Diagnosis and treatment of ear, nose and throat diseases often involve a variety of start-up operations, and surface anesthesia is an important element in ensuring the smooth running of these operations.
In recent years, with advances in medical science and technology, new technologies have emerged in the field of osteoporosis in ear, nose and throat, which has brought new ideas and approaches to clinical practice.
I. Importance of osteoporosis
(1) An examination and surgery in the ear, nose and throat section, such as larynx examination, endoscopy surgery, etc., stimulate sensitive mucous tissue. Effective surface anaesthesia can significantly reduce the pain and discomfort of patients and make them more supportive of the process.
(2) To ensure that the operation is carried out smoothly, the cooperation of the patient during the operation or examination is essential. Good surface anaesthesia avoids disruption of operations caused by a patient ‘ s pain reflection, improves the accuracy and safety of operations and reduces the occurrence of complications.
Introduction to new technologies
(1) New types of surface narcotic drugs
1. Some new types of ultra-long local anesthesia have been developed. They have unique chemical structures that can be more stablely integrated with receptors in the neurological membranes, thus prolonging anaesthesia. For example, a new type of long-acting aesthetic is used for larynx surgery, which can last several hours and meet the demands of complex operations.
2. Low-sensitized anesthesia has been developed in response to the problem of the vulnerability of traditional anesthesia to allergies. These drugs reduce the risk of allergies of patients by changing molecular structures or adding special ingredients, and expand the advanced delivery system for the applicable population (2)
1. Nanopharmaceutical delivery systems. Nanotechnology is used for delivery of surface narcotic drugs. The nanoparticles can be packaged with anaesthesia, allowing them to target more precisely the nerve endings below the mucous membranes. When the nasal cavity is given, the nanotransmitting system enables the drug to bypass the mucous layer, directly affects the nerve, improves the anaesthesia and reduces the use of the drug.
2.3D Print-to-medicine 3D printing technology for the manufacture of personalized delivery devices. Based on the patient ‘ s ear, nose and throat anatomy structure, the type of device printed is more evenly and accurately sprayed on the mucous surface. For example, in ear surgery, this customized device ensures that the drug covers all areas requiring anaesthesia.
(3) Combined anaesthesia techniques
1. Multiple combinations of anaesthesia. For example, the use of both esters and esters and aamides asaesthetics can improve the depth and breadth of anaesthesia by blocking the transmission of nerve impulses in different ways.
2. Combined use of narcotic and assistive substances, such as vascular constrictors. In nasal surface anesthesia, the combination of anaesthesia and angiogenic constrictors reduces nasal mucosa, improves the vision and prolongs the time of anaesthesia by constricting the absorption of anaesthesia. Clinical applications
(1) Use in ear surgery. In ear surgery, such as drum repair, mid-ear mast surgery, etc., new technologies can achieve more accurate anesthesia. Nanopharmaceutical delivery systems can deliver anaesthesia to the neurological depths of the inner ear, reduce the impact on the surrounding tissue and increase the safety and success of the operation.
(2) The application of nasal endoscopy and nasal insulation, etc., in nasal surgery benefits from 3D-printing devices and joint anaesthesia techniques. The effective anesthesia of the nasal cavities and the reduction of the bleeding and suffering of the patients in the surgery help the surgeon to operate more clearly.
(3) The application of new long-acting anesthesia and low-sensitivity anesthesia can ensure long-term anaesthesia, reduce the risk of allergy, guarantee the smooth operation and reduce complications such as post-operative pain in the throat.
Strengths and challenges
(1) Strengths
1. Improving the quality of anaesthesia. New technologies have improved the quality of surface anaesthesia from a variety of sources, including drugs, delivery systems and joint applications, providing more reliable anaesthesia for ear, nose and throat treatment.
2. Improvement of patient experience reduces the pain and fear of the patient and facilitates post-operative recovery and acceptance of subsequent treatment.
(2) Challenges
1. Costs. New technologies tend to be associated with high costs, including the development, production and use of new drugs and advanced delivery devices, which limit their diffusion in some areas. 2. Technical training. The need for health-care personnel to acquire new methods of using anaesthesia technology and equipment requires specialized training, which makes clinical application more difficult. New technologies of epinalphage in ear, nose and throat provide many opportunities and hope for clinical practice. While there are some challenges ahead, with the further development and refinement of the technology, it is expected that it will be widely applied in the field of ear, nose and throat, with better treatment for patients.
