RESUMO

Rationale: Acute hypoxemic respiratory failure is a condition that comprises a wide array of entities. Obtaining a histological lung sample might help reach a diagnosis and direct an appropriate treatment in a select group of patients. Objective: To describe our experience in the use of cryobiopsy for the diagnosis of acute hypoxemic respiratory failure of undetermined origin. Methods: Retrospective analysis of case series of patients with acute hypoxemic respiratory failure who underwent lung cryobiopsy at the Intensive Care Unit of the Hospital Italiano de Buenos Aires, Argentina. Results: Cryobiopsy yielded a histological diagnosis in all patients (n = 10, 100%). This led to either a change in therapy or continuation of a specific treatment in eight of these patients. Cryobiopsy was found to be contributive in all the patients who did not meet Berlin criteria for acute respiratory distress syndrome. No major complications were associated with the procedure. Conclusions: Cryobiopsy is a safe procedure with a high diagnostic yield in a selected group of patients.

RESUMO

RESUMEN: Introducción: El síndrome de Takotsubo (ST) es una miocardiopatía reversible que tiene diversas formas de presentación. Hasta el momento no se han publicado datos de ST en nuestro medio. Material y Métodos: Desde el 2005 al 2017 se incluyeron a 115 pacientes con diagnóstico de ST primario o secundario en el Hospital Italiano de Buenos Aires. El objetivo fue evaluar las características clínicas del ST durante la internación. Resultados: La mediana de edad de la población fue de 78 años (64-84), el 90% eran mujeres, y el 22% presentó enfermedad coronaria asociada. El 57% eran ST primarios, 31% tuvieron un gatillo emocional y 44%, físico. El síndrome de presentación fue como shock: 9%, insuficiencia cardiaca 12%, "tipo SCA" 70%, ACV/embolia 5% y, arritmias, 4%. La mediana de Fey al ingreso fue del 40% (36-50) y su recuperación, desde el ingreso al alta (mediana de internación de 4 días, 3-8), fue del 20%, p < 0.001. La mortalidad hospitalaria fue de 4/115 (3,48%). En el análisis univariado, las variables asociadas a mayor mortalidad fueron: shock respecto a otras formas de presentación (p = 0.0035) y ST secundario respecto al primario, p = 0.020. Además, existió una relación directa entre la mortalidad y los niveles de NT-pro-BNP máximo (p = 0.0082) y glóbulos blancos (p = 0.0101). Asimismo, la mortalidad hospitalaria mostró una relación inversa con el hematocrito (p = 0.0084) y con las alteraciones en el ECG de ingreso; es decir, que los pacientes que fallecieron durante la internación tuvieron ECG normal al ingreso con mayor frecuencia (p < 0.001). Conclusión: En este registro unicéntrico se observó que los pacientes tuvieron más comorbilidades y similar mortalidad respecto a registros internacionales.


ABSTRACT: Background: Takotsubo syndrome (TS) is a reversible cardiomyopathy with many different forms of presentations. There is no local data of TS published so far. Methods: One hundred and fifteen patients with either primary or secondary TS were retrospectively studied at Hospital Italiano de Buenos Aires from 2005 to 2017. The purpose of the study was to assess the clinical features of this population during hospitalization. Results: Median of age was 78 years (64-84); 90% of patients were female, and 22% had associated coronary artery disease. Fifty-seven percent of cases were primary TS, 31% experienced an emotional trigger and 44% had a physical origin. The presentation syndrome was as follows: 9% shock, 12% heart failure, 70 % mimicking acute coronary syndrome, 5% stroke/peripheral embolism and 4% arrhythmias. Median ejection fraction at admission was 40% (36-50) and recovery from admission to discharge [median hospital stay: 4 days (3-8)] was 20%, p <0.001. In-hospital mortality was 4/115 cases (3.48%). In univariate analysis, shock compared with other forms of presentation (p=0.0035) and secondary TS (p=0.020) were associated with higher in-hospital mortality. There was a direct relationship between in-hospital mortality and maximum NT-pro-BNP levels (p= 0.0082) and white cell count (p=0.0101). In addition, in-hospital mortality was inversely associated with hematocrit (p=0.0084) and with ECG abnormalities at admission; i.e. patients who died during hospitalization had more frequently normal ECG at admission, (p<0.001). Conclusion: Compared with international registries, this single center population had more comorbidities, but similar in-hospital mortality rates.

RESUMO

RESUMEN Objetivo: El desarrollo de la membrana de oxigenación extracorpórea en América Latina representa un desafío para la especialidad. El objetivo de este artículo fue describir los resultados de un nuevo programa de membrana de oxigenación extracorpórea en una unidad de cuidados intensivos. Métodos: Estudio de cohorte retrospectivo. Incluye 22 pacientes que requirieron membrana de oxigenación extracorpórea desde Enero de 2011 hasta Junio de 2014. Se evaluaron características basales, indicaciones, duración de la corrida, días de ventilación mecánica, días de unidad de cuidados intensivos, complicaciones y mortalidad hospitalaria. Resultados: Quince pacientes requirieron membrana de oxigenación extracorpórea post-trasplante pulmonar y 7 pacientes por distrés respiratorio agudo. Todos los pacientes trasplantados fueron destetados de membrana de oxigenación extracorpórea, con una duración mediana de 3 días (Rango intercuantil - IQR: 2 - 5), de ventilación mecánica 15,5 días (IQR: 3 - 35), de estadía unidad de cuidados intensivos 31,5 días (IQR: 19 - 53) y de estadía hospitalaria 60 días (IQR: 36 - 89), con una mortalidad de 20%. Los pacientes con distrés respiratorio agudo tuvieron una mediana de duración de membrana de oxigenación extracorpórea de 9 días (IQR: 3 - 14), mediana de ventilación mecánica 25 días (IQR: 13 - 37), de estadía en terapia 31 días (IQR: 11 - 38), y hospitalaria 32 días (IQR: 11 - 41), y 57% de mortalidad. Las principales complicaciones fueron infecciones (80%), insuficiencia renal aguda (43%), sangrados en sitio quirúrgico y de inserción de cánulas (22%), plaquetopenia (60%) y coagulopatía (30%). Conclusión: A pesar de encontrarnos transitando una curva de aprendizaje, consideramos la experiencia satisfactoria, con resultados y complicaciones comparables a las reportadas en la literatura. .


ABSTRACT Objective: The development of the extracorporeal membrane oxygenation in Latin America represents a challenge in this specialty field. The objective of this article was to describe the results of a new extracorporeal membrane oxygenation program in an intensive care unit. Methods: This retrospective cohort study included 22 patients who required extracorporeal membrane oxygenation and were treated from January 2011 to June 2014. The baseline characteristics, indications, duration of the condition, days on mechanical ventilation, days in the intensive care unit, complications, and hospital mortality were evaluated. Results: Fifteen patients required extracorporeal membrane oxygenation after lung transplantation, and seven patients required oxygenation due to acute respiratory distress. All transplanted patients were weaned from extracorporeal membrane oxygenation with a median duration of 3 days (Interquartile range - IQR: 2 - 5), were on mechanical ventilation for a median of 15.5 days (IQR: 3 - 25), and had an intensive care unit stay of 31.5 days (IQR: 19 - 53) and a median hospital stay of 60 days (IQR: 36 - 89) with 20% mortality. Patients with acute respiratory distress had a median oxygenation membrane duration of 9 days (IQR: 3 - 14), median mechanical ventilation time of 25 days (IQR: 13 - 37), a 31 day stay in therapy (IQR: 11 - 38), a 32 day stay in the hospital (IQR: 11 - 41), and 57% mortality. The main complications were infections (80%), acute kidney failure (43%), bleeding at the surgical site and at the site of cannula placement (22%), plateletopenia (60%), and coagulopathy (30%). Conclusion: In spite of the steep learning curve, we considered this experience to be satisfactory, with results and complications comparable to those reported in the literature. .

RESUMO

The aim of this study was to determine typical values for non-invasive volumetric capnography (VCap) parameters for healthy volunteers and anesthetized individuals. VCap was obtained by a capnograph connected to the airway opening. We prospectively studied 33 healthy volunteers 32 ± 6 years of age weighing 70 ± 13 kg at a height of 171 ± 11 cm in the supine position. Data from these volunteers were compared with a cohort of similar healthy anesthetized patients ventilated with the following settings: tidal volume (VT) of 6-8 mL/kg, respiratory rate 10-15 bpm, PEEP of 5-6 cmH2O and FiO2 of 0.5. Volunteers showed better clearance of CO2 compared to anesthetized patients as indicated by (median and interquartile range): (1) an increased elimination of CO2 per mL of VT of 0.028 (0.005) in volunteers versus 0.023 (0.003) in anesthetized patients, p < 0.05; (2) a lower normalized slope of phase III of 0.26 (0.17) in volunteers versus 0.39 (0.38) in anesthetized patients, p < 0.05; and (3) a lower Bohr dead space ratio of 0.23 (0.05) in volunteers versus 0.28 (0.05) in anesthetized patients, p < 0.05. This study presents reference values for non-invasive volumetric capnography-derived parameters in healthy individuals. Mechanical ventilation and anesthesia altered these values significantly.
