title: [Clinical anesthetic effects of epidural ropivacaine with tramadol].
abstract: OBJECTIVE
  To observe the anesthesic effects of epidural ropivacaine with tramadol during lower limbs surgery.
  
  
  METHODS
  Thirty patients (ASA I - II) scheduled for the lower limbs surgery were randomly divided into 2 groups with 15 patients in each group: group ropivacaine (R) and group ropivacaine with tramadol (T). The puncture was performed at the interspace of L2-3. Each patient was given 2% lidocaine 3 ml with 0.75% ropivacaine 10 ml which included NS 1 ml in Group R or tramadol 50 mg in Group T. The potency of analgesia, the time of sensation block to T12 and T10, the time to the highest plane of analgesia, the lasting time of analgesia, the degree of sedation, the degree of motor block, and the side effects were recorded and analyzed during anesthesia after the first dose.
  
  
  RESULTS
  The time of sensation block which reached T12 and T10 and the time to the highest plane of analgesia decreased significantly in Group T than that in Group R (P < 0.05). The lasting time of analgesia in Group T was longer than that in Group R (P < 0.05). There was no significant difference in the potency of analgesia, the degree of sedation and motor block, and the side effects (P > 0.05).
  
  
  CONCLUSIONS
  The epidural ropivacaine with tramadol enhanced the anesthetic effects of ropivacaine.
