Posterior bulbous retardation anesthesia technology

Abstract

The invention belongs to the technical field of medical treatment and ophthalmology, and discloses a post-bulbous block anesthesia technology, which comprises the following specific operation steps: dotting an eye for 1-2 times by using a surface anesthetic in advance, after 5 minutes, making an incision on a conjunctiva at the bottom of a dome corresponding to a lacrimal punctum under an operation eye under direct vision of a microscope, and then performing post-bulbous block anesthesia on the conjunctiva at the bottom of the dome; the bulbar conjunctiva, the bulbar fascia and the sclera are fully separated, and the porcelain white sclera is exposed. Repeated experiments show that an incision with the size of about 2mm is formed in the dome bottom conjunctiva corresponding to the lacrimal punctum under the operation eye, bulbar conjunctiva, bulbar fascia and sclera are fully separated, the porcelain white sclera is exposed, then medicine injection is conducted through a self-made improved injection needle, the good anesthesia effect can be achieved, and the technical scheme is standard, simple and normative in operation, low in cost and suitable for large-scale popularization and application. The learning curve is short, the anesthetic effect of conventional postglobular retardation anesthesia (5-6 ml) can be achieved by using a small amount of anesthetic (about 4 ml), and no serious anesthesia complications are generated.

Description

technical field [0001] The invention belongs to the field of medical technology-ophthalmology technology, in particular to a technique of retrobulbar block anesthesia. Background technique [0002] General anesthesia is the "true standard" of anesthesia for ophthalmic vitrectomy surgery, but it is time-consuming, expensive, and the risk of intraoperative and postoperative anesthesia restricts the wide application of general anesthesia in ophthalmic vitrectomy surgery. Especially with the widespread development of minimally invasive vitrectomy surgery, the operation time is short and the trauma is small, retrobulbar anesthesia is still the first choice of many ophthalmologists. Good retrobulbar block anesthesia can fully anesthetize and fix the eyeball, fully satisfying the surgical operation, but the frequency of complications caused by anesthesia is also high. Generally, minor complications do not affect the operation, and severe complications (such as severe eye center Re...

AI Technical Summary

Problems solved by technology

Since Tenon's subcapsular anesthesia can only inject anesthetics under Tenon's capsule, which is far away from the ciliary ganglion, the onset time of anesthesia is longer, and complications such as insufficient anesthesia, bulbar conjunctiva and bulbar fascia swelling also affect the vitreous Incision surgery performed
