Post-operative nausea and vomiting are a leading cause of recovery room delays and low patient satisfaction. Complications such as suture line tension, wound hemorrhage and dehiscence, elevated intracranial pressure, pulmonary aspiration, dehydration, and electrolyte imbalance have been linked to nausea and vomiting. Many studies were done to explore the effects of propofol and dexmedetomidine on the incidence of post operative nausea and vomiting (PONV). In this study, we will compare propofol infusion to dexmedetomidine infusion on the incidence of PONV in patients undergoing ureteroscopic procedures under spinal anesthesia in the age group from 18 to 60 years with more than one risk factor for PONV (female, history of PONV, non-smoking).
PONV is the most common clinical presentation after surgical procedures beyond pain. A retrospective study of our center found that the postoperative incidence of LSG was 77.4%. PONV can not only cause postoperative discomfort, but also cause serious complications such as disturbance water and electrolyte balance, wound splitting, incisional hernia, and even residual gastric leakage and aspiration pneumonia, resulting in prolonged hospital stay and increased medical costs. Wrist and ankle acupuncture is a special kind of acupuncture therapy. Through subcutaneous stimulation, the electrical signal is fed back along the nerve fiber into the cerebral cortex, without dialectical treatment, and only needs the appropriate symptoms and signs of the patient. Although only in the wrist and ankle, it can solve a series of problems in the whole body, especially nausea, vomiting and pain symptoms.
Chemotherapy is a cancer therapy performed on advanced cancer with quite good success, but this therapy has quite a lot of side effects. Chemotherapy induced nausea and vomiting or commonly known as CINV, is a condition of nausea and vomiting experienced by cancer patients undergoing chemotherapy, with a prevalence of around 80% of all patients undergoing chemotherapy, and 40% has the potential to become severe. This study aims to determine the efficacy of a new acupuncture modality, namely the press needle, in preventing CINV symptoms in pediatric patients with cancer undergoing chemotherapy.
Chemotherapy is one of the most common treatments for breast cancer, but the adverse effects can be severe enough to delay or make chemotherapy intolerable, thus affecting the efficacy of the disease. Women and younger patients are more likely to experience chemotherapy-induced nausea and vomiting (CINV) . Therefore, antiemetic drugs is a key way to reduce chemotherapy side effects, which ensures compliance, and maintain quality of life. CINV is usually induced by two pathways. The central pathway is mediated by neurokinin-1 (NK-1) receptors, where chemotherapeutic agents stimulate the secretion of substance-P (SP) from the vomiting center located in the medulla oblongata and nucleus accumbens, which binds to NK-1 receptors and induces vomiting. The peripheral pathway is mediated by 5-hydroxytryptamine 3 (5-HT3) receptors, and chemotherapy stimulates intestinal chromophores in the gastrointestinal mucosa to secrete 5-HT3, which binds to its receptors to induce vomiting. Most guidelines currently recommend the combination of 5-HT3 receptor antagonists, NK-1 receptor antagonists, and dexamethasone for high-emetogenic-risk chemotherapy regimens. Usually 5-HT3 receptor antagonists include granisetron, ondansetron, and palonosetron. Palonosetron is a second-generation 5-HT3 receptor antagonist with stronger affinity and higher efficacy than other antagonists. The commonly used NK-1 receptor antagonists are aprepitant and fosaprepitant. Fosaprepitant is an aprepitant prodrug that can be rapidly converted to aprepitant in the body, blocking the binding of substance P to NK-1 receptors for antiemetic purposes. Clinical trial has confirmed that the overall complete response (CR) rate of palonosetron 0.75 mg combined with fosaprepitant and dexamethasone was 54.9%, with 75.9% CR in the acute phase (0-24 h after chemotherapy) and 62.3% in the delayed phase (24-72 h after chemotherapy). Another clinical trial showed an acute phase CR of 89.8% and a delayed phase CR of 90.4% for oral aprepitant combined with intravenous palonosetron 0.75 mg and dexamethasone. The data suggests that both oral and intravenous administration are effective in preventing CINV, but there are no clinical trial results for oral versus intravenous administration. Oral administration is painless, has fewer side effects, and is a safer mode of administration, but bioavailability is different and drug absorption is affected by a variety of factors; whereas intravenous injection has rapid onset of action, but there are risks of injection reactions, phlebitis, and infection. Therefore, we hope to conduct a non-inferiority study on the efficacy of oral and intravenous 5-HT3 receptor antagonists combined with NK-1 receptor antagonists through this trial, which can provide more options for patients by combining the cost and administration methods.
The purpose of this study is to examine the effectiveness of a technology-based intervention for managing nausea and vomiting in older adults with cancer. Participants will be randomized to either an intervention or control group. Outcomes such as symptom severity, quality of life, and resource use will be examined.
This study uses cyclopropofol as a positive control and adopts a large sample, multicenter, randomized, single-blind, positive parallel control test design to explore the clinical application value of cyclopropofol in preventing postoperative nausea and vomiting.
Artificial abortion is the most widely used procedure in termination of first-trimester pregnancy. Cervical ripening before the operation guarantees operative convenience and decreases complications. An overstrained cervical dilation associates with uterine perforation, cervical laceration and cervical incompetence. To address the issue, various mechanical and pharmaceutical methods have been applied to prepare the cervix before transvaginal procedures. Prostaglandin analogues (PGs) play an important role in ripening the cervix or promoting uterine contraction in gynecology and obstetrics. As most tissues express prostaglandin receptors, vomiting, nausea, fever, diarrhea and abdominal pain can hardly be avoided with PGs administration. Longer PGs action contributes to better cervical ripening, but more uncomfortableness at the same time. These annoying symptoms may affect the participants' satisfaction and increase perioperative risks. To balance the safety and effectiveness of the surgery as well as patients' feeling, a proper timing for cervical ripening should be investigated. However, the administration timing of PGs has not reached a broad consensus, ranging from 16 hours to 2 hours before surgery. Carboprost methylate (CM), a PG-F2α analogue, has been used nationwide for cervical ripening in China. To minimize the side effects of PGs without affecting cervical ripening, the investigators intended to explore shortening the action time of CM in cervical preparation before artificial abortion. Thus, the investigators conducted this prospective cohort study and aimed to examine the efficacy of early and delayed vaginal administration of CM before surgery, and optimized both the perioperative safety and participants' convenience. The investigators hypothesize that early vaginal administration of CM would not affect the cervical ripening status, but will greatly reduce the unpleasant complications among the participants.
A prospective longitudinal cohort study that will assess the effect of a Personalized Medicine (PM) clinic recommendations on pharmacogenetic variation and/or interacting drugs on plasma drug exposure, effectiveness or toxicity of commonly used antidepressant, pain, and antiemetic medications in cancer patients. Such recommendations will entail genotype-guided treatment suggestions while also considering potential DDI, and will be provided to patients during their clinic visit, and referring physicians thereafter. Drug concentration and therapeutic effectiveness will be assessed before (baseline) and 6 months after recommendations have been provided. To assess effectiveness, patient-reported outcomes will be evaluated using validated scales for symptoms of depression, pain and chemotherapy-induced nausea/ vomiting The investigators hypothesize that the pharmacogenetic variation and DDI, if applicable, determine steady state drug concentration and therapeutic response or toxicity of the investigated antidepressant, pain or antiemetic treatments at baseline, while there is a clinically significant reduction or absence of the effect 6 months after the PM clinic recommendations to referring physicians and patients.
This is an analytical validation observational cohort study is designed to provide evidence of: safety and reliability of Body Surface Gastric Mapping using the Gastric Alimetry System (GAS), normal reference values, and correlation of metrics with patient symptoms among healthy adults and patients diagnosed with upper abdominal motility disorders. GAS is intended to record, store, view and process gastric myoelectrical activity. This is a proprietary system consisting of multiple electrodes arranged on an array that is placed precisely over the stomach, a reader to collect the electrode measurements and a smart tablet application to track patient reported symptoms. Participants meeting inclusion and exclusion criteria will continue fasting for 30 minutes after the Gastric Alimetry System has been applied and begun measuring, eat a standard study meal within 10 minutes and remain quietly seated, reclining, for 4 hours as the GAS continues to collect data. The array is removed and the abdomen is examined for evidence of skin effects.
