Ultrasound-guided Infraclavicular Block With Lidocaine or Ropivacaine for Closed Reduction of Distal Radius Fractures

Effect of Ultrasound-guided Lateral Infraclavicular Brachial Plexus Block With Lidocaine or Ropivacaine for Closed Reduction of Distal Radius Fractures - A Randomized Controlled Non-inferiority Trial

To investigate the feasibility of the lateral infraclavicular plexus brachialis (LIC) block for acute closed reduction of distal radius fractures, the investigators will compare the pain-relieving and muscle-relaxing properties of the LIC block with short- and long-acting local anesthetics in different concentrations but at the same volume. In addition to motor and sensory blockade during repositioning, feasibility will also be assessed by other patient-related and block-related factors, as well as by factors related to the repositioning and plastering procedure.

Inclusion Criteria:

Patients who have given written informed consent to participate in the study after having understood it, as well as:

• Having a distal radius fracture requiring closed reduction

Exclusion Criteria:

Patients who meet one or more of the following criteria will be excluded from participating in the study:

• BMI > 40 kg/m2
• Weight < 50 kg
• Age < 18 years
• American Society of Anesthesiologists (ASA) physical status classification system grade >3
• Allergy to experimental drugs
• Patients who cannot cooperate with the examinations or treatment
• Patients who do not understand or speak Danish
• Patients with peripheral or central neurological disease or nerve damage with neurological effect on the upper extremity, where closed reduction is required
