Overview
Brief Summary
This prospective, randomized, double-blind, parallel-group clinical trial within the Enhanced Recovery After Cardiac Surgery (ERACS) program compares postoperative analgesic effectiveness of bilateral erector spinae plane (ESP) block versus ESP combined with superficial parasternal intercostal plane (SPIP) block in adult patients undergoing elective cardiac surgery via median sternotomy.
Detailed Description
Rationale: Effective multimodal, opioid-sparing analgesia is crucial in cardiac surgery to enhance recovery and reduce pulmonary and cognitive complications. Neuraxial techniques (e.g., epidural) carry increased hematoma risk under anticoagulation; hence, fascial plane blocks like ESP and SPIP are safer alternatives.
Methodology: Randomized (ResearchRandomizer.org), 1:1 allocation, opaque sealed envelopes. ESP and SPIP performed under ultrasound guidance at standardized doses and locations.
Blinding: Patients and postoperative evaluators are blinded; block-performing anesthesiologist unblinded but uninvolved in assessment.
Follow-up: 0-72 hours after extubation with predefined time points for VAS, RASS, and Nu-DESC evaluations.

Masking Description
The study will be double-blind, meaning neither the researchers nor the participants will know which treatment group they belong to, ensuring unbiased outcome assessment.

Outcomes
Primary Outcomes
VAS (resting)
Time Frame: Up to 72 hours post-extubation
Average of VAS scores at 0, 1, 6, 12, 24, 48, and 72 hours after extubation (t=0). Lower scores indicate better analgesia. Pain was assessed using the 0-10 Visual Analog Scale (VAS). Pain severity was classified as follows: 0 = no pain, 1-3 = mild pain, 4-6 = moderate pain, 7-10 = severe pain. Rescue analgesia was administered when VAS score was \> 4.
Secondary Outcomes
- VAS (movement)(0-72 hours)
- Total rescue tramadol use (mg)(0-72 hours)
- Time to first rescue analgesic (min)(0-72 hours)
- Delirium incidence (Nu-DESC ≥ 2)(12, 24, 48, 72 hours)
- RASS score profile(0, 12, 24, 48, 72 hours)
