Keywords
Epidural block, Pancreatic cancer
Brief summary
The purpose of this randomized controlled clinical trial is to investigate the effects of epidural block on overall survival，disease-free survival and recovery in patients with pancreatic cancer undergoing distal pancreatectomy. This study will also evaluate the effects of this technique on neuroendocrine, stress and inflammatory response in these patients.
Interventions
OTHERGEA
Thoracic epidural catheterization will be performed and epidural anesthesia will be maintained with 0.25% ropivacaine during surgery. General anesthesia will be maintained with inhalation (sevoflurane) and muscle relaxants will be administered when considered necessary.
OTHERPCEA
Patient-controlled epidural analgesia (0.15% ropivacaine and 0.5ug/ml sufentanil infusion) will be provided after surgery.
OTHERGA
General anesthesia will be maintained with inhalation (sevoflurane) and sufentanil infusion, and muscle relaxants will be administered when considered necessary.
OTHERPCIA
Patient-controlled intravenous analgesia (1ug/ml sufentanil) will be provided after surgery.
