1) The study compared the effects of intravenous ketamine, clonidine, ketamine+clonidine, and saline on 120 patients over various intra-op and post-op time intervals. 2) Key parameters like heart rate, blood pressure, oxygen saturation were analyzed and found to differ significantly between groups except in pre-op. Adverse effects also differed significantly between groups. 3) Intravenous clonidine was found to be most effective in preventing post-op shivering compared to other treatments. Ketamine+clonidine and saline groups had more stable vital parameters intra-op compared to ketamine and clonidine alone.

Total: 120 Patients Group K=30 Group C=30 Group KC=30 Group P=30 Intravenous ketamine Intravenous clonidine Intravenous ketamine & clonidine Normal saline 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
