RESUMEN
BACKGROUND: Anaesthesiologists deliver an increasing amount of patient care and often work long hours in operating theatres and intensive care units, with frequent on-calls and insufficient rest in between. In the long term, this will negatively influence mental and physical health and well being. As fatigue becomes more prevalent, this has predictable implications for patient safety and clinical effectiveness. 1. OBJECTIVE: This study aimed to evaluate the prevalence, severity, causes and implications of work-related fatigue amongst specialist anaesthesiologists. DESIGN: An online survey of specialist anaesthesiologists. PARTICIPANTS: The survey was sent to anaesthesiologists in 42 European countries by electronic mail. MAIN OUTCOME MEASURES: Responses from a 36-item online survey assessed work-related fatigue and its impact on anaesthesiologists in European countries. RESULTS: Work-related fatigue was experienced in 91.6% of the 1508 respondents from 32 European countries. Fatigue was caused by their working patterns, clinical and nonclinical workloads, staffing issues and excessive work hours. Over 70% reported that work-related fatigue negatively impacted on their physical and mental health, emotional well being and safe commuting. Most respondents did not feel supported by their organisation to maintain good health and well being. CONCLUSION: Work-related fatigue is a significant and widespread problem amongst anaesthesiologists. More education and increased awareness of fatigue and its adverse effects on patient safety, staff well being and physical and mental health are needed. Departments should ensure that their rotas and job plans comply with the European Working Time Directive (EWTD) and introduce a fatigue risk management system to mitigate the effects of fatigue.

The quadratus lumborum block is a technique that is not widely applied in abdominal surgery. The influence of the mode of anesthesia on the outcome of polymorbid patients is a controversial issue in the medical literature. We report a case in which we performed a quadratus lumborum block type 2 on a woman who was admitted to Riga's 1st hospital in need of gastrostomy, due to difficulty swallowing solid foods and liquids caused by hypopharynx carcinoma. On account of the patient's difficult airway, general anesthesia was deemed unsafe for the patient, with a risk of patient death. Percutaneous gastrostomy tube placement under a quadratus lumborum block type 2 was performed successfully.

BACKGROUND: Fluid-induced hypervolemia may stimulate the release of natriuretic peptides and cause degradation (shedding) of the endothelial glycocalyx layer. Sevoflurane is believed to protect the glycocalyx, but the importance of using sevoflurane to prevent shedding during routine surgery is unclear. METHODS: The plasma concentrations of brain natriuretic peptide and two biomarkers of glycocalyx shedding, syndecan-1, and heparan sulfate, were measured in 26 patients randomized to receive general anesthesia with sevoflurane or propofol during open abdominal hysterectomy. The fluid therapy consisted of 25 mL/kg (approximately 2 L) of Ringer´s lactate over 30 minutes. Blood hemoglobin and plasma albumin were used to indicate plasma volume expansion and capillary leakage. RESULTS: The plasma concentrations of brain natriuretic peptide and shedding products showed low levels throughout the surgery (median brain natriuretic peptide, 21 ng/L; syndecan-1, 12.9 ng/mL; and heparan sulfate, 6.5 µg/mL), but the heparan sulfate concentration increased 2 hours post-operatively (to 17.3 µg/mL, P < .005). No differences were noted between the propofol and sevoflurane groups in any of the measured parameters. Albumin was apparently recruited to the bloodstream during the first 20 minutes, when the intravascular retention of infused fluid was almost 100%. The urine flow was <1 mL/min, despite the vigorous volume loading. CONCLUSIONS: No relevant elevations of brain natriuretic peptide or degradation products of the glycocalyx layer were observed when hypervolemia was induced during open abdominal hysterectomy performed with sevoflurane or propofol anesthesia. Plasma volume expansion from Ringer´s lactate was pronounced.

: The change from time-based to competency-based medical education has been driven by society's requirement for greater accountability of medical practitioners and those who train them. The European Society of Anaesthesiology and European Section/Board of Anaesthesiology (Anaesthesiology Section of the European Union Medical Specialists) endorse the general principles of competency-based medical education and training (CBMET) outlined by the international competency-based medical education collaborators. A CBMET curriculum is built on unambiguously defined learning objectives, each of which offers a measurable outcome, amenable to assessment using valid and reliable tools. The European training requirements laid out by the European Board of Anaesthesiology define four 'Generic Competences', namely expert clinician, professional leader, academic scholar and inspired humanitarian. A CBMET programme should clearly document core competencies, defined end-points, proficiency standards, practical descriptions of teaching and assessment practices and an assessment plan. The assessment plan should balance the need to provide regular, multidimensional formative feedback to the trainee with the need to inform high stakes decisions. A trainee who has not achieved a proficiency standard should be provided with an individualised training plan to address specific competencies or deficits. Programme formats will inevitably differ given the constraints of scale and resource that apply in different settings. The resources necessary to develop and maintain a CBMET programme in anaesthesiology include human capital, access to clinical learning opportunities, information technology and physical infrastructure dedicated to training and education. Simulation facilities and faculty development require specific attention. Reflective practice is an important programme element that supports wellbeing, resilience and achievement of professional goals. CBMET programmes should enable establishment of a culture of lifelong learning for the anaesthesiology community.

: An important variability of anaesthetic standards of care was discovered in the obstetric departments of many European Union countries. After discussing this issue in various meetings of the European Society of Anaesthesiology (ESA) board and its obstetric subcommittee, European Board of Anaesthesiology of the European Union of Medical Specialists (EBA-UEMS) executive members, ESA obstetric subcommittee members and European experts in obstetric anaesthesiology have participated in the elaboration of this document. This experts' opinion is focused mainly on obstetric patients and safety concerns in terms of minimum standards of practice. An initial bibliographical search was performed in medical databases and general literature, searching for obstetric anaesthesiology standards to select the most important safety issues. After the initial presentation of the project during EBA-UEMS and ESA obstetric subcommittee meetings, participants were asked to review the document; several rounds of revisions were performed by the experts, to reach a common opinion concerning the topics considered central to patient safety in the obstetric setting. After three rounds of revision, a consensus was reached and is presented in this document, which includes the list of topics considered relevant by the involved areas, and the respective recommendations. These recommendations covered some EBA-UEMS strategic key areas, in addition to several clinical aspects of common obstetric practice.

BACKGROUND: Surgery with and without hypervolaemia may cause shedding (breakdown) of the endothelial glycocalyx layer, but the severity of this problem is unclear. METHODS: In this preliminary report of a larger clinical trial, the plasma and urine concentrations of three biomarkers of glycocalyx shedding (syndecan-1, hyaluronic acid and heparan sulfate) were measured in seven patients before, during, and after open hysterectomy. The fluid therapy consisted of 25 ml/kg (approximately 2 l) of Ringer's lactate, which was infused over 30 min when the surgery started. The resulting plasma volume expansion at the end of the infusion was estimated from the haemodilution. RESULTS: The mean plasma concentration of syndecan-1 was 21.7 ng/ml before surgery and averaged 19.7 ng/ml during and after the surgery. The plasma concentration of hyaluronic acid decreased from 38.0 to 27.7 ng/ml (P < 0.05), while heparan sulfate increased from 3.4 to 5.5 µg/ml (P < 0.05). The urine concentrations of syndecan-1 decreased significantly, while they increased for hyaluronic acid and heparan sulfate. Despite the vigorous fluid load, the urine flow did not exceed 1 ml/min. CONCLUSIONS: No clear evidence was found for shedding of the endothelial glycocalyx layer when 2 l of Ringer's lactate was infused over 30 min during abdominal hysterectomy. Urine analyses yielded patterns of changes that differed from those in plasma. TRIAL REGISTRATION: ISRCTN81005631 . Registered May 17, 2016.

BACKGROUND: Current obstructive sleep apnea treatment relies on manual PAP titration, but it has limitations. Complex interactions during titration and variations in SpO2 data accuracy pose challenges. Patients with co-occurring chronic hypercapnia may require precise oxygen titration. To address these issues, we propose a Clinical Decision Support System using Markov decision processes. METHODS: This study, compliant with data protection laws, focused on adults with OSA-induced hypoxemia utilizing supplemental oxygen and CPAP/BiPAP therapy. PAP titration, conducted over one night, involved vigilant monitoring of vital signs and physiological parameters. Adjustments to CPAP pressure, potential BiLevel transitions, and supplemental oxygen were precisely guided by patient metrics. Markov decision processes outlined three treatment actions for disorder management, incorporating expert medical insights. RESULTS: In our study involving 14 OSA patients (average age: 63 years, 27% females, BMI 41 kg m-2), significant improvements were observed in key health parameters after manual titration. The initial AHI of 61.8 events per hour significantly decreased to an average of 18.0 events per hour after PAP and oxygen titration (p < 0.0001), indicating a substantial reduction in sleep-disordered breathing severity. Concurrently, SpO2 levels increased significantly from an average of 79.7% before titration to 89.1% after titration (p < 0.0003). Pearson correlation coefficients demonstrated aggravation of hypercapnia in 50% of patients (N = 5) with initial pCO2 < 55 mmHg during the increase in CPAP pressure. However, transitioning to BiPAP exhibited a reduction in pCO2 levels, showcasing its efficacy in addressing hypercapnia. Simultaneously, BiPAP therapy correlated with a substantial increase in SpO2, underscoring its positive impact on oxygenation in OSA patients. Markov Decision Process analysis demonstrated realistic patient behavior during stable night conditions, emphasizing minimal apnea and good toleration to high CPAP pressure. CONCLUSIONS: The development of a framework for Markov decision processes of PAP and oxygen titration algorithms holds promise for providing algorithms for improving pCO2 and SpO2 values. While challenges remain, including the need for high-quality data, the potential benefits in terms of patient management and care optimization are substantial, and this approach represents an exciting frontier in the realm of telemedicine and respiratory healthcare.
RESUMEN
BACKGROUND AND OBJECTIVE: The plasminogen activator inhibitor type-1 (PAI-1) gene promoter contains 675 (4G/5G) polymorphism. The aim of this study was evaluate the effect of the PAI-1 promoter-675 (4G/5G) polymorphism on the concentrations of PAI-1 and tissue plasminogen activator/PAI-1 (t-PA/PAI-1) complex and bleeding volume after on-pump cardiac surgery. MATERIAL AND METHODS: A total of 90 patients were included in the study at Pauls Stradins Clinical University Hospital. Seven patients were excluded due to surgical bleeding. Eighty-three patients were classified according to the PAI-1 genotype: 21 patients had the 4G/4G genotype; 42, the 4G/5G genotype; and 20, the 5G/5G genotype. The following fibrinolysis parameters were recorded: the PAI-1 level preoperatively, D-dimer level at 0, 6, and 24 hours after surgery, and t-PA/PAI-1 complex level 24 hours postoperatively. A postoperative bleeding volume was registered in mL 24 hours after surgery. RESULTS: The patients with the 5G/5G genotype had significantly lower preoperative PAI-1 levels (17 [SD, 10.8] vs. 24 ng/mL [SD, 9.6], P=0.04), higher D-dimer levels at 6 hours (371 [SD, 226] vs. 232 ng/mL [SD, 185], P=0.03) and 24 hours (326 [SD, 207] vs. 209 ng/mL [SD, 160], P=0.04), and greater postoperative blood loss (568 [SD, 192] vs. 432 mL [168], P=0.02) compared with the 4G/4G carriers. There were no significant differences in the levels of the t-PA/PAI-1 complex comparing different genotype groups. CONCLUSIONS: The carriers of the 5G/5G genotype showed the lower preoperative PAI-1 levels, greater chest tube blood loss, and higher D-dimer levels indicating that the 5G/5G carriers may have enhanced fibrinolysis.

INTRODUCTION: Coagulation and fibrinolysis remain sparsely addressed with regards to acute respiratory distress syndrome (ARDS). We hypothesized that ARDS development might be associated with changes in plasma coagulation and fibrinolysis. Our aim was to investigate the relationships between ARDS diagnosis and plasma concentrations of tissue factor (TF), tissue plasminogen activator (t-PA), and plasminogen activator inhibitor-1 (PAI-1) in mechanically ventilated patients at increased risk of developing ARDS. MATERIALS AND METHODS: We performed an ethically approved prospective observational pilot study. Inclusion criteria were patients with PaO2/FiO2 < 300 mmHg admitted to the intensive care unit (ICU) for mechanical ventilation for 24 h, or more, because of one or more disease conditions associated with increased risk of developing ARDS. Exclusion criteria were age below 18 years; cardiac disease. We sampled plasma prospectively and compared patients who developed ARDS with those who did not using descriptive statistics and chi-square analysis of baseline demographical and clinical data. We also analyzed plasma concentrations of TF, t-PA, and PAI-1 at inclusion (T0) and on third (T3) and seventh day (T7) of the ICU stay with non-parametric statistics inclusive their sensitivity and specificity associated with the development of ARDS using receiver operating characteristic curve analysis. Statistical significance: p < 0.05. RESULTS: Of 24 patients at risk, 6 developed mild ARDS and 4 of each moderate or severe ARDS, respectively, 3 ± 2 (mean ± SD) days after inclusion. Median plasma concentrations of TF and PAI-1 were significantly higher at T7 in patients with ARDS, as compared to non-ARDS. Simultaneously, we found moderate correlations between plasma concentrations of TF and PAI-1, TF and PaO2/FiO2, and positive end-expiratory pressure and TF. TF plasma concentration was associated with ARDS with 71% sensitivity and 100% specificity, a cut off level of 145 pg/ml and AUC 0.78, p = 0.02. PAI-1 displayed 64% sensitivity and 100% specificity with a cut off concentration of 117.5 pg/ml and AUC 0.77, p = 0.02. t-PA did not change significantly during the observation time. CONCLUSION: This pilot study showed that increased plasma concentrations of TF and PAI-1 might support ARDS diagnoses in mechanically ventilated patients after 7 days in ICU.
