Early Versus Late Paravertebral Block for Analgesia in Video-Assisted Thoracoscopic Lung Resection. A Double-Blind, Randomized, Placebo-Controlled Trial.

Objectives: Paravertebral local analgesia is effective in providing pain relief after video assisted thoracoscopic surgery. This randomized, double-blind pilot clinical trial investigated the effect of early perioperative delivery of paravertebral local analgesia to reduce postoperative pain after video assisted thoracoscopic lung resection and the feasibility of a larger trial.

Design: Double-blind, randomized, placebo-controlled trial.
