Filter by:Propofol and sevoflurane have different effects on heart rate variability. It has not yet been reported whether this difference in effect remains at recovery time after anesthesia and the difference is related to postoperative nausea and vomiting has not been studied. The aim of this study is observe whether propofol and sevoflurane have different effects on heart rate variability during recovery and the differences can predict the occurrence of postoperative nausea and vomiting.
The study has been designed as a prospective randomized clinical trial. Due to the use of a bispectral (BIS) monitor in the interventional arm, the study will not be blinded for the anesthetist. The total planned number of study subjects is 100. Patients will be randomly randomized upon arrival to the operating theatre (using the envelope method) into the interventional arm (BIS monitoring of the depth of general anesthesia), and into the control group (standard management of general anesthesia to minimum alveolar concentration (MAC) 1,0). The target values of the depth of general anesthesia according to BIS are between 40 and 60.
Nausea and vomiting after surgery are one of the complications that occur after general anesthesia, and the frequency is reported to range from 10% to 80% in the high-risk group. Several studies have introduced drugs and methods to prevent nausea and vomiting after surgery. Among them, midazolam administered before surgery is known to have anti-anxiolytic and sedative effects on the prevention of nausea and vomiting after surgery. It has also been reported to increase its effectiveness when administered with other antiemetic agents. The purpose of this study is to compare the effects of administration of combination with midazolam and different antiemetic agents on the prevention of postoperative nausea and vomiting in high-risk patients.
Postoperative nausea and vomiting (PONV) is a common complication after surgery. Patients undergoing orthognathic surgery are reported to have a high rate of PONV, especially those undergoing bimaxillary surgery. Activation of cholinergic system plays an important role in the development of PONV. Penehyclidine is an muscarinic antagonists which selectively block M1 and M3 receptors and is commonly used to decrease oral secretion. The investigators hypothesize that continuously administrated penehyclidine during perioperative period can reduce the incidence of PONV in patients undergoing bimaxillary surgery.
Chemotherapy-induced nausea and vomiting is a common side effect of cancer treatments, and dexamethasone offers a clear advantage over placebo for protection against chemotherapy-induced emesis in both acute and delayed phases. However, its side effects such as moderate to severe insomnia, hyperglycemia, dyspepsia, upper abdominal discomfort, irritability, increased appetite, weight gain and acne are gathering increasing concerns. Several clinical trials have shown that olanzapine plays an important role in treating delayed, refractory, breakthrough nausea and vomiting. Its side effects mainly include sedation and weight gaining. At present, the NCCN guidelines have recommended olanzapine-containing three-drug regimen for Highly Emetogenic Chemotherapy (HEC) and moderate emetic chemotherapy (MEC) to prevent vomiting, but its data in the Chinese population is limited. Hence, we initiated this prospective, multi-center, phase III study to validate the dexamethasone-free protocol: applying olanzapine to prevent CINV instead of dexamethasone.
Previous history of nausea and vomiting induced by prior chemotherapy still not included as predictive factor of postoperative nausea and vomiting, although has been demonstrated that has influence in postoperative outcome. The project aims to evaluate the efficacy of a simplified algorithm in prevention postoperative nausea and vomiting , with pacients with previous history of nausea and vomiting induced by prior chemotherapy, submitted to medium or large surgery.
Nausea and vomiting in pregnancy (NVP) is one of the most common symptoms of pregnancy affecting 50-85% of women during the first half of pregnancy. Maternal morbidity is common and includes psychological effects, financial burden, clinical complications from nutritional deficiencies, gastrointestinal trauma, and in rare cases, neurological damage. As the main means of alternative treatment, economical and easy to obtain; the clinical efficacy of acupuncture treatment of this disease has low level of evidence and needs to be reconfirmed. Doxylamine vitamin B6 sustained release tablets (Diclectin, combination of doxylamine succinate (10mg) and pyridoxine hydrochloride (10mg) are The American College of Obstetricians and Gynecologists recommends with Level A evidence the use of vitamin B6 in combination with doxylamine as first-line pharmacotherapy for treatment of NVP. The efficacy and safety of Diclectin has been confirmed in many years of research, but there is no evidence of high-level evidence-based medicine for the Chinese population. The purpose of this multicenter, randomized, double-blind, placebo-controlled trial was to investigate the efficacy and safety of acupuncture versus Diclectin in the treatment of NVP. We hypothesis that: (1)Sham acupuncture and Diclectin (Arm B) is more effective than sham acupuncture and placebo (Arm D); (2)Active acupuncture and placebo (Arm C) is more effective than sham acupuncture and placebo (Arm D); (3) There is no interaction (either synergistic or antagonistic effects) between the two interventions of active acupuncture and Diclectin in patients with NVP.
A comparative effectiveness research design was used. The sample size was calculated to 136 patients, who were randomized to an intervention group and a control group respectively. The patients were terminal ill patients enrolled to three in-bed hospices in Denmark and nausea and vomiting were measured using EORTC QlQ-c15-PAL (European Organisation for Research and Treatment of Cancer, Quality of Life Questionaire, core 15, Palliation)
This study evaluates the prevalence of delayed chemotherapy induced nausea in adult oncology patients in real clinical practice of day clinics.
Patients undergoing stem cell transplantation for the first time will be entered. Participants will be randomized to one of two study arms: Arm 1: intervention (routine care+ inhalation aromatherapy); Arm 2: Control (Routine care) Hypotheses: (1) Patients receiving inhalation aromatherapy will experience less severe nausea and less frequent vomiting episodes than those receiving only routine care; and (2) patients receiving inhalation aromatherapy will demonstrate lower anxiety levels just after AHSCT than those receiving only routine care.
