Both lavender fleur oil and unscented oil aromatherapy reduce preoperative anxiety in breast surgery patients: a randomized trial

Decreasing Preoperative Anxiety in Patients with Newly Available Multimodal Approaches-A Narrative Review

Preoperative anxiety affects approximately 80% of adult patients; thus, identifying patients with excessive anxiety and implementing appropriate interventions can significantly reduce the risk of deterioration during the perioperative period. This narrative review presents current knowledge about pharmacological and nonpharmacological methods for reducing preoperative anxiety. Commonly used pharmacological options include benzodiazepines, ketamine, or fentanyl. Antidepressants have also been shown to be effective in alleviating symptoms, but they typically require four weeks to take effect. Establishment of supportive relationships with medical staff to help patients express their feelings have been shown to have a positive impact on anxiety reduction. Other nonpharmacological methods include the provision of information through informed consent forms, video materials, virtual reality, or the use of psychotherapeutic interventions such as breathing techniques, music therapy, or cognitive-behavioural therapy. Some studies suggest that essential oils may have a role in reducing perioperative anxiety. Nonpharmacological interventions can be used in patients of different ages. An increasing number of researchers advocate for a holistic approach that integrates less invasive and cost-effective interventions with conventional medicine. While various interventions have been proposed to manage preoperative anxiety, more research is needed to establish the most effective and feasible interventions for different patient populations.

The Effect of Nonpharmacological Methods on Preoperative Anxiety in Breast Surgery Patients: A Meta-analysis

PURPOSE

To investigate the effect of nonpharmacological methods on anxiety before breast surgery, using the meta-analysis method.

DESIGN

A meta-analysis.

METHODS

Nine electronic databases were searched to identify studies published up to October 2023. The study was carried out in accordance with Preferred Reporting Items for Systematic Review and Meta-analyses 2020 and Cochrane 2021 recommendations. The Risk of Bias 2 tool was used to assess the risk of bias. Heterogeneity and publication bias were also assessed.

FINDINGS

A search of 9 electronic databases identified 280 records. Six studies that met the inclusion criteria were eligible for meta-analysis. All the trials explained how the randomization was done. The studies selected were published between 2016 and 2022. A total of 519 female patients were included in the selected trials, 303 in the intervention group and 216 in the control group. The studies included aromatherapy, music, electro-acupuncture, and Yokukansan Kampo medicine practices. A meta-analysis was performed with anxiety levels measured immediately before surgery. In addition, a subgroup analysis was performed with trials that used anxiety-specific scales before surgery and trials that used aromatherapy.

CONCLUSIONS

The results of this meta-analysis indicated a moderate efficacy of nonpharmacological approaches, whereas aromatherapy showed a relatively lower efficacy in reducing preoperative anxiety in breast surgery patients.

Perioperative Anxiety: Current Status and Future Perspectives

Perioperative anxiety is a multifaceted phenomenon that significantly impacts patients undergoing surgical procedures. Despite advancements in surgical techniques and anesthetic management, the psychological burden associated with anesthesia and surgery remains a significant challenge for healthcare providers. Up to 30% of patients suffer from anesthesia-related preoperative anxiety, irrespective of whether the procedure is elective or emergent. Notably, anxiety can adversely affect patient outcomes, including pain management, patient safety, overall quality of care, and patient satisfaction. Addressing perioperative anxiety requires a comprehensive understanding of its causes, assessment tools, and management strategies to ensure optimal perioperative care. This review examines the historical context, incidence, causes, pathophysiology, assessment tools, and current evidence regarding management strategies for anesthesia-related anxiety, and provides an outlook on future directions for research and everyday practice.

Effect of Citrus aurantium and chamomile aromas on anxiety and vital signs in cardiac care unit patients: A randomized clinical trial

Background and Aim

Complementary therapies, such as aromatherapy, were used to manage acute and chronic symptoms of diseases. Anxiety symptoms and deviations in vital signs are frequently manifest in patients admitted to the cardiac care unit (CCU). This study aimed to evaluate the impact of citrus aurantium and chamomile aromas on anxiety levels and vital signs of patients hospitalized in CCU.

Methods

In this clinical research trial (CRT), a total of 76 hospitalized patients in the CCU were randomly assigned to two groups. The intervention group received aromatherapy using a blend of chamomile and citrus aurantium essences at a ratio of 2:0.5 on an eye pad. They inhaled the aromas from a distance of 10 cm for three nights. Vital signs were recorded every 6 h. Spielberger's anxiety questionnaire was administered before and after the intervention. Data were analyzed using independent t-tests, paired t-tests, Chi-square tests, Fisher's exact tests, and the generalized estimating equation (GEE) approach.

Results

Before the aromatherapy, the mean (SD) scores of state and trait anxiety in the intervention group were 57.9 (11.4) and 50 (12.5) respectively, after the intervention, these scores decreased to 35.3 (8.4) and 38.5 (8.2), and the paired t-test revealed a significant difference between them (p < 0.001). Before the intervention there was no significant difference in the mean scores of state and trait anxiety between the two groups, (p > 0.05), however following the intervention, a significant difference was observed (p < 0.001). Additionally, the intervention resulted in the recovery of patients' heart rate.

Conclusions

The results showed, application of citrus aurantium and chamomile aromas significantly lower anxiety levels and enhance the hemodynamic status of patients in the CCU. It may be suggested as a beneficial nursing intervention for these patients.

The effect of aromatherapy on patients with acute coronary syndrome: A systematic review and meta-analysis

OBJECTIVE

To systematically investigate the efficacy of aromatherapy in patients with acute coronary syndrome (ACS).

METHODS

We conducted a comprehensive search for papers published until November 2023 using the following databases: PubMed, Embase, and Cochrane Library. This study was conducted following the PRISMA and Cochrane Guidelines. The inclusion criteria were randomized controlled trials (RCTs) performed to assess the comparative effectiveness of inhalation aromatherapy versus controls in individuals diagnosed with ACS. The Jadad rating method was used to assess the quality of the included studies, and a meta-analysis was performed using the RevMan 5.4 software. Heterogeneity was quantified using the Higgins I2 (%) test.

RESULTS

A total of 12 RCTs with 476 patients with ACS were included. Aromatherapy has been shown to reduce anxiety scores significantly (standard mean difference [SMD]: -1.18, 95 % confidence interval [CI]: -1.33 to -1.03; P < 0.00001) along with reduction in systolic blood pressure (MD = -8.78, 95 % CI [-13.92, -3.65], P = 0.008); diastolic blood pressure (MD = -7.76, 95 % CI [-11.39, -4.12], P < 0.001); mean artery pressure MD = -9.68, 95 % CI [-13.93.-5.44]; P < 0.0001). However, no significant effects were reported on the heart rate (MD = -6.98, 95 % CI [-15.46, 1.50], P = 0.11) and respiratory rate (MD = -0.67, 95 % CI [-2.52, 1.19], P = 0.48). A greater frequency of aromatherapy was associated greater anxiety -1.80 incidence, with 95 % CI [-2.04, -1.56]. Citrus essential oils exhibited the strongest effect (SMD = -1.97, 95 % CI [-3.34, -0.60], P = 0.005) in reducing anxiety levels.

CONCLUSION

Aromatherapy appears to be an effective non-pharmacological intervention for reducing blood pressure and anxiety in individuals with ACS. This suggests that aromatherapy more than twice a day is effective in reducing anxiety levels. However, aromatherapy had no statistically significant impact on the heart or respiratory rates. Moreover, additional high-quality RCTs should be conducted to verify these results and explore the efficacy and mechanism of aromatherapy in patients with ACS.

The Effect of Aromatherapy on Anxiety and Pain in Patients Undergoing Oculoplastic Surgery

PURPOSE

To determine the effect of aromatherapy on postoperative anxiety and pain in patients undergoing oculoplastic surgery.

METHODS

A randomized controlled study of 60 patients who underwent monitored anesthesia care sedation for oculoplastic procedures from August 2018 to November 2020. Patients were randomized to an aromatherapy (n = 32) or placebo (n = 28) condition. Anxiety was measured with State-Trait Anxiety Inventory and visual analog scale for anxiety. Pain was measured with a visual analog scale for pain.

RESULTS

Compared with control patients, aromatherapy patients had significantly lower postoperative State-Trait Anxiety Inventory state anxiety (24.1 vs. 29.1; p = 0.05) and visual analog scale pain scores (1.9 vs. 3.2; p = 0.05). Aromatherapy patients also had shorter stays in the postanesthesia care unit than control patients (57.7 vs. 79.4 minutes; p = 0.03).

CONCLUSIONS

Patients who received aromatherapy reported lower postoperative anxiety and pain. Aromatherapy may be a useful adjuvant analgesic and/or anxiolytic for patients undergoing oculoplastic procedures with monitored anesthesia care sedation.

The effect of lavender and bergamot oil applied via inhalation on the anxiety level and sleep quality of surgical intensive care unit patients

OBJECTIVE

Due to numerous stressors in intensive care, common psychosocial problems arise in patients. Among these, decreased anxiety and sleep quality are observed. This study aims to determine the effect of lavender and bergamot oil applied by inhalation on anxiety and sleep quality in surgical intensive care unit patients.

METHODS

Fifty-four patients hospitalized in the intensive care unit of a hospital in Istanbul, Turkey, were included in this study. They were randomly divided into three groups (Lavender, Bergamot, Control). Intervention groups were exposed to 3 drops of lavender oil or bergamot oil on pillows for 20 min, which were then placed 10 cm away from the patient's head. This intervention was applied for two nights. The patients' sleep quality and anxiety level were evaluated using the "State-Trait Anxiety Inventory (STAI)" and "Richard-Campbell Sleep Scale (RCSS)." Data were analyzed using Chi-square, independent t-test, One-way ANOVA tests.

RESULTS

According to our results, anxiety scores significantly decreased in the lavender and bergamot groups. Sleep quality scores significantly increased (p = <0.001). The control group showed lower sleep quality scores.

CONCLUSION

Lavender and bergamot oil inhalation appeared effective in reducing anxiety and improving sleep quality in surgical intensive care unit patients.

Effect of Lavender Oil on Preoperative Anxiety: Systematic Review and Meta-analysis

PURPOSE

Surgical interventions are known to induce anxiety in patients due to the associated risks and potential complications. Various methods are employed to alleviate preoperative anxiety. This study aimed to investigate the impact of lavender oil application on the anxiety levels of patients scheduled for surgical procedures.

DESIGN

Systematic review and meta-analysis.

METHODS

Studies were accessed using the keywords "preoperative and lavender oil and stress" in Turkish and English between July 1 and 30, 2022, through PubMed (including MEDLINE), Cochrane, EBSCOhost, Web of Science, YÖK National Thesis Center, and Google Scholar. The standardized mean difference was calculated using random-effects models, and the Cochrane Collaboration tool was used to assess the risk of bias in each study. The study was prepared according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis checklist.

FINDINGS

Twenty studies were included in the analysis. The anxiety level of the experimental group to which lavender oil was applied before the surgical intervention was significantly lower than that of the control group (standardized mean difference:-5.40; 95% CI: -8.76 to -2.04).

CONCLUSION

Preoperative lavender oil application was found to be an effective method for relieving patients' anxiety. Lavender oil is thought to be a potential standalone treatment for preoperative anxiety.

Aromatherapy for the brain: Lavender's healing effect on epilepsy, depression, anxiety, migraine, and Alzheimer's disease: A review article

Neurological diseases affect the nervous system, including the brain, spinal cord, cranial nerves, nerve roots, autonomic nervous system, neuromuscular junctions, and muscles. Herbal medicine has long been used to cure these diseases. One of these plants is lavender, which is composed of various compounds, including terpenes, such as linalool, limonene, triterpenes, linalyl acetate, alcohols, ketones, polyphenols, coumarins, cineole, and flavonoids. In this review, the literature was searched using scientific search engines and databases (Google Scholar, Science Direct, Scopus, and PubMed) for papers published between 1982 and 2020 via keywords, including review, lavender, and neurological disorders. This plant exerts its healing effect on many diseases, such as anxiety and depression through an inhibitory effect on GABA. The anti-inflammatory effects of this plant have also been documented. It improves depression by regulating glutamate receptors and inhibiting calcium channels and serotonergic factors, such as SERT. Its antiepileptic mechanism is due to an increase in the inhibitory effect of GABA and potassium current and a decrease in sodium current. Therefore, many vegetable oils are also used in herbal medicine. In this review, the healing effect of lavender on several neurological disorders, including epilepsy, depression, anxiety, migraine, and Alzheimer's disease was investigated. All findings strongly support the traditional uses of lavender. More clinical studies are needed to investigate the effect of the plants' pharmacological active constituents on the treatment of life-threatening diseases in humans. The limitations of this study are the low quality and the limited number of clinical studies. Different administration methods of lavender are one of the limitations of this review.

Benefit of inhalation aromatherapy as a complementary treatment for stress and anxiety in a clinical setting – A systematic review

OBJECTIVE

The purpose of this systematic review is to ascertain the impact of inhalation aromatherapy on stress and anxiety in clinical settings.

METHODS

A search strategy was developed using various databases. Randomised Controlled Trials (RCTs) as well as single and double-blind pilot clinical studies (non-RCT) using inhalation aromatherapy with an essential oil blend or a single essential oil were examined. All studies included a control intervention and use of a validated measurement tool. The time period under review was years 2000-2021. Due to the high level of heterogeneity and element of bias, a narrative synthesis was conducted.

RESULTS

The search strategy initially retrieved 628 studies and through application of the selection criteria and the removal of duplicates, 76 studies were selected for review with a total of 6539 patients. In 42% of the RCTs, physiological measures including vital signs and/or salivary cortisol were used in addition to questionnaires. Over 70% of the studies reported a positive effect on anxiety levels in the aromatherapy intervention groups compared with the control. However, in many cases this is limited by the absence of safety data, imprecise reporting of plant species and dosage of essential oil.

CONCLUSION

Inhalation aromatherapy has the potential to reduce stress and anxiety with data emerging to further support this result across a wide modality of clinical treatments. However, there is a clear need for the development of standard protocols for research in this area, generating measurable results which will create the opportunity for more rigorous evidence-based outcomes.

Aromatherapy in Nursing and Midwifery Practice: A Scoping Review of Published Studies Since 2005

Aromatherapy with inhalation can effectively improve the anxiety and depression of cancer patients: A meta-analysis

PURPOSE

This meta-analysis was to critically evaluate the effects of aromatherapy on the symptoms of anxiety and depression in cancer patients.

METHODS

Eight Chinese and English databases (CNKI, Wanfang, VIP, CBM, Cochrane Library, PubMed, Embase, and PsycINFO) were systematically searched from the inception of databases to October 2021 for randomized controlled trials (RCTs). According to Cochrane Collaboration criteria, two reviewers independently assessed the risk of bias and extract data from included studies. All analyses were performed with Review Manager 5.4.

RESULTS

Eleven qualified studies were included in the meta-analysis, ten of which reported the effect of aromatherapy on anxiety in cancer patients, including 1724 patients; five of the studies reported the effect on depression, including 1039 patients. The quality of the included studies was low, and most studies compared aromatherapy to usual care. This meta-analysis indicated that aromatherapy appeared to be effective for anxiety [SMD = -0.51, 95%CI (-0.83, -0.19), P = 0.002] and depression [SMD = -0.44, 95%CI (-0.76, -0.12), P = 0.008] symptoms in cancer patients. Inhalation aromatherapy may be more effective than massage. Aromatherapy seemed to improve the anxiety symptoms in cancer patients in a short time, especially in perioperative patients, but had no effect for patients treated with radiation, chemotherapy or palliative therapy. Placebo also appeared to be effective in some studies.

CONCLUSIONS

Aromatherapy, especially inhalation aromatherapy, may help relieve symptoms of anxiety and depression in cancer patients, but more and higher-quality studies are needed. The literature does not yet support clinical implementation.

Inhalation Aromatherapy via Brain-Targeted Nasal Delivery: Natural Volatiles or Essential Oils on Mood Disorders

Mood disorders, also often referred to as affective disorders, are a group of psychiatric illnesses that severely impact mood and its related functions. The high medical expenditures have placed a significant financial burden on patients and their families. Aromatherapy is an alternative and complementary treatment that utilizes essential oils (EOs) or volatile oils (VOs) to achieve major therapeutic goals. In general, EOs are volatile chemicals that enter the body primarily through skin absorption and/or nasal inhalation. In addition, they can work through oral administration. Inhalation aromatherapy has shown unique advantages for treating mood disorders, especially depression, anxiety and mental disorders such as sleep disorder, which have been validated over the last decade through clinical and animal studies. Accumulating evidence has shown that EOs or VOs can bypass the blood-brain barrier to target brain tissue through the nasal-brain pathway. Subsequently, they act on the cerebral cortex, thalamus, and limbic system in the brain to improve symptoms of anxiety, depression and improve sleep quality. Here, we review the natural aromatic plants' volatiles or essential oils used commonly as adjuncts to manage mood disorders and illustrate the mechanisms of inhalation aromatherapy, and mainly summarized the application of transnasal inhalation aromatherapy in depression, anxiety, and sleep disorders. We conclude that aromatherapy does not cause side-effects, which is vastly different from commonly used psychotropic drugs. Inhalation aromatherapy via brain-targeted nasal delivery offers potentially efficacious treatment for mental disorders and merits further study.

Improving Breast Surgery Outcomes Through Alternative Therapy: A Systematic Review

Enhanced recovery after surgery (ERAS) protocols are the current standard of care when it comes to improving post-surgical outcomes in breast cancer patients. Compliance with all protocol items is required in order for patients to experience significant benefits. Given that the ERAS protocols involve numerous medications which each have unique side effect profiles and medication interactions, this is often difficult to accomplish. Additionally, breast cancer patients are often left with a large psychological burden, which ERAS protocols fail to address. This review aims to determine the role that alternative therapies can play in improving both the emotional and physical strains patients experience during the post-operative stage of recovery. A PubMed search was conducted using the following search terms (“alternative medicine” or “complementary medicine” or “integrative medicine” or “holistic medicine” or “natural medicine" or “mediation” or “aromatherapy” or “music” or “art” or “reiki” or “massage”) and (“surgery”) and (“pain”). Studies selected for this review include articles published or translated in English that addressed alternative medical interventions affecting pre-, peri-, or post-operative outcomes in breast biopsies, surgeries, or breast-related procedures. Eighteen articles fit the inclusion criteria, with seven addressing music, five addressing meditation, yoga, and guided imagery, five addressing massage, one addressing myofascial release, four addressing aromatherapy, two addressing acupuncture, and three addressing hypnosis. Most forms of alternative therapies offered some benefit to patients following breast-related procedures, many resulting in improvements in post-operative outcomes including pain, fatigue, energy, stress, anxiety, mood, and depression. The reviewed studies demonstrated numerous benefits to integrating alternative medicine into standardized therapy to improve postoperative outcomes. Most studies analyzed did not include placebo controls as including proper placebos was often not feasible. Future studies with larger sample sizes are needed to better quantify the benefits patients receive from these noninvasive, low-risk complementary therapies.

Efficacy of Auricular Acupuncture and Lavender Oil Aromatherapy in Reducing Preinterventional Anxiety in Cardiovascular Patients: A Randomized Single-Blind Placebo-Controlled Trial

Introduction: Auricular acupuncture at the "relaxation point" and lavender oil aromatherapy can reduce preoperative anxiety associated with increased mortality and morbidity. Data on the effect of combined auricular acupuncture and lavender oil aromatherapy in patients undergoing cardiovascular interventions with the use of local anesthesia or under conscious sedation are sparse. The authors sought to evaluate the efficacy of auricular acupuncture and lavender oil aromatherapy in reducing preinterventional anxiety in cardiovascular patients. Materials and Methods: Data of 80 consecutive patients undergoing diagnostic coronary angiography (n = 56) with or without percutaneous coronary intervention (n = 9) and right heart catheterization (n = 6), transcatheter aortic valve replacement (n = 17) and percutaneous mitral valve repair (MitraClip; n = 2) were analyzed. Patients were prospectively randomized to receive either preinterventional auricular acupuncture and lavender oil (Lavandula angustifolia) aromatherapy (verum group, n = 39) or combined sham auricular acupuncture and placebo oil aromatherapy (placebo group, n = 41). For the verum group bilateral auricular acupuncture was performed at the "relaxation point." State anxiety and blood pressure were assessed before and at 30 min after acupuncture and presternal oil application. State anxiety was defined as primary outcome measure and assessed using the Spielberger State Anxiety Inventory (STAI) for Adults form Y6. Intervention-specific anxiety was assessed by a 10-point numerical rating scale, and perceived treatment success by a single dichotomous question. Clinical blood pressure was further assessed. Results: After the intervention, the verum group had significantly decreased anxiety on the STAI compared with the placebo group (Δ = -4.18; 95% confidence interval = -8.31 to -0.05; p = 0.047). Significantly more patients reported subjective treatment success in the verum group (87.2%) than in the placebo group (65.9%, p = 0.035). No significant differences were observed regarding intervention-specific anxiety and blood pressure between the two groups. No serious adverse events occurred in any group. Conclusions: Combined auricular acupuncture and lavender oil aromatherapy can decrease preinterventional anxiety in cardiovascular patients and requires further investigation.

A Randomized Controlled Trial Examining the Effect of Aromatherapy Using the Damask Rose Essential Oil on Pre-operative Anxiety Levels

Background: Non-pharmacological care interventions like aromatherapy can be cost-effective and efficient ways to reduce anxiety and adverse results before surgery. Objectives: In this study, the efficacy of aromatherapy on pre-operative anxiety in patients undergoing Percutaneous Nephrolithotomy (PCNL) referring to Peymaniyeh Hospital in Jahrom-Iran was the main goal. Methods: This controlled-randomized trial was conducted on 38 patients that were randomly assigned to two groups: Control and Aromatherapy (Rosa damascena). The anxiety levels were recorded for all two groups the night before the surgery. On the day of surgery and after re-communication, patients were approached in a pre-operative holding area, and the intervention was performed. Data were collected over 11 months from June 2015 to May 2016. Results: The statistically significant difference after the intervention between the control and intervention groups indicated that Aromatherapy with Rosa damascene reduced the patient’s anxiety. Conclusions: This survey prepares evidence for the use of Damask rose as an anti-anxiety intervention. Using Damask rose as a nursing intervention helps nurses provide individualized care and helps patients control their anxiety.

The Efficacy of Lavender Aromatherapy in Reducing the Overcrowding-Related Anxiety in Health Care Workers

In general, emergency departments (EDs) are stressful workplaces with excessive workloads and time pressures. Crowding, which is an important problem worldwide disrupting ED functions, leads further increases in the stressors which health care workers are exposed to. Long-term exposure to stressors can lead to anxiety in health care workers. The aim of this study was to determine the effect of aromatherapy on crowding-related anxiety in ED health care workers. Crowding was measured simultaneously with the National Emergency Department Overcrowding Scale objectively and the Health Care Workers' Crowding Perception Evaluation Form subjectively. The state-trait anxiety level was measured at each crowding level according to the health care workers' perception. When perceived crowding was at severely overcrowding level, lavender oil aromatherapy was applied. Anxiety level was measured before and after aromatherapy. Aromatherapy was repeated 3 times on different days. A significant positive correlation was found between state anxiety level and perceived crowding (r = 0.415, p < 0.001). Aromatherapy was found to have a significant correlation in reducing the overcrowding-related anxiety in health care workers (p < 0.05). This study showed that there is a significant correlation between anxiety level and perceived crowding, and aromatherapy is related to a decrease in overcrowding-related anxiety. In EDs, lavender oil aromatherapy can be used as a complementary method in reducing the overcrowding-related anxiety. But further researches are needed to verify that aromatherapy has a causative effect on reducing overcrowding-related anxiety.

Essential oil therapy for the short-term treatment of behavioral and psychological symptoms of dementia: a monocentric randomized pilot study

BACKGROUND

The behavioral and psychological symptoms of dementia (BPSD) can be severely distressing for both patients and caregivers.

AIMS

This study assessed the efficacy of environmental diffusion essential oil therapy (EOT) combined with psychotropic drug therapy (group A) in BPSD management, compared with psychotropic drug therapy alone (group B). The stress responses of attending caregivers were also assessed.

METHODS

Thirty-two patients with dementia and BPSD were enrolled. The presence and severity of BPSD were assessed using the Italian version of the NPI-NH scale, which also measures the stress felt by professional caregivers. Global geriatric evaluations were performed to rule out acute diseases that could contribute to delirium and worsen patients' mental status.

RESULTS

Following treatment, the average NPI-NH value was significantly reduced in group A compared with group B (p < 0.001). Caregiver distress was also significantly reduced in group A (p < 0.01).

DISCUSSION

This pilot study showed that BPSD were better treated using EOT combined with standard pharmacological treatment, compared with standard pharmacological treatment alone. No adverse effects of EOT were observed. Reductions in caregiver distress could be due either to reductions in BPSD severity and frequency resulting in decreased caregiver burden, and/or the emotional benefit for caregivers of exposure to essential oils.

CONCLUSIONS

This study supports the combined use of EOT and psychotropic drugs in the treatment of BPSD. Essential oils may improve the wellbeing of both patients and caregivers, without adverse effects. Additionally, EOT is easy to administer by environmental diffusion.

Lavender Aromatherapy as a Nurse-Driven Intervention for Preoperative Anxiety

OBJECTIVE

To explore potential clinical applications, based on evidence and a nurse-driven test of change, of using lavender aromatherapy for preoperative anxiety as an intervention complementary to standard preoperative care.

DESIGN

A pre- versus postaromatherapy comparison using a visual analog scale (VAS).

SETTING

The preoperative department at a level 2 trauma hospital with 544 beds.

PARTICIPANTS

Forty-four surgical patients, including 29 female participants and 15 male participants.

INTERVENTION/MEASUREMENTS

Participants reported their anxiety on a VAS before receiving a lavender aromatherapy inhaler. Anxiety scores were measured again after receiving the lavender aromatherapy and shortly before participants left the preoperative area for surgery. A pre-post comparison of the two VAS anxiety measurements before and after receiving the lavender aromatherapy was completed, analyzed, and is discussed.

RESULTS

Mean anxiety scores were calculated for the pre- and postaromatherapy groups. Forty-eight percent of female participants (n = 29) reported a decrease in their anxiety after receiving preoperative lavender aromatherapy. Female participants reported higher preoperative anxiety scores and a larger decrease in their mean anxiety scores after receiving lavender aromatherapy when compared to male participants.

CONCLUSION

The use of a nurse-driven complementary intervention in the preoperative area was associated with a decrease in mean anxiety scores among female patients about to undergo elective surgery. However, cause and effect cannot be determined because of a lack of a control group and randomization. Opportunities exist with support from seasoned staff for nurses to incorporate safe, evidence-based complementary interventions into the current standard of care for preoperative anxiety.

Investigation of the Role of Complementary Medicine on Anxiety of Patients Before and After Surgery: A Review Study

Every year millions of patients undergo surgery worldwide. Anxiety is a common pre- and postoperative problem. Nonpharmacologic anxiety control has been demonstrated to be more suitable in patients. The objective of this study was to apprise the evidence of the effect of various complementary therapies on pre- and postoperative anxiety among patients. A comprehensive literature search was made on Web of Science, Scopus, Cochrane, PubMed Irandoc, SID Science, ScienceDirect, Ovid, Mag Iran, and Google Scholar for original research studies published between 1980 and 2019. Original articles that reported the effect of complementary therapies in patients undergoing surgery were included. Ninety-six studies were analyzed. All of the studies have documented the effects of complementary therapies on improving pre- and postoperative outcomes of patients. Although methods varied considerably, most of the studies included in this review reported positive results. Therefore, there is some evidence that complementary therapies can lead to positive pre- and postoperative outcomes. Therefore, the efficiency and use of complementary medicine, along with the use of therapeutic techniques in classical medicine, can provide a new model for reducing anxiety before and after surgery. It is recommended that nurses conduct additional reviews or clinical studies so that effective approaches to integrated medical care can be developed and patients' health enhanced.

Effects of non-pharmacological interventions on preoperative anxiety and postoperative pain in patients undergoing breast cancer surgery: A systematic review

BACKGROUND

Poorly managed preoperative anxiety and pain were reported to slow the postoperative recovery of breast cancer patients. Thus, proactive management using non-pharmacological interventions becomes essential for decreasing opioid or anxiolytics consumption, anxiety level, pain intensity, postoperative complications and improving patients' haemodynamics and satisfaction with care.

PURPOSE

To identify, analyse and synthesise the effects of non-pharmacological interventions on preoperative anxiety and acute postoperative pain in women undergoing breast cancer surgery.

METHOD

For this systematic review, 12 databases including Ovid Nursing, PsycInfo, British Nursing Index, CINAHL, Cochrane Library were searched to identify relevant studies. A total of 6,012 articles were identified from the search, six RCTs and one quasi-experimental study that met the inclusion criteria were included after eligibility screening. Narrative synthesis was used to analyse data extracted from the included articles. The review adhered to the PRISMA guideline.

RESULTS

Twelve outcomes were measured in the included studies, including preoperative anxiety, and acute postoperative pain. Music, massage, aromatherapy and acupuncture were the interventions delivered. Music had a small-to-large effect size and aromatherapy had a small effect size on reducing preoperative anxiety. Also, music had a large effect size whilst acupuncture had a medium effect size on minimising postoperative pain in women undergoing breast cancer surgery.

CONCLUSION

Music, aromatherapy and acupuncture appeared to be effective for reducing preoperative anxiety and postoperative pain in women undergoing breast cancer surgery. However, the small number of studies available for each intervention prevents conclusive statements about which the most effective method.

IMPLICATION FOR CLINICAL PRACTICE

A nursing care pathway that standardises the use of non-pharmacological interventions for the management of both preoperative anxiety and postoperative pain in breast cancer surgery patients should be developed.

Effect of aromatherapy on preoperative anxiety in adult patients: A meta-analysis of randomized controlled trials

BACKGROUND

and purpose: Preoperative anxiety is an important factor for postoperative complications, and many patients are using aromatherapy to relieve preoperative anxiety. This study aimed to evaluate the effect of aromatherapy on preoperative anxiety in adult patients.

METHODS

An electronic search of six databases (Cochrane Library, PubMed, Embase, CINAHL, CNKI, and WanFang Data) was conducted for full-text publications of trials published from the inception of the databases to February 20, 2020. All randomized controlled trials (RCTs) where aromatherapy was used for treatment of preoperative anxiety were included. Interventions included all types of aromatherapy compared to standard care or placebo. The primary outcome was self-rated anxiety and the secondary outcome was adverse effect. Two researchers independently screened and extracted relevant data. A random-effects model was utilized to calculate the effect size as mean difference (MD).

RESULTS

Our search retrieved 347 records. Thirteen trials were included for qualitative analysis, of which ten RCTs with 750 patients were included for meta-analysis. Most studies had a high or unclear selection and performance bias. Overall, aromatherapy was found to decrease preoperative anxiety significantly compared to the control group (MD = -3.95, 95%CI [-6.36, -1.53], P = 0.001). According to subgroup analysis, most subgroups showed a significant effect of aromatherapy on preoperative anxiety, except for the no treatment subgroup (MD: 5.40, 95%CI: 7.76 to 0.71) and female subgroup (MD: 3.96, 95%CI: 9.19 to 1.27).

CONCLUSION

Aromatherapy may be an effective complementary treatment for preoperative anxiety. Nevertheless, due to methodological limitations of the included trials, further studies with strict control of the research design are required for firm recommendations.

The effectiveness of inhaled Cannabis flower for the treatment of agitation/irritability, anxiety, and common stress

BACKGROUND

An observational research design was used to evaluate which types of commonly labeled Cannabis flower product characteristics are associated with changes in momentary feelings of distress-related symptoms.

METHODS

We used data from 2306 patient-directed cannabis administration sessions among 670 people who used the real-time Cannabis effects recording software, Releaf App, between June 6, 2016, and February 23, 2019, for tracking the effects of Cannabis flower consumption. Fixed effects multivariable panel regression techniques were used to establish overall relief by symptom type and to determine which labeled product characteristics (e.g., subspecies/subtype, inhalation method, and major cannabinoid contents) showed the strongest correlation with changes in momentary feelings of agitation/irritability, anxiety, and stress, along with experienced side effects.

RESULTS

In total, a decrease in symptom intensity levels was reported in 95.51% of Cannabis usage sessions, an increase in 2.32% of sessions, and no change in 2.16% of sessions. Fixed effects models showed, on average, respondents recorded a maximum symptom intensity reduction of 4.33 points for agitation/irritability (SE = 0.20, p < 0.01), 3.47 points for anxiety (SE = 0.13, p < 0.01), and 3.98 for stress (SE = 0.12, p < 0.01) on an 11-point visual analog scale. Fixed effects regressions showed that, controlling for time-invariant user characteristics, mid and high tetrahydrocannabinol (THC) levels were the primary independent predictor of increased symptom relief, and that when broken out by symptom type, this effect was only statistically significant for our largest sample of users, those reporting anxiety rather than agitation/irritability or stress. Cannabidiol (CBD) levels were generally not associated with changes in symptom intensity levels. In a minority of cannabis use sessions (< 13%), cannabis users reported anxiogenic-related negative side effects (e.g., feeling anxious, irritable, paranoid, rapid pulse, or restless), whereas in a majority of sessions (about 66%), users reported positive anxiolytic side effects (e.g., feeling chill, comfy, happy, optimistic, peaceful, or relaxed).

CONCLUSIONS

The findings suggest the majority of patients in our sample experienced relief from distress-related symptoms following consumption of Cannabis flower, and that among product characteristics, higher THC levels were the strongest predictors of relief.

Uses of Complementary and Alternative Medicine for Perioperative and Other Patients

The efficacy of using complementary and alternative medicine (CAM) is supported by the literature to decrease preoperative anxiety, postoperative pain and opioid requirements, as well as nausea and vomiting and to improve severity of headaches and increase wound healing. Nursing care includes interventions using CAs for treatment of a range of patient needs. Being supportive while educating parents and patients demonstrates altruism, which also is beneficial for improving health outcomes with CAM.

Pain Management in Breast Surgery: Recommendations of a Multidisciplinary Expert Panel-The American Society of Breast Surgeons

Opioid overdose accounted for more than 47,000 deaths in the United States in 2018. The risk of new persistent opioid use following breast cancer surgery is significant, with up to 10% of patients continuing to fill opioid prescriptions one year after surgery. Over prescription of opioids is far too common. A recent study suggested that up to 80% of patients receiving a prescription for opioids post-operatively do not need them (either do not fill the prescription or do not use the medication). In order to address this important issue, The American Society of Breast Surgeons empaneled an inter-disciplinary committee to develop a consensus statement on pain control for patients undergoing breast surgery. Representatives were nominated by the American College of Surgeons, the Society of Surgical Oncology, The American Society of Plastic Surgeons, and The American Society of Anesthesiologists. A broad literature review followed by a more focused review was performed by the inter-disciplinary panel which was comprised of 14 experts in the fields of breast surgery, anesthesiology, plastic surgery, rehabilitation medicine, and addiction medicine. Through a process of multiple revisions, a consensus was developed, resulting in the outline for decreased opioid use in patients undergoing breast surgery presented in this manuscript. The final document was reviewed and approved by the Board of Directors of the American Society of Breast Surgeons.

Ambient Scent as a Positive Distraction in Long-Term Care Units: Theory of Supportive Design

AIM

This study was designed to explore the associations between an ambient scent environment and residents' wellness in long-term care facilities.

BACKGROUND

The number of older adults living in an institutional setting has been steadily but slowly increasing. Because of a higher chance of having psychological disorders among people living in institutional settings than people living in noninstitutional settings, providing a supportive institutional setting is critical to enhance their wellness. The theory of supportive design suggests healthcare facilities can lower people's stress levels via three conditions (i.e., perceived control, social support, and positive distractions).

METHOD

A single-blind and placebo-randomized controlled study investigated the impacts of ambient scent environment, as a positive distraction, on residents' depression levels. The recruited residents (N = 58) were randomly assigned into either the intervention group, which received a 1% dilution of lavender scent for 2 weeks nearby their bedside or the placebo group, which received a nonscent for 2 weeks.

RESULTS

Their depression levels were measured by the Geriatric Depression Scale. Based on the t tests, both intervention and placebo groups had improvement in depression, indicating a placebo effect of lavender scent. Further regression analyses explored the interaction effects of built environments (e.g., building, distance to a ventilation system, and square footage). However, no statistically significant impact of the built environment was found.

CONCLUSION

Despite a placebo effect of ambient scent environment and nonsignificant built environment on depression, this study has valuable implications of being a positive distraction during the healing process as developed by the Theory of Supportive design.

A Feasibility Study of Lavender Aromatherapy in an Awake Craniotomy Environment

PURPOSE

Integrative medicine interventions are needed for awake craniotomies, as many patients experience anxiety. Lavender aromatherapy significantly reduces anxiety or pain in a variety of surgical procedures. This feasibility study used lavender aromatherapy during awake craniotomies to determine the number of patients who would consent and complete the study, the technicality of lavender aromatherapy use, and acceptance by operating room (OR) staff.

METHODS

We approached 40 consecutive patients (≥18 years old). Exclusion criteria were pulmonary issues or sensitivity to lavender. Outcome measures in consented patients were enrollment and completion rates, anxiety and pain as measured by the Visual Analog Scale for Anxiety (VAS-A) and Visual Analog Scale for Pain (VAS-P), and satisfaction with pain control using the Patient Opinion of Pain Management (POPM) survey.

RESULTS

Of the 40 patients approached, 4 declined participation or had their surgery cancelled. Of the remaining 36, 4 required increased sedation during surgery and 1 was unable to detect lavender. Thus, 31 patients (77.5%) completed the study. VAS-A and VAS-P scores trended lower after lavender inhalation, but the difference did not reach statistical significance. There was a slight increase in VAS-P score at the OR1 time point. Expectancy for reduction in both anxiety and pain were not significantly different. Improvement in anxiety also was not different, while improvement in pain trended lower (P=0.025). POPM results indicated the majority of patients were either "satisfied" or "very satisfied" with pain management.

CONCLUSIONS

This study demonstrated 77.5% completion and the ability to integrate lavender aromatherapy into the OR. Thus, we plan to conduct a randomized clinical trial to assess efficacy of lavender aromatherapy.

Effects of lavender on anxiety: A systematic review and meta-analysis

BACKGROUND

Anxiety is one of the uprising psychiatric disorders of the last decades and lavender administration has been traditionally suggested as a possible treatment. The objective of this review is to assess the efficacy of lavender, in any form and way of administration, on anxiety and anxiety-related conditions.

METHODS

The PRISMA guidelines were followed. Retrieved data were qualitatively and quantitatively synthesized. Randomized Controlled Trials (RCTs) and Non-Randomized Studies (NRSs) which investigated the efficacy of lavender, in any form and way of administration, on patients with anxiety, involved in anxiety-inducing settings or undergoing anxiety-inducing activities, compared to any type of control, without language restrictions, were identified through electronic database searches. Medline via PubMed, Scopus, Web of Science, Cochrane Library, EMBASE, and Google Scholar were systematically searched. All databases were screened up to November 2018. Risk of bias was assessed with the Cochrane risk-of-bias tool and the following domains were considered: randomization, allocation sequence concealment, blinding, incomplete outcome data, selective outcome reporting, and other biases.

RESULTS

65 RCTs (7993 participants) and 25 NRSs (1200 participants) were included in the qualitative synthesis and 37 RCTs (3964 participants) were included in the quantitative synthesis. Overall, the qualitative synthesis indicated that 54 RCTs and 17 NRSs reported at least a significant result in favor of lavender use for anxiety. The quantitative synthesis showed that lavender inhalation can significantly reduce anxiety levels measured with any validated scale (Hedges' g = -0.73 [95% CI -1.00 to -0.46], p < 0.00001, 1682 participants), as well as state anxiety (Spielberger's state-trait anxiety inventory (STAI)-State mean difference = -5.99 [95% CI -9.39 to -2.59], p < 0.001, 901 participants) and trait anxiety (STAI-Trait mean difference = -8.14 [95% CI -14.44 to -1.84], p < 0.05, 196 participants). Lavender inhalation did not show a significant effect in reducing systolic blood pressure as a physiological parameter of anxiety. A significant effect in diminishing anxiety levels was also found in favor of the use of oral Silexan® 80 mg/die for at least 6 weeks (Hamilton Anxiety Scale mean difference = -2.90 [95% CI -4.86 to -0.95], p = 0.004, 1173 participants; Zung Self-rating Anxiety Scale mean difference = -2.62 [95% CI -4.84 to -0.39], p < 0.05, 451 participants) or of the administration of massage with lavender oil (Hedges' g = -0.66 [95% CI -0.97 to -0.35], p < 0.0001, 448 participants).

DISCUSSION

The most important limitation of this review is the low average quality of available studies on the topic. The majority of included RCTs were characterized by a high overall risk of bias. Another limitation regards the heterogeneity of study designs, especially with regard to non-oral ways of administration. Overall, oral administration of lavender essential oil proves to be effective in the treatment of anxiety, whereas for inhalation there is only an indication of an effect of reasonable size, due to the heterogeneity of available studies. Lavender essential oil administered through massage appears effective, but available studies are not sufficient to determine whether the benefit is due to a specific effect of lavender. Further high-quality RCTs with more homogeneous study designs are needed to confirm these findings. Available information outlines a safe profile for lavender-based interventions, although more attention should be paid to the collection and reporting of safety data in future studies. Considering these findings, since treatments with lavender essential oil generally seem safe, and, in the case of inhalation, also simple and inexpensive, they are a therapeutic option which may be considered in some clinical contexts.

How Strong is the Evidence for the Anxiolytic Efficacy of Lavender?: Systematic Review and Meta-analysis of Randomized Controlled Trials

PURPOSE

Although lavender is purported to possess anxiolytic and sedative properties and is often recommended for relieving anxiety, the efficacy of lavender has not been well established. Thus, this review aimed to evaluate the anxiolytic effects of lavender aromatherapy.

METHODS

Ten data bases were searched for studies published between 2000 and 2018. Randomized controlled trials investigating the anxiolytic effects of lavender aromatherapy with any type of application for persons with or without clinical anxiety were included. The outcome variables included self-rated anxiety, vital signs, and salivary cortisol and chromogranin A (CgA) levels. In the meta-analysis, standardized mean difference and 95% confidence interval were calculated as effect measures by applying the random effect model and inverse variance method.

RESULTS

Twenty-two trials met our inclusion criteria. Lavender aromatherapy was found to have favorable effects in relieving anxiety (Hedges' ĝ = -0.65; 95% CI, -0.84 to -0.46) and decreasing systolic blood pressure (ĝ = -0.22; 95% CI, -0.43 to -0.02), heart rate (ĝ = -0.53; 95% CI, -0.74 to -0.32), and salivary cortisol (ĝ = -1.29; 95% CI, -2.23 to -0.35) and CgA (ĝ = -2.29; 95% CI, -3.24 to -1.34) levels. However, the meta-analysis did not reveal any significant effects of lavender on diastolic blood pressure (effect size: -0.17; 95% CI, -0.37-0.04).

CONCLUSION

Aromatherapy using lavender oil might have favorable effects on anxiety and its physiological manifestations. Future studies are recommended with an emphasis on methodological quality. In nursing practice, it is suggested that lavender aromatherapy be included in programs intended to manage anxiety in patients across diverse healthcare settings.

Preoperative Anxiety in Patients Undergoing Outpatient Cancer Surgery

OBJECTIVE

Our primary research aim was to determine the prevalence of preoperative anxiety in patients undergoing outpatient cancer surgery. Our secondary aim was to examine the association between preoperative anxiety and negative intraoperative and postoperative outcomes in patients undergoing outpatient cancer surgery, including increased anesthesia requirements, postoperative nausea and vomiting (PONV), extended overnight stay, total length of stay (LOS), transfer to hospital, surgical complications, and postoperative visits to urgent care centers (UCC).

METHODS

We conducted a retrospective cohort study to investigate the prevalence of preoperative anxiety and its association with postoperative outcomes in patients undergoing outpatient cancer surgery. Our retrospective cohort included 10,048 outpatient procedures performed on 8683 patients at a large comprehensive cancer center between January 1, 2016, and April 30, 2018.

RESULTS

The analysis included 8665 patients undergoing procedures at an outpatient facility over 16 months; 16.7% had preoperative anxiety. In patients with preoperative anxiety, higher rates of adverse outcomes were seen, including PONV (adjusted difference 1.8%, 95% confidence interval [CI] 0.12%, 3.4%, P = 0.029), unplanned overnight admission (adjusted difference 1.1%, 95% CI 0.07%, 2.0%, P = 0.021), and urgent care visits within 30 days (adjusted difference 1.5%, 95% CI 0.44%, 2.6%, P = 0.002).

CONCLUSIONS

Even assuming a causal relationship between preoperative anxiety and postoperative outcomes, preventing one instance of PONV would require treating at least 30 patients for anxiety, and preventing longer-term outcomes such as urgent care visits or readmissions within 30 days would require treating even larger numbers of patients. Future studies should attempt to elucidate the causal pathway between preoperative anxiety and postoperative adverse events in outpatients undergoing outpatient cancer surgery.

Plants of the Genus Lavandula: From Farm to Pharmacy

The Lavandula genus, belonging to the Lamiaceae, includes 39 species, with nearly 400 registered cultivars. Lavandula are worldwide plants that occur over the Mediterranean, Europe, North Africa, southwest Asia to southeast India. Lavandula plants have been used since ancient time to flavor and preserved food, to treat diseases including wound healing, sedative, antispasmodic, microbial and viral infections. Numerous researches have described the chemical composition and the primary components of lavender oils are the monoterpenoids (linalool, linalyl acetate, 1,8-cineole, β-ocimene, terpinen-4-ol, and camphor), sesquiterpenoids (β-caryophyllene and nerolidol) and other terpenoid compounds (e.g., perillyl alcohol). The high concentrations of linalyl acetate make them attractive in perfumery, flavoring, cosmetics and soap industries. Currently, data on the antimicrobial activity of lavender plants have been scientifically confirmed. Indeed, lavender essential oils possess wide spectra of biological activities such as antispasmodic, carminative, analgesic, sedative, hypotensive, antiseptic, antimicrobial, antifungal, antidiuretic and general tonic action. In addition, clinical studies support their uses as treatment of health conditions. However, further clinical studies are necessary to define the magnitude of the efficacy, mechanisms of action, optimal doses, long-term safety, and, potential side effects of lavender plants.

The Efficacy of Lavender Aromatherapy in Reducing Preoperative Anxiety in Ambulatory Surgery Patients Undergoing Procedures in General Otolaryngology

Background

Preoperative anxiety is a common problem in hospitals and other health care centers. This emotional state has been shown to negatively impact patient satisfaction and outcomes. Aromatherapy, the therapeutic use of essential oils extracted from aromatic plants, may offer a simple, low-risk and cost-effective method of managing preoperative anxiety. The purpose of this study was to evaluate the efficacy of lavender aromatherapy in reducing preoperative anxiety in ambulatory surgery patients undergoing procedures in general otolaryngology.

Methods

A prospective and controlled pilot study was conducted with 100 patients who were admitted to New York-Presbyterian/Weill Cornell Medical Center for ambulatory surgery from January of 2015 to August of 2015. The subjects were allocated to two groups; the experimental group received inhalation lavender aromatherapy in the preoperative waiting area while the control group received standard nursing care. Both groups reported their anxiety with a visual analog scale (VAS) upon arriving to the preoperative waiting area and upon departure to the operating room.

Results

According to a Welch's two sample t-test, the mean reduction in anxiety was statistically greater in the experimental group than the control group (p = 0.001).

Conclusion

Lavender aromatherapy reduced preoperative anxiety in ambulatory surgery patients. This effect was modest and possibly statistically significant. Future research is needed to confirm the clinical efficacy of lavender aromatherapy.

Essential oil of lavender in anxiety disorders: Ready for prime time?

Anxiety disorders are some of the most common psychiatric disorders, with potentially debilitating consequences on individual function. Existing pharmacotherapies for anxiety disorders are limited by delay to therapeutic effect, dependence, tolerance, withdrawal, and abuse potential. Therefore, safe and evidence-based complementary or alternative therapies may be important allies in the care of patients with anxiety disorders. Essential oils are lipophilic and concentrated botanical extracts that exhibit many properties of drugs, although they are not Food and Drug Administration approved and have limitations characteristic of herbal preparations. Lavender essential oil has an extensive anecdotal history of anxiolytic benefit that has recently been supported by clinical efficacy studies. The 2 primary terpenoid constituents of lavender essential oil, linalool and linalyl acetate, may produce an anxiolytic effect in combination via inhibition of voltage-gated calcium channels, reduction of 5HT1A receptor activity, and increased parasympathetic tone. The objectives of this article are to provide a brief overview of lavender oil in aromatherapy, explore variability in the constituents of lavender oil, summarize its pharmacology and safety profile, as well as describe its body of research that has been conducted for anxiety.
