Brief Summary

Ultrasound-guided thoracolumbar interfascial plane block (TLIP)was first described in 2015 by Hand et al which also target the dorsal rami of the thoracolumbar nerves as they pass through the paraspinal musculature(between the multifidus muscle (MF) and the longissimus muscle (LG)). The block was performed bilaterally at the level of L3 and they reported a reproducible area of anesthesia to pinprick in a mean (SD) area covering 137.4 (71.0) cm2 of the lower back (including the midline) after 20 minutes of the block. This procedure has subsequently been modified by Ueshima H et al in 2016 by targeting the injection in the plane between the longissimus and iliocostalis muscles (mTLIP) which helps avoiding the spread of local anesthetics to the ventral ramus and neuraxial space, thus, the modified TLIP block is considered to be a more refined version of the original TLIP block and safer and easier to perform. There are limited number of studies investigating the analgesic efficacy of mTLIP block however, no previous study has demonstrated the ideal local anesthetic volume for this block in lumber spine surgery. Moreover, this technique is considered new regional anesthetic techniques and so both of them should be involved in further studies, on the other hand the comparison between both of them at the same study wasn't discussed before, and so we will proceed at this study.

EXPERIMENTAL

patients will receive single shot of bilateral modified thoracolumbar interfascial plane block at the mid-level of the operative intervention with 20 ml 0.25%bupivacaine (10 ml on each side).

Procedure: Thoracolumbar interfascial plane block (TLIP)TechniqueProcedure: Anesthetic ManagementDrug: Bupivacaine Injection 10ml

mTLIP20

EXPERIMENTAL

patients will receive single shot of bilateral modified thoracolumbar interfascial plane block at the mid-level of the operative intervention with 40 ml 0.25%bupivacaine (20 ml on each side).

Procedure: Thoracolumbar interfascial plane block (TLIP)TechniqueProcedure: Anesthetic ManagementDrug: Bupivacaine Injection 20ml

Interventions

A curvilinear array ultrasound probe (Siemens ACUSON X300 Ultrasound System) will be placed at the targeted lumbar level.The corresponding spinous process and interspinal muscles will be identified, and the probe will be slided laterally to identify the longissimus muscle and iliocostalis muscle. Under ultrasound guidance, A 38-mm 22-gauge (22-G, 50-mm 'Stimuplex; BBraun, Melsung, Germany) regional block needle will be advanced in plane to the ultrasound beam in a medial to lateral orientation through the belly of longissimus muscle toward the iliocostalis muscle. Hydro-dissection with 2-3 ml of isotonic saline solution will confirm the correct needle tip position and, after negative aspiration, 0.25 % bupivacaine will be injected slowly whilst carefully monitoring the spread of local anesthetic into the fascial plane between the longissimus and iliocostalis muscles. The same procedure will be repeated on the contralateral side.

mTLIP10mTLIP20

Induction: Induction of general anesthesia will be performed using a regimen of IV 2 μg/kg fentanyl and propofol IV 2 mg /kg. Tracheal intubation will be facilitated using 0.5 mg/kg IV of atracurium. Maintenance: Anesthesia will be maintained with inhaled isoflurane 0.8% in oxygen enriched air (FiO2=0.5). Maintenance doses of 0.1 m\\kg atracurium will be provided every 30 minutes. Then the patient will be placed in prone position.
