Pain, Postoperative
Conditions
Brief summary
Up to our knowledge there is no study focused upon the incidence of post VATS chronic pain when dexmedetomidine is used.
Detailed description
Most Video-Assisted Throcoscopy Surgery (VATS) procedures are considered low-risk interventions requiring short hospital stays or even outpatient settings. Because of these factors, VATS did not raise as much interest as thoracotomy in its postoperative pain management. However, it is a fact that pain following VATS can be severe and long-lasting .According to Richardson and colleagues, 38% of VATS procedures present persistent pain two months after surgery as a result of acute nerve damage during the surgical procedure.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| acute postoperative pain | 24 hours | assessment of pain by visual analog scale (VAS) by cm with minimal =0 and maximal =10, worst pain mean scale of 10 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| chronic post thoracic surgery pain | 3 months | Chronic neuropathic pain was assessed using the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Pain Scale with non-neuropathic pain if the scale \<12, and neuropathic pain is likely to be the contributing cause of pain if the scale \>12 |
