RESUMEN
Airway management is required during general anaesthesia and is essential for life-threatening conditions such as cardiopulmonary resuscitation. Evidence from recent trials indicates a high incidence of critical events during airway management, especially in neonates or infants. It is important to define the optimal techniques and strategies for airway management in these groups. In this joint European Society of Anaesthesiology and Intensive Care (ESAIC) and British Journal of Anaesthesia (BJA) guideline on airway management in neonates and infants, we present aggregated and evidence-based recommendations to assist clinicians in providing safe and effective medical care. We identified seven main areas of interest for airway management: i) preoperative assessment and preparation; ii) medications; iii) techniques and algorithms; iv) identification and treatment of difficult airways; v) confirmation of tracheal intubation; vi) tracheal extubation, and vii) human factors. Based on these areas, Population, Intervention, Comparison, Outcomes (PICO) questions were derived that guided a structured literature search. GRADE (Grading of Recommendations, Assessment, Development and Evaluation) methodology was used to formulate the recommendations based on those studies included with consideration of their methodological quality (strong '1' or weak '2' recommendation with high 'A', medium 'B' or low 'C' quality of evidence). In summary, we recommend: 1. Use medical history and physical examination to predict difficult airway management (1C). 2. Ensure adequate level of sedation or general anaesthesia during airway management (1B). 3. Administer neuromuscular blocker before tracheal intubation when spontaneous breathing is not necessary (1C). 4. Use a videolaryngoscope with an age-adapted standard blade as first choice for tracheal intubation (1B). 5. Apply apnoeic oxygenation during tracheal intubation in neonates (1B). 6. Consider a supraglottic airway for rescue oxygenation and ventilation when tracheal intubation fails (1B). 7. Limit the number of tracheal intubation attempts (1C). 8. Use a stylet to reinforce and preshape tracheal tubes when hyperangulated videolaryngoscope blades are used and when the larynx is anatomically anterior (1C). 9. Verify intubation is successful with clinical assessment and end-tidal CO2 waveform (1C). 10. Apply high-flow nasal oxygenation, continuous positive airway pressure or nasal intermittent positive pressure ventilation for postextubation respiratory support, when appropriate (1B).

BACKGROUND: Oesophageal atresia with or without a tracheo-oesophageal fistula is a congenital abnormality that usually requires surgical repair within the first days of life. OBJECTIVE: Description of the perioperative anaesthetic management and outcomes of neonates undergoing surgery for oesophageal atresia with or without a tracheo-oesophageal fistula, included in the 'neonate and children audit of anaesthesia practice in Europe' (NECTARINE) database. DESIGN: Sub-analyses of prospective observational NECTARINE study. SETTING: European multicentre study. PATIENTS: Neonates who underwent surgery for oesophageal atresia with or without a tracheo-oesophageal fistula in the NECTARINE cohort were selected. MAIN OUTCOME MEASURES: Incidence rates with 95% confidence intervals were calculated for peri-operative clinical events which required a predetermined intervention, postoperative complications, and mortality. RESULTS: One hundred and three neonates undergoing a first surgical intervention for oesophageal atresia with or without a tracheo-oesophageal fistula repair were identified. Their median gestational age was 38âweeks with a median birth weight of 2840 [interquartile range 2150 to 3150] grams. Invasive monitoring was used in 66% of the procedures. The incidence of perioperative clinical events was 69% (95% confidence interval 59 to 77%), of 30-day postoperative complications 47% (95% confidence interval 38 to 57%) and the 30- and 90âdays mortality rates were 2.1% and 2.6%, respectively. CONCLUSION: Oesophageal atresia with or without a tracheo-oesophageal fistula repair in neonates is associated with a high number of perioperative interventions in response to clinical events, a high incidence of postoperative complications, and a substantial mortality rate.

BACKGROUND AND PURPOSE: Patients with neuromuscular conditions are at increased risk of suffering perioperative complications related to anaesthesia. There is currently little specific anaesthetic guidance concerning these patients. Here, we present the European Neuromuscular Centre (ENMC) consensus statement on anaesthesia in patients with neuromuscular disorders as formulated during the 259th ENMC Workshop on Anaesthesia in Neuromuscular Disorders. METHODS: International experts in the field of (paediatric) anaesthesia, neurology, and genetics were invited to participate in the ENMC workshop. A literature search was conducted in PubMed and Embase, the main findings of which were disseminated to the participants and presented during the workshop. Depending on specific expertise, participants presented the existing evidence and their expert opinion concerning anaesthetic management in six specific groups of myopathies and neuromuscular junction disorders. The consensus statement was prepared according to the AGREE II (Appraisal of Guidelines for Research & Evaluation) reporting checklist. The level of evidence has been adapted according to the SIGN (Scottish Intercollegiate Guidelines Network) grading system. The final consensus statement was subjected to a modified Delphi process. RESULTS: A set of general recommendations valid for the anaesthetic management of patients with neuromuscular disorders in general have been formulated. Specific recommendations were formulated for (i) neuromuscular junction disorders, (ii) muscle channelopathies (nondystrophic myotonia and periodic paralysis), (iii) myotonic dystrophy (types 1 and 2), (iv) muscular dystrophies, (v) congenital myopathies and congenital dystrophies, and (vi) mitochondrial and metabolic myopathies. CONCLUSIONS: This ENMC consensus statement summarizes the most important considerations for planning and performing anaesthesia in patients with neuromuscular disorders.

At the outbreak of World War II (WWII), anesthesiology was struggling to establish itself as a medical specialty. The battlefield abruptly exposed this young specialty to the formidable challenge of mass casualties, with an urgent need to provide proper fluid resuscitation, airway management, mechanical ventilation, and analgesia to thousands. But while Europe was suffering under the Nazi boot, anesthesia was preparing to rise to the challenge posed by the impending war. While war brings death and destruction, it also opens the way to medical advances. The aim of this study is to measure the evolution of anesthesia owing to WWII. We conducted a retrospective observational bibliometric study involving a quantitative and statistical analysis of publications. The following 7 journals were selected to cover European and North American anesthesia-related publications: Anesthesia & Analgesia, the British Journal of Anaesthesia, Anesthesiology, Schmerz-Narkose-Anaesthesie, Surgery, La Presse Médicale, and The Military Surgeon (later Military Medicine). Attention was focused on journal volumes published between 1920 and 1965. After reviewing the literature, we selected 12 keywords representing important advances in anesthesiology since 1920: "anesthesia," "balanced anesthesia," "barbiturates," "d-tubocurarine," "endotracheal intubation," "ether," "lidocaine," "morphine," "spinal anesthesia," "thiopental," "transfusion," and "trichloroethylene." Titles of original articles from all selected journals editions between 1920 and 1965 were screened for the occurrence of 1 of the 12 keywords. A total of 26,132 original article titles were screened for the occurrence of the keywords. A total of 1815 keywords were found. Whereas Anesthesia & Analgesia had the highest keyword occurrence (493 citations), Schmerz-Narkose-Anaesthesie had the lowest (38 citations). The number of publications of the 12 keywords was significantly higher in the postwar than in the prewar period (65% and 35%, respectively; P < .001). Not surprisingly, the anesthesiology journals have a higher occurrence of keywords than those journals covering other specialties. The overall occurrence of keywords also showed peaks during other major conflicts, namely the Spanish Civil War (1936-1939), the Korean War (1950-1953), and the Vietnam War (1955-1975). For the first time, this study demonstrates statistically the impact of WWII on the progress of anesthesiology. It also offers an objective record of the chronology of the major advances in anesthesiology before and after the conflict. While the war arguably helped to enhance anesthesiology as a specialty, in return anesthesiology helped to heal the wounds of war.

Congenital lung lesions are numerous but rare in individual clinical practice. They do require close multidisciplinary collaboration between health care professionals. This educational review will focus on the pathophysiology, clinical manifestations, surgical approaches, and anesthetic management of congenital anomalies of the large intrathoracic airways: congenital tracheal stenosis, tracheal agenesis, tracheal diverticulum, bronchial anomalies (tracheal, esophageal, or bridging bronchus), congenital lung malformations, lung sequestrations and Scimitar syndrome, lobar emphysema, Williams-Campbell syndrome, and pleuropulmonary blastoma. In addition, this review will illustrate common pitfalls and challenges related to the anesthesia management with emphasis on ventilation and correct endotracheal tube positioning.

Congenital interstitial lung diseases can affect both adults and children. Pediatric congenital interstitial lung diseases generally carry high risk for morbidly and mortality and include congenital alveolar capillary dysplasia with misalignment of pulmonary veins, congenital alveolar dysplasia, acinar dysplasia, congenital pulmonary lymphangiectasis, diffuse pulmonary lymphangiomatosis, neuroendocrine cell hyperplasia of infancy, pulmonary hemosiderosis, pulmonary alveolar proteinosis, and pulmonary interstitial glycogenosis. Given their usual non-specific clinical presentation, they are frequently misdiagnosed and recognized late, particularly in children who have been apparently healthy for several years (eg, diffuse pulmonary lymphangiomatosis). Some diseases have a very poor prognosis, whereas others have a benign course with appropriate treatment. The current manuscript reviews congenital interstitial lung diseases that typically affect neonates and young children and may be encountered by the pediatric anesthesiologist.

Current paediatric anaesthetic fasting guidelines have recommended conservative fasting regimes for many years and have not altered much in the last decades. Recent publications have employed more liberal fasting regimes with no evidence of increased aspiration or regurgitation rates. In this first solely paediatric European Society of Anaesthesiology and Intensive Care (ESAIC) pre-operative fasting guideline, we aim to present aggregated and evidence-based summary recommendations to assist clinicians, healthcare providers, patients and parents. We identified six main topics for the literature search: studies comparing liberal with conservative regimens; impact of food composition; impact of comorbidity; the use of gastric ultrasound as a clinical tool; validation of gastric ultrasound for gastric content and gastric emptying studies; and early postoperative feeding. The literature search was performed by a professional librarian in collaboration with the ESAIC task force. Recommendations for reducing clear fluid fasting to 1âh, reducing breast milk fasting to 3âh, and allowing early postoperative feeding were the main results, with GRADE 1C or 1B evidence. The available evidence suggests that gastric ultrasound may be useful for clinical decision-making, and that allowing a 'light breakfast' may be well tolerated if the intake is well controlled. More research is needed in these areas as well as evaluation of how specific patient or treatment-related factors influence gastric emptying.

BACKGROUND: Neonates and infants requiring anaesthesia are at risk of physiological instability and complications, but triggers for peri-anaesthetic interventions and associations with subsequent outcome are unknown. METHODS: This prospective, observational study recruited patients up to 60 weeks' postmenstrual age undergoing anaesthesia for surgical or diagnostic procedures from 165 centres in 31 European countries between March 2016 and January 2017. The primary aim was to identify thresholds of pre-determined physiological variables that triggered a medical intervention. The secondary aims were to evaluate morbidities, mortality at 30 and 90 days, or both, and associations with critical events. RESULTS: Infants (n=5609) born at mean (standard deviation [sd]) 36.2 (4.4) weeks postmenstrual age (35.7% preterm) underwent 6542 procedures within 63 (48) days of birth. Critical event(s) requiring intervention occurred in 35.2% of cases, mainly hypotension (>30% decrease in blood pressure) or reduced oxygenation (SpO2 <85%). Postmenstrual age influenced the incidence and thresholds for intervention. Risk of critical events was increased by prior neonatal medical conditions, congenital anomalies, or both (relative risk [RR]=1.16; 95% confidence interval [CI], 1.04-1.28) and in those requiring preoperative intensive support (RR=1.27; 95% CI, 1.15-1.41). Additional complications occurred in 16.3% of patients by 30 days, and overall 90-day mortality was 3.2% (95% CI, 2.7-3.7%). Co-occurrence of intraoperative hypotension, hypoxaemia, and anaemia was associated with increased risk of morbidity (RR=3.56; 95% CI, 1.64-7.71) and mortality (RR=19.80; 95% CI, 5.87-66.7). CONCLUSIONS: Variability in physiological thresholds that triggered an intervention, and the impact of poor tissue oxygenation on patient's outcome, highlight the need for more standardised perioperative management guidelines for neonates and infants.

Although poorly described in textbooks and rarely a topic of lecture, tracheal extubation is a critical phase of anesthetic care. It should therefore be carefully planned taking into account simple physiology-based principles to maintain the upper airway patent and avoid lung de-recruitment, but also the pharmacology of all anesthetic agents used. Although the management of most of its complications can be learned in a clinical simulation environment, the basic techniques can so far only be taught at the bedside, in the operating room. In this paper, the process of extubation is described in successive steps: preparation, return to adequate spontaneous ventilation, awake versus deep extubation, timing according to the child's breathing cycle, extubation in the operating room or in the Postanesthesia Care unit, child's management immediately after extubation, diagnosis and treatment of the early complications, and finally, how to prepare for a difficult reintubation.

INTRODUCTION: Protective ventilation is now a standard of care in adults. However, management of ventilation is heterogeneous in children and little is known regarding the mechanical ventilation parameters actually used during pediatric anesthesia. AIM: The aim of the study was to assess current ventilatory practices during pediatric anesthesia in France and to compare them with pediatric experts' statements, with a specific focus on tidal volume. PATIENTS AND METHODS: We conducted a prospective multicenter observational study, regarding the ventilatory management and the mechanical ventilation parameters, over two days (21 and 22 June 2017) in 29 pediatric centers in France. All children undergoing general anesthesia during these 2 days were eligible; those who required extracorporeal circulation or one-lung ventilation were excluded. RESULTS: A total of 701 children were included; median [IQR] age was 60 [24-120] months. Among the patients in whom controlled ventilation was used, 254/515 (49.3%) had an expired tidal volume >8 mL/kg and 44 children (8.8%) an expired tidal volume ≥10 mL/kg. Lower weight and use of a supraglottic airway device were significantly associated with provision of a tidal volume ≥10 mL/kg (odds ratio 0.94, 95% confidence interval [0.92; 0.97], P < .001 and 2.28 [1.20; 4.31], P = .012, respectively). The positive end-expiratory pressure was set at a median [IQR] of 4 [3-5] cmH2 O; it was <3 cmH2 O in 15.7% of children and not used in 56/499 (9.3%). Among intubated children, 57 (18.3%) received a tidal volume < 10 mL/kg with a positive end-expiratory pressure ≥3 cmH2 O in association with recruitment maneuvers. CONCLUSIONS: Ventilatory practices in children were heterogenous, and a large proportion of children were not ventilated as it is currently recommended by some experts.

OBJECTIVES: Cirrhotic children wait-listed for liver transplant are prone to bleeding from gastrointestinal varices. Grade 2-3 esophageal varices, red signs, and gastric varices are well-known risk factors. However, the involvement of hemostatic factors remains controversial because of the rebalanced state of coagulation during cirrhosis. METHODS: Children suffering from decompensated cirrhosis were prospectively included while being on waitlist. Portal hypertension was assessed by ultrasound and endoscopy. Coagulopathy was evaluated through conventional tests, thromboelastometry, and platelet function testing. The included children were followed up until liver transplantation, and all bleeding episodes were recorded. Children with or without bleeding were compared according to clinical, radiological, endoscopic, and biological parameters. In addition, validation of a predictive model for risk of variceal bleeding comprising of grade 2-3 esophageal varices, red spots, and fibrinogen level <150 mg/dL was applied on this cohort. RESULTS: Of 20 enrolled children, 6 had upper gastrointestinal bleeding. Significant differences were observed in fibrinogen level, adenosine diphosphate, and thrombin-dependent platelet aggregation. The model used to compute the upper gastrointestinal bleeding risk had an estimated predictive performance of 81.0%. Platelet aggregation analysis addition improved the estimated predictive performance up to 89.0%. CONCLUSIONS: We demonstrated an association between hemostatic factors and the upper gastrointestinal bleeding risk. A low fibrinogen level and platelet aggregation dysfunction may predict the risk of bleeding in children with decompensated cirrhosis. A predictive model is available to assess the upper gastrointestinal bleeding risk but needs further investigations. Clinicaltrials.gov number: NCT03244332.

BACKGROUND: Recently, the European prospective observational multicenter cohort study, APRICOT, reported anesthesia techniques and complications in more than 31 000 pediatric procedures. The main objective of this study was to analyze the current practice in regional anesthesia in the 33 countries that participated to APRICOT. METHODS: Data on regional anesthesia techniques were extracted from the database of APRICOT (261 centers across 33 European countries). All children, aged from birth to 16 years old, were eligible for inclusion during a 2-week period. Type of regional anesthesia, whether used awake or with sedation or general anesthesia, techniques of guidance, and the drugs administered were analyzed. RESULTS: Regional anesthesia was used in 4377 pediatric surgical procedures. The large majority was performed under general anesthesia with central blocks and truncal blocks, representing, respectively, 42.6% and 41.8% of performed techniques. Caudal blocks represented 76.9% of all central blocks. The penile and ilioinguinal/iliohypogastric blocks were the most commonly performed truncal blocks. Anesthetists used mainly anatomical landmarks; ultrasound guidance was applied in only 23.8% of cases. A wide variability of practices was observed in terms of regional anesthesia techniques and local anesthetics among the participating European countries. No serious complications were reported. CONCLUSION: These data show a large predominance of central and truncal blocks in APRICOT study. Ultrasound guidance was mainly used for peripheral nerve blocks while central blocks were performed using landmark techniques.

The growing number of medical procedures performed in children that require cooperation of patients, lack of movement, anxiolysis or/and analgesia triggers the increased need for procedural sedation. This document presents the consensus statement of the European Society for Paediatric Anaesthesiology about the principles connected with the safe management of procedural sedation and analgesia (PSA) by anaesthesiologists for elective procedures in children. It does not aim to provide a legal statement on how and by whom PSA should be performed. The document highlights that any staff taking part in sedation of children must be appropriately trained with the required competencies and must be able to demonstrate regularly that they have maintained their knowledge, skills and clinical experience. The main goal of creating this document was to reflect the opinions of the community of the paediatric anaesthesiologists in Europe regarding how PSA for paediatric patients should be organized to make it safe.

BACKGROUND: Ear, nose and throat (ENT) surgery, the most frequently performed surgical procedure in children, is a strong predictor for peri-operative respiratory complications. However, there is no clear information about peri-operative respiratory severe critical events (SCEs) associated with anaesthesia management of ENT children in Europe. OBJECTIVE: To characterise the epidemiology and incidence of respiratory SCEs during and following ENT surgery in Europe and to identify the risk factors for their occurrence. DESIGN: A secondary analysis of the Anaesthesia PRactice In Children Observational Trial, a prospective observational multicentre cohort trial. SETTING: The study included 261 centres across 33 European countries and took place over a consecutive 2-week recruitment period between April 2014 and January 2015. PATIENTS: We extracted data from 5592 ENT surgical procedures that were performed on 5572 children aged 6.0 (3.6) years (mean (SD)) from the surgical database and compared these with data from 15â952 non-ENT surgical children aged 6.7 (4.8) years. MAIN OUTCOME MEASURES: The primary outcome was the incidence of respiratory SCEs (laryngospasm, bronchospasm and new onset of postoperative stridor). Secondary outcomes were the differences in epidemiology between ENT children and non-ENT surgical children and the risk factors for the occurrence of respiratory SCEs. RESULTS: The incidence (95% confidence interval) of any respiratory SCE (laryngospasm, bronchospasm and postoperative stridor) was 3.93% (3.46 to 4.48) and was significantly higher than that observed in non-ENT surgical children [2.61% (2.37 to 2.87)], with a relative risk of 1.51 (1.28 to 1.77), P less than 0.0001. Younger age (14% decrease in critical events by increasing year, Pâ<â0.0001), history of snoring, recent upper respiratory tract infection and recent wheezing increased the risk of suffering a SCE by over two-fold (Pâ<â0.0001). There was also some evidence for a positive association with age below 4.6 years and lower surgical volume thresholds (<20 cases/2 weeks). CONCLUSION: The results of this study provide additional evidence for strong associations between risk factors and respiratory SCEs in children having ENT surgery. These observations may facilitate the implementation of good clinical practice recommendations for ENT patients in Europe. TRIAL REGISTRATION: ClinicalTrials.gov, number NCT01878760.

BACKGROUND: Better understanding of risk factors for adverse events during monitored anaesthesia care (MAC) for paediatric gastrointestinal endoscopy may improve outcome in children. OBJECTIVES: To identify the prevalence and predictors of adverse events during MAC for paediatric endoscopy. DESIGN: An observational study. SETTING: Tertiary university hospital, single-centre cohort, from January 2010 to August 2016. PATIENTS: The prospectively collected electronic anaesthetic records of 3435 children aged up to 16 years who underwent diagnostic gastrointestinal endoscopy under MAC were analysed retrospectively. Children with an American Society of Anesthesiologists' physical status at least 4, and those requiring mechanical ventilation and therapeutic or urgent endoscopy were excluded. MAIN OUTCOME MEASURES: The prevalence and predictors of adverse events during MAC for paediatric gastrointestinal endoscopy, with particular reference to the use of different anaesthetic or sedative agents. RESULTS: Meanâ±âSD age of the children was 8.5â±â4.4 years. The incidences of adverse events and adverse respiratory events were 3.4 and 3.3%, respectively. Multivariate analysis identified 12 independent predictors: age [odds ratio (OR) 0.92, Pâ=â0.002], children's size for example underweight (OR 1.78, Pâ=â0.039), overweight (OR 2.20, Pâ=â0.039), (morbid) obesity (OR 4.25, Pâ=â0.006), presence of respiratory comorbidities (OR 8.18, Pâ<â0.001), recent respiratory infection (OR 23.55, Pâ<â0.001) or both (OR 17.46, Pâ<â0.001), neurological comorbidities (OR 2.18, Pâ=â0.007), upper gastrointestinal endoscopy (OR 5.66, Pâ<â0.001), propofol co-administration with ketamine (OR 10.34, Pâ<â0. 001) or after sevoflurane induction (OR 44.95, Pâ<â0.001), and propofol induction dose (OR 18.97, Pâ<â0.001). Posthoc secondary analyses revealed a significantly higher risk of adverse events (OR 3.9, Pâ<â0.0001) and also significantly more respiratory comorbidities and respiratory infections (Pâ<â0.0001) in children aged less than 2 years when compared with children aged at least 2 years. No cardiovascular events were observed and outcome was uneventful. CONCLUSION: The present cohort demonstrated the feasibility and safety of MAC for paediatric gastrointestinal endoscopy by an experienced team. Although adverse events occurred rarely, their predictive factors were clinically identifiable. Applying this information in risk assessment and modifying anaesthetic management accordingly could improve outcome. TRIAL REGISTRATION: ISRCTN70362666.
