[Perioperative pain therapy in minimally invasive thoracic surgery]

Thoracic surgery is often associated with severe postoperative pain levels. Even though these are less pronounced in thoracoscopic approaches, mechanical irritation, compression or injury of intercostal nerves and placement of chest tubes can cause pain levels, which must be treated. An adequate pain therapy in thoracic surgery is essential as insufficient inspiration due to inadequate analgesia may result in postoperative complications. Epidural anesthesia was considered the gold standard in thoracotomy for a long time. For video-assisted thoracoscopy, however, it is sometimes no longer recommended due to its benefit-risk ratio. Alternative thoracic blocks are the paravertebral block, the erector spinae plane block and the serratus anterior block, for which research has found heterogeneous results.This article summarizes the current recommendations for perioperative management of thoracoscopic surgery and gives an overview of the PROSPECT recommendations as well as the current Association of the Scientific Medical Societies in Germany (AWMF) guidelines for perioperative and postoperative pain therapy. In particular, individual regional anesthesia techniques and their current evidence are reviewed.
