E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
-18 years of age or older
-Clinical evidence of CPPE; defined as a neutrophilic exudated in the context of
a community acquired pneumonia; or empyema, defined as the presence of pus
in pleural cavity. A CPPE required, according to the attending physician, a chest
tube drainage. Most patients will satisfy the following criteria: 1) pleural fluid
pH < 7.2 or pleural fluid glucose < 60 mg/dL, 2) Gram-positive or pleural fluid
positive culture or 3) pleural effusion that occupy 50% or more of a hemithorax
in a thorax radiography or it is loculated in an image exploration (radiography,
ultrasound or computed tomography).
-Clinical stability 2 weeks after diagnosis and antibiotic therapy beginning,
defined as: 1) absence of fever (temperature < 37.8oC), heart rate < 100 bpm,
breath rate < 24 bpm and systolic blood pressure > 90 mmHg. 2) Thorax
radiography without pleural effusion or that occupy less than 20% of the
hemithorax without chest tube in that moment. 3) Serum C-reactive protein drop
of at least 50% from the diagnosis.
-Capable of giving written informed consent.
3. Clinical stability at 2 weeks of diagnosis and treatment with amoxicillin-clavulanate of DPPC or empyema. This must meet three requirements: 1) in the past 48 hours: T ª <37.8 ° C, HR <100 bpm FR <24 rpm and SBP> 90 mmHg, 2) pleural effusion on chest radiograph occupying less than 20% of the hemithorax with pleural drainage and retired at the time, and 3) decrease in serum C-reactive protein of at least 50% from diagnosis. |
1. Pacientes mayores de 18 años
2.Evidencia clínica de DPP, definido como un exudado
polimorfonuclear en el contexto de una neumonía comunitaria.
Empiema es la presencia de pus en la cavidad pleural. El DPPC
se define como aquel líquido no purulento que requiere, a criterio
del clínico, la inserción de un drenaje pleural. La mayoría de estos
pacientes cumplirán alguno de los siguientes criterios: 1) pH del
líquido pleural < 7.2 o glucosa < 60 mg/dL, 2) Gram o cultivo positivo
del líquido pleural, o 3) derrame pleural que ocupa el 50% o más
del hemitórax en la radiografía de tórax, o que está loculado en una
prueba de imagen (Rx, ecografía o TC).
3. Estabilidad clínica a las 2 semanas del diagnóstico y tratamiento
con amoxicilina-clavulánico del DPPC o empiema. Para ello se deben cumplir
tres requisitos: 1) en las últimas 48 horas: Ta <37,8oC, FC <100 lpm, FR<24
rpm y TAS>90 mmHg, 2) derrame pleural en la radiografía de tórax que
ocupe menos del 20% del hemitórax con el drenaje pleural ya retirado en ese
momento, y 3) descenso de la proteína C reactiva sérica de al menos el 50%
desde el diagnóstico. |
