Effect of Continue RISS Block in Thoracotomy

Study Overview
=================
Brief Summary
-----------------
Thoracotomy is one of the most painful surgery. Acute postoperative pain increases postoperative morbidity and prolongs hospital stay and also may lead to developing a chronic pain syndrome. This study aimed to assess the efficacy of continuous rhomboid intercostal and subserratus plane (RISS) block by inserting a catheter under direct vision for controlling acute thoracotomy pain.

Detailed Description
-----------------
Before the closure of the thoracotomy, the surgeon will place two catheters through a Tuohy needle into fascial planes for continue RISS block. First catheter tip will be place towards the interfascial planes between the rhomboid major and intercostal muscles and the second catheter tip will be place in subserratus fascial plane. Continue local anesthetics will be injected through the catheters for 48 hours.
