Upper Extremity Injury Trauma Clinical Trial
Official title:
Role of Echogenic Versus Nonechogenic Needles in Ultrasound Guided Infraclavicular Brachial Plexus Block Success Rate: A Comparative Study
In this prospective, randomized, double blinded study, the needle tip and needle shaft visibility of echogenic and nonechogenic needle were compared in ultrasound guided infraclavicular brachial plexus block. Sixty patients scheduled for upper extremity surgery were included in the study. Patients were randomised into two groups, group E (Echogenic) and group NE (Nonechogenic) with 30 subjects in each group. Under ultrasound guidance infraclavicular brachial plexus block was performed. In Group E, Pajunk Sonoplex echogenic needle was used and in Group NE, Stimuplex Braun nonechogenic needle was used. The subjective assessment for needle tip/shaft visibility as scored by the performer and the objective assessment from the recorded block procedure video were noted.
The aim of the investigators study was to find out the better among the echogenic and
nonechogenic needle in needle tip/shaft visibility and the block success rate in ultrasound
guided infraclavicular brachial plexus block. Sixty patients were randomized into two
groups, Group E (echogenic group) and Group NE (nonechogenic group) with thirty patients in
each group. The ultrasound imaging of each nerve block was video recorded for later
analysis. Recording commenced from skin puncture and stopped at the time of final needle
removal (total block time). After each block the performer was asked to subjectively score
the percentage time he had visualized the needle tip and needle shaft on a 5 point scale (1
= 0%-20%, 2 = 20%-40%, 3 = 40%- 60%, 4 = 60%-80%, 5 = 80%-100%). The recorded video was
later analysed by an investigator. An objective measurement of percentage needle tip
visibility and needle shaft visibility was calculated for each nerve block using the
formula,
Time in view (needle tip) / total block time x 100
Time in view (needle shaft) / total block time x 100
The subjective assessment for needle tip/shaft visibility as scored by the performer and the
objective assessment from the recorded block procedure video were noted. Other block
parameters were also compared.
