Comparison of Conventional and Retroclavicular Approaches for Ultrasound-guided Infraclavicular Brachial Plexus Block

Forearm and hand surgeries are among the most frequently performed surgical interventions both in trauma patients and electively.In these procedures, alternative anesthesia methods such as general anesthesia, regional intravenous anesthesia, regional peripheral nerve blocks and local anesthesia are available.

Peripheral nerve blockade can be used for anesthesia and analgesia.This method allows patients to undergo surgery without general anesthesia and increases patient satisfaction by providing effective analgesia in the postoperative period.

The aim of this study was to compare the conventional and retroclavicular approaches to infraclavicular block in patients undergoing forearm and hand surgery.

Inclusion criteria

  • Patients 18-80 years of age
  • Those with ASA score II-III
  • Those with a body mass index (BMI) >30
  • Patients who are suitable for forearm and hand surgery under regional anesthesia in the operating room

  • Patients who want to have surgery under general anesthesia
  • Patients in whom regional anesthesia is contraindicated

Treatment and study plan

Conventional approach to infraclavicular block

Procedure

Conventional approach to infraclavicular block will be performed on the patients using 20 ml of 0.5% bupivacaine 5ml of %2 lidocaine under ultrasound guidance.

Retroclavicular approach to the infraclavicular block

Procedure

Retroclavicular approach to the infraclavicular block will be performed on the patients using 20 ml of 0.5% bupivacaine 5ml of %2 lidocaine under ultrasound guidance.

Primary outcomes

  1. Block Performance Time

    Time frame: During regional anesthesia

    Total block performance time (from skin puncture to needle removal) will be recorded

Secondary outcomes

  1. Pain Score

    Time frame: Up to 24 hours

    Pain will be assessed using a visual analog scale from 0 mm (no pain) to 100 mm (worst pain) at rest and when coughing. Pain assessment will be made at 0, 1, 6, 12, 18, and 24 hours after surgery.

  2. Patient Satisfaction

    Time frame: 1 day

    Quality of recovery-15 (QoR-15) score was used as the satisfaction score. The patient-reported Turkish QoR-15 score includes 15 questions that evaluate the patient's postoperative recovery. The QoR-15 score is grouped under two groups, A and B. A high QoR-15 score, a score between 0 (poor) and 10 (excellent) for each item, and a total score of 150 indicate better quality of recovery.
