俗名锁肚，由胎中受热，热毒壅盛，结于肛门，闭而不通，无复滋润，所以如
此。至若第三日不通，急令妇人以温水漱口，吸咂儿前后心、并脐下、手足心、共
七处，凡四五次，仍以轻粉半钱，蜜少许，温水化开，时时将少许服之，以通为度。
如更不通，即是肛门内合，当以物透而通之，金簪为上，玉簪次之，须刺入二寸许，
以苏合香丸纳入孔中，粪出为快。若肚腹膨胀，不能乳食，作呻吟声，至于一七，
难可望其生也。田氏治法，先用硬葱针 肛门，如大便不下，后用牛黄散（方见喘）送朱
砂丸，一时自见。
小儿初生，腹胀欲绝，大小便不通，亦如前法吸咂胸前、背心、手足心、脐下、
七处，以红赤色为度，须臾自通。
《千金》云∶小儿出腹六七日后，其血气收敛成肉，则口舌喉颊里清净也，若喉
里舌上有物如芦箨盛水状者，若悬痈有胀起者，可以绵缠长针留刃处如粟米许大，
以刺决之，令气泄去青黄赤血汁也，一刺之止，消息一日，未消者，来日又刺之，
不过三刺，自消尽，余小小未消，三刺亦止，自然得消也。有着舌下如此者名重舌，
有着颊里及上 如此者名重 ，有着齿龈上者名重龈，皆刺去血汁也。刺后，用盐

俗称为“锁肚”，这是由于胎儿在母体内受热，导致热毒壅盛，结聚于肛门，闭塞不通，失去滋润所致。如果出生后第三天仍不大便，应立即让妇女用温水漱口，吸吮婴儿的前心、后背、脐下、手足心等共七处部位，反复四五次；随后取轻粉半钱（约1.5克），加少许蜂蜜，用温水化开，不时给婴儿服用少量，以大便通畅为度。如果仍然不通，则是肛门内合（先天性肛门闭锁），应当用物体刺破使其通畅，首选金簪，玉簪次之，需刺入约二寸深，然后将苏合香丸纳入孔中，以排出粪便为见效。如果出现腹部膨胀，不能吃奶进食，发出呻吟声，到了出生后第七天，就难以指望存活了。田氏的治疗方法，先用硬葱针刺肛门，如果大便仍不下，随后用牛黄散（方剂见喘证章节）送服朱砂丸，一个时辰内自然见效。
小儿初生时，腹胀严重似欲断绝，大小便均不通，也采用前述方法吸吮胸前、背心、手足心、脐下这七处部位，以皮肤呈现红赤色为限度，片刻之后自然通畅。
《千金方》记载：小儿出生六七日后，其血气收敛成肉，口腔、舌头、咽喉、面颊内部就会变得清净。如果喉咙里或舌头上有像芦花苞盛水那样的东西，或者悬痈（软腭后部赘生物）有肿胀突起者，可以用丝绵缠绕长针，保留刀刃处如粟米大小，用来刺破它，使青、黄、赤色的血汁流出泄气。刺一次后停止，观察一天，未消退的，第二天再刺，不过三次，自然会完全消退。其余微小的未消部分，刺三次也就停止了，自然能消除。长在舌下的此类病症称为“重舌”，长在内颊及上颚的称为“重齶”（注：原文此处可能有缺字或异体字，指重齶），长在齿龈上的称为“重龈”，都是要刺去血汁。刺破后，用盐水汤清洗擦拭，立即使用如圣散或一字散掺刷患处。

Commonly known as "Suodù" (Lock Belly), this condition is caused by heat received in the womb, leading to an accumulation of heat-toxins that knot at the anus, causing blockage and loss of lubrication. If there is no bowel movement by the third day, a woman should immediately rinse her mouth with warm water and perform cupping-like suction on seven areas of the infant: the anterior chest, back, below the umbilicus, and palms/soles of hands and feet, repeating this four or five times. Subsequently, dissolve half a qian (approx. 1.5g) of Fenqing (Calomel, *Hydrargyri Chloridum*) with a small amount of honey in warm water, and administer small amounts frequently until defecation occurs. If still blocked, it indicates imperforate anus (internal closure of the anal canal); one must use an object to pierce and open it. A gold hairpin is best, followed by a jade hairpin. It should be inserted about two cun deep, and then Suhe Xiang Wan (Styrax Pill) is inserted into the hole; relief is achieved when feces are expelled. If abdominal distension occurs, inability to nurse or eat, and moaning sounds persist until the seventh day after birth, survival is unlikely. Tian's treatment method involves first piercing the anus with a hard scallion stalk. If stool does not pass, subsequently administer Zhusha Wan (Cinnabar Pill) sent down with Niuhuang San (Calculus Bovis Powder, see formula for asthma/wheezing), which will naturally take effect within one shichen (two hours).
For infants born with severe abdominal distension resembling impending rupture and blockage of both large and small bowels, the aforementioned suction method is applied to seven areas: anterior chest, back, palms/soles, and below the umbilicus. The procedure continues until the skin turns red, after which patency usually returns spontaneously.
The *Qianjin Fang* states: Six or seven days after birth, as the infant's blood and qi consolidate into flesh, the mouth, tongue, throat, and inner cheeks become clear. If there is a substance in the throat or on the tongue resembling a reed husk holding water, or if the uvula shows swelling/protrusion, wrap silk around a long needle, leaving the blade tip exposed to the size of a millet grain, and puncture it to release the qi and drain blue-yellow-red bloody fluid. Stop after one puncture and observe for a day. If not resolved, puncture again the next day. No more than three punctures are needed for complete resolution. Minor remaining issues also resolve after three punctures. Such conditions located under the tongue are called "Chong She" (Double Tongue); those in the inner cheeks and upper palate are called "Chong E" (Double Palate); those on the gums are called "Cheng Yin" (Double Gums). All require draining of bloody fluid. After puncturing, wash and wipe with salt water solution, and immediately apply Rusheng San or Yizi San to the area.
Rusheng San (Miracle-Resembling Powder)
Qianshuang (Lead Frost, *Plumbii Carbonas*), Zhen Niuhuang (Real Calculus Bovis, *Bovis Calculus*), Taiyin Xuanjingshi (Taiyin Crystal Stone, *Selenitum*), Zhusha (Cinnabaris, processed by water levigation and dried).
These four ingredients are each ground to an extremely fine powder, weighed accurately at 2.5 qian each, mixed uniformly, and 0.5 qian of Bailongnao (White Borneol, *Borneolum Syntheticum*) is added and ground again until uniform. Each time, take a yizi (approx. 0.3-0.5g) to half a qian, sprinkle only into the infant's mouth, and use occasionally.
Yizi San (One-Yizi Powder)
Zhusha (Cinnabaris), Pengsha (Borax, *Borax*), Longnao (Borneol, *Borneolum*), Puxiao (Niter, *Natrii Sulfas*).
Each ingredient is present in the specified amounts (Pengsha and Zhusha: half a qian each; Longnao and Puxiao: one yizi each). Grind all into an extremely fine powder. Mix with a small amount of honey, dip a goose feather quill into the mixture, and brush inside the mouth. Swallowing is harmless.
