Fiberoptic bronchoscopy (referred to as fiberoptic bronchoscopy) is one of the important tools for the diagnosis and treatment of respiratory diseases, and its indications are very broad, such as diffuse lung diseases (interstitial lung diseases), lung malignancies, infections, and airway diseases. Some new diagnostic techniques in recent years, including ultrasonic bronchoscopy, brachytherapy, cryotherapy, airway stent placement, balloon dilation, and electrocautery, all use bronchoscopy as the basic instrument. In China, most hospitals currently use the traditional anesthesia method of local surface anesthesia in the pharynx during fibronectomy. Patients undergo the examination in the awake state, and when the fibroneuroscope enters the vocal cords and the airways below the vocal cords, patients are prone to coughing, breath-holding, nausea and other discomfort. Some patients lose valuable treatment time and bring great pain to themselves and their families. However, now patients who need to undergo fibrinoscopy need not worry anymore! A more effective, safe and less painful method of bronchoscopy has been developed in the clinic, and this is – painless bronchoscopy, which means that patients can complete bronchoscopy without any pain! Painless bronchoscopy is actually a bronchoscopy performed under intravenous anesthesia, with the cooperation of a respiratory physician and an anesthesiologist. The anesthesiologist selects the type of anesthesia and intravenous anesthetic according to the requirements of the examination and the patient’s condition, and monitors the safety of the procedure. The intravenous anesthetics applied during bronchoscopy have rapid onset and short duration of action, with good sedative and analgesic effects and memory deficit, and the patient can wake up soon after stopping the drug. Painless bronchoscopy is suitable for patients of all ages, and is particularly safe for young children. It can be used for basically all examinations requiring bronchoscopy, except for transbronchial lung biopsy (which requires the patient’s awake cooperation). Painless bronchoscopy has the following advantages: patients are examined in a quiet and comfortable state, they have no bad memories after waking up, and they have no fear of undergoing the procedure again, which is especially suitable for patients who need repeated fibronectomy. The examination process is safe, easy to administer medication, and the recovery is rapid. With the anesthesiologist’s escort and no obvious adverse reactions during the examination, the doctor can observe the lesion more carefully and clearly, so that the required operation can be completed quickly and accurately. Before the painless fibrinoscopy, the results of recent chest or lung CT films, electrocardiogram, blood gas analysis, coagulation function, and routine blood tests should be prepared. Patients should fast one meal before the examination and abstain from water 3 hours before the examination. Lidocaine nebulized inhalation is given first to fully anesthetize the patient’s airway with anesthetic for 10-15 minutes. The patient removes the denture, glasses, and reclines with the pillow removed, opens the intravenous access, routinely connects the cardiac monitor, monitors and observes the patient’s blood pressure, pulse, respiration and transcutaneous oxygen saturation, and then performs intravenous anesthesia, and is ready for bronchoscopy. After painless bronchoscopy, the patient is usually awake in a few minutes after stopping the intravenous anesthesia, and can leave the bronchoscopy room after another half hour or so of observation without any obvious adverse reactions. The postoperative precautions are the same as those for traditional anesthesia, and include the following: food and water are strictly prohibited for up to 2 hours after the procedure, the reason being to prevent the inadvertent introduction of food into the trachea due to the incomplete elimination of the anesthetic effect in the pharynx after the procedure. If patients undergo intraoperative irrigation, there will be transient postoperative hypothermia and slight bleeding, which will usually resolve on its own. In patients with intraoperative biopsy, a small amount of blood in the sputum may occur during postoperative coughing, and no special treatment is usually required. If the amount of hemoptysis is high, it should be closely observed so that appropriate measures can be taken in a timely manner. In addition, attention should be paid to the presence of anesthetic allergy, nasal mucosal injury, pneumothorax, bronchospasm, cardiovascular complications, etc. Since the painless tracheoscopy was carried out, it has been generally well received by patients. For patients who need to do tracheoscopy, you can choose with confidence that receiving tracheoscopy without pain is not a dream!
