Abstract

Objective:The objective of the present study is to determine the frequency of delirium and the associated factors in patients undergoing open heart surgery.Study Design: Descriptive cross sectional study.Place and Duration of Study: Armed Forces Institute of Cardiology and National Institute of Heart Disease, from October 2016 to December 2016.Materials and Methods:A descriptive cross sectional study was conducted on 328 patients, who underwent elective open heart surgery at intensive care unit of AFIC/NIHD, over 3 months spanning from October to December 2016. The patients who underwent elective coronary artery bypass graft (CABG) surgery during the specified study period are included in inclusion criteria and age of over 18 years. While patients with the history of psychiatric illness were excluded.Samplings were performed by non-probability consecutive sampling technique. Patients were assessed for delirium byusing the DSM IV Criteria for diagnosis of Delirium. Chi- square statistics and Pearson correlation were used as a test of significance.Results: The frequency of immediate post surgical delirium was found to be 5.0%. The patients mean age was found to be 55 (53±14) and most frequent age group was >50 yearsi.e. 200 (61.0%) while number of patients in <50 years were 128 (39.0%). Among these patients, 245 (72.0%) were male and 95 (28.0%) were females. Of these patients, 246 (72.0%) had coronary artery bypass graft (CABG) and 60 (18.0%) underwent valve repl...Conclusion: Diagnosis of delirium is of greatest value; therefore, further studies are essential to clarify the risk factors because controlling them will m.....
