2. Tibetan medical treatment
In accordance with the basic medical conditions in Tibet and the special requirements of some patients, Tibetan medicine can be used to treat acute drug poisoning. The main methods include:
(1) Inducing vomiting
For patients with short poisoning time, clear consciousness, and cooperation, forcing them to drink a large amount of warm water (about 500ml) and stimulating the pharynx with fingers to induce vomiting. If the effect is not good, Banbo Soup or Daji Jiajian Soup can be used for gastric lavage and emetic treatment. This method can be repeated, but it should not be used for patients with long poisoning time and severe condition.
(2) Laxative
Generally used as a supplementary detoxification method after inducing vomiting. Taking 3-5 pills of Liu Wei Neng Xiao Wan or adding 1-5g of high mountain rhubarb root powder for laxative effect. This method should be used with caution in patients with weak constitution or a history of gastrointestinal ulcers.
(3) Adjusting medication therapy
Tibetan medicine generally uses a comprehensive treatment approach of clearing, reducing, and eliminating toxins to thoroughly treat poisoning. However, for acute poisoning, detoxifying drugs such as Jinhe Qingdu San, Wangri Jiedu Wan, Shier Wei Shanglu Ka Cai San, and Shisan Wei Honghua Ka Cai San can be directly taken for neutralization and elimination.
(4) Symptomatic treatment
For symptoms such as restlessness, palpitations, shortness of breath, arrhythmia, coma, and weakness during the later stage of treatment, symptomatic treatment can be applied according to the condition.
