It has an incidence of about 25% in adults, with a published range of 5-75%. There are a number of risk factors for PONV. As previously mentioned, antiemetic drugs like ondansetron, dexamethasone, and droperidol are similarly effective, each reducing the patient's risk by 25%.2 Because they work on different receptor classes, their effects are additive.2 Thus, patients at low-to-moderate risk can be given one or two interventions (e.g. Using the patient's risk to tailor antiemetic prophylaxis has been shown to be effective and is thus recommended in expert guidelines.8,9 In doing so, it is important to consider both the patient's risk and the safety and relative efficacy of the available interventions. The probability of PONV, given the presence of the relevant risk factors, is subsequently calculated in a validation dataset. If general anaesthesia is required, total i.v. Older prospective studies reported postoperative retching and vomiting in 11.1%74or nausea and vomiting in 21.1%75of patients after spinal anesthesia. However, there is currently little evidence to support this theory. Figure 1 – Opioid analgesics, such as diamorphine hydrochloride, can induce nausea and vomiting. 2. Last updated: March 25, 2019 Are there other factors contributing to nausea? She vomits approximately twice a day, usually around 10–20 minutes after eating. While the use of nasogastric tubes may increase the incidence of nausea, gastric tube decompression has no effect on PONV. The physiology of PONV is complex and not perfectly understood.

Introduction Nausea and vomiting is a common and distressing symptom or side effect in medicine, surgery and following anaesthesia.
