Summary
Several reports have compared the duration of action of levobupivacaine and ropivacaine as
local anesthetic. The most widely used method for sensory function evaluation is though means
of a pinprick test. The investigators want to use the novel method of Quantitative Sensory
Testing to better evaluate the anesthetic activity. This method used hot and cold sensation
to assess small nerve fiber function. The investigators will assess the duration of action of
different drugs when used in an inter scalene nerve block in patients scheduled for shoulder
surgery.
