Transcript of Immobilization in Pediatric Radiology

Children reach different levels of cognitive thinking at different ages. The ability varies from child to child at what age they can understand direction. Usually around three or four years old they can be talked through a procedure without parental aid or immobilization devices. The most important part is making the child feel comfortable.
Developing Trust
It is vital for the technologist to develop a sense of trust with the parent and the child. Make sure when first meeting your patient to talk to the parent but also introduce yourself to the child you are radiographing, starting to develop that relationship so they will not be scared. The first impression is very important, you have the opportunity to make imaging fun!
Being Successful in pediatrics
How motion looks in radiographs

This image shows image blur due to patient movement. This is seen by the undefined shapes and lack of focus.
Parents Point of View
Immobilization Importance
Immobilization is used in pediatric radiology to obtain the highest image quality. Immobilizing children is vital in some cases due to the fact that any movement creates blur in the images making reading the radiographs very difficult. Using various equipment and techniques technologist can obtain very high quality radiographs to get a clear diagnosis for the patients.
Immobilization in Pediatric Radiology

Images using immobilization devices
Radiographers Point of View
Radiographers know they must use immobilization techniques to get the best picture possible to provide the most information they can so their patients can get the proper diagnosis. While sometimes holding down a child can look harmful radiographers know it is necessary. Try to make immobilization as fun as possible by really interacting with the children.
-Technologist must show a great attitude
-Have the room set up so the procedure goes quickly
-Make imaging fun!
-Reward with something simple like a sticker for being brave
-Most importantly develop that trust with the patient.

Using sandbags to keep the arms out of the field of view and to prevent rotation helps improve image quality greatly and hows the importance of being still for an x-ray.

Parents can sometime perceive technologist holding down patients for exams as hurting them when the children begin to cry. Parents want to protect their children as much as possible, especially ones who are extremely ill and go through lots of testing. Help parents perceive in a positive manner by getting them involved. Have them participate in the holding to comfort their child as well as save the technologist from unnecessary radiation exposure. Also explain to them thoroughly what you will be doing so no positioning technique or device comes as a shock.
Important things to remember when imaging pediatrics
-Always use shielding when you can to protect from excessive radiation
-Minimal repeats by using proper instruction and proper immobilization techniques
-Use short exposure time techniques to prevent from blurred motion showing up in the radiographs.
Make imaging fun!
-Show the child your big "camera" and show them how it works
-Have the child make a shadow puppet in the light field to show it doesn't hurt
-Put stickers on the camera for them to look at when they are getting their picture taken.
-Entertain the children by singing songs to soothe ones that are scared
Tips and Tricks
When to Immobilize
used for pediatric chest x-rays, perfect for technologist who must work by themself.
Head clamps
These devices are perfect for immobilizing the head for procedures such as skull x-rays. Just place the device on each side of the head to prevent side to side motion.
Another immobilization technique is to wrap the patient in sheets to prevent movement to improve image quality. A new invention has surfaced making the material more dense and has the ability to have it velcro around the patient. An example is shown below of a modern device used to prevent movement.
Tape and bandages
Things around the Radiology Department can be used as immobilization devices. Items such as tape and ace bandages can be used to keep them in the correct position as a guiding tool.
Immobilization with Tape
Holding Techniques
At some facilities you may work at many immobilization devices may not be available. When you are faced with this issue holding techniques will help get the best images. Holding techniques are very helpful when you have a technologist to hold and another technologist to take the exposure.
Positioning with sandbags
Holding Techniques
Plexiglass Paddles
Plexiglass paddles are a great tool to flatten out anatomy by preventing movement and ensuring the technologist is getting the correct projection.
Using Plexiglass Paddles
Positioning sponges can also be utilized as an immobilization tool. Since these are radiolucent you can use them on top of anatomy to prevent movement, or as guides to help pediatric patients get into the correct angle for a picture. These can be used along with tape to be highly effective.
Positioning Sponges
Immobilization Techniques
Using a combination of a variety of these techniques help technologist to obtain high quality images. While some of the devices look intimidating, using them in a correct way helps get a more diagnostic image for patients. Imaging is not meant to be scary so make imaging fun for your patients!
Keeping radiation low
Keeping radiation dose low in children is also very important to consider while imaging. Using immobilization devices will help prevent you from having to expose a patient twice, but there are other things to remember to help protect your patient.
Radiation Protection
All of these things play a huge role in limiting radiation to our patients. This list should be kept in mind every time an examination is complete to ensure our patients safety
-ALARA ( as low as reasonably possible)
-Short Exposure Time
-Limited Views
-Close Collimation
Using the immobilization devices in combination with the radiation protection list will ensure your patients safety as well as ensure they are getting the highest quality of images possible. As a radiologic technologist it is our job to get the best images we can for the radiologist to diagnose the patient. This information was all gathered through interviewing technologist in the field with hands on experience. Through talking to multiple people I present my findings to you through this Prezi. I hope you find very helpful in your career and do not forget to make imaging fun!
