DESCRIPTION
To compare HR, SBP, DBP, MAP, SPO2 & ETCO2 across groups -In intra-op & Post-op stages at different time intervals -From the base line (Pre-op: for Intra-op & EOC: for Post-op) To study (across groups) Adverse events (Tachycardia, Brady-cardia, Hypertension, Hypo-tension & Nausea Vomiting) Shivering and sedation

Objectives:
• To compare HR, SBP, DBP, MAP, SPO2 & ETCO2 across groups
-In intra-op & Post-op stages at different time intervals
-From the base line (Pre-op: for Intra-op & EOC: for Post-op)
• To study (across groups)
- Adverse events (Tachycardia, Bradycardia, Hypertension, Hypotension & Nausea Vomiting)
- Shivering and sedation
Total: 120 Patients
Group K=30
Intravenous ketamine
Group C=30Group KC=30
Group P=30
Normal saline
Intravenous clonidine

• Statistically significant difference in the occurrence of shivering across group
• 75.9% of people: out of 120 ; 27.5% of people had extreme shivering(>=3)
• 66.67% people out of 30 in group P had experienced extreme shivering
• Moderate or No Shivering: 86.67% in group KC; 76.67% in Group K and 93.3% in group C
• Intravenous clonidine: Most useful in prevention of post anesthetic shivering as compared to other drugs
• Placebo seems to be the least effective in the prevention of shivering in comparison to others

DOS Duration of SurgeryAdverse events:
•Tachycardia happens when intra-operative Heart Rate rises above 100
•Bradycardia happens when intra-operative Heart Rate falls below 60

Score Shivering Sedation
0 None -
1 peripheral vasoconstriction but no visible
shivering fully awake and oriented
2 Muscular activity in only one muscle
group Drowsy
3 Muscular activity in more than one
muscle group but not generalized Eye closed but responds to commands
4 Shivering all over the body Eye closed but responds to mild physical stimulation.
5 - Eye closed and not responding to mild physical stimulation.
