Abstract

The invention relates to surgical anti-adhesion flushing liquid, which belongs to the technical field of medicine. The surgical anti-adhesion flushing liquid is prepared from sodium hyaluronate, medicine water and any one kind of materials of sodium chloride or glycine or glucose or mannite or sorbierite. The surgical anti-adhesion flushing liquid provided by the invention is mainly prepared from the sodium hyaluronate as major effective ingredients, and the surgical anti-adhesion flushing liquid can be used for abdominal adhesion, adhesive ileus and the like after the surgical abdominal operation.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to an anti-adhesion flushing liquid for surgery. Background technique [0002] With the continuous advancement of modern surgical technology, surgical techniques and methods are also developing rapidly. From the founding of the People's Republic of China to the present, the number of surgical operations in my country has shown a rapid growth trend. In the past, many diseases were treated conservatively. Satisfactory results can be achieved in a short period of time. According to statistics, the number of surgeries nationwide in 2005 was close to 10 million, which shows that the technical level of surgeries has been brought into full play. But for many years, in surgical operations, more than 90% will involve the problem of postoperative tissue adhesion. Adhesion is an abnormal structure formed by combining connective tissue fibrous bands with adjacent tissues or organs due to tissue...
