This study is a descriptive investigation for understanding factors influencing the length of stay in the postanesthesia care unit of elderly patients. Retrospective investigation was conducted on 300 patients aged 65 or older among those who had received an operation under general anesthesia and treated in postanesthesia care unit of hospital C located in Gyeonggi-do, from January 1 to December 31, 2014. The patients' average postanesthesia care unit stay was found to be 48.4 minutes and the 30-59 minute section accounted for the highest part with 58.0%. The postanesthesia care unit stay time according to intra-operative factors showed significant differences depending upon muscle relaxants, transfusion, ABGA, body temperature and total hours under anesthesia. Concerning the post anesthesia care unit stay length according to post-operative factors, significant differences were observed depending upon complications, PCA device, and circulatory drug use. In order to find out factors influencing the post anesthesia care unit stay length, the multiple regression analysis was conducted. As a result, the circulatory drug use and intra-operative lower body temperature were found to have an effect on the post anesthesia care unit stay length with the total explanatory power of 13%. Based on these findings above, it is deemed helpful to carefully monitor factors related to the post anesthesia care unit stay length and provide swift response accordingly for shorter post anesthesia care unit stay time of elderly general anesthesia patients.
