title: [Efficiency of secondary posterior trunk single stimulation, low volume infraclavicular plexus block for upper limb surgery].
abstract: OBJECTIVE
  To assess the efficiency of a posterior secondary trunk single stimulation, low volume (30 ml 1.5% mepivacaine) infraclavicular brachial plexus block (ICB) technique.
  
  
  METHODS
  Prospective study.
  
  
  METHODS
  One hundred consecutive patients scheduled for hand, forearm or elbow surgery were included. ICB was placed using a single stimulation technique. 30 ml 1.5% mepivacaine was injected when an evoked distal radial motor type response was elicited for 0.3-0.6 mA intensity current. Based upon both sensory and motor distribution ICB, characteristics and performance were assessed.
  
  
  RESULTS
  No patient required general anesthesia conversion. Success rate was 92%. 8 patients required a total amount of 10 complementary distal troncular blocks. No specific complication of ICB technique was accoutered. All patients completed full neurological recovery from ICB 24 hours after surgery.
  
  
  CONCLUSIONS
  30 ml mepivacaine 1.5% ICB is suitable for upper limb surgery.
