Which complication requires immediate attention after a below-knee amputation?

After a below-knee amputation, the most critical complication that requires immediate attention is thromboembolism. The surgical procedure, along with immobility post-operation, increases the risk of blood clots forming in the veins, particularly in the legs. If a clot dislodges, it can travel to the lungs, leading to a pulmonary embolism, which can be life-threatening. Recognizing the signs of thromboembolism—such as sudden chest pain, difficulty breathing, or a rapid heart rate—is crucial for prompt intervention and preventing serious complications.

Other complications, while significant, may not require the same immediate response. Hypovolemic shock, though critical, can often be managed first by addressing fluid replacement and monitoring vital signs. Infection is also a major concern, especially in the surgical site; however, it typically manifests over time rather than abruptly. Wound dehiscence, or the reopening of the surgical site, while still serious, is often not as immediate as thromboembolism and can typically be managed with surgical intervention at a later stage. Therefore, the urgency associated with thromboembolism highlights it as the complication demanding immediate medical attention following a below-knee amputation.
