Filter by:This study will assess the efficacy of a single dose of intravenous (IV) fosaprepitant (MK-0517, EMEND® IV) as salvage therapy when added to a 5-hydroxytryptamine receptor 3 antagonist (5-HT3 RA) and dexamethasone for the prevention of chemotherapy-induced vomiting (CIV) in participants who experienced CIV in the first cycle of moderately emetic chemotherapy (MEC). The primary hypothesis is that there will be no vomiting and no retching in at least 20% of participants during the second cycle of MEC in participants who previously experienced vomiting during the first cycle of MEC.
The primary objective of this study is to evaluate the efficacy of a single palonosetron IV dose compared to a single ondansetron IV dose in the prevention of postoperative nausea and vomiting through 24 hours after surgery in children aged from neonates up to less than 17 years undergoing elective surgical procedures requiring general intravenous anesthesia. The secondary objective is to evaluate the safety and tolerability of IV palonosetron in pediatric patients.
Postoperative nausea and vomiting after outpatient surgery are significant sources of patient dissatisfaction. The prevention of postoperative nausea and vomiting (PONV) should be equally as important as prevention of pain because both are large sources of patient dissatisfaction and can necessitate admission after routine outpatient procedures. None of the currently available pharmacological interventions are able to totally abolish PONV. The use of electroacustimulation is a useful adjunct in prevention of PONV, but has yet to be studied when the patient takes the device home with them after leaving an outpatient facility.
Ketamine added to intravenous patient-controlled analgesia may be effective on prevention of postoperative nausea and vomiting by reducing opioid requirement after surgery.
Every year, more than 5 million patients in the US experience postoperative nausea and/or vomiting (PONV) and in the ambulatory setting post-discharge nausea and/or vomiting (PDNV) is the most common cause for unanticipated hospital re-admissions. Similarly, millions of patients suffer from chemotherapy induced nausea and/or vomiting (CINV), and one out of five patients discontinues chemotherapy for this reason. Thus, the control of nausea and vomiting remains a major health concern for the investigators society. The investigatorsoverall goal is to further the understanding of nausea and vomiting and optimize antiemetic selection in order to facilitate individualized patient care. Unfortunately, current antiemetics reduce the incidence of nausea by only about one third. As a result, antiemetics are often combined, exposing patients to adverse events and drug interactions without evidence for the most effective combination. Moreover, it remains unclear why such a large amount of inter-individual variability exists in antiemetic responsiveness. 5HT3, NK1, and GABA receptors are targets for some of the most commonly prescribed anti-emetics. Furthermore, these receptors have many known genetic polymorphisms, including several linked to incidence of nausea and vomiting. Thus pharmacogenomic variation may in part explain interindividual differences in treatment responses and will be tested in this proposal. Leveraging the established infrastructure of the UCSF Clinical and Translational Science Institute, and the support of 6 patient recruitment sites, the investigators will enroll 1280 high risk patients to three oral interventions with distinct mechanisms of action for nausea and vomiting. Investigating nausea and vomiting in ambulatory surgical patients is an excellent model for this trial owing to a high incidence, short observational period, and the ability to standardize and control potentially confounding variables. In this proposal, 100% of patients will receive a single intraoperative dose of 4 mg ondansetron, which is similar to the 80% of patients who receive prophylaxis in common practice. Using a factorial design, these patients will be randomized to receive one out of eight possible combinations of the three interventions (ondansetron, aprepitant, lorazepam) versus placebo (ond+aprep+lora, ond+aprep, ond+lora, aprep+lora, ond, aprep, lora, or placebo). Thus, in this proposal 87.5% (7 out of 8 patients) will have antiemetic coverage for the postdischarge period, which is considerably higher than in common practice, where only 4% of patients have antiemetic coverage after discharge. The primary endpoint will be the prevention of nausea and vomiting within 48 hours after ambulatory surgery. The advantage of the factorial trial design is its high efficiency to systematically investigate multiple interventions while allowing us to test for potential interactions. It is also an ideal format for the simultaneous assessment of pharmacogenomic interactions of antiemetics in this proposal. To this end, the investigators will collect DNA samples and take advantage of the unique opportunity to investigate the effects of variation in candidate receptor genes in the context of the three treatment interventions for PDNV. This approach may in part explain inter-individual differences in drug efficacy and allow for future screening of at-risk patients. Specifically, the investigators will be assessing single nucleotide polymorphisms (SNPs) and copy number variants (CNVs) of targeted receptors for the antiemetics tested. Aim 1: To determine efficacy of three interventions for the prevention of PDNV. Hypothesis 1.1: Each intervention reduces the incidence of PDNV. Hypothesis 1.2: Efficacy of all interventions is independent so that efficacy of a combination can be derived from the efficacy of the individual interventions. Aim 2: To determine if drug response for anti-emetics is dependent upon genetic variance. Hypothesis 2: Efficacy of ondansetron, aprepitant and lorazepam to reduce PDNV differs with 5HT3, NK1, and GABA receptor gene variation, respectively.
Postoperative nausea and vomiting (PONV) remain a significant challenge in our practice. However, pharmaceutical prophylaxis can confer unpleasant adverse effects. It would therefore be appropriate to consider the use of non-pharmacological methods in preventing PONV. Acupuncture and acupressure are reported to be effective preventive treatment for PONV, and the adverse effects are minimal. Consequently, the aim of the study is to implement acupressure in our anaesthetic department procedures. A reduction of the use of antiemetics will be a parameter on the effectiveness of acupressure. The study will focus on acupressure as a supplement to the ordinary prophylactic treatment of PONV in adults undergoing orthopaedic and general surgery, and adults and children undergoing ear, nose, throat surgery. The primary endpoints are the quantities of antiemetics used before (baseline) and during the implementation period. The study will be conducted from January to December 2011.
- This randomized controlled three arm study compares the effects of a yoga intervention with jacobsons progressive muscle relaxation training and only standard of care in chemotherapy naive cancer patients. - This study will also assess the neurophysiological correlates of nausea and vomiting and assess if effects of intervention on nausea and vomiting outcomes are mediated by changes in gastric motility (electrogastrogram) or stress arousal (cardiac autonomic function and sympathetic skin response) or self reported anxiety.
The purpose of this study is to characterize the accompanying symptoms, evaluation and management of patients with chronic vestibular dysfunction presenting with nausea and vomiting.
The purpose of this study is to evaluate the safety and immunogenicity of Rotavin-M1 produced by the Center for Research and Production of Vaccines and Biologicals (POLYVAC) in infants in Vietnam. In addition, we evaluate different dosages and schedules to determine the best regimen to test in a clinical trial.
NETU-10-29 is a clinical study assessing safety of netupitant and palonosetron, two antiemetic drugs, both given with oral dexamethasone. The objective of the study is to evaluate if netupitant and palonosetron are safe when administered to prevent nausea and vomiting after administration of repeated cycles of chemotherapy.
