Active clinical trials for "Postoperative Nausea and Vomiting"

This study is being done to determine the efficacies of two preventative drug combinations for postoperative nausea and vomiting in patients undergoing neurosurgery. The aim of this study is to compare the efficacy of using aprepitant instead of ondansetron in combination with dexamethasone and promethazine for post-operative nausea and vomiting prophylaxis. By completing this comparison study investigators will determine the most efficacious drug combination which will allow us to enhance the overall comfort and satisfaction of neurosurgical patients in the immediate postoperative period.

Ketamine added to intravenous patient-controlled analgesia may be effective on prevention of postoperative nausea and vomiting by reducing opioid requirement after surgery.

PONV after intrathecal morphine, occurs up to 30-40 percent. The patients having TKR normally are female, obese and non-smoker which are risk factors for PONV. Recently, a multimodal approach, combining several means to minimize PONV, has found wide acceptance as a standard of care. In our hospital, most of the patients are supposed to fast after midnight The oral rehydration therapy reduce patients thirst and increase his satisfaction, but whether or not this method can reduce the incidence of PONV after low dose (0.2 mg) intrathecal morphine is not investigated yet. The aim of this study is to investigate the effect of preoperative oral rehydration therapy on the incidence of PONV.

The study drug, Aprepitant, is currently used to control chemotherapy induced nausea and vomiting and is also approved for post-operative nausea and vomiting. The investigators' evaluation of it in morbidly obese patients will demonstrate its ability to control nausea and vomiting post-operatively in this subset of patients.

The purpose of this study is to assess the safety and efficacy of 2 doses of an approved drug for a new indication in the prevention of postoperative nausea and vomiting in patients receiving general anesthesia for open abdominal surgery requiring overnight hospital stay.

Background: Highly selective α-2 agonist dexmedetomidine in increasingly used as an intrathecal adjuvant for caesarean section performed under subarachnoid block. Aim of the Study: The aim of the study is to determine whether low dose dexmedetomidine added to local anesthetic for spinal anesthesia will attenuate perioperative nausea and vomiting and shivering in lower segment caesarean section (LSCS) with minimal hemodynamic instability or not. Patients and Methods: Sixty parturients planned for elective CSs under spinal anesthesia were enrolled in this prospective controlled study and randomly divided into two equal groups. Spinal block was achieved with 10mg hyperbaric bupivacaine 0.5% plus 5µg dexmedetomidine (group D) (dexmedetomidine group) or 0.2 ml normal saline (group C) (control group). Hemodynamic parameters, incidence of nausea and vomiting and shivering were recorded. Keywords: Dexmedetomidine, Cesarean Section, Bupivacaine, Spinal Anesthesia, Shivering, PONV

The investigators investigate the association between the administration of glycyrrhizin during induction of general anesthesia and the occurrence of postoperative nausea and vomiting (PONV) in patients undergo breast surgery

Postoperative nausea/vomiting (PONV) is a common problem following surgery and anesthesia. There are risk factors that increase the incidence of PONV that are related to the patient, to the surgical procedure or to the anesthetic agents. At the subjective level PONV is described as worse and more feared than postoperative pain by many patients. At the objective level it increases the length of stay in the recovery room, it results in unplanned hospital admission and Emergency Room visits, and therefore increased cost of care. A lot of research work has been done to identify pharmacological agents to prevent and treat PONV. The higher the risk of a patient the higher number of these drugs are combined for prophylaxis. However, these drugs have significant side effects of their own. Much less attention has been paid to potential non-pharmacological PONV prevention options. The purpose of our study is to investigate the putative role of the natural stimulation of normal gastrointestinal function via the Pavlovian reflex. We seek to find a natural method with no side effects to improve PONV prophylaxis in patients with risk factors for that postoperative complication.

Laparoscopic sleeve gastrectomy (LSG) is an emerging treatment modality among the various types of surgical approach to obesity (1). The incidence of PONV in obese patients undergoing bariatric surgery, who did not receive antiemetic prophylaxis, is high at nearly 70-80 % (2,3). Postoperatively, bariatric patients appear to suffer from nausea and vomiting more frequently than normal weight or obese patients.

Breast cancer is one of the three most common cancers worldwide, and the primary treatment method is surgery.Since most patients are non-smokers who use opioids in the postoperative period, which are known risk factors for postoperative nausea and vomiting (PONV) according to the Apfel Risk Score. Breast surgery was identified as a strong risk factor for PONV. According to the previous studies, the incidence of PONV is 30-70% in patients undergoing the breast cancer surgery, which not only gives patients unpleasant and painful experience, but also prolongs the hospital stays and delay patient discharge and adds to hospital costs. We compared the effects of dexamethasone alone vs. in combination with Pericardium 6 (P6) electrical stimulation or granisetron for inhibition of PONV in women undergoing breast cancer surgery.
