Care of orthopedic patients: First of all, it includes the care of the fracture site. If the fracture site is treated in a conservative way, the elasticity of the cast should be observed, as too loose a cast can easily lead to fracture displacement, and too tight a cast can lead to ischemia and necrosis of the extremity, and the local condition should be observed. Patients undergoing surgery need to observe the condition of the operated area and the blood flow of the extremity. Excessive swelling can lead to ischemia and necrosis of the extremity, and poor peripheral blood circulation is considered as a possible cause of local swelling. Second, routine care of vital signs and skin care, for example, patients who are bedridden for a long time may have decubitus ulcers and should be observed for skin breakdown or formation of decubitus ulcers at the place of pressure. Finally, other care is included, such as care of the perineum and sacrococcygeal area, because bed rest can lead to the possibility of decubitus ulcers on the skin in the perineal area, which can be extremely difficult to treat if they occur.
