence of other medical conditions in the fetus. Preterm babies who are able to breathe on their own at birth and weigh more than 4 pounds have a high survival rate. However, if the weight is relatively small or combined with malformations, the survival rate may be low. Nowadays, with the improvement of medical technology, the treatment of the fetus is comprehensive. For example, they are put into a warm box for treatment, and most of the treatments do not affect the normal development of the baby in the future. More attention needs to be paid to good labor and delivery tests during pregnancy to reduce the risk of preterm labor. If the fetus has a tendency to be born prematurely, don’t panic, cooperate with the doctor and use breathing method to cooperate with contractions for a smooth delivery. After delivery, preterm babies can be actively treated.
