What preparations should be made before the operation?
Zhongshan professor of ophthalmology surgery has strict and detailed preparations before ophthalmic surgery. The purpose of these preparations is to ensure a safe and smooth operation process and reduce the risk of discomfort and complications for patients. The following is a detailed introduction to the preparations before surgery from four aspects.
Patient's physical preparation
Before ophthalmic surgery, the patient's physical condition needs to be comprehensively evaluated and checked to ensure the feasibility of surgery. First of all, the doctor will inquire about the patient's medical history, understand the patient's allergy history, disease history, surgery history, etc., and conduct physical examination of the patient, including measuring physiological parameters such as temperature, pulse, blood pressure, etc. The doctor will also require the patient to carry out some necessary laboratory tests, such as blood routine test, coagulation function, etc., to evaluate the patient's general condition.
In addition, patients need to stop certain drugs before surgery, such as blood thinners, antiplatelet drugs, etc., to reduce the risk of bleeding during surgery. If the patient has concomitant diseases, such as hypertension and diabetes, further special treatment is required to ensure the safety during the operation.
In terms of diet, patients need to follow the doctor's advice before surgery, and generally require admission on an empty stomach to avoid complications such as aspiration of stomach contents during surgery.
Eye preparation
Before the operation, the doctor will conduct a comprehensive ophthalmic examination of the patient's eyes, including vision examination, intraocular pressure measurement, corneal topography, fundus examination, etc., to determine the indications and operation plan of the operation. The doctor will also carry out special examinations such as eye B-ultrasound, corneal topography, tear influence, etc. to help more accurately assess the patient's eye condition.
On the day before surgery, patients need to thoroughly clean their eyes to keep them clean and dry. One night before the operation, the doctor will ask the patient to drip eyedrops to reduce the risk of infection and eye discomfort after the operation.
For some special ophthalmic operations, such as cataract surgery, patients also need to carry out some special eye preparations, such as the use of mydriasis drugs in advance, eyelid disinfection, etc., so that the operation can be carried out better.
Preparation of surgical equipment and materials
Before the operation, the doctor needs to prepare the instruments and materials needed for the operation. For ophthalmic surgery, doctors need to prepare a series of surgical instruments, such as scalpels, surgical tweezers, eye retainers, etc. At the same time, some special ophthalmic materials need to be prepared, such as intraocular lens, eye silica gel, corneal graft, etc., to meet the needs of surgery.
The preparation of surgical instruments and materials requires high accuracy and standardization. Doctors need to select appropriate instruments and materials in strict accordance with the operation plan and the patient's situation, and ensure their quality and integrity.
Team preparation
Before the operation, the doctor also needs to fully communicate and prepare with the team members. During the operation, doctors need to cooperate with other team members, such as nurses, anesthesiologists, etc. Therefore, doctors need to discuss the operation plan with team members, determine the division of work, clarify responsibilities, and carry out necessary training and drills.
Before surgery, team members also need to check and prepare surgical equipment to ensure that the instruments and equipment during surgery work normally. The doctor also needs to discuss the anesthesia plan with the anesthetist, assess the anesthesia risk of the patient, and prepare for anesthesia in advance.
In a word, Zhongshan professor of ophthalmology surgery will make comprehensive preparations before ophthalmic surgery, including patient's physical preparation, eye preparation, surgical equipment and materials preparation, and team preparation. The purpose of these preparations is to ensure the safety and smooth operation.
As the main body of surgery, patients need to actively cooperate with doctors and the team, make preparations before surgery according to the guidance of doctors, so as to improve the success rate and effect of surgery.
