Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Thoracic epidural analgesia and thoracic paravertebral block are strongly recommended techniques for managing post thoracotomy pain to reduce opioid use and the related adverse effects as hypoventilation, depression of cough reflex, nausea and vomiting. However, they can be technically challenging to perform and are associated with up to 15% failure rate in Thoracic epidural analgesia and potential risk of pneumothorax in thoracic paravertebral block.
Erector spinae plane block is a relatively novel ultrasound-guided regional technique. Its application in patients with chronic thoracic neuropathic pain and acute surgical pain has been described by Forero et al.
Retrolaminar block is an easy and safe analgesic technique. It has been reported to be satisfactory for post-operative analgesia after breast surgery.
To our knowledge there is no clinical studies, comparing the effectiveness of both blocks on postthoracotomy pain, has been reported.

Patients received general anesthesia alone.
Control
General anesthesia
Ultrasound-guided Erector Spinae Plane Block
A 22-gauge needle is inserted at a puncture site lateral to the target spinous process using ultrasound imaging and advanced until contact is made with the transverse process. The local anesthetic agent will be injected between the transverse process and the erector spinae muscle using 20 ml (19ml bupivacaine 0.25% plus 1ml dexamethasone 4mg).
Ultrasound-guided Erector Spinae Plane Block
ultrasound-guided ipsilateral Erector Spinae Plane Block (20 ml (19ml bupivacaine 0.25% plus 1ml dexamethasone 4mg)).
Retrolaminar Block
A 22-gauge needle is inserted at a puncture site lateral to the target spinous process using ultrasound imaging and advanced caudally or cranially until it contacts the lamina. The local anesthetic agent will be injected on the lamina using 20 ml (19ml bupivacaine 0.25% plus 1ml dexamethasone 4mg).
Retrolaminar Block
ultrasound-guided ipsilateral Retrolaminar Block (20 ml (19ml bupivacaine 0.25% plus 1ml dexamethasone 4mg)).
