Pediatric anesthesia & critical care
Ultrasound guidance does not improve local anesthetic distribution in suprazygomatic maxillary nerve blocks in pediatric patients: a clinical, randomized, controlled, observer-blinded, crossover MRI trial
Authors' conclusion
Appropriate pain management for cleft palate repair can be achieved without the availability of imaging guidance.
Study context
- Population
- Pediatric patients scheduled for cleft palate repair receiving bilateral suprazygomatic maxillary blocks
- Participants
- 20 patients
- Comparison
- Ultrasound-guided vs landmark-based suprazygomatic maxillary nerve block
- Primary endpoint
- Local anesthetic spread to the pterygopalatine fossa with contact to the maxillary nerve on MRI (successful block)
Methodological detailsobserver-blinded, crossover, bilateral within-patient randomisation
- Observer-blinded
- Crossover
- Bilateral within-patient randomisation
Primary result
As reported in the abstract
Successful block (spread to pterygopalatine fossa with maxillary nerve contact)
P = 0.56
Safety
Adverse events or complications during or after the block procedures
- No adverse events or complications observed
