Abstract

The invention belongs to the technical field of medicine and particularly relates to a medicinal preparation for preventing operative bleeding and a preparation method thereof. The medicinal preparation is prepared from active ingredients etamsylate, sodium metabisulfite, sodium calcium edetate, methylparaben, a pH regulator and water for injection. The phenomenon that bubbles are produced in the filling process of etamsylate injections is avoided, the problem of product yield reduction caused by bubbles is solved, the safety of the injection in clinical application is greatly improved, and the medicinal preparation is simple and easy to operate and facilitates large-scale production.

Description

technical field

[0001] The invention belongs to the technical field of medicine, and in particular relates to a pharmaceutical preparation for preventing operation bleeding and a preparation method thereof. Background technique

[0002] Postoperative bleeding can occur in surgical incisions, hollow organs, and body cavities. Bleeding after surgery includes primary bleeding and secondary bleeding. Primary bleeding generally occurs within 24 hours after surgery. Hemostasis during surgery is not complete and perfect, such as loose sutures for ligating blood vessels; The coverage of spasms and blood clots temporarily stops wound bleeding and some bleeding points are missed. These are the main reasons for primary bleeding. However, due to factors such as infection and digestive juice extravasation in the later stage of the operation, part of the blood vessel wall is necrotic and ruptured, leading to postoperative hemorrhage, which is called secondary hemorrhage.
