Abstract

Pain management after spine surgery is challenging and usually not sufficient. Most patients suffer from severe postoperative pain. Numerous studies have demonstrated the effectiveness of various regional anesthetic techniques in postoperative pain management. In recent years, thoracolumbar interfascial plane block (TLIP) has become widely used for perioperative analgesia during lumbar spine surgeries. It is a type of ultrasound-guided plane block, during which a local anesthetic is injected into the fascial plane between the multifidus and longissimus muscles, with the aim of blocking the dorsal rami of the thoracolumbar nerves. TLIP block was first proposed by Hand et al. in 2015. The aim of this study is to review the scientific publications regarding the use of TLIP block in lumbar spine surgery in the most popular electronic databases, such as PubMed, Scopus, Google Scholar, Web of Science, and comparing lumbar spine surgeries with and without TLIP block according to the following criteria: postoperative pain intensity, postoperative analgesic requirement, intraoperative opioid use, incidence of postoperative nausea and vomiting, comparison with other regional anesthesia methods. Analysis of the reviewed literature shows that TLIP block in lumbar spine surgery reduces the requirement of perioperative analgesics, decreases the intensity of postoperative pain up to 24 hours postoperatively, reduces the frequency of postoperative nausea and vomiting, therefore, is an effective method and can be used in daily practice. At the same time, almost all researchers consider that obtained data quality is low and that more studies with a larger number of patients and a longer duration are needed to statistically confirm the obtained data. In particular, studies are needed to determine whether TLIP block is sufficiently effective compared to other regional anesthesia methods, especially erector spinae plane block (ESP), whether TLIP block reduces the incidence of chronic pain syndrome, whether it affects the duration of surgery, postoperative intensive care unit treatment and length of hospital stay, whether TLIP-block reduces intraoperative blood loss, whether it is possible to prolong and enhance the effect of TLIP block with adjuvants, in particular dexamethasone and dexmedetomidine. Thoracolumbar interfascial plane block (TLIP) is a promising method for perioperative analgesia, reduction of analgesic use and postoperative complications in lumbar spine surgery, however, further studies are needed to determine its effectiveness and optimal application methods.
