新产之脉缓滑吉。实大弦急死来侵。若得沉重小者吉。忽若坚牢命不停。寸口〔涩〕（焱）疾不
调死。沉细附骨不绝生。审看此候分明记。长须念取向心经。
脉经曰。产后寸口脉焱疾不调者死。沉微附骨不绝者生。今脉诀述脉经作歌。既用其文。不明
其理。擅改焱为涩。其意以为涩滞疾驶并行。方可言不调。反以焱疾为非。是不知脉涩则不疾。脉疾
则不涩。其不调者。以焱疾也。产后失血多。五脏虚。故以缓滑沉微不绝为脉应病。涩为少血亦应
病之脉。惟焱疾不调匀。则脉形之速。焱浮于上。故云死。一字之差。生死顿异。

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.
