Results were considered to be significant at the 5% critical level (P < 0.05). AUC = area under the curve; BMI = body mass index; NSAID = nonsteroidal antiinflammatory drug; PONV = postoperative nausea and vomiting; PVAS = persistence of VAS pain scores; VAS = visual analog scale; T max = time of the maximal pain score. Duration of surgery was unrelated to outcomes. These could be explained by differences in the physiopathology of the two symptoms. , the time period during which pain VAS was above the critical threshold (h).

Among the 671 patients in the study, 126 (19%) reported one or more episodes of nausea, and 66 patients (10%) suffered one or more emetic episodes during the studied period. Difference in Risk Factors for Postoperative Nausea and Vomiting Anesthesiology (January 2003) Cardiac Arrest during Hospitalization for Delivery in the United States, 1998–2011 During the 72 postoperative hours (table 2), paracetamol was given to all patients with a mean dose of 9.7 ± 6.2 g. Nonsteroidal antiinflammatory drugs were used in 429 patients (64%), and morphine was administered in 324 patients (48%) at a mean dose of 11.4 ± 23.1 mg. Patient-controlled analgesia was prescribed in 20 patients (1.5%) during the study period. Pharmacologic reversal of neuromuscular blocking agents was administered in 19 patients (4%) using neostigmine methylsulfate at a mean dose of 1.5 mg associated with glycopyrrolate (mean dose, 0.4 mg) or atropine (mean dose, 0.3 mg). 28Results of our study are unable to support this statement. Among the 126 patients with nausea, 53 (42%) experienced vomiting.

As seen in table 5, patients undergoing gynecological (P = 0.0082), urological (P = 0.022), abdominal (P = 0.028), and, to a lesser extent, neurologic (P = 0.074), ophthalmologic (P = 0.074), or maxillofacial (P = 0.066) surgery had an increased risk of developing nausea but not vomiting when compared to ENT patients. 30in a randomized control trial found that volatile anesthetics were the leading cause of early postoperative vomiting. Anesth Analg 118 (1): 85 – 113. Nausea, vomiting, and retching frequently complicate recovery from anesthesia. 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… The relationship between patient risk factors and early versus late postoperative emetic symptoms. Studies published to date have used a variety of methodologies that do not permit meaningful conclusions to be drawn. Chemotherapy-induced nausea and vomiting … Several studies have outlined the factors related to an increased incidence of PONV with the aim to target specific patients who might need effective antiemetic prophylaxis. Although risk factors for postoperative nausea are generally assumed as being the same as those for vomiting, the present study made a clear distinction between the two events, considered as two different end points. Some risk factors were predictive of both nausea and vomiting (female gender, nonsmoking status, and general anesthesia). NSAID = nonsteroidal antiinflammatory drug. J Clin Anesth 2000; 12: 402–8, Dale JR: Global cross-ratio models for bivariate, discrete, ordered responses. Statistical calculations were carried out by means of the SAS package (SAS Institute, Cary, NC; version 8 for Windows), always using all data available. 2020 Oct 28;9(11):3477. doi: 10.3390/jcm9113477. BMC Anesthesiol. 14, As recently stated by Tramèr, 14,35“more precise quantification of PONV incidence will come from studies where nausea and vomiting are separate endpoints, and the cumulative incidence of nausea and vomiting is reported at different time points.” The methodological issue used in this survey considered these recommendations. 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). A sample of 671 surgical patients with complete case report forms was included in the study. , ENT and ophthalmology, known to maximize the incidence of PONV. 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. Conversely, among the 66 patients with vomiting, 53 (80%) had nausea. The same argument applies for nonsmokers who are more likely to develop the complications than smokers: nausea (OR = 2.41; 1.26–4.60) and vomiting (OR = 3.0; 1.35–6.71). 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. 9 NOV 2018. Nausea alone occurred in 73 (11%) patients, vomiting alone occurred in 13 (2%) patients, 53 (8%) patients suffered from both nausea and vomiting, while 532 (79%) were free from the complications. Thus, even when accounting for covariates, the two outcomes remained strongly dependent on each other (i.e. Table 2. In that respect, the bivariate Dale model is an interesting alternative to classic approaches, which apply logistic regression to each outcome separately and hence ignore the dependence structure of nausea and vomiting. The predictive effect of risk factors was controlled for postoperative pain and analgesic drugs. In the subsequent study, nausea and vomiting were considered as the two outcomes of interest. 34Nausea is not always followed by retching or vomiting.
