How to Make Saline Solution for Wounds

Irrigating a wound with saline solution creates a perfect environment in which a wound can heal optimally. Cleaning a wound with saline solution is necessary in removing dirt, debris and tissue from the area. Once the wound is cleaned, it is easier for a clinician to examine the wound and start a treatment plan. Saline water is water that contains a high concentration of dissolved salts. The reason for this is because salt removes moisture from the infected or wounded area, in turn clearing away any bacteria or fungi previously present. Saline water is safe and sterile and does not cause any allergies or side effects.

Saline solution is a perfect disinfectant which we recommend always having in your home in case of emergencies. For this reason, in this oneHOWTO article we will tell you how to make saline solution for wounds at home.

Materials to make saline solution

The easiest and most common way of making saline solution is to simply mix table salt and water. At certain times, it is sufficient to make a freshly mixed saline solution, but at other times, you need to sterilize it in order to prevent any infection. The purpose of the solution is important in determining whether you need to sterilize it or not. For example, if you are making the solution to rinse your mouth and teeth, it is adequate to simply warm up some water with dissolved table salt. However, if you need to use this solution to clean a wound, is is important to make a sterile solution only using pure ingredients. Here are the two ingredients required:

  • Water: Instead of ordinary water from the tap, prefer using distilled water, or purified water.
  • Salt: You can use salt that you would normally find in a grocery store. However, we recommend using non-iodized salt, free from iodine. Never use sea salt or rock salt, since they contain chemicals that may worsen the condition. Do not buy flavored, scented or colored salts, and make sure that they do not contain any preservatives.

We suggest using 9 grams of salt per liter of water.

How to make saline solution

If you making a saline solution as a mouth rinse, warm a glass of water and dissolve a teaspoon of salt in it. If you want, you can also add a teaspoon of baking soda into the mixture. Baking soda works to balance the levels of acid in a persons mouth and saliva, and can therefore aid in the disinfecting process.

To make sterile saline solution for wounds, dissolve 9 grams of salt into a liter of boiling water and then cover it with a lid, in order to keep it sterile. The lid will deter any microorganisms from entering into the liquid. Here are step by step instructions:

  • Wash your hands.
  • Fill a stock pot with one liter of distilled water. Boil the water and let it boil for 5 minutes.
  • Pour salt into it and stir with a spoon until all the salt is well dissolved.
  • Carefully pour this solution into a storage container and secure it with a lid. Make sure that you store the container in a dark, clean and cool place to prevent any bacterial growth.

Always store the sterile solution in a sterile container. Write the date on the container, and discard it if you don’t use it within a week of the day you made it. This solution can be successfully used to treat wounds or new piercings. Do not contaminate the solution. Once the solution container is opened, chances of contamination increase.

Additional Tips to Care for Wounds

In order to keep your wound infection-free, and help it heal as fast as possible, you need to keep it clean to prevent any entrance of bacteria. If you have an open wound, you need to apply an antibiotic cream before covering it with a gauze. If it is a closed skin wound, then you can soften it by applying petroleum jelly.

Eat a protein rich diet in order to accelerate the healing process. Bodies use proteins to boost immunity, create antibodies, and reduce inflammation, which helps in the wound healing. Lack of protein can actually enhance the risk of developing an infection. In addition, increase your mineral and vitamin intake:

  • Vitamin B1 can help in building of collagen.
  • Vitamin A increases the strength of scar tissue so that it doesn’t tear.
  • Vitamin C increases elastin in the skin.
  • Vitamin E and B5 accelerate recovery.

Diabetics suffering from wound damage need to keep their blood sugar levels low. Depending on whether you are suffering from type 1 or 2 diabetes, high blood sugar can have an incredibly dangerous impact on your wound and its healing process. If you are suffering from a wound and are already suffering from diabetes, we suggest consulting your doctor as soon as possible.

What is the percentage of this solution and can it be used in a nebulizer? Great article.
We no longer have access to Gentamicin 0.9% Sodium Chloride rinse. By prescription, it is very expensive, and has to be filled at a specialty pharmacy. Sterile saline solution is a good substitute, but keep in mind that it is unstable, and will have to be replaced in less than a week. This article gives additional information beyond what most other recipe-type articles out there, so I would rate this one the most helpful!
