RESUMO
Since 1970, prone decubitus (PD) has been used as adjuvant therapy to treat severe hypoxia in patients with acute respiratory distress syndrome (ARDS), and now with the COVID-19 pandemic, its use has become widespread in ICUs. ARDS is characterized by diffuse bilateral radiographic infiltrates, decreased respiratory compliance, small lung volumes, and severe hypoxemia. The placement of vascular access in PD seems to be feasible and safe, since, as has been described, the number of complications such as pneumothorax, bleeding, and arterial punctures are almost nil, especially when performed under ultrasound guidance. The patients who could benefit most from this procedure seem to be those with obesity, mainly with a body mass index greater than 30 kg/m2, in whom the return to the supine position may represent a risk of respiratory or hemodynamic deterioration.
RESUMO
Spontaneous lesions can affect only a part of the esophageal wall (Mallory-Weiss syndrome) or constitute a full-thickness rupture of the organ, leading to Boerhaave syndrome. Most commonly affecting males between 50 and 70 years of age, Clinically, the Mackler triad is vomiting, severe chest pain, and subcutaneous cervical emphysema. The delay in diagnosis explains the high mortality rate of this pathology up to 40-60% in those treated at 48 hours. The prognosis improves if treatment is established within the first 24 hours.
Las lesiones espontáneas pueden afectar solo una parte de la pared esofágica (síndrome de Mallory-Weiss) o constituir una rotura de espesor total del órgano, dando lugar al síndrome de Boerhaave. Afecta con mayor frecuencia a los varones entre 50 y 70 años de edad. Clínicamente conforma la tríada de Mackler: vómito, dolor torácico intenso y enfisema subcutáneo cervical. El retraso en el diagnóstico explica su alta tasa de mortalidad, de hasta el 40-60% en los pacientes tratados a las 48 horas. El pronóstico mejora si se logra instaurar el tratamiento dentro de las primeras 24 horas.
