AbstractBackground : Hypotensive anaesthesia is extensively used during surgery, particularly maxillofacial procedures. Hypotensive anaesthesia reduces blood loss during surgery by rendering the operative field bloodless. Normal blood pressure (BP) during surgery indicates skillful anaesthesia since organ perfusion is preserved. Achieving optimal hypotension is a skill, as excess BP reduction can be dangerous due to diminished circulation to organs like the brain, heart, and kidneys.
Materials and methods: AComparative study. 52 Indian phenotype patients were randomly selected from a table and divided into two groups of 26. Group D = dexmedetomidine (1 μg /kg diluted in 10 mL 0.9% saline administered over 10 minutes before anaesthesia, followed by 0.2–0.7 μg/kg/hour). Group P = propofol (100–150 μg/kg/hour). Mean arterial pressure (MAP) and hemodynamic stability were maintained by titrating infusions.
Results: In our research, neither hypotension nor bradycardia required medication. Group D had lower heart rate and blood pressure than group P. Group D awoke faster than group P. The usual dosages of dexmedetomidine and propofol for hypotensive anaesthesia are 0.2 0.04 μg/kg/hour and 140 41 μg/kg/hour, respectively. In India, little doses may not create issues.
Conclusion: In our investigation of the Indian population, both dexmedetomidine and propofol produced the necessary hypotension in ENT surgery patients to reduce blood loss and increase operational field vision. MAP was lower in dexmedetomidine than propofol, but not significantly. Higher propofol Ramsay sedation scores suggest stronger sedation than dexmedetomidine, making it a superior candidate for hypotensive anaesthesia
