Successful cutaneous sensory blockade following single-injection and double-injection techniques of ultrasound-guided superficial parasternal intercostal plane block: a randomized clinical trial
Primary resultResult — go to the resultRelative risk 1.6 95% CI 1.2–2.0Authors' conclusion
Compared with single injection, double injections of superficial parasternal blocks provided more reliable coverage of the T2-T6 dermatomes, crucial for median sternotomy. However, no differences were observed in intraoperative hemodynamic effects or postoperative pain control after cardiac surgery.
Study context
- Population
- Cardiac patients undergoing median sternotomy; 40 mL of 0.25% bupivacaine with epinephrine 5 µg/mL and dexamethasone 10 mg
- Participants
- 70 patients
- Comparison
- Double injections vs Single injection
- Primary endpoint
- Successful block (sensory loss in the T2-T6 dermatomes)
