Can chronic poststernotomy pain after cardiac valve replacement be reduced using thoracic epidural analgesia?
BACKGROUND
The aim of our study was to evaluate the use of thoracic epidural analgesia (TEA) in acute pain management after cardiac valve replacement and determine if the incidence of chronic pain related to the sternotomy was reduced by the use of TEA. This patient group was chosen to exclude pain related to the use of the internal mammary artery and angina pectoris.


METHODS
Patients scheduled for elective cardiac valve replacement were offered TEA. A match-control group was selected. Epidural catheter placement, complications and postoperative neurological state were noted for both groups. Eighteen months postoperatively, a questionnaire was sent out concerning pain management, wound discomfort and pain.


RESULTS
Forty-nine patients were included. The TEA group consisted of 35 patients. At 18 months' follow up, 37% from the TEA group and 21% from the control group had pain or discomfort related to the sternum (NS). Two in the TEA group had severe pain.


CONCLUSIONS
We found in our small material that TEA provided excellent analgesia in the peri- and postoperative period, but we did not find a protective effect of TEA on chronic poststernotomy pain, neither weak pain nor severe pain.
