Teaching nontechnical skills in the undergraduate education of health care professionals: a nationwide cross-sectional study in Hungary.

BACKGROUND: The aim of our cross-sectional study was to evaluate the current situation and curriculum of nontechnical skills (NTS) training in the undergraduate education of health care professionals in Hungary. METHODS: All institutes with relevant NTS training in Hungarian faculties of medicine and faculties of health sciences were asked to fill out a 19-item questionnaire. Descriptive statistics were performed, and the characteristics of NTS teaching and non-NTS teaching institutes were compared. The independent predictors of teaching NTS in a particular institute were identified with multiple logistic regression. RESULTS: Seventy-seven institutes responded (52% response rate), of which 66% trained NTS. The most frequent method of NTS training is talking about them during a practice or lecture, and less than half of NTS respondents use simulation. The most frequent cause of not teaching NTS is a lack of human or technical resources. The type of faculty (p = 0.025), academic year (p = 0.001), field of medicine (p = 0.025), and importance of teamwork (p = 0.021) differed between NTS and noNTS institutes. Teaching students in academic year two represented the only independent predictor of NTS education (p = 0.012). CONCLUSIONS: Our findings show that the undergraduate curriculum of Hungarian universities includes some type of NTS education; however, this education requires further development.

Recipient Pericardial Apolipoprotein Levels Might Be an Indicator of Worse Outcomes after Orthotopic Heart Transplantation.

BACKGROUND: End-stage heart failure (ESHF) leads to hypoperfusion and edema formation throughout the body and is accompanied by neurohormonal and immunological alterations. Orthotopic heart transplantation (HTX) has been used as a beneficial option for ESHF. Due to the shortage of donor hearts, the ideal matching and timing of donors and recipients has become more important. PURPOSE: In this study, our aim was to explore the relationship between the clinical outcomes of HTX and the cytokine and apolipoprotein profiles of the recipient pericardial fluid obtained at heart transplantation after opening the pericardial sac. MATERIALS AND METHODS: The clinical data and the interleukin, adipokine, and lipoprotein levels in the pericardial fluid of twenty HTX recipients were investigated. Outcome variables included primer graft dysfunction (PGD), the need for post-transplantation mechanical cardiac support (MCS), International Society for Heart and Lung Transplantation grade ≥2R rejection, and mortality. Recipient risk scores were also investigated. RESULTS: Leptin levels were significantly lower in patients with PGD than in those without PGD (median: 6.36 (IQR: 5.55-6.62) versus 7.54 (IQR = 6.71-10.44); p = 0.029). Higher ApoCII levels (median: 14.91 (IQR: 11.55-21.30) versus 10.31 (IQR = 10.02-13.07); p = 0.042) and ApoCIII levels (median: 60.32 (IQR: 43.00-81.66) versus 22.84 (IQR = 15.84-33.39); p = 0.005) were found in patients (n = 5) who died in the first 5 years after HTX. In patients who exhibited rejection (n = 4) in the first month after transplantation, the levels of adiponectin (median: 74.48 (IQR: 35.51-131.70) versus 29.96 (IQR: 19.86-42.28); p = 0.039), ApoCII (median: 20.11 (IQR: 13.06-23.54) versus 10.32 (IQR: 10.02-12.84); p = 0.007), and ApoCIII (median: 70.97 (IQR: 34.72-82.22) versus 26.33 (IQR: 17.18-40.17); p = 0.029) were higher than in the nonrejection group. Moreover, the pericardial thyroxine (T4) levels (median: 3.96 (IQR: 3.49-4.46) versus 4.69 (IQR: 4.23-5.77); p = 0.022) were lower in patients with rejection than in patients who did not develop rejection. CONCLUSION: Our results indicate that apolipoproteins can facilitate the monitoring of rejection and could be a useful tool in the forecasting of early and late complications.

Donor Pericardial Interleukin and Apolipoprotein Levels May Predict the Outcome after Human Orthotopic Heart Transplantation.

The proinflammatory cascade that is activated at the time of brain death plays a crucial role in organ procurement. Our aim of this study was to explore the relationship between the clinical outcome of orthotopic heart transplantation, as well as cytokine and apolipoprotein profiles of the pericardial fluid obtained at donation. Interleukin, adipokine and lipoprotein levels in the pericardial fluid, as well as clinical data of twenty donors after brain death, were investigated. Outcome variables included primary graft dysfunction, the need for posttransplantation mechanical cardiac support and International Society for Heart and Lung Transplantation grade ≥ 2R rejection. Hormone management and donor risk scores were also investigated. Lower levels of IL-6 were observed in primary graft dysfunction (median: 36.72 [IQR: 19.47-62.90] versus 183.67 [41.21-452.56]; p = 0.029) and in the need for mechanical cardiac support (44.12 [20.12-85.70] versus 247.13 [38.51-510.38]; p = 0.043). Rejection was associated with lower ApoAII (p = 0.021), ApoB100 (p = 0.032) and ApoM levels (p = 0.025). Lower adipsin levels were detected in those patients receiving desmopressin (p = 0.037); moreover, lower leptin levels were found in those patients receiving glucocorticoid therapy (p = 0.045), and higher T3 levels were found in those patients treated with L-thyroxine (p = 0.047) compared to those patients not receiving these hormone replacement therapies. IL-5 levels were significantly associated with UNOS-D score (p = 0.004), Heart Donor Score (HDS) and Adapted HDS (p < 0.001). The monitoring of immunological and metabolic changes in donors after brain death may help in the prediction of potential complications after heart transplantation, thus potentially optimizing donor heart allocation.

Poor Preoperative Nutritional Status, but Not Hormone Levels, Are Associated With Mortality After Cardiac Surgery.

OBJECTIVES: The authors' aim was to examine the preoperative hormone and nutritional status in patients undergoing elective cardiac surgery. DESIGN AND SETTINGS: The authors' research was a single-center, prospective, observational study (ClinicalTrials.gov: NCT03736499). PARTICIPANTS & INTERVENTIONS: The authors examined 252 patients who underwent elective cardiac surgery. Preoperative thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), prolactin, and testosterone levels were collected and analyzed after the surgery. The Geriatric Nutritional Risk Index (GNRI), Controlling Nutritional Status (CONUT), and Prognostic Nutritional Index (PNI) were all calculated as a sum and groups. Frailty was calculated based on the modified Frailty Index-11. The primary outcome was overall mortality. MEASUREMENTS AND MAIN RESULTS: The mean age of the patients was 64.23 years (standard deviation: 11.07 years). Thirty-three patients (13.01%) died during the median follow-up time of 20.48 months (interquartile range: 18.90-22.98 months). Thyroid hormones were examined as continuous variables and also in 3 groups based on low, normal, and high hormone levels. Continuous TSH (p = 0.230), continuous fT3 (p = 0.492), and continuous fT4 (p = 0.657) were not significantly associated with total mortality. After adjustment for the European System for Cardiac Operative Risk Evaluation II and postoperative complications, the following nutritional scores were associated with total mortality: GNRI < 91 (adjusted hazard ratio [AHR]: 4.384; 95% confidence interval [CI]: 1.866-10.303, p = 0.001), the higher CONUT group (AHR: 1.736; 95% CI: 1.736-2.866, p = 0.031), and a PNI < 48 points (AHR: 3.465; 95% CI: 1.735-6.918, p < 0.001). The modified Frailty Index-11 was not associated with mortality. CONCLUSIONS: Before cardiac surgery, nutritional status should be assessed because the findings may help to decrease mortality. The hormone levels were not associated with mortality.

European Association of Cardiothoracic Anesthesiology and Intensive Care Pediatric Cardiac Anesthesia Fellowship Curriculum: First Edition.

Pediatric cardiac anesthesia is a subspecialty of cardiac and pediatric anesthesiology dedicated to the perioperative care of patients with congenital heart disease. Members of the Congenital and Education Subcommittees of the European Association of Cardiothoracic Anaesthesiology and Intensive Care (EACTAIC) agreed on the necessity to develop an EACTAIC pediatric cardiac anesthesia fellowship curriculum. This manuscript represents a consensus on the composition and the design of the EACTAIC Pediatric Cardiac Anesthesia Fellowship program. This curriculum provides a basis for the training of future pediatric cardiac anesthesiologists by clearly defining the theoretical and practical requirements for fellows and host centers.

ADHD symptomatology of children with congenital heart disease 10 years after cardiac surgery: the role of age at operation.

BACKGROUND: The aim of the present study was to investigate the differences in ADHD symptomatology between healthy controls and children who underwent cardiac surgery at different ages. METHODS: Altogether, 133 children (54 patients with congenital heart disease undergoing first cardiac surgery under 3 years of age, 26 operated at the age of 3 or later, and 53 healthy controls) were examined. Patients completed the Youth Self Report (YSR), while their parents completed the Child Behaviour Checklist (CBCL) and the ADHD Rating Scale-IV. RESULTS: Children receiving surgery for the first time under the age of 3 years were more likely diagnosed with cyanotic type malformation and have undergone to a greater number of operations. However, ADHD symptoms of those treated surgically at or above 3 years of age were more severe than that of the control group or those who were treated surgically at a younger age. The control group and those treated surgically below the age of three did not differ across any of the ADHD symptom severity indicators. CONCLUSIONS: The age at the time of cardiac surgery might be associated with later ADHD symptom severity - with lower age at operation associated with better outcomes. Further, adequately powered studies are needed to confirm these exploratory findings and investigate the moderators of this relationship.

The effect of cognitive dysfunction on mid- and long-term mortality after vascular surgery.

BACKGROUND: In recent decades, previous studies have noted the importance of frailty, which is a frequently used term in perioperative risk evaluations. Psychological and socioeconomical domains were investigated as part of frailty syndrome. The aim of this study was to assess the importance of these factors in mortality after vascular surgery. METHODS: In our prospective, observational study (ClinicalTrials.gov Identifier: NCT02224222), we examined 164 patients who underwent elective vascular surgery between 2014 and 2017. At the outpatient anaesthesiology clinic, patients completed a questionnaire about cognitive functions, depression and anxiety, social support and self-reported quality of life were assessed using a comprehensive frailty index, in addition to medical variables. Propensity score matching was performed to analyse the difference between patients and controls in a nationwide population cohort. The primary outcome was 4 year mortality. The Kaplan-Meier method and Cox regression analysis were used for statistical analyses. RESULTS: The patients' mean age was 67.05 years (SD: 9.49 years). Mini-Mental State Examination scores of less than 27 points were recorded for 41 patients. Overall mortality rates were 22.4 and 47.6% in the control and cognitive impairment groups, respectively (p = 0.013). In the univariate Cox regression analysis, cognitive impairment measured using age- and education-adjusted MMSE scores increased the risk of mortality (AHR: 2.842, 95% CI: 1.389-5.815, p = 0.004). CONCLUSION: Even mild cognitive dysfunction measured preoperatively using the MMSE represents a potentially important risk factor for mortality after vascular surgery.

Vasopressor Therapy in Cardiac Surgery-An Experts' Consensus Statement.

Hemodynamic conditions with reduced systemic vascular resistance commonly are observed in patients undergoing cardiac surgery and may range from moderate reductions in vascular tone, as a side effect of general anesthetics, to a profound vasodilatory syndrome, often referred to as vasoplegic shock. Therapy with vasopressors is an important pillar in the treatment of these conditions. There is limited guidance on the appropriate choice of vasopressors to restore and optimize systemic vascular tone in patients undergoing cardiac surgery. A panel of experts in the field convened to develop statements and evidence-based recommendations on clinically relevant questions on the use of vasopressors in cardiac surgical patients, using a critical appraisal of the literature following the GRADE system and a modified Delphi process. The authors unanimously and strongly recommend the use of norepinephrine and/or vasopressin for restoration and maintenance of systemic perfusion pressure in cardiac surgical patients; despite that, the authors cannot recommend either of these drugs with respect to the risk of ischemic complications. The authors unanimously and strongly recommend against using dopamine for treating post-cardiac surgery vasoplegic shock and against using methylene blue for purposes other than a rescue therapy. The authors unanimously and weakly recommend that clinicians consider early addition of a second vasopressor (norepinephrine or vasopressin) if adequate vascular tone cannot be restored by a monotherapy with either norepinephrine or vasopressin and to consider using vasopressin as a first-line vasopressor or to add vasopressin to norepinephrine in cardiac surgical patients with pulmonary hypertension or right-sided heart dysfunction.

Perioperative Low Tetraiodothyronine Levels and Adverse Outcomes After Heart Transplantation: A Retrospective, Observational Study.

OBJECTIVES: Thyroid dysfunction has been shown to be associated with increased all-cause mortality and severity of chronic heart failure in critical illness and severe cardiac diseases. The present study was conducted to ascertain the relationship between perioperative free triiodothyronine and free tetraiodothyronine (fT4) levels and postoperative adverse outcomes after heart transplantation (HTX). DESIGN: Retrospective, observational study. SETTING: Single-center study in a quaternary care university clinical center. PARTICIPANTS: The study comprised adult patients who underwent HTX between 2015 and 2019 and had at least 1 perioperative thyroid hormone laboratory test on the day of surgery or in the 24 hours before/after the procedure (free triiodothyronine, fT4, and thyroid-stimulating hormone). INTERVENTIONS: No interventions were applied. MEASUREMENTS AND MAIN RESULTS: The primary outcome was primary graft dysfunction (PGD), defined by the consensus conference of the International Society for Heart and Lung Transplantation. A total of 151 patients were included in the final analyses. Twenty-nine (19.2%) patients had PGD. Fourteen (9.3%) patients had low fT4 levels. An independent association was found between fT4 and PGD (odds ratio 6.49; 95% confidence interval 2.26-18.61; p = 0.001), with adjusted multivariate Cox regression models. CONCLUSION: The perioperative fT4 level could be a prognostic marker of adverse outcomes in HTX. The authors suggest appropriate perioperative monitoring of fT4 levels. Additional research is warranted to examine the optimal timing, dosage, and method of replacement.

European Association of Cardiothoracic Anesthesiology (EACTA) Cardiothoracic and Vascular Anesthesia Fellowship Curriculum: First Edition.

This special article summarizes the design and certification process of the European Association of Cardiothoracic Anesthesiology (EACTA) Cardiothoracic and Vascular Anesthesia (CTVA) Fellowship Program. The CTVA fellowship training includes a two-year curriculum at an EACTA-accredited educational facility. Before fellows are accepted into the program, they must meet a number of requirements, including evidence of a valid license to practice medicine, a specialist degree examination in anesthesiology, and appropriate language skills as required in the host centers. The CVTA Fellowship Program has 2 sequential and complementary levels of training-both with a modular structure that allows for individual planning and also takes into account the differing national healthcare needs and requirements of the 36 countries represented in EACTA. The basic training period focuses on the anesthetic management of patients undergoing cardiac, thoracic, and vascular surgery and related procedures. The advanced training period is intended to deepen and to extend the clinical and nontechnical skills that fellows have acquired during the basic training. The goal of the EACTA fellowship is to produce highly trained and competent perioperative physicians who are able to care for patients undergoing cardiac, thoracic, and vascular anesthesia.

Multicenter International Survey on the Clinical Practice of Ultra-Fast-Track Anesthesia with On-Table Extubation in Pediatric Congenital Cardiac Surgery.

OBJECTIVE: To describe global practices for on-table extubation (OTE) in pediatric cardiac anesthesia in European and non-European countries. DESIGN: Multiple-choice, web-based survey with 34 questions addressing organizational data, existence of OTE programs, inclusion and exclusion criteria for OTE, and intraoperative and immediate postoperative management. SETTING: Online survey endorsed by the European Association of Cardiothoracic Anesthesiologists. PARTICIPANTS: Anesthesiologists departments in European and non-European pediatric cardiac surgical centers. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The survey was sent to 144 pediatric cardiac surgical centers in 29 countries as a web-based questionnaire. Addressees were pediatric cardiac anesthesiologists who were members of European Association of Cardiothoracic Anesthesiologists or were known to the authors. The response rate was 63%. Fifty percent of the respondents were practicing in university hospitals. The survey demonstrated that 76% of the respondents practiced OTE, with 50% of the pediatric cardiac anesthesiologists regularly performing OTE in different proportions, ranging from 1 to 51% of on-pump pediatric cardiac surgeries. Seventy-seven percent of respondents made their decision to perform OTE on an individual case-by-case basis. Seventy-eight percent of the congenital cardiac lesions deemed eligible for OTE fell into Risk Adjustment for Congenital Heart Surgery-1 categories 1 and 2. In patients for whom OTE was planned, anesthesia primarily was maintained using a combined inhalational and intravenous technique. The main reasons not to perform OTE were that it was deemed to provide no major advantage (45%), to be dangerous (9%), or to decrease operating room efficiency by increasing operating room turnover time (36%). CONCLUSION: The survey demonstrated that the majority of the approached pediatric cardiac anesthesiologists practice OTE regularly in pediatric cardiac surgery. Frequency of OTE and inclusion criteria vary widely. The observations made in this survey should prompt appropriately powered, randomized controlled clinical trials to examine the effect of OTE on various effectiveness and safety outcomes.

The Impact of l-Thyroxine Treatment of Donors and Recipients on Postoperative Outcomes After Heart Transplantation.

OBJECTIVE: The effect of thyroid dysfunction on adverse outcomes has been studied in many different patient populations. The objective of this study was to investigate the effect of thyroid hormone supplementation of donors and recipients on postoperative outcomes after orthotopic heart transplantation. DESIGN: Retrospective. SETTING: Single center, university hospital. PARTICIPANTS: Two-hundred and sixty-six consecutive patients undergoing heart transplantation. INTERVENTIONS: No interventions. MEASUREMENTS AND MAIN RESULTS: Demographic, hemodynamic, and clinical characteristics; donor and recipient United Network for Organ Sharing scores; and information on thyroid hormone support of donors and recipients were recorded. During the median follow-up of 4.59 years (interquartile range 4.26-4.92 y), 70 patients (26.3%) died. After adjustments were made for the United Network for Organ Sharing score, recipients who were treated preoperatively with l-thyroxine had a lower risk for all-cause mortality (adjusted hazard ratio [HR] 0.24, 95% confidence interval [CI] 0.06-0.98; p = 0.047) compared with recipients who were not treated with l-thyroxine. In addition, l-thyroxine treatment of donors was associated with a better recipient survival (HR 0.31, 95% CI 0.11-0.87; p = 0.025). CONCLUSIONS: Pretransplantation thyroid hormone supplementation of donors and recipients was associated with improved long-term survival after heart transplantation.

Analysis of blood supply in the hard palate and maxillary tuberosity-clinical implications for flap design and soft tissue graft harvesting (a human cadaver study).

OBJECTIVES: The aim of the present study is to provide a detailed macroscopic mapping of the palatal and tuberal blood supply applying anatomical methods and studying specific anastomoses to bridge the gap between basic structural and empirical clinical knowledge. MATERIALS AND METHODS: Ten cadavers (three dentate, seven edentulous) have been prepared for this study in the Department of Anatomy, Semmelweis University, Budapest, Hungary, and in the Department of Anatomy of the Medical University of Graz. All cadavers were fixed with Thiel's solution. For the macroscopic analysis of the blood vessels supplying the palatal mucosa, corrosion casting in four cadavers and latex milk injection in other six cadavers were performed. RESULTS: We recorded major- and secondary branches of the greater palatine artery (GPA) and its relation to the palatine spine, different anastomoses with the nasopalatine artery (NPA), and lesser palatal artery (LPA) as well as with contralateral branches of the GPA. Penetrating intraosseous branches at the premolar-canine area were also detected. In edentulous patients, the GPA developed a curvy pathway in the premolar area. The blood supply around the maxillary tuberosity was also presented. CONCLUSION: The combination of different staining methods has shed light to findings with relevance to palatal blood supply, offering a powerful tool for the design and execution of surgical interventions involving the hard palate. CLINICAL RELEVANCE: The present study provides clinicians with a good basis to understand the anatomical background of palatal and tuberal blood supply. This might enable clinicians to design optimized incision- and flap designs. As a result, the risk of intraoperative bleeding and postoperative wound healing complications related to impaired blood supply can be minimized.

The legacy of Václav Trnka: modern medical education in Slovakia and Hungary in the eighteenth century.

A fresh start of higher medical education in Slovakia and Hungary is closely related to Trnava (Nagyszombat). The University of Trnava had originally been established in 1635 but the Faculty of Medicine was added only later, in 1769, when the name of the university was also changed to Royal Hungarian University of Sciences. A fresh graduate, Václav Trnka from Krovice (1739-1791), was appointed as head of the Department of Anatomy. He was not only an anatomist, but a real polymath of the second half of the eighteenth century practicing medicine as well as becoming the Dean, then the Rector of the University. He has lived and acted within several countries of Central Europe, or rather, the Austrio-Hungarian monarchy during the reign of Empress Maria Theresia, then her son Joseph II. Born in Bohemia (now Czech Republic), studied and graduated in Austria, then finally was appointed as the first Professor of Anatomy of a newly established medical faculty in Upper Hungary (now Slovakia). In 1777, the university was moved first to Buda, then to Pest (now parts of the capital of Hungary), and the Faculty of Medicine was not separated from the rest of the faculties before the end of the Second World War. Following several institutional and name changes, this Medical Faculty is considered as the foundation of the present Semmelweis University. Trnka was a proliferous author, publishing more than 20 monographs covering various branches of clinical medicine, however, no anatomical work may be connected to his activity. And as a typical intellectual of the era, he was a keen and talented musician composing several canons.

Higher Transaminase Levels in the Postoperative Period After Orthotopic Heart Transplantation Are Associated With Worse Survival.

OBJECTIVE: Preoperative liver function in heart failure patients is associated with extensive functional, structural, and hemodynamic abnormalities. The authors hypothesized that perioperative liver dysfunction is associated with worse 2-year survival after orthotopic heart transplantation. DESIGN: Retrospective study. SETTING: Single-center, university hospital. PARTICIPANTS: The study comprised 209 consecutive patients undergoing heart transplantation. INTERVENTIONS: No interventions. MEASUREMENTS AND MAIN RESULTS: Hepatobiliary markers, hemodynamic parameters, echocardiographic parameters, the need for mechanical cardiac support, demographic parameters, and United Network for Organ Sharing and Model for End-Stage Liver Disease (MELD) scores were investigated. Fifty-five patients (26.3%) died, and the mean survival time was 3.61 years after transplantation. In multivariate Cox regression analysis, in addition to the preoperative modified MELD score, the 4th quartiles of the maximum aspartate transaminase (AST) and alanine transaminase levels on the 4th through 7th postoperative days were independently associated with mortality (odds ratio [OR] 2.46, 95% confidence interval [CI] 1.09-5.55; p = 0.031 and OR 2.41, 95% CI 1.13-5.18; p = 0.024, respectively). By expressing the transaminase values as the multiplier of the sex-specific top normal value, the maximum AST and alanine transaminase levels (OR 1.02, 95% CI 1.01-1.02; p < 0.001 and OR 1.02, 95% CI 1.01-1.03; p = 0.001, respectively) were linked to worse survival. Among the postdischarge parameters, the modified MELD score (OR 1.17, 95% CI 1.09-1.27; p < 0.001) and the AST level were associated with postdischarge mortality (OR 1.002, 95% CI 1.001-1.003; p < 0.001 as a continuous variable; OR 1.07, 95% CI 1.05-1.10; p < 0.001, expressed as the multiplier of the sex-specific normal value, respectively). CONCLUSIONS: The severity of postoperative liver dysfunction negatively influences survival after heart transplantation, and liver function should be closely assessed in these patients.

Nonsurgical Strategies to Reduce Mortality in Patients Undergoing Cardiac Surgery: An Updated Consensus Process.

OBJECTIVE: A careful choice of perioperative care strategies is pivotal to improve survival in cardiac surgery. However, there is no general agreement or particular attention to which nonsurgical interventions can reduce mortality in this setting. The authors sought to address this issue with a consensus-based approach. DESIGN: A systematic review of the literature followed by a consensus-based voting process. SETTING: A web-based international consensus conference. PARTICIPANTS: More than 400 physicians from 52 countries participated in this web-based consensus conference. INTERVENTIONS: The authors identified all studies published in peer-reviewed journals that reported on interventions with a statistically significant effect on mortality in the setting of cardiac surgery through a systematic Medline/PubMed search and contacts with experts. These studies were discussed during a consensus meeting and those considered eligible for inclusion in this study were voted on by clinicians worldwide. MEASUREMENTS AND MAIN RESULTS: Eleven interventions finally were selected: 10 were shown to reduce mortality (aspirin, glycemic control, high-volume surgeons, prophylactic intra-aortic balloon pump, levosimendan, leuko-depleted red blood cells transfusion, noninvasive ventilation, tranexamic acid, vacuum-assisted closure, and volatile agents), whereas 1 (aprotinin) increased mortality. A significant difference in the percentages of agreement among different countries and a variable gap between agreement and clinical practice were found for most of the interventions. CONCLUSIONS: This updated consensus process identified 11 nonsurgical interventions with possible survival implications for patients undergoing cardiac surgery. This list of interventions may help cardiac anesthesiologists and intensivists worldwide in their daily clinical practice and can contribute to direct future research in the field.

Randomized Evidence for Reduction of Perioperative Mortality: An Updated Consensus Process.

OBJECTIVE: Of the 230 million patients undergoing major surgical procedures every year, more than 1 million will die within 30 days. Thus, any nonsurgical interventions that help reduce perioperative mortality might save thousands of lives. The authors have updated a previous consensus process to identify all the nonsurgical interventions, supported by randomized evidence, that may help reduce perioperative mortality. DESIGN AND SETTING: A web-based international consensus conference. PARTICIPANTS: The study comprised 500 clinicians from 61 countries. INTERVENTIONS: A systematic literature search was performed to identify published literature about nonsurgical interventions, supported by randomized evidence, showing a statistically significant impact on mortality. A consensus conference of experts discussed eligible papers. The interventions identified by the conference then were submitted to colleagues worldwide through a web-based survey. MEASUREMENTS AND MAIN RESULTS: The authors identified 11 interventions contributing to increased survival (perioperative hemodynamic optimization, neuraxial anesthesia, noninvasive ventilation, tranexamic acid, selective decontamination of the gastrointestinal tract, insulin for tight glycemic control, preoperative intra-aortic balloon pump, leuko-depleted red blood cells transfusion, levosimendan, volatile agents, and remote ischemic preconditioning) and 2 interventions showing increased mortality (beta-blocker therapy and aprotinin). Interventions then were voted on by participating clinicians. Percentages of agreement among clinicians in different countries differed significantly for 6 interventions, and a variable gap between evidence and clinical practice was noted. CONCLUSIONS: The authors identified 13 nonsurgical interventions that may decrease or increase perioperative mortality, with variable agreement by clinicians. Such interventions may be optimal candidates for investigation in high-quality trials and discussion in international guidelines to reduce perioperative mortality.

Inhibitory Effects of Diclofenac on Steroid Glucuronidation In Vivo Do Not Affect Hair-Based Doping Tests for Stanozolol.

In vitro studies show that diclofenac inhibits enzymatic steroid glucuronidation. This study was designed to investigate the influence of diclofenac on the excretion of stanozolol and 3'-hydroxystanozolol via analyses in hair, blood and urine in vivo in a rat study. Brown Norway rats were administered with stanozolol (weeks 1-3) and diclofenac (weeks 1-6). Weekly assessment of steroid levels in hair was complemented with spot urine and serum tests. Levels of both stanozolol and 3'-hydroxystanozolol steadily increased in hair during stanozolol treatment and decreased post-treatment, but remained readily detectable for 6 weeks. In contrast, compared to control rats, diclofenac significantly reduced urinary excretion of 3'-hydroxystanozolol which was undetectable in most samples. This is the first report of diclofenac altering steroid metabolism in vivo, detrimentally affecting detection in urine, but not in hair, which holds considerable advantages over urinalysis for anti-doping tests.

Fluid Overload Is Associated With Higher Mortality and Morbidity in Pediatric Patients Undergoing Cardiac Surgery.

OBJECTIVES: Fluid overload after pediatric cardiac surgery is common and has been shown to increase both mortality and morbidity. This study explores the risk factors of early postoperative fluid overload and its relationship with adverse outcomes. DESIGN: Secondary analysis of the prospectively collected data of children undergoing open-heart surgery between 2004 and 2008. SETTING: Tertiary national cardiac center. PATIENTS: One thousand five hundred twenty consecutive pediatric patients (<18 years old) were included in the analyses. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: In the first 72 hours of the postoperative period, the daily fluid balance was calculated as milliliter per kilogram and the daily fluid overload was calculated as fluid balance (L)/weight (kg) × 100. The primary endpoint was in-hospital mortality; the secondary outcomes were low cardiac output syndrome and prolonged mechanical ventilation. One thousand three hundred and sixty-seven patients (89.9%) had a cumulative fluid overload below 5%; 120 patients (7.8%), between 5% and 10%; and 33 patients (2.1%), above 10%. After multivariable analysis, higher fluid overload on the day of the surgery was independently associated with mortality (adjusted odds ratio, 1.14; 95% CI, 1.008-1.303; p = 0.041) and low cardiac output syndrome (adjusted odds ratio, 1.21; 95% CI, 1.12-1.30; p = 0.001). Higher maximum serum creatinine levels (adjusted odds ratio, 1.01; 95% CI, 1.003-1.021; p = 0.009), maximum vasoactive-inotropic scores (adjusted odds ratio, 1.01; 95% CI, 1.005-1.029; p = 0.042), and higher blood loss on the day of the surgery (adjusted odds ratio, 1.01; 95% CI, 1.004-1.025; p = 0.015) were associated with a higher risk of fluid overload that was greater than 5%. CONCLUSIONS: Fluid overload in the early postoperative period was associated with higher mortality and morbidity. Risk factors for fluid overload include underlying kidney dysfunction, hemodynamic instability, and higher blood loss on the day of the surgery.
