No results posted yet for this study

Summary

Erector spinae plane block is new interfascial plane block, and can be applied to management of thoracic neuropathic pain syndromes. The target of needle is deeper(or anterior) to the erector spinae muscle. So it is more safe and simple technique than prior technique, thoracic paravertebral block. The aim of this study is the evaluation of erector spinae plane block comparison to prevertebra block.

Conditions

  • Thoracic Postherpetic Neuralgia

Interventions

PROCEDURE

erector spinae plane block (20 mL of 0.25% ropivacaine with dexamethasone 5mg)

In group E, The patient was placed in a sitting position and a high-frequency linear ultrasound transducer was placed in a longitudinal orientation 3 cm lateral to the thoracic spinous process. Three muscles were identified superficial to the hyperechoic transverse process shadow as follows: trapezius, rhomboid major, and erector spinae. An 8-cm 22-gauge block needle was inserted in a cephalad-to-caudad direction until the tip lay in the interfascial plane between transverse process and erector spinae muscles, as evidenced by visible linear spread of fluid between erector spinae muscles and the bony acoustic shadows of the transverse process. A total of 20 mL of 0.25% ropivacaine with dexamethasone 5mg was injected here.

PROCEDURE

thoracic paravertebral block(10 mL 0.25% ropivacaine with dexamethasone 5mg)

2\) In group P, an appropriate thoracic spinous precess is located by positioning the probe in the transverse plane. Then the probe is moved laterally to locate the transverse process. The probe is manipulated slightly caudad or cephala to locate the intercostal space. The transverse process is visualized medially with the pleura dipping under the inferolateral aspect. The internal intercostal membrane, which is contiguous with the superior costotransverse ligament, was generally seen as a thin, radiopaque line extending from the transverse process, creating a wedge-shaped pocket, which represents the thoracic paravertebral space. A 22-gauge, facet-tip needle is advanced, in plane, from the lateral aspect of the ultrasound probe. When the needle pierced the internal intercostal membrane, and after aspiration demonstrated the absence of air or blood, 10 mL 0.25% ropivacaine with dexamethasone 5mg deposited in 5-mL increments.
