Brief summary

Cancer is a major cause of death and disability worldwide and in South Asian countries. Cancer treatment options include chemotherapy, radiation therapy, surgery, and adjuvant therapy (Additional treatments after primary cancer treatment such as surgery, radiation, or chemotherapy are used to lower the chance of cancer recurrence or remove any remaining cancer cells). Chemotherapy poses serious adverse effects, including fatigue, hair loss, skin irritation, loss of appetite, change in bowel habits, weakened immune system, dry mouth, peripheral neuropathy, nausea and vomiting. Chemotherapy-induced nausea and vomiting cause fluid-electrolyte imbalance, dehydration, weight loss and physiological consequences due to inadequate medication absorption or compromised kidney clearance. Although anti-emetic drugs are given to reduce CINV but these drugs pose some serious adverse effects including heartburn, insomnia, headache, dizziness, constipation/diarrhea, loss of muscle control, pharyngeal itching, dry mouth and also increases economic burden on the patient and his/her family. The limited and hazardous side effects of these medications have led to a shift towards non-pharmacological and home remedies. Using natural remedies is a simple and low-risk measure in this regard. This study aims to evaluate the effects of peppermint oil inhalation on the intensity and frequency of Chemotherapy induced acute nausea and vomiting among cancer patients undergoing chemotherapy. A randomized controlled trial will be conducted using non-probability convenience sampling, followed by random assignment to intervention and control groups. The target population comprises patients receiving chemotherapy at the outpatient oncology department of Jinnah Hospital, Lahore. A total of 106 patients will be enrolled. The intervention group will receive peppermint oil inhalation, while the control group will receive a placebo. Descriptive statistics (frequency, percentage, mean, and standard deviation) will be used to summarize participant's characteristics. Chi-square test will be applied to compare demographic variables (e.g., age, gender, marital status, education, occupation, and RINV categories) between groups. An independent t-test will be used to compare the mean RINV scores post-intervention between intervention and control group. A p-value of \<0.05 will be considered statistically significant. It is anticipated that peppermint oil inhalation will significantly reduce the severity and frequency of Chemotherapy induced acute nausea and vomiting. If effective, this complementary intervention could offer a low-cost, safe alternative to supplement standard anti-emetic therapies, potentially easing the financial and physiological burden associated with pharmacological treatments.

Interventions

DIETARY_SUPPLEMENTPepppermint oil inhalation

Participants in the experimental group will inhale five drops of 100% pure peppermint essential oil placed on a cotton ball inside a container for ten minutes before each chemotherapy session and every two hours during the chemotherapy infusion.

DIETARY_SUPPLEMENTPlacebo

The control group will follow the same procedure using five drops of distilled water placed on a cotton ball inside a container for ten minutes before each chemotherapy session and every two hours during the infusion

Design outcomes

Primary

MeasureTime frameDescription
Effect of Peppermint Oil Inhalation on the Intensity and Frequency of Acute Nausea and Vomiting Measured by RINV ScaleWithin 24 hours after chemotherapy (acute phase)The primary outcome is the change in the intensity and frequency of acute nausea and vomiting, assessed by the Rhodes Index of Nausea, Vomiting, and Retching (RINV) Scale, within 24 hours following chemotherapy. Comparison of mean RINV scores will be made between the experimental (peppermint oil inhalation) group and the control group.
