Pak J Med Sci Jan ;23(2):188-92.

Objective: To assess a multi-component intervention to prevent post operative delirium after open-heart surgery. Method: This is an experimental-analytic study which assessed 32 patients 45 to 70 years of age after open-heart surgery in to 16 member groups (case and control). From second days after operation until three days later, by 6 risk factors: cognitive¸ visual and auditory impairment¸ immobility, dehydration and sleep deprivation were assessed and a standard protocol was used for case group. Incidence of delirium was determined by clinical interview; based on DSM-IV-TR; twice a day (morning and evening). Result were analyzed by t-test and S- plus. Results: The median of total number of risk factors and immobility in case group had a significant reduction in comparison to control group. There were trends towards reduction in other risk factors and incidence of delirium. Conclusion: Primary prevention of delirium is probably the most effective treatment strategy.
