Like many serious diseases, patients with cerebral hemorrhage suffer from many complications. 88% of patients with cerebral hemorrhage suffer from at least one complication, and 40% of these patients suffer from life-threatening complications. According to statistics, deaths due to complications account for 50% of all deaths in patients with cerebral hemorrhage. And pneumonia has the first place among complications, accounting for 5.6%. Patients with cerebral hemorrhage are prone to pneumonia due to a combination of unconsciousness, vomiting, difficulty swallowing, prolonged bed rest, coughing and coughing weakness, etc. Among all the complications of brain hemorrhage patients, the chance of complicating pneumonia is the highest, accounting for 5.6%. Pneumonia is the inflammation of the lungs. It can be caused by pathogenic microorganisms such as bacteria, viruses, fungi, and parasites, as well as physicochemical factors such as radiation and inhaled foreign bodies. The most common cause of pneumonia in patients after brain hemorrhage is difficulty swallowing and inhalation of vomit. When many patients with brain hemorrhage are awake, their families will ask the doctor if they can feed them something, and the answer given by the doctor is completely different for different patients. Why is that? The answer is that the degree of swallowing difficulty varies. Difficulty in swallowing may seem like a small thing, but success or failure comes from the details. It is said that a thousand miles of dike is destroyed by an anthill, and this is the truth. The human throat can be seen as a trigger worker, usually the mouth and trachea are open, so you can breathe, speak, etc. But when you do swallowing action between the mouth and esophagus is connected, and the trachea is temporarily closed to prevent food from entering the trachea. After food enters the trachea the body defensively develops a violent cough to shock the foreign body out of the trachea, as these foreign bodies can easily lead to a disease, aspiration pneumonia. Healthy people are under this double protection, but patients with brain hemorrhage are sometimes unable to complete swallowing motions or have slow swallowing motions, and then foreign bodies enter the esophagus, and if the cough reflex is also impaired, then the double protection fails and the patient develops aspiration pneumonia. In severe dysphagia, nothing can be eaten because whatever the patient eats will enter the trachea, and in the most severe cases, the patient will suffocate because a mouthful of food enters the airway, which is commonly known as “choking”. Mild dysphagia often manifests itself as choking when eating liquids, because liquids flow faster and can fit into various gaps, which can easily enter the trachea when the trachea is closed slowly or incompletely, causing choking and coughing. If the choking cough is not strong enough, the liquid will flow into the bottom of the lungs due to gravity to produce pneumonia. What is the incidence of dysphagia when it is so troublesome? It has been reported in the literature that about 68% of patients with brain hemorrhage will have varying degrees of dysphagia. The main clinical symptoms of aspiration pneumonia are fever, cough, sputum, and blood in the sputum, which may be accompanied by dyspnea. If pneumonia is not effectively controlled, it may progress rapidly, with respiratory distress (2%) and sepsis (1.7%), at which point the likelihood of patient death is greatly increased. The incidence of pneumonia is high among patients with cerebral hemorrhage, and there are extremely high numbers of cases of death due to pneumonia. The patient’s family often cannot understand why the cause of death is pneumonia when there is a hemorrhage in the brain. In the face of pneumonia patients with high fever and thick sputum, the most effective way is to turn, pat the back, promote sputum discharge, and then supplemented with effective antibiotics to treat both the symptoms and the root cause; on the contrary, everyone’s idea of using better antibiotics is not so miraculous effect.
