ABSTRACT
Background & Objectives: To evaluate the effects of clonidine as an
adjuvant to local anesthetic mixture, for caudal anesthesia, in pediatric
patients undergoing sub umbilical surgeries. Material & Methods:
Fifty ASA –I and II, children from age group of 1 year to 6 years, from
either sex, were selected for study. Patients were randomly divided
into two groups of 25 each : Clonidine group received : Local
anaesthetic mixture + Inj. Adrenaline + Inj. Clonidine (1μg/kg). While
in Control group received: Local anaesthetic mixture + Inj. Adrenaline
through caudal epidural route. Onset of blockade, hemodynamic and
respiratory parameters, sedation and postoperative analgesia were
observed. Results: Onset of sensory and motor blockade was
significantly earlier in Clonidine group (sensory blockade: 1.32±0.39
minutes, motor blockade : 1.92 ± 0.31minutes), than control group (sensory blockade : 3.02 ±
0.36 minutes, motor blockade : 3.70 ± 0.45 minutes) (‘p’<0.05). Peak effect was achieved
significantly earlier in Clonidine group(sensory : 4.76±0.50 minutes, motor : 8.02 ±0.6
minutes ), than control group(sensory : 8.46 ± 0.91minutes, motor: 10.96 ±0.78 minutes).
(‘p’<<0.05). Duration of post operative analgesia was significantly longer in Clonidine group
(444 ± 54.77 minutes), as compared to Control group (177 ± 36.66 minutes). Conclusion: we
conclude, clonidine as an adjuvant o local anesthetic solution, for caudal block significantly
shortens time for onset and peak effect for sensory and motor blockade, prolongs duration of
analgesia.
