Essential Oils to Reduce Postoperative Nausea and Vomiting

The effect of an aromatic solution applied after percutaneous nephrolithotomy on sore throat, thirst, and nausea-vomiting: A randomised controlled trial

BACKGROUND AND PURPOSE

Common postoperative symptoms are known to impede recovery, indicating the necessity for non-pharmacological alternatives to address these symptoms. This study aimed to investigate the effect of an aromatic solution prepared from lavender and ginger oil on sore throat, thirst, and nausea-vomiting after percutaneous nephrolithotomy (PNL) surgery.

MATERIALS AND METHODS

The trial used an experimental, double-blind randomised controlled group design with three arms. It was conducted between 2021 and 2023 in the urology department of a hospital, involving 110 patients (37 experimental, 37 placebo, 36 control) who underwent PNL. A personal information form, a visual analogue scale (VAS) for sore throat and thirst, and a verbal descriptive scale (VDS) for nausea and vomiting were used. The prepared aromatic solution was applied as a mouth spray at 0, 2, 4, 6, and 8 h postoperatively.

RESULTS

A statistically significant decrease in sore throat scores was observed in the experimental group compared to the placebo and control groups following the intervention. Thirst levels decreased in both the placebo and experimental groups, with the experimental group showing lower thirst scores than the other groups. Additionally, the experimental group showed a significant reduction in nausea and vomiting scores compared to the other groups.

CONCLUSION

This study found that the aromatic solution had beneficial effects on sore throat, thirst, and nausea-vomiting in the postoperative period. To our knowledge, this is among the first studies exploring combined effects of lavender and ginger oils on postoperative symptoms after PNL surgery, potentially offering new insights to the literature.

Examining the Effect of Peppermint Oil on Postoperative Nausea After Cervical Surgery

ABSTRACT

PURPOSE: The aim of this study was to investigate the effect of peppermint oil aromatherapy on postoperative nausea and vomiting (PONV) and hemodynamic parameters in patients undergoing single-level cervical surgery. METHODS: This prospective randomized controlled study consisted of 76 single-level cervical surgery patients admitted to the neurosurgery department between March 2021 and November 2022. The patients were randomized into 2 groups: the intervention group received peppermint oil aromatherapy through inhalation, whereas the control group received routine clinical treatment. Both groups were observed for the presence and severity of PONV, the use of antiemetics, and hemodynamic parameters at minute 5, 35, 65, and 95, and at hour 2, 6, 12, and 24 after surgery. RESULTS: In the control group, 18 (47.8%) patients experienced nausea, 11 (28.9%) experienced vomiting, and 7 (18.4%) used antiemetics. In contrast, the intervention group included only 2 (5.3%) patients who experienced nausea, and none of those patients experienced vomiting or used antiemetics. It was determined that peppermint oil had a 40% effect on reducing PONV, 34% effect on reducing postoperative antiemetic use, and 75% effect on reducing severity of nausea. Hemodynamic parameters did not differ significantly between the 2 groups. The systolic blood pressure of the control group was significantly greater than that of the intervention group only at minute 95 and at hour 24 after surgery. CONCLUSIONS: The results suggest that the use of peppermint oil aromatherapy can have a positive effect on reducing the presence and severity of PONV and the need for antiemetic medication in patients undergoing single-level cervical surgery.

Aromatherapy for the prevention of postoperative nausea and vomiting: A systematic review and meta-analysis

Objectives

Postoperative nausea and vomiting (PONV) are common complications following surgical procedures. While drug-based treatments are standard, there is increasing interest in nonpharmacological alternatives, such as aromatherapy, due to potential benefits and minimal side effects. This study aimed to assess the effectiveness of aromatherapy in preventing PONV.

Materials and Methods

A comprehensive systematic review and meta-analysis were conducted using PubMed, Cochrane Library, EMBASE, and CINAHL databases for studies published up to May 2023. The included studies were randomized controlled trials (RCTs) and nonrandomized studies of interventions that examined the impact of aromatherapy on PONV. The risk of bias was assessed, and the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was employed to evaluate the certainty of the evidence.

Results

Eleven studies were selected for review, with eight RCTs included in the meta-analysis. Aromatherapy effectively reduced postoperative nausea severity (standardized mean difference [SMD]: -0.93, 95% confidence interval [CI]: -1.64 to -0.22; P = 0.010), but the reduction in vomiting episodes was not statistically significant (SMD: -0.81, 95% CI: -1.98-0.37; P = 0.180). Subgroup analysis indicated that ginger essence, lavender, and peppermint oils were particularly effective in managing postoperative nausea. However, due to significant statistical heterogeneity and potential biases in the studies, the results should be interpreted with caution. The certainty of the evidence, as evaluated by the GRADE approach, was low.

Conclusion

Preliminary evidence supports the potential benefit of aromatherapy in reducing the severity of postoperative nausea. However, given the low certainty of current evidence, more rigorous and standardized research is needed. The safety, affordability, and potential benefits to patient comfort make aromatherapy a promising area for further research in postoperative care.

Perceived Barriers to Administration of Aromatherapy in Nurses Caring for Pediatric Patients With Postoperative Nausea and Vomiting: An Evidence-based Practice Project

INTRODUCTION

Postoperative nausea and vomiting (PONV) is prevalent among surgical patients, causing hospitalizations, extended stays, and patient dissatisfaction. Children are twice as likely to experience PONV than adult patients. Complementary therapy holds promise for PONV treatment but meets clinical use barriers. We explored perioperative nurses' perceived barriers to the use of complementary aromatherapy.

METHOD

Presurvey and postsurveys assessed nurses' (n = 27) knowledge and barriers to aromatherapy use before and after an educational in-service.

RESULTS

Primary PONV treatment involved antiemetics. Barriers to aromatherapy included product availability, caregiver refusal, and patient-specific factors. Post-in-service, the nurses felt more familiar with aromatherapy and inclined to use it.

DISCUSSION

Increased education and guidelines on aromatherapy promote its incorporation into clinical practice. Institutional policies addressing the selection, administration, documentation, and monitoring of aromatherapy should be established to ensure the consistency and standardization of its use.

Dietary agents in the prevention of radiation-induced nausea and vomiting (RINV): review addressing the scientific observations, benefits, lacunae and future direction

PURPOSE

Radiation-induced Nausea and Vomiting (RINV) is an important side effect and conservative estimates are that 50-80% of the patients undergoing curative radiotherapy (RT) will experience some sought of retching, nausea, and/or vomiting during the course of their treatment. Conventionally, antiemetic drugs like the 5-hydroxytryptamine receptor antagonists and steroids are the mainstay of treatment. However, the use of these agents, especially steroids, can cause side effects and thereby negate the proposed benefits. The antiemetic effects of Centella asiatica (Indian pennywort), Hippophae rhamnoides (Sea buckthorn), oil of Mentha spicata (Spearmint) and the rhizomes of Zingiber officinale (ginger) have been addressed.

CONCLUSIONS

Results indicate that Indian pennywort, Sea buckthorn, Spearmint oil and ginger are beneficial in mitigating RINV. Also, of the four plants investigated in preclinical models of study, mint oil and ginger seem to be more useful and merit structured systematic translational studies to ascertain the benefit of these two agents.

What Does a Community Think About Aromatherapy?

The awareness and usage of aromatherapy applications are increasing day by day in society. The current study aims to evaluate the thoughts and attitudes of individuals toward aromatherapy in Türkiye and to determine factors affecting the use of aromatherapy. This community-based descriptive study is conducted throughout Türkiye. Nine hundred eighty-five questionnaires were suitable for data quality. SPSS 23.0 statistical package program was used, and the statistical significance level was accepted as P value of less than .05. Approximately 72.4% of the participants have heard of aromatherapy. The rate of hearing about the concept of aromatherapy was found to be statistically significantly higher among women (P = .000), those residing in a province/district (P = .011), and those working in an income-generating positions (P = .003). It was determined that 58.9% of the participants used any essential oil. The 5 most commonly used essential oils are lavender, tea tree, peppermint, rose, and thyme, respectively. The rate of essential oil use in women is higher than in men (P = .000). The conditions in which essential oils are most frequently used are to provide beauty to the skin (51.7%), skin diseases (51.0%), and respiratory tract diseases (46.0%), respectively. The most common sources of information about the essential oils used by the participants are the Internet/social media (57.6%) and pharmacists (53.4%). The results of this research revealed that the awareness and use of aromatherapy practice in the community are high according to the literature. Considering the high tendency to use these products among the public, physicians, pharmacists, and nurses must provide consultancy services on the use of these products.

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).

The Effect of Peppermint (Mentha piperita) Extract on the Severity of Nausea, Vomiting and Anorexia in Patients with Breast Cancer Undergoing Chemotherapy: A Randomized Controlled Trial

Background and Objective: Nausea, vomiting, and anorexia are the most common side effects reported in cancer patients undergoing chemotherapy. The present study aimed to determine the effect of peppermint extract on the severity of nausea, vomiting, and anorexia in patients with breast cancer undergoing chemotherapy. Methods and Materials: In this randomized controlled trial, we selected 84 patients with breast cancer undergoing chemotherapy. They were then assigned to 2 groups of experimental and control (n = 42, each) using block randomization. Patients in the experimental group received 40 drops of peppermint extract mixed in 20 cc of tap water every 8 hours, while patients in the control group received 40 drops of distilled water mixed in 20 cc of tap water every 8 hours. The severity of nausea, vomiting, and anorexia was measured and recorded before the intervention, and immediately, 24 and 48 hours after the chemotherapy using the Visual Analogue Scale. Statistical analysis of the data was conducted using SPSS software version 21. Results: The results of the present study revealed that there was a significant difference between the 2 groups at 24 and 48 hours after the chemotherapy (P < .05), so that the mean score of the severity of nausea, vomiting, and anorexia in the experimental group was lower than in the control group (P < .05). Conclusion: The use of peppermint as a method in complementary medicine may improve nausea, vomiting, and anorexia in patients with breast cancer undergoing chemotherapy. Further studies with greater sample size and longer follow-up period are needed to confirm the current findings.

Entrapment of Citrus limon var. pompia Essential Oil or Pure Citral in Liposomes Tailored as Mouthwash for the Treatment of Oral Cavity Diseases

This work aimed at developing a mouthwash based on liposomes loading Citrus limon var. pompia essential oil or citral to treat oropharyngeal diseases. Vesicles were prepared by dispersing phosphatidylcholine and pompia essential oil or citral at increasing amounts (12, 25 and 50 mg/mL) in water. Transparent vesicle dispersions were obtained by direct sonication avoiding the use of organic solvents. Cryogenic transmission electron microscopy (cryo-TEM) confirmed the formation of unilamellar, spherical and regularly shaped vesicles. Essential oil and citral loaded liposomes were small in size (~110 and ~100 nm, respectively) and negatively charged. Liposomes, especially those loading citral, were highly stable as their physico-chemical properties did not change during storage. The formulations were highly biocompatible against keratinocytes, were able to counteract the damages induced in cells by using hydrogen peroxide, and able to increase the rate of skin repair. In addition, liposomes loading citral at higher concentrations inhibited the proliferation of cariogenic bacterium.
