[Main Structure and Performance]:
Absorbable gauze of oxidized regenerated cellulose (hereafter called Gauze) is made from regenerated cellulose as raw material, which is oxidized and woven in to gauze, and will degrade in the body without residual material. The main ingredient is carboxy-methyI cellulose. It is white with a pale yellow fabric and has a faint, caramellike aroma. This product is applied to the surface of the wound, with hemostatic efficacy. The product is shaped by a layer of medical packaging paper, sealed in an aluminum plastic bag, and then packed in a paper plastic bag.
[Dosage and Methods of Application]:
Check the integrity of sterile container, do not use if the package is broken. Remove the gauze from the aluminum-plastic bag, cut out a suitable and minimal size, place the cutted gauze on the hemostatic site and press firmly until hemostasis. The quantity is determined according to the bleeding site and the amount of bleeding. It has been reported that the gauze can be used in the following areas of surgery(except neurosurgery, ophthalmology, and urology): appendectomy, breast surgery, hernioplasty, gastric resection, operations to the throat and nose, liver and gall bladder operations, gynaecological operations, thyroid operations, treatment of superficial injuries, and so on.
1.Do not use if the package is broken.
2.Do not remove the Gauze before bleeding completely stops.
3.Since absorption of the product could be prevented in chemically cauterized areas, its use should not be preceded by application of silver nitrate or any other escharotic chemicals.
4.Precautions should be taken in otorhinolaryngologic surgery to assure that none of the material is aspirated by the patient.
5.Use of this product near large and medium blood vessels may result in vascular embolism.
6.This product can promote blood coagulation at the site of use. Excessive use of this product may cause thrombosis at the site of use.
1.Sterile, for single use, recycle not permitted.
2.This product is a supporting material to conventional haemostasis methods; it cannot replace suture and ligature, etc.
3.Applying the Gauze in a contaminated wound without drainage may lead to complications. lt should be avoided.
4.This product has excellent water absorption, keep away from liquids before using.
5.This product has a low pH; do not mix/use with enzyme based hemostatic agents.
6.Remove any excess after haemostasis is achieved in order to minimize the possibility of foreign body reaction.
7.This product must not be used in conjunction with a blood recovery system, as product fragments may pass through the filter causing blockages in the blood recovery system or the patient's vasculature.
8.The product must not be used in conjunction with a methyl methacrylate adhesive for prosthetic orthopedic devices, which may reduce the strength of the adhesive.
1.The Gauze should not be used in bone defects.
2.The Gauze should not be in stuffing, unless it is to be removed after haemostasis is achieved.
3.The Gauze should not be used to control haemorrhage from large arteries.
4.The Gauze should not be used on non-haemorrhagic serous oozing surfaces, since body fluids are different from whole blood.
5.The Gauze should not be used in neurosurgery, ophthalmology, and urology.
6.The Gauze should not be used to patients allergic to viscose filaments.
1.lt has been reported that the use of oxidized regenerated cellulose products may cause fluid cysts or foreign body reactions.
2.lt has been reported occasionally that the use of oxidized regenerated cellulose products may cause “burning" and "stinging" sensations, or sneezing symptoms after nasal surgery, which may be attributed to the low pH of the products.
3.lt has been reported that use of oxidized regenerated cellulose products may prolongate drainage time in cholecystectomies.
4.lt also has been reported that the use of oxidized regenerated cellulose products may cause stinging" sensations when the products was applied on surface wounds (varicose ulcerations and donor sites).
lf the above symptoms last three days and have no release, please search a medical support immediately.
Method of sterilization is electron beam radiation.
lt should be stored in clean, dry, ventilated and non-corrosive environment, and the temperature should be no more than 20℃.
As a supporting hemostatic device, this product is suitable for various surgical procedures. lt can help control the bleeding of capillaries, veins and small arteries where bleeding can't be well controlled by traditional methods like ligation.
