Question
Which of these statement(s) is/are correct regarding field block anesthesia?I. Local anesthetic is infiltrated subcutaneously whilst withdrawing the needleII. Local anesthetic should be infiltrated directly into a wound edgeIII. The area of skin containing the planned anesthetic field should be disinfectedIV. The anesthetic field can be massaged with gauze after infiltration
Solution 1
The statements that are correct regarding field block anesthesia are:
I. Local anesthetic is infiltrated subcutaneously whilst withdrawing the needle: This is correct. The local anesthetic is usually injected subcutaneously, and the needle is slowly withdrawn to ensure that the anesthetic is evenly distributed in the tissue.
III. The area of skin containing the planned anesthetic field should be disinfected: This is also correct. Before any type of anesthesia is administered, the skin should be thoroughly cleaned and disinfected to prevent infection.
The statements that are not correct are:
II. Local anesthetic should be infiltrated directly into a wound edge: This is not correct. Injecting anesthetic directly into a wound edge can cause further tissue damage and may not provide adequate anesthesia.
IV. The anesthetic field can be massaged with gauze after infiltration: This is not typically recommended. Massaging the area can cause the anesthetic to spread to areas where it is not needed, and it can also cause discomfort or pain to the patient.
