Local anesthesia is an application that temporarily eliminates the sensation of pain in a specific area of the body. It can be preferred in many procedures such as dental treatments, minor surgical interventions, and dermatological procedures. The method of application, duration of effect, and technique used for local anesthesia vary according to the procedure to be performed and the individual's health condition.
What is Local Anesthesia?
Local anesthesia is a type of anesthesia where a limited area of the body is numbed. During the procedure, the patient remains conscious and does not feel any pain because the area where the procedure is performed is numbed. Local anesthesia, often preferred for minor surgical operations in limited areas, is widely used in interventions applied to areas such as the teeth, eyes, ears, nose, and throat.
How is Local Anesthesia Performed and What Are Its Types?
There are two types of local anesthesia: infiltration and topical. Infiltration is the type of anesthesia that penetrates the tissue. In this method, the anesthetic substance is injected under the skin or other superficial skin tissues with the help of a needle. Topical anesthesia can be described as anesthesia absorbed from the surface. The anesthetic substance is applied to the prepared area for the procedure by dripping, spraying, or smearing. One of the areas where topical anesthesia is commonly used is dentistry.
How Long Does the Effect of Local Anesthesia Last?
After local anesthesia performed by preferring either the infiltration or topical anesthesia methods, a waiting period of 15 minutes before the intervention is necessary for the anesthetic substance to take effect. Although the duration of anesthesia after the intervention may vary depending on its type and amount, the specialist providing the intervention applies the appropriate type and amount of anesthetic substance.
What Are the Differences Between Local and Regional Anesthesia?
While local anesthesia and regional anesthesia have similarities, they are different procedures. In local anesthesia, a limited area where the procedure will be performed is numbed, whereas in regional anesthesia, the numbing process is applied over a larger area. For example, while a very small area on the leg can be numbed with local anesthesia for a procedure, in regional applications, either the whole leg or, if deemed necessary, the entire lower part of the body can be numbed for the intervention. Although the operations for which local or regional anesthesia should be applied are generally outlined, the appropriate method for the operation and patient is decided by the specialist conducting the procedure.
What is the Difference Between Local Anesthesia Injection and Cream?
Local anesthesia injection and cream are two methods that differ in terms of application methods and areas of effect. The local injection provides deeper and more effective numbness by injecting the anesthetic substance directly under the tissue, while the cream form is applied to the skin surface and preferred for more superficial procedures.
The cream is used for laser hair removal, minor dermatological procedures, or to reduce sensitivity before injections. The injection method can also be applied for more comprehensive procedures such as dental treatments and surgical interventions. The preferred method is determined by the physician according to the type of procedure to be performed and the area of application.
Frequently Asked Questions
Does a local anesthesia injection hurt?
During the application of local anesthesia, a mild burning or stinging sensation may generally occur. This feeling is temporary and completely disappears once the effect of the anesthesia begins, significantly reducing the sensation.
What is the purpose of local anesthesia cream and how is it used?
Where and how is local anesthesia performed?
Local anesthesia is applied near the area where the procedure will be performed, and the application method varies depending on the procedure. For instance, in dental treatments, it is injected around the tooth, while during mole removal, it is directly injected into the area. This substance can temporarily halt nerve transmission, preventing the sensation of pain. Topical forms are applied to the skin surface. The expert doctor determines which method and area to choose, and detailed information is essential.
What should be considered after local anesthesia?
After local anesthesia, the feeling of numbness usually passes within 1-2 hours. During this period, hot drinks, hard foods, or impacts that may pose a risk of trauma to the anesthetized area should be avoided. Caution should be taken after dental procedures as the numb area can be bitten unintentionally. A mild pain or ache may occur after the anesthesia wears off; this situation is usually normal. However, if there is excessive swelling, prolonged numbness, or signs of infection, a doctor should be consulted.
