Bolus intertransverse process block and continuous erector spinae plane block for perioperative analgesic management of video-assisted thoracoscopic surgery - Three cases report.

ABSTRACT

BACKGROUND: Common regional anesthesia approaches for video-assisted thoracoscopic surgery (VATS) include paravertebral block (PVB) and erector spinae plane block (ESPB). PVB is considered a deep nerve block which is contraindicated in antithrombotic therapy. ESPB is effective when administered as a bolus, as well as continuously. However, the recently proposed intertransverse process block (ITPB) ensures more effective diffusion of the local anesthetic into the paravertebral space. CASE We report cases of three patients who received bolus ITPB (costotransverse foramen block and mid-point transverse process-to-pleura block in one and two cases, respectively) combined with continuous ESPB when a deep nerve block could not be administered. Opioids were not required postoperatively, and all postoperative numerical rating scale scores (0-10) at rest were maintained below 4. CONCLUSIONS: The combination of bolus ITPB and continuous ESPB may be an alternative analgesic method when deep nerve blocks are contraindicated in VATS.
