Anesthetic considerations in the perioperative management of the patient with Jarcho-Levin Syndrome.

Jarcho-Levin syndrome is an eponym used to describe a spectrum of small thoracic skeletal dysplasias with variable involvement of vertebrae and ribs. Initially considered lethal, it is currently compatible with life in its mildest forms. Bone alterations that lead to a restrictive respiratory pattern, recurrent respiratory infections and particular phenotype, can make perioperative anesthetic management difficult. The proper assessment of the airway is of special interest because it presents predictors of a difficult airway, as well as the prevention, early diagnosis and adequate treatment of respiratory failure. We present the case of a patient with Jarcho-Levin Syndrome who underwent vertebral distraction surgery, with its most notable implications in anesthetic management.

Factors associated with prolonged mechanical ventilation in children with pulmonary failure: Cohort study from the LARed Network registry.

OBJECTIVES: To identify factors associated with prolonged mechanical ventilation (pMV) in pediatric patients in pediatric intensive care units (PICUs). DESIGN: Secondary analysis of a prospective cohort. SETTING: PICUs in centers that are part of the LARed Network between April 2017 and January 2022. PARTICIPANTS: Pediatric patients on mechanical ventilation (IMV) due to respiratory causes. We defined IMV time greater than the 75th percentile of the global cohort. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Demographic data, diagnoses, severity scores, therapies, complications, length of stay, morbidity, and mortality. RESULTS: 1698 children with MV of 8±7 days were included, and pIMV was defined as 9 days. Factors related to admission were age under 6 months (OR 1.61, 95% CI 1.17-2.22), bronchopulmonary dysplasia (OR 3.71, 95% CI 1.87-7.36), and fungal infections (OR 6.66, 95% CI 1.87-23.74), while patients with asthma had a lower risk of pIMV (OR 0.30, 95% CI 0.12-0.78). Regarding evolution and length of stay in the PICU, it was related to ventilation-associated pneumonia (OR 4.27, 95% CI 1.79-10.20), need for tracheostomy (OR 2.91, 95% CI 1.89-4.48), transfusions (OR 2.94, 95% CI 2.18-3.96), neuromuscular blockade (OR 2.08, 95% CI 1.48-2.93), high-frequency ventilation (OR 2.91, 95% CI 1.89-4.48), and longer PICU stay (OR 1.13, 95% CI 1.10-1.16). In addition, mean airway pressure greater than 13cmH2O was associated with pIMV (OR 1.57, 95% CI 1.12-2.21). CONCLUSIONS: Factors related to IMV duration greater than 9 days in pediatric patients in PICUs were identified in terms of admission, evolution, and length of stay.

Risk factors for respiratory failure among hospitalized patients with Guillain-Barré syndrome.

BACKGROUND: Guillain-Barré syndrome (GBS) is an acute inflammatory polyneuropathy that can lead to respiratory failure. In this study, we evaluate early clinical risk factors for respiratory failure at the time of hospital admission. METHODS: We studied a retrospective cohort of patients with GBS admitted to a tertiary care center. The potential risk factors studied were sociodemographic characteristics, GBS symptoms, overall and cervical muscle weakness (Medical Research Council [MRC] scores), electromyography findings, and cerebrospinal fluid analysis findings. Unadjusted odds ratios (OR) were calculated and exact logistic regression analysis (adjusted OR) performed to assess the association between baseline risk factors and respiratory failure. RESULTS: Overall, 13 of 113 (12%) patients included in the study developed respiratory failure. Unadjusted analyses showed that involvement of any cranial nerve (OR: 14.7; 95% CI, 1.8-117.1), facial palsy (OR: 17.3; 95% CI, 2.2-138.0), and bulbar weakness (OR: 10.7; 95% CI, 2.3-50.0) were associated with increased risk of respiratory failure. Lower MRC sum scores (for scores <30, OR: 14.0; 95% CI, 1.54-127.2) and neck MRC scores (for scores ≤3, OR: 21.0; 95% CI, 3.5-125.2) were associated with higher likelihood of respiratory failure. Adjusted analyses showed that presence of bulbar weakness (OR: 7.6; 95% CI, 1.3-43.0) and low neck MRC scores (scores ≤3, OR: 9.2; 95% CI, 3.5-125.2, vs scores >3) were independently associated with respiratory failure. CONCLUSIONS: Bulbar and neck muscle weakness at admission are clinical predictors of increased risk of respiratory failure in patients with GBS. These findings could guide the adequate management of high-risk patients.

Neumonía de organización como causa de hipoxemia persistente a la tercera semana de infección por SARS-CoV-2. Reporte de caso / Organization pneumonia as a cause of persistent hypoxemia in the third week of SARS CoV-2 infection, case report

El Coronavirus 2 es un betacoronavirus de ARN responsable de la enfermedad por coronavirus 2019 (COVID-19). Fue detectado por primera vez en Wuhan, China y se propagó rápidamente a nivel mundial, llevando a la OMS a declarar una pandemia en marzo de 2020. Para julio de 2021, se habían registrado casi 196 millones de casos confirmados de COVID-19, siendo responsable de más de cuatro millones de muertes en todo el mundo. En la mayoría de los casos, los pacientes presentan síntomas respiratorios que van desde leves hasta graves, pudiendo desencadenar lesiones pulmonares agudas y disfunción multiorgánica; incluso se han reportado casos de hipoxemia refractaria, lo que implica una elevada morbimortalidad. Las posibles causas incluyen infecciones secundarias, enfermedad tromboembólica pulmonar, fibrosis pulmonar y reinfección por SARS-CoV-2. En pacientes con COVID-19 se ha observado la neumonía de organización como una complicación en la fase subaguda y tardía de la enfermedad, desencadenando un deterioro clínico y radiológico significativo. El tratamiento con glucocorticoides ha mostrado una respuesta favorable en estos casos. Presentamos un caso de neumonía de organización relacionado con la infección por SARS-CoV-2 que, aunque no contó con confirmación histológica, la integración de la presentación clínica, la evolución y los hallazgos radiológicos permitieron realizar la aproximación diagnóstica, destacando la importancia del manejo adecuado con glucocorticoides en estos casos. Sin embargo, se necesitan más estudios para evaluar el desarrollo de esta complicación en una población más amplia.

Coronavirus 2 is an RNA beta coronavirus responsible for coronavirus disease 2019 (COVID-19). It was first detected in Wuhan, China, and spread rapidly globally, leading the WHO to declare a pandemic in March 2020. By July 2021, there had been nearly 196 million confirmed cases, being responsible for more than four million deaths worldwide. In most cases, patients present with respiratory symptoms ranging from mild to severe, which can lead to acute lung lesions and multi-organ dysfunction; cases of refractory hypoxemia have even been reported, which implies high morbidity and mortality. Possible causes include secondary infections, pulmonary thromboembolic disease, pulmonary fibrosis, and SARS-CoV-2 reinfection. Most COVID-19 patients exhibit respiratory symptoms, ranging from mild to severe, with the potential for acute lung injuries and multiorgan dysfunction leading to high mortality. Cases of refractory hypoxemia in COVID-19 patients have been reported, indicating significant morbidity and mortality. Possible causes include secondary infections, pulmonary thromboembolism, pulmonary fibrosis, and reinfection by SARS-CoV-2. In patients with COVID-19, organization pneumonia has been observed as a complication in the subacute and late phase of the disease, triggering significant clinical and radiological deterioration. Treatment with glucocorticoids has shown a favorable response in these cases. We present a case of organizing pneumonia in relation SARS-CoV-2 infection that, although it did not have histological confirmation, the clinical presentation, evolution and radiological findings allowed a diagnostic approach, highlighting the importance of proper management with glucocorticoids in these cases. However, more studies are needed to evaluate the development of this complication in a larger population.

Switches in non-invasive respiratory support strategies during acute hypoxemic respiratory failure: Need to monitoring from a retrospective observational study.

OBJECTIVE: To explore combined non-invasive-respiratory-support (NIRS) patterns, reasons for NIRS switching, and their potential impact on clinical outcomes in acute-hypoxemic-respiratory-failure (AHRF) patients. DESIGN: Retrospective, single-center observational study. SETTING: Intensive Care Medicine. PATIENTS: AHRF patients (cardiac origin and respiratory acidosis excluded) underwent combined NIRS therapies such as non-invasive-ventilation (NIV) and High-Flow-Nasal-Cannula (HFNC). INTERVENTIONS: Patients were classified based on the first NIRS switch performed (HFNC-to-NIV or NIV-to-HFNC), and further specific NIRS switching strategies (NIV trial-like vs. Non-NIV trial-like and single vs. multiples switches) were independently evaluated. MAIN VARIABLES OF INTEREST: Reasons for switching, NIRS failure and mortality rates. RESULTS: A total of 63 patients with AHRF were included, receiving combined NIRS, 58.7% classified in the HFNC-to-NIV group and 41.3% in the NIV-to-HFNC group. Reason for switching from HFNC to NIV was AHRF worsening (100%), while from NIV to HFNC was respiratory improvement (76.9%). NIRS failure rates were higher in the HFNC-to-NIV than in NIV-to-HFNC group (81% vs. 35%, p < 0.001). Among HFNC-to-NIV patients, there was no difference in the failure rate between the NIV trial-like and non-NIV trial-like groups (86% vs. 78%, p = 0.575) but the mortality rate was significantly lower in NIV trial-like group (14% vs. 52%, p = 0.02). Among NIV to HFNC patients, NIV failure was lower in the single switch group compared to the multiple switches group (15% vs. 53%, p = 0.039), with a shorter length of stay (5 [2-8] vs. 12 [8-30] days, p = 0.001). CONCLUSIONS: NIRS combination is used in real life and both switches' strategies, HFNC to NIV and NIV to HFNC, are common in AHRF management. Transitioning from HFNC to NIV is suggested as a therapeutic escalation and in this context performance of a NIV-trial could be beneficial. Conversely, switching from NIV to HFNC is suggested as a de-escalation strategy that is deemed safe if there is no NIRS failure.

Pleuropulmonary and diaphragmatic ultrasound in intensive care medicine.

The usefulness of ultrasound for chest exploration was described in 1968. It was not until the 1990s, when its use became widespread in Intensive Care Units as a diagnostic, monitoring and procedural guide tool. The fact that it is a non-invasive tool, accessible at the bedside, with a sensitivity and specificity close to computerized tomography (CT) and with a short learning curve, have made it a mandatory technique in the management of critically ill patients. It is essential to know that there are different air/fluid ratio generated by different pathologies that gives rise to one echographic pattern or another. The identification of these patterns together with the clinical information will allow to make an accurate diagnosis in most settings of respiratory failure. Likewise, we must not forget the importance of evaluating diaphragmatic function by ultrasound during weaning from mechanical ventilation.

Accuracy of the persistent AKI risk index in predicting acute kidney injury in patients admitted to the intensive care unit for acute respiratory failure / Acurácia do persistent AKI risk index na predição de injúria renal aguda em pacientes admitidos na unidade de terapia intensiva por insuficiência respiratória aguda

ABSTRACT Objective: To evaluate the accuracy of the persistent AKI risk index (PARI) in predicting acute kidney injury within 72 hours after admission to the intensive care unit, persistent acute kidney injury, renal replacement therapy, and death within 7 days in patients hospitalized due to acute respiratory failure. Methods: This study was done in a cohort of diagnoses of consecutive adult patients admitted to the intensive care unit of eight hospitals in Curitiba, Brazil, between March and September 2020 due to acute respiratory failure secondary to suspected COVID-19. The COVID-19 diagnosis was confirmed or refuted by RT-PCR for the detection of SARS-CoV-2. The ability of PARI to predict acute kidney injury at 72 hours, persistent acute kidney injury, renal replacement therapy, and death within 7 days was analyzed by ROC curves in comparison to delta creatinine, SOFA, and APACHE II. Results: Of the 1,001 patients in the cohort, 538 were included in the analysis. The mean age was 62 ± 17 years, 54.8% were men, and the median APACHE II score was 12. At admission, the median SOFA score was 3, and 83.3% had no renal dysfunction. After admission to the intensive care unit, 17.1% had acute kidney injury within 72 hours, and through 7 days, 19.5% had persistent acute kidney injury, 5% underwent renal replacement therapy, and 17.1% died. The PARI had an area under the ROC curve of 0.75 (0.696 - 0.807) for the prediction of acute kidney injury at 72 hours, 0.71 (0.613 - 0.807) for renal replacement therapy, and 0.64 (0.565 - 0.710) for death. Conclusion: The PARI has acceptable accuracy in predicting acute kidney injury within 72 hours and renal replacement therapy within 7 days of admission to the intensive care unit, but it is not significantly better than the other scores.

RESUMO Objetivo: Avaliar a acurácia do persistent AKI risk index (PARI) na predição de injúria renal aguda em 72 horas após a admissão em unidade de terapia intensiva, injúria renal aguda persistente, terapia de substituição renal e óbito, em até 7 dias em pacientes internados por insuficiência respiratória aguda. Métodos: Estudo de método-diagnóstico com base em coorte de inclusão consecutiva de pacientes adultos internados em unidade de terapia intensiva de oito hospitais de Curitiba (PR) entre março e setembro de 2020, por insuficiência respiratória aguda secundária à suspeita de COVID-19, com confirmação ou refutação diagnóstica dada pelo resultado de RT-PCR para detecção do SARS-CoV-2. O potencial preditor do PARI foi analisado por curva ROC em relação a delta creatinina, SOFA e APACHE II, para os desfechos injúria renal aguda em 72 horas; injúria renal aguda persistente; terapia de substituição renal e mortalidade em até 7 dias. Resultados: Dos 1.001 pacientes da coorte, 538 foram incluídos na análise. A média de idade foi de 62 ± 17 anos, 54,8% eram homens e o APACHE II mediano foi de 12. Na admissão, o SOFA mediano era 3, e 83,3% não apresentavam disfunção renal. Após admissão na unidade de terapia intensiva, 17,1% apresentaram injúria renal aguda em 72 horas e, até o sétimo dia, 19,5% apresentaram injúria renal aguda persistente, 5% realizaram terapia de substituição renal, e 17,1% foram a óbito. O PARI apresentou área sob a curva ROC de 0,75 (0,696 - 0,807) para predição de injúria renal aguda em 72 horas, 0,71 (0,613 - 0,807) para terapia de substituição renal e 0,64 (0,565 - 0,710) para mortalidade. Conclusão: O PARI tem acurácia aceitável na predição de injúria renal aguda em 72 horas e terapia de substituição renal em até 7 dias da admissão na unidade de terapia intensiva, porém sem diferença significativa dos demais escores.

Impact of viral detection in patients with community-acquired pneumonia: An observational cohort study.

PURPOSE: The presence of a respiratory virus in patients with community-acquired pneumonia (CAP) may have an impact on the bacterial etiology and clinical presentation. In this study we aimed to assess the role of viral infection in the bacterial etiology and outcomes of patients with CAP. METHODS: We performed a retrospective study of all adults hospitalized with CAP between November 2017 and October 2018. Patients were classified according to the presence of viral infection. An unvaried and a multivaried analysis were performed to identify variables associated with viral infection and clinical outcomes. RESULTS: Overall 590 patients were included. A microorganism was documented in 375 cases (63.5%). A viral infection was demonstrated in 118 (20%). The main pathogens were Streptococcus pneumoniae (35.8%), Staphylococcus aureus (2.9%) and influenza virus (10.8%). A trend to a higher rate of S. aureus (p=0.06) in patients with viral infection was observed. Patients with viral infection had more often bilateral consolidation patterns (17.8% vs 10.8%, p=0.04), respiratory failure (59.3% vs 42.8%, p=0.001), ICU admission (17.8% vs 7%, p=0.001) and invasive mechanical ventilation (9.3% vs 2.8%, p=0.003). Risk factors for respiratory failure were chronic lung disease, age >65 years, positive blood cultures and viral infection. Influenza, virus but no other respiratory viruses, was associated with respiratory failure (OR, 3.72; 95% CI, 2.06-6.73). CONCLUSIONS: Our study reinforces the idea that co-viral infection has an impact in the clinical presentation of CAP causing a more severe clinical picture. This impact seems to be mainly due to influenza virus infection.

Role of ultrasound in acute respiratory failure and in the weaning of mechanical ventilation.

Comprehensive ultrasound assessment has become an essential tool to facilitate the diagnosis and therapeutic management of critically ill patients with acute respiratory failure (ARF). There is evidence supporting the use of ultrasound for the diagnosis of pneumothorax, acute respiratory distress syndrome, cardiogenic pulmonary edema, pneumonia and acute pulmonary thromboembolism, and in patients with COVID-19. In addition, in recent years, the use of ultrasound to evaluate responses to treatment in critically ill patients with ARF has been developed, providing a noninvasive tool for titrating positive end-expiratory pressure, monitoring recruitment maneuvers and response to prone position, as well as for facilitating weaning from mechanical ventilation. The objective of this review is to summarize the basic concepts on the utility of ultrasound in the diagnosis and monitoring of critically ill patients with ARF.

Split cricoideo anterior posterior: una novedosa técnica para evitar la traqueotomía en parálisis cordal bilateral en pacientes pediátricos / Posterior anterior cricoid split: a cutting-edge technique to avoid tracheostomy in bilateral cordal paralysis in pediatric patients

Introducción: La parálisis cordal bilateral en aducción es la segunda causa de estridor congénito y genera una grave obstrucción de la vía aérea, debutando con estridor. La traqueotomía ha sido durante mucho tiempo el gold estándar para el tratamiento de esta afección, no exenta de complicaciones. Existen procedimientos que intentan evitar la traqueotomía, como el split cricoideo anterior posterior endoscópico (SCAPE). Objetivo: Presentar experiencia con SCAPE en pacientes pediátricos como tratamiento alternativo de parálisis cordal bilateral en aducción. Material y Método: Análisis retrospectivo de los resultados quirúrgicos obtenidos en pacientes con parálisis cordal bilateral en aducción tratados con SCAPE entre enero de 2016 y diciembre de 2019 en el Hospital Guillermo Grant Benavente de Concepción, Chile. Resultados: Siete pacientes se sometieron a SCAPE. Todos los pacientes presentaban insuficiencia respiratoria severa, cinco requirieron asistencia ventilatoria mecánica. Seis pacientes tenían el diagnóstico de parálisis cordal bilateral (PCB) congénita y uno PCB secundaria a tumor de tronco cerebral. Cuatro pacientes presentaron comorbilidad de la vía aérea: dos pacientes presentaron estenosis subglótica grado I y dos pacientes presentaron laringomalacia que requirió manejo quirúrgico. Los días promedio de intubación fueron once días. Ningún paciente requirió soporte ventilatorio postoperatorio, sólo un paciente recibió oxigenoterapia nocturna debido a hipoventilación secundaria a lesión de tronco. Ningún paciente ha presentado descompensación respiratoria grave. Un 40% ha recuperado movilidad cordal bilateral. Conclusión: Split cricoideo anteroposterior endoscópico es una alternativa eficaz para tratar el PCB en pacientes pediátricos. Nuestro estudio evidencia que es una alternativa a la traqueotomía, con excelentes resultados y menor morbimortalidad.

Introduction: Bilateral vocal fold paralysis in adduction is the second cause of congenital stridor and generates a serious obstruction of the airway. Tracheostomy has long been the gold standard for the treatment of this condition, but it has inherent complications. There are procedures that try to avoid tracheotomy, such as the endoscopic anterior posterior cricoid split (EAPCS). Aim: Present our experience with EAPCS in pediatric patients as a treatment for bilateral vocal fold paralysis in adduction. Material and Method: Retrospective analysis of the surgical results obtained in patients with bilateral vocal cord paralysis in adduction treated with EAPCS between January 2016 and December 2019 at Guillermo Grant Benavente Hospital in Concepción, Chile. Results: Seven patients underwent EAPCS. All patients had severe respiratory failure, five required mechanical ventilation assistance. Six patients were diagnosed with congenital bilateral cord palsy (BCP) and one BCP secondary to a brainstem tumor. Four patients had airway comorbidity: two patients had grade I subglottic stenosis and two patients had laryngomalacia that required surgical management. The average days of intubation were eleven days. No patient required post op invasive/non-invasive ventilation, only one patient received nocturnal oxygen therapy due to hypoventilation secondary to trunk injury. None of the patients has presented severe respiratory decompensation. Forty percent have recovered bilateral chordal mobility. Conclusion: SCAPE is a cutting-edge and effective alternative to treat PCB in pediatric patients. Our study shows that it is an alternative to tracheotomy, with excellent results and lower morbidity and mortality.

The role of corticosteroids in patients hospitalized for COVID-19 at Mexico general Hospital.

OBJECTIVE: To compare the evolution of hospitalized patients infected with SARS-CoV-2 who received corticosteroid-based treatment versus patients who received standard therapy. METHOD: Retrospective, observational, and analytical study. Clinical records were collected from the different intensive care units, and data were obtained from confirmed COVID-19 patients over 18 years of age who were hospitalized. The population was divided into two groups: patients who received corticosteroid treatment, and those who received standard therapy. RESULTS: A total of 1603 patients were admitted to hospital, and of these 984 (62.9%) were discharged due to death. The main result was the identification by odds ratio (OR: 4.68; 95% confidence interval [95% CI]: 3.75-5.83; p = 0.001) as risk for death to the use of systemic steroids, as well as the use of invasive mechanical ventilation (OR: 2.26; 95% CI: 1.80-2.82; p < 0.001). The male gender was the most affected with 1051 (65.6%) patients. Mean age was 56 years (± 14). CONCLUSIONS: Corticosteroid use was associated with poor prognosis in patients hospitalized for COVID-19 compared to those receiving standard therapy.

OBJETIVO: Comparar la evolución de los pacientes hospitalizados infectados por SARS-CoV-2 que recibieron tratamiento a base de corticoesteroides frente a los pacientes que recibieron la terapia estándar. MÉTODO: Estudio de tipo retrospectivo, observacional y analítico. Se recolectaron los expedientes clínicos de las diferentes unidades de terapia intensiva y se obtuvieron datos de los pacientes confirmados de COVID-19, mayores de 18 años, que estuvieron hospitalizados. Se dividió la población en dos grupos: pacientes que recibieron tratamiento con corticoesteroides y pacientes que recibieron terapia estándar. RESULTADOS: De un total de 1603 pacientes ingresados a hospitalización, 984 (62.9%) fallecieron. El resultado principal fue la identificación mediante razón de momios (odds ratio [OR]: 4.68; intervalo de confianza del 95% [IC95%]: 3.75-5.83; p = 0.001) como riesgo para defunción con uso de esteroides sistémicos, así como con uso de ventilación mecánica invasiva (OR: 2.26; IC95%: 1.80-2.82; p < 0.001). El sexo masculino fue el más afectado, con 1051 (65.6%) pacientes. La media de edad fue de 56 años (± 14). CONCLUSIONES: El uso de corticoesteroides se asoció con mal pronóstico en los pacientes hospitalizados por COVID-19, en comparación con los que recibieron la terapia estándar.

Introducción: La ingestión de queroseno conduce a la aparición de diversas complicaciones. Dada su baja viscosidad, en el sistema respiratorio es capaz de llegar a las vías aéreas distales y provocar lesión pulmonar, lo cual requiere atención urgente. La ecografía pulmonar, en la emergencia médica es un pilar que ha aumentado la capacidad de diagnóstico, guía la toma de decisiones y permite estratificar el pronóstico del paciente. Objetivo: Presentar un paciente con neumonitis química por aspiración de queroseno, sus características clínicas y procedimiento ecográfico pulmonar empleado. Caso clínico: Paciente masculino de 68 años de edad con antecedentes de alcoholismo y epilepsia, que hace tratamiento irregular. Asistió al servicio de urgencias con dificultad respiratoria de varios días de evolución y el precedente de ingesta de queroseno, con broncoaspiración. Se le realizó ecografía pulmonar, según el protocolo Bedside Lung Ultrasound in Emergency; se observó síndrome intersticio alveolar grave, engrosamiento de la línea pleural, microconsolidaciones subpleurales y pérdida grave de la aireación pulmonar. Se le instauró tratamiento con ventilación mecánica invasiva y antibiótico terapia; mejoró el puntaje de aireación pulmonar y el paciente se recuperó. Conclusiones: La insuficiencia respiratoria aguda secundaria a neumonitis química por queroseno, es una entidad clínica compleja en su evaluación; el uso de la ecografía pulmonar constituye una herramienta vital que permite valorar en tiempo real el parénquima pulmonar y la pleura, para tomar decisiones terapéuticas oportunas y precisas.

Introduction: The ingestion of kerosene leads to the appearance of various complications. Given its low viscosity, in the respiratory system, it is capable of reaching the distal airways and causing lung injury, which requires urgent attention. Lung ultrasound, in medical emergencies, is a pillar that has increased diagnostic capacity, guides decision-making and allows stratifying the patient's prognosis. Objective: To present a patient with chemical pneumonitis due to aspiration of kerosene, its clinical characteristics and pulmonary ultrasound procedure used. Clinical case: 68-year-old male patient with a history of alcoholism and epilepsy, which undergoes irregular treatment. He attended Emergency with respiratory distress of several days of evolution and the precedent of ingestion of kerosene, with bronchial aspiration. Lung ultrasound was performed, according to the Bedside Lung Ultrasound in Emergency protocol; severe alveolar interstitial syndrome, thickening of the pleural line, subpleural micro-consolidations, and severe loss of pulmonary aeration were observed. Treatment with invasive mechanical ventilation and antibiotic therapy was established; the pulmonary aeration score improved, and the patient recovered. Conclusions: Acute respiratory failure secondary to chemical pneumonitis due to kerosene is a complex clinical entity in its evaluation; the use of lung ultrasound is a vital tool that allows the lung parenchyma and pleura to be assessed in real time, in order to make timely and precise therapeutic decisions.

Avaliação do uso de estratégias não invasivas em pacientes com insuficiência respiratória por COVID-19 / Evaluation of the use of non-invasive strategies in patients with respiratory failure by COVID-19

Introdução: Durante a pandemia de COVID-19, tornou-se necessário o uso de estratégias no tratamento dos pacientes que evoluem com insuficiência respiratória aguda. Objetivo: Avaliar o uso de estratégias não invasivas no desfecho de pacientes com insuficiência respiratória aguda ou crônica agudizada por COVID-19. Métodos: Pesquisa de caráter observacional e retrospectivo por meio da coleta de dados em prontuário eletrônico com pacientes submetidos ao uso de cânula nasal de alto fluxo (CNAF) e/ou ventilação mecânica não invasiva (VNI). Resultados: 81 pacientes, sendo 70,4% (57) do sexo masculino, com 56,5 ± 14,6 anos. 49,4% (40) dos indivíduos fizeram uso de CNAF e VNI, 9,9% (8) e 40,7% (33) apenas VNI ou CNAF, respectivamente. O tempo médio de uso da CNAF foi de 4,4 ± 3,7 dias e de VNI foi de 2,7 ± 3,4 dias. Observou-se que 43 (53,1%) dos pacientes pesquisados evoluíram para intubação orotraqueal (IOT) e 40 (49,4%) para óbito. Destes, 22 encontravam-se em IOT. Houve diferença estatística quando comparados idade entre os grupos IOT e não IOT, 60,5 ± 13,9 anos vs 52,1 ± 14,2 anos (p = 0,012), respectivamente. Conclusão: O uso de VNI e/ou CNAF pode ser considerado como alternativa no tratamento de pacientes com COVID-19. Contudo, os diversos fatores intrínsecos e extrínsecos ao paciente ainda contribuem para a alta taxa de IOT e de mortalidade.

Multidisciplinary approach of the sequelae one month after hospital discharge in patients with severe bilateral COVID-19 pneumonia, are there differences depending on the respiratory therapy used during admission to intensive care?

OBJECTIVE: To describe the sequelae one month after hospital discharge in patients who required admission to Intensive Care for severe COVID 19 pneumonia and to analyze the differences between those who received therapy exclusively with high-flow oxygen therapy compared to those who required invasive mechanical ventilation. DESIGN: Cohort, prospective and observational study. SETTING: Post-intensive care multidisciplinary program. PATIENTS OR PARTICIPANTS: Patients who survived admission to the intensive care unit (ICU) for severe COVID 19 pneumonia from April 2020 to October 2021. INTERVENTIONS: Inclusion in the post-ICU multidisciplinary program. MAIN VARIABLES OF INTEREST: Motor, sensory, psychological/psychiatric, respiratory and nutritional sequelae after hospital admission. RESULTS: 104 patients were included. 48 patients received high-flow nasal oxygen therapy (ONAF) and 56 invasive mechanical ventilation (IMV). The main sequelae found were distal neuropathy (33.9% IMV vs 10.4% ONAF); brachial plexopathy (10.7% IMV vs 0% ONAF); decrease in grip strength: right hand 20.67kg (±8.27) in VMI vs 31.8kg (±11.59) in ONAF and left hand 19.39kg (±8.45) in VMI vs 30.26kg (±12.74) in ONAF; and limited muscle balance in the lower limbs (28.6% VMI vs 8.6% ONAF). The differences observed between both groups did not reach statistical significance in the multivariable study. CONCLUSIONS: The results obtained after the multivariate study suggest that there are no differences in the perceived physical sequelae one month after hospital discharge depending on the respiratory therapy used, whether it was high-flow nasal oxygen therapy or prolonged mechanical ventilation, although more studies are needed to be able to draw conclusions.

Compromiso del parénquima pulmonar secundaria a la inyección subcutánea de geles de silicona: reporte de caso

El compromiso del parénquima pulmonar secundario a la inyección subcutánea de geles de silicona es un cuadro de presentación excepcional, que se presenta con mayor frecuencia en mujeres entre los 22 a 55 años. Aunque se han planteado distintas teorías sobre su etiología, esta se desconoce y puede presentar complicaciones locales, sistémicas e incluso tener un desenlace fatal. Son pocos los casos reportados en América del Sur, y en el Perú no existe reporte alguno de esta singular entidad. Se presenta el caso de un paciente varón de 28 años, transexual, previamente sano, quien tras la inyección subcutánea de geles de silicona en la región glútea, en forma ilegal y por una persona que no es profesional de la salud, manifestó, dentro de las primeras 24 horas, un cuadro clínico caracterizado por dificultad respiratoria progresiva y dolor torácico punzante de aproximadamente 7 de 10 en la escala del dolor. Al ingresar a emergencias se evidenció de manera objetiva insuficiencia respiratoria, ya que el paciente presentó una saturación de oxígeno del 72 % a Fio₂: 21 %, asimismo, el compromiso del parénquima pulmonar tanto en la tomografía y radiografía de tórax con signos muy sugerentes de esta patología. Mediante la prueba ARN para SARS-CoV-2 en la muestra respiratoria por RT-PCR en tiempo real se descartó la neumonía secundaria al virus SARS-CoV-2, igualmente se excluyó la patología por inmunosupresión y tromboembolismo pulmonar. Debido a que no existe un tratamiento estandarizado se le brindó las medidas de soporte pertinentes, tales como administración de oxígeno suplementario a bajo flujo por cánula binasal, corticoides sistémicos vía endovenosa, además de antibioticoterapia, y se logró una evolución favorable con resolución del cuadro clínico inicial. Después de 10 días de tratamiento intrahospitalario el paciente fue dado de alta.

Pulmonary parenchymal involvement secondary to the subcutaneous injection of silicone gels is an unusual condition which occurs more frequently in women aged between 22 and 55 years. Although different theories have been put forward about its etiology, it is unknown and the condition may cause local and systemic complications and even have a fatal outcome. Few cases have been reported in South America and there is no report of this unique entity in Peru. We present the case of a previously healthy 28-year-old male transgender patient who, after an illegal subcutaneous injection of silicone gels in the gluteal region given by a non-healthcare professional, showed progressive respiratory distress and stabbing chest pain of approximately 7 out of 10 on the pain scale within the first 24 hours. Upon admission to the emergency room, respiratory failure was objectively evidenced since the patient had an oxygen saturation of 72 % at a FiO₂ of 21 %, as well as pulmonary parenchymal involvement both in the CT scan and chest X-ray with signs highly suggestive of this pathology. Using a SARS-CoV-2 RNA real-time RT-PCR test performed on a respiratory specimen, COVID pneumonia, immunodeficiency disorders and pulmonary embolism were ruled out. Since there is no standard treatment, the patient was given relevant support measures such as the administration of supplemental oxygen at a low flow rate by binasal cannula, intravenous systemic corticosteroids and antibiotic therapy, thus achieving good progress with resolution of the initial clinical presentation. Then, after 10 days of intrahospital treatment, the patient was discharged.

Clinical outcomes according to timing to invasive ventilation due to noninvasive ventilation failure in children.

OBJECTIVE: Noninvasive ventilation (NIV) failure it has been associated to worst clinical outcomes due to a delay in intubation and initiation of invasive mechanical ventilation (IMV). There is a lack of evidence in pediatric patients regarding this topic. The objective was to deter-mine the association between duration of IMV and length of stay, with duration of NIV prior tointubation/IMV in pediatric patients. DESIGN: A prospective cohort study since January 2015 to October 2019. SETTING: A pediatric intensive care unit. PATIENTS: Children under 15 years with acute respiratory failure who failed to noninvasive ventilation. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Demographic variables, pediatric index of mortality (PIM2), pediatric acute respiratory distress syndrome (PARDS) diagnosis, IMV and NIV duration, PICU LOS were registered and intrahospital mortality. RESULTS: A total of 109 patients with a median (IQR) age of 7 (3-14) months were included. The main diagnosis was pneumonia (89.9%). PARDS was diagnosed in 37.6% of the sample. No association was found between NIV duration and duration of IMV after Kaplan-Meier analysis (Log rank P = .479). There was no significant difference between PICU LOS (P = .253) or hospital LOS (P = 0.669), when categorized by NIV duration before intubation. PARDS diagnosis was associated to an increased length of invasive ventilation (HR: 0.64 [95% IC: 0.42-0.99]). CONCLUSIONS: No association was found between NIV duration prior to intubation and duration of invasive ventilation in critical pediatric patients with acute respiratory failure.

Airways management in SARS-COV-2 acute respiratory failure: A prospective observational multi-center study.

OBJECTIVE: Few studies have reported the implications and adverse events of performing endotracheal intubation for critically ill COVID-19 patients admitted to intensive care units. The aim of the present study was to determine the adverse events related to tracheal intubation in COVID-19 patients, defined as the onset of hemodynamic instability, severe hypoxemia, and cardiac arrest. SETTING: Tertiary care medical hospitals, dual-centre study performed in Northern Italy from November 2020 to May 2021. PATIENTS: Adult patients with positive SARS-CoV-2 PCR test, admitted for respiratory failure and need of advanced invasive airways management. INTERVENTIONS: Endotracheal Intubation Adverse Events. MAIN VARIABLES OF INTERESTS: The primary endpoint was to determine the occurrence of at least 1 of the following events within 30 minutes from the start of the intubation procedure and to describe the types of major adverse peri-intubation events: severe hypoxemia defined as an oxygen saturation as measured by pulse-oximetry <80%; hemodynamic instability defined as a SBP 65 mmHg recoded at least once or SBP < 90 mmHg for 30 minutes, a new requirement or increase of vasopressors, fluid bolus >15 mL/kg to maintain the target blood pressure; cardiac arrest. RESULTS: Among 142 patients, 73.94% experienced at least one major adverse peri-intubation event. The predominant event was cardiovascular instability, observed in 65.49% of all patients undergoing emergency intubation, followed by severe hypoxemia (43.54%). 2.82% of the patients had a cardiac arrest. CONCLUSION: In this study of intubation practices in critically ill patients with COVID-19, major adverse peri-intubation events were frequent. CLINICAL TRIAL REGISTRATION: www.
