PURPOSE: This study was to examine the effects of aroma hand massage on pruritus, fatigue and stress of the patients undergoing hemodialysis. METHODS: This study was a nonequivalent control group pretest-posttest design. Study sample was conveniently recruited from two hospitals(28 for experimental and 30 for control group). The experimental group went through aroma hand massage on hand without AVF for 5 min for 12 times mixed with Lavender, Chamomile and Geranium oils in the ratio of 4 : 4 : 2, which was diluted 3% with sweet almond crrier oil 100 ml. The collected data were analyzed using SPSS/WIN 12.0. RESULTS: The 1st hypothesis, 'Experimental group who has received aroma hand massage will have lower rate of pruritus than the control group' was accepted(t = -5.084, p = .001). The 2nd hypothesis, 'Experimental group who has received aroma hand massage will have lower rate of fatigue than the control group' was accepted(t = -2.557, p = .015). The 3rd hypothesis, 'Experimental group who has received aroma hand massage will have lower rate of stress than the control group' was accepted(t = -5.537, p = .001). CONCLUSION: The aroma hand massage has shown to be an effective nursing intervention to reduce the pruritus, fatigue and stress among patients undergoing hemodialysis. Therefore, the massage is needed to continuously be applied to hemodialysis patients to improve their quality of life.

Necrotic enteritis (NE) caused by Clostridium (C.) perfringens commonly occurs in domestic broiler farms since antibiotic supplementation in poultry feed has been banned. We evaluated the antibacterial activities of medicinal plant extracts against C. perfringens isolates to select alternative compounds for preventing NE. We compared antibacterial activities using two methods and evaluated susceptibilities of the isolates based on minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Two (Fraxinus rhynchophylla Hance [FRH] and Geranium koreanum Kom. [GKK]) of the 30 plant extracts had potent antibacterial activities against C. perfringens ATCC 13124 in two assays. The MIC values for FRH and GKK against 20 C. perfringens isolates were 128~256 microg/mL and 32~128 microg/mL, respectively. The geometric MIC mean values for the two extracts were 147.2 microg/mL and 68.8 microg/mL, respectively. The MBCs for the two extracts against the same strains were 1,024~2,048 microg/mL and 256~1,024 microg/mL, respectively. The geometric mean MIC and MBC for GKK were about two-fold lower than those of FRH. The modified spot-on-lawn assay may be useful for measuring primary antibacterial potential. FRH and GKK are expected to be used as feed additives to prevent or treat NE in veterinary practice.

9.Effects of 10% Lidocaine Spray and Aroma Hand Massage on Pain, Anxiety, Blood Pressure, and Pulse During Arteriovenous Fistula Needling in Hemodialysis Patients.
Korean Journal of Rehabilitation Nursing 2016;19(1):1-11
PURPOSE: To determine the effects of 10% lidocaine spray and aroma hand massage on pain, anxiety, blood pressure, and pulse during arteriovenous (AV) fistula needling in hemodialysis (HD) patients. METHODS: This study used a quasi-experimental design. Forty HD patients were assigned to either 10% lidocaine spray group (n=21) or aroma massage group (n=19). 10% lidocaine was sprayed 3 times around AV fistula 10 minutes before. Aroma hand massage was performed for 5 minutes with fluids containing 2% of lavender, peppermint, and geranium concentrate mixture. Pain, anxiety, blood pressure, and pulse were measured during AV fistula needling without any intervention on the first week and during interventions on the second week. Data were analyzed with χ² test, Fisher's exact test, t-test, paired t-test and MANCOVA. RESULTS: Pain and anxiety were significantly decreased in both the lidocaine spray group and aroma massage group. Aroma hand massage was more effective to reduce pulse during AV fistula needling. CONCLUSION: The results suggest that 10% lidocaine spray and aroma hand massage may be effective to reduce pain, anxiety, and pulse during AV fistula needling in HD patients.

OBJECTIVES: The aim of the present systematic review and meta-analysis is the exploration of the potential evidence of the effectiveness of aromatherapy products on the sexual function of menopausal women. METHODS: From inception to December 2017, the search process was performed using the MEDLINE and Scopus databases and the Cochrane Library regarding the trials on the effectiveness of herbal-medicine aromatherapy on the sexual function of menopausal women. RESULTS: Three of the trials comprise suitable data for inclusion in the meta-analysis. According to the meta-analysis, it is possible to improve the standardized mean difference (SMD) of the sexual desire up to 0.56 in the aromatherapy group compared with the control group (SMD = 0.56; P < 0.001; heterogeneity; I² = 42%; P = 0.141). According to one of the trials, the serum-estrogen level of two different doses did not change in the neroli oil inhalation group compared with the almond-oil group. CONCLUSIONS: Both aromatherapy with neroli oil or lavender (monopreparation) and combined-oil aromatherapy with lavender, fennel, geranium, and rose significantly improved human sexual function; however, a significant change of the serum-estrogen level was not detected. The findings of the present review should be presented cautiously because of the corresponding limitations such as the lack of a standardized tool, the lack of intention-to-treat reporting, the low study amount, and the short-term follow-up.
