Introduction

Anesthesia options for strabismus correction surgery include local infiltration anesthesia, surface anesthesia, general anesthesia, basal anesthesia combined with local anesthesia, and nerve block anesthesia. The choice depends on the patient's age, condition, and overall health status. If there is a history of anesthesia allergy or underlying medical conditions, it is recommended to inform the doctor before surgery; medical evaluation for anesthesia risk should be performed when necessary.

1. Local Infiltration Anesthesia: Anesthetic medication is injected around the extraocular muscles to block local nerve conduction. The patient remains conscious during surgery and this method is suitable for cooperative adult patients. It involves minimal surgical trauma and allows for rapid recovery.

2. Topical Anesthesia: Anesthetic eye drops are applied into the conjunctival sac to numb the surface mucosa of the eye. No injection is required. This method is suitable for mild strabismus correction or as an adjunct to other anesthesia techniques to reduce ocular discomfort.

3. General Anesthesia: Anesthetic agents are administered via intravenous injection or inhalation to render the patient unconscious during surgery. This is suitable for children, uncooperative patients, or complex strabismus procedures, ensuring smooth surgical execution.

4. Basal Anesthesia Combined with Local Anesthesia: The patient is first sedated into sleep using medication, followed by administration of local anesthesia. This approach ensures pain-free surgery and rapid postoperative awakening, making it ideal for young children or sensitive adult patients.

5. Nerve Block Anesthesia: This technique precisely blocks nerves related to the eye, providing more focused and longer-lasting analgesia. It is suitable for moderate to severe strabismus surgery and helps reduce the amount of intraoperative anesthetic drugs needed.

After surgery, maintain good ocular hygiene and avoid rubbing the eyes. Use anti-inflammatory eye drops as prescribed. Avoid strenuous activities and exposure to intense light. Eat light, easily digestible foods and ensure adequate rest to promote eye recovery.

Is the incision and drainage surgery for a boil painful?

In general, the level of pain associated with incision and drainage surgery for a boil varies from person to person, primarily depending on the effectiveness of anesthesia, the size and location of the boil, and individual pain tolerance. After surgery, it is essential to strictly follow medical instructions: keep the wound clean and dry, change dressings regularly, avoid squeezing or rubbing the wound, and maintain a light diet avoiding spicy or irritating foods. Seek medical attention if symptoms such as fever or increased redness and swelling at the wound site occur.
