TI  - Sympatholytic Effect of the High Thoracic Erector Spinae Plane Block.
PG  - 43-49
AB  - BACKGROUND: The erector spinae plane block (ESPB), which was introduced for the 
      management of thoracic pain, is a technically easy and relatively noninvasive 
      ultrasound (ULSD)-guided technique. Although the ESPB is used widely in variable 
      clinical situations, its sympatholytic effect has never been studied. OBJECTIVES: 
      The purpose of this study is to demonstrate the sympatholytic effect of the high 
      thoracic ESPB by comparing the blocked and unblocked sides of patients' upper 
      extremities, using the changes in the perfusion index (PI). STUDY DESIGN: 
      Prospective, single-group, and open-label study. SETTING: The study was carried 
      out in the pain clinic of a tertiary university hospital. METHODS: This study 
      included 47 patients with upper extremity pain and various diseases who received 
      T2 or T3 ESPBs using 20 mL of 0.2% ropivacaine. For the evaluation of the 
      sympatholytic effect, measurements were taken on the numeric rating scale (NRS), 
      the neck disability index (NDI), and the PI. RESULTS: The PIs of the blocked 
      sides demonstrated significant increases at 10, 20, and 30 minutes compared to 
      the PIs of the baseline and unblocked sides (P < 0.001). The PI ratio at 10 
      minutes was 2.74 +/- 1.65, which was the highest value during the measurement 
      period. Until 30 minutes after the ESPB, the PI ratio was significantly higher in 
      the blocked side than in the unblocked side. During the study period, significant 
      reductions in NRS and NDI scores were found irrespective of disease entity. 
      LIMITATION: The period of PI measurement was only 30 minutes, so we could not 
      determine the time point when the PI returned to the baseline value. CONCLUSION: 
      The high thoracic ESPB was effective in relieving upper extremity pain in diverse 
      disease entities, and the PIs of patients' blocked sides demonstrated significant 
      increases over the baseline value and contralateral unblocked sides.
