Abstract

OBJECTIVE:

To compare the percentage of infants and children successfully extubated after a trial of breathing performed with either pressure support or T-piece.

DESIGN:

Prospective and randomized study.

SETTING:

Three medical-surgical pediatric intensive care units (PICUs).

PATIENTS:

Two hundred fifty-seven consecutive infants and children who received mechanical ventilation for at least 48 h and were deemed ready to undergo a breathing trial by their primary physician.

INTERVENTIONS:

Patients were randomly assigned to undergo a trial of breathing in one of two ways: pressure support of 10 cmH2O or T-piece. Bedside measurements of respiratory function were obtained immediately before discontinuation of mechanical ventilation and within the first 5 min of breathing through a T-piece. The primary physicians were unaware of those measurements, and the decision to extubate a patient at the end of the breathing trial was made by them.

MEASUREMENTS AND MAIN RESULTS:

Of the 125 patients in the pressure support group, 99 (79.2%) completed the breathing trial and were extubated, but 15 of them (15.1%) required reintubation within 48 h. Of the 132 patients in the T-piece group, 102 (77.5%) completed the breathing trial and were extubated, but 13 of them (12.7%) required reintubation within 48 h. The percentage of patients who remained extubated for 48 h after the breathing trial did not differ in the pressure support and T-piece groups (67.2% versus 67.4%, p=0.97).

CONCLUSIONS:

In infants and children mechanically ventilated, successful extubation was achieved equally effectively after a first breathing trial performed with pressure support of 10 cmH2O or a T-piece.
