Summary

Peripheral nerve blocks with use of USG allowed visualisation of the structures and nerves and made the block administrations safe, quick and comfortable. However there are few publications concerning the minimum local anesthetic volume capable of providing blocks. In this study the investigastors aimed to find Minimum Effective Volume Of Local Anesthetic For Ultrasound-Guided İnfraclavicular Approach for Brachial Plexus Blockade in upper limb operations.

Conditions

  • Underdosing of Local Anesthetics
  • Anesthetics, Local
  • Peripheral Nervous System Agents
  • Physiological Effects of Drugs

Interventions

OTHER

Procedure/Surgery: bupivakain % 0,5

In this study, 5 patients were included in each volume group and at least 3 applications out of 5 had to be successful to consider the volume to be sufficient. After a successful group, the volume was reduced by 2 ml's and the same procedure was followed until a final group with unsuccessful anesthesia was found (≤2 successful blockades). The study was ended at this point and MEV was determined as the volume used in the last successful group. The researcher which determined the success of blockade was blinded to the study protocol. BMI, ASA Score, Successful blockade onset time Regression time of sensorial blockade Regression time of motor blockade Time of first additional analgesic requirement
