Active clinical trials for "Postoperative Nausea and Vomiting"

Investigators aim to determine the optimal dose of granisetron in strabismus ophthalmic surgeries under general anesthesia to prevent postoperative nausea and vomiting

this study will aim to evaluate the effects of dexmedetomidine, dexamethasone and Ondansetron on the prevention of postoperative nausea and vomiting in children undergoing dental rehabilitation surgery.

The study has been designed as a prospective randomized clinical trial. Due to the use of a bispectral (BIS) monitor in the interventional arm, the study will not be blinded for the anesthetist. The total planned number of study subjects is 100. Patients will be randomly randomized upon arrival to the operating theatre (using the envelope method) into the interventional arm (BIS monitoring of the depth of general anesthesia), and into the control group (standard management of general anesthesia to minimum alveolar concentration (MAC) 1,0). The target values of the depth of general anesthesia according to BIS are between 40 and 60.

Today, surgical applications are used to solve many health problems. In order for the surgical intervention to take place, anesthesia applications are often required. Complications such as sore throat, thirst and nausea and vomiting may occur as a result of trauma, local irritation and inflammation of the airway mucosa during anesthesia and tracheal intubation. These complications are in the postoperative period; It may cause delayed oral fluid intake, prolonged dehydration, oral odour, and increased risk of aspiration, hematoma and wound dehiscence due to retching and vomiting, all of which may lead to delayed discharge and increased cost. Aromatherapy, one of the non-pharmacological applications, is frequently applied in reducing postoperative complications and its effectiveness is stated. In this study, the aromatic solution applied after the surgery; It was planned to examine the effect on sore throat, thirst, nausea-vomiting. In addition, the multimodal synergistic effect of lavender oil and ginger oil used in the aromatic solution to be prepared will be utilized. As a result of this study, the effectiveness of the aromatic solution application to be applied to the patients in the postoperative period and the benefits and benefits of the patient's recovery process will be determined. Thus, effective application can be made for the entire postoperative period. It is thought that this study to be conducted will be a guide for future studies on the patient group.

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.

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.

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 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.

"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 determine the effectiveness of this medication in preventing nausea and vomiting in female patients at risk for post-operative nausea and vomiting (PONV).
