Study summary

The pain after shoulder rotator cuff repair surgery is severe due to the inflammatory reaction of tendon repair. Severe pain will reduce the patient's shoulder range of motion and delay functional recovery. The use of powerful analgesics for pain relief may also increase the chance of opiate analgesic-related side effects. Brachial plexus block with local anesthetic is widely used for pain control at the acute stage after shoulder arthroscopic surgery, but the maintenance time is often limited. Ropivacaine is a local anesthetic commonly used for brachial plexus block, and its half-life time is 11.8 hours. Clinical studies showed that using ropivacaine plus adjuvants such as dexamethasone or dexmedetomidine for brachial plexus block significantly extended the block duration, reduced postoperative pain, and reduced the use of opiate analgesics. However, the safest and most effective combination of local anesthetics remains unresolved.

This trial aims to evaluate and compare the effects of brachial plexus block using dexamethasone and dexmedetomidine combined with ropivacaine on postoperative pain control and functional recovery after arthroscopic rotator cuff repair surgery.

Read the detailed description

Shoulder joint surgery is an orthopedic surgery recognized to cause severe postoperative pain. The pain after shoulder rotator cuff repair surgery is severer than other shoulder joint surgeries due to the inflammatory reaction of tendon repair. Severe pain will reduce the patient's shoulder range of motion and delay postoperative functional recovery, and the use of powerful analgesics for pain relief may also increase the chance of side effects related to opiate analgesics. Therefore, postoperative pain control has become an important clinical issue.

Brachial plexus block with local anesthetic is widely used for pain control at the acute stage after shoulder arthroscopic surgery, but the maintenance time is often limited. Ropivacaine is a local anesthetic commonly used for brachial plexus block, and its half-life time is 11.8 hours. Clinical studies showed that using ropivacaine plus adjuvants such as dexamethasone or dexmedetomidine to perform brachial plexus block significantly extended the block duration, reduced postoperative pain, and reduced the use of opiate analgesics. Brachial plexus block with low-dose dexmedetomidine plus ropicavaine significantly prolonged analgesia by 4 hours (14 hours vs. 10 hours) compared to ropicavaine alone, and reduced the dose of opiate analgesias in the first 24 hours after surgery. Compared to ropicavaine only, low-dose dexamethasone plus ropivacaine effectively extended the analgesic duration by 8 hours (19.7 hours vs. 11.8 hours) and reduced the dose of opioid analgesics within 36 hours after surgery (6.5mg versus 2mg). Meanwhile, continuous administration of ropicavaine through a catheter for brachial plexus block can maintain effective analgesia. However, the safest and most effective combination of local anesthetics remains unresolved.

This trial aims to evaluate and compare the effects of brachial plexus block using adjuvants dexamethasone and dexmedetomidine combined with ropivacaine on postoperative pain control and functional recovery following arthroscopic rotator cuff repair surgery. Specifically, we will examine the effect of dexamethasone or dexmedetomidine alone, and in combination, on the duration of the analgesic effect of ropivacaine.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 20, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
