沈尧封曰，喘有闭、脱二证。下血过多者是脱证。喉中气促，命在须臾，方书虽有参苏饮一方，恐不及
待。恶露不快者是闭证。投夺命丹可定；如不应，当作痰治。此皆急证。更有一种缓者，楼全善所云∶产
后喘者多死。有产二月，洗浴即气喘，坐不得卧者；五月恶风，得暖稍缓。用丹皮、桃仁、桂枝、茯苓、干
姜、枳实、浓朴、桑皮、紫苏、五味、栝蒌，煎服，即卧，其疾如失∶作污血感寒治也。按此亦是痰证，所
以能持久；痰滞阳经，所以恶寒。方中着力在栝蒌、浓朴、炽实、桂枝、茯苓、干姜、五味数味，余皆多赘。
沈尧封曰∶产后发热，所因不同，当与证参看。感冒者鼻塞，亦不可过汗，经有夺血无汗之禁，只宜芎
归汤；停食者嗳腐饱闷，宜平剂消食；血虚发热，无别证者，脉大而芤，宜归、 ；阴虚者烦渴脉细，宜
生地、阿胶；更有一种表热里寒，下利清谷，烦渴恶热，脉微细者，此少阴危证，宜四逆汤。
王孟英按∶暴感发热，可以鼻塞验之。苟胎前伏
邪，娩后陡发者，何尝有头疼、鼻塞之形证乎？虽脉亦有不即显露者，惟舌苔颇有可征∶或浓白而腻，或
黄腻黄燥，或有黑点，或微苔舌赤。或口苦，或口渴，或胸闷，或溲热。此皆温湿、暑热之邪内蕴，世人不
察，再饮以糖酒生化汤之类。则轻者重而重者危。不遇明眼，人亦但知其产亡，而不知其死于何病，误于
何药也。我见实多，每为太息。其后条之乍寒乍热，亦当如是谛察，庶免遗人夭殃也。
沈尧封说，喘证分为闭证和脱证两种。产后下血过多导致的属于脱证。表现为喉中气息急促，生命垂危在顷刻之间，虽然医书中有参苏饮一方，恐怕来不及服用。恶露排出不畅导致的属于闭证。投用夺命丹可以定喘；如果无效，应当按痰证治疗。这些都属于急症。还有一种较为缓慢的，正如楼全善所说：产后喘证大多致死。有的产妇在产后两个月，洗浴后即出现气喘，只能坐着不能躺卧；有的五月时怕风，得到温暖则症状稍缓。使用丹皮、桃仁、桂枝、茯苓、干姜、枳实、厚朴、桑白皮、紫苏、五味子、栝蒌煎服，服药后即可平卧，疾病消失：这是按照污血感寒来治疗的。按此分析这也属于痰证，所以能够持久；痰滞留在阳经，所以怕冷。方中着力于栝蒌、厚朴、枳实、桂枝、茯苓、干姜、五味子这几味药，其余多为赘余。
沈尧封说：产后发热，原因不同，应当结合症状参看。感冒引起的鼻塞，也不可以过度发汗，经典有“夺血者无汗”的禁忌，只适宜用芎归汤；停食引起的嗳气腐臭、饱闷，适宜用平和剂量的消食药；血虚发热，没有其他症状的，脉象大而中空，适宜用当归、川芎；阴虚引起的烦渴、脉细，适宜用地黄、阿胶；还有一种表热里寒，下利清谷（大便中有未消化的食物），烦渴、怕热、脉微细的，这是少阴病的危重证候，适宜用四逆汤。
王孟英按语：暴感发热，可以通过鼻塞来验证。如果是胎前潜伏的病邪，分娩后突然发作的，何尝会有头疼、鼻塞的症状呢？虽然脉象也可能不立即显露，但舌苔很有参考价值：或者浓白而腻，或者黄腻黄燥，或者有黑点，或者舌苔微少而舌质红。或者口苦，或者口渴，或者胸闷，或者小便热。这些都是温湿、暑热之邪内蕴所致，世人没有察觉，再饮用糖酒生化汤之类的药物。那么轻病就会加重，重病就会危及生命。如果不是明眼人诊治，人们只知道产妇死亡，却不知道死于什么病，误用了什么药。我见到的这种情况很多，每每为此叹息。其后条文中提到的忽冷忽热，也应当如此仔细察辨，以免贻误病人导致夭折。
Shen Yaofeng stated that panting (Chuan, 喘) is divided into two syndromes: Excess syndrome (Bi Zheng, 闭证) and Deficiency syndrome (Tuo Zheng, 脱证). Panting caused by excessive postpartum bleeding belongs to the Deficiency syndrome. It presents with rapid breathing from the throat, with life hanging in the balance; although medical texts mention Can Su Yin (Ginseng and Perilla Decoction), it may be too late to use. Panting caused by sluggish lochia discharge belongs to the Excess syndrome. Administering Du Ming Dan (Life-Saving Pill) can stabilize the condition; if ineffective, it should be treated as a Phlegm syndrome. These are all acute conditions. There is another type that is more chronic, as Lou Quanshan said: Postpartum panting often leads to death. For example, some women experience panting after bathing two months after delivery, unable to lie down; others feel aversion to wind in the fifth month, with slight relief when kept warm. A decoction containing Mu Dan Pi (Moutan Cortex), Tao Ren (Persicae Semen), Gui Zhi (Cinnamomi Ramulus), Fu Ling (Poria), Gan Jiang (Zingiberis Rhizoma), Zhi Shi (Aurantii Fructus), Hou Po (Magnoliae Officinalis Cortex), Sang Bai Pi (Mori Radicis Cortex), Zi Su Ye (Perillae Folium), Wu Wei Zi (Schisandrae Fructus), and Gua Lou (Trichosanthis Fructus) was used. After taking it, the patient could lie flat, and the illness disappeared as if lost. This was treated as Cold invading due to stagnant blood. In my analysis, this is also a Phlegm syndrome, which explains why it persists; Phlegm stagnating in the Yang meridians causes aversion to cold. The key herbs in this formula are Gua Lou, Hou Po, Zhi Shi, Gui Zhi, Fu Ling, Gan Jiang, and Wu Wei Zi; the rest are largely superfluous.
Shen Yaofeng stated: The causes of postpartum fever vary and should be evaluated in conjunction with symptoms. If caused by Wind-Cold invasion, there is nasal congestion; however, profuse sweating should not be induced, as classics prohibit sweating in cases of blood loss ("Those who have lost blood should not be sweated"). Only Xiong Gui Tang (Ligusticum and Angelica Decoction) is suitable. If caused by food stagnation, there is belching with a rotten smell and fullness/distension; mild digestive-resolving agents are appropriate. If caused by Blood deficiency fever, without other symptoms, the pulse is large and hollow (Kou Mai, 芤脉); Dang Gui (Angelicae Sinensis Radix) and Chuan Xiong (Ligustici Chuanxiong Rhizoma) are suitable. If caused by Yin deficiency, there is irritability, thirst, and a fine pulse; Sheng Di Huang (Rehmanniae Radix) and E Jiao (Colla Corii Asini) are suitable. Another type involves exterior Heat and interior Cold, with diarrhea containing undigested food, irritability, thirst, aversion to heat, and a faint, fine pulse. This is a critical Shaoyin syndrome (Shaoyin Bing, 少阴病), and Si Ni Tang (Frigid Extremities Decoction) is appropriate.
Wang Mengying added: Acute infection fever can be verified by nasal congestion. However, if latent pathogens from pregnancy suddenly manifest after delivery, do they present with headache or nasal congestion? Although the pulse may not immediately reveal itself, the tongue coating offers significant clues: it may be thick, white, and greasy; yellow, greasy, or dry; have black spots; or have scant coating with a red tongue body. Symptoms may include bitter taste, thirst, chest tightness, or hot urine. These indicate internal accumulation of Warm-Dampness or Summer-Heat pathogens. Unaware of this, people often administer Tangjiu Shenghua Tang (Sugar-Wine Life-Birth Decoction) and similar formulas. Consequently, mild cases become severe, and severe cases become critical. Without expert diagnosis, people only know the woman died, unaware of the specific disease or the erroneous medication. I have witnessed this frequently and often sigh. Regarding the alternating chills and fever mentioned later, such careful observation is also necessary to avoid causing premature death through negligence.
