There are a number of risk factors for PONV. Postoperative nausea and/or vomiting (PONV) is an unpleasant experience that afflicts 20–30% of surgical patients after general anaesthesia.1 PONV decreases patient comfort and satisfaction, and, rarely, may cause dehydration and electrolyte imbalances, aspiration of gastric contents, oesophageal rupture, suture dehiscence, and bleeding.2–9 PONV and its resulting complications are costly for the healthcare sector worldwide, with several hundred million dollars spent annually in the USA alone.10 P… 6and Koivuranta et al. Nausea and vomiting were recorded as two different end points, using a quantitative analysis. Please enable it to take advantage of the complete set of features! 6,8,11,13,21,22History of migraine majored nausea without any influence on vomiting. The intensity of pain was also evaluated at the same time as nausea using a VAS. Postoperative nausea and vomiting … as a risk factor for postoperative nausea (OR 4.25, 95% CI 2.3–7.8) and vomiting (OR 2.62, 95% CI 1.4–4.9). 2020 Oct 28;9(11):3477. doi: 10.3390/jcm9113477. 2006 Jun;22(6):1093-9. doi: 10.1185/030079906X104830. Although some authors have suggested that incidence of PONV is increased in obese patients, we were not able to identify a high BMI as a risk factor in the bivariate Dale model. , the time period during which pain VAS was above the critical threshold (h). Positive coefficients are associated with an increased risk of developing the complication (OR > 1). Can Anaesth Soc J 1984; 31: 178–87, Lerman J: Surgical and patient factors involved in postoperative nausea and vomiting. COVID-19 is an emerging, rapidly evolving situation. 1–13It is assumed that PONV has a multifactorial origin, such as patient-related factors (e.g. Studies published to date have used a variety of methodologies that do not permit meaningful conclusions to be drawn. Postoperative nausea and vomiting (PONV), postoperative vomiting (POV), post-discharge nausea and vomiting (PDNV), and opioid-induced nausea and vomiting (OINV) continue to be causes of pediatric morbidity, delay in discharge, and unplanned hospital admission. Postoperative nausea scores, expressed as area under the nausea–VAS time curve (AUC) was 2.9 ± 11.4 cm × h, mean VAS 0.32 ± 0.83 cm and VASmax 0.7 ± 1.8 cm. In the subsequent study, nausea and vomiting were considered as the two outcomes of interest. Inclusion was prospective and consecutive. It is commonly stated that risk factors for postoperative nausea are the same as for vomiting. Patients with vascular surgery were excluded from the analysis because of a singularity in the maximum likelihood estimation process; this was explained by the fact that only one vascular patient experienced vomiting alone as seen in table 4. In the Dale model, one has to estimate (1) the regression coefficients of the covariates for nausea, (2) the regression coefficients of the covariates for vomiting, and (3) the association parameter between nausea and vomiting. 2020 Dec 3;20(1):297. doi: 10.1186/s12871-020-01214-4. The study included 671 consecutive surgical inpatients, aged 15 yr or more, undergoing various procedures. Table 4. Distribution of Patients According to Postoperative Nausea and Vomiting. Results were expressed as mean ± SD for quantitative variables and as proportions for categorical factors. Our data showed that the dose of administered morphine significantly increased the incidence of nausea and vomiting. 36Furthermore, nausea intensity was assessed using a VAS device as a secondary end point. Results were considered to be significant at the 5% critical level (P < 0.05). Factors considered to have a possible effect on the risk of experiencing PONV (nausea and/or vomiting) included age, female gender, body mass index (BMI), nonsmoking status, history of migraine, motion sickness and PONV, type of anesthesia (general or locoregional), and type and duration of surgery (> 100 min or not). A clear relationship can be seen between the two outcomes and type of surgery.

Acta Anaesthesiol Scand 1998; 42: 495–501, Apfel CC, Greim CA, Haubitz I, Grundt D, Goepfert C, Sefrin P, Roewer N: The discriminating power of a risk score for postoperative vomiting in adults undergoing various types of surgery. Nevertheless, our patients benefited from formal acute pain management in the form of an acute pain service. 2006 Sep;64(9):1385-97. doi: 10.1016/j.joms.2006.05.024. Postoperative nausea and vomiting (PONV) is a patient-important outcome; patients … PONV risk factors have been described in the literature since the late 1800s (20). To identify among preoperative and perioperative risk factors those predictive of postoperative nausea and vomiting, we fitted the bivariate Dale model to the data set by including all covariates, namely, gender, age, BMI, nonsmoking status, history of migraine and of PONV, type of anesthesia, and duration and type of surgery (using ENT as the reference group). 17,18The bivariate Dale model was used to identify risk factors specifically associated with nausea, vomiting, or both complications. Curr Med Res Opin. NIH Postoperatively, pain VAS characteristics were the following: AUC (59 ± 69 cm × h), mean VAS (1.0 ± 1.1 cm), VASmax (3.9 ± 2.5 cm), the time of maximal VAS, Tmax (8.2 ± 13 h), and PVAS > 3 (6.1 ± 11.2 h). Anaesthesia 1997; 52: 443–9, Dent SJ, Ramachandra V, Stephen CR: Postoperative vomiting: Incidence, analysis and therapeutic measures in 3,000 patients. The time of the peak of VAS (Tmax) occurred at 2.4 ± 8.1 h postoperatively. It is commonly stated that the type of surgery influences the risk of PONV. A nesthesiology 1992; 77: 162–84, Palazzo MG, Strunin L: Anaesthesia and emesis: I. Etiology. Anesthesiol Res Pract. , 11,12,24and more recently Kranke et al. Postoperative nausea and vomiting (PONV) after orthognathic surgery: a retrospective study and literature review. 8, The importance of female gender is well estab-lished and appears as the most important predictor of PONV. In the present study, the overall incidence rate for nausea amounted to 19%, and that for vomiting amounted to 10%. In the present study, patients without and with nausea or vomiting received a similar amount of sufentanil throughout the operative procedure. The study focused on postoperative nausea visual analog scale scores every 4 h and vomiting episodes within 72 h. Both vomiting and retching were considered as emetic events. Meng, … This process was repeated every 2 h for the first 4 h and was continued every 4 h within 72 h on the surgical ward. New concepts and problems like post-discharge nausea and vomiting, new risk factors and new drugs are appearing.
