Anticholinergic Syndrome and Supraventricular Tachycardia Caused by Lavender Tea Toxicity

The Effect of Aromatherapy on Hemodialysis-Related Nausea: A Case Report

BACKGROUND: After hemodialysis, complications may occur and one of them that problematic is hemodialysis-related nausea. Information is still unclear about aromatherapy concerning nausea-related to hemodialysis. This study aimed to describe the effect of aromatherapy on nausea after hemodialysis procedures. CASE PRESENTATION: A 51-year-old female, undergoing routine hemodialysis, experienced severe hemodialysis-related nausea. Her nausea occurred a day after dialysis and existed for 3–4 days and this repeated as a cycle that affected her appetite, food intake, and general condition. The daily measurements of nausea used the visual analog scale and the nausea severity scale before and after the intervention. In addition, a manual book with a packet containing nausea education, protocol of intervention, and monitoring sheets, was provided. For two weeks, the application of two drops of lavender aromatherapy was given on a humid cotton swab and inhaled for 5 min. In addition, education explained oral hygiene using warm water when waking up in the morning and before eating food. There was a decrease in the intensity of nausea from severe to none based on daily measurements and from severe nausea (score: 21) to moderate nausea (score: 10) after the 2-weeks intervention. Thus, the patient could enjoy eating without any uncomfortable feeling of nausea. CONCLUSION: Lavender aromatherapy was demonstrated as a complementary therapy in overcoming nausea after dialysis among CKD patients. This report could provide a novel therapeutic modality for hemodialysis patients suffering hemodialysis-related nausea.

Blockade of voltage-dependent K+ channels by benztropine, a muscarinic acetylcholine receptor inhibitor, in coronary arterial smooth muscle cells

We investigated the effect of the acetylcholine muscarinic receptor inhibitor benztropine on voltage-dependent K+ (Kv) channels in rabbit coronary arterial smooth muscle cells. Benztropine inhibited Kv currents in a concentration-dependent manner, with an apparent IC50 value of 6.11 ± 0.80 μM and Hill coefficient of 0.62 ± 0.03. Benztropine shifted the steady-state activation curves toward a more positive potential, and the steady-state inactivation curves toward a more negative potential, suggesting that benztropine inhibited Kv channels by affecting the channel voltage sensor. Train pulse (1 or 2 Hz)-induced Kv currents were effectively reduced by the benztropine treatment. Furthermore, recovery time constants of Kv current inactivation increased significantly in response to benztropine. These results suggest that benztropine inhibited vascular Kv channels in a use (state)-dependent manner. The inhibitory effect of benztropine was canceled by pretreatment with the Kv 1.5 inhibitor, but there was no obvious change after pretreatment with Kv 2.1 or Kv7 inhibitors. In conclusion, benztropine inhibited the Kv current in a concentration- and use (state)-dependent manner. Inhibition of the Kv channels by benztropine primarily involved the Kv1.5 subtype. Restrictions are required when using benztropine to patients with vascular disease.

A sabbath in the emergency room or a case of anticholinergic toxicity?

We report the case of a 32-year-old Italian man admitted to our emergency room for visual disturbances with blurred vision, anisocoria and temporal headache suddenly occurred in absence of other neurological symptoms. A diagnosis of Datura stramoniuminduced anticholinergic toxicity was done. With our work, we want to highlight the importance of a meticulous clinical examination, including papillary diameter and reflexes, combined with a detailed history of the patient in the emergency room. Anticholinergic toxicity is a medical emergency. The diagnosis is always clinical, and it can represent a challenge for the emergency clinicians because it can mimic several neurological diseases, including acute stroke and seizures, but early diagnosis is crucial to avoid severe complications and management errors.

A randomized placebo-controlled study of aromatherapy for the treatment of postoperative nausea and vomiting

OBJECTIVE

The purpose of this study was to compare the aromatherapy treatment effects on PONV patients using ginger, lavender and rose oils and a placebo.

DESIGN

A randomized 4-armed placebo controlled study.

SETTING

Gaziosmanpasa University, School of Medicine, Health Research and Application Center.

INTERVENTION

The total of 184 patients were randomized into 4 groups: Aromatherapy with lavender essential oil (Lavender group), with rose essential oil (Rose group), with ginger essential oil (Ginger group) or with pure water (Placebo group).

MAIN OUTCOME MEASURES

Postoperative nausea (0-3 Likert type; 0=no nausea, 1=some, 2=a lot, 3=severe) and vomiting scores (0-3 Likert type; 0=no vomiting, 1 = 1 time, 2 = 2 or 3 time, 3 = 4 times and up) and antiemetic medication requirement.

RESULTS

The nausea scores at 15 min were statistically significantly different between the groups (p = 0.00). The postoperative nausea scores improved in 20 (43.5%) subjects in the placebo group, 38 (82.6%) subjects in the lavender group, 22 (47.8%) subjects in the rose group and 30 (65.2%) subjects in the ginger group (p = 0.00). There were statistically significant differences between the groups with regard to the vomiting and antiemetic drug requirements (p = 0.00).

CONCLUSION

The aromatherapy can be used as an alternative or complementary method for managing PONV. Specifically, the ginger and lavender essential oils were superior to the rose oil and pure water for the aromatherapy treatments. However, further studies with larger sample sizes are necessary to confirm these results.

Effects of Lavender Tea on Fatigue, Depression, and Maternal-Infant Attachment in Sleep-Disturbed Postnatal Women

BACKGROUND

Lavender inhalation aromatherapy is widely believed to impart a hypnotic effect, act as a mood stabilizer, and enhance the positive feelings of mothers toward their infants. However, research into these and other potential therapeutic effects of lavender tea has been limited.

AIMS

This study was conducted in Taiwan to evaluate the effectiveness of lavender tea in relieving sleep quality, fatigue, and depression; and in improving maternal-infant attachment during the early postpartum period.

METHODS

A total of 80 Taiwanese postnatal women with poor sleep quality (Postpartum Sleep Quality Scale; PSQS score ≥16) and with no history of allergy to herbal teas, foods, or medicines were assigned systematically to either the experimental group (n = 40) or the control group (n = 40). The participants in the experimental group were instructed to drink one cup of lavender tea after spending time to appreciate and smell the aroma each day for a period of 2 weeks, whereas their control group peers received regular postpartum care only. The PSQS, Edinburgh Postnatal Depression Scale, Postpartum Fatigue Scale, and Postpartum Bonding Questionnaire were used to assess outcomes.

RESULTS

ANCOVA analyses using education level and pretest scores as covariates showed that experimental group participants perceived less fatigue (F = 6.281, p = .014) and depression (F = 4.731, p = .033) and showed greater bonding with their infant (F = 4.022, p = .049) compared with the control group. However, the scores for all four instruments were similar for both groups at the 4-week posttest, suggesting that the positive effects of lavender tea were limited to the immediate term.

LINKING EVIDENCE TO ACTION

Healthcare researchers assume accountability for integrating research results into clinical practice. The findings in this study can gain greater attention among healthcare practitioners and encourage the correct and positive use of herbal therapy in postpartum health care.
