Sex: All

Ages: 7+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients greater than and equal to seven years of age
• Patients with traumatic acute distal radius/ulnar fractures with displacement that require reduction and immobilization with splinting
• Patients that receive distal radius hematoma blocks, including those who require additional pain control adjuncts if pain control is not adequate

Exclusion criteria

• Prisoners
• Pregnant women
• Patients with altered mental status/have impaired decision-making capacity.
• Patients with allergies to amide anesthetics

Trial design

Primary purpose: Supportive Care

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

96 participants in 2 patient groups

Study Intervention Group (Ultrasound)

Active Comparator group

Description:

The ultrasound probe will be used for real-time needle and hematoma localization using the linear probe. The hematoma block will then be performed with aseptic technique. The skin will be prepped with chlorhexidine. A 20-gauge needle will be inserted in-plane into the hematoma site. A small amount of blood will be aspirated to confirm placement and 5-10 mL of 1% lidocaine will be infiltrated.

Treatment:

Device: Ultrasound

Study Control Group (Landmark)

No Intervention group

Description:

The ultrasound probe will be in place on the patient's arm to maintain single blinding of the study. The ultrasound machine will not be used for needle and hematoma localization. The hematoma block will then be performed with aseptic technique. The skin will be prepped with chlorhexidine. A 20-gauge needle will be inserted in-plane into the hematoma site. A small amount of blood will be aspirated to confirm placement and 5-10 mL of 1% lidocaine will be infiltrated.
