PATHOS Study Pain Assessment in Thoracic Oncologic Surgery

PATHOS Study Pain Assessment in Thoracic Oncologic Surgery: a Prospective Randomized Trial on Pain Management After Video Assisted Major Lung Resections.

A randomized prospective trial to assess whether the use of loco regional anesthesia as adjuvant analgesic therapy is more effective of intravenous analgesia only.

A prospective randomized trial comparing intravenous analgesia alone and in association with loco regional anesthesia consisting in a homolateral Serratus Plan Block (SPB). Loco regional blockade of the serratus is further examined by allocating the patients to two different approaches: the block being performed under US guidance by the Anesthesiologist before the beginning of the procedure, or under direct visualization, by the operating surgeon, before entering the pleural cavity.
