Racemic Ketamine as an Alternative to Electroconvulsive Therapy for Unipolar Depression: A Randomized, Open-Label, Non-Inferiority Trial (KetECT).

BACKGROUND: Ketamine has emerged as a fast-acting and powerful antidepressant, but no head to head trial has been performed, Here, ketamine is compared with electroconvulsive therapy (ECT), the most effective therapy for depression. METHODS: Hospitalized patients with unipolar depression were randomized (1:1) to thrice-weekly racemic ketamine (0.5 mg/kg) infusions or ECT in a parallel, open-label, non-inferiority study. The primary outcome was remission (Montgomery Åsberg Depression Rating Scale score ≤10). Secondary outcomes included adverse events (AEs), time to remission, and relapse. Treatment sessions (maximum of 12) were administered until remission or maximal effect was achieved. Remitters were followed for 12 months after the final treatment session. RESULTS: In total 186 inpatients were included and received treatment. Among patients receiving ECT, 63% remitted compared with 46% receiving ketamine infusions (P = .026; difference 95% CI 2%, 30%). Both ketamine and ECT required a median of 6 treatment sessions to induce remission. Distinct AEs were associated with each treatment. Serious and long-lasting AEs, including cases of persisting amnesia, were more common with ECT, while treatment-emergent AEs led to more dropouts in the ketamine group. Among remitters, 70% and 63%, with 57 and 61 median days in remission, relapsed within 12 months in the ketamine and ECT groups, respectively (P = .52). CONCLUSION: Remission and cumulative symptom reduction following multiple racemic ketamine infusions in severely ill patients (age 18-85 years) in an authentic clinical setting suggest that ketamine, despite being inferior to ECT, can be a safe and valuable tool in treating unipolar depression.

Mechanical complications after central venous catheterisation in the ultrasound-guided era: a prospective multicentre cohort study.

BACKGROUND: Limited data are available on the incidence of mechanical complications after ultrasound-guided central venous catheterisation. We aimed to determine the incidence of mechanical complications in hospitals where real-time ultrasound guidance is clinical practice for central venous access and to identify variables associated with mechanical complications. METHODS: All central venous catheter insertions in patients ≥16 yr at four emergency care hospitals in Sweden from March 2, 2019 to December 31, 2020 were eligible for inclusion. Every insertion was monitored for complete documentation and occurrence of mechanical complications within 24 h after catheterisation. Multivariable logistic regression analyses were used to determine associations between predefined variables and mechanical complications. RESULTS: In total, 12 667 catheter insertions in 8586 patients were included. The incidence (95% confidence interval [CI]) of mechanical complications was 7.7% (7.3-8.2%), of which 0.4% (0.3-0.5%) were major complications. The multivariable analyses showed that patient BMI <20 kg m-2 (odds ratio 2.69 [95% CI: 1.17-5.62]), male operator gender (3.33 [1.60-7.38]), limited operator experience (3.11 [1.64-5.77]), and increasing number of skin punctures (2.18 [1.59-2.88]) were associated with major mechanical complication. Subclavian vein catheterisation was associated with pneumothorax (5.91 [2.13-17.26]). CONCLUSIONS: The incidence of major mechanical complications is low in hospitals where real-time ultrasound guidance is the standard of care for central venous access. Several variables independently associated with mechanical complications can be used for risk stratification before catheterisation procedures, which might further reduce complication rates.

Intensive care medicine in Europe: perspectives from the European Society of Anaesthesiology and Intensive Care.

BACKGROUND: Anaesthesiology represents a rapidly evolving medical specialty in global healthcare, currently covering advanced peri-operative, pre-hospital and in-hospital critical emergency management (CREM), intensive care medicine (ICM) and pain management. The aim of the European Society of Anaesthesiology and Intensive Care (ESAIC) is to develop and promote a coordinated interdisciplinary and multidisciplinary European network of Anaesthesiology and Intensive Care Medicine (AICM) societies for improvement of patient safety and outcome, and to enhance political and public awareness of the role of anaesthesiologists all over Europe. The ESAIC promotes coordinated interdisciplinary and multidisciplinary care for severely compromised patients, based on the European training requirements (ETR) within the European Union of Medical Specialists (UEMS). METHODS: To define the current situation of AICM in Europe, a survey was sent in April 2019 to the ESAIC Council and the ESAIC National Anaesthesiologists Societies Committee (NASC) members. The survey posed questions regarding the year of foundation, the inclusion of ICM in the society name, and if, and to what extent, various kinds (postoperative, general, specific, mixed) of national ICUs are being run by differing medical specialties. The study data were compiled and analysed by the ESAIC Board, Council and NASC in December 2019. RESULTS AND CONCLUSION: Amongst the 42 European national societies surveyed (41 members of ESAIC-NASC plus Luxembourg), nineteen (45%) also include terms related to critical care medicine or ICM in their names, seven (17%) include terms related to reanimation and three (7%) to resuscitation. In recent years, several national societies revised their names to better reflect their gradual embrace of peri-operative medicine, ICM, CREM and pain management. Approximately 70% of ICU beds in Europe, and 100% in Scandinavia, are being run by anaesthesiologists, the remaining 30% being managed by physicians from other surgical or medical specialties. To emphasise future needs and resources of European AICM, the ESAIC drafted an ICM roadmap in terms of clinical practice, organisation of healthcare, interprofessional and interdisciplinary collaboration, patient safety, outcome and empowerment, professional working conditions, and changes in research, teaching and training required to meet future challenges and expectations.

Fluid deficits during prolonged overnight fasting in young healthy adults.

BACKGROUND: Overnight fasting is often prolonged before scheduled surgery, and the extent of perioperative fluid replacement may influence outcome. In clinical practice, basic requirements are estimated at 1.2-2.0 mL·kg-1 ·h-1 , but there is little contemporary clinical data on what deficits result from complete fasting. This prospective preclinical study was designed to determine total fluid loss during overnight fasting, prolonged during daytime. METHODS: Twenty (10 female) healthy adult volunteers, aged 24 (range 21-46) years, fasted from 22:00 until 16:00, and had their body weight and urine output measured at predefined time intervals. RESULTS: The median (interquartile range) fluid deficits were 0.82 (0.73-1.00) kg, corresponding to 1.26 (1.11-1.41) g·kg-1 ·h-1 for the initial overnight fasting period, 0.59 (0.40-0.70) kg and 0.99 (0.83-1.31) g·kg-1 ·h-1 for the consecutive daytime period, and 1.47 (1.27-1.64) kg and 1.19 (1.05-1.28) g·kg-1 ·h-1 for the total period of fasting. Urine output accounted for 52% of total weight loss and was 36% of the baseline hourly level during the last four-hour period of fasting. CONCLUSIONS: Ten hours of overnight fasting in young adults induces fluid deficits at the lower limit of estimated intervals referred to in clinical practice, and hourly weight loss gradually decreases further during prolonged daytime fasting. These findings indicate that current routine procedures do slightly overestimate fluid deficits resulting from prolonged fasting in perioperative clinical practice.

Single and double pain responses to individually titrated ultra-short laser stimulation in humans.

BACKGROUND: This preclinical study in humans was designed to selectively induce delayed nociceptive pain responses to individually titrated laser stimulation, enabling separate bedside intensity scoring of both immediate and delayed pain. METHODS: Forty-four (fourteen female) healthy volunteers were subjected to repeated nociceptive dermal stimulation in the plantar arc, based on ultra-short carbon dioxide laser with individually titrated energy levels associated with mild pain. RESULTS: Data was analysed in 42 (12 female) subjects, and 29 of them (11 females) consistently reported immediate and delayed pain responses at second-long intervals to each nociceptive stimulus. All single pain responses were delayed and associated with lower levels (p = 0.003) of laser energy density (median 61; IQR 54-71 mJ/mm2), compared with double pain responses (88; 64-110 mJ/mm2). Pain intensity levels associated with either kind of response were readily assessable at bedside. CONCLUSIONS: This study is the first one to show in humans that individually titrated ultra-short pulses of laser stimulation, enabling separate pain intensity scoring of immediate and delayed responses at bedside, can be used to selectively induce and evaluate delayed nociceptive pain, most likely reflecting C-fibre-mediated transmission. These findings might facilitate future research on perception and management of C-fibre-mediated pain in humans.

Bedside vital parameters that indicate early deterioration.

PURPOSE: The purpose of this paper is to determine associations between initially recorded deviations in individual bedside vital parameters that contribute to total Modified Early Warning Score (MEWS) levels 2 or 3 and further clinical deterioration (MEWS level=4). DESIGN/METHODOLOGY/APPROACH: This was a prospective study in which 27,504 vital parameter values, corresponding to a total MEWS level⩾2, belonging to 1,315 adult medical and surgical inpatient patients admitted to a 90-bed study setting at a university hospital, were subjected to binary logistic and COX regression analyses to determine associations between vital parameter values initially corresponding to total MEWS levels 2 or 3 and later deterioration to total MEWS level ⩾4, and to evaluate corresponding time intervals. FINDINGS: Respiratory rate, heart rate and patient age were significantly ( p=0.012, p<0.001 and p=0.028, respectively) associated with further deterioration from a total MEWS level 2, and the heart rate also ( p=0.009) from a total MEWS level 3. Within 24 h from the initially recorded total MEWS levels 2 or 3, 8 and 17 percent of patients, respectively, deteriorated to a total MEWS level=4. Patients initially scoring MEWS 2 had a 27 percent 30-day mortality rate if they later scored MEWS level=4, and 8.7 percent if they did not. PRACTICAL IMPLICATIONS: It is important to observe all patients closely, but especially elderly patients, if total MEWS levels 2 or 3 are tachypnoea and/or tachycardia related. ORIGINALITY/VALUE: Findings might contribute to patient safety by facilitating appropriate clinical and organizational decisions on adequate time spans for early warning scoring in general ward patients.

Prediction of Acute Postoperative Pain from Assessment of Pain Associated With Venous Cannulation.

BACKGROUND: It has previously been reported that venous cannulation-induced pain (VCP) can be used to predict acute postoperative pain after laparoscopic cholecystectomy. Patients rating VCP at ≥2.0 VAS units had 3.4 times higher risk for moderate or severe pain. The purpose of this study was to evaluate if VCP scores of ≥2.0 VAS units are associated with higher risk for acute postoperative pain after various common surgical procedures. METHODS: In a prospective clinical observational study, 600 male and female 18- to 80-year-old patients scheduled for elective surgery were included. The primary outcome measure was the difference in maximum postoperative pain intensity between low responders (VCP < 2.0) and high responders (VCP ≥ 2.0) to VCP. Secondary outcome measures were the difference in proportion of patients with moderate or severe postoperative pain between low and high responders, and potential influence of age, gender, and preoperative habitual pain. RESULTS: Patients scoring VCP ≥2.0 VAS units reported higher acute postoperative pain intensity levels than those scoring VCP <2.0 VAS units (median 3.0 [interquartile range 0.0 to 5.0] vs. 0.2 [interquartile range 0.0 to 4.0], P = 0.001), and also had 1.7 times higher risk for moderate or severe postoperative pain (P = 0.005). Moderate or severe postoperative pain was reported by 38% of patients with VCP scores of ≥2.0 VAS units and by 26% with VCP scores of <2.0 VAS units (P = 0.005). CONCLUSION: Scoring of VCP intensity before surgery, requiring no specific equipment or training, is useful to predict individual risks for moderate or severe postoperative pain, regardless of patient age or gender, in a setting involving different kinds of surgery.

Single Nucleotide Polymorphisms Associated with Pain Sensitivity After Laparoscopic Cholecystectomy.

Objective: To systematically evaluate variations in single-nucleotide polymorphisms within 13 candidate pain genes in patients differing in phenotype characteristics based on a composite measure of pain sensitivity. Methods: In a case-control study, 149 patients scheduled for laparoscopic cholecystectomy were individually categorized according to preoperative pain sensitivity and postoperative pain intensity. Cases (pain group) reported cannulation-induced pain intensity higher than 2.0, together with postoperative pain intensity of 7.0 or higher (visual analog scale [VAS] units), and controls (low-pain group) reported cannulation-induced pain intensity of 2.0 or lower, together with postoperative pain intensity lower than 4.0 (VAS units). Genotyping of exomes was performed in 32 case and 25 control patients compared with respect to variations within 13 candidate pain genes. Results: There were no statistically significant differences in single nucleotide polymorphisms (SNPs) within the candidate genes between the case and control groups, but minor allele SNPs in the ABCB1 and COMT genes were more common in patients with higher levels of pain sensitivity and intensity. Conclusion: In this candidate gene study, based on a composite measure of pain sensitivity, no variations reached statistical significance after correction for multiple testing, most likely due to the large number of markers analyzed and few patients. Nevertheless, the results suggest a possible genetic contribution of single-nucleotide polymorphisms within the ABCB1 and COMT genes in individuals with higher levels of pain sensitivity.

European Society of Anaesthesiology and European Board of Anaesthesiology guidelines for procedural sedation and analgesia in adults.

: Procedural sedation and analgesia (PSA) has become a widespread practice given the increasing demand to relieve anxiety, discomfort and pain during invasive diagnostic and therapeutic procedures. The role of, and credentialing required by, anaesthesiologists and practitioners performing PSA has been debated for years in different guidelines. For this reason, the European Society of Anaesthesiology (ESA) and the European Board of Anaesthesiology have created a taskforce of experts that has been assigned to create an evidence-based guideline and, whenever the evidence was weak, a consensus amongst experts on: the evaluation of adult patients undergoing PSA, the role and competences required for the clinicians to safely perform PSA, the commonly used drugs for PSA, the adverse events that PSA can lead to, the minimum monitoring requirements and post-procedure discharge criteria. A search of the literature from 2003 to 2016 was performed by a professional librarian and the retrieved articles were analysed to allow a critical appraisal according to the Grading of Recommendations Assessment, Development and Evaluation method. The Taskforce selected 2248 articles. Where there was insufficiently clear and concordant evidence on a topic, the Rand Appropriateness Method with three rounds of Delphi voting was used to obtain the highest level of consensus among the taskforce experts.These guidelines contain recommendations on PSA in the adult population. It does not address sedation performed in the ICU or in children and it does not aim to provide a legal statement on how PSA should be performed and by whom. The National Societies of Anaesthesiology and Ministries of Health should use this evidence-based document to help decision-making on how PSA should be performed in their countries. The final draft of the document was available to ESA members via the website for 4 weeks with the facility for them to upload their comments. Comments and suggestions of individual members and national Societies were considered and the guidelines were amended accordingly. The ESA guidelines Committee and ESA board finally approved and ratified it before publication.

Influence of social characteristics on use of paediatric emergency care in Sweden - a questionnaire based study.

BACKGROUND: Parental social characteristics influence the use of emergency departments (ED) in the USA, but less is known about paediatric ED care-seeking in countries with national health insurance. This prospective study was designed to evaluate associations between parental care-seeking and social characteristics, with emphasis on impact of non-native origin, at a paediatric ED in Sweden, a European country providing paediatric healthcare free of charge. METHODS: Parents attending a paediatric ED at a large urban university hospital filled out a questionnaire on social characteristics and reasons for care-seeking. Information on patient characteristics and initial management was obtained from ED registers and patient records. Paediatric ED physicians assessed the medical appropriateness of each patient visit triaged for ED care. RESULTS: In total, 962 patient visits were included. Telephone healthline service before the paediatric ED visit was less often used by non-native parents (63/345 vs. 249/544, p < 0.001). Low-aquity visits, triaged away from the ED, were more common among non-native parents (80/368 vs. 67/555, OR = 1.66; p = 0.018), and among those reporting lower abilities in the Swedish language (23/82 vs. 120/837, OR = 2.66; p = 0.003). Children of non-native parents were more often assessed by physicians not to require ED care (122/335 vs. 261/512, OR = 0.70; p = 0.028). CONCLUSIONS: This study confirms more direct and less urgent use of paediatric ED care by parents of non-native origin or with limited abilities in the Swedish language, proposing that parental social characteristics influence paediatric ED care-seeking, also in a country with healthcare free of charge, and that specific needs of these groups should be better met by prehospital medical services.

The European Board of Anaesthesiology recommendations for safe medication practice: First update.

These European Board of Anaesthesiology (EBA) recommendations for safe medication practice replace the first edition of the EBA recommendations published in 2011. They were updated because evidence from critical incident reporting systems continues to show that medication errors remain a major safety issue in anaesthesia, intensive care, emergency medicine and pain medicine, and there is an ongoing need for relevant up-to-date clinical guidance for practising anaesthesiologists. The recommendations are based on evidence wherever possible, with a focus on patient safety, and are primarily aimed at anaesthesiologists practising in Europe, although many will be applicable elsewhere. They emphasise the importance of correct labelling practice and the value of incident reporting so that lessons can be learned, risks reduced and a safety culture developed.

Diode laser spectroscopy for noninvasive monitoring of oxygen in the lungs of newborn infants.

BACKGROUND: Newborn infants may have pulmonary disorders with abnormal gas distribution, e.g., respiratory distress syndrome. Pulmonary radiography is the clinical routine for diagnosis. Our aim was to investigate a novel noninvasive optical technique for rapid nonradiographic bedside detection of oxygen gas in the lungs of full-term newborn infants. METHODS: Laser spectroscopy was used to measure contents of oxygen gas (at 760 nm) and of water vapor (at 937 nm) in the lungs of 29 healthy newborn full-term infants (birth weight 2,900-3,900 g). The skin above the lungs was illuminated using two low-power diode lasers and diffusely emerging light was detected with a photodiode. RESULTS: Of the total 390 lung measurements performed, clear detection of oxygen gas was recorded in 60%, defined by a signal-to-noise ratio of >3. In all the 29 infants, oxygen was detected. Probe and detector positions for optimal pulmonary gas detection were determined. There were no differences in signal quality with respect to gender, body side or body weight. CONCLUSION: The ability to measure pulmonary oxygen content in healthy full-term neonates with this technique suggests that with further development, the method might be implemented in clinical practice for lung monitoring in neonatal intensive care.

Mandatory early warning scoring--implementation evaluated with a mixed-methods approach.

AIM: The aim of this study was to evaluate adherence to an intervention optimizing in-hospital monitoring practice, by introducing early warning scoring (EWS) of vital parameters. BACKGROUND: Interventions comprising EWS systems reduce in-hospital mortality, but evaluation of adherence to such interventions is required to correctly interpret interventional outcome. METHOD: Adherence was evaluated with a mixed-methods approach. Quantitative data, obtained pre-interventionally (2009) and postinterventionally (2010 and 2011), were used to calculate and compare time intervals between scorings of vital parameters. Semi-structured interviews were used to evaluate the implementation process. RESULTS: We found significant reductions in time intervals between measurements of vital parameters in 2011 compared to 2009. Scorings of vital parameters were repeated within 8 hours in 71-77% of patients scoring total modified EWS levels of 0, 2 or 4. The theme Motivation by clinical relevance and meaningfulness was identified as crucial to the implementation process. CONCLUSION: High adherence to an intervention may be strongly related to nurses' perceived clinical relevance of the intervention.

Measurement of vascular water transport in human subjects using time-resolved pulsed arterial spin labelling.

Most approaches to arterial spin labelling (ASL) data analysis aim to provide a quantitative measure of the cerebral blood flow (CBF). This study, however, focuses on the measurement of the transfer time of blood water through the capillaries to the parenchyma (referred to as the capillary transfer time, CTT) as an alternative parameter to characterise the haemodynamics of the system. The method employed is based on a non-compartmental model, and no measurements need to be added to a common time-resolved ASL experiment. Brownian motion of labelled spins in a potential was described by a one-dimensional general Langevin equation as the starting point, and as a Fokker-Planck differential equation for the averaged distribution of labelled spins at the end point, which takes into account the effects of flow and dispersion of labelled water by the pseudorandom nature of the microvasculature and the transcapillary permeability. Multi-inversion time (multi-TI) ASL data were acquired in 14 healthy subjects on two occasions in a test-retest design, using a pulsed ASL sequence and three-dimensional gradient and spin echo (3D-GRASE) readout. Based on an error analysis to predict the size of a region of interest (ROI) required to obtain reasonably precise parameter estimates, data were analysed in two relatively large ROIs, i.e. the occipital lobe (OC) and the insular cortex (IC). The average values of CTT in OC were 260 ± 60 ms in the first experiment and 270 ± 60 ms in the second experiment. The corresponding IC values were 460 ± 130 ms and 420 ± 139 ms, respectively. Information related to the water transfer time may be important for diagnostics and follow-up of cerebral conditions or diseases characterised by a disrupted blood-brain barrier or disturbed capillary blood flow.

Pediatric emergency department management benefits from appropriate early redirection of nonurgent visits.

AIMS: Overcrowding at pediatric emergency departments (EDs) may result in delayed clinical management and higher risks of medical error. This study was designed to prospectively evaluate what parents of sick children seek emergency care for and how these patients are being assessed and managed. METHODS: Patients aged 0 to 17 years seeking ED care at an urban Swedish university hospital, from 8 AM to 9 PM on 25 consecutive days, were included. Clinical urgency and further level of medical care were determined by experienced nurses based on individual clinical signs and vital parameters. Information on presenting problem, medical priority, gender, age, waiting time, day of week, time of day, and further management was recorded. RESULTS: Among 1057 included children, two thirds were assessed by physicians, whereas one third were referred directly by nurses for other ED (n = 54) or primary care (n = 114), or sent home with medical advice (n = 176), more often during evenings and weekends. Of primarily referred patients, 7.6% returned within 72 hours, and three of them were admitted. Young infants, patients with respiratory or neurological problems, and sicker patients with fever or infections were mainly assessed by physicians, within desired priority time. DISCUSSION: More than one fourth of pediatric ED patients might rapidly, appropriately, and safely be referred for primary care or sent home by experienced pediatric nurses soon after arrival, thereby facilitating management of urgent and more appropriate patients. Evaluations by physicians were primarily required in young infants and for urgent medical conditions demanding qualified pediatric skills.

Impact of professionalism in nursing on in-hospital bedside monitoring practice.

AIM: This article reports a study exploring nursing practice of monitoring in-hospital patients including intra- and interprofessional communication and collaboration. BACKGROUND: Sub-optimal care in general in-hospital wards may lead to admission for intensive care, cardiac arrest, or sudden death. Reasons may include infrequent measurements of vital parameters, insufficient knowledge of their predictive values, and/or sub-optimal use of Medical Emergency Teams. This study was designed to improve understanding of nursing practice and to identify changes required to support nursing staff in improving standards of clinical monitoring practice and patient safety in general in-hospital wards. DESIGN: The study was designed as a qualitative descriptive clinical study, based on method triangulation including structured individual observations and semi-structured individual interviews. METHODS: In the spring of 2009, structured observations and semi-structured interviews of 13 nurses were carried out at a university hospital in Copenhagen, Denmark. The observational notes and interview transcriptions were analysed using content analysis. RESULTS: One theme (Professionalism influences nursing monitoring practice) and two sub-themes (Knowledge and skills and Involvement in clinical practice through reflections) were identified. Three categories (Decision-making, Sharing of knowledge, and Intra- and interprofessional interaction) were found to be associated with the theme, the sub-themes, and with each other. CONCLUSION: Clinical monitoring practice varies considerably between nurses with different individual levels of professionalism. Future initiatives to improve patient safety by further developing professionalism among nurses need to embrace individual and organizational attributes to strengthen their practice of in-hospital patient monitoring and management.

Prospective paired crossover evaluation of potential impact of investigator gender on perceived pain intensity early after acute or scheduled surgery.

BACKGROUND: Postoperative pain is common but often difficult to assess, and there are many potential confounders. Over the last decades, the gender of investigator as well as participant has been found to influence pain perception in both preclinical and clinical studies. However, to our knowledge this has not been studied in various postoperative patients. Objectives of this study were to test the hypotheses that pain intensity levels early after acute or scheduled in- or out-hospital surgery are lower when evaluated by a female investigator, and higher when reported by a female patient. METHODS: In this prospective observational paired crossover study, two investigators of opposite genders independently obtained individually reported pain intensity levels with a visual analogue scale in a mixed cohort of adult postoperative study patients at Skåne University Hospital in Malmö, Sweden. RESULTS: In total, 245 (129 female) study patients were included and then one female excluded. The study patients rated their intensity of postoperative pain lower when evaluated by a female than by a male investigator (P = 0.006), where the male patients constituted the significant difference (P < 0.001). Pain intensity levels did not differ between female and male study patients (P = 0.210). CONCLUSIONS: Main findings of lower pain intensity reported by males to a female than to a male investigator early after surgery in this paired crossover study in mixed postoperative patients, indicate that potential impact of investigator gender on pain perception should be considered and further evaluated in clinical bedside practice.

[Severe Covid-19 comprises a self-amplifying loop of inflammation and coagulopathy]. / Spiral av inflammation och koagulopati bakom svår covid-19.

Severe Covid-19 has a high mortality rate. Vital organ dysfunction results from pathophysiological self-amplifying loops of innate immunological hyperactivation, cytokine release, complement deposition, endothelial damage, and macro- and microvascular thromboembolism. Resulting alveolar exudation and pulmonary capillary thromboembolism lead to ventilation-perfusion mismatch, considered to be a primary cause of death in severe Covid-19. Therapeutic immunomodulation is believed to be safer and more effective during time periods with decreasing viral exposition and increasing inflammation.

[Undergraduate teaching, training and examination of critical emergency management]. / Simulatorträning ger nya läkare självförtroende vid akuta tillstånd.

Current national objectives of Swedish medical schools state that new doctors should be able to independently start rapid and appropriate early treatment and diagnostic assessment in life-threatening situations. Since 2017 more than one thousand senior undergraduate students at Lund University have undergone compulsory five-week training in initial management of potentially reversible medical emergency conditions. The students participate in thematic full-scale simulations of life-threatening bedside challenges associated with chest or abdominal pain, vital organ dysfunction, and major trauma, and also take part in lectures, case-based seminars and clinical emergency practice under individual supervision. The course is concluded by a structured simulation-based holistic examination, designed to test individual abilities of relevant decision-making, rapid and appropriate bedside action, and professional approach.
