ECHOVAP

Details and patient eligibility

About

Diagnosis of pneumonia remains difficult in intensive care unit (ICU), notably after cardiac surgery. Lung ultrasonography (LUS) has been successfully used for diagnosis of pneumonia, but its usefulness and reliability was never evaluated after cardiac surgery. This study investigates the clinical relevance of LUS for pneumonia diagnoses in cardiac ICU.

Enrollment: 51 patients

Sex: All

Ages: 18 to 99 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Cardiac surgery with sternotomy and cardio-pulmonary bypass (CPB) less than 3 days before

• At least one component suggestive of ARF:

  • If mechanical ventilation, a PaO2 / FiO2 ratio <200, or failure of weaning (failure of spontaneous ventilation test, re-intubation in the first 24 hours), or need for non-invasive ventilation immediately after extubation,
  • If spontaneous ventilation: clinical signs of acute respiratory distress (dyspnea at least exertion, cyanosis, polypnea> 25/min, upper or intercostal swallowing, abdominal swing ...), SpO2 < 90% or PaO2 <60 mmHg despite oxygen therapy ≥ 3L/min.

Exclusion criteria

• Minor patients
• Pregnancy
• Sleep apnea syndrome
• Participation refusal

Post operative respiratory failure

Description:

Patients with acute respiratory failure (ARF) less than 72 hours after a major cardiac surgery with cardiopulmonary bypass ARF was defined as one of the following conditions: * If mechanical ventilation, a partial pressure of oxygen/ inspired oxygen fraction ratio (PaO2/FiO2) \< 200, or failure of weaning (failure of spontaneous ventilation test, re-intubation in the first 24 hours), or need for non-invasive ventilation immediately after extubation, * If spontaneous ventilation: clinical signs of acute respiratory distress (dyspnea at least exertion, cyanosis, polypnea\> 25/min, upper or intercostal swallowing, abdominal swing ...), pulse oximetry (SpO2) \< 90% or PaO2 \<60 mmHg despite oxygen therapy ≥ 3 L/min.

Diagnostic Test: Lung Ultrasound
