About this trial
This study aims to compare paravertebral block and thoracic epidural in awake thoracotomy.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age from 18 to 60 years.
Both genders.
American Society of Anesthesiologists (ASA) physical status classification II or III.
Scheduled for thoracotomy.
Disqualifiers
Poor cardiac function (ejection fraction less than 50%).
Patients with bad pulmonary function testing (PFTs). Absolute contraindication to thoracic epidural anesthesia includes patient refusal, allergy to local anesthetics, coagulopathy, active neurologic disorders, skin infection at the insertion site, uncooperative patients, uncontrolled cough, and unfavorable anatomy for thoracic epidural.
Thoracic spine disorders require chest wall resection or emergency thoracic surgery.
Had a previous thoracotomy (scarring due to prior surgery can limit the effectiveness of paravertebral block, and these patients may have existing chronic pain).

Treatment groups
Trial outcomes
Primary outcomes
Intraoperative fentanyl consumption
Additional bolus doses of fentanyl 0.5µg/kg will be given if the mean arterial blood pressure or heart rate rises above 20% of baseline levels.
Secondary outcomes
Time to the 1st rescue analgesia
Time to first request of rescue analgesia will be assessed from the end of surgery till first dose of morphine administrated.
Mean arterial pressure
Mean arterial pressure will be recorded at baseline, and every 15min till the end of surgery
Heart rate
Heart rate will be recorded at baseline, and every 15min till the end of surgery
Total morphine consumption
If numeric rating scale (NRS)\>3 at rest will be observed, rescue analgesia via IV morphine 3 mg boluses will be administered.
