Physician utilization in prehospital emergency medical services in Europe: an overview and comparison. / Visión general y comparación de la presencia de médicos en los servicios de emergencias médicas prehospitalarios en Europa.

OBJECTIVES: National and regional systems for emergency medical care provision may differ greatly. We sought to determine whether or not physicians are utilized in prehospital care and to what extent they are present in differentEuropean countries. MATERIAL AND METHODS: We collected information on 32 European countries by reviewing publications and sending questionnaires to authors of relevant articles as well as to officials of ministries of health (or equivalent), representatives of national societies in emergency medicine, or well-known experts in the specialty. RESULTS: Thirty of the 32 of European countries we studied (94%) employ physicians in prehospital emergency medical services. In 17 of the 32 (53%), general practitioners also participate in prehospital emergency care. Emergency system models were described as Franco-German in 27 countries (84%), as hybrid in 17 (53%), and as Anglo-American in 14 (44%). Multiple models were present simultaneously in 17 countries (53%). We were able to differentiate between national prehospital emergency systems with a novel classification based on tiers reflecting the degree of physician utilization in the countries. We also grouped the national systems by average population and area served. CONCLUSION: There are notable differences in system designs and intensity of physician utilization between different geographic areas, countries, and regions in Europe. Several archetypal models (Franco-German, hybrid, and Anglo- American) exist simultaneously across Europe.

OBJETIVO: Los sistemas nacionales y regionales de prestación de atención médica a las emergencias pueden diferir mucho entre sí. Se buscó dilucidar la presencia de médicos en la atención prehospitalaria y su implantación en los diferentes países europeos. METODO: Se analizaron los datos de 32 países europeos recogidos mediante la revisión de artículos publicados y a través de cuestionarios enviados a los autores de artículos científicos pertinentes, funcionarios del ministerio de sanidad (o equivalente), representantes de sociedades nacionales de medicina de urgencias o expertos reconocidos en medicina de urgencias. RESULTADOS: Treinta de los 32 países europeos investigados (94%) disponen de médicos en los servicios de emergencias prehospitalarios. En 17 de 32 (53%), los médicos generalistas también participan en la atención a las emergencias prehospitalarias. Los modelos de los sistemas de emergencias médicas (SEM) se describieron como francoalemanes en 27 países (84%), híbridos en 17 (53%) o angloamericanos en 14 (44%). En 17 países (53%), coexistían diferentes modelos. Utilizando una nueva forma de clasificación por niveles, basada en la población media y el área atendida por el SEM prehospitalario, se pudieron diferenciar claramente los diferentes modelos existentes. CONCLUSIONES: Se observan notables diferencias en los diseños de los SEM y en la presencia de los médicos entre las diferentes áreas geográficas, países y regiones de Europa. Coexisten varios modelos (francoalemán, híbrido y angloamericano), algunos simultáneamente, en los diferentes países.

Prolonged sedation with sevoflurane in comparison to intravenous sedation in critically ill patients - A randomized controlled trial.

BACKGROUND: Volatile anesthetics are used more commonly for sedation in the intensive-care-unit (ICU). However, evidence for long-term use remains low. We therefore conducted a randomized-controlled trial comparing sevoflurane with intravenous sedation with particular focus on efficacy and safety. METHODS: In this prospective, randomized-controlled phase-IIb monocentric clinical-trial ICU patients requiring at least 48 h of sedation were randomized to receive sevoflurane (S) or propofol/midazolam (P). Sedation quality was monitored using the Richmond-Agitation-Sedation-Scale. Following termination of sedation, the time to spontaneous breathing and extubation, opioid consumption, hemodynamics, ICU and hospital length of stay (LOS) and adverse events were recorded. RESULTS: 79 patients were eligible to randomization. Sedation quality was comparable between sevoflurane (n = 39) and propofol (n = 40). However, the use of sevoflurane lead to a reduction in time to spontaneous breathing (26 min vs. 375 min, P < 0.001). Patients sedated with propofol had lower opioid requirements (remifentanil:400 µg/h vs. 500 µg/h, P = 0.007; sufentanil:40 µg/h vs. 30 µg/h, P = 0.007) while hemodynamics, LOS or the occurrence of adverse events did not differ. CONCLUSION: ICU patients sedated with sevoflurane >48 h may return to spontaneous breathing faster, while the quality of sedation is comparable to a propofol-based sedation regime. Sevoflurane might be considered to be safe for long-term sedation in this patient population, while being non-inferior compared to propofol.

[Functional and morphological disorders of taste and olfaction in COVID-19 patients]. / Funktionelle und morphologische Geschmacks- und Geruchsstörungen bei COVID-19-Patienten.

OBJECTIVE: This study aimed to test the prevalence and evolution of acute olfactory and gustatory functional impairment and their morphologic correlates in COVID-19 patients who require hospitalization due to COVID-19-related respiratory conditions. METHODS: Included were 53 consecutive hospitalized patients (23 males, 30 females; age 42.54 ± 10.95 years) with an RT-PCR-confirmed COVID-19 diagnosis. Patients were examined twice: just after hospital discharge and 4-6 weeks later. Electrogustometric (EGM) thresholds at the tongue area supplied by the chorda tympani, at the soft palate, and in the region of the vallate papillae were recorded bilaterally. Olfaction was examined by Sniffin' sticks (Burghardt GmbH, Wedel, Germany). The patients' nasal and oral mucosa (fungiform papillae, fpap) were examined by contact endoscopy. Findings were compared to those of 53 healthy individuals matched for sex and age (23 males, 30 females; age 42.90 ± 10.64 years). RESULTS: EGM thresholds in patients were significantly higher than those of healthy subjects at both timepoints. EGM thresholds at the second measurement were significantly lower than those at the first measurement. Accordingly, patient-reported gustatory outcomes were improved at the second measurement. The same pattern was found using Sniffin' sticks. Significant alterations in form and vascularization of fPap were detected in patients, especially at the first instance. Interestingly we did not observe any significant changes in the morphology and vascularization of nasal mucosa. CONCLUSION: COVID-19 affects both gustatory and olfactory functions. In parallel, it also affects the structure and vascularization of both nasal and oral mucosa, albeit the nasal mucosa to a much lesser, non-significant extent. Our findings suggest that COVID-19 may cause a mild to profound neuropathy of multiple cranial nerves.

Google Trends for Pain Search Terms in the World's Most Populated Regions Before and After the First Recorded COVID-19 Case: Infodemiological Study.

BACKGROUND: Web-based analysis of search queries has become a very useful method in various academic fields for understanding timely and regional differences in the public interest in certain terms and concepts. Particularly in health and medical research, Google Trends has been increasingly used over the last decade. OBJECTIVE: This study aimed to assess the search activity of pain-related parameters on Google Trends from among the most populated regions worldwide over a 3-year period from before the report of the first confirmed COVID-19 cases in these regions (January 2018) until December 2020. METHODS: Search terms from the following regions were used for the analysis: India, China, Europe, the United States, Brazil, Pakistan, and Indonesia. In total, 24 expressions of pain location were assessed. Search terms were extracted using the local language of the respective country. Python scripts were used for data mining. All statistical calculations were performed through exploratory data analysis and nonparametric Mann-Whitney U tests. RESULTS: Although the overall search activity for pain-related terms increased, apart from pain entities such as headache, chest pain, and sore throat, we observed discordant search activity. Among the most populous regions, pain-related search parameters for shoulder, abdominal, and chest pain, headache, and toothache differed significantly before and after the first officially confirmed COVID-19 cases (for all, P<.001). In addition, we observed a heterogenous, marked increase or reduction in pain-related search parameters among the most populated regions. CONCLUSIONS: As internet searches are a surrogate for public interest, we assume that our data are indicative of an increased incidence of pain after the onset of the COVID-19 pandemic. However, as these increased incidences vary across geographical and anatomical locations, our findings could potentially facilitate the development of specific strategies to support the most affected groups.

Electrogustometry: Normative data for stimulus duration, tongue site and age decline.

OBJECTIVES: Our primary goal was to evaluate the effect of stimulus duration on electrogustometry (EGM) thresholds. Additionally, we sought to evaluate any sex-related influences and compare the above results to those of taste strips. DESIGN: Electrogustometry thresholds of various stimulus durations (0.5, 1.0, 1.5 and 2.0 seconds) were measured in 212 non-smokers (age range: 10-80 years, divided into eight age-groups) without self-reported gustatory impairment. Furthermore, taste strips chemogustometry measurements in 132 participants were performed. SETTING: Tertiary referral medical centre. PARTICIPANTS: 212 non-smokers, divided into eight age-groups participated in the study. MAIN OUTCOME MEASURES: Electrogustometry thresholds and taste strips, duration of EGM stimuli. RESULTS: Electrogustometry thresholds increased progressively with age and with stimulus duration from 0.5 to 2 seconds. This pattern was consistent in all six anatomic areas, irrespective of sex. In contrast, when using chemogustometry, no age- or sex-related differences were observed. CONCLUSIONS: Electrogustometry-threshold values increase progressively with age and with stimulus duration. Therefore, we recommend documenting stimulus duration in the future EGM recordings as it may significantly affect EGM amplitude threshold values.

Influence of personalised music and ice-tea options on post-operative well-being in the post anaesthesia care unit after general or regional anaesthesia. A pre-post-analysis by means of a questionnaire.

OBJECTIVES: Assessment whether patients' wellbeing and disturbances in the post anaesthesia care unit could be influenced by the consecutive introduction of initially personalised music and then additionally various drink options. DESIGN/SETTING: A pre-post-analysis by means of an anonymised survey with a validated questionnaire in a university hospital in central Europe. MAIN OUTCOME MEASURES: Wellbeing and disturbances in the post anaesthesia care unit. RESULTS: Patients' most frequently reported early postsurgical disturbances (n = 1335) were lack of wellbeing, dry mouth and pain in the surgical area. Reported rates of clinically relevant wellbeing were not statistically different in patients that were offered personalised music (46.5%) or additionally ice-tea (50.6%). No correlation could be found between wellbeing or physical discomfort and headphones or when ice-tea were offered. CONCLUSION: After a decade of increased efforts to improve patients' wellbeing in the postanaesthesia care unit we could not show further influence on it by the introduction of personalised music and ice-tea. We see the need for a more differentiated focus on this topic and the need for exploratory studies on patient perception. The most frequent claims were related to lack of wellbeing, pain in the surgical area and a dry mouth.
