- DEX. I (Type: ACTIVE_COMPARATOR): Interventional:Dexmedetomidine (Precedex) 0.5µg/kg intravenous bolus once to be repeated if shivering incompletely abolished.
- DEX. II (Type: ACTIVE_COMPARATOR): Interventional: Dexmedetomidine (PRECEDEX) 0.3µg/kg intravenous bolus given once to be repeated if shivering incompletely abolished.
- DEX III (Type: ACTIVE_COMPARATOR): Interventional: Dexmedetomidine (PRECEDEX) 0.2µg/kg intravenous bolus given once to be repeated if shivering incompletely abolished.
