Ultrasound-Guided Mid-Point Transverse Process to Pleura Block Versus Thoracic Paravertebral Block for Pain Management in Patients With Multiple Rib Fractures (A Prospective Randomized Double- Blinded, Non-inferiority Trial )
Sponsor: Assiut University
Summary
The aim of our study is to investigate whether the analgesic effect of MTPB is non inferior to that of TPVB in trauma patients with multiple rib fractures.

Mid point transverse to pleura block
TPVB and MTPB was performed at a spinal level midway between the uppermost and the lowest fractured rib, with the patient in a sitting position, and under complete aseptic conditions, a linear ultrasound probe (GE Healthcare-Logiq F6) will be placed oblique parasagittally 3 cm lateral to spinous process used to identify the transverse process, pleura, superior costotransverse ligament, and the paravertebral space at the target vertebral level. After skin and subcutaneous tissue infiltration with 2-3 mL of 2% lignocaine, an 18-gauge Touhy needle was inserted under ultrasound guidance until the needle tip reaches : * the midpoint between the transverse process and the pleura (group M). * the paravertebral space (group P). A bolus dose (0.3mL/kg) of plain bupivacaine 0.5% plus 8 mg of dexamethasone was injected after negative aspiration to blood and air.
