    Objective: This study aimed to investigate the effects of ultrasound-guided bilateral parasternal block (PSB) combined with rectus sheath block (RSB) on postoperative recovery quality in patients undergoing median sternotomy for cardiac surgery.Methods: Eighty patients were randomly assigned to either the intervention group (receiving PSB+RSB, n=40) or the control group (not receiving PSB+RSB, n=40). The primary outcome was opioid consumption within the first 24 hours postoperatively. Secondary outcomes included Visual Analog Scale (VAS) pain scores and various surgery and recovery-related parameters.The intervention group showed significantly reduced opioid consumption in the first 24 hours postoperatively compared to the control group (P<0.05), though no significant difference was observed at 48 hours postoperatively. VAS pain scores at extubation and at 12, 24, and 48 hours post-extubation were significantly lower in the intervention group (P<0.05).The intervention group also demonstrated superior Quality of Recovery-15 (QoR-15) scores at all observed time points compared to the control group (P<0.05), with no block-related adverse events. There were no significant differences in surgical and recovery-related parameters between the groups.Ultrasound-guided bilateral PSB combined with RSB effectively enhances postoperative analgesia and the quality of recovery in patients undergoing median sternotomy for cardiac surgery. The application of ultrasound-guided bilateral parasternal block combined with rectus sheath block in median sternotomy cardiac surgery offers a new pain management strategy that is both safe and highly effective. This approach reduces postoperative analgesic requirements and improves recovery quality for cardiac surgery patients.
