It is an unpleasant complication that affects about 10% of the population undergoing general anaesthesia each year. Metoclopramide use has been associated with extrapyramidal and sedative side-effects. headache for ondansetron) to potentially severe (e.g. In general, the type of surgery cannot provide reliable, reproducible, and clinically relevant information for assessing the patient's risk of PONV in adult patients. Find out more >> Untreated, one third will have postoperative nausea, vomiting, or both. independent) risk factors is likely to be more robust. To reduce the incidence of PONV without increasing the risk of unnecessary side-effects, antiemetic prophylactic regimens should be tailored to the patients most likely to experience PONV. Cyclical vomiting syndrome - this is characterised by recurrent, discrete episodes of vomiting in an otherwise healthy person, usually a child. According to a randomized controlled trial in over 5000 patients, the use of a short-acting opioid-like remifentanil instead of fentanyl does not decrease the incidence of PONV.2. The following drugs are characterized by less favourable side-effect profiles or limited evidence of efficacy. Once you've finished editing, click 'Submit for Review', and your changes will be reviewed by our team before publishing on the site. Low ASA physical status (I–II), history of migraine, and preoperative anxiety have all been associated with an increased risk of PONV, although the strength of association varies from study to study. QT prolongation). Anticipatory or anxiety-induced nausea and vomiting appears to originate in the cerebral cortex, which communicates directly with the NTS via several types of neuroreceptors. Postoperative nausea and vomiting (PONV), postoperative vomiting (POV), post-discharge nausea and vomiting (PDNV), and opioid-induced nausea and vomiting (OINV) continue to be causes of pediatric morbidity, delay in discharge, and unplanned hospital admission. A range of antiemetic medications are available and are often used in combination. 's group and their own previous data that could be applied across centres and that reduced the number of risk factors in the model from five to four. anaesthesia with propofol and nitrogen reduces the incidence of PONV by 30%, making this intervention as effective as an antiemetic drug. Nonetheless, precise data on optimal dosage, timing, and safety are lacking. Despite implementation of and adherence to consensus guidelines, a significant number of patients still suffer from PONV in the post-anaesthesia care unit, in the hospital, and at home. Some studies have shown that gynaecological, ophthalmological, otological, and thyroid surgery can each increase the risk of PONV. In addition to the ROC-AUC, a more important measurement of the score is its utility, assessed using a calibration curve that compares predicted and observed PONV incidences in a population. Outpatients should be offered rescue treatment that can be administered orally or in a patch application (e.g. Nausea and vomiting may occur separately or together. transdermal scopolamine). Three classes of antiemetic drugs,56 serotonin antagonists (e.g. By plotting sensitivity against the false-positive rate (1-specificity), the area under the receiver operating characteristic curve (AUC-ROC) can be calculated to describe the score's ability to discriminate between patients who will and will not experience PONV.
