简要总结
The purpose of this study is to evaluate the impact of an optimized suctioning procedure on the risk of endotracheal microaspiration, measured by tracheal to oropharyngeal ratio of amylase enzymatic activity.
详细描述
• Study design : This is an open prospective, cross-over cohort study, including patients ventilated in one medical intensive care unit. Two procedures will be compared in two distinct, randomly decided cross-over consecutive periods
• Detailed description : Standard cares include tracheal suctions several times a day. They can induce a cough reflex in non paralysed patients leading to the mobilisation of the endotracheal tube and a consecutive raise in the risk of tracheal microaspiration. Thus drainage of subglottic secretion before tracheal suction is expected to reduce microaspiration. Subglottic secretion drainage could decrease the risk of Ventilator Associated Pneumonia even if it remains to be confirmed. However, no study assessed its efficiency in reducing tracheal microaspiration.
An optimization of the oropharyngeal suction procedure will include the use of a subglottic drainage in a specified order to realize a so called "optimized oral care". A comparison will be done with a routine oral care.
We will conduct a crossover study in which the patient's follow-up will last 2 days. Length of suction procedure and mouth care, volume of oral, subglottic and tracheal secretions and their qualitative appearance will be collected. The amylase enzymatic activity will be assessed in oropharyngeal, subglottic and tracheal samples.
• Registry procedure : All requested information will be recorded on case report forms and explanation will be reported for any missing data. False data will be clearly corrected, and signed by investigator or authorised person. For biochemical data (amylase enzymatic activity), results will be transmitted through excel software via a key and data will be integrated to the principal excel file on professional computer of the investigator.

研究组 & 干预措施
Optimized oral care
An optimization of the oropharyngeal suction procedure will include use of a subglottic drainage in a specified order: 1. subglottic suction, 1.oral suction followed by mouth care 3. subglottic suction 4. tracheal suction
干预措施: Optimized oral care (Procedure)
Routine oral care
Oral suction followed by mouth care and tracheal suction
干预措施: Routine oral care (Other)
结局指标
主要结局
tracheal to oropharyngeal ratio of amylase enzymatic activity
时间窗: Day 1 and Day 2
As a surrogate for microaspiration, the tracheal to oropharyngeal ratio of amylase enzymatic activity will be assessed after oral care. A mean of measures realized one day after optimized oral care will be compared to a mean of measure realized the other day after standard oral care as a cross over protocol.
次要结局
- volume of the tracheal, subglottic, and oral suctions(three time a day, during 2 days)
- length of each mouth care(three time a day, during 2 days)
- cost of the optimized oral suctioning compared with routine care(At the end of the period of study (48hours) for each patient)
