Impact of High Thoracic Paravertebral Block on Diaphragmatic Function: a Prospective Study

Sponsor: Ciusss de L'Est de l'Île de Montréal

Summary

The high thoracic paravertebral block is a regional anesthesia technique commonly used for oncologic breast surgery. Local anesthetic is injected into the paravertebral space to provide anesthesia and pain relief. Case reports suggest that cephalad spread of local anesthetic may occasionally affect the phrenic nerve and lead to temporary hemidiaphragmatic dysfunction, but the incidence of this complication is unknown. The goal of this prospective interventional study is to evaluate the impact of high thoracic paravertebral block on diaphragmatic function in patients undergoing unilateral oncologic breast surgery. Diaphragmatic function will be assessed using ultrasound before and after the block. The study will also evaluate postoperative pain, opioid consumption, respiratory symptoms, and other postoperative outcomes.
