Study Notes

Antibiotic Bead Chain Implants

Antibiotics are applied to bone cement and covered with an artificial skin graft to achieve high local dosages, creating a sterile wound.

Removal of Implant or Prosthesis

Removing an implant or prosthesis is an option to treat infection.

Treatment Options

Antibiotics can be administered through irrigation or a PICC line for strong antibiotics.
Hyperbaric O2 chamber increases oxygen to tissue.
Amputation may be necessary if infection does not respond to antibiotics.

Nursing Care

Sterile dressings with normal saline are used, and wet-to-dry dressings are applied.
Heat application and exercise are avoided to prevent spreading the infection.
Good body alignment and frequent position changes are important.
Psychologic support is necessary as wound healing may take a long time.

Prevention

Prophylactic antibiotics are given to patients with implanted prosthetic devices before invasive procedures, including dental work.

Complications

Pathologic fractures and deformity can occur.

Amputation

Terms and Types

Stump: the remaining portion of the amputated limb.
BKA (Below the Knee Amputation): amputation of the leg below the knee.
AKA (Above the Knee Amputation): amputation of the leg above the knee.

Indications for Amputation

Poor blood circulation (PVD)
Gangrene
Traumatic or thermal injury
Malignant tumors
Uncontrolled, widespread infection
Congenital disorders

Diagnostic Studies

WBC count
Arteriography
Doppler (to assess circulation and detect tumors, injuries, etc.)

Nursing Care for Amputation

Assess preexisting illnesses
Preop teaching: explain reasons for surgery, postop expectations, phantom pain, and rehabilitation
Postop care: vital signs, dressings, sterile technique
Rehabilitation: safety, compression bandage, transfers, crutch walking, and prosthesis fitting

Complications of Amputation

Hemorrhage
Infection
Amputation contractures
