The purpose of this study was to elucidate the effects of inhalation method using essential oils on the preoperative anxiety of hystrectomy patients, and to provide effective and holistic nursing care to them. The research design was a nonequivalent control group non synchronized design. The data were collected from February 1 to March 31, 2002 at D Medical Center in Busan. The subjects were forty one patients that were operated on under general anesthesia for hystrectomy. They were assigned to two groups, twenty one subjects in the experimental group and twenty subjects in the control group. The tool of the Visual Analogue Scale(VAS) was used to anxiety on all patients the day before surgery and the preoperative period. Then systolic and diastolic blood pressure, pulse rate levels were measured the day before surgery and the preoperative period. The experimental group received two treatments of inhalation method using essential oils of with lavender, ylang ylang, and bergamot oil. The data were analyzed by the $X^2$ test and the independent t-test. The results of this study were summarized as follows: 1. Hypothesis 1: It has been supported that the experimental group received inhalation method using essential oils might cause lower level of the preoperative VAS anxiety than that of the control group(t=-2.93, p=.006). 2. Hypothesis 2: It has been rejected that the experimental group received inhalation method using essential oils might cause lower level in the preoperative systolic blood pressure than the control group(t=-.120, p=.905). It has been rejected that the experimental group received inhalation method using essential oils might cause lower level in the preoperative diastolic blood pressure than the control group.(t=1.766, p=.085). 3. Hypothesis 3: It has been supported that the experimental group received inhalation method using essential oils might cause lower level in preoperative pulse rate than the control group(t=5.853, p=.000). According to these results, inhalation method using essential oils can be considered an effective nursing intervention that relieves the preoperative anxiety of hysterectomy patients and stabilizes vital sign partially.

Purpose: The purpose of this study was to examine the effects of aroma-inhalation on depression, sleep, mood, and smell in stroke patients and their caregivers. Method: This study employed one group pretest-posttest repeated design. Data were collected at three time points: baseline(pre-test), 10 days and 20 days after the intervention(Post-test1 and post-test2, respectively). The sample included a total of 23 subjects. Data were analyzed by SPSS 12.0 program using repeated measure ANOVA. Results: Depression was not statistically significant difference among pre-test, post-test1 and post-test2. Sleep was improved after intervention $37.61{\pm}7.41$(pre-test), $41.22{\pm}8.26$ (post-test1), $44.33{\pm}7.67$(post-test2) (F=8.182. p=.001) Mood was significantly improved after intervention: $16.95{\pm}4.89$(pre-test), $14.89{\pm}6.31$(post-test1), $12.11{\pm}5.04$(post-test2). Smell including smell perception, discomfort due to smell and relation between age and smell was significantly improved after intervention: $2.63{\pm}1.20$ (pre-test). $2.00{\pm}1.16$(post-test1), $1.63{\pm}.96$(post-test2) (F=6.176. p=.006) in smell perception, $2.50{\pm}1.10$ (pre-test). $1.81{\pm}.91$(post-test1), $1.19{\pm}.40$(post-test2) (F=12.26. p=.000) in discomfort due to smell and $3.53{\pm}1.18$(pre-test). $2.59{\pm}1.46$(post-test1), $2.53{\pm}1.33$(post-test2) (F=4.148, p=.025) in relation between age and smell. Conclusion: The results suggest that aroma-inhalation may have an effect on sleep, mood and smell and can be effective nursing intervention to increase the relaxation in stroke patients and their caregivers.

Many studies in recent decades have revealed that olfactory stimulation by perfume or malodor inhalation exerts various psychological and physiological effects on humans. The most recent studies have examined the electrophysiological response of olfactory stimulation on the activity of human cortical nerve cells. The purpose of this current study is to quantitatively analyze what changes occur in the alpha activity in healthy participants (N=12) on olfactory stimulation using two types of odors (acacia and butanol). Exposure to the odor of acacia perfume was associated with a significant increase (66.7%) in alpha activity when compared with that of the no-odor background EEG. Exposure to the odor of butanol was associated with a significant reduction (33.3% to 41.7%) in EEG alpha activity when compared with that of the no-odor control. The results of this study demonstrated the potential to alter the cerebral cortex activity by olfactory stimulation. The results also suggest that olfactory perception has stimulatory effects on the function of the nervous system. In other words, it could be concluded from this study that inhalation of olfactory stimulation affected brain wave activities and mood states. Further research is needed to completely understand and describe the electrophysiological effects of different odors on the central nervous system.

Objective : Essential oil inhalation and He-Ne laser treatment has become increasingly available in children with nasal diseases. But the reports on the effect and prognosis have been poor. In this study, we analyzed the treatment effect, recurrence rate and the degree of recurrent symptoms. Materials/Methods: 23 children(2-10 year-old) with nasal diseases, who received essential oil inhalation with He-Ne laser treatment at least 10 times in our hospital from January 1st 2001 to December 31th 2002 were studied. Result : Ten cases are male & thirteen cases are female. The average of age was 4.91 year-old. The most frequency symptoms are nasal discharge (82.6%), nasal obstruction (78.3%), cough (47.8%), secretion sound (39.1%), sneezing (17.4%). Average numbers of treatment period, interval and treatment times are 71.79 days, 4.06 days, 18.13 times respectively. Of the 23 children, 14 children were in 'all symptom improved' at the remedial ends, and 22 children relapsed. In the degree of recurrent symptoms, 15 children were in 'more improved then before-treatment and not equal to directly remedial ends'. No case was in 'worse than before-treatment'. The final result of treatment, 6 children keep the degree of remedial ends, on the other hand 17 children are not. Conclusions : Even though, the recurrence rate was high, this combined treatment improve nasal symptoms. The final assessment is good, when the treatment-result is good, when the treatment interval is regular and when parent's are cooperative. If the symptoms continue a whole year, the result is not so good.

Objectives : The purpose of this study was to investigate the efficacy of inhalation therapy using Zizyphus jujuba var. spinosa blended oil and spa therapy on stress in adults. Methods : The study design was a double blind, randomized, single center clinical trial. A total of 30 volunteers who were highly stressed and were over 9 points on POMS(profile of mood states) participated in this study. Inhalation therapy using Zizyphus jujuba var. spinosa blended oil and spa therapy were applicate for the experimental group and Jojoba oil inhalation and spa therapy was given for the control group. During the 2 weeks, the participants were treated about inhalation and spa therapy twice a week. The treatment sequence is spa therapy after inhalation therapy. Result : The improvement of stress was evaluated by POMS, HRV(Heart Rate Variability), EEG(Electroencephalography), PSQI(Pittsburgh Sleep Quality Index), salivary cortisol. After treatment, POMS was significantly decreased between the experimental group and the control group. In other measurement(HRV, EEG, PSQI, salivary cortisol) except POMS, there were not significant. Overall, however, they showed a tendency to alleviate stress in the experimental group. Conclusions : We suggest that inhalation therapy using Zizyphus jujuba var. spinosa blended oil and spa therapy might be effective on stress.

Purpose: This study identifies research trends and provides fundamental data related to curative power of aromatherapy to relieve pain in Korea. Methods: The study analyzed 44 experimental studies on humans that were published in Korea before the end of December, 2009. The key words used for searching were: aroma, aromatherapy, hyang-yobeob, hyanggi-yobeob, hyanggichilyo, aromatherapy and pain, headache, scapulodynia, omodynia, feeling uncomfortable in the perineal region, sense of pain, labor pains, arm pain, menstrual pain, aches, and dysmenorrheal. Those words were found on websites, including those for Korea Education & Research Information Service, the National Assembly Library, KISS, KoreaMed, and NDSL. Collected data were analyzed using descriptive statistics. Results: The results showed that most of essential oils to relieve pain is composed of three to four kinds of oils, including Lavender, Roman chamomile, Rosemary, and Clarysage. Aromatherapy is applied usually by means of massage (50%), inhalation (13.6%), or a combination of the above two (13.6%). Measuring instruments as a dependent variable include VAS, questionnaire, GRS, blood pressure, pulse, and Algometer. Aromatherapy plays an important role in soothing headaches and arthralgia. However, when it comes to labor and menstrual pain, it doesn't seem to be effective. Conclusion: The study found that different kinds of oil, frequencies, and periods of time are used for the same symptoms. Further research should employ standardized oil blending, application, duration, and measuring instruments, and more systematically analyze the effects of aromatherapy to establish the effects on relieving pain.

The purpose of this study was to examine the effect of aroma therapy on anxiety and pain before and after tooth extraction. The subjects in this study were 60 patients who felt severe anxiety and pain due to tooth extraction. The experiment was conducted from January through March, 2004, by organizing an experimental group and a control group with 30 patients each. The experimental group was asked to keep wearing lavender-containing necklaces from two days before tooth extraction to inhale lavender, and no such an action was taken to the control group. The collected data were analyzed with SPSS 10.0 program to obtain statistical data. and ${\times}2$ test and t-test were implemented. The findings of this study were as follows: 1. Regarding whether or not the experimental and control groups were homogeneous, men outnumbered women, and the largest number of the patients were in their 30s. Those who were married were more than the others who were unmarried in number, and those who lived with their spouses under the same roof together outnumbered the others who didn't, as the rate of the former stood at 65 percent in the experimental group and 86.4 percent in the control group. They expressed high satisfaction at their spouses, since 45 percent of the experimental group and 31 percent of the control group did it, but the difference between them and those who were unsatisfied was insignificant (pE0.347). By occupation, the largest number of people in the experimental group, which numbered 16.7 percent, were self-employed, and lots of patients in the control group were government workers. As for blood type, type A was most prevailing, which recorded 43.3 percent. By religion, 43 percent of the experimental group had no religion, whereas 36.7 percent of the control group were Christian. The most common monthly income ranged from 2 million to 2.5 million won. 2. There was little disparity in past pain experience between the two groups before aroma therapy was applied. The experimental group underwent more pain (6.15) than the control group (5.78), but the difference wasn't significant. The experimental group (90%) experienced more anxiety and fear than the control group(83%), but the difference was insignificant. This fact showed that there was little gap between the two groups in anxiety and fear caused by tooth extraction. Contrary to earlier expectation that pre-anxiety might not be the same. little significant difference was found. 3. After aroma therapy was applied, 50 percent of the experimental group and 23.3 percent of the control group suffered significantly less anxiety and fear about tooth extraction(${\times}2$=4.59, pE.05). And the experimental group exposed to aroma therapy was less nervous(3.0) than the control group(4.39), and the gap between the two was significant (t=13.37, pE.001). Therefore, aroma therapy had a good effect on alleviating their anxiety. During tooth extraction. 73.3 percent of the experimental group and 93.3 percent of the control group felt pain. The former group suffered Significantly less pain(${\times}2$=4.32, PE.05). Concerning the extent of pain, the experimental group(2.53) found it less painful to have their teeth extracted than the control group(5.50), and the gap between the two was significant(t=5.89, PE.05). 4. As to the effect of aroma therapy on alleviating anxiety or fear, the experimental group(33.3%) felt that aroma therapy let them more relieved. Every member of that group was willing to use aroma therapy again in the future, and 86.7 percent of that group perceived that aroma therapy made a difference to dental treatment. The experimental group responded to aroma therapy favorably, as every member of it had an intention to advise others to use that therapy.
