杨士瀛说：慢脾风，是由慢惊风之后，呕吐腹泻损伤了脾脏，病情发展到极点，最终归于虚损之处，只有脾脏受累，所以称为脾风。风邪无法强行驱逐，惊风难以直接治疗，只是脾间痰涎凝滞，虚热往来。如果眼睛闭合，这是脾困气乏、神志昏迷的表现。如果见到眼睛闭合，就是脾风。慢惊风的眼睛在半开半合之间，这说明阴气旺盛，传入脏腑之间，阳气已经亏损。脾经属阴，病邪依次传入脾脏，所以称为慢脾风的证候。慢惊风如果眼睛半开半合，就应当预先按照慢脾风进行调理。慢脾风的证候，表现为面色青、额头出汗、舌短头低、眼睛闭合不睁开、睡中摇头吐舌、频繁呕吐腥臭之物、口噤切牙、手足轻微抽搐而不能收回。或者身体发冷，或者身体温热但四肢冰冷。其脉象沉微，阴气极盛，胃气极虚，十个人中只能救活一两个。这大概是由慢惊风传变而来，宜用黑附汤来救治。又有生附子四君子汤、蝎附散都可以使用。治疗慢脾风用药，是不得已而为之。其危险程度如同灯中没有油，逐渐变得昏暗减弱。钱乙（钱氏）使用金液丹与青州白丸子各半研匀，用米饮薄荷汤送服一钱或一钱半。这是为了截断风阳。
张云岐说：小儿头部虽然发热，但眼珠青白且脚冷；头部虽然发热，或者腹胀且脚冷；头部虽然发热，或者泄泻且脚冷；头部虽然发热，或者呕吐且脚冷；头部虽然发热，或者口渴且脚冷。以上五种症状伴有抽搐的，称为慢脾风。应立即给予补脾益真汤加全蝎一枚，或者使用全蝎观音散。
谭殊圣说：慢脾风，又名虚风。小儿在呕吐或腹泻后，面色虚黄，因虚而发热，刚出现摇头斜视、昏困额头出汗、身体也有粘汗、声音低沉小而焦躁，这就是脾风的症状。不一定非要因为急惊风或慢惊风传变次第而至。慢脾风，只有通过呕吐、腹泻、积滞与痢疾传入才会发生。其症状变化非常快，虚损也更快。治疗必须循序渐进保持平和，没有迅速痊愈的道理。调理脾脏养胃气，不可用药过量。
沈金鳌按语：汤氏的方法，凡是因呕吐腹泻导致虚风慢脾的，先用夺命散、青州白丸子粉末，煎煮成稀糊状，加入蜂蜜调和，控制吐出痰涎后，再服用醒脾散。
Yang Shiying stated: Manpi Feng (Slow Spleen Wind) arises after Man Jing Feng (Slow Convulsion), where vomiting and diarrhea damage the spleen. The disease has progressed to its extreme, ultimately returning to a state of deficiency, affecting only the spleen; hence it is called Spleen Wind. The wind cannot be forcibly expelled, and convulsions are difficult to treat directly. It is merely that phlegm and saliva stagnate within the spleen, with deficient heat fluctuating. If the eyes are closed, it indicates spleen exhaustion, qi deficiency, and spirit confusion. If the eyes are seen closed, it is Manpi Feng. In Man Jing Feng, the eyes remain half-open and half-closed, indicating that yin qi is abundant and has transmitted into the zang organs, while yang qi is already depleted. Since the spleen meridian belongs to yin, the pathogen enters the spleen sequentially; thus, it is termed the syndrome of Manpi Feng. If Man Jing Feng presents with eyes half-open and half-closed, one should preemptively manage it according to Manpi Feng protocols. The manifestations of Manpi Feng include a bluish complexion, sweating on the forehead, a short tongue, drooping head, eyes closed and unable to open, shaking the head and protruding the tongue during sleep, frequent vomiting of foul-smelling substances, locked jaw with teeth grinding, slight twitching of the hands and feet that cannot retract, or cold body temperature, or warm body but cold limbs. The pulse is deep and faint, indicating extreme abundance of yin qi and extreme deficiency of stomach qi. Only one or two out of ten may be saved. This likely results from the transmission of Man Jing Feng; Hei Fu Tang (Black Aconite Decoction) should be used for rescue. Sheng Fuzi Sijunzi Tang (Raw Aconite Four Gentlemen Decoction) and Xie Fu San (Scorpion and Aconite Powder) are also applicable. Medication for Manpi Feng is a last resort. Its critical nature is like a lamp running out of oil, gradually dimming. Qian Yi (Qian Shi) prescribed mixing Jin Ye Dan (Golden Liquid Pill) and Qingzhou Bai Wan Zi (Qingzhou White Pills) in equal parts, ground uniformly, and administered with rice water and mint decoction, one qian or 1.5 qian. This aims to intercept wind-yang.
Zhang Yunqi stated: Although the child's head feels hot, if the eyeballs are blue-white and the feet are cold; although the head feels hot, if there is abdominal distension and cold feet; although the head feels hot, if there is diarrhea and cold feet; although the head feels hot, if there is vomiting and cold feet; although the head feels hot, if there is thirst and cold feet. When any of these five symptoms present with convulsions, it is named Manpi Feng. Immediately administer Bupi Yizhen Tang (Spleen-Supplementing and True-Yang-Replenishing Decoction) with one whole Scorpion (Quanxie), or Quanchi Guanyin San (Whole Scorpion Guanyin Powder).
Tan Shusheng stated: Manpi Feng is also known as Xu Feng (Deficiency Wind). After vomiting or diarrhea, if the child’s complexion is sallow and deficient, and fever arises from deficiency, accompanied by initial signs of head shaking, oblique gazing, drowsiness, forehead sweating, sticky sweat on the body, and a low, small, and anxious voice, this is the syndrome of Spleen Wind. It does not necessarily have to result from the sequential transmission of Ji Jing Feng (Acute Convulsion) or Man Jing Feng. Manpi Feng occurs only through transmission via vomiting, diarrhea, food accumulation, or dysentery. The symptom changes are extremely rapid, and the deficiency progresses even faster. Treatment must follow a gradual and mild approach; there is no principle of rapid cure. Regulate the spleen and nourish the stomach without overdosing.
Shen Jin'ao commented: According to Tang Shi’s method, for cases where vomiting and diarrhea lead to Xu Feng and Manpi, first use Du Ming San (Life-Seizing Powder) and Qingzhou Bai Wan Zi powder, decocted into a thin paste, mixed with honey, to induce expectoration of phlegm. After the phlegm is controlled, administer Xing Pi San (Awaken Spleen Powder).
