The aim of this study was to evaluate the effect of pectointercostal fascial plane block on regional haemodynamic parameters in patients undergoing cardiac surgery.

Perioperative pain management has become an important component of Enhanced Recovery After Surgery (ERAS) protocols in patients undergoing cardiac surgery. Pain is most intense in the first two days after cardiac surgery. Inadequate pain control has been shown to cause an increase in pulmonary complications due to inadequate mobility and coughing, an increase in sympathetic activation, an increase in myocardial infarction and thromboembolic events, delayed wound healing, and prolonged hospital and intensive care unit stay. Non-steroidal anti-inflammatory drugs (NSAIDs), paracetamol, opioids, epidural anesthesia and ultrasound-guided fascial plane blocks are widely used for pain management after cardiac surgery. The pectointercostal fascial plane (PIFP) block is an ultrasound-guided, superficial fascial plane block that can be applied as part of multimodal postoperative analgesia, especially after cardiac surgery. PIFB block has been shown to reduce postoperative analgesic consumption and improve pain scores not only in patients undergoing cardiac surgery but also in non-cardiac surgeries and thoracic procedures. The aim of this study was to evaluate the effect of PIFP block on regional haemodynamic parameters in patients undergoing cardiac surgery.
