，肢冷脉伏，何以辨其脉之滑数为热，微迟为寒那？虽然，两手六部脉乍不见，而尺中应有一两部未伏，设两手虽伏，

二经动脉中必有两三部不伏，即在此未伏脉中，仔细寻其微迟滑数，以定寒热，若果全身之脉皆伏，其人已气闷而绝矣。
夫暴厥之因实繁，此就寒热而论，然不独寒热当辨，即温暑同为热深之厥，其治有间，而况寒热乎？是不容不辨也。
夏季有人突然晕倒，不省人事，手足逆冷，这称为暑厥，属于阴风（此处指暑邪内闭导致的类似寒证的假象）。此时不可立即使用寒凉药物，应先以辛温药物发散解表，待患者苏醒后，再用辛凉药物清除火邪以除病根。若误用热药及艾灸，会导致立即死亡。灌服童便混合姜汁，也易于使患者苏醒。
霖按：暑厥是由于热邪闭塞诸窍所致，应先以紫金锭用凉水磨服一二钱，待厥逆缓解后，可选用竹叶石膏汤，或黄连香薷饮。夹有湿邪者，用白虎加苍术汤。阴液亏损者，用麦冬汤，或生脉散，根据病情斟酌加减治疗。西瓜、芦根、萝卜、甘蔗等汁液，均为清凉滋润之品，均可服用。
以上论述的是暑厥。若将寒厥误认为热厥，则灾祸立至。然而寒证与热证的辨别，不可不知。凡是四肢逆冷，身体寒冷，面色青紫，蜷缩而卧，手足指甲青暗，腹痛但不口渴，小便清长色白，大便溏泄，脉象微迟的，是阳气衰微于下焦的寒厥。若是四肢厥逆，身体发热，面色红赤，嘴唇干燥，口干，舌苔苦（厚腻），眼睛闭合或不闭合，烦躁口渴，小便短少涩痛，大便燥结，脉象滑数的，是阴液衰微于下焦的热厥。
然而，寒厥也有突然烦躁不安，想要坐在泥水井中的情况，这是阴极发躁的戴阳证，不可当作热证治疗。热厥也有四肢冰冷、脉伏的情况，这是热邪入里，气血不得宣通，所谓“火极似水”，不可当作寒证治疗。突然不省人事，四肢冰冷，脉伏，如何辨别脉象滑数是热证，微迟是寒证呢？虽然如此，两手六部脉象暂时摸不到，但尺部脉中必有一两部未伏；即使两手脉象均伏，十二经动脉中也必有两三部未伏。就在这些未伏的脉象中，仔细探寻其微迟或滑数，以确定寒热。如果果然全身脉象皆伏，那么此人已经气闷而绝症了。
暴厥的原因确实繁多，这里仅就寒热而言，然而不仅寒热应当辨别，即温病和暑病同为热深之厥，治疗方法也有区别，何况是寒热之别呢？这是不容不辨别的。
In summer, if a person suddenly faints, loses consciousness, and has cold extremities, this is termed Shu Jue (Summerheat Collapse), which belongs to Yin Wind (here referring to the false cold syndrome caused by internal closure of summerheat pathogen). Cold-natured medicines should not be used abruptly; instead, acrid-warm medicines should first be used to disperse and resolve the pathogen. After the patient regains consciousness, acrid-cool medicines should then be used to clear fire and eliminate the root cause. Misusing hot medicines or moxibustion will lead to immediate death. Administering child's urine mixed with ginger juice can also facilitate recovery.
Lin notes: Shu Jue (Summerheat Collapse) is caused by heat pathogen blocking the orifices. One should first take one or two qian of Zijin Ding (Purple Gold Pill) ground in cool water. Once the collapse resolves, Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) or Huanglian Xiangru Yin (Coptis and Elsholtzia Drink) may be selected. If accompanied by dampness, Baihu Jia Cangzhu Tang (White Tiger Plus Atractylodes Macrocephala Decoction) is used. For yin deficiency, Maidong Tang (Ophiopogon Decoction) or Shengmai San (Generate the Pulse Powder) is prescribed, with adjustments made according to the condition. Juices from watermelon, reed rhizome, radish, and sugarcane are all cooling and moistening agents that can be consumed.
The above discusses Shu Jue (Summerheat Collapse). If Han Jue (Cold Collapse) is mistaken for heat, disaster will follow swiftly. However, the differentiation between cold and heat must not be ignored. Whenever there are cold extremities, a cold body, cyanotic complexion, curled-up posture, dark blue fingernails and toenails, abdominal pain without thirst, clear and white urine, loose stools, and a faint and slow pulse, it is Han Jue (Cold Collapse) due to yang depletion in the lower jiao. If, however, there are cold extremities, a hot body, flushed face, dry lips, dry mouth, bitter/thick tongue coating, eyes closed or open, restlessness, thirst, scanty and painful urination, dry stool, and a slippery pulse, it is Re Jue (Heat Collapse) due to yin depletion in the lower jiao.
However, Han Jue (Cold Collapse) can also present with sudden restlessness and agitation, where the patient desires to sit in mud or well water; this is Dai Yang Syndrome (Floating Yang Syndrome) caused by extreme yin generating false heat, and it should not be treated as heat. Re Jue (Heat Collapse) can also present with cold limbs and hidden pulse; this is because the heat pathogen has entered the interior, preventing the free flow of qi and blood, known as "extreme fire resembling water," and it should not be treated as cold. How to differentiate whether a hidden pulse indicates heat (slippery and rapid) or cold (faint and slow) when a person suddenly loses consciousness, has cold limbs, and a hidden pulse? Although the pulses at the six positions of both hands may temporarily be imperceptible, there must be one or two positions at the Chi position (cun-kou pulse) that are not hidden; even if the pulses at both hands are hidden, there must be two or three positions among the twelve meridian arteries that are not hidden. Within these non-hidden pulse positions, carefully examine whether they are faint/slow or slippery/rapid to determine cold or heat. If indeed all pulses on the body are hidden, the person has already suffocated and died.
The causes of sudden collapse (Bao Jue) are indeed numerous. Here, we discuss only cold and heat. However, not only must cold and heat be differentiated, but even Wen Bing (Warm Diseases) and Shu Bing (Summerheat Diseases), which are both collapses due to deep heat, have different treatments, let alone cold versus heat. Therefore, differentiation is indispensable.
