What was the operation? Metoclopramide use has been associated with extrapyramidal and sedative side-effects. For Permissions, please email: journals.permissions@oup.com, Copyright © 2020 The British Journal of Anaesthesia Ltd. Aprepitant is not associated with QTc prolongation or sedative effects, but its high cost limits its use to high-risk patients. POST OPERATIVE NAUSEA AND VOMITING Dr Kiran Rajagopal DA DNB. Make the changes yourself here! At low doses, dexamethasone is not only effective against PONV but also against post-surgical pain and fatigue. Published by Oxford University Press on behalf of the British Journal of Anaesthesia. Some risk factors, like gynaecological surgery, are associated with a high incidence of PONV. Multifactorial scores are significantly more accurate at predicting the patient's risk of PONV than single risk factors like surgical site, history of PONV, or history of motion sickness (ROC-AUC=0.68, 0.53, and 0.58, respectively). Use the information in this article to help you with the answers. Consider the following questions during your assessment of the patient: In addition, it is important to be aware of alternative causes of nausea and vomiting in the post-operative patient, such as infection, gastrointestinal causes (post-operative ileus, bowel obstruction), metabolic causes (hypercalcaemia, uraemia, DKA), medication (antibiotics, opioids), CNS causes (raised ICP), or psychiatric causes (anxiety). 5-Hydroxytrytamine type 3 (5-HT3) receptor antagonists, and specifically ondansetron, are the most commonly used antiemetics for both prophylaxis and rescue treatment for PONV. There is insufficient evidence to conclude that neostigmine increases the risk of PONV. The NTS triggers vomiting by stimulating the rostral nucleus, the nucleus ambiguous, the ventral respiratory group, and the dorsal motor nucleus of the vagus. Untreated, one third will have postoperative nausea, vomiting, or both. The physiology of PONV is complex and not perfectly understood. No randomized controlled trials and few multivariable analyses have investigated the effect of general vs locoregional anaesthesia on PONV, and ORs associated with general anaesthesia range from 1.3 to 10.6. Nausea and vomiting Table 1. The D2 receptor antagonist droperidol has a short plasma half-life and should therefore be given towards the end of surgery. Multiple neurotransmitter pathways are implicated in the physiology of nausea and vomiting. The three simplified risk scores showed favourable calibration curves and discrimination properties even in external validations of the models, which indicates that the scores can be clinically useful. Postoperative nausea and vomiting remains a common cause of morbidity. Postoperative nausea and vomiting (PONV) is an enormous problem for patients recovering after surgery. PONV can be triggered by several perioperative stimuli, including opioids, volatile anaesthetics, anxiety, adverse drug reactions, and motion. Although the available antiemetic drugs have been proven safe in clinical trials, no agent is without its side-effects. Vomiting is the forceful expulsion of upper gastrointestinal contents via the mouth, brought about by powerful sustained contraction of the abdominal muscles. Postoperative nausea and vomiting is the nausea and vomiting symptoms which occurred after a surgery, medicines intake or anaesthesia usage. First, the patient's baseline risk should be calculated using the Apfel simplified risk score for adults or the POVOC score for children. To reduce the incidence of PONV without increasing the risk of unnecessary side-effects, antiemetic prophylactic regimens should be tailored to the patients most likely to experience PONV. dexamethasone), and dopamine antagonists (e.g. However, there is currently little evidence to support this theory. A planned multimodal approach should be opted consisting of nonpharmacologic and pharmacologic prophylaxis along with interventions to reduce the baseline risks. An alternative to pharmacological treatment may be acustimulation of P6, which has demonstrated some efficacy in reducing PONV without major side-effects.7 Some uncertainties remain regarding the type of stimulation to apply, the timing, and the target population. TIVA, antiemetic drugs), whereas patients at high risk can receive three or four interventions. By visiting this site you agree to the foregoing terms and conditions. It has an incidence of about 25% in adults, with a published range of 5-75%.

For adult patients, age is a statistically, though not clinically, relevant risk factor, with the incidence of PONV decreasing as patients age. Ondansetron is the most commonly used drug for rescue treatment. Nausea, vomiting, and retching frequently complicate recovery from anesthesia. OR) of each hypothesized risk factor as a coefficient. Other first-line prophylactic antiemetics include dexamethasone, droperidol, and aprepitant for high-risk patients. Postoperative nausea and vomiting (PONV) is defined as any nausea, retching, or vomiting occurring during the first 24–48 h after surgery in inpatients. The independent risk factors for POV are the duration of surgery ≥30 min, age ≥3 yr, strabismus surgery, and history of POV in the child or of PONV in his/her relatives. A number of neurotransmitters are involved in the control of vomiting. • PONV - two of the most common and unpleasant side effects following anaesthesia and surgery • Incidence of nausea - 22% to 38% Incidence of vomiting - … The vomiting centre receives input from the chemoreceptor trigger zone, gastro-intestinal tract, vestibular system and higher cortical structures (such as sight, smell and pain). PONV risk factors have been described in the literature since the late 1800s (20). Post-operative nausea . Generally, uncomplicated PONV rarely goes beyond 24 hours post-operatively. In addition, it is important to be aware of alternative causes of nausea and vomiting in the post-operative patient, such as infection, gastrointestinal causes (post-operative ileus, bowel obstruction), metabolic causes (hypercalcaemia, uraemia, DKA), medication (antibiotics, opioids), CNS causes (raised ICP), or psychiatric causes (anxiety). However, large prospective trials that used multivariable analysis to identify PONV risk factors found no such associations. Try again to score 100%. 2. 1). If in any doubt, an ABCDE approach should be taken. Is it likely to cause PONV? Dimenhydrinate is an antihistamine like promethazine and cyclizine. If this is not the case, PONV can be treated with a different class of antiemetics than those used prophylactically. Transdermal scopolamine is a cholinergic antagonist typically used to treat motion sickness. As previously mentioned, antiemetic drugs like ondansetron, dexamethasone, and droperidol are similarly effective, each reducing the patient's risk by 25%.2 Because they work on different receptor classes, their effects are additive.2 Thus, patients at low-to-moderate risk can be given one or two interventions (e.g. Over half of all surgery patients experience nausea and vomiting, some immediately after surgery, and others once they get home and are recovering there. headache for ondansetron) to potentially severe (e.g. Which anaesthetic agents/post operative drugs have been used? In fact, only 20–30% of the patients will respond to any currently available antiemetic. Revisions: 40. Apfel et al. Consider these carefully in the assessment of these patients. use of volatile anaesthetics). For example, in the ambulatory care … PONV is one of the most common causes of patient dissatisfaction after anaesthesia, with reported incidences of 30% in all post-surgical patients and up to 80% in high-risk patients.
