1, the concentration of physiological saline needed by mammals is 0.9%. Weigh 0.9 g sodium chloride, dissolve it in a small amount of distilled water, and dilute it to 100 ml.

2. The concentration of normal saline needed by birds is 0.75%. Weigh 0.75g of sodium chloride, dissolve it and dilute it with distilled water to 100 ml.

3. The concentration of physiological saline needed by amphibians is 0.65%. Weigh 0.65g of sodium chloride, dissolve it and dilute it with distilled water to 100 ml.

The role of physiological saline:

It can avoid cell rupture, the osmotic pressure is the same as that outside the cell, and it will not dehydrate the cell or absorb excessive water, so it is used more in places where liquid is needed in various medical operations.

Precautions:

1, debridement with normal saline; If chlorhexidine or iodine preparation is used, please rinse it with normal saline.

2. Because the hydrogel contained in Youtuo SSD/ Youtuo will stick to the rubber, it is recommended to soak the surgical gloves or dressing forceps with salt water during dressing change to avoid this situation.

3. Cover the wound directly with Youtuo SSD or Youtuo, which can be cut according to the wound condition, and the edge should exceed the outer edge of the wound by 3 cm to protect the fragile skin around. Please don't use it folded.
