The most common complications in patients with paralysis are the following: 1. Pulmonary infections: most commonly fallopian pneumonia and aspiration pneumonia. Pneumonic pneumonia is mostly caused by the patient’s low activity and poor sputum excretion ability, causing airway secretions and sputum, which collect at the bottom of the lungs. Inhalation pneumonia is caused by the patient’s swallowing dysfunction, choking and coughing when drinking, or accidentally inhaling food residues into the airway when eating; 2. Malnutrition: after paralysis, the patient has weakened digestion, bloating, etc., and eats less, which is more likely to produce hypoproteinemia, and electrolyte metabolism disorders. The hypoproteinemia will lead to general and organ edema, which further leads to the patient’s loss of appetite. Electrolyte disorders are most common with low sodium and potassium, which can lead to poor mental health, weakness, and weakness of the limbs; 3, urinary tract infections: this is mostly seen in patients with retained catheters, or long-term perineum without cleaning, resulting in retrograde entry of bacteria into the urinary tract via the vulva, which can even lead to pyelonephritis in severe cases; 4, decubitus ulcers: long-term paralysis in bed, if not turned in time, often have low hanging parts, pressure parts decubitus ulcers, such as the sacrococcygeal and posterior heel parts. Decubitus ulcers can lead to local infection and ulceration, and are often difficult to heal for a long time.
