Active clinical trials for "Nausea"

General anesthetic technique plays a key role in most surgical procedures. This technique has some complications especially postoperative nausea/vomiting (PONV). This complication can lead to serious problems. Department of Anesthesiology has developed and implemented a PONV prophylaxis guideline for high risk PONV patients but PONV still remains.

The study aims to investigate the prevalence and treatment of nausea and/or vomiting in patients with advanced cancer not receiving chemotherapy or irradiation.

Postoperative nausea and vomiting ( PONV ) is one of the common complications after general anesthesia while genetic factors may play an important role in Postoperative nausea and vomiting. In this study, the investigators investigated the relationship between gene polymorphism ( such as single nucleotide polymorphism ) of the gene HTR3A ( 5-hydroxytryptamine receptor 3A ), HTR3B ( 5-hydroxytryptamine receptor 3B ), HTR3C ( 5-hydroxytryptamine receptor 3C ) and TACR1 ( tachykinin receptor 1 ) etc. with nausea and vomiting after general anesthesia. Simultaneously, the investigators explored the influencing factors of nausea and vomiting.

Point-of-care gastric ultrasound will be used to measure stomach contents postoperative in patients who underwent colorectal surgery. Stomach volume and status (empty or full) will be compared retrospectively to the standard clinical criteria for diet advancement to determine if stomach volume via ultrasound is associated with successful diet advancement, nausea/vomiting, nasogastric tube replacement, length of stay, and other clinical outcomes. Clinicians performing clinical care will be blinded to the ultrasound exam results.

Delayed emesis following administration of carboplatin-based chemotherapy despite prophylaxis with standard antiemetic prophylaxis (5-HT3 and corticosteroid) remains a clinically significant and distressing problem for patients with cancer. The incidence of delayed emesis appears to be higher in women compared to men.

Chemotherapy induced nausea and vomiting are common adverse events related to oncologic treatments. It can have deleterious effect on patients' quality of life and could lead to dose reductions and/or discontinuation of treatment. This study aims to quantify the prevalence of nausea and vomiting induced by highly emetogenic chemotherapy in patients who had adequate antiemetic prophylaxis, also to describe the epidemiologic profile and identify predisposing factors.

The most common toxicity of chemotherapy is nausea and vomiting, and appropriate management of these toxicities can help patients improve tolerance for chemotherapy. Anti-emetics including dopamine antagonist, serotonin antagonist, and substance P antagonist administered to patients according to emetogenic risk of chemotherapeutic drugs. However, patients don't always experience same nausea and vomiting for the same drugs. Therefore, it is important to determine the biomarker to predict chemotherapy-induced nausea and vomiting. Some biomarkers studies were done during the chemotherapy. However it is not definite evidence of relations between biomarkers and chemotherapy. We will hope to find any predictive biomarker of CINV.

Postoperative nausea and vomiting (PONV) is a distressing adverse effect that may result in postoperative complications including bleeding, wound dehiscence, aspiration pneumonitis, as well as fluid and electrolyte imbalances Incidence of PONV after general anesthesia is about 30% in all post-surgical patients but up to 80% in high-risk patients despite advances in anesthetics and anesthesia techniques

This study evaluates the effects of complementary medicine (CAM) treatments on patient reported outcomes in hospital settings, for hospitalized people. Various CAM modalities such as acupuncture, reflexology, guided imagery and hypnosis are evaluated. The investigators compare outcomes between two groups: Standard of care (treatments that are provided commonly in hospital) versus standard of care AND CAM treatments. Outcomes assessed are both quantitative i.e. scores on Visual Analogue Scale for various symptoms such as pain, nausea, wellbeing, anxiety, and qualitative such as Measure Yourself Concerns And Wellbeing.

We aimed to evaluate the different ETCO2 levels (with the help of ultrasonographic optic nerve sheath diameter) in preventing gynecological laparoscopic surgeons' postoperative nausea induced by intracranial pressure change due to pneumoperitoneum and trandelenburg position.
