Can be complicated with bedsores, limb blood circulation disorders, limb ischemic contraction, and other diseases.
1Bedsores:Also known as bedsores, it is caused by long-term pressure on a local part of the body, which obstructs blood circulation, leading to ischemia of the skin and subcutaneous tissue, and causing blisters, ulcers, or gangrene.
Decubitus ulcers are more common in paraplegic patients. Other diseases also occur. The prone parts are the sacrum, ischial tuberosity, greater trochanter of the femur, etc., followed by the calcaneus, occipital bone, anterior superior iliac spine, medial and lateral malleoli, etc. The formation process is divided into three stages: erythema stage, blister stage, and ulcer stage.
2Ischemic contraction:Rare, but once it occurs, it can cause serious consequences. Therefore, it is a serious complication of limb trauma. Severe displacement fractures, large hematomas, tight casts or splints can all cause this condition. After the limb is injured, due to the injury or mechanical compression of the brachial artery, the artery and collateral circulation occur spasm. The spasm causes severe obstruction of blood circulation in the lower limb, leading to the occurrence of this condition. Symptoms of ischemia in the distal part of the limb, such as severe pain, swelling, changes in skin color, weak or inability to move fingers (toes), dullness of sensation, weakened or disappeared pulse, etc., whether passive movement of the fingers (toes) causes pain. Difficulty in breathing, patients often wake up from deep sleep with a feeling of suffocation, have to sit up, cough frequently, and appear severe difficulty in breathing; cough and hemoptysis; may have fatigue, insomnia, palpitations, etc. The upper abdomen is full, often accompanied by loss of appetite, nausea, vomiting, and upper abdominal pain; jugular venous distension; depression edema; varying degrees of cyanosis; symptoms such as over-sensitive nerves, insomnia, drowsiness, etc.; cardiac signs: mainly the original contraction performance. It can exist at the same time, the clinical manifestations of ischemic contraction, or the clinical manifestations of ischemic contraction can be the main. Isolated ischemic contraction is rare. The occurrence of complete ischemic contraction due to secondary ischemic contraction after ischemic contraction, and the occurrence of complete ischemic contraction due to severe widespread myocardial disease affecting the heart at the same time, is more common in clinical practice.
