Active clinical trials for "Postoperative Nausea and Vomiting"

This is an observational study with the goal of determining the costs of nausea and vomiting in ambulatory patients after surgery from the US societal perspective.

This prospective observational study aims to evaluate the influence of somatic symptom load and anxiety sensitivity as risk factors for the occurrence of postoperative nausea and vomiting (PONV). Physiological and psychological variables are assessed in female patients with an increased risk for PONV prior to a planned surgical intervention with a 33-item questionnaire composed of the ASI-3 and the PHQ-15. Postoperative evaluation includes the occurrence of nausea and vomiting in the first 24 hours after surgery. It is hypothesized that patients with high sum scores for somatic symptom load (measured with the Patient Health Questionnaire, PHQ-15) and with increased levels for anxiety sensitivity (measured with the Anxiety Sensitivity Index, ASI-3) experience more frequently postoperative nausea and vomiting (PONV) than patients with low scores in both self-rating instruments.

The hypothesis of this study is that controlled release oxycodone can be safe and well tolerated for the control of postoperative pain in surgery for head and neck cancer. The primary objective is to study the safety and the incidence and severity of adverse effects, and the secondary objective is to evaluate the analgesic efficacy and identify the frequency of use of rescue medication and the prescribing physician's opinion about the quality of postoperative analgesia with oxycodone controlled release in oncologic surgery of the head and neck.

Postoperative nausea and vomiting after outpatient surgery are significant sources of patient dissatisfaction. The prevention of postoperative nausea and vomiting (PONV) should be equally as important as prevention of pain because both are large sources of patient dissatisfaction and can necessitate admission after routine outpatient procedures. None of the currently available pharmacological interventions are able to totally abolish PONV. The use of electroacustimulation is a useful adjunct in prevention of PONV, but has yet to be studied when the patient takes the device home with them after leaving an outpatient facility.

The primary objective of this study is to measure the prevalence of preoperative dehydration in elective major abdominal urologic surgery when we apply our daily standard operation procedures. Secondary objectives are to assess the impact of preoperative dehydration on postoperative outcome. The hypothesis is that preoperative dehydration leads to more postoperative complications.

This project intends to develop and implement an electronic reminder for post-operative nausea and vomiting (PONV) prophylaxis into the Anesthesia Record Keeping System. Each patient will have his or her PONV risk classified based on the following risk factors: Female gender, History of PONV, History of Motion Sickness, Non-smoker and Duration of procedure > 60 minutes. Patients will be randomized to either receive the PONV reminder or not. Those receiving the PONV reminder will have the PONV risk assessment and current guideline information for PONV prophylaxis displayed on the Anesthesia Record Keeping System (ARKS) screen at the beginning of the case. At the end of the procedure (specific at documentation of emergence), the reminder will assess the current status of PONV prophylaxis as per anti-emetic medications administered and compare the current status to the recommended status based on published guidelines. If the current status is compatible or exceeds the recommended status the reminder will silently document compliance. If published guidelines suggest additional PONV prophylaxis based on the patients risk profile and a comparison with the currently documented status, an electronic reminder will appear on the ARKS screen to alert the anesthesia provider of an opportunity to enhance guideline adherence. The reminder will not recommend a specific medication, intervention or therapy. It will be completely the decision of the anesthesia provider if and how to modify the PONV prophylaxis for the patient. Subjects randomized to not receive the electronic display will have it deactivated.

The purpose of this study is to see if the nicotine patch reduces post operative nausea and/or vomiting (PONV) among non-smoking patients who are at high risk of PONV.

Postoperative nausea and vomiting (PONV) is one of the most commonly reported adverse effects of anesthesia. The general incidence of vomiting is approximately 30%, nausea at 50% and the PONV rate can go up to 80% in high-risk patients without prophylaxis. Prevention of these episodes in high-risk patients improves satisfaction and well-being rates. Therefore, it becomes important the adequate control of PONV, aiming at the satisfaction of the patient with the procedure, lower costs for the health system as well as reduction of complications in the postoperative period. This study aims to evaluate the association of gabapentin or pregabalin with dexamethasone in reducing the incidence of PONV in high-risk patients undergoing laparoscopic surgeries in the first 48 hours postoperatively as well as to assess side effects.

The purpose of this follow up study is to determine the duration of action regarding aromatherapy to treat nausea occurring postoperatively.

At the child, the post-operative vomitings (POV) remain the main post-operative complication in term of frequency. They also represent the first cause of unforeseen hospitalization in day case surgery. The causes of POV are multiple, including in particular the post-operative prescription of opioids. The role of the premature refeeding remains discussed. Up to the age of 4 years, acute pain is difficult to distinguish from other causes of distress (anxiety, anger but also hunger) being able to make prescribe wrongly opioids in post-operative. The main objective of this study is to estimate the POV in pediatric day case surgery after early refeeding with clear liquids in the recovery room or only in the day case wards (usual practice). The secondary objectives are to estimate the time on returning to the day case ward, at home, the post-operative opioid consumption, early refeeding adverse effects (desaturation, swallowing trouble)
