Preparation method of gelatin sponge suspension for hemostasis in neurosurgery operation

Abstract

The invention discloses a preparation method of a gelatin sponge suspension for hemostasis in neurosurgery operation. The method comprises the following steps: firstly, shearing absorbent gelatin sponge into pieces by using scissors; placing the obtained gelatin sponge pieces into a 20ml syringe; taking another 20ml syringe; drawing 5ml of physiological saline; connecting the gelatin sponge pieceswith the 5ml of physiological saline at right angles through a three-way cock; and repeatedly mixing the contents of the two syringes to obtain the gelatin sponge suspension. The gelatin sponge suspension prepared by the method has the advantages of good hemostasis effect, high safety, economy, practicality, definite effect, simple preparation, low cost and capability of reducing the economic burden of families and society of patients. The gelatin sponge suspension prepared by the method can be widely applied to hemostasis treatment of central nervous system operations (errhysis of parts suchas bone hole, cancellous bone, cranial bone barrier, epidural part, venous sinus and brain tissue), and is particularly suitable for being used in basic hospitals.

Description

technical field [0001] The invention relates to a preparation method of a hemostat, in particular to a preparation method of a gelatin sponge suspension used in neurosurgery for hemostasis, which is especially suitable for use in primary hospitals. Background technique [0002] Due to the rich blood supply of the nervous system tissue structure, there is more bleeding and oozing in neurosurgery than in general surgery, and it is often impossible to achieve complete hemostasis by relying solely on bipolar electrocoagulation, and there is more bleeding in wounds after neurosurgery. , The neurosurgery operation takes a long time, and the patient's bleeding and oozing for a long time will cause a large amount of coagulation factors in the body to be consumed, resulting in difficulty in hemostasis in the later stage. Therefore, effective prevention of intraoperative hemorrhage and postoperative rebleeding in neurosurgery is of great significance to improve surgical results, espec...

Problems solved by technology

[0004] Gelatin sponge itself has no hemostatic effect, and its volume increases significantly after absorbing blood, which may cause unnecessary compression on nerve tissue and cause nerve dysfunction. There have been reports abroad that the use of gelatin sponge in spinal canal surgery has caused acute postoperative paraplegia In some cases, it is easy to fall off from the bleeding surface, causing the original bleeding site to continue to bleed
