The prophylaxis and treatment of postoperative pain to enhance patient comfort has been a primary goal of anesthesiologists for the last decades; however, avoiding postoperative nausea and vomiting (PONV) is, from a patient's perspective, a highly relevant and equally important goal of anesthesia. Recent consensus-based guidelines suggest the assessment of risk factors including female gender, postoperative opioid administration, non-smoking status, a history of PONV or motion sickness, young patient age, longer duration of anesthesia, volatile anesthetics and the type of surgery and reducing the patient's baseline risk (e.g. through the use of regional anesthesia and administration of non-opioid analgesics as part of a multimodal approach). In general, a liberal PONV prophylaxis is encouraged for adult patients and children, which should also be administered when no risk assessment is made. The basis for every adult patient should be a standard prophylaxis with two antiemetics, such as dexamethasone in combination with a 5-HT 3 receptor antagonist. In patients at high risk, this should be supplemented by a third and potentially a fourth antiemetic prophylaxis with a different mechanism of action. A recently published comprehensive Cochrane meta-analysis comparing available antiemetic prophylaxes reported the highest effectiveness to prevent PONV for the NK 1 receptor antagonist aprepitant (relative risk, RR 0.26), followed by ramosetron (RR 0.44), granisetron (RR 0.45), dexamethasone (RR 0.51) and ondansetron (RR 0.55), thereby revising the dogma that every antiemetic is equally effective. Adverse events of antiemetics were generally rare and reported in less than half of the included studies, yielding a low quality of evidence for these end points. In general, combinations of different antiemetics were more effective than single prophylaxes. In children above 3 years of age, the same principles should be applied as in adults. For these patients, there is a high degree of evidence for the combination of dexamethasone and 5‑HT 3 receptor antagonists. When PONV occurs, the consensus guidelines suggest that antiemetics from a class different than given as prophylaxis should be administered. To decrease the incidence of PONV and increase the quality of care, the importance of the implementation of institutional-level guidelines and protocols as well as assessment of PONV prophylaxis and PONV incidence is highly recommended., (© 2021.

Background: One of the prime aims of intensive care is to cure patients or at least to extend life duration, sometimes to the extent of losing quality of life. Palliative care aims to improve the quality of life of patients with life-limiting conditions; however, some patients need both intensive and palliative care. About 5-10% of all deaths in Germany and 20% of all deaths in the USA occur in an intensive care unit (ICU) and many of those as well as other patients may benefit from palliative care consultation. Palliative care consultations are increasingly available for intensive care patients but are still infrequently used., Objectives: We aimed to determine the current situation of palliative patients in ICU settings: what is the impact of palliative care interventions on the quality of care of ICU patients? To what extent is palliative care support at ICUs available and to what extent is it used? Which factors trigger palliative care consultations?, Method: We set out with a search of PubMed, Scopus and other databases in English and on a) the impact of palliative care interventions on the quality of care of ICU patients, b) the utilization of palliative care support in ICUs and c) the factors which trigger palliative care consultations. We included both quantitative and qualitative studies to reflect the views of all parties involved. To emphasize the situation in German-speaking countries we also searched Google Scholar with search terms in German and added those results to the review. Additionally, hand-searched studies in English and in German were included., Results: We screened 695 abstracts and identified 18 relevant articles of which 15 were from the USA and Great Britain, 1 each was from Austria, Germany and Switzerland. Palliative care is a meaningful addition to ICU standard treatment: it can improve quality of care and helps reduce length of stay in an ICU. It is unclear if the reduced length of stay leads to economic benefits; however, the utilization of palliative care is inconsistent and infrequent as is its acceptance among ICU physicians. Trigger factors can be used to improve the integration of palliative care support in ICUs and point out patients' unmet palliative needs., Discussion: Trigger factors can reduce barriers which hold back the integration of palliative care in ICUs. Early integration of palliative care can improve quality of care by offering psychological support to patients and their families and by providing collegial consultation. An ongoing prospective study is investigating the acceptance of trigger factors in the daily routine among ICU physicians in Germany.
