Abstract
Background:-Delirium is a common clinical condition in patients admitted to intensive care unit (ICU).It is also known as acute confusional state, and is an organic cause of decline from a previously baseline level of mental function.It is classified as hyper-active and hypo-active delirium. Hypo-active delirium is characterised by apathy, decreased responsiveness whereas hyper-active delirium is characterised by agitation, restlessness and emotional liability. Aim:-To assess delirium in patients admitted in a medical ICU. Material and methods:-This cross-sectional study was carried out in the medical ICU of AVBR hospital, JN medical college of DMIMS(DU). A total of 36 patients with delirium were included in the study. The eligible cases were first subjected to Richmond Agitation–Sedation Scale (RASS).In the RASS assessment, the subjects who attained the score of -3 or more were subjected to CAM-ICU and delirium positive or negative patients were diagnosed. Results:- Predominant factors causing delirium in patients were old age, sepsis with multi-organ failure, patients who were prescribed with sedatives and other infectious as well as non-infectious aetiologies.Out of 36 critical care unit patients having delirium, 77.7% of patients were above 60 years of age contributing to the majority. Sepsis along with multi-organ failure is the predominant infective aetiology causing delirium in about 72.2% of the patients followed by other causative factors. Conclusion: Delirium is commonly encountered acute neurological disturbance in critical care ICUs. It adversely affects short term outcomes and long term sequels. Critical care clinician should be aware of common risk factors like overzealous sedative use, infections and age.
