Efficacy of Ultrasound-guided Erector Spinae Plane Block Versus Retrolaminar Block for Postoperative Analgesia in Patients Undergoing Thoracotomy
Comparing efficacy of Ultrasound-guided Erector Spinae Plane Block versus Retrolaminar Block for Postoperative Analgesia in Patients Undergoing Thoracotomy
Thoracotomy is one of the most painful surgical procedures. The reported incidence of persistent pain after thoracic surgery (post thoracotomy pain syndrome) has been reported in 20%-70% of patients. Inadequately treated post thoracotomy pain can have several negative consequences. Therefore, pain relief is essential to facilitate coughing and deep breathing and to promote early mobilization.
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.
