Background~Surgery and anesthesia are related to unwanted adverse events, side effects and postoperative discomfort. Postoperative nausea and vomiting are frequent and the question arises which patient is at specific risk for these sequelae. Some predisposing factors for PONV are well described, e.g. female sex, non-smoking status and postoperative opioids. Some drugs used for anesthesia as well as surgery related variables might induce PONV.~In this prospective association study patient related variables, surgical and anesthesia related variables as well as genetic variants of several candidate genes will be investigated in a well-described patient cohort presenting for scheduled surgery.~Objective~The aim of this study is to investigate a possible association of non-genetic variables and genetic variants with PONV.~Methods~Prospective association study performed in patients recovering form elective surgery and anesthesia.
Prospective observational study to analyse the association of non-genetic variables as well as genetic variants of candidate genes with the incidence of postoperative nausea and vomiting (PONV).
