Continuous Control of Tracheal Cuff Pressure and Microaspiration in Critically Ill Patients

2014-08-27 03:15:23 | BioPortfolio


We hypothesized that continuous control of tracheal cuff pressure would reduce microaspiration of gastric content as determined by pepsin level in tracheal aspirate.


Randomized controlled open label study, performed in a 10-bed ICU. All patients intubated with a PVC-cuffed tracheal tube and receiving enteral nutrition who require at least 48 h of mechanical ventilation are eligible. Patients receive continuous control of cuff pressure using a pneumatic device (intervention group) or manual control using a manometer (control group). Target cuff pressure is 25 cmH2O.

In all patients, pepsin is measured in tracheal aspirate during a 48-h period after inclusion, as proxy for gastric content aspiration. In addition tracheobronchial colonization and ventilator associated pneumonia rates will be compared between the two groups.

Instruments for measuring arterial blood pressure consisting of an inflatable cuff, inflating bulb, and a gauge showing the blood pressure. (Stedman, 26th ed)

Compression of the rotator cuff tendons and subacromial bursa between the humeral head and structures that make up the coracoacromial arch and the humeral tuberosities. This condition is associated with subacromial bursitis and rotator cuff (largely supraspinatus) and bicipital tendon inflammation, with or without degenerative changes in the tendon. Pain that is most severe when the arm is abducted in an arc between 40 and 120 degrees, sometimes associated with tears in the rotator cuff, is the chief symptom.

Injuries to the ROTATOR CUFF of the shoulder joint.

Rapidly destructive shoulder joint and bone disease found mainly in elderly, and predominantly in women. It is characterized by SHOULDER PAIN; JOINT INSTABILITY; and the presence of crystalline CALCIUM PHOSPHATES in the SYNOVIAL FLUID. It is associated with ROTATOR CUFF INJURIES.

The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).
