Details |
Intervention |
DEXMEDETOMIDINE |
Dexmedetomidine was diluted in 50 ml of 0.9% saline as 2µg/ml concentration and loaded in an infusion pump. After induction of general anaesthesia and intubation, all participants received a loading dose of 0.5 ml/kg over 10 minutes & a maintenance infusion of 0.25 ml/kg/hr. Infusion was stopped during skin closure at the end of surgery. |
Comparator Agent |
Normal saline |
0.9% saline was loaded in 50 ml syringe and loaded in a infusion pump. After induction of general anaesthesia and intubation, all participants received a loading dose of 0.5 ml/kg over ten minutes & a maintenance infusion of 0.25 ml/kg/hr. Infusion was stopped during skin closure at the end of surgery. |

Brief Summary
|
After informed consent, patients fulfilling the inclusion and exclusion
criteria will be randomized to two groups by computer generated random numbers.
Pre operatively, psychomotor function of the patient will be assessed with TDT
and DSST. Trieger dot test consists of joining 30 dots with a line to form a
figure within a time limit of 60 seconds. It is analyzed by number of dots
missed, maximum distance of dots missed and average number of dots missed. DSST
consists of matching digits with their corresponding symbol within a time
limit. The digits along with the corresponding symbols will be located in a
legend given at the top of the page. 9 such digits will be assigned symbols in
the legend. It is analyzed by the number of digits correctly matched with the
corresponding symbols within 90 seconds. On the day before surgery, both the
tests will be done thrice to familiarize it to the patient and fourth test will
be taken as the baseline psychomotor evaluation for that patient. In each of these patients, after attaching the routine monitors and
recording baseline parameters, anaesthesia will be induced with Propofol (up to
2.5 mg/kg) and Fentanyl (2µg/kg). Vecuronium (0.1mg/kg) will be given in both
groups and trachea intubated after 3 minutes. Dexmedetomidine will be diluted
to 2µg/ml in a total volume of 50 ml and will be blinded against an identical
volume of saline. After intubation, each patient’s receive a loading dose of
0.5 ml/kg over 10 minutes & a maintenance infusion of 0.25ml/kg/hr.
Anesthesia will be maintained by nitrous oxide 67% in oxygen and sevoflurane
whose MAC value will be adjusted to maintain an entropy value of 40 - 60. Supplemental
fentanyl will be given as clinically indicated. Fentanyl will not be
administered within 30 min of the end of surgery. Inhalational agents and infusions will be stopped at
the time of skin closure. TDT and DSST will be conducted at intervals of 30 minutes, 60 minutes,
90 minutes and 120 minutes after the end of the surgery. The clinician
performing the postoperative psychomotor analysis would be unaware of the drug
that had been administered to the patient. |
