Primary Outcome Measures:
  • Plasma concentration of the local anesthetics in study [ Time Frame: during 60h after surgery ]
    Assessment of the equivalence of the systemic exposition of levobupivacaine and ropivacaine during 48h continuous epidural infusion with in a range of 15%.Blood samples (8) will be taken for farmacological assessment of local anesthetic plasma concentrations at time (hours) 0,+3h,+6h,+12h,+24h,+48h,+54h,+60h


Secondary Outcome Measures:
  • Assessment of the pharmacological profile of the local anesthetics in study [ Time Frame: during 60h after surgery ]
    Assessment of the therapeutic index (plasma concentration of the local anesthetics in study compared to those described in literature to be related to toxic effects).

  • Difference between the to groups (at least 25%) in terms of pain control (1 episode of VAS>4) [ Time Frame: Pain control (VAS, VASm, rescue dose) during the 72 h postsurgery ]
  • Difference at least 20% in presentation of collateral effects between the two groups [ Time Frame: Continuous assessment during the 72 h post-surgery ]

Arms Assigned Interventions
levobupivacaine Drug: local anesthetic

postoperative 48h epidural continuous infusion,

  1. ropivacaine 0,2% (250ml)+ sufentanil 0,75mcg/ml
  2. levobupivacaine 0,125% (250ml)+ sufentanil 0,75mcg/ml
Other Names:
  • Chriocaina
  • Naropina
ropivacaine Drug: local anesthetic

postoperative 48h epidural continuous infusion,

  1. ropivacaine 0,2% (250ml)+ sufentanil 0,75mcg/ml
  2. levobupivacaine 0,125% (250ml)+ sufentanil 0,75mcg/ml
Other Names:
  • Chriocaina
  • Naropina

Detailed Description:

In literature the systemic toxicity of bupivacaine is widely demonstrated, like the minor toxicity of levobupivacaine and ropivacaine at the same anesthetic potency. The are actually no studies in humans confronting levobupivacaine and ropivacaine under the aspect of efficacy and toxicity.The aim of the study is the assessment of the systemic absorption of local anesthetics during continuous epidural infusion for postoperative pain control.

Primary outcome:

Assessment of the plasmatic equimolar concentrations of levobupivacaine and ropivacaine during continuous epidural infusion

Secondary outcome:

Assessment of the safety level of the local anesthetic (major difference between haematic concentration of the local anesthetic and neuro-cardiotoxic dose).

Difference of the analgesic efficacy between levobupivacaine and ropivacaine. Differences in collateral effects due to the local anesthetic: hypotension and sensitive block.
