此谓行动倒仆，或从高堕下，伤损胞络，致血下动胎，而血伤气逆者，胎随气上抢心。
其死生之候，其母舌青者，儿死母活；唇口无沫，儿生；唇青沫出者，母子俱死；唇口青舌

二气交击于内，若不时瘥者，其痛冲击胞络，必致动胎，甚则伤堕。
所谓行动时跌倒，或从高处坠落，损伤了胞络，导致出血并扰动胎元，且因血伤而气机逆乱，胎气随逆气上冲心胸。
判断母子生死预后的征象是：若孕妇舌色发青，则胎儿已死而母亲存活；若唇口无泡沫，则母子皆活；若唇色发青且有泡沫溢出，则母子俱亡；若唇口发青而舌色红赤，则母亲死亡而胎儿存活。如果下血不止，胞宫干燥、胎元枯槁，就会导致胎死腹中。
这种情况可能是因为受惊跌倒，或感染温疫、伤寒等外感病邪，邪毒侵入胞脏，导致胎死。其征象表现为胎所在部位感觉寒冷，这是胎已死亡的迹象。
腹痛都是由风邪侵入腑脏，与气血相互搏击所致。妊娠期间，妇女或因体内素有寒性积块（冷疹），或新近感受风邪，邪气结聚而引起疼痛。如果腹痛持续不止，邪气与正气相争，气血紊乱，进而损伤胞络，就会导致胎动不安。
心痛，多由风邪和痰饮乘袭心的经络，邪气与正气搏结，交结在一起而引发疼痛。如果是损伤心脏的正经而痛，称为“真心痛”。心主宰神志，统领各脏腑，本不应受邪气侵袭。如果邪气真的伤了心正经，早晨发病晚上就会死亡，晚上发病早晨就会死亡。如果是损伤心的分支别络而痛，则疼痛时轻时重，发作有定时。妊娠妇女感染此类病症，若疼痛不止，气机上乘侵犯胞络，损伤子宫，就会导致胎动不安。凡是胎动，胎位就会转移不安，若因不安而动及血分，就会出现阴道出血。
妊娠期间出现心腹疼痛，可能是由于腹内素来有寒性积块，或新近触犯风寒，都是因为脏腑虚弱而诱发。邪气与正气相互搏击，并合于气机，随着气机上下运行，上冲于心则引起心痛，下攻于腹则引起腹痛，从而导致心腹俱痛。妊娠期间发生疼痛，是正气与邪气在体内交击，如果不能及时痊愈，疼痛冲击胞络，必然导致胎动不安，严重时甚至会导致流产堕胎。
肾主管腰部和下肢，因劳累损伤而动摇了根本，经脉空虚，风冷之邪趁虚而入，所以导致腰痛。妇人通过肾脉系连胞宫，妊娠期间腰痛严重的，大多会发生堕胎。
This refers to falling due to movement or dropping from a height, damaging the Bao Luo (uterine collateral vessels), causing bleeding that disturbs the fetus, and with blood injury leading to Qi rebellion, the fetal Qi follows the rebellious Qi upward to rush against the heart.
Regarding the prognosis of life and death: if the mother's tongue is cyanotic, the fetus is dead but the mother lives; if the lips and mouth have no foam, both live; if the lips are cyanotic and foam issues forth, both mother and fetus die; if the lips and mouth are cyanotic while the tongue is red, the mother dies but the fetus lives. If bleeding does not cease, the Bao Palace becomes dry and the fetus withers, resulting in fetal death.
This may occur due to fright and falling, or contracting warm epidemic diseases or Taiyang disease (exposure to cold pathogens affecting the exterior), where pathogenic toxins enter the Bao Zang (uterus), causing fetal death. The sign is coldness at the site of the fetus, indicating the fetus has died.
Abdominal pain is caused by Wind pathogen entering the Fu organs and Zang organs, clashing with Blood and Qi. During pregnancy, women may have pre-existing Cold masses (cold-type accumulations) or newly contract Wind pathogen, causing Qi stagnation and pain. If abdominal pain persists, pathogenic factors conflict with healthy Qi, disrupting Blood and Qi, thereby damaging the Bao Luo and causing fetal movement.
Heart pain is mostly caused by Wind pathogen and Phlegm-fluids attacking the meridians and collaterals of the Heart. Pathogenic Qi clashes with Healthy Qi, knotting together to cause pain. If the Zheng Jing (primary meridian) of the Heart is damaged, it is called Zhen Xin Tong (True Heart Pain). The Heart houses the Shen (Spirit) and commands all Zang organs, and should not be invaded by pathogens. If the primary meridian is injured, morning onset leads to evening death, and evening onset leads to morning death. If the Zhi Bie Luo (branch collaterals) of the Heart are injured, pain comes and goes intermittently with regular intervals. When pregnant women contract this illness, persistent pain allows Qi to ascend and attack the Bao Luo, damaging the Zi Zang (uterus), causing fetal movement. Whenever the fetus moves, its position shifts restlessly; if this restlessness disturbs the Blood, vaginal bleeding occurs.
Heart and abdominal pain during pregnancy may stem from pre-existing Cold masses in the abdomen or new exposure to Wind-Cold, triggered by deficiency of the Zang organs. Pathogenic and Healthy Qi clash and merge with Qi, moving up and down; rushing upward to the Heart causes heart pain, attacking downward to the abdomen causes abdominal pain, resulting in both. In pregnancy, pain results from the internal clash of Healthy and Pathogenic Qi. If not healed promptly, the pain impacts the Bao Luo, inevitably disturbing the fetus, and severely, causing miscarriage.
The Kidney governs the waist and legs. Injury from overwork damages the essence, making the meridians deficient, allowing Wind-Cold to invade, thus causing lower back pain. Women's Kidney meridians connect to the Bao Palace. Severe lower back pain during pregnancy often indicates impending miscarriage.
