About this study
Official title: The Effect of Peppermint Oil on Nausea, Vomiting and Retching in Cancer Patients Undergoing Chemotherapy: A Randomized Controlled Trial
The aim of this study was to determine the effect of peppermint oil upon incidence of nausea, vomiting and retching, nause severity, and the usage amount of antiemetics in cancer patients undergoing chemotherapy.
Read the detailed description
Nausea, vomiting and retching symptoms are among the most common adverse effects of chemotherapy and are defined with expressions like "the biggest problem including pain" by patients. Chemotherapy-induced nausea and vomiting (CINV)' is reported leads to fluid-electrolyte imbalance, dehydration, loss of weight, physiological effects caused by poor drug absorption or decreased elimination from kidneys as well as negative effects in one's social life, work-life, activities of daily life and psychological status. Also, nausea-vomiting may cause some patients to refuse chemotherapy or to discontinue the treatment. Inadequate control of CINV leads patients to integrative health practices.
The study was realized as a randomized controlled study in order to explore the effect of use of 3% peppermint oil applied on lips three times a day during the five days following chemotherapy upon incidence nausea, vomiting, and retching, nausea severity and quantity use of antiemetics in cancer patients undergoing chemotherapy.The study was initiated on the 10.09.2017 and in this study were interviewed with 250 patients. 90 patients that met inclusion criteria were contacted. The study was completed with 36 intervention patients and with 44 control patients (See Fig. 1). For determine to sample size, while patients were being allocated to the study groups, post hoc power analysis was periodically done with the data obtained. The sample size for this study was calculated using the MedCalc (32-bit). The process continued until the necessary sample size was reached. According to power analysis, α = 0.05 and β =0.20, and the power of the study was 99.9%.
Randomization In order to provide randomization was preferred ballot method. As a result of the ballot, the first patient who inclusion criteria of study was allocated to the intervention group while the next one to the control group. After participant enrollment, patients were assigned to the two groups in a 1:1 ratio according to this rule. Because of it is not known whether nausea/vomiting experience of patients who first time chemotherapy receiving, study groups included patients receiving two or more chemotherapy.
Interventions 2.4.1. The control group The control group underwent only the routine treatment. The patients in the control group, Patient Watch Chart, Patient Nausea Severity Follow-up Form, and INVR, marked by patients and They were returned the duly completed these forms to the researcher when they came to hospital for the next chemotherapy treatment. Patient Watch Chart, and INVR skala of patients who illiterate were filled in by the pollster, according to expression of patient. In order to fill in Patient Watch Chart, and INVR phone interviews were made twice a day (morning-evening) by the pollster and the participants at a suitable time determined together.
2.4.2. Intervention group The patients in the intervention group received routine medical treatment program and were asked to put one drop of peppermint oil upon lips following chemotherapy administration. Before peppermint oil application; the researcher theoretically and practically provided a training of 8-10 minutes about the use of peppermint oil and the patients were requested to apply this oil three times a day according to "Oil Practice Guide" (See Fig. 2) in the morning (09:00), at noon (15:00) and in the evening (21:00). The mobile phones of the participants were set to these hours and the alarm system continued in this manner for five days. The participants whose mobile phones were not set to these hours were called by the researcher in order to recall them of the protocol. Before peppermint oil application, Patient Opinion Form (pre-application) were asked to the participants and their answers were written down. Similarly; after peppermint oil application, same form (post-application) were asked and the answers were written down. Patient Watch Chart, Patient Nausea Severity Follow-up Form, and INVR, marked by patients and They were returned the duly completed these forms to the researcher when they came to hospital for the next chemotherapy treatment. Patient Watch Chart, and INVR skala of patients who illiterate were filled in by the pollster, according to expression of patient. In order to fill in Patient Watch Chart, and INVR phone interviews were made twice a day (morning-evening) by the pollster and the participants at a suitable time determined together.
Patients in the intervention and control groups were allowed to take standard antiemetic medications and other drugs taken for different medical problems during and after the day of peppermint oil application. As a part of standard antiemetic treatment; patients were given " in isotonic solution 5-HT3 receptor antagonists (palonosetron, granisetron (Kytril))+ steroids (dexamethazon (Decort)) + antihistaminic (Avil or Systral ampul) + Metpamid ampul" before chemotherapy.
Onzyd 8 mg (ondansetron) + metpamid tb. has been prescribed by oncologist, for able to use at patient's home.

The data were collected using a Patient Information Form, Rhodes Index of Nausea, Vomiting and Retching (INVR), Visual Analog Scale (VAS) Patient Nausea Severity Follow-up Form, Patient Watch Chart, and Oil Application Protocol. Besides, patients in the intervention group were questioned thoughts associated with peppermint oil application using individual in-depth interview method. Receives: Other: aromatherapy (peppermint oil) |
| control group | No intervention | The control group underwent only the routine treatment. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Patient Information Form
The form was consisted of 17 statements in order to explore patients' socio-demographic characteristics (age, sex, educational status, marital status, number of children, etc.), and diagnosis, treatment protocol, and complementary and integrative health practices used to cope with cancer and nausea-vomiting symptoms.
Measured: 1 day (first day)
Visual Analog Scale (VAS)- Nausea Severity
The scale (VAS) was used to accept patients to the study. VAS is composed of 10-cm (100 mm) line which at the left end by words "No nausea 0" and increased numbers indicated rising nause levels; at the right end "Severe nausea 10". The patient is asked to place a mark on the scale to indicate the level of intensity of his or her nausea. Distance of patient's mark to left end is measured with a ruler in millimeter and is accepted and written as score
Measured: 1 day (fist day)
Secondary outcomes (5)
Patient Watch Chart
The form was separately designed for the intervention and control groups after a thorough review of the relevant literature. Patient Watch Chart was designed to explore status of use of antiemetics prescribed only by physicians for the patients in the control group while in the intervention group, to explore status of use of antiemetics and status of peppermint oil.
Measured: 1-5 days
The Index of Nausea, Vomiting, and Retching- INVR
The index was developed by Rhodes V. and Mc Daniel R. (Rhodes \& Mc Daniel, 1999) in order to explore post chemotherapy nausea, vomiting, and retching frecuency and distresses that patients experience. The index is composed of 8 questions. Assign a numeric value to each response from 0, (the least amount of distress), to 4, (the most distress). Total symptom experience from nausea and vomiting is calculated by summing the patient's responses to each of the eight items on the Rhodes INV. The potential range of scores is from a low of 0 to a maximum of 32. Patients are required to fill in the form in the most suitable period of 12 hours that they decide. There are three subdimensions: symptoms experience, symptoms occurrence, and symptoms distress. In order to score the INVR; 1st, 3rd, 6th and 7th items should be reversed.
Measured: 1-5 days
Peppermint Oil Application Protocol
The guideline were prepared in line with expert opinion and literature in order to show stages and important oints of oil application and to make sure that the oil application would be carried out in the same manner by all the patients. The aromatherapy essential oil used was a mixture of English peppermint (Mentha piperita; 3%) and sweet almond oil (30 ml), Patients were informed of keeping the aromatic mixture in a closed and dark bottle, in a cool place and away from sunshine. The peppermint oil application was carried out according to Oil Practice Guide (See Fig. 2) by the patients in the intervention group.
Measured: 1-5 days
Patient Opinions Form of Peppermint Oil Application
The form included semi-structured questions designed in line with expert opinions and literature in order to identify opinions of the patients in the intervention group about the peppermint oil application (Muz \& Taşcı, 2017). The questions in the form were asked to the patients before and after peppermint oil application and patient opinions were voice-recorded or written down. Before peppermint oil application; the questions ("What do nausea and/or vomiting mean for you?, How do these symptoms influence your life?, Do you believe that the oil to be used will help lessen your symptoms?") were asked whereas after peppermint oil application; the questions ("Do you think that peppermint oil application has had effect upon nausea, vomiting, and retching symptoms?, How has peppermint oil application affected your daily life?, What are the easy and difficult sides of peppermint oil application?") were asked to explore patient views.
Measured: only 1st and 5th day
VAS-Patient Nausea Severity Follow-up Form
In order to assess severity of nausea experienced by patients after chemotherapy administration; VAS- Patient Nausea Severity Follow-up Form was developed by the researcher and marked by the patients in intervention group and control group. The form consists of VASs that marked two times a day -in the morning and in the evening- during five days (Zorba \& Özdemir, 2018; Arslan \& Özdemir, 2015). Marking and evaluation of the VAS's in the form were done according to the principles in the Visual Analogue Scale (VAS) - Severity of Nausea.
Measured: 1-5 days
