Conditions
Rebound Pain
Registration Number
NCT05141461
Lead Sponsor
Karaman Training and Research Hospital
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.

Primary Outcome Measures
NameTimeMethod
Incidence of rebound painOne week after surgery

Rebound pain is described as severe pain (NRS ≥ 7)

The difference of pain score before and after interscalene block resolutionFirst 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 Outcome Measures
NameTimeMethod
Numeric Rating Scale pain score ( NRS)Postoperative 48 hours

Pain scores (0 = no pain; 10 = worst pain imaginable) using a Numerical Rating Scale (NRS) ranging from 0 to 10. It will be recorded at the 2nd, 4th, 6th, 8th, 12th, 16th, 18th, and 24th hours in the postoperative period

Analgesic consumptionPostoperative 48 hours

Rescue analgesic consumption in the first 48 hours postoperatively will be recorded.

Interscalene block resolution timePostoperative 24 hours

The time of the first analgesic request. If the patient will not need analgesic, the block will be accepted as resolved when numbness or heaviness will not be felt by the patient.

Number of Participants with Surgical infectionPostoperative 14 days

Number of Participants diagnosed with surgical infection

Quality of Recovery 15 ScorePostoperative day 1 and day 7

Quality of Recovery (QoR)-15 survey.Minimum value: 0, Maximum value: 150, higher scores mean better.

Glucose measurementPostoperative 24th hour

Glucose measurement

Sleep Quality measured with Likert ScaleOne week after surgery

Patients' perceived sleep quality will be assessed with a Likert scale. Likert scale is scored from Likert scale where 1 = very dissatisfied, 2 = dissatisfied, 3 = neutral, 4 = satisfied and 5 = very satisfied.
