Meta Analysis Comparative Study[The effects and safety of closed versus open tracheal suction system: a meta analysis].
To evaluate the effects and safety of closed tracheal suction system(CTSS) versus open tracheal suction system (OTSS) for mechanically ventilated patients. ⋯ Compared with OTSS, CTSS could reduce disturbance to respiratory and circulatory system by sputum suction and shorten the duration of mechanical ventilation. However, CTSS has no advantage in prevention of ventilator associated pneumonia or microbial colonization, nor does it shorten the length of ICU stay or improve the outcome of mechanically ventilated patients.
