Sleep quality assesment pre and post operative surgery

Eppworth sleepiness test (ESS) The ESS subjectively measures sleepiness as it occurs in ordinary life situations.It can be used to screen for excessive sleepiness or to follow an individual's subjective response to an intervention. Eight situations are described on a questionnaire: * Sitting and reading * Watching television * Sitting inactively in a public place * Riding as a passenger in a car for one hour without a break * Lying down to rest in the afternoon when circumstances permit * Sitting and talking with someone * Sitting quietly after lunch without alcohol * Sitting in a car as the driver, while stopped for a few minutes in trafficEach situation receives a score of 0 to 3, which is related to the likelihood that sleep will be induced: * 0 = would never doze * 1 = slight chance of dozing * 2 = moderate chance of dozing * 3 = high chance of dozing Total ESS score can range from 0 to 24, with higher scores correlating with increasing degrees of sleepiness
