Purpose
This study is a prospective observational study that analyzes the factors affecting and the incidence of postoperative delirium in elderly patients under general anesthesia.
Methods
The study enrolled 193 elderly patients who entered the recovery room after surgery under general anesthesia in a certified tertiary hospital. Data were measured twice-first, before surgery and, second, 30 minutes after the patient entered the recovery room-using the Korean Nursing Delirium Screening Scale. The data were analyzed using x ² tests, the independent t-test, and logistic regression from SPSS 22.0.
Results
The incidence of delirium in elderly patients after surgery under general anesthesia was 13.0% (25 of 193 patients). The incidence of delirium was a significant in the following cases: elderly patient, patients who performed physical activity with assistance at pre-operation, those with lower body mass index, those with lower body weight, those with long operative times, and those with high preoperative pain scores. The occurrence of delirium was 16.57 times higher in the presence of comorbidities, 5.74 times higher when hospitalization occurred through the emergency room, and 3.99 times higher when the number of catheters was high.
Conclusion
Screening for early delirium in the recovery room is important, and it can provide basic data for early nursing intervention in patients suffering from postoperative delirium.

PURPOSE
This study sought to examine the relationships among patient's stress, pain, and nursing needs in the recovery room after surgery that was performed under general anaesthesia.
METHODS
Participants were adult patients aged 20 to 64 years who underwent surgery under general anesthesia from February 5, 2018 to March 9, 2018. A survey was conducted to evaluate the participants' general demographics, stress, pain and recovery room nursing needs at a Post Anesthesia Care Unit (PACU). A total of 145 patients receiving operational treatment in Daejin Medical Center at Gyeonggi-do were recruited. Collected data were analyzed in terms of percentage, frequency, independent t-test, one-way ANOVA, and Pearson's correlation coefficient using SPSS/WIN 23.0 program.
RESULTS
Among the PACU nursing needs environmental and educational nursing needs were the highest. In addition, patients with underlying diseases experienced more post-operational stress and had fewer educational nursing needs in the recovery room. Therefore, Aggressive pain management and emotional recovery room nursing needs should be provided in the PACU.
CONCLUSION
It is necessary to build a comfortable environment for the patient as well as protect patients from infection and guarantee their privacy. In order to reduce patients' stress, educational nursing needs in the recovery room should be provided before an operation.
