总括
小儿暑病，有四证焉。中暑为阳邪，单中暑热也，身热有汗。伤暑为阴邪，中暑复感寒也，身热无汗。中暑热极攻
肝，则抽搐。如攻心，则厥冒不知人事也。
中暑
中暑之证，汗出，身体壮热，因暑热熏蒸。故头痛，口大渴，烦躁不宁，甚则气乏神倦，两足寒冷，须以加味人参
白虎汤极灵。
伤暑
小儿伤暑，谓受暑复感寒风也。其证无汗发热，口渴，面色赤红，干呕恶中，腹中绞痛，嗜卧懒食，四肢重疼也。
当用内清外散之法，以二香饮极效。若正气虚弱，当补正除邪，以六君子汤奏功。若伤暑夹食，必恶食多吐泻，以加味
香薷饮治之最灵也。
暑风
暑风者，手足抽搐，状似惊风者也。由暑热攻肝，内伤风病。其证烦渴有汗，身热，二便黄红。先用加味香薷饮疏
其风，继用玉露散清其热，暑热一解，而搐自宁矣。切不可作惊痫治之。
暑厥
暑厥之证，昏眩不知人事者。因其人元气素虚。暑热夹痰，上冲于心，以致精神昏愦。虚者以清暑益气汤治之，若
夹痰者，以辰砂益元散、抱龙丸均可治也。
总括
霍乱者，乃风寒暑饮之杂邪为病而成。卒然挥霍变乱，吐泻交作，腹心疼痛也。其能吐能泻者，乃饮暑盛，谓之湿
霍乱。夫饮暑虽盛，若已经吐泻，其邪即解，故易治也。若欲吐不能，欲泻不能，乃寒胜则凝也，为干霍乱。盖既不吐
泻，则邪无去路，故症不轻也。
湿霍乱
如暑饮合邪，其证吐泻不已，肚腹频痛，口渴引饮，胸膈闷膨。饮盛者，主以二香饮治之；暑盛者，以辰砂益元散
治之，则暑饮之邪清，而霍乱之证愈，其功最灵也。
干霍乱
如欲吐不吐，欲泻不泻，乃寒暑凝结，腹中绞痛，不能堪当，俗名绞肠痧病也。治者当分寒暑，如烦渴大饮者为热，
以桂苓甘露饮主之；若四肢厥逆，口不渴，理中汤煎服。
General Overview
Pediatric heatstroke diseases have four types. Heatstroke (Zhongshu) is caused by Yang pathogenic factors, involving only the contraction of summer-heat, manifesting as fever with sweating. Summer-heat injury (Shangshu) is caused by Yin pathogenic factors, occurring when summer-heat is compounded by cold, manifesting as fever without sweating. If extreme summer-heat attacks the Liver, convulsions occur. If it attacks the Heart, it leads to cold extremities, fainting, and loss of consciousness.
Heatstroke
The syndrome of heatstroke manifests as sweating and high fever due to the steaming effect of summer-heat. Consequently, headache, extreme thirst, restlessness, and irritability occur. In severe cases, there is Qi deficiency with mental fatigue, and coldness in both legs. Jiawei Renshen Baihu Tang (Modified Ginseng and White Tiger Decoction) must be used for excellent efficacy.
Summer-heat Injury
Pediatric summer-heat injury refers to contracting summer-heat followed by exposure to wind-cold. The symptoms include fever without sweating, thirst, reddish complexion, dry retching, nausea, abdominal colic, lethargy, anorexia, and heavy, painful limbs. The treatment method should be internal clearing and external dispersing; Erxiang Yin (Two Fragrances Infusion) is highly effective. If the healthy Qi is deficient, tonifying the healthy Qi to eliminate pathogens using Liujunzi Tang (Six Gentlemen Decoction) yields results. If summer-heat injury is complicated by food stagnation, leading to aversion to food and frequent vomiting and diarrhea, Jiawei Xiangru Yin (Modified Mosla Infusion) is the most efficacious treatment.
Summer-wind Convulsion
Summer-wind convulsion presents with twitching of hands and feet, resembling wind-stroke or convulsive disorders. It arises from summer-heat attacking the Liver and injuring the interior with wind pathogens. Symptoms include irritability, thirst, sweating, fever, and yellow-red urine and stool. First, use Jiawei Xiangru Yin to disperse wind; subsequently, use Yulu San (Jade Dew Powder) to clear heat. Once the summer-heat is resolved, the convulsions cease naturally. It must not be treated as epilepsy or wind-stroke.
Summer-jue (Syncope)
The syndrome of summer-jue manifests as dizziness, fainting, and loss of consciousness. This is because the patient's primordial Qi has always been deficient. Summer-heat combined with phlegm rushes upward to the Heart, causing mental confusion. For those with deficiency, Qingshu Yiqi Tang (Clear Summer-heat and Tonify Qi Decoction) is used. For those with phlegm accumulation, Chensha Yi Yuan San (Cinnabar and Yi Yuan Powder) or Baolong Wan (Embracing Dragon Pill) can be used.
General Overview
Huoluan (Vomiting and Diarrhea Syndrome) is caused by mixed pathogens such as wind, cold, summer-heat, and dampness. It occurs suddenly with chaotic vomiting and diarrhea accompanied by heart and abdominal pain. Cases where vomiting and diarrhea occur are due to abundant summer-dampness and are called Damp Huoluan. Although summer-dampness is abundant, if vomiting and diarrhea have occurred, the pathogen is expelled, making it easy to treat. Cases where one desires to vomit but cannot, and desires to defecate but cannot, are due to cold excess causing stagnation, known as Dry Huoluan. Since there is no outlet for vomiting or defecation, the pathogen remains trapped, making the condition serious.
Damp Huoluan
When summer-heat and dampness combine, symptoms include incessant vomiting and diarrhea, frequent abdominal pain, thirst with desire to drink, and chest/epigastric stuffiness and distension. For abundant summer-dampness, Erxiang Yin is the primary treatment; for abundant summer-heat, Chensha Yi Yuan San is used. This clears the summer-dampness pathogen and cures the Huoluan syndrome with excellent efficacy.
Dry Huoluan
Desiring to vomit but unable, and desiring to defecate but unable, this is caused by the coagulation of cold and summer-heat, resulting in unbearable abdominal colic, commonly known as "Intestinal Twisting Miasma." Treatment requires distinguishing between cold and heat. If there is irritability, thirst, and excessive drinking, it is a heat pattern, primarily treated with Guiling Ganlu Yin (Cinnamon Twig, Poria, and Sweet Dew Infusion). If there are cold extremities and no thirst, Lizhong Tang (Regulate the Middle Decoction) is decocted and administered.
