Abstract :

 

Supraclavicular achial plexus blocks are more predictable regional anesthetic technique than other methods for upper limb surgeries with minimal adverse effects. The nerve blocks were performed initially based on anatomical landmark technique by elicitation of paresthesia with needle. Paresthesia is a subjective response and due to direct contact of the needle with nerve, neuronal damage can occur frequently. In order to minimize these complications with the equal success rate an objective response equipment, Nerve stimulator was introduced in clinical practice. It is also a anatomical landmark oriented technique and may lead to residual neuronal damage.  The introduction of Ultrasonogram has generated a yearning of identifying the better technique with more success and least complication rate.. Therefore we conducted a study to compare the usefulness of ultrasound and nerve stimulator for supra clavicular achial plexus block in upper limb surgeries.

 

AIMS & OBJECTIVES:

 

     To compare the effects of supraclavicular achial plexus block using nerve stimulator and USG technique in terms of time taken for the procedure (Block execution time) , onset of sensory blockade , onset of motor blockade, success rate incidence of complications , total duration of analgesia  

SAMPLE SIZE AND RANDOMIZATION:

          The sample size was scheduled to be 60 based on the pilot study. They were randomly selected to 30(n=30) in each group and named as Group US (ultrasound) and Group NS (Nerve stimulator).NS Group: Supraclavicular achial plexus block performed withthe guidance of Nerve Stimulator US Group: Supraclavicular achial plexus block performed throughUltrasound guidance.

CONCLUSION:

 

We concluded that Ultrasound guided supraclavicular achial plexus block for patients undergoing upper limb surgeries provided rapid onset of sensory and motor blockade than NS group and also extends the duration of analgesia with good hemodynamic stability. Block execution time by US group was longer than NS group. Success rate achieved by both methods are similar and occurrence of complications such as vascular puncture and paresthesia was seen more in NS group.
