ABSTRACT
BACKGROUND: Regional anesthetic techniques are applied in cardiac surgery to improve postoperative pain and accelerate recovery. Pecto-intercostal fascial block (PIFB) combined with rectus sheath block (RSB) has been proved to provide ideal analgesia for cardiac surgery, but the effects of combing regional anesthetic techniques on postoperative recovery are uncertain.
METHODS: This is a prospective and randomized controlled trial at Fuwai Hospital from 1 June 2024 to 3 July 2024. Eighty patients undergoing elective cardiac surgery via cardiopulmonary bypass were randomized at a 1:1 ratio to be allocated in the intervention group (PIFB combined with RSB) or control group (without regional blocks). The primary outcome was the global score of the 15-item quality of recovery (QoR-15) questionnaire at 24 h after surgery. Secondary outcomes included QoR-15 at 72 h, postoperative pain scores, time to extubation, length of stay, medical expenses in hospital and postoperative morbidities.
RESULTS: The QoR-15 global score at 24 h after cardiac surgery was 122.35 ± 6.71 in the intervention group vs 115.30 ± 5.90 in the control group (P < .001). The proportion of patients experiencing better quality of recovery (Qor-15 ≥ 118) was higher in the intervention group (77.5% vs 55%, P = .033). Postoperative pain scores were 1.90 ± 0.18 in the intervention group compared to 2.95 ± 0.99 in the control group (P = .027) at 24 h. Time to extubation was earlier in the intervention group (274.40 ± 98.36 vs 741.28 ± 93.82 min, P < .001). There were no statistically differences in Qor-15 at 72 h and other recovery outcomes.
CONCLUSION: The administration of PIFB combined with RSB could improve quality of recovery and relieve postoperative pain for patients following cardiac surgery. Key message What is already known on this topic Previous studies have demonstrated that ultrasound-guided nerve blocks effectively reduce postoperative pain in cardiac surgery patients. However, whether these techniques further enhance overall postoperative recovery remained unclear. What this study adds This trial revealed that ultrasound-guided nerve blocks improved postoperative QoR-15 scores, and combined regional techniques further improved recovery without compromising analgesia. How this study might affect research, practice, or policy The findings support applying combined nerve blocks into enhanced recovery protocols for cardiac surgery, offering evidence to optimize postoperative analgesia strategies.
