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.

Purpose: The study was designed to identify the factors that influence the length of stay of elderly people in the recovery room. Methods: The design of the study was descriptive correlation. The subjects were 196 general anesthesia patients. The data were analyzed by SPSS/WIN 17.0 program. Results: The average length of stay in the recovery room was 62.62 minutes. The length of stay in the recovery room was influenced by age (27.50%); number of diseases (12.97%) and albumin level (6.75%). Other related post operative factors (30.98%) were abnormal ABGA, shivering, PAR score, pain, arrhythmia, amount of bleeding, cardiovascular complication, hypertension and delirium. Those factors explained 78.2% out of the total variance of the length of stay. The strongest effector was the abnormal ABGA (${\beta}$=.226) and then shivering (${\beta}$=.222). Conclusion: The influencing factors should be assessed and monitored for the aged before and after surgery. Further research is needed to find the exact factors for ICU transfer elderly from recovery room and emergency surgery target.

Purpose: This study examined the effects of music therapy on pain, anxiety and length of stay of patients undergoing laparoscopic hysterectomy in the postanesthesia care unit (PACU). Methods: Sixty patients who received laparoscopic hysterectomy under general anesthesia from a PACU in a university hospital located in Cheonan city participated in this study. The experimental group (n=30) was offered the option to listen to their preferred music by using MP3 players and headphones for 30 minutes. The control group (n=30) received routine postoperative nursing care. Visual analogue scale was used to measure participants' pain and anxiety, length of stay in the PACU was examined by using their medical records. Data were collected from December 2013 to February 2014 and analyzed by descriptive statistics, ${\chi}^2$-test, Fisher's exact test, and independent t-test using SPSS version 21.0. Results: The result showed that the level of post-operative pain (t=2.44, p=.018), anxiety (t=2.37, p=.021), and the length of stay in PACU (t=3.06, p=.004) significantly decreased in the experimental group as compared to the control group. Conclusion: This study indicated that music therapy with the patients' preferred music showed positive effects. Therefore, it can be used as a therapeutic intervention for postoperative pain management of patients with laparoscopic hysterectomy.

Purpose: The objectives of this study were to assess the influence of family presence in the PACU (Post Anesthesia Care Unit) on anxiety, emergency delirium, pain and length of stay in the recovery room for elderly patients undergoing surgery for which general anesthesia has been used. Methods: The study was a nonequivalent control group pre-post test design. Eighty elderly patients over 65 years who underwent surgery under general anesthesia were recruited. Forty were assigned to the experiment group, patients together with a family member and 40 to the control group, with no family member present. Patients' anxiety, emergency delirium, pain and length of time in the recovery room were evaluated at 10 minute and 30 minute after arrival in the PACU. Results: Patients with family members in the PACU showed significantly decreased levels of anxiety at 10 and 30 minutes and significantly lower levels of emergency delirium and pain at 30 minutes. However there was no difference between the 2 groups for length of time in the recovery room. Conclusion: The results of this study indicate that being with family members in the PACU after surgery under general anesthesia is effective for reducing elderly patients' anxiety, delirium and pain during time in the recovery room.

Purpose: This study compared the effect of music and noise blocking on the vital signs, postoperative pain, analgesic use, length of stay in the Post Anesthesia Care Unit (PACU) and satisfaction after a laparoscopic colectomy. Methods: This randomized controlled trial was performed in a 555-bed National Cancer Center, from February 13 through May 31, 2012. Subjects consisted of 69 patients who underwent a laparoscopic colectomy under general anesthesia, and were recruited by informed notices. The inclusion criteria were patients between the ages of 35-75, with an American Society Anesthesiologist physical classification I or II. The subjects were randomly allocated to three groups; music therapy group (MTG), noise blocking group (NBG) and control group (CG). Collected data were analyzed using Repeated measures ANOVA, one-way ANOVA and Kruskal-Wallis test through IBM SPSS (Version 19.0). Results: There were no significant differences in vital signs among the three groups. Postoperative pain in MTG (p<.05) and NBG (p<.05) was significantly decreased compared to CG. The amount of analgesics (p=.030) and length of stay at PACU (p=.021) in MTG was significantly decreased compared to NBG or CG; satisfaction in MTG and NBG was significantly higher compared to CG. Conclusion: Music seems to reduce postoperative pain, the amount of analgesics, and the length of stay at PACU. Therefore, music therapy is considered to be included in nursing intervention for postoperative patients at PACU.

Dentally disabled person means one who have difficulty in cooperating voluntarily with a dentist for routine dental care. Seoul National University Dental Hospital (SNUDH) Dental Clinic for Disabled has worked for them under outpatient anesthesia concept. The aim of this study was to determine the anesthetic characteristics of the patients attending for dental treatment at SNUDH Dental Clinic for Disabled in order to establish better future treatment plans. The data were drawn from the patients who visited SNUDH Dental Clinic for Disabled from January 1999 to October 2002. Total 93 dental treatments for 83 patients were enrolled in this study. Most patients had mental retardation and the conservative treatments were carried out under general anesthesia. Thiopental and vecuronium were mostly used for induction agent and neuromuscular blocker, respectively. Enflurane, with oxygen and nitrous oxide, was mostly used to maintain the anesthesia. Mean total anesthetic time was $164.4{\pm}57.2$ minutes and mean duration at the post-anesthetic care unit was $106.2{\pm}50.5$ min. Serious postoperative complications were not observed. These results showed our successful anesthetic outcomes without any severe side effect or complication and the needs of more outpatient centers for dental care for disabled.
