Preoperative management focuses on relieving anxiety, reducing pain, increasing mobility, and maintaining good nutrition and health through evaluation of body systems. Postoperative management monitors for complications like hemorrhage and infection, promotes acceptance of changes, controls pain, and supports physical recovery and independent living. Amputation is performed at the lowest possible level that will heal, based on circulation and functional usefulness. Common nursing diagnoses for patients include acute pain, risk of phantom limb sensations, skin issues from surgery, changes to body image and coping, and deficits in self-care and mobility due to limb loss.
