Summary
OPEN CARDIAC SURGERY may cause severe postoperative pain and promote a high risk of chronic
pain if not treated adequately, that is caused by multiple factors; sternotomy,
costotransverse and costovertebral joint distensions, opening of the pericardium, internal
mammarian artery harvesting, surgical manipulation of the parietal pleura, chest tube
insertion and other musculoskeletal trauma that occurs during surgery.
Adequate analgesia is important not only for patient comfort, but for weaning from ventilator
and prevention of respiratory complications. Opioids are used to provide analgesia, but they
are associated with significant side effects which include sedation, respiratory depression,
nausea, and vomiting.
Severe sternotomy pain in cardiac surgery has been reported in up to 49% of patients at rest
and 78% at movement. Of the various options for postoperative pain relief in cardiac surgery,
we have chosen an ultrasound-guided transversus thoracic muscle plane (TTP) block versus sham
block performed by the anesthesiologist.
Transversus thoracic muscle plane (TTP) block and The pecto-intercostal fascial plane block
can block multiple anterior branches of the intercostal nerves (T2 to 6), which dominate the
internal mammary region with a single injection bilaterally.
