ABSTRACT
Resumen Introducción : Hay información escasa sobre evolución a largo plazo de pacientes hospitalizados por neumo nía COVID-19 moderada (NM) y grave (NG). El objetivo del estudio fue determinar impacto clínico, funcional respiratorio y tomográfico (TACAR) luego del alta a 12 meses del diagnóstico. Métodos : análisis según grupos NM y NG, desatura dores (PD) en prueba de caminata 6 min (PC6M) y patrón tomográfico símil fibrótico (SF). Comparamos resultados a 3 y 12 meses de seguimiento. Resultados : 194 pacientes enrolados, evaluados al año: 103 (53% ): masculinos (62.4%), edad 57.7 ± 10.9 años, comorbilidades (hipertensión arterial 38.8%, dia betes 29.6%, antecedentes respiratorios-AR- 18.4%). Com paramos variables a los 3 y 12 meses (media/DE): CVF 84%(19) a 88(19) (p = 0.01); 27% tuvo CVF<80% al año. En PC6M: 426 metros (108) a 447(92) (p = < 0.01). El 12.8% fue PD al año. NG tuvo mayor SF (40% vs. 27.9% p = 0.021). SF se relacionó con CVF <80% (p = 0.004) en toda la co horte, y NG (p < 0.001). Al año en análisis multivariado se asoció a CVF <80%, AR (OR 4.32, 1.15-16.25), diabetes (OR 2.96, 1.02-8.57) y patrón SF (OR 3.51, 1.25-9.88). PD se asoció a AR (OR 12.2, 2.41-61.85). Discusión : Se observó mejoría en todas las variables al año. Pero al año persisten alteraciones funcionales y tomográficas en <50% de los pacientes. El subgrupo de PD se relacionó a AR. Es importante el seguimiento protocolizado de los pacientes hospitalizados, especial mente los grupos NG, PD y SF.
Abstract Introduction : There is scarce information on longterm evolution of hospitalized patients with moderate (MP) and severe (SP) COVID-19 pneumonia. Objective: to de termine clinical, respiratory function, and tomographic (HRCT) impact after being discharged 12 months after diagnosis. Methods : Analysis according to MP and SP, desatura tor patients (DP) in 6-minute walking test (6MWT) and HRCT fibrotic-like pattern (FLP). Results compared at 3 and 12 months of follow-up. Results : 194 patients enrolled and one year later 103 (53%) were evaluated: gender male (62.4%), age 57.7 ± 10.9 years, comorbidities (arterial hypertension 38.8%, diabetes 29.6%, and respiratory diseases-RD-18.4%). Variables compared 3 months to 12 months (mean/SD): FVC: 84%( 19) to 88%( 19) (p= 0.01). A 27% of patients had FVC<80% at one year. In 6MWT:426 (108) to 447 (92) (p = <0.01). 12.8% are DP in one year. SP had a greater FLP than MP (40% vs. 27.9%, p = 0.021). The FLP group was related to FVC < 80% (p = 0.004) in all patients but only in SP (p < 0.001). After one year, in multivariate analysis, FVC < 80% was associated with RD (OR 4.32, 1.15-16.25), diabetes (OR 2.96, 1.02-8.57) and FLP (OR 3.51, 1.25-9.88). DP were associated with RD (OR 12.2, 2.41-61.85). Discussion : Improvement was observed in all vari ables when comparing 3 to 12 months. However, after one year, functional and tomographic alterations persist in less than 50% of patients. DP subgroup was related to RD. Protocolled follow-up of hospitalized patients is important, especially in SP, DP, and FLP groups.

BACKGROUND: Two orotracheal extubation techniques are described in the literature: the traditional technique and the positive-pressure technique. Although prior studies reported better clinical outcomes with the positive-pressure extubation technique, its superiority has not been extensively studied yet. This study was to determine whether the positive-pressure orotracheal extubation technique, compared with the traditional orotracheal extubation technique, reduces the incidence of major postextubation complications (up to 60 min) in critically ill adult subjects. METHODS: This was a multi-center randomized clinical trial. Subjects age > 18 y, requiring invasive mechanical ventilation through an endotracheal tube, who met the orotracheal extubation criteria were included and randomized to traditional extubation group (removing the endotracheal tube by applying continuous endotracheal suctioning during the entire procedure) or positive-pressure group (application of pressure support mode at 15/10 cm H2O during cuff deflation and extubation). The primary measure was postextubation major complications, defined as the clinical evidence of at least one of the following: desaturation, upper-airway obstruction, or vomiting. RESULTS: A total of 725 subjects was randomly assigned to the traditional extubation group (n = 358) and positive-pressure group (n = 367). Seventeen subjects were eliminated and not included in the per-protocol analysis. Of 708 subjects, 185 (26.1%) developed at least one major complication. The incidence was 27.8% (96/345) in the traditional group compared with 24.5% (89/363) in the positive-pressure group. No statistically significant differences were observed between the 2 groups (absolute risk 3% [95 CI -3 to 10]; relative risk, 0.88 [95 CI 0.69-1.13], P = .32). CONCLUSIONS: Despite the trend toward the positive-pressure group, no statistically significant differences were observed. Our findings agree with the literature in that positive-pressure extubation is a safe procedure; therefore, both techniques may be used during extubation in critically ill adult patients.

OBJECTIVE: To describe the usual practice of mobility therapy in the adult intensive care unit for patients with and without COVID-19. METHODS: Online survey in which physical therapists working in an adult intensive care unit in Argentina participated. Sixteen multiple-choice or single-response questions grouped into three sections were asked. The first section addressed personal, professional and work environment data. The second section presented questions regarding usual care, and the third focused on practices under COVID-19 pandemic conditions. RESULTS: Of 351 physical therapists, 76.1% answer that they were exclusively responsible for patient mobility. The highest motor-based goal varied according to four patient scenarios: Mechanically ventilated patients, patients weaned from mechanical ventilation, patients who had never required mechanical ventilation, and patients with COVID-19 under mechanical ventilation. In the first and last scenarios, the highest goal was to optimize muscle strength, while for the other two, it was to perform activities of daily living. Finally, the greatest limitation in working with patients with COVID-19 was respiratory and/or contact isolation. CONCLUSION: Physical therapists in Argentina reported being responsible for the mobility of patients in the intensive care unit. The highest motor-based therapeutic goals for four classic scenarios in the closed area were limited by the need for mechanical ventilation. The greatest limitation when mobilizing patients with COVID-19 was respiratory and contact isolation.
OBJETIVO: Describir la práctica habitual de asistencia kinésica motora en la unidad de cuidados intensivos de adultos, tanto en pacientes con y sin COVID-19. MÉTODOS: Estudio observacional transversal de tipo encuesta online. Se incluyeron kinesiólogos que trabajan en unidades de cuidados intensivos de adultos en Argentina. Se realizaron 16 preguntas de respuesta múltiple o simple agrupadas en 3 apartados. El primero caracterizado por datos personales, profesionales o del ámbito laboral. El segundo, destinado a conocer el accionar habitual y un tercero enfocado en las prácticas bajo la pandemia COVID-19. RESULTADOS: Sobre 351 kinesiólogos, el 76.1% reportó que la movilización de los pacientes estaba a cargo exclusivamente de ellos. El objetivo máximo a alcanzar desde el aspecto motor fue variable según cuatro escenarios: Pacientes en ventilación mecánica, desvinculados de la ventilación mecánica, los que nunca estuvieron asociados a la ventilación mecánica y con COVID-19 en ventilación mecánica. En el primer y último escenario el objetivo máximo fue optimizar valores de fuerza muscular. En los restantes fue realizar actividades de la vida diaria. Por último, la mayor limitante en el abordaje de pacientes con COVID-19 fue el aislamiento respiratorio y/o de contacto. CONCLUSIÓN: Los kinesiólogos en Argentina reportaron encargarse de la movilización de los pacientes en la unidad de cuidados intensivos. Los objetivos máximos desde el aspecto motor para cuatro escenarios clásicos en el área cerrada podrían estar determinado por la asociación con la ventilación mecánica. La mayor limitación a la hora de movilizar a pacientes con COVID-19 fue el aislamiento respiratorio y de contacto.

BACKGROUND: Laboratory studies suggest applying positive pressure without endotracheal suction during cuff deflation and extubation. Although some studies reported better physiological outcomes (e.g. arterial blood gases) with this technique, the safety of positive pressure extubation technique has not been well studied. The aim of this study was to determine the safety of the positive-pressure extubation technique compared with the traditional extubation technique in terms of incidence of complications. METHODS: Adult subjects who were critically ill and on invasive mechanical ventilation who met extubation criteria were included. The subjects were randomly assigned to positive-pressure extubation (n = 120) or to traditional extubation (n = 120). Sequential tests for noninferiority and, when appropriate, for superiority were performed. Positive pressure was considered noninferior if the upper limit of the CI for the absolute risk difference did not exceed a threshold of 15% in favor of the traditional group, both in per protocol and intention-to-treat analyses. A P value of <.05 was considered significant. RESULTS: A total of 236 subjects were included in the primary analysis (per protocol) (119 in the positive-pressure group and 117 in the traditional group). The incidence of overall major and minor complications, pneumonia, extubation failure, and reintubation was lower in the positive-pressure group than in the traditional group, with statistical significance for noninferiority both in the per protocol (P < .001) and intention-to-treat (P < .001) analyses. The lower incidence of major complications found in the positive-pressure group reached statistical significance for the superiority comparison, both in per protocol (P = .03) and intention-to-treat (P = .049) analyses. No statistically significant differences were found in the superiority comparison for overall complications, minor complications, pneumonia, extubation failure, and reintubation. CONCLUSIONS: Positive pressure was safe and noninferior to traditional extubation methods. Furthermore, positive pressure has shown to be superior in terms of a lower incidence of major complications. (ClinicalTrials.gov registration NCT03174509.).
