Study protocol
In the preoperative period, all
patients included in the survey underwent a 10-meter walk test. The
following day, everyone underwent a surgical procedure, was referred to
the Intensive Care Unit (ICU) and, being discharged, was directed to the
inpatient unit. In all these moments, they received routine care from
the unit without any influence from the researchers. All patients were
assisted by the physiotherapist on duty and performed breathing
exercises, orthostasis training on the first postoperative day, sitting
in the chair and ambulation on the second postoperative day when there
was no clinical contraindication (use of vasoactive drugs, uncontrolled
pain or infectious changes). On the day of hospital discharge, patients
repeated the 10-meter test.
After the repetition of the gait speed test, patients were divided into
two groups: slow and non-slow. The cutoff point used was 1.0 m / s based
on the study by Odonkor et al.10 Those who were not
discharged walked less than 1.0 m / s occupied the slow group and those
who were above 1.0 m / s were classified as not slow. Patients were
followed for six months to observe the primary outcome, which was the
need for hospital readmission. There was a comparison between the groups
of the initial, final butch speed, delta velocity, cardiopulmonary
bypass (CPB), mechanical ventilation (MV), Intensive Care Unit (ICU)
time and hospital stay. It is worth mentioning that readmission in any
hospital was counted for this study, patients were contacted by
telephone seeking this type of information.
