Abstract
The present study was deliberate to evaluate the effects of dexmedetomidine infusion on the requisite of isoflurane concentration to lower systolic blood pressure below 30% of baseline values, quality of oligaemic surgical field, and awakening time in patients undergoing middle ear surgery.

The age of the patients is from 20-50 years. The surgery time ranges from 1 to 2 hours. The base line in both groups is observed in same range. After induction heart rates is observed in Group I as 65-81 beats per min and in group II as 64-82 beats per mins. After Extubation is observed slightly higher side on both groups. The Isoflurane required is more in group II to reduce the systolic blood pressure. In group I patients 18 cases showed minimum bleeding where as in group II 7 patients had found. In group I patients 3 cases are seen with diffuse bleeding and in group II 15 cases are found.

Dexmedetomidine infusion was harmless to deliver reduction haemorrhage for worthy surgical field and improved imagining for middle ear micro surgery keeping the haemodynamic differences within the physiological range. It also condensed the prerequisite of isoflurane and retrieval from anaesthesia was complete and smooth.
