Amputation Care

The nurse managing amputation patients coordinates comprehensive post-operative care, wound management, pain control, and rehabilitation initiation. Understanding amputation level selection is crucial for patient advocacy: the goal is to preserve the most distal functional level with adequate healing potential. For diabetic/vascular amputations, healing potential is assessed by transcutaneous oxygen pressure (TcPO2): above 40 mmHg suggests adequate healing; 20-40 mmHg is borderline (50% healing rate); below 20 mmHg has poor healing prognosis and higher-level amputation may be needed. BKA preserves the knee joint, enabling 40% less energy expenditure during ambulation compared to AKA; BKA patients have 70-80% prosthetic ambulation rates compared to 30-50% for AKA. Post-operative wound management includes rigid or soft dressings. Rigid dressings (immediate post-operative prosthesis or IPOP) provide wound protection, edema control, and early weight bearing. Soft dressings with elastic compression bandages require more nursing expertise for proper application but are more commonly used. The residual limb must be shaped conically for prosthetic fitting through compression wrapping. Wound complications include dehiscence (most common), infection, hematoma, and necrosis (indicating inadequate perfusion at the amputation level). The nurse also manages the complex pain syndromes: residual limb pain (nociceptive pain at the surgical site), phantom limb pain (neuropathic pain perceived in the missing portion), and phantom limb sensation (non-painful awareness of the absent part). Each requires different management strategies.
