Introduction: Regional nerve block is one of important
and effective ways for analgesia and anesthesia
during surgery and post-operative pain control which
while providing optimum conditions for surgery and
faster mobility after surgery, has lower risks related to
general anesthesia and adverse effects and also reduces
hospital costs. Axillary block is performed almost for
hand and forearm anesthesia. Dexmedetomidine which is
an alpha2 agonist decreases secretion of norepinephrine
at pre-synaptic peripheral receptors and so reduces the
transmission of pain signals and has independent inhibitory
effect on nerve action potential.
Objectives: Purpose of this study was to examine the
effects of adding dexmedetomidine to lidocaine in axillary
block to improve quality of axillary block.
Methods: This study was performed as a randomized,
double-blind clinical trial on 40 patients scheduled for hand
and forearm surgery with axillary block. patients were divided
randomly into two groups of 20: In the first group 39
cc of lidocaine 1% plus 1cc of normal saline were administered
and the 2nd group received dexmedetomidine 1 cc
(100 μg) in addition of 39 cc of lidocaine 1%. The onset
and persistence of sensorimotor block and hemodynamic
changes including heart rate, systolic and diastolic blood
pressure before, during and after surgery were compared.
Sensory block was assessed with pinprick test and motor
block of radial, ulnar, median, and musculocutaneus nerve
were evaluated with thumb abduction, thumb adduction,
thumb opposition and elbow flexion separately.
Results: Onset of sensory and motor block was similar
in both groups, but the persistence of sensory and motor
block and analgesia in the dexmedetomidine group
were significantly longer than the other group (P<0.05).
Conclusions: The results of this study showed that
adding dexmedetomidine to lidocaine in axillary block did
not alter the onset of sensory and motor block, but sensory
and motor block length and analgesia increases. Despite
differences in hemodynamic responses between the two
groups, these changes were not clinically important |
