Multimodal antiemetic therapy and emetic risk profiling.

INTRODUCTION Postoperative nausea and vomiting (PONV) is a common problem with no simple solution. This review highlights factors that are known to increase the risk of PONV. It examines the various data on pharmacological and non-pharmacological methods that have been used to prevent PONV. METHODS Peer-reviewed journals on the subject were covered. CONCLUSION Patient, surgical and anaesthetic factors increase the risk of PONV. While patient and surgical factors are understandably difficult to control, a multimodal approach involving both pharmacological and non-pharmacological interventions has been successfully adopted to reduce the incidence of PONV. Various factors have been identified to categorise patients into different profiles to determine their risk of PONV. Perioperative strategies can then be targeted at these patient groups.
