How to Make Saline Solution for the Nose, Eyes, Kids, and More

Ever wondered what is the clear solution in the IV? Is injected when you get treated, used to clear your stuffy nose, or the clear solution in which your lens are kept so that they don’t get dry? 

That is a saline solution. In this article, we will learn about saline solutions. You will find the answer to all the whats and how here. 

What Is A Saline Solution?

A saline solution is a mixture of sodium chloride [NaCl] (table salt) and water. The concentration of the salt in the water differs on its usage purpose. This concentration can make this saline solution isotonic or hypertonic.

Type of Saline Solutions

Normal Saline (NS)

It is a solution made up of sodium chloride and water. The 100ml of normal saline consists of 0.9 grams of sodium chloride, and the rest is distilled water. It can be utilized in the following ways:

  • Used in case of dehydration  
  • To handle Hyponatremia, a condition where sodium levels in the body are low
  • Effective to clean wounds without worsening them
  • Used as a carrier to carry concentrated medication that can't be injected directly into the body

Dextrose Normal Saline (DNS)

It is a solution made up of anhydrous dextrose, sodium chloride, and distilled water. The anhydrous dextrose is dehydrated, powdered glucose. The 100ml of DNS contains 5 grams of dextrose and 0.9 grams of sodium chloride, and the rest is distilled water. 

One thing to keep in mind while using DNS is that you should not give it to a diabetic patient. As it contains glucose, it can be harmful to diabetic patients. 

It can be utilized in the following manner: 

  • Used in case of dehydration 
  • Used to tackle Hypoglycemia, a condition when the blood sugar level is lower than the standard levels
  • Used as a maintenance fluid. Maintenance fluid rehydrates the body, provides energy, and balances the electrolytes in the body

Ringer Lactate (RL)

It is not a type of saline solution, but the major component of this IV fluid is sodium chloride. Thus, it is mentioned here. The composition of components in 100 ml of solution: 

  • Lactic acid: 0.24 ml
  • Sodium hydroxide: 0.115 grams 
  • Sodium chloride: 0.60 grams
  • Potassium chloride: 0.04 grams
  • Calcium chloride: 0.027 grams 
  • Rest is distilled water

It is used when there is heavy blood loss, burning injury, and hypotension (low blood pressure).

How To Prepare Normal Saline Solution At Home?

It is a simple process. It requires only two components: water and sodium chloride (salt). Let's learn the process: 

  • Take a Container

You can use any container to keep the saline solution. Make sure the container is clean and sterile. To sterilize the container, keep it in hot water for a few minutes. 

  • Take 2 Cups of Water

The cup size should be normal. 

If you want and have access, use distilled water. Distilled water is the most suggested option. It is available in packed form in a supermarket or ask a medical store near you. If you are using tap water, ensure to boil it on a medium-high flame for about 20 min. It is because normal tap water might contain many microbes that might cause you harm. Thus, always ensure you boil the tap water to purify it a little. Once the water is boiled, let it cool down to room temperature. 

Take this water in a container of your choice. 

  • Add One Teaspoon Of Salt

You can use iodized salt (table salt) or unionized salt (sea salt). It is suggested to not use grainy salt as it might be irritating and hard to mix. 

  • Add Baking Soda

This solution can give you a burning sensation. Thus to avoid this, you should add a little baking powder to the solution. You could add half a teaspoon of baking soda to the solution.

Uses Of Saline Solution

There are many uses for saline solution, whether it is store-bought or homemade. These uses are as mentioned below:

Nasal irrigation helps clear blocked noses and allergic swelling in the nose. It can also be helpful to clean your nasal cavity to drain all the dirt, mucus, microbe, and pollens that your nasal cavity filters from the air.

  • Start with getting them used to the feeling of the saline solution in their nose. You can do this by using a nasal spray or a nasal drop. 
  • You can do this by laying children in a comfortable position. Spray or insert a few drops of the saline solution into the nasal cavity. Tilt their head a little backside so that the saline solution can go a little deeper into the cavity. This will loosen the mucus and make it easy to remove. After a minute or so blow their nose properly and clean it. 
  • Once they get comfortable with this procedure you can perform nasal irrigation with them. 
  • Take them to the sink. Tilt their head down to the sink and slowly pump the saline solution into the nasal cavity. You can use a squeeze bottle, a large syringe, or a neti pot. This solution will come out of their other nasal cavity or mouth. After the irrigation ask them to properly blow their nose and also clean their nose and mouth properly.
