Background:
Ultrasound guided nerve block has become popular in pediatric practice. We applied this technique to infants undergoing pyloromyotomy.
Methods:
We retrospectively reviewed the hospital records of infants who underwent pyloromyotomy with the aid of the ultrasound guided nerve block from July 2010 to March 2011.
Results:
Rectus sheath block was performed in 4 infants. In one infant ilioinguinal/hypogastric nerve block was also placed for simultaneous repair of inguinal hernia. There were no complications attributable to the ultrasound guided nerve block.
Conclusions:
We performed ultrasound guided nerve block safely in infants undergoing pyloromyotomy.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
