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
汤洗拭，急用如圣散或一字散掺刷。

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、背心、脐下、双手足心，共七处部位，反复四五次；随后取轻粉半钱（约1.5-2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。如果腹部膨胀，不能吃奶进食，发出呻吟声，到了出生第七天，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，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，腹胀严重似要断裂，大小便均不通畅，也采用前述方法吸吮胸前、背心、手足心、脐下这七处部位，以皮肤出现红赤色为限度，片刻后自然通畅。
《千金方》记载：小儿出生六七日后，其血气收敛形成肌肉组织，此时口、舌、喉、颊内部应清净无物。如果喉部或舌上有像芦管中盛水那样的肿物，或者悬痈（软腭后部的垂状突起）有肿胀隆起者，可以用丝绵缠绕长针，保留刀刃处如粟米大小的面积，用来刺破患处，使青、黄、赤色的血汁流出泄气。刺一次后停止，观察一天，若未消退，次日再刺，最多不超过三次，自然能完全消退；其余微小的未消部分，刺三次也就停止了，自然会消除。有的生在舌下的称为“重舌”，生在颊里及上颚的称为“重龈”（此处原文可能有缺字，通常指重腭或类似病变，依原文直译），生在齿龈上的称为“重龈”。这些都需要刺破放出血汁。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 "locked belly" (Suodu), this condition is caused by heat accumulation in the womb, leading to an excess of heat-toxin that obstructs the anus, causing blockage and loss of lubrication. If stool is not passed by the third day after birth, a woman should immediately rinse her mouth with warm water and perform cupping-like suction on seven areas of the infant: the anterior chest, posterior back, below the umbilicus, and the palms and soles of both hands and feet, repeating this four or five times. Subsequently, dissolve half a qian (approx. 1.5–2 g) of Qinfen (Calomel, Calomelas) with a small amount of honey in warm water, and administer small amounts frequently until defecation occurs. If there is still no passage, it indicates imperforate anus (gangmen neihe); one must penetrate the area with an object to create an opening. A gold hairpin is preferred, followed by a jade hairpin. The pin should be inserted about two cun deep, and Suhexiang Wan (Styrax Pill) should then be inserted into the hole, with relief expected upon fecal discharge. If the abdomen becomes distended, the infant cannot nurse or eat, makes groaning sounds, and reaches the seventh day after birth, survival is unlikely. Tian’s treatment method involves first piercing the anus with a hard green onion stalk; if stool does not pass, follow up with Niuhuang San (Calculus Bovis Powder, see formula for wheezing) administered with Zhusha Wan (Cinnabar Pill), which should show results within one shichen (two hours).
When a newborn presents with severe abdominal distension resembling rupture and obstruction of both urination and defecation, apply the aforementioned suction method to the anterior chest, posterior back, palms, soles, and below the umbilicus—seven areas in total—until the skin turns red. Passage will naturally occur shortly thereafter.
The *Qianjin Fang* states: Six or seven days after birth, the infant’s qi and blood consolidate to form flesh, and the mouth, tongue, throat, and cheeks should be clear. If there are lesions in the throat or on the tongue resembling reed husks filled with water, or if the uvula (xuanyong) shows swelling, wrap silk around a long needle, leaving only a millet-grain-sized portion of the blade exposed, and puncture the lesion to drain the green, yellow, and red bloody fluid. After one puncture, stop and observe for one day. If unresolved, puncture again the next day. No more than three punctures are needed for complete resolution; minor residual issues will also resolve after three punctures. Lesions under the tongue are called Chongshe (Double Tongue); those in the cheeks and upper palate are referred to as Chongyin (Double Gums/Palate); those on the gingiva are also called Chongyin. All require puncturing to drain the bloody fluid. After puncturing, wash and wipe with salt water solution, and immediately apply Rusheng San or Yizi San to the affected area.
Rusheng San
Qianshuang (Lead Frost, Plumbum Carbonas)
Zhen Niuhuang (Real Calculus Bovis, Calculus Bovis)
Taiyin Xuanjingshi (Taiyin Crystal Stone, Selenitum)
Zhusha (Cinnabaris, processed by water levigation and dried)
Grind these four ingredients separately to an extremely fine powder. Weigh exactly two qian five fen (approx. 8–9 g) of each, mix uniformly, add Wulongnao (Borneolum Syntheticum, 0.5 qian), and grind again until uniform. For each use, take an amount equivalent to one zi (approx. 0.3–0.5 g) to half a qian, sprinkle into the infant’s mouth, and use occasionally.
Yizi San
Zhusha (Cinnabaris)
Pengsha (Borax, Boracum) — each half a qian
Longnao (Borneolum Syntheticum)
Puxiao (Natrii Sulfas, Mirabilite) — each one zi (approx. 0.3–0.5 g)
Grind all ingredients into an extremely fine powder. Mix a small amount with honey, dip a goose feather quill into the mixture, and brush it inside the mouth. Swallowing is harmless.
