OR) of each hypothesized risk factor as a coefficient. Volatile anaesthesia may increase PONV by decreasing serum levels of anandamide, an endogenous cannabinoid neurotransmitter that acts on cannabinoid-1 and transient receptor potential vanilloid-1 receptors to suppress nausea and vomiting. Anaesthesia, 1994, Volume 49 (Supplement), pages 34-37 Ondansetron, clinical development for postoperative nausea and vomiting: current studies and future directions A. F. JOSLYN Summary The clinical development of ondansetron for the prevention and treatment of postoperative nausea and vomiting has been progressing for 5 years, and continues as new directions of research are being … Transdermal scopolamine is a cholinergic antagonist typically used to treat motion sickness. 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. Isoflurane, nitrous oxide, Overuse of bag and mask ventilation (due to gastric dilatation). Intraoperative and postoperative opioid use increases the risk of PONV in a dose-dependent manner. subsequently developed a simplified risk score based on data from Koivuranta et al. A summary of the neurotransmitters in the vomiting process: Figure 2 – The pathways and neurotransmitters involved in the control of vomiting. Prophylactic measure includes anaesthetic approaches, conservative measure and prophylaxis. In addition, PONV is regularly rated in preoperative surveys, as the anaesthesia outcome the patient would most like to avoid. Featured Review: Drugs for preventing postoperative nausea and vomiting in adults after general anaesthesia: a network meta-analysis Why are people sick after an operation? Practitioners should systematically implement prophylactic and therapeutic antiemetic strategies based on randomized controlled trials, meta-analyses, and evidence-based consensus guidelines to reduce the institutional rate of PONV. Multifactorial scores are significantly more accurate at predicting the patient's risk of PONV than single risk factors like surgical site, history of PONV, or history of motion sickness (ROC-AUC=0.68, 0.53, and 0.58, respectively). anaesthesia with propofol and nitrogen reduces the incidence of PONV by 30%, making this intervention as effective as an antiemetic drug. Given that the panoply of available antiemetic drugs work on different receptor classes, multiple antiemetics can be safely and effectively combined to further reduce the risk of PONV in high-risk patients. Female gender is consistently the strongest risk factor for PONV with an odds ratio (OR) of ∼3, which indicates that female patients are—on average—three times more likely than men to suffer from PONV. Most scores have an ROC-AUC in the range of 0.65–0.80 due to the limited strength (OR=2–3) of individual predictors, which means that ∼70% of the patients can be correctly classified in terms of risk for PONV. '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.
