Serratus plane block was first described in 2013 by Blanco and designed to primarily block
the thoracic intercostal nerves. And this block provides sufficient analgesia lateral
anterior and posterior part of thoracic wall.Increased use of ultrasound guidance for
regional anesthesia in recent years has led to definition of thoracic wall PECs blocks by
Blanco. The Serratus plain block (SPB), providing wider analgesia, with easier application
and less adverse effects than neuroaxial blocks, has been defined after these blocks and has
taken its place in the literature.In spite of the insufficient randomized clinical trials in
the literature, SPB has been reported for many cases such as thoracoscopy, shoulder
arthroscopy, breast surgery and axillary lymph node dissections, and the results are
promising. The aim of this study is to determine effectiveness of ultrasound guided bilateral
serratus plane block in patients undergoing breast reduction surgery.
Main outcome measures: The primary endpoint is postoperative opioid consumption.
Secondary endpoints are visual analogue pain scores, opioid related side effects.
