Summary

Thoracoscopic sympathectomy is a rapid and simple technique associated with rare complications, but it is associated with severe postoperative pain that makes breathing and coughing difficult resulting in increased occurrence of pulmonary complications. Paravertebral block has frequently been performed for this procedure but its technical difficulty and safety profile may represent a limitation of its routine use. This prospective, randomized, double-blind controlled study is designed to compare the postoperative analgesic efficacy of ultrasound-guided thoracic retrolaminar block (TRLB) with the paravertebral block in children undergoing thoracoscopic sympathectomy. We hypothesize that ultrasound-guided thoracic retrolaminar block may comparable analgesic effect to paravertebral block with a lesser incidence of complications in pediatric patients undergoing thoracoscopic sympathectomy.

Conditions

  • Pediatric Thoracoscopy

Interventions

PROCEDURE

Retrolaminar block

A high-resolution 5-12 MHz linear probe with a sterile cover will be used to perform the block. The patient will be placed in a prone position with a pillow under the chest. The spinous process of the fourth thoracic vertebrae will be identified and marked. Under complete sterilization, the ultrasound high frequency linear probe will be placed in a para-sagittal position, just lateral to the spinous processes of thoracic vertebra, to identify the vertebral lamina. A 50 mm 22-gauge needle will be inserted in an in-plane technique from cranial to caudal direction and will be advanced till hitting the laminae of fourth thoracic vertebrae and then we will try to inject the local anesthetic, if the resistance to injection is very high, hence we will withdraw the needle slowly and its tip will be kept in its position immediately after disappearance this high resistance. Bupivacaine 0.25%, 0.4mL/kg will be injected.

PROCEDURE

paravertebral group

A high-resolution 5-12 MHz linear probe with a sterile cover will be used to perform the block. The patient will be placed in a prone position with a pillow under the chest. The transverse process of the fourth thoracic vertebrae will be identified and marked. Under complete sterilization, the ultrasound high frequency linear probe will be placed in a para-sagittal position, just lateral to the spinous processes of thoracic vertebra, to identify the vcostotransverse ligament, 0.4mL/kg will be injected
