Active clinical trials for "Postoperative Nausea and Vomiting"

Postoperative nausea and vomiting (PONV) is one of the most common and distressing postoperative complications. PONV risk assessment is recommanded to determine the number of medications or strategies for prophylaxis. Many well-known risk factors have been determined. However, no study has explored liver surgery-specific risk factors. This study aims to identify whether there was an association between portal vein occlusion and PONV among patients after liver surgery. Patients diagnosed with liver cancer and undergoing hepatectomy will be prospectively consecutively recruited. All enrolled patients receive PONV assessments within the first 24 postoperative hours. Logistic regression models will be used to investigate the effects of portal vein occlusion and the other variables on the occurrence of PONV in both univariate and multivariate analyses

Postoperative nausea and vomiting (PONV) is a common problem and may lead to catastrophic complications, especially in neurosurgical cases. The aim of this study was to evaluate the effects of dexamethasone and ondansetron for preventing PONV in patients who underwent microvascular decompression surgery (MVD).

The purpose of the Study is to test a higher dose of steroids(Dexamethasone) given just prior to surgery in the setting of Fast-Track Knee surgery with Arthroplasty in a group of expected High Pain Responders and the effect on postoperative pain and postoperative inflammation.

Sleeve gastrectomy is the most performed bariatric procedure worldwide. Postoperative pain management is a challenging issue. In this trial, the investigators aimed to explore the effects of laparoscopic guided transversus abdominis plane (TAP) block on postoperative pain management in patient those were performed laparoscopic sleeve gastrectomy.

Aromatherapy is the therapeutic use of essential oils from plants for the improvement of physical, emotional, and spiritual well-being. Healthcare providers play an important role in improving the care of patients with nausea. Aromatherapy is a complementary therapy that may help with post-operative nausea in the adult post-operative bariatric patient population. The purpose of this study is to evaluate the effects of aromatherapy intervention on nausea levels with post-operative bariatric patients once they are on the surgical unit.

Tonsillectomy is one of the most frequent surgical operations performed in children [1-4]. It is usually associated with postoperative nausea and vomiting (PONV) with an incidence ranging from 23% to 73% [2]. Dexamethasone has been shown to be effective in reducing PONV after tonsillectomy using standardized anesthetic technique [2, 5-7]. Previous studies utilizing a different technique, the pre-incision infiltration of local anesthesia, had shown to decrease post-tonsillectomy pain, reduce analgesic consumption and provide a rapid return to normal activity [8, 9]. Given the effectiveness of dexamethasone and the pre-incision infiltration anesthetic technique, it would be beneficial to compare the effect of each on PONV.

Postoperative pain and nausea-vomiting (PONV) are the first causes of failure in ambulatory care in pediatric surgery. Actually, the paracetamol/ketoprofen combination in intraoperative care is recommended for effective postoperative analgesia in children. However, intravenous ketoprofen doesn't have the marketing authorization for use in children less than 15 years old and its use is mainly justified by the absence of therapeutic alternatives. Recently, findings from published studies suggest that dexamethasone (DXM), which is actually recommended to prevent PONV for children "at risk", at a dose of 0.1mg/kg, would have analgesic properties above 0.15 mg/kg comparable to non-steroidal anti-inflammatories (NSAI). Main objective : To examine the effects of intraoperative DXM (0.2mg/kg and 0.4mg/kg) on the intensity of postoperative pain in the post-anaesthetic care unit (PACU) compared to ketoprofen (1mg/kg). Secondary objectives : To examine the effects of intraoperative DXM (0.2mg/kg and 0.4mg/kg) compared to ketoprofen (1mg/kg) on the anesthesia emergence delirium, the intensity of postoperative pain, the consumption of rescue analgesics and the side effects in the first 24 hours after surgery.

Postoperative nausea and vomiting (PONV) remain a significant challenge in our practice. However, pharmaceutical prophylaxis is only partially effective and can imply unpleasant adverse effects. Accordingly, the use of non-pharmacological methods in preventing PONV is appropriate. Acupuncture is reported to reduce PONV and pain, and the adverse events are minimal. The objective of this multicentre, double-blinded, randomized, controlled trial is to investigate whether acupuncture can be a supplementary to the ordinary treatment in children undergoing tonsillectomy and/or adenoidectomy. In addition, the non-specific effect of parental attitudes and expectations on the outcomes will be explored. Two hundred and eighty patients will be included and randomized into two groups Treatment group: acupuncture treatment (approximately 15 to 20 minutes) during anaesthesia and standard treatment Control group: standard treatment The primary endpoints in the intervention study are nausea, retching, vomiting and pain during 24 hours postoperatively. The effect of acupuncture will be studied with regard to any association with possible factors of predisposition to PONV, as well as with other factors registered during the study. Adverse events from acupuncture will be registered. The objective of the self-report questionnaires is to investigate parental attitudes and expectations to the acupuncture treatment pre- and postoperatively compare data of the outcomes from the intervention trial with data from the questionnaires, in order to find any correlation between parental beliefs, attitudes and expectations, and the effect of the acupuncture treatment

Dexamethasone is a synthetic corticosteroid that has been proven to be effective and relatively safe for the prophylaxis of the postoperative nausea and vomiting (PONV). However, little is known about its effect on the hypothalamic-pituitary-adrenal (HPA) axis after surgery. The investigators hypothesize that it will inhibit the normal physiologic HPA surge and reduce cortisol levels post-operatively ia a dose-dependant fashion. To answer this question, the investigators will conduct a randomized, double-blinded placebo-controlled trial with two different doses of dexamethasone in women undergoing elective gynecologic laparotomy.

This study was designed to evaluate the treatment efficacy and safety of palonosetron for the patients who undergo laparoscopic gynecologic, abdominal or other surgery under general anesthesia.
