Development of Delirium in Patients Undergoing Open-Heart Surgery

Overview

Malnutrition is a prevalent issue among patients undergoing cardiac surgery. This can lead to delirium risk factors, including postoperative functional and cognitive impairment. Assessing the patient's nutritional status before open-heart surgery may decrease the incidence of delirium and the psychological and physiological problems associated with it. The objective of this study was to examine the relationship between nutritional status and the incidence of postoperative delirium in patients who have undergone open-heart surgery.

Upon examining the literature, it was found that the incidence of delirium after open heart surgery ranged from 3% to 70% (Tomakin et al., 2020). Postoperative delirium has numerous risk factors, including predisposing and accelerating factors. Predisposing risk factors comprise malnutrition and electrolyte imbalance, cognitive impairment, depression, and other psychiatric disorders such as dementia (Velayati et al., 2019; Wilson et al., 2020). This study aims to investigate the relationship between the nutritional status of patients undergoing open heart surgery and the development of postoperative delirium. The study will be conducted in the Cardiovascular Surgery Intensive Care Unit of Bursa Uludag University Health Application and Research Centre Hospital between September 2023 and February 2024. Data will be collected using the Personal Information Form, Nutritional Risk Screening Score 2002 (NRS-2002), Delirium Risk Assessment Form, Visual Analogue Scale for Pain Levels, Richmond Agitation Sedation Scale, Glasgow Coma Scale, and Confusion Assessment Scale in Intensive Care Unit.
