Saline solution is a safe and multi-use medical method for children, as it is used to moisten the nose and relieve congestion, clean eyes or wounds, and even in special cases to replace fluids intravenously.
At Al Mousa Specialist Hospital, we provide meticulous care for children with thoughtful follow-up of therapeutic doses to ensure the highest levels of safety and effectiveness.
What is the amount of saline solution for children?
The amount of saline solution for children means the appropriate dose of saline solution that is given to the child, whether through instillation, spray, inhalation, or inhalation.
What is meant here is not a fixed number for everyone, but rather a safe dose that takes into account the child’s age and health condition, and its goal is to improve breathing, moisturize the nose, prevent complications, and replace fluids to keep the body from dehydration.
An illustrative table of the amount of saline solution according to the age of the child
The table shows the amount of saline solution for children by age and use.
| the age | To moisturize the nose | Eye wash | Cleaning wounds | Fluid replacement (intravenous) |
| Newborns (0-1 month) | 1-2 drops in each nostril as needed | 1-2 drops | 5-10 ml | Precisely determined by the doctor (usually 20-25 ml/kg) |
| Infants (1-12 months) | 2-3 drops in each nostril up to 3 times daily | 2-3 drops | 10-20 ml | 20-25 ml/kg |
| Young children (1-3 years) | A pinch or 2-3 drops in each nostril up to 3 times daily | 2-4 drops | 20-30 ml | 20-30 ml/kg |
| Older children (4-12 years old) | 1-2 sprays or 3-4 drops per nostril up to 3 times daily | 3-5 drops | 30-50 ml | 20-30 ml/kg |
How to calculate the dose of saline solution for children in cases of dehydration
In cases of dehydration in children, the amount of saline solution for children and its intravenous dose (Normal Saline 0.9%) are calculated accurately according to the child’s weight and the severity of dehydration, and most medical protocols depend on the following criteria:
In cases of severe dehydration or shock (Emergency Fluid Bolus)
In this serious condition, the child needs rapid fluid replacement to save his life.
- The dose of saline solution is: 20 ml per kilogram of the child’s weight.
- It is given over 15-30 minutes, and can be repeated if necessary under medical supervision.
- The dose can be repeated if the child's condition does not improve, and this must be done under close medical supervision.
In cases of moderate drought
In this case, the child is not in shock, but suffers from a noticeable loss of fluid.
- Fluids are replaced over 4 hours.
- The quantity depends on daily maintenance needs as well as the amount of compensation for loss.
Daily maintenance needs
The volume of fluids that the child needs per day is calculated using the Holiday-Segar equation. This method determines the amount of saline solution for children according to weight. This amount is distributed throughout the day:
- The first 10 kg of weight, the child needs 100 ml per kilogram.
- Up to 20 kg, 50 ml is needed for each additional kg.
- And then 20 ml per kilogram above this weight.

Does the amount of saline solution vary depending on the type of use?
Yes, the amount of saline solution for children varies greatly depending on the type of use and therapeutic purpose;
- Use in the nose (drops or spray): The goal here is to moisten the mucous membranes and clean the nasal passages of mucus or dust.
- Use to treat dehydration (oral or intravenous): The goal is to replace fluids and salts lost from the body as a result of vomiting, diarrhea, or excessive sweating.
- Intravenous use: The medical goal is more precise, such as restoring the balance of salts and minerals in the blood or raising blood pressure when severely dehydrated.
So the difference is due to the therapeutic purpose determining the extent of the need for saline solution.
The difference between oral and intravenous saline and the amount of each for children
The difference between them is clear in terms of composition, method of administration, therapeutic goal, as well as the quantity used:
Oral Rehydration Solution – ORS
Objective: To replace fluids and salts lost due to mild to moderate diarrhea or vomiting.
Composition: A mixture of water, sodium, potassium, and glucose, at a studied concentration that helps absorption from the intestine.
Method of administration: Drink or give with a spoon or oral syringe (without a needle) in small increments to avoid vomiting.
Amount of saline solution for children:
- Children under 2 years: about 50-100 ml per kilogram of weight within 4 hours.
- Children from 2 to 10 years: about 50 ml per kilogram of weight within 4 hours.
- Children older than 10 years: Amount as needed until dehydration resolves, usually 2-3 liters per day, with monitoring.
Intravenous saline solution (Normal Saline 0.9%)
Purpose: Used to rapidly replace fluids in cases of severe dehydration, bleeding, shock, or before and during surgical procedures.
Composition: Water with 0.9% sodium chloride, sterile and administered directly into a vein.
Method of administration: It is given through an intravenous catheter in the hospital under medical supervision.
Quantity for children:
- In emergency situations: initial dose of 20 ml per kilogram of weight, given over 15-30 minutes.
- Daily maintenance needs: Calculated according to the “Holiday and Cigar” formula.

What are the best types of saline solution for children?
The best types of saline solution for children depend on the purpose of use, and it is usually preferable to choose the appropriate type based on the child’s age and health condition:
-
Oral Rehydration Solution – ORS
Purpose: This type is designed to compensate for the loss of fluids and salts due to diarrhea, vomiting, or excessive sweating.
Best types:
- ORS is formulated by the World Health Organization, because it guarantees the ideal proportions of salts and sugars.
- Other products for kids come in nice flavors to encourage them to drink.
It should be given in small, frequent doses to avoid vomiting, and it should not be used as a substitute for water in normal cases, but only when dehydrated.
-
Nasal saline solution
Purpose: It is used to moisturize the mucous membranes inside the nose, as it relieves congestion and helps get rid of accumulated mucus resulting from colds, allergies, or dry air.
Best types:
- Sterile and preservative-free products.
- She chooses 0.9% Normal Saline concentrations for infants and children because they are safe and gentle on the nose.
It can be used daily when needed, and does not cause addiction or harm, unlike some medicated nasal drops.
-
Ocular saline solution
Purpose: Cleaning the eyes of dust and pollutants, and moisturizing them in cases of dryness or allergies.
Best types:
- Sterile 0.9% sodium chloride ophthalmic solution intended for ophthalmic use only.
You must ensure that the package is intended for the eye, and do not use nasal or intravenous saline solution on the eye to avoid contamination or irritation.
-
Intravenous saline solution
Purpose: To replace fluids and salts in cases of severe dehydration, during operations, or in cases of shock and blood loss.
Best types:
- Normal Saline 0.9% or Lactate Ringer's solution depending on the medical condition.
This type is only given in hospitals or under strict medical supervision, as the amount of saline solution for children is carefully calculated according to the child’s weight and the severity of his condition to avoid complications such as fluid overload or salt disturbance.
FAQs
How many times can saline solution be used to clean a child's nose daily?
May be used 2 to 4 times daily for normal conditions, such as moisturizing or relieving mild congestion.
Can saline solution be given at home without consulting a doctor?
Yes, saline solution can be given to children at home without consulting a doctor in simple cases such as moistening the nose, relieving congestion resulting from the common cold, or clearing nasal secretions.
In conclusion, the appropriate amount of saline solution for children is an essential step to ensure that it is used safely and without complications, whether for nasal, oral, or intravenous use.
