The local anesthetic mixtures are performed for peripheral nerve blocks to accelerate the onset time of sensorial and motor blocks. Also adjuvant agents can be added to local anesthetics to improve the quality and duration of plexus blocks. In this study, we compared the effect of tramadol and fentanyl as adjuvant agents to local anesthetic mixtures in axillary plexus block for orthopedic upper extremity surgery. After approval of hospital ethics committee and written patient consent, sixty patients were enrolled to the study in three groups; The Control Group (Group C, 40 mL of 0.25% levobupivacaine + 40 mg lidocaine n:20), the Fentanyl Group(Group F, 40 mL of 0.25% levobupivacaine + 40 mg lidocaine + 50 mcg fentanyl n:20), the Tramadol Group (Group T, 40 mL of 0.25% levobupivacaine + 40 mg lidocaine + 100 mg tramadol n:20) for axillary plexus block. Groups were compared for partial and complete motor and sensorial block, onset time, partial and complete motor and sensorial block recover time, and postoperative first analgesic requirement time (VAS >4). In Group T partial sensorial block onset time was shorter than Group C and complete sensorial block onset time was shorter than Group C and Group F. In Group T complete sensorial block recover time was longer than Group C and Group F. The postoperative first analgesic requirement time was significantly longer in Group T and F when compared with Group C and significantly longer in Group T when compared with Group F. We conclude that the addition of tramadol or fentanyl to local anesthetic mixtures as an adjuvant agent for axillary block provide better postoperative analgesia for orthopedic upper extremity surgery. Furthermore tramadol more improves the block quality than fentanyl.
