"Comparison of recovery of mental and motor skills in patients receving either intravenous propofol or dexmedetomidine infusions as part of balanced general anaesthesia:A prospective randomized single-blind study"

Phase 4

Not yet recruiting

Brief Summary: Immediate post-operativerecovery forms a prerequisite for any successful anaesthetic procedure-especially so in day care surgeries. The DSST, primarily measures visual recording andincludes a motor component. It is an useful indicator of changes in sensoryprocessing performance induced by psychoactive tests.

There are only a few studies comparingpsychomotor effects of dexmedetomidine and propofol. We hypothesise that a goodDSST score indicates a better recovery from anaesthesia which can translate toan early discharge from a limited bed available Post Anaesthesia Care Unit(PACU) to postoperative ward. Therefore, we would like to compare the abovedrugs using DSST as a measure of psychomotor recovery surgeries under generalanaesthesia
