How to use a rectal thermometer
The rectal thermometer is a medical instrument used to measure a person's internal body temperature. This type of thermometer is inserted into the rectum and provides an accurate reading of the body temperature.
Although the use of a rectal thermometer may seem uncomfortable or embarrassing, it is a reliable method for measuring body temperature, especially in young children who cannot accurately communicate their symptoms.
In this article, we will guide you step by step on how to safely and effectively use a rectal thermometer.
Choosing the right thermometer
The choice of a rectal thermometer is important to ensure the accuracy of body temperature measurement. Here are some factors to consider:
Type of thermometer
There are different types of rectal thermometers, including digital and mercury ones. Digital thermometers are easier to read and do not contain toxic substances like mercury, but they may be less accurate than mercury thermometers.
Material of thermometer
Rectal thermometers can be made of different materials such as glass or plastic. Glass thermometers are more fragile but offer greater precision, while plastic thermometers are more durable but may not be as precise.
Length of thermometer
The length of the rectal thermometer is important to ensure proper measurement of body temperature. Typically, a good rectal thermometer should have a length between 7 and 10 centimeters.
- For infants and young children, it is recommended to use a rectal thermometer with a length of about 7 centimeters.
- For adults, it is recommended to use a rectal thermometer with a length of about 10 centimeters.
It is important to choose a rectal thermometer of appropriate length to avoid injury or damage to the rectum during body temperature measurement.
Ease of use
A good rectal thermometer should be easy to use and read, especially if it is used for infants or young children. Digital thermometers are usually easier to use than mercury thermometers, which require more attention in reading the temperature.
In summary, when choosing a rectal thermometer, it is important to consider the type of thermometer, material, length, and ease of use. Choosing the right thermometer can ensure proper measurement of body temperature and prevent any injury or damage to the rectum.
Preparing the thermometer
Before using the rectal thermometer, it is important to prepare it properly to ensure maximum hygiene and accuracy in measuring body temperature.
Cleaning the thermometer
Start by cleaning the thermometer with warm water and mild soap. Make sure to remove any residue or traces of dirt from the instrument. Then rinse the thermometer well with running water and dry it thoroughly with a soft, clean cloth.
Sterilization of the thermometer
After cleaning the thermometer, it is important to sterilize it to avoid any risk of infection or contamination. There are several ways to sterilize a rectal thermometer:
- Using isopropyl alcohol: Immerse the thermometer in a solution of 70% isopropyl alcohol for about one minute. Remove the thermometer from the solution and let it dry completely before use.
- Boiling: Put the thermometer in a pot of cold water and bring it to a boil. Let the water boil for about 10 minutes, then remove the thermometer from the water and let it dry completely before use.
- Using disinfectants: Follow the manufacturer's instructions to use a specific disinfectant for rectal thermometers. Be sure to rinse the thermometer thoroughly with running water and let it dry completely before use.
In any case, it is important to carefully follow the instructions for sterilizing the thermometer and ensure that it is completely dry before use.
Placing the rectal thermometer
Before starting, it is important to wash your hands and thoroughly clean the thermometer with soap and water or alcohol. Make sure that the thermometer is at room temperature before using it.
Step 1: Preparation
Put some lubricant on the tip of the thermometer to facilitate insertion into the rectum. You can use a water-based lubricating cream or vaseline. Avoid using oil-based or greasy lubricants as they can damage the thermometer.
Step 2: Position
Lie on your left side with your knees bent towards your chest. Alternatively, you can lie on your back with your knees bent and feet resting on the ground. Gently insert the tip of the thermometer into the rectum, pushing it slightly until you feel resistance. The thermometer should be inserted about 2-3 centimeters inside the rectum.
Step 3: Taking the temperature
Hold the thermometer steady for about three minutes or until you hear an audible signal, if your thermometer is equipped with one. If you are using a digital thermometer, wait for the reading to stabilize and then gently remove the thermometer from the rectum. Read the temperature displayed on the thermometer's display.
Remember to thoroughly clean the thermometer after use and store it in a safe and dry place.
Reading the temperature and cleaning the thermometer
After inserting the rectal thermometer, wait for the time recommended by the manufacturer to obtain an accurate reading. Usually it takes about 1-2 minutes. During this period, try to remain calm and relaxed to avoid influencing the reading.
Once the necessary time has elapsed, gently remove the thermometer and read the temperature indicated on the display. If you have difficulty seeing the numbers, bring the thermometer closer to light or use glasses if needed.
After reading the temperature, clean the thermometer thoroughly with warm water and mild soap. Make sure to remove any bodily residue to keep the thermometer clean and hygienic for future use.
- Rinse the thermometer well under running water.
- Gently dry with a soft cloth or let it air dry.
- If necessary, you can also disinfect the thermometer with 70% isopropyl alcohol before storing it.
Always remember to follow the manufacturer's instructions for cleaning your specific type of rectal thermometer. Proper cleaning is essential to prevent the spread of bacteria and diseases.
Conclusion
Now that you know how to use a rectal thermometer, you can monitor your body temperature accurately and reliably. Remember to always use a clean and hygienic thermometer to avoid the spread of bacteria and diseases. If in doubt or if you have any problems, do not hesitate to consult your trusted doctor.
