constipation, headache) to ondansetron. anaesthesia with propofol and nitrogen reduces the incidence of PONV by 30%, making this intervention as effective as an antiemetic drug. Antiemetics work on several different receptor sites to prevent Isoflurane, nitrous oxide, Overuse of bag and mask ventilation (due to gastric dilatation). Found an error? Therefore, antiemetics administered as rescue treatment for PONV should be of a different class than the drug administered as prophylaxis.9.

Postoperative nausea and vomiting is the phenomenon of nausea, vomiting, or retching experienced by a patient in the postanesthesia care unit or within 24 hours following a surgical procedure. 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 … Fig 3 – IV fluid infusion is a conservative treatment for PONV, *A recent study showed 8mg dexamethasone significantly reduces the incidence of PONV at 24 hours and the need for rescue antiemetics for up to 72 hours in patients following large and small bowel surgery. TIVA, antiemetic drugs), whereas patients at high risk can receive three or four interventions. The CRTZ communicates with the NTS primarily via dopamine-2 (D2) receptors. Some risk factors, like gynaecological surgery, are associated with a high incidence of PONV. 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. The management of post-operative nausea and vomiting can be divided into three areas; prophylactic, conservative and pharmaceutical. Sébastien Pierre, MD, Rachel Whelan, Nausea and vomiting after surgery, Continuing Education in Anaesthesia Critical Care & Pain, Volume 13, Issue 1, February 2013, Pages 28–32, https://doi.org/10.1093/bjaceaccp/mks046. Post-operative nausea . Therefore, the major risk factors for PONV appear to be patient-specific and anaesthesia-related. Post Operative Nausea & Vomiting 1. To develop a predictive risk score for PONV, multivariable analysis is applied to an evaluation dataset to quantify the weight (i.e. For Permissions, please email: journals.permissions@oup.com, Copyright © 2020 The British Journal of Anaesthesia Ltd.
