Feature Analysis for Evaluating the Risk of Postoperative Delirium in Pediatric Patients

<b>Background/Objectives:</b> Postoperative delirium is an acute condition commonly seen in pediatric patients. It is often observed in intensive care units for patients undergoing general anesthesia. Characteristic symptoms include disturbances of consciousness, attention, perception, or disorientation. The occurrence of delirium can be assessed using the CAPD and PAED scales. <b>Methods:</b> A single-center observational cohort studyof the 2022-2024 results was conducted. A total of 89 patients of the Pediatric Anesthesiology and Intensive Care Unit undergoing procedures under general anesthesia were included in this study. The state of delirium just after the recovery from anesthesia was assessed using the CAPD and PAED scales. <b>Results:</b> A total of 60% of patients experienced delirium taking the results according to the CAPD scale, 39% according to the PAED scale. A score indicating delirium according to both the CAPD and PAED scales was recorded in 21% of the patients examined. The results of the correlation analyses indicate a strong relationship between the CAPD and PAED scales. The feature analysis indicated there was a correlation between the occurrence of delirium and chronic disease. One of the confirmed risk factors for the development of postoperative delirium in children is postoperative pain. The experience of postoperative delirium is associated with the observation of negative postoperative behavioral changes in children within 7 days of hospital discharge. <b>Conclusions:</b> The correlation analysis showed a significant positive relationship between CAPD scale and PAED scale. The feature analysis indicated a relationship between CAPD scores and the existence of chronic diseases.
