How to Say It: Trans-ver-suss Abb-domm-in-us Plane Block
A transversus abdominis plane (TAP) block is a form of anesthesia that numbs the front of the abdominal wall. The medication is injected over nerves that lie between two layers of abdominal muscles, the internal oblique, and the deeper transversus abdominis muscle.

A TAP block is done to numb the upper and lower abdomen. After a TAP block, a person should not be able to feel pain during abdominal, gynecological, and urological procedures and surgeries. This can also continue to provide pain relief after the surgery is complete. This may lower the need for prescription pain relievers.
Problems are rare, but all procedures have some risk. The doctor will go over some problems that could happen, such as:
People who have an infection at the injection site may be at greater risk of problems.
The care team may meet with you to talk about:
Local anesthetic will be used. The area will be numb.
A needle will be inserted in the front of the abdomen just below the ribcage or to the side between the ribs and the pelvis. An ultrasound will be used to locate the best place to insert the needle. The ultrasound will also let the doctor know when it is in the correct place. Then, the anesthesia medication will be injected and the needle will be removed.
The procedure will take only a few minutes, but the block will take an hour to reach full effect.
The injection may burn or sting for a few seconds. After that, you should not feel pain.
How long you stay depends on why you needed the injection.
