Active clinical trials for "Nausea"

The investigators investigate the association between the administration of glycyrrhizin during induction of general anesthesia and the occurrence of postoperative nausea and vomiting (PONV) in patients undergo breast surgery

This is a longitudinal, one arm, prospective phase II study, designed to evaluate the efficacy of Olanzapine Netupitant and Palonosetron in the controll of nausea and vomiting induced by highly emetogenic chemotherapy.

Postoperative nausea/vomiting (PONV) is a common problem following surgery and anesthesia. There are risk factors that increase the incidence of PONV that are related to the patient, to the surgical procedure or to the anesthetic agents. At the subjective level PONV is described as worse and more feared than postoperative pain by many patients. At the objective level it increases the length of stay in the recovery room, it results in unplanned hospital admission and Emergency Room visits, and therefore increased cost of care. A lot of research work has been done to identify pharmacological agents to prevent and treat PONV. The higher the risk of a patient the higher number of these drugs are combined for prophylaxis. However, these drugs have significant side effects of their own. Much less attention has been paid to potential non-pharmacological PONV prevention options. The purpose of our study is to investigate the putative role of the natural stimulation of normal gastrointestinal function via the Pavlovian reflex. We seek to find a natural method with no side effects to improve PONV prophylaxis in patients with risk factors for that postoperative complication.

The purpose of this study was to evaluate the effectiveness of additional ramosetron injection for controlling late postoperative nausea and vomiting (PONV) after breast surgery in high risk PONV patients. The investigators compared PONV amomng 3 groups- group C: no additional ramosteron, group B: two additional ramosteron doses at 12 hour interval, group M: two additional ramosetron doses mix to the intraveonus patient controlled analgesia.

The purpose of this study is to compare the effectiveness of acupressure point P6 stimulation versus intravenous ondansetron plus metoclopramide versus no antiemetic prophylaxis during elective cesarean section under regional anesthesia.

Effect of intravenous versus intra-peritoneal dexamethasone on the incidence of postoperative nausea and vomiting following Laparoscopic gynecological surgeries.

BACKGROUND: Palonosetron is a second generation serotonin antagonist usually used in a fixed dose of 75 mcg for the prophylaxis of postoperative nausea and vomiting. Although there are a few trials evaluating bodyweight-adjusted doses of palonosetron, the ideal dose for obese patients has not yet been investigated. The aim of this study is to evaluate if the use of bodyweight-adjusted doses of palonosetron (1mcg / kg) is more effective than a fixed dose (75mcg) on preventing postoperative nausea and vomiting in female patients with a body mass index equal to or above 30 kg /m2 whom have undergone breast surgery METHODS: A prospective, randomized double-blind trial will be conducted at the National Cancer Institute (INCA - HCIII), in Rio de Janeiro, Brazil. Eligible patients are female aged between 18-70 years of age with an ASA physical status of one to three, with body mass index equal to or greater than 30 kg / m2, scheduled to undergo elective breast surgery. Forty patients will be randomized to receive a fix dose of 75 μg of palonosetron (group I - GI) and 40 patients will receive a bodyweight-adjusted dose of 1mcg/kg of palonosetron (group II - GII). Patients will be assessed over 3 time periods: 0-6 h, 6-26 h and 24-48 h after surgery. After discharge, all patients will be contacted by telephone at regular intervals to record the episodes of nausea and vomiting as well as analgesic and antiemetic requirements. The primary outcome measure will include the number of emetic episodes, the incidence of nausea, the need for rescue antiemetics and the analgesic requirement over 48h. The secondary outcome will be to evaluate the frequency of polymorphism of the 5-HT3 receptors and their correlation with the antiemetic effect and adverse effects.

Opioid-based intravenous patient-controlled analgesia (IV-PCA) offers excellent pain control, however, its use inevitably increases the incidence of postoperative nausea and vomiting (PONV). Ramosetron and palonosetron are commonly used 5-HT3 antagonists for the prevention and treatment of PONV. It is not clear which one has superior antiemetic efficacy for the prevention of PONV in patients using opioid-based IV-PCA. The antiemetic efficacy of 5HT3 antagonists may be influenced by polymorphism of ABCB1, a drug-transporter gene. This study evaluates relative antiemetic efficacy of ramosetron and palonosetron in patients using IV-PCA after spinal surgery and impact of ABCB1 polymorphism on the antiemetic efficacy of the ramosetron and palonosetron. The incidence and intensity of PONV during postoperative 48 h will be assessed. ABCB1 polymorphisms 3435C>T and 2677G>T/A will be evaluated in all patients.

Postoperative nausea and vomiting is one of most common complications after general anesthesia. Female sex, history of postoperative nausea and vomiting, motion sickness, non smoker status, opioid administration are known as risk factors for developing postoperative nausea and vomiting. It has been suggest that antagonism of residual neuromuscular block with a mixture of neostigmine and atropine at the end of the surgery increases the risk of postoperative nausea and vomiting. Sugammadex is a very safe drug with almost no serious adverse effects. The known adverse effects include slight coughing, movement, an altered taste sensation in the mouth, transient prolongation of the QT interval, hypersensitivity, and a short term prolongation of the activated partial thromboplastin time. The aim of this study was to compare the sugammadex versus neostigmine plus atropine for reversal of rocuronium induced neuromuscular blockade in terms of incidence of postoperative nausea and vomiting.

This study was aimed to evaluate efficacy and tolerability of thalidomide in improving prevention of chemotherapy-induced delayed nausea and vomiting in chemotherapy-naive patients after highly emetogenic chemotherapy.
