This invention discloses the application of low-concentration topical anesthetics in ophthalmic surgery, relating to the field of low-concentration topical anesthetic application technology, including the following specific application process: confirming the patient's basic surgical condition before administration; selecting anesthetic drugs and optimizing the administration concentration; performing administration according to the specific situation; real-time dynamic monitoring and adjustment of the administration dosage; gradually reducing the drug and transitioning to withdrawal. This invention improves drug safety and patient compliance while ensuring analgesic effects by optimizing anesthetic drug concentration and administration method. Furthermore, by using topical anesthetics at concentrations lower than conventional anesthetics for local administration after ophthalmic surgery, it can effectively relieve postoperative pain, discomfort, and foreign body sensation while significantly reducing toxic effects on corneal epithelial cells, reducing delayed corneal healing, dry eye, and corneal damage. It is effectively applicable to analgesia management after pterygium excision, refractive surgery, and other common ophthalmic surgeries, and has good clinical application value.

The invention relates to the technical field of oral anesthesia, in particular to an oral hydrogel topical anesthesia patch and a preparation method thereof. The hydrogel surface anesthesia patch comprises a composite hydrogel base material and an anesthetic loaded on the composite hydrogel base material, the novel composite hydrogel comprises the following components in percentage by mass: 8%-15% of sodium carboxymethyl cellulose, 4%-8% of hyaluronic acid, 6%-12% of polyvinyl alcohol, 4%-9% of quaternized modified chitosan, 3%-7% of poly gamma-glutamic acid, 2%-6% of an adhesion regulator, 2%-5% of a humectant, 0.5%-2% of a cross-linking agent and a proper amount of water. The anesthetic is lidocaine or tetracaine, and the mass fraction of the anesthetic in the oral hydrogel topical anesthesia patch is 2%-8%. According to the invention, quaternized modified chitosan and poly gamma-glutamic acid are taken as core functional components, and a novel composite hydrogel base material system of sodium carboxymethyl cellulose, hyaluronic acid and polyvinyl alcohol is combined, so that the application property and slow release property of the surface anesthesia patch are ensured.

This invention discloses a traditional Chinese medicine composition for improving acne, consisting of Platycodon grandiflorus, Citronella rotundus, Taraxacum mongolicum, Angelica dahurica, Angelica sinensis, fermented soybean, Prunus persica, and Saffron. Studies have shown that anti-inflammatory Western medicines, heat-clearing and cooling traditional Chinese medicines, and topical anesthetic acne-removing drugs can constrict visceral capillaries or inhibit skin heat dissipation nerves, causing the body's heat to be unable to dissipate normally. This leads to increased heart rate and abnormally increased facial blood flow through hypothalamic regulation, compensating for heat loss and forming acne, while also increasing the burden on the heart. Long-term renal capillary constriction can also disrupt bone marrow hematopoietic homeostasis and increase the risk of leukemia. Platycodon grandiflorus, Citronella rotundus, Taraxacum mongolicum, Angelica sinensis, and Prunus persica can dilate visceral microvessels; Angelica dahurica bidirectionally regulates skin-visceral blood flow; fermented soybean stabilizes the body temperature center; and Saffron, within a safe dosage of 0.5-2 parts, bidirectionally regulates microvessels, achieving anti-inflammatory effects on the face, heat dissipation in the internal organs, and kidney protection and detoxification. This invention combines various drugs to dilate visceral blood vessels, stabilize central body temperature regulation, and suppress compensatory heart rate and facial congestion, thereby improving acne and acne scars from the root cause. It also protects the heart, kidneys, and blood system. The medicine is mild and can be taken for a long time. It is hormone-free, does not cause drug resistance, and is not prone to recurrence, making it suitable for industrial application.

An apparatus for dispensing topical anesthetic is described. The apparatus includes a pouch, a cover material, and a topical anesthetic. The pouch includes a containing material, and the pouch contains the topical anesthetic. A method of administering topical oral anesthetic using the pouch is also described.
