Brief Summary

Postoperative Cognitive Dysfunction (POCD), is a subtle decline in cognitive function characterized by impairment of memory and reduced ability to concentrate in elderly patients exposed to general anaesthesia. This prospective study aims to compare incidence and severity of POCD in two groups of patients. Group P receiving Intravenous Propofol and Inhalational anesthetic Sevoflurane. Group D receiving Intravenous Dexmedetomidine and Inhalational anesthetic Sevoflurane, Neuropsychological Test will be performed 24 hours before surgery and on postoperative day 3 and day 7.

Outcome Measures

Primary Outcomes (1)

  • Postoperative Cognitive Dysfunction (POCD) after major noncardiac surgery under general anesthesia in Propofol and Dexmedetomidine Group

    Postoperative Changes in Neuropsychological Tests Score compared with baseline preoperative Neuropsychological Test scores in both the groups.

    day 3 to day 7

Secondary Outcomes (1)

  • Recovery time from the stopping of anesthetics agents to eye opening in both Propofol and Dexmedetomidine Group

    30 seconds to 30 minutes.

Study Arms (2)

Propofol/Sevoflurane (Group P)

EXPERIMENTAL

Standard technique of induction of anaesthesia . Maintenance of anesthesia with intravenous (IV) Propofol Infusion at rate 100-150 mcg/kilogram/hour and Inhalational Anesthetic Sevoflurane during the surgery. Intervention is to titrate dosage of Propofol and Sevoflurane to maintain Bispectral Index between 40-60. Total dosage of IV Propofol and Sevoflurane uptake will be calculated at the end of surgery.

Drug: Maintainance of anesthesia with Intravenous Propofol infusion

Dexmedetomidine/Sevoflurane (Group D)

ACTIVE COMPARATOR

Standard technique of induction of anaesthesia . Maintenance of anesthesia with intravenous Dexmedetomidine Infusion at rate 1- 4 mcg/kilogram/hour and Inhalational Anesthetic Sevoflurane during the surgery. Intervention is to titrate dosage of Dexmedetomidine and Sevoflurane to maintain Bispectral Index between 40 - 60. Total dosage of IV Dexmedetomidine and Sevoflurane uptake will be calculated at the end of surgery.

Drug: Maintainance of anesthesia with Intravenous Dexmedetomidine

Interventions

The dosage of Intravenous Propofol will be titrated to maintain BIS Values between 40 -60.

Propofol/Sevoflurane (Group P)

The dosage of Intravenous Dexmedetomidine will be titrated to maintain BIS Values between 40 -60.

Dexmedetomidine/Sevoflurane (Group D)
