Summary

The purpose of this research study is to find the best way to decrease pain in children right after surgery whom have had their hernia fixed. Right now, there are two different ways surgeons and anesthesia providers try to decrease pain. It is not clear if one way is better than the other. The method used is often chosen by which one the doctor has more experience using. The Investigator plans to find out if one of the methods is more effective and/or safer than the other method. The results of this study will help learn how to best control pain in children having surgery for hernia repair.

Detailed description

Unilateral inguinal herniorrhaphy is a commonly performed surgical procedure in the pediatric population. Multimodal anesthesia consisting of systemic narcotics, surgical wound infiltration with local anesthetic and ilioinguinal and/or iliohypogastric nerve blockade has traditionally been employed to achieve acceptable analgesia. Recently, ultrasound-based studies have demonstrated that blind abdominal wall injections are done with poor accuracy. Ultrasound-guided alternatives, such as the transverses abdominis plane (TAP) block, may improve analgesic efficacy and patient comfort in the post-operative period when compared to blind landmark based nerve blockade. There has been increasing utilization of the TAP block in the adult population due to the described ability to provide effective blockade of the thoracolumbar spinal nerves innervating the abdominal wall. We propose a randomized prospective evaluation of the analgesic efficacy comparing surgeon performed ilioinguinal/iliohypogastric block with ultrasound-guided TAP blockade in healthy ASA I and II pediatric patients undergoing unilateral herniorrhaphy on an outpatient basis.

Conditions

• Pain
• Inguinal Hernia

Interventions

Type	Name	Description
PROCEDURE	TAP Block	While the terminal branches of T7 to L1 cannot be visualized under ultrasound as they pass between the internal oblique and the transverse abdominis muscles, they are expected to lie within this plane. The three muscular layers of the abdominal wall, however, can be easily identified under ultrasound guidance. A needle is advanced under ultrasound guidance towards the fascial plane that separates the internal oblique and the transversus abdominis muscles, at which point local anesthetic is deposited under direct visualization.
PROCEDURE	Ilioinguinal/iliohypogastric blockade	Ilioinguinal and iliohypogastric blockade is performed as an injection after palpation of the anterior superior iliac spine followed be a perceived loss of resistance with insertion of the needle, or may be infiltrated locally following herniorrhaphy exposure as anatomic landmarks can prove to be difficult to locate in the anesthetized pediatric patient.
