Brief Summary:
The Erector Spinae Plane (ESP) block is a new interfascial regional anesthesia technique recently described by Forero et al. Currently the literature shows the ESP block being used for analgesia after thoracic surgery, breast surgery, abdominal surgery (visceral abdominal analgesia in bariatric surgery, ventral hernia repair, cholecystectomy), thoracic vertebral surgery and for pain relief in rib fractures. Taking in consideration the excellent clinical experience, but the lack of strong and high-quality evidence, supporting the use of ESP block for pain management in patients undergoing VATS procedures, there is a specific interest to develop a prospective study. Comparing the effect of the current pain relief strategy at the MGH (intercostal nerve block by the surgeon at the end of the procedure ) versus ESP block after VATS, seems warranted to improve current clinical results.

Arm Intervention/treatment
Experimental: ESP block
patients will receive an ultrasound guided ESP block (technique as described by Forero et al) under strict sterile conditions in the operating room area. After identifying the T5 transverse process (TP) and after infiltration of lidocaine 2% subcutaneously. A 22g 100mm block needle will be advanced under vision, in a cephalad to caudad direction, until the tip contacts the T5 TP. 20 ml of 0.25% bupivacaine with 5 mcg/ml of epinephrine and 10 mg dexamethasone will be injected under the erector spinae muscle. A visible separation of the erector spinae muscle from the TP will be the sign of a successful block. A 20 ml syringe of Normal Saline will be given to the surgeon (unaware of the content) at the end of the surgery, for the intercostal nerve block as per standard present technique.
Procedure: ESP block

ESP with 20 ml of Bupivacaine 0.25%, Epinephrine 5mcg/ml and Dexamethasone 10mg.

Sham intercostal block with 20 ml Normal Saline


Procedure: Sham Intercostal block

Sham Comparator: ESP sham block
patients will receive an ultrasound guided sham ESP block under strict sterile conditions in the operating room area as described above. 20 ml of Normal Saline will be injected under the erector spinae muscle. A 20 ml syringe of 0.25% bupivacaine with 5 mcg/ml of epinephrine and 10 mg dexamethasone will be given to the surgeon (blinded to the content) at the end of the surgery for the intercostal nerve block.
Procedure: Intercostal block

Primary Outcome Measures :
  1. Efficacy of ESP block versus Intercostal nerve block in decreasing opioid consumption [ Time Frame: Measured at 24 hours postopertively ]
    measured by total intravenous morphine consumption at 24 hours postopertively. A 25% reduction in morphine consumption would be considered statistically significant.


Secondary Outcome Measures :
  1. Efficacy of ESP block versus Intercostal nerve block in decreasing pain intensity at rest: Numerical Rating Scale (NRS) [ Time Frame: measured at post operative 2, 4, 12, 24 and 48 hours ]
    Pain levels will be assessed using the 10 points Numerical Rating Scale (NRS) where zero= no pain and 10= pain as bad as it can be. The NRS is a validated tool to measure pain and discomfort. It is sensitive to pharmacological and non-pharmacological interventions, that have an impact over the experience of pain, as well as it's high correlation with pain levels

  2. Efficacy of ESP block versus Intercostal nerve block in decreasing pain intensity upon mobilization: Numerical Rating Scale (NRS) [ Time Frame: measured at post operative 2, 4,12, 24 and 48 hours ]
    Pain levels will be assessed using the 10 points Numerical Rating Scale (NRS) where zero= no pain and 10= pain as bad as it can be. The NRS is a validated tool to measure pain and discomfort. It is sensitive to pharmacological and non-pharmacological interventions, that have an impact over the experience of pain, as well as it's high correlation with pain levels

  3. Change in pulmonary function [ Time Frame: pre-operatively and 2, 4, 12, 24 and 48 hours after the procedure ]
    This will be assessed using the incentive spirometer, which allows for crude measurement of inspired volumes

  4. Total opioid consumption [ Time Frame: 48 hours post operatively ]
    In morphine equivalencies

  5. Ipsilateral shoulder pain scores [ Time Frame: 2, 4, 12, 24 and 48 hours after the procedure ]
    Pain levels will be assessed using the 10 points Numerical Rating Scale (NRS) where zero= no pain and 10= pain as bad as it can be. The NRS is a validated tool to measure pain and discomfort. It is sensitive to pharmacological and non-pharmacological interventions, that have an impact over the experience of pain, as well as it's high correlation with pain levels

  6. Incidence of adverse events [ Time Frame: Over the first 48 hours ]
    postoperative nausea and vomiting (PONV), hypotension, urinary retention (requiring placement of an indwelling or a temporary catheter), pruritis and oxygen requirements

  7. Length of stay in the post anesthesia care unit (PACU) [ Time Frame: up to 24 hours ]
    total time spent in the PACU until reaching PACU discharge criteria

  8. Length of stay in the hospital [ Time Frame: up to 10 days ]
    total time spent in the hospital until reaching hospital discharge criteria

  9. Time to first mobilization to the chair [ Time Frame: Measured from the arrival time to PACU ]
  10. Time to first ambulation (walking) out of bed [ Time Frame: Measured from the arrival time to PACU ]
  11. Block performance time [ Time Frame: Up to 40 minutes ]
    The time it takes to perform the ESP block

  12. Block related adverse events [ Time Frame: First 4 hours postopertively ]
    Incidence of block related adverse events such as bleeding, pneumothorax and local anesthetic systemic toxicity
