凡是分娩之后，出现眼花、头晕、意识丧失的情况，称为血晕。其病因主要有三种：一是因过度劳累导致气竭神昏；二是因失血过多导致元气欲绝；三是因痰火乘虚上泛导致神志昏乱不清。患这三种情况，都是因为神魂不能随心神正常运化，呼吸几近停止。此时应紧急服用加味生化汤二三剂，以消除瘀块、缓解疼痛。外用醋韭法刺激鼻腔，让产妇闻到醋的气味，使精神收敛而不散乱。这是救治血晕的紧急方法。一般来说，体质虚弱或临产时，应提前煎好生化汤，并预备韭菜、醋和瓶子以防不测，这才是万全之策。婴儿出生后，不可只顾喜悦而忽视母亲，母亲也不宜顾念孩子而忘记疲劳。另外，产后立即躺卧，或者愤怒导致气机逆乱，都能引起晕厥。务必谨慎！
加味生化汤的组成是：川芎三钱，当归六钱，姜炭四分，桃仁十粒，炙甘草五分，荆芥五分。加水煎煮，加入酒热服。如果出汗多，加人参二钱，黄芪一钱，但必须在没有瘀块疼痛的情况下才使用。如果疼痛剧烈，加肉桂五分；口渴加麦冬一钱，五味子十粒。有痰加竹沥半杯，姜汁一匙。若是痰火乘虚上泛导致的晕厥，加橘红四分。如果两手脉象伏匿或左手脉绝，加人参四钱，麦冬一钱，五味子二钱。对于上述三种血晕，切忌使用破血耗气的药物。即使山楂药性缓和，也不宜服用。如果有瘀块疼痛，可用生化汤送服益母丸及鹿角灰。如果是气脱将绝、牙关紧闭、药物无法下咽的情况，用鹅毛管插入喉咙灌药。如果灌药后身体逐渐回暖，则不拘泥于剂数继续灌服。同时应用温热的手隔着单衣从心口揉至腹部，并时常更换温暖的衣物保暖，自然会逐渐苏醒。如果醒来后瘀块疼痛仍未消除，应减去人参、黄芪，单独服用生化汤，待瘀块消散、疼痛停止后，再进补人参、黄芪。
After delivery, if the patient experiences blurred vision, dizziness, and loss of consciousness, it is termed Blood Syncope (Xue Yun). There are three main causes: first, exhaustion from overwork leading to Qi depletion and spiritual confusion; second, excessive blood loss leading to a critical deficiency of Yuan Qi (Original Qi); third, Phlegm-Fire rising due to deficiency, causing clouded consciousness. In these three conditions, the Hun (Ethereal Soul) fails to accompany the Shen (Spirit) in its normal circulation, resulting in near-respiratory arrest. Immediately administer Jiawei Shenghua Tang (Modified Birth-Tonifying Decoction) for two or three doses to resolve blood stasis and alleviate pain. Externally, use the Vinegar and Chinese Chive method to stimulate the nasal cavity, allowing the parturient to smell vinegar, thereby gathering and stabilizing the Spirit. This is an emergency method for treating Blood Syncope. Generally, for weak parturients or during labor, Shenghua Tang should be prepared in advance, along with Chinese chives, vinegar, and bottles as a precaution. This ensures complete safety. After the infant is born, one must not focus solely on the joy of the child while neglecting the mother, nor should the mother ignore her fatigue due to concern for the child. Furthermore, lying down immediately after birth or experiencing anger leading to rebellious Qi can all induce syncope. Exercise utmost caution!
Jiawei Shenghua Tang (Modified Birth-Tonifying Decoction) consists of: Chuanxiong Rhizome (Chuanxiong) 3 qian, Angelica Sinensis Root (Danggui) 6 qian, Charred Ginger Rhizome (Jiangtan) 4 fen, Peach Kernel (Taoren) 10 grains, Honey-fried Licorice Root (Zhi Gancao) 5 fen, Schizonepeta Spike (Jingjie) 5 fen. Decoct in water, add wine, and take hot. If sweating is excessive, add Ginseng Radix et Rhizoma (Renshen) 2 qian, Astragali Radix (Huangqi) 1 qian; however, this is only indicated when there is no abdominal pain due to stasis. If pain is severe, add Cinnamon Twig (Rougui) 5 fen; if thirsty, add Ophiopogon Tuber (Maidong) 1 qian and Schisandra Fruit (Wuweizi) 10 grains. If phlegm is present, add Bamboo Sap (Zhuli) half cup and Ginger Juice (Jiangzhi) one spoon. If syncope is caused by Phlegm-Fire rising due to deficiency, add Exocarpium Citri Reticulatae (Juhong) 4 fen. If the pulse is hidden in both hands or absent in the left hand, add Ginseng Radix et Rhizoma (Renshen) 4 qian, Ophiopogon Tuber (Maidong) 1 qian, and Schisandra Fruit (Wuweizi) 2 qian. For these three types of Blood Syncope, strictly avoid herbs that break blood and deplete Qi. Even Hawthorn Fruit (Shanzha), despite its mild nature, should not be used. If there is pain due to uterine subinvolution (blood stasis), administer Yi Mu Wan (Motherwort Pill) and Cervus Cornu Pulveratum (Lujiaohui) alongside Shenghua Tang. If Qi collapse is imminent, with clenched jaw and inability to swallow medicine, insert a goose feather tube into the throat to instill the medication. If the body gradually warms up after instillation, continue administration regardless of the number of doses. Simultaneously, use warm hands to massage from the heart region down to the abdomen through a single layer of clothing, and frequently change into warm garments to maintain warmth. The patient will naturally regain consciousness gradually. If, upon waking, the pain from uterine subinvolution persists, reduce the dosage of Ginseng Radix et Rhizoma (Renshen) and Astragali Radix (Huangqi), and take only Shenghua Tang alone. Wait until the stasis resolves and pain ceases before resuming supplementation with Ginseng Radix et Rhizoma (Renshen) and Astragali Radix (Huangqi).
