Overview
Brief Summary
Patients experiencing pain after undergoing cardiac surgery may also experience prolonged immobilization, insufficient respiratory functions, and the inability to cough due to median sternotomy. Therefore, duration of mechanical ventilation, length of intensive care unit (ICU) stay, and length of hospital stay of these patients will increase significantly.
many facial plane blocks have been introduced as simple and safe intervention for thoracic wall anesthesia and analgesia. Parasternal intercostal nerve block (PSIB) is a "superficial block" which involves local anesthetic (LA) infiltration in the intercostal space around the sternum where the anterior branches of intercostal nerves exist.
Intraoperative LA administration under direct vision of the surgeon ensures adequate delivery of drugs and minimizes bleeding complication or inadvertent administration in blood vessels. Meanwhile, Preoperative administration of LA guided by ultrasound imaging has been used in variable surgical settings with noticeable success because of preemptive inhibition of noxious stimuli.
