Introduction: Regional anesthesia in the form of brachial plexus block is a well known technique for orthopaedic upper limb surgery. More recently it has been shown that during infraclavicular blockade injection of local anesthetic after posterior cord stimulation is associated with more success rate ( upto 96%) than medial or lateral cord stimulation.
Objective: Therefore we planned this study to determine the efficacy of vertical approach of infraclavicular block using electrostimulation guided cord stimulation in upper limb surgeries.
Materials and Methods: This study was conducted on 60 ASA physical status grade I or II of both sexes between 20 and 60 years of age scheduled for forearm and hand surgery.Unwilling patients, patients with history of allergy to local anaesthetics, infection at local site of block, sensory neuropathy or motor deficit in the arm on which surgery is to be performed were excluded from the study.
Results: In the present study we observed mean age was 35.50±12.63 yr. Out of 60 cases 42 (70%) are male and 18 (30%) are female. Incidence of successful block in axillary nerve was (76.7%), MCN (86.7%), radial (96%), median (86.7%), ulnar (93.3%), MCNA (86.7%), MCNF (83.3%) and ICBN (83.3%). ‘Complete sensory block’ was achieved in 48 (80%) cases. Successful block was observed in 58 (96.6%) cases
Conclusion: We conclude that vertical infraclavicular block provided higher incidence of complete sensory block (blockade of all 8 nerve territories).
