IMMOBILIZATION PRINCIPLES

A

Motion distortion is one of the most significant contributing factors to unacceptable image quality.

Positioning inaccuracies also contribute to suboptimum image quality.

Motion distortion can result from involuntary and voluntary patient position

Communication with the patient is critical to effective immobilization.

Use the shortest exposure time possible.

Use immobilization aids when possible.

Empathy with the patient’s condition can be effective in facilitating good immobilization.

Q

COMMUNICATION

A

The most effective means of reducing motion and ensuring that the patient cooperates during X-ray procedures is communication.

The technologist needs to give the patient instructions in simple terms that the patient understands.

Communication is not limited to verbal instructions. Patients respond well to demonstrations and other methods of communication.

Q

RESTRAINT

A

Restraining requires a physician’s order and is usually done to prevent them from injuring themselves.

Restraints for adults are usually applied before the patient arrives in the radiology department and may consist of wrist and ankle bands fastened to the bed or stretcher.

Immobilization and restraint devices must never interfere with the patient’s circulation or respiration.

31
Q

Non-Routine Situations

A

Trauma Application

Usually, immobilization devices have already been applied before the patient arrives in the Radiology Department.

Radiographers never remove immobilization devices that have applied by emergency medical personnel (EMT’s) such as traction and cervical collars.

After the Radiologist reads the initial radiographs as negative or approval has been given by the attending physician the immobilization devices may be removed by the physician.

The Radiographer must know which devices are radiolucent vs. radiopaque.

It may be necessary to take the radiographs with radiopaque immobilization devices in place (which will produce artifacts on the films) rather than remove them and cause possible further injury to the patient.

If removed, immobilization devices should be removed slowly with the necessary assistance, sponges and padding may be used to ensure patient comfort.

32
Q

Non-Routine Situations

A

Spinal Trauma
Includes traction devices (i.e., backboards) and cervical collars.

All AP spine views from head to toe may be done without removing the patient from a radiolucent backboard by placing the cassette under the backboard.

A backboard may be used to keep the spine immobilized and support the body.
Most backboards are made of radiolucent materials (i.e. wood, plastic).

Backboards also facilitate easy transfer of the patient from the cart to the table.

To R/O a Cervical spine Fx a Cross-table Lateral view of the Cervical Spine is always done first. If the lateral view is questionable, additional views of the C-spine may be taken with the collar on.

A Radiographer NEVER removes a cervical collar or moves a patient from a backboard (Trauma board) until after the Radiologist has cleared the patient and R/O a spinal fracture.

33
Q

HEAD TRAUMA- NON ROUTINE SITUATIONS

A

Head Trauma

Often cervical collars are in place are in place during radiographic skull examinations.
Since movement of the skull is restricted due to the immobilization of the collar, the equipment must be manipulated (i.e., move the tube and equipment without turning the patient).

With head trauma, bleeding may be evident from the nose or ears of patients with severe head traumas.

34
Q

Extremity Trauma

A

Extremity Trauma

Traction devices may be present on extremities (i.e., traction and air splints).

Traction splints are not always radiolucent.
An anti-shock garment may be present in cases of trauma to the abdomen, pelvis and lower extremities to slow the rate of hemorrhage.

Anti-shock garments are always radiolucent.

35
Q

Pediatric Applications- Non-Routine

A

Pediatric Applications

Good communication between the radiographer and the patient is always important regardless of age.

Use terminology the child will understand.
Trust and security must be established.

Departmental policy should be observed in allowing parents in the room and should be decided on an individual case basis.

The reasons for using immobilization devices should be explained to parents.

Never let a child think that immobilization is being used as a form of punishment.

Effective communication techniques and development of a rapport with the patient

Kindness, patience, honesty, and understanding conveyed to children on their level

Threats and force must be always avoided, and restraints applied gently.

Work with parents.

Follow department policies and procedures.

36
Q

Infant Sheet Restraints

A

Mummification
Effective, simple, inexpensive, and reliable method of restraining or immobilizing a child.
Consists of gently wrapping the small child in a sheet which limits motion.

37
Q

Commercial Restraints for babies

A

Commercial Restraints
1. Upright Restraints (Pig-o-stat, Pedia-Poser)
Allows the child to be rotated 360 degrees in the upright position.
Extremely useful for taking CXR and ABX in an upright position

Commercial Restraints
2. Restraint Boards (Circumcision Board, Brat Board, Octastop Board)

Allows for rotation of the child in the recumbent position.
Radiographs may be obtained in a variety of recumbent positions such as AP, Oblique, and Laterals.

38
Q

Stockinette

A

Stretchable cotton fabric in the shape of a sleeve pulled over a fractured extremity before a plaster cast is applied
Effective as a restraint when pulled over the upper or lower extremities of a child and secured with tape
Good for immobilizing the upper limbs above and behind the child’s head

39
Q

Special Applications of Immobilization

A

Non Routine:
Geriatric Applications

Aging involves the loss of a sense of mobility and sense of balance.

Special care should be taken to make the patient feel secure.

Often geriatric patients are frail and special attention should be given to elderly patients.

Blankets should be used to keep the patient warm.

Radiolucent table pads and pillows should be used for comfort.

A sponge placed beneath the knees reduces back strain.

40
Q

What are key communication skills for radiographers?

A

Demonstrating empathy, fulfilling patient needs, directing patient actions, and obtaining cooperation.

41
Q

What should radiographers do in trauma situations?

A

Never remove immobilization devices applied by emergency medical personnel.

42
Q

What is the procedure for taking radiographs with radiopaque immobilization devices?

A

It may be necessary to take radiographs with devices in place rather than remove them and risk further injury.

43
Q

What is the purpose of a backboard in spinal trauma?

A

To keep the spine immobilized and support the body.

44
Q

What must be done before removing a cervical collar?

A

The patient must be cleared by the Radiologist.

45
Q

What is the procedure for a cross-table lateral cervical spine view?

A

The patient remains supine and immobilized, with the x-ray tube lowered and turned for a horizontal CR.

46
Q

What should be considered when dealing with head trauma?

A

Movement of the skull is restricted, and the equipment must be manipulated without turning the patient.

47
Q

What should be done for pediatric applications?

A

Use terminology the child will understand and establish trust and security.

48
Q

What is sheet restraint?

A

Mummification, which gently wraps a small child in a sheet to limit motion.

49
Q

What are some commercial restraints for pediatric patients?

A

Upright restraints (pig-o-stat) and restraint boards (Circumcision Board, Brat Board, Octastop Board).

50
Q

What should be done for geriatric patients?

A

Special care should be taken to make them feel secure, and blankets should be used to keep them warm.

51
Q

What are some special tips for immobilizing patients?

A

Always explain to your patient, ensure immobilization is not too tight, and seek first aid if harm occurs.

52
Q

Special Tips Immobilizing Patients

A

Always explain and talk to your patient.
Never cause harm by immobilizing.
Make sure immobilization is not too tight.
Immobilize for as short a period as possible.
Never use the sticky side of the adhesive tape directly on the skin.
Never rely on immobilization techniques alone to hold a patient.
If a patient is injured because of an immobilization technique, seek first aid and bring the incident to the supervisor’s attention.
