Plain English Summary
Background and study aims
Thoracic surgery includes operations on all parts of the chest including the chest wall, the contents of the chest and the lungs, except for heart surgery. A thoracotomy is a surgical incision (cut) into the chest wall to open the chest cavity. Post-thoracotomy pain is felt in the back and chest region after a thoracotomy. The aim of this study is to find out whether dexmedetomidine plus local anesthetic Levobupivacaine could extend pain relief time compared with Levobupivacaine alone at the end of thoracic surgery.
Who can participate?
Patients aged 20-60 undergoing elective thoracic surgery
What does the study involve?
Participants are randomly allocated to one of two groups. One group receive levobupivacaine and the other group receive levobupivacaine plus dexmedetomidine. Participants’ pain, opioid (pain relief) consumption and adverse effects are monitored.
What are the possible benefits and risks of participating?
The results of this study will help to confirm the best method of pain relief and the patient may benefit from pain relief. No risks are expected.
Where is the study run from?
National Cancer Institute, Cairo University (Egypt)
When is the study starting and how long is it expected to run for?
March to September 2017

Condition
Post-thoracotomy pain
Intervention
Patients will be randomized by double-blind simple randomization to two groups.
1. 25 patients will receive a bolus of 30 ml of 0.25% levobupivacaine followed by an infusion of 5 ml/hour of 0.125% levobupivacaine.
2. 25 patients will receive a bolus of 30 ml of 0.25% levobupivacaine plus 1 ug/kg dexmedetomidine followed by an infusion of 0.125% levobupivacaine plus 0.2 ug/kg/hour dexmedetomidine at a rate of 5 ml/hour.
All patients receive the study medications through ultrasound-guided serratus anterior catheter.
Patients will be monitored for:
1. Arterial blood pressure, heart rate and oxygen saturation every 10 min for the initial one hour of the blockade; subsequently every half an hour for the next 2 hours and then 2 hourly for the next 12 hours. As soon as the patient is alert enough VAS pain score will be recorded every 2 hours
2. Total morphine consumption during first 24 hours postoperatively
3. Sign of morphine side effects such as nausea, vomiting, dizziness, an unusual pleasant feeling, sweating, headache, anxiety and constipation

Primary outcome measures
Postoperative pain at rest and coughing, measured by VAS pain score (10 mm vertical scale from 0-10 where zero means no pain and 10 is the worst pain) every 2h in the first 24h postoperative
Secondary outcome measures
1. Postoperative opioid consumption, recorded by staff during first 24 hours postoperative
2. Adverse effects including nausea, vomiting, hypotension and cardiac arrhythmias, recorded by staff in the first 24h postoperative
