No results posted yet for this study

Summary

The aim of this study is to compare the analgesic efficacy of erector spinae plane block versus thoracic paravertebral block versus quadratus lumborum block on postoperative analgesia after pelvi-ureteric surgeries.

Conditions

  • Erector Spinae Plane Block
  • Paravertebral Block
  • Quadratus Lumborum Block
  • Analgesia

Interventions

PROCEDURE

ESPB Technique

The patient will be in sitting position. The probe will be positioned with longitudinal alignment, 3 cm lateral to the spinous procedure of T8 to obtain a parasagittal view. An echogenic needle will be introduced from the caudal end of the probe and advanced in-plane direction until the needle tip hit the tip of the transverse process. Bupivacaine will be afterwards injected into the erector spinae plane block. Linear spread cranially and caudally below the muscle upon injection will be visualized on the US screen indicating successful block.

PROCEDURE

TPVB Technique

The patient will be in sitting position. The probe will be positioned with longitudinal alignment, 3 cm lateral and parallel to 8th spinous process till transverse process, superior costotransverse ligament, and pleura will be visualized then lateral tilt of the probe was done for better visualization of the PVS between the superior costotransverse ligament and the pleura. An echogenic needle was introduced at caudal end of transducer using the in-plane technique till piercing the superior costotransverse ligament . Bupivacaine will be injected into the PVS with downward displacement of the pleura indicating a successful block.

PROCEDURE

QLB Technique

The patient will be in lateral position. The probe will be placed above the iliac crest. The Petit's triangle will be identified. The three abdominal muscles (i.e., the external oblique, internal oblique and transversus abdominus muscles) will be detected. Both the external oblique and internal oblique muscles will be followed posteriorly until the layers of the thoracolumbar fascia appear as a bright hyperechogenic line. The quadratus lumborum muscle appears below to the latissimus dorsi muscle. While performing the quadratus lumborum block, "Shamrock sign" is identified; the transverse process of L4 appears as a stem whereas the three muscles psoas muscle, quadratus lumborum muscle and erector spinae appear as the leaves. A 22G (50mm) needle was inserted using an in-plane technique along the posterior edge of the ultrasound probe in the anteromedial direction. The needle tip was placed between the quadratus lumborum muscle and the Erector spinae muscle.
