Portable endoscope monitor for fiberoptic bronchoscope guided endotracheal intubation
Airway management is the primary task in anesthesia and emergency treatment, and difficult airway management is still a difficult point in anesthesia work. The management of difficult airways is closely related to the safety and quality of anesthesia. Repeated operations during difficult endotracheal intubation can cause throat edema and hemorrhage, respiratory tract damage, hypoxia and carbon dioxide accumulation, and even lead to serious complications such as cardiac arrest. Common management approaches for difficult airways include: video laryngoscopy, laryngeal mask-guided intubation, optical cable-guided intubation, fiberoptic bronchoscopy-guided intubation, awake blind intubation, and retrograde cricothyroidotomy Wait. Among them, fiberoptic bronchoscope-guided tracheal intubation is the main method to deal with difficult tracheal intubation, which has the characteristics of small damage, rapid intubation and high success rate. The fiberoptic bronchoscope is soft, has good curvature, and has a clear field of view. It can remove secretions from the mouth, throat, and trachea under direct vision. For special patients with unstable cervical spine and severe cervical spondylosis, there is no need to change the body position during intubation, and it does not block the patient's breathing. Therefore, its intubation is safe and quick, and it does little damage to the patient; when the fiberoptic bronchoscope is intubated through the nose, due to the guiding effect of the nasal passage, it is basically parallel to the laryngeal axis and tracheal axis after passing through the posterior nasal foramen, and the epiglottis, glottis and trachea are not affected. The friction and irritation caused by structures such as the trachea are small; in ICU and respiratory medicine departments, the function of fiberoptic bronchoscopy also includes the diagnosis and treatment of diseases. Although the fiberoptic bronchoscope has the above advantages as the main tool for dealing with difficult airways, in the actual clinical operation, the following problems are often encountered: due to the small and dark field of view of the fiberoptic bronchoscope itself, the anatomical structure is not displayed enough. Clear; the operator is easy to get tired when observing with one eye, and the eyepiece will fog up, which affects the operation; the operator and the observer cannot watch at the same time, which is not conducive to teaching and the mastery of intubation technology, thereby reducing the success rate of intubation. In view of the above situation, we invented a portable endoscope display for the practical problems encountered in the clinical application of fiberoptic bronchoscopy. The monitor used for fiberoptic bronchoscopy-guided tracheal intubation can effectively solve the above problems, improve the success rate of emergency and difficult airway intubation, and ensure the safety of patients. Difficult airway management is always the top priority of anesthesia quality control, which is closely related to the safety and life of patients. Improving difficult airway handling techniques can reduce brain damage, respiratory and cardiac arrest, unnecessary tracheotomy, airway damage and other adverse consequences, and avoid the occurrence of anesthesia accidents. At present, there are many intubation tools in clinical practice, including laryngoscope, light rod, visual light rod, video laryngoscope, etc., but fiberoptic bronchoscopy has always dominated in the treatment of difficult airways. The use of portable endoscope display for fiberoptic bronchoscope intubation will significantly improve the success rate of emergency and difficult airway intubation, thus effectively ensuring the safety of patients. Therefore, the transformation results of this project can be effectively applied in clinical practice, avoiding the occurrence of anesthesia accidents, effectively ensuring the safety of patients undergoing anesthesia surgery, and producing good economic and social benefits.
