Active clinical trials for "Vomiting"

To evaluate the effectiveness of a prophylactic dose of ondansetron in decreasing the incidence of post-operative nausea and vomiting in cardiac surgery patients after cessation of post-operative sedation. In patients who have undergone open heart surgery, a single prophylactic dose of ondansetron 4 mg IV given at the time of discontinuing propofol sedation will result in a 50% reduction of the rate of post-operative nausea and vomiting in the first 24 post-operative hours compared to placebo.

The intrathecal administration of morphine is gaining popularity. It is easy to do and can reduce the pain after surgery up to 24 hours. However, it causes postoperative nausea and vomiting more than other methods providing postoperative analgesia. Patients suffering from these side effects have to spend a longer period of time recovering in the hospital with high cost of medical treatment.

optimal postoperative pain control with intrathecal morphine, with proper prevention of postoperative nausea and vomiting. Dexamethasone, and or atropine could offer some protection against nausea and vomiting.

Bariatric surgery remains the most effective therapy for obesity. Postoperative nausea and vomiting (PONV) are commonly reported following bariatric surgery. The proposed study focuses on the most common bariatric procedure performed, laparoscopic sleeve gastrectomy (LSG), and aims to assess the effect of a post-operative nausea and vomiting-specific intervention. The investigators hypothesize that the intervention group will experience a reduction of nausea-related prolonged hospital stay and significantly improve patient-reported quality of recovery from surgery and quality of life.

The aim of this study is to evaluate not only the occurrence of side effects, but the quality of the recovery (QoR-40 Questionnaire) of patients submitted to spinal anesthesia with administration of low doses (0.1 mg) of intrathecal morphine for the surgical treatment of fractures in one of the lower limbs and who will receive prophylactic ondansetron (4mg), dexamethasone (8mg) or placebo.

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.

The study aims to compare between two bolus doses of dexmedetomidine in preventing PONV in highly susceptible patients.

The primary objective is to evaluate the efficacy of two different doses of IV palonosetron in the prevention of chemotherapy induced nausea and vomiting in MEC and HEC patients through 120 hours after start of chemotherapy in single and repeated chemotherapy cycles. The secondary objectives are to evaluate the safety and tolerability of IV palonosetron in pediatric patients and evaluate the pharmacokinetics of IV palonosetron in a subset of pediatric CINV patients.

Gynecological surgery is associated with a high incidence of postoperative nausea and vomiting. NK1 receptor antagonists such as aprepitant appear to be highly effective for treating acute and delayed emesis, and yet understanding of the efficacy of different doses of aprepitant is limited. We performed a prospective, randomized, double-blinded placebo-controlled study of 123 female adults scheduled for laparoscopic hysterectomy who received 80 mg aprepitant, 125 mg aprepitant, or a placebo.

This study is being done to determine the efficacies of two preventative drug combinations for postoperative nausea and vomiting in patients undergoing neurosurgery. The aim of this study is to compare the efficacy of using aprepitant instead of ondansetron in combination with dexamethasone and promethazine for post-operative nausea and vomiting prophylaxis. By completing this comparison study investigators will determine the most efficacious drug combination which will allow us to enhance the overall comfort and satisfaction of neurosurgical patients in the immediate postoperative period.
