Ultrasound-Guided Supraclavicular Brachial Plexus Blocks Performed by Pediatric Emergency Medicine Physicians for Painful Orthopedic Procedures in a Pediatric Emergency Department-A Case Series

Building Blocks-A Block-by-Block Approach to Better Emergency Care in Children

OBJECTIVE

We describe a case series of regional nerve blocks, which comprise an adapted framework for the pediatric emergency setting and were performed by pediatric emergency medicine physicians.

METHODS

A case series of 8 different ultrasound-guided nerve blocks and 1 anatomical block, performed in 11 pediatric patients, aged 7 weeks to 17 years.

RESULTS

All blocks resulted in adequate analgesia. No procedural complications were observed.

CONCLUSION

We describe a set of nerve blocks performed by emergency medicine physicians in the pediatric population in an ED setting. In suitable settings, this is a safe and effective tool for procedural analgesia or for pain management. In such cases, performing an ultrasound-guided nerve block in the ED is a viable alternative for repeated doses of opiates, deep procedural sedation, or the operating theater. We propose this set of regional anesthesia procedures as a pediatric-adapted toolkit for the emergency physician to be performed in children in the ED setting. Adopting this set of procedures ensures better and safer care for children and provides a training framework for pediatric ED physicians.

Ultrasound-guided supraclavicular block versus Bier block for emergency reduction of upper limb injuries: a protocol for an open-label, non-inferiority, randomised controlled trial

BACKGROUND

Closed reduction of upper limb fractures and/or dislocations are common in the emergency department (ED), which involves physically re-aligning the injured part prior to immobilisation. As this is painful, numerous techniques are available to provide regional anaesthesia to ensure patient tolerance. A Bier block (BB) is typically performed as part of routine care. An alternative technique gaining interest in the ED is ultrasound-guided supraclavicular block (UGSCB), which involves injecting local anaesthetic around the brachial plexus at the supraclavicular fossa under ultrasound guidance. It is unclear whether UGSCB is effective and safe when performed in the ED.

METHODS

SUPERB (SUPraclavicular block for Emergency Reduction versus Bier block) is a prospective open-label, non-inferiority randomised controlled trial that compares the effectiveness of UGSCB versus BB for closed reduction of upper limb fractures and/or dislocations. Adult patients presenting with an upper limb fracture and/or dislocation that requires emergent closed reduction in the ED will be eligible. After screening, participants will be randomised to either UGSCB or BB. Once regional anaesthesia is obtained, closed reduction of the injured part will be performed and appropriately immobilised. The primary outcome is maximal pain experienced during closed reduction measured via a visual analogue scale (VAS). Secondary outcomes include baseline and post-reduction pain, patient satisfaction, total opioid requirement in ED, ED length of stay, adverse events and regional anaesthesia failure.

DISCUSSION

Existing evidence suggests UGSCB is effective when performed in the operating theatre by trained anaesthetists. SUPERB will be the first randomised controlled trial to elucidate the effectiveness and safety of UGSCB in the ED. The findings have the potential to provide an alternative safe and effective option for the management of upper extremity emergencies in the ED.
