新产后的脉象若呈现缓滑之象为吉兆。若脉象实大、弦急，则预示死期临近。若脉象沉重而小，亦为吉兆。若脉象突然变得坚牢，则生命难保。寸口脉若涩（血液运行不畅）且疾速不调，主死；若脉象沉细，按至骨部仍有根气不绝，主生。仔细审视这些征候并清晰牢记，长久以来需遵循向心经（《脉诀》中的特定篇章或理论体系）的指引。
《脉经》记载：产后寸口脉疾速不调者死，沉微而按之不绝者生。现今《脉诀》将《脉经》的内容改编为歌诀，既然使用了原文，却不阐明其原理，擅自将“焱”（yàn，火貌，此处指脉来急促如火）改为“涩”。其用意似乎是认为涩滞与疾驶并行，才能称为“不调”，反而认为“焱疾”是不对的。这是不懂得脉涩则不疾，脉疾则不涩的道理。所谓“不调”，是因为脉来疾速。产后失血多，五脏虚弱，所以脉象表现为缓、滑、沉、微且不绝，是符合病情的脉象。“涩”脉因少血也是应病的脉象。唯独“焱疾不调匀”，意味着脉形速度过快，浮越于上，所以说主死。仅仅一字之差，生死结果截然不同。
通真子说：经典记载六岁以下为小儿，十八岁以下为少年，二十岁以上为壮年，五十岁以上为老年。对于六岁以下，经典中未详细记载。因此，吃奶以下的婴儿患病难以治疗，因为没有明确的脉象可供考证。中古时期有巫方创立《小儿颅囟经》，通过占卜夭寿、疾病、生死来相传习用，其中有专门针对幼小的方剂。到了晋宋时期，推崇苏氏家族的方法。又有巢元方撰写《诸病源候论·小儿病源候论》。现今《脉诀》中的这首歌诀，不过是上述内容的万分之一罢了。我认为自宋代以来，专门从事儿科诊疗的人稍多，如钱乙、朱震亨、张杲等医家，以及《幼幼新书》、《全婴书》、《婴孩宝鉴》、《活幼口议》、冯氏《妙选宝秘方》及各家的名方，必须广泛博览方可掌握。况且小儿的脉象，应当用医生大拇指辗转分按三部脉。而且小儿脉象尚未定型，应当以观察神色形态为上策。各种胎中病、变蒸（婴幼儿生长发育过程中的生理现象）、五疳（五种小儿慢性消耗性疾病）、急慢惊风、疮疹等，与成人不同。其他杂病，治疗方法与成人相同，只是药剂的大小轻重有所不同。
小儿在哺乳后出现呕吐逆乱，再加上脉象紊乱，无需过度忧虑。
《脉经》记载：这是因为天数已到应变蒸的时候，身体发热，脉象紊乱，无汗，不想进食，进食就呕吐，这是脉乱而无痛苦的表现。
脉象弦急时是被气机缠阻。脉象〔缓〕（此处应为沉）只是乳食不消化。
《脉经》记载：小儿脉沉表示食积不消。《脉诀》说是“缓”，这是错误的。
脉象紧数细快也较少痛苦。〔虚濡邪气惊风助〕（正确的说法应是：脉紧乃是风痫痼疾。）
《脉经》记载：紧脉主风痫，《本事方》观点相同。现在《脉诀》说是“虚濡”，这是错误的。
腹泻、肠道急痛之时，若见浮大之脉，则归入死亡之路（泉路）。
这并非《脉经》小儿脉篇所述内容，已在下利微小却为生证中详解。《脉经》略举几种脉象立证以完备书籍内容，是一脉自成一证。李范乃将吐后脉证总括起来，见解为何如此不明？况且小儿呕吐有多种情况，现在所说的脉乱之吐，乃是变蒸之候的歌诀解释。
The pulse after new childbirth, if slow and slippery (smooth), is auspicious. If the pulse is full, large, wiry, and rapid, death approaches. If it is heavy and small, it is auspicious. If it suddenly becomes firm and solid, life cannot be sustained. If the Cun Kou (Inch Port) pulse is choppy (indicating sluggish blood flow) and rapid and irregular, it indicates death; if it is deep and fine, yet unceasing when pressed to the bone, it indicates survival. Carefully examine these signs and record them clearly; one must long adhere to the teachings of the Xiang Xin Jing (Heart-Oriented Classic).
The *Mai Jing* (Pulse Classic) states: "If the Cun Kou pulse after childbirth is rapid and irregular, death ensues; if it is deep and faint but unceasing upon pressing to the bone, survival ensues." The current *Mai Jue* (Pulse Rhymes) adapts the content of the *Mai Jing* into verse. Having used its text, it fails to clarify its rationale and arbitrarily changes "Yan" (flaming/rapid) to "Se" (choppy). Its intent seems to be that only a combination of sluggishness and rapidity can be termed "irregular," thereby regarding "rapid/flaming" as incorrect. This demonstrates a lack of understanding that a choppy pulse is not rapid, and a rapid pulse is not choppy. The term "irregular" here refers to the rapidity. After childbirth, due to significant blood loss and deficiency of the five Zang organs, pulses that are slow, slippery, deep, faint, and unceasing correspond to the disease condition. A choppy pulse, resulting from blood deficiency, also corresponds to the disease condition. Only when the pulse is "rapid and irregularly uniform," indicating excessive speed and floating upward, does it indicate death. A difference of a single character leads to opposite outcomes in life and death.
Tong Zhen Zi said: The classics state that those under six years old are infants, those under eighteen are youths, those over twenty are adults, and those over fifty are elderly. For those under six, the classics do not elaborate. Therefore, illnesses in nursing infants are difficult to treat because there are no definitive pulses to examine. In ancient times, Wu Fang established the *Xiao Er Lu Xin Jing* (Classic of Infant Skull Fontanelles), using divination to predict longevity, illness, and death, which was passed down and practiced. It contained prescriptions for the young. By the Jin and Song dynasties, the Su family's methods were promoted. Chao Yuanfang then authored the *Zhu Bing Yuan Hou Lun* (General Treatise on the Causes and Symptoms of All Diseases), including sections on infant diseases. The song in the current *Mai Jue* represents merely one ten-thousandth of this knowledge. I believe that since the Song dynasty, specialists in pediatrics have become more numerous, such as Qian Yi, Zhu Zhenheng, Zhang Guo, and texts like *You You Xin Shu*, *Quan Ying Shu*, *Ying Hai Bao Jian*, *Huo You Kou Yi*, Feng Shi's *Miao Xuan Bao Mi Fang*, and various famous prescriptions. One must study extensively. Moreover, the infant's pulse should be examined by rolling the doctor's thumb across the three positions. Since the infant's pulse is not yet fixed, observing facial features and physical form is the superior method. Conditions such as prenatal diseases, Bian Zheng (physiological developmental phases), five types of Gan syndrome (chronic wasting diseases), acute and chronic convulsions, and rashes differ significantly from adults. Other miscellaneous diseases are treated similarly to adults, but the dosage and weight of medicines vary.
When an infant vomits or regurgitates after feeding, accompanied by a chaotic pulse, there is no need for undue worry.
The *Mai Jing* states: "This occurs during the days designated for Bian Zheng. The body is hot, the pulse is chaotic, there is no sweat, appetite is lost, and vomiting follows eating. Chaotic pulse without suffering."
When the pulse is wiry and rapid, it is entangled by Qi stagnation. A [slow] (should be deep) pulse simply indicates undigested milk.
The *Mai Jing* states: "An infant's deep pulse indicates indigestion." The *Mai Jue* says "slow," which is incorrect.
A tight, rapid, fine, and fast pulse also implies little suffering. [Deficient and soggy, aided by pathogenic factors and wind-convulsion] (The correct statement is: A tight pulse indicates wind-epilepsy.)
The *Mai Jing* states: "Tightness indicates wind-epilepsy," consistent with *Ben Shi Fang*. The current *Mai Jue* claims "deficient and soggy," which is incorrect.
During diarrhea and urgent intestinal pain, if a floating and large pulse appears, it leads to the path of the springs (death).
This is not described in the *Mai Jing*'s section on infant pulses; it has been detailed below where a minute and small pulse indicates survival after diarrhea. The *Mai Jing* briefly lists several pulses to establish syndromes to complete the book, treating each pulse as a separate syndrome. Li Fan-nai summarizes post-vomiting pulse syndromes; how can his insight be so unclear? Furthermore, infant vomiting has several types. The chaotic pulse vomiting mentioned here refers to the symptoms of Bian Zheng as explained in the song.
