Summary

Different modalities ranging from patient controlled analgesia (PCA) to different regional blocks have been used to control postoperative pain after thoracic surgeries. Thoracic epidural analgesia and paravertebral blocks are effective modes of pain relief but have the risks of severe complications and side effects which include severe hypotension, nerve injury or spinal cord injury, vascular injury and pleural injury etc. Erector spinae plane block (ESPB) is relatively new regional technique which was described by Forero et al in 2016. Several studies have demonstrated an effective role of ESPB in controlling pain for thoraco-abdominal surgeries which include breast surgery, thoracic surgery and upper GI laparoscopy. Shim et al in their study showed that ESPB significantly reduced pain score in first 6 hours postoperatively in patients who underwent VATS. The aim of this study is to evaluate the effect of ESPB using catheter on postoperative 24 hours opioid consumption in video-assisted thoracoscopy (VATS)

Detailed description

Video-assisted thoracoscopic surgery (VATS) is more commonly used technique nowadays in thoracic surgery. This technique is associated with lesser postoperative pain, better postoperative pulmonary function, decreased mortality and shorter hospital stay. However, patients can have severe and prolonged postoperative pain following VATS. Homma et al reported that 18.8 % of patients have persistent pain following VATS. Acute postoperative pain is considered to be one of strong predictor of persistent pain postoperatively. Different modalities ranging from patient controlled analgesia (PCA) to different regional blocks have been used to control postoperative pain after thoracic surgeries. Thoracic epidural analgesia and paravertebral blocks are effective modes of pain relief but have the risks of severe complications and side effects which include severe hypotension, nerve injury or spinal cord injury, vascular injury and pleural injury etc. Erector spinae plane block (ESPB) is relatively new regional technique which was described by Forero et al in 2016. Several studies have demonstrated an effective role of ESPB in controlling pain for thoraco-abdominal surgeries which include breast surgery, thoracic surgery and upper GI laparoscopy. Shim et al in their study showed that ESPB significantly reduced pain score in first 6 hours postoperatively in patients who underwent VATS. The objective of this study is to investigate the role of ESPB using catheter in reducing opioid requirements in first 24 hours after VATS.

Interventions

Type	Name	Description
PROCEDURE	Erector spinae plane block catheter	All ESP blocks will be performed in lateral position after general anesthesia induction. ESPB will be performed under ultrasonographic guidance using a linear 6- to 10-MHz ultrasound probe. The linear ultrasound transducer will be placed in a longitudinal parasagittal orientation 3 cm lateral to the T6-10 spinous process. The erector spinae muscles will be identified superficial to the tip of the transverse process. A 21-gauge 10-cm needle will be inserted using an in-plane superior-to-inferior approach or an out of plane approach. The tip of the needle will be placed into the fascial plane on the deep (anterior) aspect of erector spinae muscle. The location of the needle tip will be confirmed by visible fluid spread lifting erector spinae muscle off the bony shadow of the transverse process on Ultrasonographic imaging. A total of 10-15 ml of 0.2% ropivacaine will be injected each side. A catheter will then be placed leaving 5 cm in place.
