What people usually call "painless childbirth" is medically called "labor analgesia" If painless delivery is not performed, prolonged severe pain can increase catecholamines in the mother's body, resulting in increased blood pressure, increased heart rate, and increased risk of fetal hypoxia and acidosis. With the strong support of the National Health Commission, the analgesia rate of childbirth in China has increased from less than 2018% in 10 to about 20%.

Only a small number of pregnant women still have access to childbirth analgesia techniques.
