Field block anesthesia can be used in both minor and major surgery, especially in settings where general anesthesia would pose higher risks or is not necessary. For example , this technique is often used for head and neck surgery or for dermatologic procedures such as lesion excision or laceration repair (3).
The document outlines procedures for local infiltration and field block anesthesia , detailing preparation, intradermal, and subcutaneous techniques. It emphasizes the importance of sterile techniques, proper positioning, and the methodical infiltration of anesthetic agents. The document also includes specific patient scenarios for open hernia repair and excision of a nevus, illustrating the ...

Instead of the injection being made directly into the area of the procedure, it is ...
Playing the Field
Local anesthesia is our friend for a multitude of Emergency Department procedures. The main goal is to assure adequate coverage of the area of injury or pathology. Field block anesthesia describes the infiltration of a local anesthetic to an area surrounding a surgical and/or procedure site, resulting in anesthesia of the nerve supply
Field blocks may be undesirable in cases where they obscure the operative anatomy, or where local tissue acidosis from infection prevents effective local anesthetic functioning. Paresthesia Technique Formerly the mainstay of regional anesthesia , this technique is now rarely used for nerve localiza-tion.

Anesthesia of the foot can be accomplished by blocking the five peripheral nerves that innervate the area at the level of the ankle. This technique relies on anatomic landmarks that are easily identified. The ankle block can be used for all types of foot surgery and is safe and reliable, and has a high success rate.
