Intraabdominal Hypertension and Occurrence of Microaspiration in Cirrhotics Under Mechanical Ventilation

Impact of Intraabdominal Hypertension on Microaspiration Incidence in Cirrhotic Patients

The study aims to demonstrate the relationship between intra-abdominal hypertension (IAH) and abundant microaspirations in mechanically ventilated cirrhotic.

Intra-abdominal pressure monitoring will be performed using intra-vesical pressure every 8 hour in the first 2 days of mechanical ventilation.

Micro aspiration is defined by pepsin or amylase positivity in trachea suction. Two groups will be compared : one with IAH , one without IAH.

Inclusion Criteria:

• adult patients
• Cirrhosis
• intubation and mechanical ventilation

Exclusion Criteria:

• pregnancy
• oliguric patients
• impossibility to measure intravesical pressure
