Abstract

Background

Tracheal suctioning costs are higher with a closed tracheal suction system (CTSS) than with an open system (OTSS), due to the need for complete daily change as recommended by the manufacturer. However, is it necessary to change the closed system daily?

Objective

To evaluate the tracheal suctioning costs and incidence of ventilator-associated pneumonia (VAP) using closed system without daily change vs OTSS.

Design

Prospective and randomised study.

Setting

An Intensive Care Unit in a university hospital.

Patients

Patients requiring mechanical ventilation.

Interventions

Patients were randomly assigned to CTSS without daily change or OTSS. We used a CTSS that allowed partial or complete change.

Measurements and results

There were no significant differences between both groups of patients (236 with CTSS and 221 with OTSS) in gender, age, diagnosis, APACHE-II score, mortality, number of aspirations per day, percentage of patients who developed VAP (13.9 vs 14.1%) or the number of ventilator-associated pneumonia per 1000 days of mechanical ventilation (14.1 vs 14.6). There were not significant differences in tracheal suctioning costs per patient/day between CTSS vs OTSS (2.3 ± 3.7 vs 2.4 ± 0.5 Euros; p = 0.96); however, when length of mechanical ventilation was lower than 4 days, the cost was higher with CTSS than with OTSS (7.2 ± 4.7 vs 1.9 ± 0.6 Euros; p < 0.001); and when length of mechanical ventilation was higher than 4 days, the cost was lower with CTSS than with OTSS (1.6 ± 2.8 vs 2.5 ± 0.5 Euros; p < 0.001).

Conclusion

CTSS without daily change is the optimal option for patients needing tracheal suction longer than 4 days.
