Brief Summary
Conventional catheter suctioning of respiratory tract secretions is a mandatory procedure in intubated patients. Poor tolerance, pain and other, sometimes severe, lung and cardiovascular complications may occur during suctioning. Mechanical insufflation-exsufflation (MIE), coupled with hypertonic saline (HS), may improve efficacy airway clearance and reduce risk of the maneuver. However, safety of MIE and HS in intubated patients have not been studied appropriately, which justifies a randomized evaluation compared to conventional secretion suctioning.

Outcome Measures
Primary Outcomes (4)
Aggregate cardiovascular and respiratory adverse events of mechanical insufflation-exsufflation and hypertonic saline.
Comparative incidence of aggregate hemodynamic and respiratory adverse events. Adverse events criteria are predefined and will be expressed as: * Percentage of patients meeting aggregate predefined hemodynamic or respiratory adverse event criteria per study group. * Percentage of specific predefined adverse events (outcome variable "yes" or "no"): Desaturation (pulse-oximetry, \>5%), hemoptisis (yes or no), bronchospasm (needing bronchodilator therapy), pneumothorax (as assessed by chest X-ray), hypotension (\>30% or \>10% increase in noradrenaline infusion from baseline), hypertension (\>30% or \>10% decrease in noradrenaline infusion from baseline), tachycardia (\>90 bpm or \>30% increase), bradycardia (\<40 bpm), arrythmias (supra ventricular, requiring therapy), atelectasis (as assessed by chest X-ray), and other complications occuring during or within 1 hour after the procedure.
1 hour
Pain score during mechanical insufflation-exsufflation and hypertonic saline as assessed by quantitative a pain scoring systems.
Comparative pain scores of the study procedures in the 4 study groups will be assessed using the "ESCID" pain score (EScala de Conductas Indicadoras de Dolor, ranging from 0, no pain, to \>6, intense pain, see citations) at baseline, during the procedure and at 5 and 60 minutes after the aspiration of respiratory secretions. Both comparison of the score at the 4 study time-points and their variations between time-points will be analysed.
1 hour
Sedation/agitation score during mechanical insufflation-exsufflation and hypertonic saline as assessed by a quantitative sedation/agitation system.
Comparative sedation/agitation score of the study procedures in the 4 study groups will be assessed using the RASS (Richmond Agitation-Sedation Scale, see citations), range -5, un-arousable, to +5, combative) at baseline, during the procedure and at 5 and 60 minutes after the aspiration of respiratory secretions.
1 hour
Sedation/responsiveness score during mechanical insufflation-exsufflation and hypertonic saline as assessed by quantitative a sedation scoring system.
Comparative sedation/responsiveness score of the study procedures in the 4 study groups will be assessed using the responsiveness "Ramsay" Sedation Scale, range from 1, anxious and agitated, to 6, no response to stimulus, see citations) at baseline, during the procedure and at 5 and 60 minutes after the aspiration of respiratory secretions.
