Comparing influence of intermittent subglottic secretions drainage with/without closed suction systems on the incidence of ventilator associated pneumonia.
Intermittent subglottic drainage (ISD) of secretions is recommended for prevention of ventilator-associated pneumonia (VAP) as it reduces microaspiration from the area around the cuff. Poor suction techniques can contribute to VAP, hence closed suction system (CSS) may have theoretical benefit in VAP prevention. Combination of these two techniques may provide added advantage. ⋯ ISD of secretions reduces the incidence of VAP. CSS alone or in combination with ISD has no significant effect on VAP incidence. Hence, ISD may be recommended for VAP prevention, but indications other than VAP prevention should determine the type of the suction system.
