| Summary: | Introduction: Brachial plexus blockade at the supraclavicular
level delivers an excellent regional anaesthetic technique
with unmatched effectiveness for upper limb surgeries.
Levobupivacaine, a safer alternative to the commonly used
bupivacaine for regional anaesthesia and addition of a2-
agonists like dexmedetomidine further improves the quality of
regional anaesthesia.
Aim: To evaluate the efficacy of levobupivacaine in combination
with dexmedetomidine for supraclavicular brachial plexus block.
Materials and Methods: This randomised controlled study
enrolled 50 American Society of Anaesthesiologist (ASA) grade I
and II patients aged between 18-60 years posted for elective
upper limb surgeries. Randomisation was done and the patients
were divided into two groups with 25 each, to receive either 39 mL
of 0.5% levobupivacaine and 100 μgs (1 mL) of dexmedetomidine
in group LD (Levobupivacaine with Dexmedetomidine) and
39 mL of 0.5% levobupivacaine and 1 mL of normal saline in
group LS (Levobupivacaine with Saline). The onset and duration
of sensory and motor blockade along with duration of analgesia
were observed. All Quantitative data were compared and
analysed using student’s unpaired t test while qualitative data
were analysed using Chi-square test. A p-value of less than 0.05
was considered to be statistically significant.
Results: The onset of sensory and motor blockade in group LD
was significantly faster when compared to group LS (p<0.001).
group LD had a longer mean duration of sensory and motor
blockade along with duration of analgesia when compared to
group LS (p<0.001). There was a better hemodynamic stability in
group LD when compared to group LS.
Conclusion: Dexmedetomidine added to levobupivacaine
provides significantly shorter onset times, greatly prolongs the
duration of sensory and motor blockade along with duration of
analgesia without any systemic side effects. |
