Objective: An acute severe stress response associated with major surgery can adversely affect the inflammatory and hormonal responses. We hypothesised that total intravenous anaesthesia (TIVA) combined with thoracic epidural anaesthesia and analgesia (TEA) attenuates the stress response and postoperative pain in patients undergoing radical oesophagectomy.
Methods: Forty patients scheduled for elective radical oesophagectomy were randomly assigned to one of two groups: TIVA or TIVA+TEA. The plasma levels of stress hormones and cytokines, consumption of fentanyl, postoperative visual analogue scale (VAS) scores within 48 hours, and extubation time were assessed.
Results: The plasma levels of interleukin-6, norepinephrine, cortisol, and adrenocorticotropic hormone at 3 hours after the beginning of surgery were significantly higher in the TIVA group than TIVA+TEA group. The plasma level of interleukin-10 at 3 hours after the beginning of surgery was significantly lower in the TIVA group than TIVA+TEA group. The consumption of fentanyl was significantly greater, VAS scores were significantly higher, and extubation time was significantly longer in the TIVA group than TIVA+TEA group.
Conclusions: The findings suggest that combination of TIVA and TEA may attenuate the intraoperative stress response and postoperative pain in patients undergoing radical oesophagectomy.
