Study summary

The purpose of this study is to compare different types of local anesthesia-a supracondylar radial nerve block, a hematoma block, or a combination of the two-for reducing pain in people with a broken wrist (distal radius fracture). This is being done to find out which method provides better pain relief after the injury and during treatment in the emergency room.

Read the detailed description

This study is testing different ways to provide pain relief before reducing a broken wrist. Participants will receive one of three techniques: (1) a nerve block where a doctor injects lidocaine near the radial nerve under ultrasound guidance; (2) a hematoma block where a doctor injects lidocaine into the area where the bone broke; or (3) both the nerve block and the hematoma block. Patients will be asked how much pain they feel before the numbing, after the numbing, and after the wrist is reduced.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • 18 years of age or older
  • Patients admitted to the ECC with a distal radius fracture requiring closed reduction
  • Patient must be willing and able to provide to the study

Exclusion criteria

Exclusion Criteria:

  • Under 18 years of age
  • Pregnant
  • Prisoner
  • Allergy to lidocaine
  • Patients unable to provide and/or perform study-related activities
  • Patients undergoing procedural sedation
  • Patients may be excluded at the discretion of the investigator based on their clinical judgment, if the participant no longer meets criteria, and/or if the health or safety of the patient may be impacted by taking part in the study.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Supracondylar radial nerve blocks

    Lidocaine injection given near the radial never under ultrasound guidance

    Procedure: Supracondylar radial nerve block

  • Experimental
    Hematoma blocks

    Injecting analgesia into the hematoma that forms surrounding the wrist fracture

    Procedure: Hematoma block

  • Experimental
    Combination of supracondylar radial nerve block and hematoma block

    Supracondylar radial nerve block given first followed by hematoma block

    Procedure: Combination of blocks

Interventions

  • ProcedureSupracondylar radial nerve block

    Supracondylar radial nerve blocks given at the radial nerve not as the same location of the fracture site, prior to fracture reduction.

  • ProcedureHematoma block

    Injection of analgesia into the hematoma that forms surrounding the wrist fracture.

  • ProcedureCombination of blocks

    Supracondylar radial nerve block given first, followed by hematoma block, before fracture reduction.

What researchers measure

Primary outcomes

  1. Pain levels comparison

    Comparing pain levels among patients who are undergoing a wrist fracture reduction. Measured on a scale of 0-10, 0= no pain to 10= worst pain. Pain will be measured at (1) baseline, (2) after administering the assigned pain block (s), and after the (3) fracture reduction.

    Time frame: Pain will be measured at (1) baseline, (2) after administering the assigned pain block(s), and after the (3) fracture reduction.

Secondary outcomes

  1. Amount of opioid medication needed to control pain.

    The amount of opioid prescribed, if any, will be collected and recorded for comparison during patient's time in emergency room.

    Time frame: Opioid medication prescribing will be assessed at baseline, time of admission to the emergency room, until the patient is discharged and they are no longer active in the study.

  2. Number of patients requiring conscious sedation.

    The need for conscious sedation among patients undergoing wrist fracture reduction in emergency care center will be recorded and monitored for comparison between groups.

    Time frame: Patients will be monitored for need of conscious sedation from baseline, time of enrollment in the study, until discharge from the emergency room, when they are no longer active in the study.

  3. Adverse Events Monitoring

    Adverse events associated with any of the blocks that are administered to patients undergoing a wrist fracture reduction in the emergency care center will be identified, monitored, and recorded for reporting.

    Time frame: From baseline, time the patient is admitted and enrolled into the study, until the patient is discharged and no longer active in the study.
