Filter by:This randomized phase III trial studies how well olanzapine with or without fosaprepitant work in preventing chemotherapy induced nausea and vomiting in cancer patients receiving chemotherapy that causes vomiting. Olanzapine and fosaprepitant dimeglumine may help control nausea and vomiting in patients during chemotherapy. Olanzapine is usually given in combination with other drugs, including fosaprepitant dimeglumine. It is not yet known if olanzapine when given with other drugs, is still effective without using fosaprepitant dimeglumine for controlling nausea and vomiting.
Aromatherapy has been proven to be effective for treating patients with postoperative nausea and vomiting (PONV) after surgery, but few studies analyze its effect on preventing PONV. Most studies use aromatherapy once patients become nauseous, but this study will address a gap in the literature with relation to the effect of aromatherapy in the prevention of PONV.
Operations of oral maxillofacial surgery cause the blood escape into stomach and trachea. Therefore, throat packing is applied. Endotracheal tube cuff is not protective from aspiration. While packing is preventing blood leakage, it may cause postoperative pain due to the pressure. Packing placed between oropharynx and hypopharynx before surgery to prevent leakage to stomach and trachea. The aim of this study is to compare the efficacy of two packing types in throat pain.
To evaluate the safety and efficacy of aprepitant combined with ondansetron and dexamethasone to prevent nausea and vomiting induced by Intensity-modulated Radiotherapy (IMRT) cisplatin-chemotherapy regimen in locally advanced squamous cell carcinoma of head and neck
Chemotherapy induced nausea and vomiting (CINV) is a common adverse effect in treatment of cancer, which influences the quality of life and adherence to treatment of patients and leads to dehydration, malnutrition and even death. Prevention and relieving the CINV is an important step to ensure the conduction of chemotherapy. Mechanism of CINV remains to be obscure, while most studies showed that it is mainly related to the following respects: ⑴ Chemotherapeutic agents stimulate gastrointestinal tract, which induces the release of neurotransmitters by chromaffin cells. Neurotransmitters bind to corresponding receptors, and then results in vomiting by stimulating the vomiting center; ⑵ Chemotherapeutic agents and the metabolites of them activate chemoreceptors directly, which causes vomiting. ⑶ Feeling and mental factors irritate cerebral cortex pathway directly. There are studies suggested that 5- hydroxytryptamine (5-HT) was related to acute nausea and vomiting induced by chemotherapy, which means 5-HT receptor antagonist would be a effective medicine for acute CINV. In addition, there are researches proclaimed that neurokinin-1 (NK-1) receptor antagonist, aprepitant, is a potent agent to relieve CINV. Thus, correlative guidelines recommend regimens with 5-HT receptor antagonist, NK-1 receptor antagonist and glucocorticoid as the standard treatment for strongly emetic chemotherapy regimens. But the prevention of moderately emetic chemotherapy regimens remains to be a problem in clinical practice. Besides, there is no study to demonstrate differences of mechanisms between acute CINV and delayed CINV. Olanzapine inhibits kinds of neurotransmitters which cause CINV, it is why this medicine is effective in both acute and delayed CINV. It can also alleviate anxiety, improve sleep quality and relieve pain in patients with cancer. The most common adverse effects of olanzapine are lethargy, body mass increase, fatigue, dry mouth, constipation, hyperlipidemia and hyperglycemia. Among them, the most common one is lethargy, which can oppose insomnia and excitation caused by dexamethasone. In a word, olanzapine is an agent with mild adverse effects, it is worth to be generalized. But there are still problems to be resolved in the application of olanzapine in CINV: ⑴ Aprepitant is expensive and not covered in medical care in China, which limits the application in patients. ⑵There is no large clinical trial to confirm the efficacy and safety of olanzapine in Chinese populations. To explore these issues better, investigators intend to compare the regimen with olanzapine, dexamethasone and 5-HT receptor antagonists with the regimen with placebo, dexamethasone and 5-HT receptor antagonists about the efficacy and adverse events in treatment of CINV. Investigators aim to provide an available therapeutic options for CINV, improve the quality of life and prolong the survival of patients with lung cancer.
Postoperative nausea and vomiting (PONV) is commonly accompanied in patients undergoing surgery under general anesthesia. The patients undergoing laparoscopic gynecologic surgery have multiple risk factors for developing PONV such as female gender, nonsmoker, postoperative opioids, and laparoscopic surgery. Thus, it is important to prevent PONV in these patients.
This study evaluates the effects of essential oils on nausea, vomiting, and quality of life scores among pregnant women. Participants will receive either an essential oil roll-on product or a placebo product to apply to their temples and jaw line daily for 6 days.
This study compares the intraoperative opioid free anesthesia approach in laparoscopic bariatric surgery to a conventional opioid- based anesthesia. Half of participants will receive opioid free anesthesia with dexmedetomidine, lidocaine and ketamine while the other half will receive opioid based anesthesia with fentanyl, remi-fentanyl and ketamine
The Researchers overall goal is to evaluate the benefit and utility of preemptive genotypic data to guide post-operative nausea and vomiting treatment in the bariatric surgical population. The hypothesis is that using genotypic variation in CYP2D6 to select the appropriate 5HT3 serotonin receptor antagonist to treat PONV will decrease rates of PONV in the bariatric surgical population.
Prospective observational study to analyse the association of non-genetic variables as well as genetic variants of candidate genes with the incidence of postoperative nausea and vomiting (PONV).
