Generally, there are many reasons that can cause symptoms of preterm birth. Normally, due to reasons such as cervical dilation, or the occurrence of regular abdominal pain, preterm labor may be induced. In some cases, long-term vaginal inflammatory conditions can lead to premature rupture of membranes, or cervical canal dilation may also cause preterm birth. If symptoms of preterm birth occur at present, it is necessary to actively suppress contractions, protect the fetus, and provide symptomatic treatment. If this is ineffective, it is advisable to actively prepare for rescuing and caring for the newborn.
