Study Overview
Brief Summary
The rebound pain after nerve block could interfere with the patient's recovery and rehabilitation. It is not known how intravenous dexamethasone affects rebound pain. This study aims to evaluate the effect of intravenous dexamethasone on rebound pain after interscalene block for shoulder surgery.
Detailed Description
Shoulder rotator cuff repair and acromioplasty are associated with severe postoperative pain. The interscalene block (ISB) is commonly used for this type of surgery, providing analgesia by anesthetizing the nerves that supply the shoulder. Although the nerve block provides extremely effective analgesia for the first 6-8 hours, patients experience severe pain once its effect has been wearing off. Rebound pain is a severe pain that occurs when the effect of a nerve block disappears in a patient during the postoperative period. The purpose of this study is to investigate whether the use of intravenous dexamethasone reduces rebound pain in patients recruiting for shoulder surgery with interscalene brachial plexus blockade.
This study will be conducted as a single-center, prospective, randomized, double-blinded trial in a university hospital. Patients scheduled for elective shoulder surgery will be screened for enrollment in the study. All subjects will undergo ultrasound-guided interscalene nerve block before induction of general anesthesia. They will be randomly assigned into the two groups which use intravenous dexamethasone or not. An anesthesiologist who will perform blocks will not involve in the data collection. Other health care workers who will involve in the evaluation of postoperative pain scores, nausea and vomiting, opioid consumption, quality of Sleep, and Quality of Recovery score will be blinded to the group assignment.

Outcomes
Primary Outcomes
Incidence of rebound pain
Time Frame: One week after surgery
Rebound pain is described as severe pain (NRS ≥ 7)
The difference of pain score before and after interscalene block resolution
Time Frame: First 12 hours after interscalene block effect disappears
The difference in the pain score between when the block is working and when it has resolved. Pain scores (0 = no pain; 10 = worst pain imaginable) using a Numerical Rating Scale (NRS) ranging from 0 to 10.
Secondary Outcomes
- Analgesic consumption(Postoperative 48 hours)
- Interscalene block resolution time(Postoperative 24 hours)
- Number of Participants with Surgical infection(Postoperative 14 days)
- Quality of Recovery 15 Score(Postoperative day 1 and day 7)
- Glucose measurement(Postoperative 24th hour)
- Sleep Quality measured with Likert Scale(One week after surgery)
- Numeric Rating Scale pain score ( NRS)(Postoperative 48 hours)
