Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you have a history of chronic pain with daily opioid use, you may not be eligible to participate.

What data supports the effectiveness of the treatment Continuous Interscalene Brachial Plexus Block with Dexmedetomidine and Ropivacaine for shoulder pain?

Continuous interscalene brachial plexus block is effective for pain relief after shoulder surgery, and adding dexmedetomidine can prolong the duration of pain relief. Ropivacaine is effective in blocking pain with potentially fewer respiratory side effects compared to other anesthetics.12345

Is the combination of Dexmedetomidine and Ropivacaine safe for use in humans?

Research indicates that Ropivacaine is generally safe with a lower risk of heart-related side effects compared to other anesthetics, and Dexmedetomidine is commonly used to enhance the effects of local anesthetics. However, specific safety data for the combination of Dexmedetomidine and Ropivacaine in humans is not detailed in the available studies.12456

How is the treatment of dexmedetomidine and ropivacaine for shoulder pain different from other treatments?

This treatment is unique because it combines dexmedetomidine, which enhances pain relief, with ropivacaine, a local anesthetic, in a continuous interscalene brachial plexus block. This combination aims to provide longer-lasting pain relief after shoulder surgery compared to using ropivacaine alone.12789

What is the purpose of this trial?

Arthroscopic shoulder surgery is increasingly performed in an outpatient setting and post-operative pain management is often a real challenge as those surgeries are well recognized for their high level of pain which often affects physical rehabilitation. The interscalene block is a largely used anesthetic technique to perform these surgeries whilst avoiding general anesthesia (GA) and to provide postoperative analgesia. However, the painful period often exceeds the duration of a single shot block, thus affecting patient recovery. Some specialized centers use a continuous catheter and elastomeric pump in order to prolong the duration of analgesia. However, several logistical, professional and financial constraints limit the use of these catheters and pumps in a great number of outpatient centers. On the other hand, perineural dexmedetomidine is increasingly used as an adjuvant to improve block onset, analgesia duration and patient satisfaction.The use of adjuvants such as perineural dexmedetomidine added to a single shot interscalene block appears to be an interesting option to prolong postoperative analgesia without the limitations imposed by a continuous catheter and elastomeric pumps in arthroscopic shoulder surgeries.

Treatment Details

Interventions

  • Continuous Interscalene Brachial Plexus Block
  • Dexmedetomidine
  • Ropivacaine
  • Single Shot Interscalene Brachial Plexus Block Group with Dexmedetomidine Added to Ropivacaine Group
Trial Overview The trial is testing two methods to manage pain after shoulder surgery: one group receives a single shot of ropivacaine mixed with dexmedetomidine (a sedative), while another gets continuous pain relief through a catheter. The goal is to see if adding dexmedetomidine can extend pain relief without needing complex equipment.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: single shot interscalene brachial plexus with dexmedetomidine added to ropivacaineExperimental Treatment1 Intervention
A total of 150 mg of ropivacaine 0.5% will be prepared, 125 mg (25mL) will be mixed with a dose of 2 mcg/kg IBW of dexmedetomidine (100 mcg/mL dexmedetomidine hydrochloride; Precedex, Hospira Inc, Lake Forest, IL). The total of 25 mL (125 mg or ropivacaine 0.5%) with dexmedetomidine will be injected perineurally at the level of the roots and a 5 mL (25 mg) will be injected between the sternocleidomastoid muscle and anterior scalene for the superficial cervical plexus block.
Group II: continuous interscalene brachial plexus block with ropivacaineActive Control1 Intervention
A total of 100 mg (20 mL) of ropivacaine 0,5% will be injected perineurally at the level of the roots using the Tuohy needle. The 19 G arrow catheter will then be introduced through the Tuohy needle and we will leave 4 cm of the catheter perineurally. An additional 25 mg (5 mL) of ropivacaine 0,5% will be injected using the catheter to make sure the catheter is in a correct position. An additional 5 mL (25 mg) of ropivacaine 0.5 % will be injected between the sternocleidomastoid muscle and anterior scalene for the superficial cervical plexus block using an ultrasound in-plane approach with a 22 G 80-mm ultrasound needle (Pajunk SonoTAP II, Germany) or with a standard 25G 1 1/2 inches needle. After the surgery, an infusion of ropivacaine 0,2% at a standard rate of 5 mL/h will be started using an elastomeric pump of 300 mL (Baxter Corporation, Mississauga, Ontario).

Findings from Research

In a study of 62 patients undergoing shoulder surgery, both 8 ml/h and 6 ml/h infusion rates of 0.2% ropivacaine for continuous interscalene brachial plexus block provided similar pain relief and patient satisfaction, indicating effective analgesia at both rates.
Lowering the infusion rate to 6 ml/h is recommended to reduce the risk of local anesthetic toxicity while maintaining effective pain management after shoulder surgery.

In a study of 66 patients undergoing arthroscopic shoulder surgery, co-administering intravenous dexamethasone and dexmedetomidine significantly prolonged the time to first rescue analgesic request to 66.3 hours, compared to 17.4 hours for dexamethasone alone and 10.9 hours for the control group.
Both dexamethasone and the combination treatment resulted in lower pain scores, reduced opioid consumption, less sleep disruption, and higher patient satisfaction, with no significant increase in blood glucose levels, indicating a safe profile for these interventions.

In a study of 126 patients receiving continuous infusions of 0.25% bupivacaine after upper extremity surgery, over 70% reported postoperative pain scores of 4 or less, indicating effective pain management.
While the method was generally effective and easy to implement, 14.3% of patients experienced complications, primarily catheter dislodgement and pain at the insertion site, highlighting the need for careful monitoring.
