Active clinical trials for "Vomiting"

The aim of this randomized trial is to assess the efficacy of SPI-directed analgesia for vitreoretinal surgeries (VRS), presence of PONV and oculocardiac reflex (OCR) and compare Numerical Rating Scale (NRS) with Surgical Pleth Index (SPI) for monitoring pain perception postoperatively. Patients received general anaesthesia alone or combined with either preemptive analgesia using topical solution of 0,5% proxymetacaine or peribulbar block (0,5% bupivacaine with 2% lidokaine) or preemptive intravenous infusion of 1,0 g of metamizol or preemptive intravenous infusion of acetaminophen in a doseof 10-15mg/kg of body weight.

Introduction. Despite the advantages associated with the use of remifentanil during total intravenous anesthesia (TIVA), it has been observed a frequent difficulty in the control of postoperative pain due to the risk of developing hyperalgesia and acute tolerance associated with the administration of this opioid. There is evidence that NMDA receptors are involved in the development of these changes. Methadone is an opioid that exhibits analgesic potency similar to that of morphine but has NMDA antagonist activity and longer duration of action as additional features. The objective of the study was to evaluate the quality of recovery (QoR40) of patients undergoing TIVA for laparoscopic cholecystectomy and who received morphine or methadone to control postoperative pain. Methods. Patients aged 18 to 65 years, physical status ASA I and II, submitted to total venous anesthesia (propofol and remifentanil) for laparoscopic cholecystectomy and eligible to participate in this prospective and randomized clinical study will be evaluated. After induction of anesthesia, patients will receive a solution containing 0.1 mg.kg-1 morphine (MF group) or 0.1 mg.kg-1 methadone (MT group). Data on the presence of pain, nausea, vomiting, tremor, drowsiness, presence of SpO2 <92%, even with O2 face mask (5 L.min-1) and length of stay will be recorded at PACU. The pain will be evaluated every 15 minutes on a verbal numerical scale (ENV) from 0 to 10. E.v. morphine 0.1 mg.kg-1 (MF group) or methadone 0.1 mg.kg-1 (MT group) will be administered every 15 minutes to obtain the score below 3. After discharge from the PACU, all patients will receive intravenous ketoprofen every 12 hours and dipyrone every 6 hours. For cases where the patient considers the analgesic regimen insufficient, tramadol (100 mg) will be administered intravenously at 8-hour intervals. The consumption of analgesics, the intensity of pain, the occurrence of nausea, vomiting and other complications in the ward will be recorded. The application of the questionnaire (QoR40) will be performed in the ward the morning after the surgery by a medical student.

This is a randomized, placebo-controlled trail, the objective of this study is observation the effect of sub hypnotic dose of propofol for prevention of nausea and vomiting induced by hemabate during spinal anesthesia for elective cesarean section. The primary outcome is the presence of post-delivery intra-operative nausea and vomiting in parturients. The patients demographic characteristics, blood pressure, sensory block level, and the medications will be collected.

The purpose of this study is to determine how automated recommendations are best presented to optimize the adherence to guidelines on prophylaxis for nausea and vomiting after surgery.

Postoperative nausea and vomiting (PONV) is a common problem after general anesthesia. The incidence can be as high as 80 percent in high-risk patients. Investigators designed this randomized, double- blind, single-center study to compare the efficacy of the combination of dexamethasone with ondansetron and dexamethasone with aprepitant undergoing laparoscopic surgery. Seventy American Society of Anesthesiologist (ASA) physical class I-II, age 18-60 years patients scheduled for laparoscopic surgery were included in this study. Anesthesia was induced with propofol, fentanyl, and rocuronium, and maintained with sevoflurane in oxygen / air mixture in all patients. Remifentanil was continuously infused during surgery. Patients were randomly divided into two groups. Patients in the dexamethasone and aprepitant group (group DA, n=35) received 40 mg aprepitant orally 1 to 2 hours before induction of anesthesia and 2 ml saline intravenous (iv) within the last 30 minutes of surgery. Patients in the dexamethasone and ondansetron group (group DO, n=35) received an oral placebo identical to aprepitant 1 to 2 hours before induction of anesthesia and 4 mg ondansetron iv within the last 30 minutes of surgery. All patient received iv 8 mg dexamethasone after induction of anesthesia. PONV and postoperative opioid consumption were assessed for 24 hours postoperatively. The blindly evaluated primary outcome was complete response. The secondary outcomes were incidence of nausea, retching or vomiting, the need of rescue antiemetic and opioid consumption within 24 hours after surgery. Statistical analyses were performed using Mann-Whitney U test, Chi-square test, and Fisher's Exact test. P<0.05 was considered statistically significant.Investigators hypothesized that the antiemetic efficacy of the aprepitant and dexamethasone combination is superior compared with ondansetron and dexamethasone combination following the laparoscopic surgery.

The purpose of this study is to evaluate the benefit of addition of droperidol to prophylaxis with ondansetron and dexamethasone in children with high risk of postoperative vomiting (POV). In adults some authors showed that the effectiveness of prophylaxis is correlated to the number of molecules or specific procedures used.

To investigate the role of postoperative nausea and vomiting risk factors assessment after cardiac surgery. We designed a randomized controlled study comparing standard care (no risk factor assessment and no intervention) with prophylaxis of postoperative nausea and vomiting after cardiac surgery in high risk patients. Prophylaxis of postoperative nausea and vomiting by betamethasone (4mg) and/or droperidol (0.625mg) immediately after cardiac surgery, depending on risk factors (if risk score is over 2) in the intervention arm.

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.

This will be a blinded study to compare the absorption of topical haloperidol with placebo

The purpose of this study is to find out whether or not adding aprepitant(Emend®) to the standard therapy will help children who receive chemotherapy to have less nausea and vomiting.
