This study was designed to investigate the effects of information by using cartoon on preoperative anxiety of children following tonsillectomy. The subjects were 30 children aged between 7 and 12 who were hospitalized at C university hospital for undergoing tonsillectomy from December 20, 1996 to August 14, 1997 Sixteen of them were assigned to the experimental group, while fourteen subjects to the control group. The data were collected through preoperative state anxiety, pulse rate, pain before and after giving information by using cartoon. The results were as follows : 1. Preoperative state anxiety increased in both groups (P=0.0348). No significant difference found between experimental and control group. But preopertive anxiety in experimental group was apt to increase less than that in the control group. 2. Pulse rate didn't make significant difference within and between groups. 3. Pain increased in both groups (P=0.0001). No significant difference found between experimental and control group. 4. Experimental group between the aged 7 and 9 decreased preoperative state anxiety, but experimental group between the aged 10 and 12 increased preoperative state anxiety after treatment(P=0.0298). These findings may indicate that the information by using cartoon is effective in children between the aged 7 and 12.

Evaluation of heart function is of importance in assessing the results of valvular heart surgery. Information on volume and functional change of heart chamber can be obtained by cardiac catheterization and echocardiography. We studied 41 patients with mitral stenosis[MS] and 23 patients with mitral regurgitation[MR] using M-mode echocardiography before and after mitral valve replacement[MVR] at Pusan Paik Hospital. Preoperative cardiac catheterization was available in 56 cases, and the results were obtained as follows. 1. In patients with MS, preoperative average LV end-diastolic dimension[EDD] and end-systolic dimension[ESD] were remained within normal range, but postoperative EDD and ESD were significantly decreased[P<0.01]. The preoperative and postoperative LV ejection fraction[EF] were remained within the normal range and no significant change[P>0.05]. The preoperative left atrial dimension[LAD] was enlarged considerably above normal[P<0.01], but was significantly decreased after surgery[P<0.001]. The preoperative LV posterior wall thickness[PWTh] was within normal range, and no significant change after surgery[P>0.05]. 2. In patients with MR, preoperative average end-diastolic dimension[EDD] and end-systolic dimension[ESD] were significantly greater than normal[P<005], but postoperative EDD and ESD were significantly decreased[P<0.01]. The preoperative LV ejection fraction[EF] and fractional shortening[FS] were within normal range, and no significant change after surgery[P>0.05].The preoperative left atrial dimension[LAD] was enlarged considerably above normal [P<0.01], but was significantly decreased after surgery[P<0.001].The preoperative LV posterior wall thickness[PWTh] was within normal range, and no significant change after surgery[P>0.05].

Purpose: The purpose of this study was to ascertain the effects of preoperative information on postoperative state anxiety, plasma cortisol, and pain for patients under total knee arthroplasty, and to provide generic data with nursing intervention for total knee arthroplasty. Methods: Data were collected from 34 patients who had total knee arthroplasty from January 3, 2003 to January 15, 2004. An experiment group of 17 patients was provided with pre-operative information prepared by the researchers; a control group of another 17 patients was provided with general information. Data were analyzed through Chi-squared test, t-test, paired t-test and ANCOVA using SPSS WIN 11.0. Results: There was no significant differences between the experiment group and the control group in post operative state anxiety(p=.612). However, there was statistically a significant difference between the above two groups in post operative plasma cortisol(p=.012). There was a statistically significant difference between the above two groups in post operative pain(p=.041). Conclusion: According to the results of the study, the authors concluded that the preoperative information for patients under total knee arthroplasty had the effect on the decrease of postoperative plasma cortisol and pain.

Purpose: The purpose of this study was to determine the effect of preoperative guidance and operating room environment experience using virtual reality on increasing satisfaction with information and reducing anxiety in preoperative patients undergoing general anesthesia and local anesthesia. Methods: A non-equivalent control group quasi-experimental design was employed. The participants were 80 surgical patients from 4 wards (40 experimental group and 40 control group) of the general hospital located in Gyeonggi-do. Data collection was conducted from June to November 2023 after completing the control group survey in January 2023. Data were analyzed using Chi-square, t-test, and Mann-Whitney U test using SPSS 23.0 program. Results: Satisfaction with preoperative information was higher in the experimental group than that of the control group. Additionally, anxiety related to surgery in the experimental group was significantly lower than that of the control group. The preoperative state anxiety score in the experimental group was not significantly lower than that of the control group. Conclusions: These results suggest that providing patient education and information using virtual reality technology can not only alleviate patients' anxiety related to surgery, but also have the potential to be used as an effective intervention to improve positive patient experiences.

Every anesthetic begins with preoperative evaluation. This meeting of patient and anesthesiologist allows for an exchange of information, an assessment of physical status, and the formulation of an anesthetic plan. The aim is to have the patient in the best possible condition, both mental and physical, prior to surgery. The preoperative visit is as important as any aspect of introperative management in providing a safe, effective anesthetic.

The purpose of this study was to examine the effect of self-care of abdominal surgery patients in surgical intensive care unit after offering preoperative nursing information. This study worked out nonequivalant control group post test only design as suspected experimental study. This subjects of the study were 45 patients, 23 in experimental group and 22 in control group. This study was carried at a university hospital in Taegu between January 12, 1999 and March 13, 1999. The experimental group was supplied with preoperative nursing information and the control group received routine care in ICU. The measuring tools of this study were assessment of the self-care role behavior. The data were analyzed by SPSS computer program, $x^2-test$ and t-test and ANOVA were utilized for testing the difference between the experimental and the control group. The hypothesis was examined by t-test. The result of this study are summarized as follows ; 1) The hypothesis, 'The experimental group will show a higher level of self-care than the control group' was accepted(t=-8.958, p=.000). 2) We could not find any meaningful relation about general characteristics and disease associated characteristics between the experimental and the control group. 3) The self-care behavior scores according to the general characteristics and disease associated characteristics show significant statistical difference by economics status (p=.033). 4) The rate of self-care behavior scores of each questionnaire are below average in the questions that request active activity to prevent postoperative complications From the result of this study, the self-care of the experimental group was higher than those of the control group, and the nursing information can be regarded as an effective nursing intervention for preoperative patients.

Purpose: Purpose of this study was to identify the effect of structured information on immediate preoperative anxiety and uncertainty for women undergoing total laparoscopic hysterectomy. Methods: Sixty women who were admitted for total laparoscopic hysterectomy were recruited at a university hospital in Gyeonggi-do from June to October 2014. Thirty women were assigned to either the experimental or the control group. Women in the experimental group were provided structured information, which consisted of visual and auditory materials about surgical preparation and process, practical experience on devices such as IV-PCA pump and Inspiro-meter and actual experience on route to go to the operating room. State-anxiety, uncertainty, and blood pressure and pulse rate as biological indicators were measured before and after the intervention to examine the effect. Results: Significant group differences were found on state anxiety, uncertainty, including ambiguity, inconsistency, and unpredictability at the holding area. There was a significant difference on pulse rate in the operating room between the two groups. Conclusion: Findings demonstrated that the structured information provided for women undergoing laparoscopic hysterectomy preoperatively was effective on immediate preoperative anxiety and uncertainty. Nurses may contribute to decreasing patients' anxiety and uncertainty by utilizing this structured information preoperatively.

This paper presents an overview of automated robotic system for skull drilling, which is performed to access for some neurosurgical interventions, such as brain tumor resection. Currently surgeons use automatic-releasing cranial perforators. The drilling procedure must be performed very carefully to avoid penetration of brain nerve structures; however failure cases are reported. The presented prototype system utilizes both preoperative and intraoperative information. Preoperative CT image is used for robot path planning. A NeuroMate robot with a six-DOF force sensor at the end effector is used for intraoperative operation. Intraoperative cutting force from the force sensor is the key information to revise an initial registration and preoperative path plans. Some possibilities are verified by path simulation but cadaver experiments are required for validation of this prototype.

Purpose: This study was done to verify the effects of information using photographs on preoperative anxiety of children and their parents. Methods: Participants were 48 hospitalized children and their parents (48 pairs). In the experiment group (18 pairs) photographs were used with the children and parents to provide information before the child underwent an operation. Children and parents in control group (30 pairs) received regular care. Anxiety of children and their parents was measured using both a self-report and physiologic responses (heart rate and blood pressure). The data were analyzed using the SAS program. Results: Compared with the control group, self-reports of the experimental group indicated a significant difference in subjective anxiety. However, there was no decrease in physiologic anxiety as shown by heart rate and blood pressure in those in the experimental group as compared to the control group. Conclusions: Preoperative information using photographs were shown to be an effective method to reduce anxiety of children and their parents.

Background : The purpose of this research was to evaluate the appropriateness of preoperative hospital days in a tertiary care hospital and to examine the reasons of the inappropriateness, so as to provide basic information and policy for enhancing appropriateness of preoperative hospitalization and benefit of patients and hospital. Methods : The subjects of the research were the 344 patients who received operation among discharged patients during January, 1996 in surgical departments including general surgery, neurosurgery, orthopedic surgery, plastic surgery and ophthalmology. Their medical records were reviewed and appropriateness of hospital days was evaluated by the Appropriateness Evaluation Protocol. Result : The results of evaluating the appropriateness of preoperative hospitalization showed that inappropriate hospital days were 80.8%. The reasons of inappropriate hospital stays were the tests or preparation which could be done in outpatient basis' followed by 'possible tests or preparation on the operation day' and 'cancelation of operation'. Conclusion : In order to shorten the inappropriate preoperative length of stay, it is recommended that lengthening of laboratory running time and doing most of tests necessary for operations on the outpatient basis prior to admission should be considered. In addition, the operation at the same day of hospitalization and usage of day surgery should be encouraged. Finally there should be changes in the inpatient management system and attitudes and behaviors of surgeons to shorten unnecessary preoperative and maximize the benefit for patients and hospital.
