The Effect of Aromatherapy with Lavender Essential Oil on the Sleep and Fatigue Level of Patients with Multiple Sclerosis in Turkey: A Randomized Controlled Trial.

BACKGROUND: Fatigue is a common problem in patients with multiple sclerosis (MS) and is one of the most serious symptoms of the disease. Although many factors play a role in the etiology of fatigue in patients with MS, it has been reported that fatigue is caused by irregular or disrupted sleep patterns. AIM: The purpose of the study was to examine the effects of lavender oil aromatherapy on the sleep and fatigue of MS patients. METHODS: The study was designed as a randomized controlled trial and was conducted in Turkey. The data of the study were collected using the Patient Description Form, Fatigue Severity Scale, and Pittsburgh Sleep Quality Index. RESULTS: The mean FSS score in the experimental group was 6.86 ± 0.94 before the procedure and 3.42 ± 0.85 after the procedure, the mean PSQI score was 9.45 ± 1.23 before the procedure and 6.68 ± 2.87 after the procedure, and the difference in the mean scores between the two groups was found to be statistically significant (P < 0.001). CONCLUSION: The results showed that aromatherapy with lavender essential oil has significant impacts on fatigue and sleep in MS patients. Lavender essential oil aromatherapy can be used by nurses as an independent nursing practice. It is an inexpensive, noninvasive, and reliable technique to manage fatigue in individuals with MS.

Scenting serenity: influence of essential-oil vaporization on dental anxiety - a cluster-randomized, controlled, single-blinded study (AROMA_dent).

Dental fear and anxiety (DFA) is known as an immense challenge in oral healthcare, which can result in compromised oral health, pain, and uncomfortable treatment. The objective of this study was to analyze the effect of essential-oil vaporization on acute anxiety of patients in dental practices. Four dental practices used five weekly cycles of vaporization with each scent: Orange (Citrus sinensis), Swiss Pine (Pinus cembra), Good Mood (blended essential oils: Citrus sinensis, Citrus aurantifolia, Citrus limon, Osmanthus fragrance (5%)), Forest Walk (blended essential oils: Abies grandis, Pinus cembra, Myrtus communis c. t. 1,8-cineol, Abies alba, Citrus paradisi, Abies sibirica, Pseudotsuga menziesii, Vetiveria zizanoides), and water. Acute anxiety was the primary outcome (state-trait-anxiety inventory (STAI-S)). Secondary outcomes were trait anxiety (STAI-T), dental anxiety (Kleinknecht dental fear survey), and pain perception in treatment (numeric rating scale). Across all patients (n = 486), STAI-S was slightly higher in the control group (40.7 ± 11.6) than in the intervention groups (38.4 ± 10.5). Post-hoc analyses revealed that the effect is only robust for the subgroup of female patients (n = 296, p = 0.044). We also conducted a post-hoc additional analysis on a subpopulation with an increased level of STAI-T ≥ 42 (n = 131 patients). For this group the difference in acute anxiety between the control group (51.1 ± 11.9, n = 30) vs. the intervention groups (46.8 ± 9.6, n = 118) was significant (T = 4.39, p = 0.0379). The results of the study indicate a promising potential of essential-oil vaporization to alleviate dental anxiety, particularly in the subgroups of patients with a high level of trait anxiety, and particularly in female patients. The calming effects of the essential-oil vaporization were also highlighted by the anecdotical statements of the dental-practice staff. The anxiety-reducing role of essential-oil vaporization alone and as one part of combined techniques to counter DFA should be further explored using multi-perspective methodological approaches in research.

Effects of Aromatherapy on Physical and Mental Health of Cancer Patients Undergoing Radiotherapy and/or Chemotherapy: A Meta-Analysis.

BACKGROUP: Currently, aromatherapy is being increasingly utilized in clinical practice, particularly in managing the side effects associated with radiotherapy and chemoradiotherapy. However, it remains to be established whether aromatherapy can effectively alleviate these symptoms. OBJECTIVE: To investigate the effects of aromatherapy on the physical and mental health of patients with cancer undergoing radiotherapy and chemotherapy. METHODS: Seven databases were researched from inception until September 29, 2023, including PubMed, Scopus, and Web of Science, Chinese National Knowledge Infrastructure, Wanfang database, China Biology Medicine disc and VIP Chinese Medical Journal Database. Review Manager version 5.3 was utilized for data analysis. The Cochrane Risk of Bias tool RoB2 was employed to evaluate the quality of the literature included in the study. Evidence quality rating was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach through the GRADEpro GDT online tool. RESULTS: Nineteen studies involving 1,541 patients were included. Aromatherapy can alleviate nausea [relative risk (RR)=0.64, 95% confidence interval (CI): 0.53 to 0.78, P<0.05, I2=46%; standardized mean difference (SMD)=-0.86, 95% CI: -1.21 to -0.51, P<0.05, I2=64%] and vomiting (RR=0.54, 95% CI: 0.42 to 0.69, P<0.05, I2=35%; SMD=-1.28, 95% CI: -1.52 to -1.03, P<0.05, I2=92%), improve sleep disorders [mean difference (MD)=-3.39, 95% CI: -3.95 to -2.84, P<0.05, I2=0%], relieve pain (SMD=-1.58, 95% CI: -1.96 to -1.21, P<0.05, I2=0%), mitigate fatigue (SMD=-1.28, 95% CI: -2.44 to -0.11, P<0.05, I2=93%) and enhance quality of life (SMD=0.50, 95% CI: 0.22 to 0.79, P<0.05, I2=0%) in cancer patients after radiotherapy and chemotherapy, but it may not have a significant effect on anxiety. The risk of bias was high in the included studies using the Cochrane Risk of Bias tool RoB2, and no studies were considered to be of high grade according to the GRADE system. CONCLUSIONS: Aromatherapy is an efficacious, safe and economic adjunctive therapy for cancer patients, which can mend the physical symptoms and mental health of cancer patients. However, more high-quality studies are needed to verify it. (PROSPERO registration No. CRD42023390171).

Effect of aromatherapy with peppermint essential oil on the gag reflex: a randomized, placebo-controlled, single-blind, crossover study.

BACKGROUND: Sensitive gag reflexes prevent dental patients from receiving appropriate treatment. Aromatherapy helps patients relax during dental procedures. However, the effect of aromatherapy on the gag reflex caused by the stimulation of the oral cavity is unknown. This study aimed to evaluate whether aromatherapy reduces gag reflexes during oral stimulation. METHODS: In this randomized, placebo-controlled, single-blind, crossover study, the gag reflexes of 24 healthy individuals (12 females and 12 males; mean age: 34.3 ± 9.5 years) were quantified. A standard saliva ejector was slowly guided down the participant's throat to determine the maximum tolerance of the gag reflex, and the insertion distance was measured to quantify the gag reflex. All individuals participated in an aromatherapy session with peppermint essential oil and a placebo session with distilled water. The gag reflex was quantified before (baseline) and after each session. Another measurement was performed using nitrous oxide/oxygen inhalation as a positive control. RESULTS: Gag reflex values significantly increased after aromatherapy with both peppermint essential oil and placebo compared to baseline values (paired t-test, P < 0.001 and P = 0.014, respectively). The gag reflex value also increased significantly during nitrous oxide/oxygen inhalation (paired t-test, P < 0.001). There was no significant difference in the increase rate of gag reflex values between the positive control and aromatherapy interventions, but it was significantly lower after the placebo intervention (repeated measures analysis of variance, P = 0.003; post-hoc test, P = 0.83 and P = 0.02). CONCLUSION: Aromatherapy with peppermint essential oil has the potential for reducing gag reflex during dental procedures. TRIAL REGISTRATION: The study was registered in the University hospital Medical Information Network Clinical Trials Registry under the code UMIN000050616 (approved 17/03/2023).

Effects of Orange Oil Aromatherapy on Pain and Anxiety During Invasive Interventions in Patients With Hematopoietic Stem Cell Transplants.

Invasive interventions, such as peripheral intravenous cannula, port needle placement, and blood collection, are often required for both inpatient and outpatient follow-up patients with hematological malignancies and hematopoietic stem cell transplants. This prospective, randomized controlled experimental study assessed the effect of orange oil inhalation used in aromatherapy on pain and anxiety levels in invasive interventions with hematological malignancies and hematopoietic stem cell transplants. It was conducted prospectively with 80 patients with hematological malignancies who were treated in the adult bone marrow transplant unit and adult hematology service of a private hospital between May 2021 and April 2022. The orange oil inhalation used in aromatherapy was applied to patients in the intervention group. The Visual Analog Scale (VAS) and State-Trait Anxiety Inventory (STAI) were used for data collection. Regarding the personal characteristics of the patients, 42.5% were ≥61 years old, 60% were men, and 85% were married. VAS pain scores of the intervention group were statistically lower than those of the control group (P < .001). However, there was no statistically significant difference in the STAI scores of groups (P >.05). The study results show that orange oil inhalation has been determined to reduce pain during invasive interventions.

Effects of aromatherapy with Matricaria chamomile essential oil on anxiety and hemodynamic indices in patients with acute coronary syndrome, 2021: a randomized controlled trial.

BACKGROUND: Patients with Acute Coronary Syndrome (ACS) experience high levels of anxiety that may cause instability of hemodynamic indices, increased risk of ischemia, myocardial infarction and poor quality of life. Aromatherapy can affect patients' anxiety levels and improve hemodynamic indices. This study aimed to evaluate the efficacy of aromatherapy on anxiety and hemodynamic indices in ACS patients. METHODS: This study was a double-blind, randomized clinical trial conducted on 154 ACS patients. The participants were classified into two equal groups of intervention and placebo through the block randomization method. The data collection tools consisted of demographic information, a shortened 6-item version of the Spielberger questionnaire and a form of hemodynamic indices. For two consecutive nights, the intervention group inhaled 7 drops of the chamomile essential oil (%10) and the placebo group inhaled 7 drops of the sesame oil poured on a sterile cotton ball. The hemodynamic indices were collected half an hour before, one and four hours after the intervention until the next morning. The Spielberger questionnaire was completed once before the intervention and once after the end of the intervention, by the researcher through an interview. The number of heart rate (HR) was counted for a full minute. Also, the blood pressure (BP) of all the samples was measured by the researcher. Data analysis was done using Chi-square, paired t-test, and analysis of variance (ANOVA) in SPSS22. RESULTS: The mean and standard deviation of the age of patients were 58/2 ± 11.6 and 59.7% of them were female. The results of ANOVA showed a significantly lower anxiety score as well as systolic blood pressure (SBP), diastolic blood pressure (DBP) and HR in the intervention group compared to those of the placebo group (P < 0.001). The decrease in anxiety score after the intervention, in the intervention and placebo groups was (5.2 ± 1.9) and (1 ± 1. 18) respectively. In the intervention group, the SBP and DBP after the intervention, was significant (P < 0.05). Also, the HR was significant (P < 0.001) after the intervention. CONCLUSIONS: Aromatherapy could reduce anxiety and improve hemodynamic indices in ACS patients. TRIAL REGISTRATION: IRCT20080825001083N11.

The effect of rose oil aromatherapy and hand-holding on pain due to peripheral intravenous catheter insertion.

INTRODUCTION: The study aimed to evaluate the effectiveness of rose oil (Rosa Damascene Mill.) aromatherapy and hand-holding in reducing pain associated with peripheral intravenous catheter insertion. METHODS: A comparative mixed-method design. A total of 126 patients were included in the study. For the study's quantitative data, sociodemographic characteristics of the patients and the Patient Interview Form for the qualitative data of the Numeric Rating Scale were used. In all patients included in the study, PIVC insertion was performed a single time by the same nurse using a standard procedure. Chi-square and Bonferroni tests were used for comparative statistics. RESULTS: No statistically significant difference between the groups regarding age, gender, marital status, BMI, and education level (p>0.05). Pain scores: it was 2.40±1.78 in the rose oil group, 3.53±1.98 in the hand-holding group, and 4.88±1.56 in the control group. The difference between the groups regarding pain scores is statistically significant (p=0.001). CONCLUSIONS: The study determined that rose oil aromatherapy and hand-holding interventions reduce pain during PIVC. However, rose oil aromatherapy was more effective on pain than the hand-holding intervention. (Clinical Trial ID: NCT05425849).

Nonpharmacological Nursing Interventions in Postoperative Nausea and Vomiting: A Systematic Review.

PURPOSE: This study aims to assess the impact of nonpharmacological nursing interventions on postoperative nausea and vomiting (PONV). DESIGN: This is a systematic review. METHODS: MEDLINE, Web of Science, ScienceDirect, Tübitak-ULAKBIM, and TRDizin databases were searched for the following search terms, including "Postoperative Nausea and Vomiting," "Nurse," "Nursing," and "Nonpharmacological Interventions" to identify nonpharmacological nursing interventions for PONV. A systematic review of English and Turkish articles published in the period between January 1, 2012 and June 1, 2023 was conducted. The PICOT-SD method was used to determine the compatibility of the pieces with the eligibility criteria. FINDINGS: Fifty-eight of 3,874 articles obtained from databases fulfilled the eligibility criteria. This study demonstrated that acupuncture, aromatherapy, the oral intake of ginger, listening to music, education, and visits to patients decreased the incidence of nausea and vomiting and increased the quality of life. Additionally, it was found that patients' quality of life tended to improve along with reductions in postoperative complications. CONCLUSIONS: The results of this study support previous findings in the literature and demonstrate that nonpharmacological nursing interventions help reduce and prevent PONV. Based on our results, we suggest that nonpharmacological nursing interventions can be employed for the management of PONV in patients undergoing surgery.

The effects of aromatherapy with thyme oil on disease symptoms, vital findings, and hemodynamic parameters in COVID-19 patients.

OBJECTIVE: To determine the effect of aromatherapy with thyme oil on disease symptoms, vital signs, and hemodynamic parameters in COVID-19 patients. METHODS: We conducted the randomized controlled trial with 140 (experimental group=70, control group=70) COVID-19 patients. Patients admitted to the COVID-19 service of the Batman Training and Research Hospital were included in the sample between 31.01 - 31.08 2022. Patients in the experimental group inhaled thyme oil 3 times a day during 5 days. At the end of day 5, symptoms and hemodynamic parameters were measured as posttest. Vital signs were measured 3 times a day during 5 days. The control group only received routine treatment. RESULTS: Thyme oil was found to be effective in relieving symptoms of shortness of breath, dizziness, secretion, diarrhea, weakness, loss of appetite, cough, headache and muscle joint pain. Although there was improvement in the symptoms of nausea-vomiting, runny nose and loss of taste-smell, the effect was not statistically significant. Thyme oil significantly decreased body temperature, pulse rate and respiratory rate (p<0.05), increased SPO 2 (p<0.05), and did not affect systolic and diastolic blood pressure (p>0.05). It had a significant effect on the regulation of pH, decreased CO2 and increased O2 significantly (p<0.05). CONCLUSION: Thyme oil aromatherapy was effective in reducing symptoms, regulating vital signs and hemodynamic parameters. Accordingly, thyme oil is recommended as non-pharmacological treatment method in COVID-19 patients.

The Effect of Reiki and Aromatherapy on Vital Signs, Oxygen Saturation, and Anxiety Level in Patients Undergoing Upper Gastrointestinal Endoscopy: A Randomized Controlled Study.

This randomized controlled study aimed to determine the effect of Reiki and aromatherapy on vital signs, oxygen saturation, and anxiety level in patients undergoing upper gastrointestinal endoscopy. The sample consisted of 100 patients divided into Reiki (n = 34), aromatherapy (n = 33), and control (n = 33) groups. Data were collected 3 times (before, during, and after the procedure) using a descriptive characteristics questionnaire, a follow-up form, and the State Anxiety Subscale. The Reiki group had a mean State Anxiety Subscale score of 53.59 ± 2.98 and 43.94 ± 4.31 before and after the procedure, respectively. The aromatherapy group had a mean State Anxiety Subscale score of 54.03 ± 4.03 and 43.85 ± 3.91 before and after the procedure, respectively. The control group had a mean State Anxiety Subscale score of 38.79 ± 4.68 and 53.30 ± 7.26 before and after the procedure, respectively (P < .05). The results showed that the Reiki and aromatherapy groups had significantly lower State Anxiety Subscale scores than the control group after the procedure, indicating that Reiki and aromatherapy help reduce anxiety levels. There was a significant difference in the mean respiratory rates and oxygen saturation levels between the groups (P < .05). In conclusion, patients who do Reiki or undergo aromatherapy are less likely to experience anxiety before upper gastrointestinal endoscopy.

Effect of peppermint-lemon aromatherapy on nausea-vomiting and quality of life in pediatric patients with leukemia: A randomized controlled trial.

BACKGROUND: Nausea and vomiting, frequently induced by chemotherapy, can delay treatment protocols and the healing process. PURPOSE: The aim of this study is to determine how aromatherapy inhalation with peppermint and lemon using a diffuser affects nausea-vomiting management and quality of life in 2-12-year-old children undergoing chemotherapy. DESIGN AND METHODS: The study utilized a pretest-posttest control group experimental design with randomized groups. A total of 90 children who met the inclusion criteria were included in the study. The experimental group received Mentha Piperita and Citrus Lemon essential oils through a diffuser, while the placebo group received water through a diffuser. The control group did not receive any intervention. RESULTS: Pulse and respiratory rates of children treated with aromatherapy were found to be significantly lower than the other groups. After aromatherapy application, quality of life of the children in the experimental group was significantly higher than the other groups. The change in the Index of Nausea, Vomiting, and Retching scores of the experimental group on the 4th chemotherapy cycle compared to the 1st chemotherapy cycle was significantly higher than the change in the other groups. CONCLUSIONS: Consequently, it was determined that inhalation aromatherapy with peppermint-lemon was effective in the management of chemotherapy-induced nausea-vomiting symptoms and quality of life compared to the placebo and control groups. PRACTICE IMPLICATIONS: Inhalation aromatherapy with mint-lemon can be used as an alternative method to improve the quality of life in children with leukemia who suffer from chemotherapy-induced nausea and vomiting.

The effect of ylang oil and lemon oil inhalation on labor pain and anxiety pregnant women: A randomized controlled trial.

BACKGROUND: and purpose: To date, there has been very limited experimental research on the impact of ylang ylang oil and lemon oil inhalation labor pain. This study was conducted to investigate the effects of aromatherapy, one of the non-pharmacological pain methods, on anxiety and labor pain in the active phase in primiparous pregnant women. METHODS: A randomized controlled trial design was used in the study, which was conducted with 45 primiparous pregnant women. Volunteers were randomized into the lemon oil group (n = 15), ylang-ylang oil group (n = 15), and control group (n = 15) by using the sealed envelope method. The visual analog scale (VAS) and the state anxiety inventory were applied to the intervention and control groups before the application. After the application, the VAS and the state anxiety inventory were applied at 5-7 cm dilatation and the VAS was applied alone at 8-10 cm dilatation. The trait anxiety inventory was applied to the volunteers after delivery. RESULTS: The mean pain scores at 5-7 cm dilatation in the intervention groups (lemon oil 6.90, ylang ylang oil, 7.30) were significantly lower than in the control group (9.20) (p = 0.005). There was no significant difference between the groups in terms of their mean pre-intervention and 5-7-cm-dilatation anxiety scores (p = 0.750; p = 0.663), mean trait anxiety scores (p = 0.094), and mean first-and fifth-minute Apgar scores (p = 0.051; p = 0.051). CONCLUSION: It was found that aromatherapy applied by inhalation at labor reduced the perception of labor pain but had no effect on anxiety.

The immediate effects of lavender-based essential oil inhalation on subsequent polysomnography in people with poor sleep quality.

BACKGROUND: Although aromatherapy is considered an adjuvant therapy to promote sleep quality, few objective sleep testing instruments can confirm the effects of aromatherapy on sleep physiology. The purpose of this study was to confirm and compare the immediate effects of a single lavender essential oil (SLEO) group to a complex lavender essential oil (CLEO) group by objective polysomnography (PSG) recordings. METHODS: Participants were randomly divided into the SLEO group and CLEO group in this single-blind trial to explore the sleep effect of essential oil aroma. All the participants completed the sleep-related questionnaires and underwent two consecutive nights of PSG recordings, who had one night without aromatherapy and one night with one of the two aromas randomly assigned to them. RESULTS: Total of 53 participants were recruited for this study, 25 participants were in the SLEO group, and 28 were in the CLEO group. Baseline characteristics and sleep-related questionnaires were similar in both groups. Both SLEO and CLEO extended the total sleep time (TST) (Δ = 43.42 and 23.75 minutes, respectively) and sleep period time (SPT) (Δ = 38.86 and 24.07 minutes, respectively). The SLEO group further improved sleep efficiency and increased the amounts of non-rapid eye movement (NREM) and rapid eye movement (REM) sleep and decreased spontaneous arousals. However, there was no significant difference in PSG parameters between the SLEO and CLEO groups. CONCLUSION: Both SLEO and CLEO extended TST and SPT, with no significant differences between these two groups. These results warrant practical applications and merit future studies (Clinical trial registration: ClinicalTrials.gov : NCT03933553).

Effects of Aromatherapy on Cancer Patients' Sleep and Fatigue: A Systematic Review and Meta-Analysis.

Objective: This study aims at investigating the effectiveness of aromatherapy in enhancing sleep quality and reducing fatigue among cancer patients based on randomized controlled trials (RCTs) with a high level of evidence. Design: A systematic review and meta-analysis. Methods: Two reviewers screened and reviewed the full texts of search results obtained from six English databases and four Korean databases, and they extracted data from the selected studies independently. Risk of bias (RoB) was assessed using the revised Cochrane RoB tool for randomized trials. The review protocol was registered with the International Prospective Register of Systematic Reviews (CRD42021277515). Results: Eleven RCTs were included in this study. Aromatherapy significantly improved sleep quality among cancer patients compared with those in the control groups (routine care, no intervention, and placebo) (standardized mean difference [SMD] = -0.92, 95% confidence interval [CI]: -1.39 to -0.46; p < 0.001, I2 = 89%). However, aromatherapy did not significantly reduce fatigue among such patients (SMD = -0.40, 95% CI: -0.81 to 0.01). The results of the meta-regression confirmed that increased intervention sessions resulted in the enhanced effectiveness of aromatherapy in improving sleep quality among cancer patients (Z = -3.86, p < 0.001). Conclusion: This study showed that aromatherapy significantly improves sleep quality among cancer patients. However, aromatherapy does not significantly reduce fatigue among cancer patients. It is possible that the statistical power of the meta-analysis was weak due to the small number of included studies. Therefore, in future studies, the effects of aromatherapy on fatigue among cancer patients should be assessed further using a larger number of included studies. Further, the effects of aromatherapy should be evaluated with a focus on specific subsets of patients, such as specific cancer diagnoses and specific modalities for cancer treatment.

"Like one part of a puzzle" - individualized aromatherapy for women with gynecological cancers in aftercare: results from a qualitative-focused mixed-methods study.

BACKGROUND: Gynecological cancer(s), including breast cancer patients in aftercare and survivors, need supportive strategies to cope with symptoms that are adapted to their individual needs and circumstances. Aromatherapy has potential to be such strategy, but (qualitative) empirical research taking users' own views into consideration about the potential and challenge of aromatherapy is lacking. PURPOSE: The purpose of the study is to gain insights from individualized aromatherapy as a supportive care treatment, regarding their use and evaluation by women with gynecological cancers in aftercare. METHODS: We conducted a study with a mixed-methods design, focused on qualitative research. Five essential oil products were given to 18 participants to apply individually over a 4-week period. After the intervention, qualitative semi-structured interviews were conducted. Further, we documented and assessed symptomatic burdens of the women (MYMOP2) before and after intervention quantitatively. RESULTS: Aromatherapy was customized by the participants according to their needs. It showed potential for relief of symptomatic burdens - especially nausea, peripheral neuropathy, pain, and sleep. Additionally, opportunities emerged to indirectly affect symptomatic burdens. These developed out of new coping strategies (e.g., sleep routines) or by combining with existing strategies (e.g., meditation). Furthermore, aromatherapy was successfully used to promote well-being and encourage mindfulness. CONCLUSION: Our findings demonstrated the potential of aromatherapy as a supportive treatment modality that can be used as a kind of toolbox. Challenges, such as individual odor aversions and intolerances, and limitations due to medication or illness should be considered in future aromatherapy research.

Use of Aromatherapy for Pediatric Surgical Patients.

BACKGROUND: Children having surgery experience distress from a myriad of sources. Aromatherapy may present an opportunity to promote a healing environment and decrease distress for children following surgery. AIM: Evidence regarding the use of aromatherapy with children is growing. The purpose of this project was to describe our implementation process, subsequent use of and response to aromatherapy for children undergoing surgery. METHODS: This quality improvement project and subsequent retrospective chart review included all patients with documentation of aromatherapy use over an 8-month period. Data collection included demographic data, patient diagnosis, location, information about which oils were used, for which indications, and any outcome the nurse was able to observe (e.g., improved, no change, worsening of symptoms). A nurse-led workgroup developed and implemented a process for aromatherapy in a limited scope when discomfort, nausea/vomiting, nervousness, and sleep disturbances were reported . Charts of all patients with documented aromatherapy use were reviewed for indication/reason for use, oil, and patient response. RESULTS: Results suggest a successful implementation process. Aromatherapy was used by 191 patients (aged 3-22 years). Upset stomach, discomfort, and nervousness were most frequently reported as leading to aromatherapy use. Lavender and peppermint were the most frequently used oils. Of those patients with documented responses, the majority reported improvement. CONCLUSIONS: We were able to successfully implement a new aromatherapy program as an adjunct to care in children undergoing surgery. No adverse events were reported. Documentation is crucial to evaluating any new service.

The Impact of Aromatherapy with Citrus Aurantium Essential Oil on Sleep Quality in Pregnant Women with Sleep Disorders: A Randomized Controlled Clinical Trial.

Background: Sleep disorders are so prevalent during pregnancy. The present study was conducted to investigate the impact of aromatherapy with Citrus aurantium essential oil on sleep quality in pregnant women with sleep disorders. Methods: This randomized clinical trial study was conducted on 68 pregnant women in their 28-34 weeks of pregnancy who sufferred sleep disorders and referred to Jiroft health centers in 2021 (January-June). Those meeting the inclusion criteria were divided into the intervention and placebo groups, using random sequence generated through the randomization website. They were given five drops of Citrus aurantium essential oil and the placebo twice a day, every day for one month in the form of facemasks which they inhaled through normal breathing for 20 minutes. Sleep quality was assessed before the intervention and one month after the start of the intervention. The demographic questionnaire and Pittsburgh Sleep Quality Index (PSQI) were used for collecting the data. Data analysis was performed using SPSS 24 software. The Mann-Whitney-U, Wilcoxon and fisher exact tests were carried out. P-value<0.05 was considered statistically significant. Results: Before the intervention, the mean and standard deviation scores of pregnant women's sleep quality in the intervention (9.89±3.00) and placebo (8.12±2.53) groups were not significantly different (P=0.10). One month after the intervention, the score was significantly lower in the intervention group (4.37±1.85) than the placebo group (8.48±2.62) (P<0.001). Conclusion: Based on the results of the present study, it seems that aromatherapy with Citrus aurantium essential oil enhances the sleep quality in pregnant women with sleep disorders, so it can be used to diminish sleep disorders in these women.Trial Registration Number: IRCT20200512047414N1.

Exploration of Aromatherapy in a Pediatric Outpatient Surgical Setting: A Pilot Study.

PURPOSE: To explore whether an aromatherapy product, QueaseEASE, could be used to supplement standard postoperative nursing care for children experiencing discomfort from postoperative nausea and vomiting (PONV) in a pediatric outpatient surgical setting. DESIGN: Evidence-based practice project resulting in a prospective, descriptive research design. METHODS: English-speaking pediatric outpatient surgical patients 8 to 17 years of age were evaluated for symptoms of discomfort during the postoperative phase of care, using the Baxter Animated Retching Faces (BARF) scale and offered the QueaseEASE aromatherapy product. A postoperative phone call was made the next business day to inquire about use of product at home. FINDINGS: Thirty-one patients rated their BARF scores as four or greater and were qualified to use the aromatherapy pod. Twenty-four patients (77.4%) demonstrated a positive response to the aromatherapy, as evidenced by a BARF score improvement of 2 or more points upon reassessment. Fourteen of the 27 patients (51.8%) contacted at home during the postoperative phone call stated continued use of the aromatherapy pod, and 100% of the families were satisfied with this adjunct therapy. CONCLUSIONS: Aromatherapy resulted in an improvement in self-reported nausea scores in a pediatric surgical outpatient population and was a family satisfier. Further research is recommended.

Effectiveness of aromatherapy with inhaled lavender essential oil and breathing exercises on ECT-related anxiety in depressed patients.

Background and aims Electroconvulsive therapy (ECT) is considered a safe, effective, and significant treatment in patients suffering from a major depressive disorder. Anxiety caused by this invasive treatment may impose several side effects on patients. The purpose of this study was to evaluate the effectiveness of aromatherapy with inhaled lavender essential oil and breathing exercises on ECT-related anxiety in depressed patients. Methods In this randomized controlled clinical trial, 90 depressed patients were selected and divided into three groups: aromatherapy, breathing exercise, and routine care using a random allocation method. Before undergoing ECT, the aromatherapy group was exposed to the inhaled lavender essential oil (n = 30), the breathing exercise group performed the breathing exercises (n = 30), and the routine care group received routine care (n = 30). Before (20 min) and after the intervention (30 min later), patients' anxiety was assessed using Beck Anxiety Inventory. Results After the intervention, the results revealed that anxiety score changes were statistically significant among the three groups (p < 0.001). In addition, it was found that the patients' mean anxiety scores significantly decreased in the aromatherapy and breathing exercise groups compared to with the pre-intervention scores (p < 0.001). Conclusion Aromatherapy with inhaled lavender essential oil and breathing exercises can be considered by clinical nurses as simple, applicable, and effective interventions to reduce ECT-related anxiety in depressed patients.

Essential oils as anticancer agents: Potential role in malignancies, drug delivery mechanisms, and immune system enhancement.

Cancer retains a central place in fatality rates among the wide variety of diseases known world over, and the conventional synthetic medicaments, albeit used until now, produce numerous side effects. As a result, newer, better, and safer alternatives such as natural plant products, are gravely required. Essential oils (EOs) offer a plethora of bioactivities including antibacterial, antiviral, antioxidant, and anticancer properties, therefore, the use of EOs in combination with synthetic drugs or aromatherapy continues to be popular in many settings. In view of the paramount importance of EOs and their potential bioactivities, this review summarizes the current knowledge on the interconnection between EOs and cancer treatment. In particular, the current review presents an updated summary of the chemical composition of EOs, their current applications in cancer treatments based on clinical studies, and the mechanism of action against the cancer cell lines. Similarly, an overview of using EOs in aromatherapy and enhancing immunity during cancer treatment is provided. Further, this review focuses on the recent technological advancements such as the loading of EOs using protein microspheres, ligands, or nanoemulsions/nanoencapsulation, which offer multiple benefits in cancer treatment via site-specific and target-oriented delivery of drugs. The continuing clinical studies of EOs implicate that their pharmacological applications are a rewarding research area.
