Active clinical trials for "Postoperative Nausea and Vomiting"

Ambulatory surgery is occurring with rapidly increasing frequency as surgical and anesthetic techniques have improved and pressure to reduce health-care costs has increased. While there are many benefits to recovering from surgery within the home, a significant disadvantage is the lack of rapid access to a healthcare provider when postoperative complications occur. Postoperative nausea and vomiting (PONV) are common after surgery and anesthesia, and recent studies have demonstrated a high incidence of post-discharge nausea and vomiting (PDNV) after ambulatory surgery, particularly in high-risk groups (female gender, age less than 50 years, history of PONV, opioid administration in the post-anesthesia care unit (PACU), and nausea in the PACU). Current practices known to reduce the risk of postoperative nausea and vomiting in the PACU, such as the avoidance of volatile anesthetics and the use of intraoperative ondansetron and steroids, have little effect on the risk of delayed PDNV. Novel strategies to prevent PDNV are needed. Orally administered olanzapine, which has been shown to decrease the incidence of chemotherapy-induced nausea and vomiting, demonstrates promise as a novel strategy for preventing PDNV. It has a long half-life, allowing for a single dose to be administered preoperatively. This study will evaluate whether there is a difference in the incidence and severity of PDNV between patients who receive oral olanzapine versus placebo prior to general anesthesia for ambulatory surgery.

PONV (Postoperative nausea and vomiting) is one of most common complications after general anesthesia. Female sex, history of PONV, motion sickness, nonsmoker status, use of volatile agents, duration of anesthesia, opioid administration and laparoscopic surgery are known as risk factors for developing PONV. In consequence, patients undergoing laparoscopic gynecologic surgery are at high risk for developing PONV. Most of these patients use fentanyl based IV-PCA. And it also causes PONV. So, we should prevent PONV in these patients by using multimodal or combination therapy. Aprepitant is a NK1 receptor antagonist.And it is used to prevent chemotherapy induced nausea and vomiting. Many studies using aprepitant to prevent PONV are in progress. In this study, we investigate the effect of combining aprepitant with ondansetron in high-risk patients for PONV.

To assess the efficacy and safety of different doses of APD421 in the prevention of post-operative nausea and vomiting (PONV) in adult patients at moderate to high-risk of PONV. Patients must be undergoing elective surgery under general anaesthesia (hysterectomy (any surgical technique), cholecystectomy (any surgical technique) or "other" elective surgery scheduled to last at least one hour from induction of anaesthesia), requiring at least one overnight stay in hospital, and have at least 2 of the following risk factors for PONV: Past history of PONV and/or motion sickness; Non-smoking status; Female gender; Planned opiate use for post-operative analgesia.

To compare ondansetron, metoclopramide, diphenhydramine, and placebo in order to determine which anti-emetic is most efficacious as a "rescue therapy" for pediatric patients ages 3-18 who have post-operative vomiting after a standardized prophylactic regimen of ondansetron and dexamethasone. We hypothesize that anti-emetics with a different mechanism of action than the prophylactic regimen will be the most effective "rescue therapy" in children having surgery in an ambulatory surgery center. Problem: Despite commonly-used anti-emetics for prophylaxis, some children still go on to develop post-operative vomiting (POV). Goal: To determine which anti-emetic--ondansetron, metoclopramide, diphenhydramine, or placebo--is most efficacious for pediatric patients in this situation. Hypothesis: Anti-emetic medications that have a different mechanism of action than the prophylactic regimen will be the most efficacious "rescue therapy." Hypothesis: Metoclopramide at the dose of 0.5 mg/kg (max dose 20 mg) will be more effective than ondansetron, diphenhydramine, or placebo as "rescue therapy."

"The purpose of this investigator-initiated study is to see if giving dextrose fluid in the veins (IV) decreases the risk of postoperative nausea and vomiting (PONV) in female urologic, gynecologic and breast outpatient surgery patients and at what blood surgery level. The reason for this study is that IV dextrose has been shown to decrease the incidence of PONV and the use of medications to treat PONV, while leading to sooner discharge after surgery. This can decrease overall healthcare cost and improving patient satisfaction."

The purpose of this study is to study the effect of dexamethasone combined with ondansetron on postoperative nausea and vomiting in patients with patient-controlled analgesia after video-assisted thoracoscopic surgery.

Hypothesis: Aprepitant plus ondansetron is more effective than ondansetron plus placebo for prevention of postoperative emesis in patients at moderate-to-high risk for PONV for up to 48 hours after surgery. Specific Aim: To determine the incidence of PONV during the first 48 hours after surgery; in patients who have received aprepitant plus ondansetron versus ondansetron plus placebo for up to 48 hours after surgery.

The purpose of this study is to determine the effectiveness of this medication in preventing nausea and vomiting in female patients at risk for post-operative nausea and vomiting (PONV).

The objective of the study is to assess the safety and efficacy of two doses of IV palonosetron each administered as a single dose for the prevention of postoperative nausea and vomiting through 72 hours postoperatively in children aged 28 days up to 16 years inclusive undergoing surgical procedures requiring general endotracheal inhalation anesthesia.

Despite the development of new drugs, nausea and vomiting after surgery (PONV) are still frequent. Antagonists 5HT3 receptors, such as ondansetron and palanosetron, are among the main characterized prophylactic agents in patients at high risk, however there are few studies comparing the efficacy of these drugs and no study that addresses women aged over 60 years. In this prospective, randomized, double-blind study, 80 women nonsmokers, undergoing laparoscopic cholecystectomy will be divided into two groups, receiving during anesthetic induction intravenous ondansetron 4 mg (n = 40) or palonosetron 75 mcg (n = 40) prophylaxis of PONV.
