Serratus anterior and pectoralis plane blocks for robotically assisted mitral valve repair: a randomised clinical trial
Authors' conclusion
Serratus anterior and pectoralis plane blocks did not improve postoperative analgesia, cumulative opioid consumption, or respiratory mechanics during the initial 3 days after robotically assisted mitral valve repair.
Study context
- Population
- Adults scheduled for robotically assisted mitral valve repair
- Participants
- 194 adults
- Comparison
- Pectoralis II + serratus anterior plane blocks vs routine analgesia
- Blocksn = 98
- Routine analgesian = 96reference
- Primary endpoint
- Overall benefit analgesia score (OBAS), total over postoperative days 1-3
- Follow-up
- Postoperative days 1-3
Primary result
As reported in the abstract
Total OBAS over POD 1-3
- Treatment effect on total overall benefit analgesia score (OBAS): median difference
- 0.08 (95% CI: −0.50 to 0.67; P=0.69)
- Treatment effect on total OBAS: estimated ratio of geometric means
- 0.98 (95% CI: 0.85-1.13; P=0.75)
- Time-by-treatment interaction: none
- P=0.67
Further findings
Cumulative opioid consumption
- No evidence of a treatment effect
Respiratory mechanics
- No evidence of a treatment effect
Average daily pain scores · Each postoperative day
- Similarly low in both groups
