Analgesic Efficacy of Dexmedetomidine Added to Fentanyl in PCEA

intra and post operative TEA infusion of (bupivacaine +fentanyl 2 mic/ ml+ dexmedetomidine 0.5 mic/ ml) Under strict aseptic precautions thoracic epidural was performed using a 16 gauge,Tuhy epidural needle by a paramedian approach. T8-T9 inter space was chosen for the injection. Skin at insertion site was anesthetized by 3 ml of lidocaine 1%, the epidural space was identified by the loss of resistance technique, the catheter was introduced approximately 2-4 cm into the epidural space, epidural test dose consisted of 3 ml of lidocaine 2 % with 1: 200,000 adrenaline.
