Summary
Ultrasound (US)-guided peripheral nerve blocks have been used increasily due to the
advantages of ultrasound in anesthesia practice. TLIP block is one of these nerve blocks
performed under US guidance. In this technique, local anesthetic solution is injected between
the multifidus and logissimus muscles nearly at the level of the 3rd lumbar vertebra and
targets the dorsal rami of the thoracolumbar nerves. However, the visualisation of this
technique may be difficult under US guidance. Therefore, modified-TLIP (mTLIP) block was
defined as a new approach. It has been reported that mTLIP block may provide effective
analgesia management after lumbar spine surgery.
The ultrasound (US) guided erector spina plane block (ESPB) is a novel interfacial plan block
defined by Forero et al. at 2016. Visualization of sonoanatomy with US is easy, and the
spread of local anesthesic agents can be easily seen under the erector spinae muscle. Thus,
analgesia occurs in several dermatomes with cephalad-caudad way. It has been reported that
ESPB provides lumbar analgesia at T10-12, L3. The aim of this study is to compare US-guided
mTLIP block and ESPB pain management after multi-level lumbar spinal instrumentation surgery.
