Dexmedetomidine and Ketamine as an Adjuvant in External Oblique Intercostal Plane Block for Post Thoracotomy Pain
Comparison Between Role of Dexmedetomidine and Ketamine as an Adjuvant in External Oblique Intercostal Plane Block for Post Thoracotomy Pain: A Randomized Trial
Study Overview
Status
Intervention / Treatment
Detailed Description
Postsurgical pain in patients who have undergone open thoracotomy for lung cancer or other lung surgeries is known to be very severe.
As a result, this pain alters spontaneous breathing, delays postoperative recovery, and persists as chronic post-thoracotomy pain syndrome . Post-thoracotomy pain syndrome is relatively common and is seen in approximately 50% of patients after thoracotomy. It is a chronic condition, and about 30% of patients might still experience pain 4 to 5 years after surgery.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time to the 1st rescue analgesia
Time Frame: 48 hours postoperative.
|
A standardized analgesic regimen will be prescribed in the post-operative period.
All patients will receive paracetamol 1 gm every 6 h as routine analgesia.
Rescue analgesia of morphine will be given as 3 mg bolus if the numeric rating scale (NRS) > 3 to be repeated after 30 min if pain persists until the NRS < 4. NRS will be assessed at 0, 4, 8, 12, 18, 24, 36 and 48 h postoperatively.
|
48 hours postoperative.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Intraoperative fentanyl consumption
Time Frame: Intraoperative
|
Additional fentanyl bolus dosages of 1 µg/kg IV will be administered if heart rate or mean arterial blood pressure elevated more than 20% of the baseline (after exclusion of other causes than pain).
|
Intraoperative
|
Heart rate
Time Frame: Till the end of surgery.
|
Heart rate will be recorded preoperative, before performing of block, and every 15 min till the end of surgery.
|
Till the end of surgery.
|
Total morphine consumption in the 1st 24hr and 48 hr
Time Frame: 48 hours postoperatively.
|
Rescue analgesia of morphine will be given as 3 mg bolus if the numeric rating scale (NRS)> 3 to be repeated after 30 min if pain persists until the NRS < 4. NRS will be assessed at 0, 4, 8, 12, 18, 24, 36 and 48 h postoperatively. NRS (0 represents "no pain" while 10 represents "the worst pain imaginable") |
48 hours postoperatively.
|
Degree of pain
Time Frame: 48 hours postoperatively.
|
Degree of pain will be assessed by the numeric rating scale (NRS).
NRS (0 represents "no pain" while 10 represents "the worst pain imaginable").
It will be assessed at 0, 4, 8, 12, 18, 24, 36 and 48 h postoperatively.
|
48 hours postoperatively.
|
Mean arterial blood
Time Frame: Till the end of surgery.
|
Mean arterial blood will be recorded preoperative, before performing of block, and every 15 min till the end of surgery.
|
Till the end of surgery.
|
The incidence of adverse events
Time Frame: 48 hours postoperative
|
Adverse events such as pneumothorax, local anesthetic systemic toxicity (LAST), bradycardia, hypotension, nausea, vomiting, respiratory depression, or any other complication.
|
48 hours postoperative
