Relationship between Preoperative Diabetes and Delirium in Patients Undergoing Neurosurgery

Background: One of the surgeries that led to the hospitalization of the patient in the ICU and the creation of postoperative delirium (POD) is neurosurgery. We conducted this study to investigate the relationship between preoperative diabetes and delirium in patients undergoing neurosurgery in the ICU. Methods: In this study, before performing the surgery, the checklist designed by the researchers was completed by interviewing the patients, and the necessary information was completed through clinical examination, interviewing the patient, and studying the documents in the patient's file. Then, the research tool to identify POD was reviewed and completed on a daily basis from the time the patient entered the ICU until the time the patient was discharged. In order to investigate delirium, the researchers conducted a clinical examination, observed the patient's clinical record, and completed the CAM-ICU-7 questionnaire. After completing the research tools, the data were entered into SPSS software, and their analysis was done using version 18 data analysis. Results: Results showed, in patients with diabetes, the prevalence of POD in patients with a history of smoking, high creatinine, agitation, and intubation was higher than in other patients (P value < 0.05). Also, the prevalence of POD diabetic patients was 54 (38.57%), which is 38 (54.28%) in diabetic patients and 16 (22.85%) in non-diabetic patients. Conclusion: Considering that a significant relationship was observed between diabetes and the prevalence of POD, it is important to carry out the necessary prevention in this field.
