Ultrasound-guided single shot supraclavicular block for shoulder arthroscopy

With the use of ultrasound in regional anesthesia supraclavicular block has gained a "new" popularity. Ultrasound giudance makes it easier to perform and helps in avoiding unintentional puncture of vascular structures or pleura. We propose this method to be a suitable choice for such procedures. After the approval of the local human ethics commitee, we identified using operating room records forty healthy patients who underwent shoulder surgery in supraclavicular block. Block was performed with 25ml 0.5% levobupivacaine, while low frequency nerve stimulator was used with ultrasound. All patients were given sufentanyl 5μg iv. before performing the block. Time needed to perform the block, onset of the sensory blockage, intraoperative and postoperative pain (using visual analog scale), need for additional analgesia and patient satisfaction were measured. Time needed to perform the block was 15±5 min, onset of of the sensory block was 15 ± 8min. There was no statistical difference between intraoperative and postoperative VAS (intraoperative and postoperative VAS were 1.5±0.6 and 1.9±0.5, respectively). Five patients needed additional sedatives (midazolam boluses 5 mg iv). Analgesic effect lasted 18±2.4 hours after the surgery. All patients were satisfied with such anesthetic method. Ultrasound-guided supraclavicular block provides sufficient anesthesia and postoperative analgesia for shoulder arthroscopy. Single shot technique is suitable for patients who are discharged from hospital the next day. Using ultrasound guidance we can perform the block fast and accurate with reduced volume. It has fast onset time and high patient satisfaction level.
