Role of physical therapists in the weaning and extubation procedures of pediatric and neonatal intensive care units: a survey.

BACKGROUND: Weaning a patient from mechanical ventilation is a complex procedure that involves clinical and contextual aspects. Mechanical ventilation also depends on the characteristics of health professionals who work in intensive care.

OBJECTIVE: This study described the organizational aspects associated with the physical therapist's performance in the weaning procedure from mechanical ventilation and extubation in neonatal, pediatric and mixed (neonatal and pediatric) intensive care units in Brazil.

METHODS: In order to identify the existing intensive care units in Brazil, data from the National Health Facilities Census was used to enable the researchers to obtain information about registered units. A cross-sectional survey was carried out by sending an electronic questionnaire to 298 neonatal, pediatric and mixed intensive care units in Brazil.

RESULTS: This study assessed questionnaires from 146 intensive care units (49.3% neonatal, 35.6% pediatric and 15.1% mixed). A total of 57.5% of these units applied mechanical ventilation weaning protocols, and a physical therapist frequently conducted this procedure (66.7%). However, the clinician responsible for conducting the weaning and deciding when to do extubation varied regardless of ICU patient age profile. Regardless of the type of hospital or the type of units, most of these had a dedicated physical therapist. However, physical therapy care 24h/7 days per week was predominantly in pediatric intensive care units (56.0%), and in public hospitals (45.9%). Moreover, when the physical therapist was available 24h/7 days per week, (s)he was responsible for the mechanical ventilation extubation decision and patients were successfully extubated on the first attempt.

CONCLUSION: In this survey, intensive care units using physical therapy assistance 24h/7 days per week were associated with the use of a mechanical ventilation weaning protocol, an extubation decision and success commonly on the first attempt of extubation.
