ABSTRACT
Aims and Objectives:To compare epidural ropivacaine 0.75% alone
and Ropivacaine 0.75% with alpha 2 agonists. Variables like block
characteristics, hemodynamics, sensory and motor recovery, side
effects are analysed. Materials: With Institutional ethical committee
clearance, clinical Study conducted at R.L.J.H, Kolar. After obtaining
informed written consent,90 patients of(American Society of
Anaesthesiologists) ASA Grade I and II in age group 18 to 55 years, of
either sex, posted for elective lower abdominal and lower-limb surgeries
were selected. Methods:Patients were randomly allocated into 3 groups
of 30 each.Epidural block was administered.Patients in group“R” received 19ml 0.75%
ropivacaine with 1ml of normal saline. Group “RC” patients received 19ml 0.75%
ropivacaine with 75microgram(mcg) clonidine while patients in group “RD” received
19ml0.75% ropivacaine with 75 mcg dexmedetomidine. Block characteristics like onset of
analgesia, maximum level of sensory blockade, complete motor blockade, hemodynamics,
time to two segment regression, time for rescue analgesia, time to complete motor recovery,
side effects were analysed. Results: Results showed that onset of blockade is faster when
additives are added like clonidine and dexmedetomidine. Time for two segment regression
was 30-35minutes earlier in Group “RC”.(R
