Br J Anaesth 1992; 69(suppl 1): 24S–32S, Kortilla K: The study of postoperative nausea and vomiting. Postoperative nausea and vomiting (PONV) is a patient-important outcome; patients … [Article in English, Spanish] Veiga-Gil L(1), Pueyo J(2), López-Olaondo L(2). 2014. COVID-19 is an emerging, rapidly evolving situation. The patients preoperative characteristics are summarized in table 1. Opioids were antagonized in six patients (1.2%) using naloxone. In the present prospective investigation, we studied a fairly large number of surgical inpatients. In studies with these drawbacks, the true influence of the investigated risk factor remained unclear. History of migraine and type of surgery were mainly responsible for nausea but not for vomiting. All drugs given for pain relief were documented. 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. Results were expressed as mean ± SD for quantitative variables and as proportions for categorical factors. Distribution of the Patients with Nausea and Vomiting According to Type of Surgery. 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). Many studies have sought to determine risk factors … White PF, Sacan O, Nuangchamnong N, Sun T, Eng MR. Anesth Analg. 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. 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. There are a number of risk factors for PONV. Br J Anaesth 1992; 69(suppl 1): 2S–19S, Camu F, Lauwers MH, Verbessem D: Incidence and aetiology of postoperative nausea and vomiting. The authors designed a prospective study to identify and differentiate the risk factors for postoperative nausea and vomiting in various surgical populations in a clinical audit setting. 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). Br J Anaesth 1997; 78: 256–9, Eriksson H, Kortilla K: Prevention of postoperative pain and emesis. Duration of anesthesia (general and locoregional) was 100 ± 66 min. Kim JH, Lim MS, Choi JW, Kim H, Kwon YS, Lee JJ. Curr Opin Anaesthesiol 1997; 10: 438–44, Sneyd JR, Carr A, Byrom WD, Bilski AJT: A meta-analysis of nausea and vomiting following maintenance of anaesthesia with propofol or inhalational agents. 2020 Sep 15;2020:9792170. doi: 10.1155/2020/9792170. J Clin Anesth 1999; 11: 583–9, Boogaerts JG, Bardiau FM, Seidel L, Albert A, Ickx BE: Tropisetron in the prevention of postoperative nausea and vomiting. Positive coefficients are associated with an increased risk of developing the complication (OR > 1). The modern era in PONV risk factor research began in the early 1990s, with publication of the first studies that attempted t… , ENT and ophthalmology, known to maximize the incidence of PONV. NIH The distribution of patients according to postoperative nausea and vomiting is given in table 3. 1–13It is assumed that PONV has a multifactorial origin, such as patient-related factors (e.g. The incidence of PONV after administration of various anesthetic agents reported by different authors cannot be compared since each group of authors used different criteria and different population groups. Duration of surgery was unrelated to outcomes. Results of the Application of the Bivariate Dale Model to Nausea and Vomiting Data. The score constructed by Apfel et al. 17,18The bivariate Dale model was used to identify risk factors specifically associated with nausea, vomiting, or both complications. Studies published to date have used a variety of methodologies that do not permit meaningful conclusions to be drawn. Assessing Risk Factors for Postoperative Nausea and Vomiting: A Retrospective Study in Patients Undergoing Retromastoid Craniectomy With Microvascular Decompression of Cranial Nerves. Several risk factors are incriminated in their occurrence. Details of anesthesia and surgery, as well as all postoperative events, were recorded on the same case report form that followed the patient during the survey. Background: /st> In assessing a patient's risk for postoperative nausea and vomiting (PONV), it is important to know which risk factors are independent predictors, and which factors are not relevant … 1–3,6Our data reflected a casual impact of surgical procedures on nausea alone, notably gynecology, and abdominal surgery with the exception of urology that increased both nausea and vomiting. 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. Vomiting is a complex reflex under the control of two functionally distinct medullar centers: the vomiting center in the dorsal portion of the lateral reticular formation and the chemoreceptor trigger zone in the area postrema of the floor of the fourth ventricle. Background. 15These measurements are in accordance with the studies conducted by Cohen et al. 36Furthermore, nausea intensity was assessed using a VAS device as a secondary end point. 34Nausea is not always followed by retching or vomiting. Br J Anaesth 1993; 70: 135–40, Koivuranta M, Läärä E, Snare L, Alahuhta S: A survey of postoperative nausea and vomiting. Anti-dopaminergic drug could help ease postoperative nausea and vomiting in high-risk patents. Prior to the start of the study, local Ethics Committee (Charleroi, Belgium) approval was obtained, and written informed consent was given by all patients. Nausea was not assessed while the patient was asleep. Among perioperative related factors, general anesthesia influenced the probability of nausea and vomiting, but there was no direct association between the duration of anesthesia and the incidence of PONV, as demonstrated by Sinclair et al. 13Administration of propofol for anesthesia induction and/or maintenance did not reduce the risk for early nausea or delayed vomiting in our surgical population. Undesirable Postoperative Anesthesia Outcomes at Two National Referral Hospitals: A Cross-Sectional Study in Eritrea. They can be divided into patient factors, surgical factors, and anaesthetic factors. This literature shows that female gender post-puberty, nonsmoking status, history of PONV or motion sickness, childhood after infancy and younger adulthood, increasing duration of surgery, and use of volatile anesthetics, nitrous oxide, large-dose neostigmine, or intraoperative or postoperative opioids are well established PONV risk factors. Can Anaesth Soc J 1984; 31: 178–87, Lerman J: Surgical and patient factors involved in postoperative nausea and vomiting. A clear relationship can be seen between the two outcomes and type of surgery. 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. , female gender, history of motion sickness, or PONV), anesthetic factors (e.g. 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… Acta Anaesthesiol Scand 2001; 45: 160–6, Tramèr M, Moore A, McQuay H: Propofol anesthesia and post-operative nausea and vomiting: Quantitative systematic review of randomized controlled studies.
