Anesthesia depth analysis.

The success of ophthalmic surgery, which is a medical field with very high operational requirements, is based not only on the skill of doctors, but also on the management of anaesthesia before and after the operation. Anaesthesia, a central part of eye surgery, is designed to create a pain-free and calm environment for patients, thus facilitating the precise operation of doctors. First, the central requirement of ophthalmological anesthesia is to ensure its smooth and safe operation. To this end, the process of anaesthesia must strictly comply with the following core requirements: to ensure pain and comfort: to ensure, by means of anaesthesia, that there is no pain in the area and surroundings of the operation, while keeping the patient relaxed and avoiding the disruption of the operation by pain or stress. (b) Keep the eyeball movement as it is: after anaesthesia, the patient ‘ s eye shall be able to move passively and freely so that the doctor can perform the necessary observation and surgery. Controlling eye pressure stability: In eye surgery, eye pressure must be strictly controlled to prevent loss of eye content or optic nerve damage that may result from its rise. Adapting to special position needs: Some ophthalmological operations require the patient to take a specific position, such as subsidement. Anaesthesia programmes need to take this factor fully into account to ensure the comfort and safety of patients during surgery. 2. The various forms of anaesthesia in eye surgery are varied, and doctors choose the most appropriate anaesthesia programme, depending on the type of operation, age of the patient, physical condition, etc. The following are common methods of anaesthesia: surface anesthesia: drops of permeable local anesthesia into the clinker capsule, absorbing through mucous membranes, hindering the transfer of the nerve ending. Application: Short-lived operations such as cataracts and glass cavity injections. Advantages: Operations are simple and fast and patients do not need to fast. Post-ball obstructive anaesthesia: The drug is injected directly into the muscle cone at the rear of the eyeball, blocking the transmission of lashes and lashes. Application: Longer-term eye-floor operations such as retina decomposition and silicon oil extraction. Characteristics: Anaesthesia has a reliable and relatively complex operation. (b) The principle of local impregnation of anaesthesia: local anaesthesia is injected around the surgical area, creating a limited anaesthesia area. Application: Small-scale operations such as wing-shaped poaching. Advantages: The extent of anaesthesia is limited and has a small effect on the patient ‘ s body. (c) The principle of combined anaesthesia of target control: the computer accurately controls the intravenous system and regulates blood drug concentrations to maintain stable anaesthesia. Application: Long-term and possibly stressless surgery. Characteristics: Patients are subject to fasting while maintaining their self-consciousness and breathing. All-body anaesthesia: the delivery of anaesthesia by means of an vein or inhalation leads to a loss of consciousness and sensory loss of reversibility. Application: Large-scale operations such as pediatric ophthalmology, optic neurosurgery, osteoporosis, etc. Characteristics: The effects of anaesthesia are complete and thorough, but recovery after surgery is relatively long. iii. Careful preparation of anesthesia prior to anaesthesia, in order to ensure the safety and effectiveness of anaesthesia, requires the patient to be fasted prior to surgery: Depending on the method of anaesthesia, the patient is required to stop eating and drinking water at some point in advance in order to prevent the risk of vomiting and misuse during anaesthesia. Comprehensive assessment of the state of the body: The doctor conducts a thorough examination of vital signs such as blood pressure, heart rate and blood sugar to assess their suitability for anaesthesia. Drug dosage adjustment: If a patient suffers from chronic diseases such as hypertension and diabetes, the doctor must be informed in advance in order to adjust the dose or treatment to the condition. Psychological adjustment and preparation: understanding of the procedure and the anesthesia, and the elimination of tension and fear contribute to the smooth operation and rapid recovery after the operation. 4. After anaesthesia is completed, the patient is required to follow the following care to promote full physical recovery: close observation and monitoring: after anaesthesia, the patient is required to be closely observed and monitored in an anaesthesia recovery room for a period of time to ensure the smooth and normal functioning of life signs. Gradual recovery of diet and activities: In accordance with the method of anaesthesia and the doctor ‘ s advice, the patient may gradually start eating and carrying out daily activities. Pain management and relief: Minor pain may occur after the operation and the patient may use painkillers as prescribed by the doctor. Regular referral and assessment: After the operation, regular visits to the hospital are required in order for the doctor to make an accurate assessment and guidance on the effects and recovery of the operation. Anesthesia is an important guarantee of success. Through an in-depth understanding of the core requirements of anaesthesia, diversity, pre-surgery preparation and post-surgery care, patients can be more active in working with doctors to complete the operation and ensure its smooth and safe. Remember that good communication and communication with doctors and timely feedback on health conditions and needs are key to successful operations.
