《产宝百问》曰∶胎前喘息，皆由荣卫之气流行失度。气经于脏，脏不能受，诸气上并于肺，肺隘而气争，
故令喘。其始得之，或因恐坠则精却，却则上焦闭而气不行，则留于肝，肝乘于肺，此喘出于肝也。或因惊恐，
惊则心无所根据，神无所归，气乱于中，心乘于肺，此喘出于心也。或因堕水跌仆，肾气暴动，伤而不通，气留于
肾，肾气上乘于肺，此喘出于肾也。或因饱食过伤。动作用力，谷气不行，脾气逆肺，此喘出于脾也。诸脏相
乘为喘，名各不同。
朱丹溪曰∶妊娠因火动胎，逆上作喘，急则用条芩、香附为末，水调服。
吕沧洲曰∶有妇胎死于腹，病喘不得卧，医以风邪伤肺治之。诊其脉，气口盛人迎一倍，左关弦动而疾，
两尺俱短而离经，因曰∶病盖得之毒药动血，以致胎死不下，奔迫而上冲，非风寒作喘也。大剂芎归汤，加催生
药服之，夜半果下一死胎而喘止。其夫曰∶病
外家诚有怀，以室人见嫉，故药去之，众所不知也。
慎斋按∶以上三条，序胎前有喘证也。《内经》论喘属于肺经为病。若妊娠气喘，有乍感风寒而不得卧者，
客邪胜也。发散自愈，参苏饮主之，三拗汤在所斟酌。若脾虚四肢无力，肺虚不任风寒，肾虚腰酸，短气不能
步，猝然气喘不息。此脾肺素亏，母虚子亦虚，肾气不归元而上乘于肺也。生脉散、补中汤去升、柴，加沉香、
补骨主之。《产宝》一条，是泛论喘证，有五脏相乘，非论胎前病也。丹溪火动作喘，此胎前最多，至于毒
药伤胎病喘，时俗往往有之，病机之不可不察者也。
"Chanbao Baiwen" states: Panting during pregnancy is caused by the irregular flow of Ying and Wei Qi (Qi circulating within the vessels and outside the vessels). When Qi passes through the Zang organs, the organs cannot accommodate it; various Qi gather upward into the Lung, causing narrowing of the Lung orifices and contention of Qi, thus leading to panting. Initially, it may occur due to fear of falling, which causes Jing Essence to retreat. As Jing Essence retreats, the Upper Jiao becomes blocked and Qi fails to circulate, remaining in the Liver. The Liver Qi then overacts on the Lung; this panting originates from the Liver. It may also result from fright; fright causes the Heart Spirit to have no foundation and the Shen (Spirit) to have no abode, leading to chaotic Qi in the Middle Jiao. The Heart Qi then overacts on the Lung; this panting originates from the Heart. It may also stem from falling into water or physical trauma, causing sudden agitation of Kidney Qi. Injury leads to obstruction, Qi remains in the Kidney, and Kidney Qi ascends to attack the Lung; this panting originates from the Kidney. It may also be due to excessive eating causing damage, or strenuous activity, where Grain Qi fails to transform. Spleen Qi rebels against the Lung; this panting originates from the Spleen. Various Zang organs overacting upon each other cause panting, with different names for each.
Zhu Danxi stated: During pregnancy, if Fire disturbs the Fetus, causing Qi to rebel upward and induce panting, in urgent cases, use Huangqin (Scutellariae Radix) and Xiangfu (Cyperi Rhizoma) ground into powder, taken with water.
Luzhang Zhou said: There was a woman whose fetus had died in the abdomen, suffering from panting that prevented her from lying down. The physician treated it as Wind pathogen injuring the Lung. Upon palpating the pulse, the Qikou pulse was one times larger than the Renying pulse; the Guan position on the left was wiry, moving, and rapid; both Chi positions were short and deviated from the normal meridian pattern. He said: This illness likely resulted from toxic drugs disturbing Blood, causing the dead fetus to remain inside. The violent rushing upward of Qi is not panting caused by Wind-Cold. A large dose of Xionggui Tang (Angelica and Chuanxiong Decoction), added with emmenagogue and parturition-inducing herbs, was administered. At midnight, a dead fetus was indeed expelled, and the panting ceased. The husband said: My mother-in-law was indeed pregnant, but because my wife was jealous, she used drugs to abort it. This was unknown to others.
Shenzhai commented: The above three passages describe the occurrence of panting syndromes before/during pregnancy. "Neijing" discusses panting as a disease of the Lung Meridian. If there is panting during pregnancy accompanied by sudden exposure to Wind-Cold and inability to lie flat, it is due to excess external pathogens. Dispersing treatment will lead to self-healing; Shensu Yin (Ginseng and Perilla Leaf Decoction) is the main formula, while San'ao Tang (Three Unblocking Decoction) should be considered with caution. If there is Spleen deficiency causing weakness in the four limbs, Lung deficiency failing to withstand Wind-Cold, Kidney deficiency causing soreness in the lower back, shortness of breath preventing walking, and sudden incessant panting, this indicates inherent deficiency of Spleen and Lung. The Mother's deficiency leads to the Child's deficiency, and Kidney Qi fails to return to its root, instead ascending to attack the Lung. The main formulas are Shengmai San (Generate the Pulse Powder) and Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with Shengma (Cimicifugae Rhizoma) and Chaihu (Bupleuri Radix) removed, plus Chenxiang (Aquilariae Lignum Resinatum) and Buguzhi (Psoraleae Fructus). The passage from "Chanbao" is a general discussion of panting syndromes involving mutual overaction of the Five Zang organs, not specifically discussing diseases of pregnancy. Danxi’s discussion of panting caused by Fire is most common in pregnancy. As for panting caused by toxic drugs damaging the fetus, it often occurs in popular practice; the pathogenesis must be carefully examined.
