Summary

Regional analgesia for inguinal hernia repair in children has attracted increasing interest and different techniques like Caudal block, lumbar epidural block, wound infiltration, Ilio-inguinal nerve block and paravertebral block have been used with varying success. Ilio-inguinal nerve blockade has been widely used in this context but the duration of the block is also limited to the early postoperative period. Paravertebral blockade has been shown to produce long lasting postoperative analgesia when used in combination with general anaesthesia in paediatric herniorrhaphy . Ultrasound-guided retrolaminar block is one of the newer and technically simpler alternatives to the traditional PV block . The aim of this study is to test the efficacy and safety of ultrasound guided retrolaminar block(RLB) as an analgesic technique in surgery of pediatric inguinal hernia in comparison with with ilioinguinal nerve block(INB). It is hypothesized that RLB block will provide longer duration of postoperative analgesia than INB with few side effects.

Conditions

  • Inguinal Hernia
  • Pediatric

Interventions

PROCEDURE

General anaesthesia

General anaesthesia will be induced with 8% sevoflurane in oxygen and maintained with 1 MAC sevoflurane via a laryngeal mask.

PROCEDURE

Ultrasound-guided RLB

The suggested ultrasound transducer orientation is sagittal paramedian (cephalacaudad direction). We begin our ultrasound scanning in a paramedian sagittal plane by finding desired level (T12- L1).The transverse process view, the costotransverse ligament can be visualized above the paravertebral space. Continuing to scan from lateral to medial, the vertebral laminae come into view.

PROCEDURE

Ultrasound-guided INB

A high-frequency probe is placed medial to the anterior superior iliac spine with the axis facing the umbilicus. A needle is inserted toward the ilioinguinal nerve as it runs between the transversus abdominis and internal oblique.

DRUG

Bupivacaine

0.3 ml.kg of 0.25% bupivacaine will be injected under visualization.
