He was diagnosed with chronic respiratory failure and was treated with nasal cannula oxygen, budesonide suspension, lobeline hydrochloride injection and salbutamol inhalation aerosol. Basic information] Male, 70 years old [Type of disease] Chronic respiratory failure [Hospital] The First Affiliated Hospital of China Medical University [Date of consultation] January 2021 [Treatment plan] Intravenous injection (Lobelin Hydrochloride Injection) + nebulized inhalation (Salbutamol Inhalation Aerosol, Budesonide Suspension) + oral medication (Ambroxol Oral Solution) [Treatment cycle] 15 days of hospitalization and 1 month follow-up after discharge. 1 month follow-up 【Treatment effect】 somatic symptoms gradually disappeared, physical examination, pulmonary function tests, blood gas analysis, blood routine tests are normal I. Initial Consultation 70-year-old Wang often recurrent coughing, wheezing, coughing white mucus sputum symptoms in the past five years, in the activity, cold, wheezing aggravated, these symptoms can be recurrent, the onset of the decline in the activity of the endurance. Half a month ago, after being exposed to cold, the above symptoms worsened, so he came to our hospital. During the physical examination, he found the presence of barrel chest, and the pulmonary function examination revealed the presence of severe airflow limitation, and the use of blood gas analysis revealed that the partial pressure of blood oxygen was lower than normal, and the partial pressure of blood carbon dioxide was higher than normal, and the routine examination of blood found that the neutrophil and leukocyte levels were significantly higher, and it was considered that there was a chronic inflammation. The blood tests showed a significant increase in neutrophil and leukocyte levels, suggesting that chronic inflammation was present. This suggests that airway spasm caused by inflammation led to chronic respiratory failure, which led to his admission to the hospital for treatment. After the diagnosis of chronic respiratory failure, after communicating with Mr. Wang and with his consent, we adopted a conservative treatment plan, first of all, to provide him with oxygen therapy, inserting a nasal catheter into the nasal cavity, and closely observing Mr. Wang’s respiration, partial pressure of oxygen and carbon dioxide during the process of oxygen inhalation. Respiratory failure often leads to labored breathing. He was given an intravenous injection of Lobelin hydrochloride to stimulate the respiratory center and increase moncler outlet online Wang’s respiratory depth and number of breaths. Salbutamol inhalation aerosol was also used to promote bronchodilation and increase ventilation in the airways. Because of the presence of respiratory inflammation, resulting in airflow restriction in the airway, triggering barrel chest, it is necessary to take inhalation budesonide suspension for anti-inflammatory treatment, and at the same time the use of aminoglutethimide oral solution to resolve phlegm and relieve cough. After 10 days of treatment, the symptoms of cough, wheezing and coughing up white mucus sputum disappeared, and the airflow limitation was reduced by pulmonary function tests. Blood gas analysis revealed that the partial pressure of oxygen and carbon dioxide were normal, and the neutrophil and leukocyte levels were normalized by routine blood tests, which was considered to alleviate the inflammation in the airway, and the use of Lobeline hydrochloride injection was stopped. After 15 days of medication, moncler outlet online the barrel chest disappeared, no breath-holding after activity, and activity endurance was normal. Budesonide suspension and salbutamol inhalation aerosol were discontinued, and the nasal cannula was withdrawn, and arrangements were made for discharge from the hospital, with no obvious abnormalities in the follow-up examination 1 month after discharge. Fourth, precautions moncler outlet online After medication, the condition improved to my delight, in order to prevent the recurrence of respiratory failure after discharge, moncler outlet online also need to pay attention to regular breathing exercises, such as abdominal breathing or lip-contracting breathing, which can enhance the respiratory function. After the condition is stabilized, you can go outdoors and breathe fresh air. Daily living indoor diligent gout, keep the temperature and humidity suitable. If abnormal symptoms such as labored breathing, skin congestion and elevated blood pressure occur after discharge from the hospital, return to the hospital as soon as possible for review. Maintain a good and optimistic mindset, do not be too nervous and anxious, so as not to hinder the body’s recovery of bad emotions.
