Early visual follow-up of preterm newborns by ophthalmologists makes it possible to identify the stage and grade of the disease and the indication of treatment or attendance of its evolution. Nursing orientation is essential to the PN relatives, since ROP is not an easily seen disease, so, parents being aware that the ophthalmologic follow-up is of vital importance for the visual recovery of the baby will make a difference in the child future visual health. Therefore, this study aims to evaluate the prevalence and evolution of ROP in PN, hospitalized in a Neonatal Intensive Care Unit (NICU) and attended at a referral ophthalmologic follow-up service. This is a quantitative, descriptive and exploratory study, carried out in the city of Cascavel. Data collection was done in medical records of PN, born between January 2014 and June 2016, hospitalized in the NICU of the West Paraná University hospital, and followed by the outpatient clinic of Cascavel Eyes Hospital, totaling 181 charts. A quantitative analysis was performed through descriptive and inferential statistic. The prevalence of ROP was 11.31% (n = 50). Relating its characteristics to evolution, the diagnoses prevalent in the PN of the study were respiratory diseases (41.99%) and among comorbidities, sepsis prevailed (63.54%). 80 PN required blood transfusion (44,20%) and 152 (83.98%) used oxygen therapy, with a predominance of mask device (n = 141; 77,90%) and orotracheal tube - TOT (n = 100; 55.25%), on average for 15 days. The highest concentration recorded was hood (45.0%). The time of use and the O2 concentration of TOT, time of mask use and time and concentration of O2 of Continuous Positive Airway Pressure (CPAP), were significant to trigger ROP. Among ROP cases, ten (5.5%) children had severe ROP and required laser treatment. All the PN diagnosed with ROP used oxygen. ROP prevailed in moderate preterm newborns (44%), with ROP grade 3 being the most severe, affecting both extreme and moderate PN. Respiratory diseases, sepsis and procedures such as blood transfusion and oxygen therapy influenced the presence of ROP, with prevalence in moderate preterm newborns. The adoption of ophthalmologic screening for ROP detection, with background examinations of the eyes in the NICU contributed to the early treatment and prevention of severe visual impairment and blindness caused by ROP. Thus, nurses are fundamentally important, from the prevention, the diagnosis until the course of the treatment and for discharge counselling. / A Retinopatia da Prematuridade (ROP) é uma enfermidade vasoproliferativa, relacionada à cegueira, em recém-nascidos prematuros (RNPT) que, dentre outros fatores, utilizaram oxigênio durante a hospitalização. O acompanhamento visual precoce de prematuros por oftalmologistas possibilita a identificação do estágio e do grau da doença, assim como a indicação de tratamento ou de acompanhamento da sua evolução. A orientação da enfermagem é primordial aos familiares dos RNPT, visto que a ROP não é uma doença de fácil visualização; portanto, os pais estarem cientes de que o acompanhamento oftalmológico é de vital importância para a recuperação visual do bebê fará diferença na vida futura da criança. Assim, este estudo objetiva avaliar a prevalência e a evolução da ROP em RNPT internados em uma Unidade de Terapia Intensiva Neonatal (UTIN) e acompanhados em serviço de seguimento oftalmológico de referência. Trata-se de uma pesquisa quantitativa, descritiva e exploratória, realizada no município de Cascavel. A coleta de dados ocorreu em prontuários de RNPT, nascidos entre janeiro de 2014 e junho de 2016, hospitalizados na UTIN do Hospital Universitário do Oeste do Paraná – HUOP, e em seguimento pelo ambulatório do Hospital de Olhos de Cascavel, totalizando 181 prontuários. Realizou-se análise quantitativa, por meio de estatística descritiva e inferencial. A prevalência de ROP foi de 11,31% (n=50). Relacionados às suas características e evolução, os diagnósticos prevalentes nos RNPT do estudo foram as doenças respiratórias (41,99%) e, entre as comorbidades, a sepse prevaleceu (63,54%). Necessitaram de transfusão de sangue 80 RNPT (44,20%), e 152 (83,98%) fizeram uso de oxigenioterapia, com predomínio do dispositivo máscara (n=141; 77,90%) e tubo orotraqueal - TOT (n=100; 55,25%), em média por 15 dias. A maior concentração registrada foi por halo (45%). O tempo de uso e a concentração de O2 de TOT, tempo de uso de máscara e tempo e concentração de O2 do Continuous Positive Airway Pressure (CPAP) foram significativos para desencadear a ROP. Dentre os casos de ROP, dez (5,5%) crianças tiveram ROP grave e necessitaram de tratamento com laser. Todos os RNPT diagnosticados com ROP fizeram uso de oxigênio. A ROP prevaleceu nos prematuros moderados (44%), sendo o grau 3 de ROP o mais grave encontrado, acometendo tanto RNPT extremos quanto moderados. Doenças respiratórias, sepse e procedimentos como a transfusão de sangue e a oxigenioterapia influenciaram na presença da ROP, com prevalência em prematuros moderados. A adoção da triagem oftalmológica para a detecção da ROP, com exames de fundo de olho sistematicamente realizados na UTIN, contribuíram para o tratamento precoce e a prevenção de deficiências visuais graves e cegueira causados pela ROP. Nesse sentido, o enfermeiro é de fundamental importância, desde a prevenção, o diagnóstico até o decorrer do tratamento e a alta.

Une morbidité et une mortalité néonatales élevées limitent l’efficacité du clonage somatique chez les bovins. Des malformations myoarthrosquelettiques, des anomalies ombilicales, des problèmes respiratoires et de la faiblesse ont été fréquemment observés chez les veaux clonés nouveaux-nés. Cette étude rétrospective porte sur 31 veaux clonés. Ses objectifs étaient de décrire les problèmes respiratoires rencontrés, leur évolution au cours du temps, les traitements instaurés pour soutenir la fonction respiratoire et la réponse aux traitements. Vingt-deux veaux ont souffert de problèmes respiratoires. La tachypnée, l’hypoxémie et l’hypercapnie sont les signes cliniques les plus fréquemment observés. L’analyse des gaz sanguins a été un outil essentiel dans le diagnostic et le suivi de la fonction respiratoire. La radiographie a permis une évaluation globale du poumon. L’oxygénothérapie intranasale et la ventilation mécanique ont permis de limiter la mortalité due à une insuffisance respiratoire à 18% (4/22). Cette étude a permis d’émettre des hypothèses quant à l’origine des problèmes respiratoires chez les veaux clonés. Plus d’une maladie semblent affecter les veaux clonés. La déficience en surfactant, l’hypertension pulmonaire persistante et le retard de résorption du fluide pulmonaire figurent parmi les entités pathologiques les plus probables. / High morbidity and mortality decrease the efficiency of somatic cell nuclear transfer. The main abnormalities observed in neonatal cloned calves are skeletal malformations, enlarged umbilical vessels, respiratory problems and weakness. This retrospective study involved 31 cloned calves. The objectives of this study were to describe the respiratory problems suffered by cloned calves during neonatal period, to assess their evolution, and to determine the possible causes. Secondary objectives were to describe the techniques used to assess and support respiratory function and the calves’ response. Respiratory problems affected 22 calves. Tachypnea, hypoxemia and hypercapnia were the most frequently observed signs. Arterial blood gas analyses and chest radiographs were precious to identify and assess respiratory problems. Intranasal oxygen and mechanical ventilation were efficient to limit mortality due to respiratory failure to 18% (4/22). It is plausible that more than one disease affect cloned calves. Delayed resorption of pulmonary fluid, persistent pulmonary hypertension and surfactant deficiency, or a combination of these factors, are among the most probable pathological entities.

Introduction:The management of patients with a tracheostomy tube is still current. It brings stress situation not only for the patients but also staff who care for them. This issue occurs across all disciplines. The aim of this study was to determine how they feel patients at the care of the tracheotomy while hospitalization of the intensive care unit. Methodology: The research was carried out during 2015 and 2016 at the surgical intensive care unit. The group of respondents consisted of patients with established tracheostomy tube. 80 pieces were distributed questionnaires, 73 patients responded return reached 91.25%. Results: The investigation showed that the comprehensive care of a tracheostomy for patients burdensome and unpleasant. Everyone clearly stated as the most annoying and most exhausting bother them forced to cough. 90,41% of patients reported that their aspiration meets at regular intervals to be able to prepare this fact. All of the respondents perform respiratory physiotherapy and 67.12% felt that they benefit. 95.89% of respondents suffer from a sense of social isolation. 82.19% would welcome the presence of a psychologist at the ICU. Group 80.82% think that it is adequately cared about their tracheostomy during hospitalization and all have the possibility of alternative communication.

The main objective of this research program was to assess the status of clinical knowledge and evidence-based practice in the medical management of mass casualties, contaminated by exposure to a chemical weapon, during a medical evacuation, which is defined as from the incident site of a contaminated environment up-to a clean zone. First, in our published systematic review, we assessed past medical responses during a chemical attack. The lack of clinical data and intervention-related information, such as protection and decontamination capabilities, stresses not only the need to study acute or prehospital settings, but also a set of integrated competences in the contaminated environment (i.e.: protection, decontamination and clinical interventions) (Prospero registered CRD42019104473). Second, a method paper which presents an ongoing international retro-prospective observational study on the medical responses during a chemical attack has been submitted for publication. The goal of this study is to describe the acute clinical management of patients in the contaminated zone (1970-2036; US Clinical trial registered NCT05026645). Data gathering is currently ongoing with the use of a comprehensive online registry programmed by the Quebec Respiratory Health Research Network. In the third and fourth, we started the development of two technological innovations to improve the medical management of mass casualties, caused by a chemical weapon, in contaminated environments. The first is the creation of a mobile laboratory for the continuity of our work in both indoor and outdoor settings. The other is the launch of a research program, named VIMY Multi-System, which includes: (1) An electronic casualty card system integrating the United Kingdom National Early Warning System; (2) a forward-deployable telemedicine capability prototype – currently undergoing integration testing – that incorporates drone technology to monitor patients being clinically managed in a simulated chemically contaminated environment. Our fifth published paper, on the methods of oxygen conservation with an automated titration system (n= 60; US Clinical trial registered NCT02782936 and NCT02809807), showed that such an automated system may constitute a viable medical solution for interventions in a contaminated environment and also constitutes one of the possible solutions to improve therapeutic interventions. The system studied allows the maintenance of adequate oxygenation while reducing the use of oxygen in patients, making it possible to extend their treatment duration even under conditions of limited logistical resources in oxygen. The oxygen flow provided by the automated system allows a mean reduction in administered oxygen quantities of more than six-fold when decreasing the prescribed SpO2 target from 98 to 90% (5 L/min to1 L/min, p <0.001) in hospitalized patients with respiratory disorders. The comparison was conducted on the basis of conservative flow rate targets reported in the literature (2.5, 5.0, 10.0 and 15.0 l/min). When it comes to the automated correction of a hypoxemic condition in sick patients and healthy subjects wearing a gas mask, the prescribed SpO2 target resulted in maximum administered oxygen flow rates of 0.2 L/min and 2.9 L/min respectively. These results show a possible logistic and therapeutic optimization in the use of oxygen. Finally, these initial advances will be integrated as our research work progresses in order to improve clinical evidence-based practices in contaminated environments due to the use of chemical weapons. / L’objectif principal de cette recherche était d’évaluer l’état des connaissances et le savoir-faire de la pratique clinique dans la gestion d’un grand nombre de blessés, contaminés des suites d’une exposition à l’arme chimique, pendant leur évacuation médicale depuis le site de l’incident dans un environnement contaminé jusqu’à la zone propre. Premièrement, dans une revue systématique que nous avons publiée, nous avons évalué les réponses médicales passées lors d’attaques chimiques. Le manque de données cliniques et d’autres informations liées à l’intervention, tel que les capacités de protection et de décontamination, souligne non seulement la nécessité d’étudier l’environnement préhospitalier, mais aussi la gamme de compétences interdépendantes en milieu contaminé (c.-à-d. : protection, décontamination et interventions cliniques) (Prospero CRD42019104473). Deuxièmement, nous avons soumis pour publication la méthodologie d’une étude rétroprospective observationnelle internationale s’intéressant aux réponses médicales lors d’une attaque chimique. Le but consiste à décrire la gestion clinique en soins aigus des blessés dans la zone contaminée (1970-2036) (ClinicalTrials.gov NCT05026645). L’acquisition de données est en cours à l’aide d’un registre de données intégral en ligne qui a été programmé par le Réseau de recherche en santé respiratoire du Québec. En troisième et quatrième lieu, nous avons entrepris le développement de deux innovations technologiques afin d’améliorer la prise en charge médicale des patients en milieu contaminé à la suite de l’utilisation de l’arme chimique. L’un est la création d’un laboratoire mobile pour poursuivre nos travaux tant à l’intérieur qu’à l’extérieur. L’autre est la mise sur pied d’un programme de recherche, nommé VIMY Multi-Systèmes, qui inclut : (1) un système de carte de blessés électronique intégrant le système national d’alerte précoce du Royaume-Uni, (2) les premiers tests d’intégration d’un prototype d’une capacité de télémédecine de déploiement avancé, incluant la technologie du drone, pour une surveillance clinique globale des patients pris en charge en milieu contaminé chimique simulé. Notre cinquième publication, qui porte sur les méthodes de maintien de l’oxygénation par titrage automatisée (n=60 ; ClinicalTrials.gov NCT02782936 et NCT02809807), nous a permis de démontrer qu’un système automatisé peut constituer une solution médicale intéressante qui serait applicable dans les interventions en milieu contaminé et de surcroît comme une solution pour améliorer les actions thérapeutiques. Le système que nous avons étudié permet de maintenir une oxygénation adéquate tout en limitant la consommation d’oxygène des patients, prolongeant ainsi leur durée de traitement, notamment en cas de ressources en oxygène limitées. D’une part, le débit de l’oxygène fourni par le système automatisé a permis une réduction moyenne des quantités administrées de l’ordre de plus de six fois lors de la diminution de la cible de saturation en oxygène (SpO2) prescrite de 98 à 90 % (5 L/min à 1 L/min, p < 0,001) chez les patients hospitalisés atteints de maladies respiratoires. La comparaison s’est faite par rapport à des débits conservateurs rapportés dans la littérature (2,5, 5,0, 10,0 et 15,0 L/min). D’autre part, la correction automatisée d’une condition hypoxémique chez les patients malades et les sujets sains portant le masque à gaz, la cible SpO2 a engendré des débits maximaux d’oxygènes administrés de 2,5 et 2,9 L/min respectivement. Ainsi, nous avons démontré une optimalisation logistique et thérapeutique de la consommation de l’oxygène. Finalement, ces premières avancées seront intégrées au fur et à mesure de l’avancement de nos recherches afin d’améliorer le processus de soins en milieu contaminé issu de l’utilisation de l’arme chimique.

Background Oxygen is one of the most commonly used drugs by anesthesiologists. The World Health Organization (WHO) gave recommendations regarding perioperative oxygen administration, but the practice of oxygen use in anesthesia, critical emergency, and intensive care medicine remains unclear. Methods We conducted an online survey among members of the European Society of Anaesthesiology and Intensive Care (ESAIC). The questionnaire consisted of 46 queries appraising the perioperative period, emergency medicine and in the intensive care, knowledge about current recommendations by the WHO, oxygen toxicity, and devices for supplemental oxygen therapy. Results Seven hundred ninety-eight ESAIC members (2.1% of all ESAIC members) completed the survey. Most respondents were board-certified and worked in hospitals with > 500 beds. The majority affirmed that they do not use specific protocols for oxygen administration. WHO recommendations are unknown to 42% of respondents, known but not followed by 14%, and known and followed by 24% of them. Respondents prefer inspiratory oxygen fraction (FiO2) ≥80% during induction and emergence from anesthesia, but intraoperatively < 60% for maintenance, and higher FiO2 in patients with diseased than non-diseased lungs. Postoperative oxygen therapy is prescribed more commonly according to peripheral oxygen saturation (SpO2), but shortage of devices still limits monitoring. When monitoring is used, SpO2 ≤ 95% is often targeted. In critical emergency medicine, oxygen is used frequently in patients aged ≥80 years, or presenting with respiratory distress, chronic obstructive pulmonary disease, myocardial infarction, and stroke. In the intensive care unit, oxygen is mostly targeted at 96%, especially in patients with pulmonary diseases. Conclusions The current practice of perioperative oxygen therapy among respondents does not follow WHO recommendations or current evidence, and access to postoperative monitoring devices impairs the individualization of oxygen therapy. Further research and additional teaching about use of oxygen are necessary.
