Risk for vascular compromise, muscle spasms - Anticipate skeletal traction for **[Complications of Fractures]** - Early complications - Hypovolemic shock - Fat embolism - Compartment syndrome - VTE (DVT, PE) - Delayed complications - Delayed union, malunion, and nonunion - Failure to reach proper healing by 6 months - Avascular necrosis of bone - Bone tissue dies - Complex regional pain syndrome (CRPS) - Chronic condition that affects limb after injury - Heterotopic ossification - New bone grows in unexpected areas - Secondary - Pressure ulcers - Disuse syndrome **[Fat Embolism]** - Fat globule moves into the bloodstream after fracture of long bone, pelvis, crush injury, or orthopedic surgery - **DANGEROUS -- CAN BE FATAL** - Nurse should assess for: - Classical manifestations: **hypoxemia, neurologic compromise, petechial rash** - First symptoms: tachypnea, dyspnea, tachycardia, hypoxia, chest pain - Interventions - Notify the provider immediately - Call RR or code depending on LOC **[Amputations]** - May be congenital or traumatic, or caused by conditions - Progressive peripheral vascular disease, infection, or malignant tumor - Used to relieve symptoms, improve function, and improve quality of life - The health care team needs to communicate a positive attitude to facilitate acceptance and participation in rehabilitation **[Amputation: Assessment]** - Neurovascular status and function of affected extremity or residual limb and of unaffected extremity - Signs and symptoms of infection - Nutritional status - Concurrent health problems - Psychological status and coping **[Amputation: Nursing Diagnosis]** - Acute pain - Impaired skin integrity - Disturbed body image - Grieving - Self-care deficit - Impaired physical mobility **[Amputation: Planning/Implementation]** - Major goals include: - Relief of pain - Absence of altered sensory perceptions - Wound healing - Acceptance of altered body image - Resolution of grieving processes - Restoration of physical mobility - Absence of complications - Relief of pain - Administer analgesic or other medications as prescribed - Changing position - Alternative methods of pain relief: mirror box therapy, distraction, TENS unit - Promoting wound healing - Handle limb gently - Residual limb shaping (compression stocking, conditioning, prone positioning) - Prone positioning to prevent flexion contractures in residual limb - Evaluation - Pain relief - Understanding of education - Readiness to participate in self-care **[Amputation: Complications]** - Phantom limb pain - Postoperative hemorrhage - Infection - Skin breakdown - Joint contracture - Happens from positioning and protective flexion withdrawal patterns that occur due to pain and muscle imbalance as result of amputation **[Amputation: Rehabilitation Needs]** - Psychological support - Set realistic goals - Encourage acceptance - Prostheses fitting and use - Physical therapy - Vocational or occupational training and counseling - Use a multidisciplinary team approach -
