Granisetron Use, Blood Pressure, and Nausea and Vomiting During Cesarean Delivery Under Spinal Anesthesia

This study will observe 80 adults having a cesarean delivery under spinal anesthesia at Kayseri City Hospital. It will compare patients who receive granisetron as part of routine care to prevent nausea and vomiting with patients who do not receive preventive anti-nausea medicine. Granisetron use is decided by the treating anesthesiologist, not assigned by the study. Patients in the granisetron group receive the medicine within 5 minutes before or after spinal anesthesia. The main measurement is the total dose of ephedrine used during the operation. Ephedrine is a medicine used to treat low blood pressure. The study will also record low blood pressure at scheduled measurement points and nausea and vomiting during the operation. Patient enrollment is planned from October 15 to December 15, 2026.

RCT of Olanzapine for Control of CIV in Children Receiving Highly Emetogenic Chemotherapy

Chemotherapy-induced nausea and vomiting (CINV) are among the most bothersome symptoms during cancer treatment according to children and their parents. Most children receiving highly emetogenic chemotherapy (HEC), including those receiving hematopoietic stem cell transplant (HSCT) conditioning, experience CIV despite receiving antiemetic prophylaxis. Olanzapine improves CINV control in adult cancer patients, has a track record of safe use in children with psychiatric illness, does not interact with chemotherapy and is inexpensive. We hypothesize that the addition of olanzapine to standard antiemetics will improve chemotherapy-induced vomiting (CIV) control in children receiving highly emetogenic chemotherapy

Participants will receive foot reflexology in addition to routine postoperative care, and outcomes will be assessed using appropriate measures before and after the intervention.

A Clinical Trial to Evaluate the Effects of a Supplement on Symptoms Associated With Liver and Digestive Health

This study will evaluate the effects of Edenboost Alpha Cleanse, a dietary supplement, on symptoms associated with liver and digestive health. The study is a single-arm, open-label trial in which all 40 enrolled participants will use the test product daily for 12 weeks. Participants will complete questionnaires at Baseline, Week 4, Week 8, and Week 12, and will undergo blood testing (hepatic function panel) at Baseline and Week 12. Primary outcomes focus on changes in liver function biomarkers, while secondary outcomes capture participants' self-reported experiences of energy levels, abdominal bloating, abdominal pain, fatigue, and nausea.

Broadening Antiemetics Research by Comparing the Effectiveness of Fosaprepitant and Metoclopramide

The study team proposes a double-blind, comparative effectiveness, randomized controlled trial (RCT) to address the following goal: to determine the relative efficacy and adverse event profile of fosaprepitant compared to the standard of care antiemetic metoclopramide. Fosaprepitant and its active metabolite aprepitant are a relatively new class of antiemetic that exclusively acts in the central nervous system by blocking neurokinin (NK-1) which is a key signaling molecule in the centrally mediated aspects of the vomiting reflex. Currently, fosaprepitant and aprepitant both have only two United Stated Food and Drug Administration (USFDA) approved indications for nausea and vomiting: chemotherapy-induced and postoperative. Neurokinin inhibitors are highly effective and generally well-tolerated. Therefore, this class of medication may be a more appropriate medication for the millions of patients with nausea and vomiting that seek care in emergency departments (EDs). Intravenous fosaprepitant is converted to the active metabolite aprepitant on the order of minutes and is significantly cheaper to procure at this time.

Marginal Ulcer Healing With Low-Thermal Argon Plasma Endoscopic Treatment

The objective of the study is to investigate the treatment of marginal ulcers with Low Thermal plasma in an endoscopic setting. By a treatment of the ulcerated areas with argon plasma with low power settings (\~ 1 W) we hypothesize that the size of the ulcers will shrink, and the healing is accelerated compared to standard of care alone. Patients will benefit from this minimally invasive approach compared to a much more invasive surgical approach that comes with higher risks and hospital stay length time. From a societal and scientific perspective, this study aims to extend the well-documented clinical benefits of plasma technology - from external wound healing to internal ulcer treatment - within an endoscopic framework. The success of this study could pave the way for broader applications of LTP in the treatment of other endoscopically accessible conditions such as peptic ulcers, duodenal ulcers and esophageal ulcers. This advancement has the potential not only to improve patient outcomes through less invasive methods, but also to position LTP as a cornerstone in the future of gastroenterological wound management strategies.

Use of inhaled essential oils to reduce the symptoms of pain or nausea, enabling a patient to have increase participation with PT or OT, thereby minimizing hospitalization-related risks and potentially reducing the length of stay in the hospital.

Antiemetic Fosaprepitant To Remedy Nausea and Vomiting

The study team proposes a randomized, double-blind, RCT to address the following goal: to determine the relative efficacy and adverse event profile of fosaprepitant compared to the standard of care antiemetic ondansetron. Fosaprepitant and its active metabolite aprepitant are a relatively new class of antiemetic that exclusively acts in the central nervous system by blocking neurokinin (NK-1) which is a key signaling molecule in the centrally mediated aspects of the vomiting reflex. Currently, fosaprepitant and aprepitant both have only two United Stated Food and Drug Administration (USFDA) approved indications for nausea and vomiting: chemotherapy-induced and postoperative. Neurokinin inhibitors are highly effective and generally well-tolerated. Therefore, this class of medication may be a more appropriate medication for the millions of patients with nausea and vomiting that seek care in EDs. Intravenous fosaprepitant is converted to the active metabolite aprepitant on the order of minutes and is significantly cheaper to procure at this time. The outcome for the efficacy analysis will be no need for additional medication to treat nausea and vomiting within 2 hours of investigational medication administration. The primary outcome for the tolerability analysis will be the development of any new symptom within 2 hours of medication administration.

Box Breathing for Anxiety, Pain and Nausea in ERCP Patients

This study aims to evaluate the effects of a non-pharmacological breathing technique, known as box breathing, on anxiety, pain, and nausea in adult patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). ERCP is an invasive endoscopic procedure that may cause significant physical and psychological discomfort, including increased anxiety, pain, and nausea. Participants are randomly assigned to either an intervention group receiving standard care plus box breathing training or a control group receiving standard care alone. The box breathing technique consists of four equal phases of breathing (inhale, hold, exhale, hold), each lasting four seconds. Anxiety, pain, and nausea levels are assessed before ERCP and within the first 24 hours after the procedure. The results of this study may contribute to improving patient comfort and supporting the use of simple, nurse-led interventions in clinical practice.

Chronic Nausea and Vomiting in Patients With Normal Gastric Emptying Using the Enterra® Therapy System (NAVIGATE)

The purpose of this research study is to determine if the Enterra® Therapy System can decrease nausea and vomiting symptoms and improve the quality of life for patients with chronic nausea, with or without vomiting, that have normal gastric emptying.

Subcutaneous Route and Pharmacology of Metoclopramide

Subcutaneous (SC) route has become a standard of care of many drugs administration in palliative medicine. A preliminary study showed that, although it was widely adopted among palliative care practitioners for routinely prescribed medications, standards of proof are still lacking for many molecules. Among them, metoclopramide is a largely employed drug for nausea and vomiting treatment, particularly in palliative care and oncology. Therefore, the investigator aim to study absorption and efficacy of subcutaneous administration of metoclopramide.

Effect of Antiemetic Timing on Nausea Severity and Patient Comfort in the Emergency Department

Nausea is a common symptom among patients presenting to the emergency department and can negatively affect patient comfort and clinical outcomes. The timing of antiemetic administration may play a critical role in symptom control; however, evidence regarding the optimal timing remains limited. This multicenter interventional study aims to evaluate the effect of early versus delayed antiemetic administration on nausea severity and patient comfort in adult emergency department patients. Participants will be assigned to receive antiemetic treatment either within the first 30 minutes after triage or after 30 minutes. Nausea severity will be assessed using a numeric rating scale, and patient comfort will be evaluated at predefined time points. The findings of this study are expected to contribute to improving symptom management and optimizing clinical practices in emergency care settings.

Olanzapine Plus Metoclopramide for the Prevention of Opioid-Induced Nausea and Vomiting

The goal of this clinical trial is to evaluate the efficacy and safety of olanzapine plus metoclopramide in preventing opioid-induced nausea and vomiting (OINV) in adult patients with advanced cancer who are initiating strong opioid therapy. The main questions it aims to answer are: (1) Does the combination of olanzapine and metoclopramide reduce the incidence of OINV? (2)What adverse events do participants experience when taking the combination of olanzapine and metoclopramide? Researchers will compare the olanzapine-metoclopramide combination to a no prophylactic treatment control group to determine whether the combination is effective in preventing OINV. Participants will: Take olanzapine (2.5 mg/day ) and metoclopramide (10 mg three times daily) or receive no prophylaxis for 7 days; Through follow-up, nausea, vomiting, the time of the first attack of nausea and vomiting, the duration of nausea and vomiting, the use of strong opioids and adverse events were evaluated and recorded, as well as the pain score (using NRS) and quality of life (EQ-5D-5L) of the patients were evaluated at baseline and on day 7.

The Effect of a Protective Oral Care Protocol Using Peppermint Oil Mouthwash

Hematologic malignancies are the fifth most common type of cancer in the world. Patients with hematologic malignancies receive long-term and exhausting treatments such as chemotherapy, radiotherapy, hematopoietic stem cell transplantation and supportive therapies. Chemotherapy-induced nausea and vomiting has a significant impact on the daily lives of patients and causes physiological effects such as anorexia, malnutrition, weight loss, dehydration and electrolyte imbalance. It also has a negative impact on activities of daily living and psychological status, and may lead to poor adherence to chemotherapy regimens, refusal of chemotherapy or discontinuation of treatment. Oral mucosa is one of the areas most affected by the cytotoxic damage of chemotherapy. Disruption of the oral mucosa causes nausea, vomiting and feeding problems. Patients resort to non-drug approaches to manage these problems. It is important that these non-pharmacologic approaches are supported and controlled by reliable and evidence-based studies in order to prevent adverse effects on patient outcomes. In the literature, it has been determined that peppermint oil has antiemetic, antiseptic, anti-inflammatory, analgesic, antiseptic, antioxidant, antiviral, antifungal and spasmolytic effects, protects the integrity of the oral mucosa and has positive effects on nausea-vomiting and anorexia. In this context, the aim of the study was to investigate the effect of a preventive oral care protocol with peppermint oil mouthwash on chemotherapy-induced nausea, vomiting and appetite in patients with hematologic malignancy. Research Hypotheses H01: The protective oral care protocol applied with peppermint oil in patients with hematological malignancies has no effect on the development of chemotherapy-induced nausea and vomiting. H02: The protective oral care protocol applied with peppermint oil in patients with hematological malignancies has no effect on the severity of chemotherapy-induced nausea and vomiting. H03: The protective oral care protocol applied with peppermint oil in patients with hematological malignancies has no effect on the development of chemotherapy-induced anorexia. H04: The protective oral care protocol applied with peppermint oil in patients with hematological malignancies has no effect on the severity of chemotherapy-induced anorexia. Methods: The type of study is a single-blind randomized controlled experimental study. The research will be conducted between September 10, 2025, and April 10, 2026, with patients admitted to the hematology clinic of a university hospital for chemotherapy treatment. The study will be conducted with a total of 72 people who will be randomly assigned to the intervention (n=36) and control groups (n=36) by stratified and block randomization method. Patients who are 18 years of age or older, have hematologic malignancy, with a history of at least one chemotherapy cycle, and scheduled to receive chemotherapy with high or moderate emetogenic risk agents, do not have oral mucositis before chemotherapy, do not have metastasis, are literate and volunteer to participate in the study will be included in the study. Research data will be collected using the "Patient Introduction Form", "Rhodes Nausea-Vomiting and Retching Index", "Oral Assessment Guide", "Appetite Assessment Chart \[(Visual Analog Scale (VAS)\]", "Peppermint Oil Protective Oral Care Protocol", "Food Intake Record Form", "Allergic Reaction Monitoring Form" and "Patient Monitoring Form and Antiemetic Record Chart". In addition to the routine protective oral care (saline solution mouthwash and/or sodium bicarbonate mouthwash) in the clinic, "Peppermint Oil Protective Oral Care Protocol" will be applied to the intervention group for 6 days from the start of chemotherapy treatment. Patients will receive mouthwash prepared with 1 ml of peppermint oil and 50 ml of prepared drinking water 3 times a day. Patients in the intervention group will be monitored for 6 days by evaluating oral assessment, development of oral mucositis, appetite follow-up and compliance with mouthwash. The development of allergy due to the use of peppermint oil in each mouthwash application will be evaluated. The control group will not receive any oral care intervention by the researcher and will receive routine preventive oral care in the clinic. In the evaluation of the data, descriptive statistics, Chi-square / Fisher's Exact test will be used for the relationship between categorical variables, Mann Whitney U test, Wilcoxon test, Kruskal-Wallis H test will be used for the relationship between continuous variables in groups that do not show normal distribution; one-way analysis of variance / repeated measures analysis of variance, t test for dependent and independent groups will be used in groups with normal distribution. Correlation analysis and regression analysis will be used to examine the relationship between variables.
