Truncal Blocks: Thoracic Paravertebral Blocks
Paravertebral blocks are an older technique, which have regained popularity due to the increased safety of ultrasound assisted or live-time needle guided paravertebral blockade with or without catheter placement. Efficacious for both thoraco-abdominal and abdominal surgery, it and may have the same potency as thoracic epidural analgesia with greater haemodynamic stability. It can be unilaterally or bilaterally inserted; single-shot or continuously administered. Bilateral continuous blocks are required for open abdominal surgery. Pneumothoax and potential vascular injury are the most serious potential complications. Limiting catheter insertion to less than 3 cm within the paravertebral space reduces misplacement. Due to the efficacy and haemodynamic stability of this technique it may be well suited to enhanced recovery after surgery for major abdominal surgery.
