Purpose. To assess the potential effectiveness or efficacy of early mobilization on respiratory and peripheral muscle strengths and functionality in nonintubated patients. Methods. For 40 nonintubated patients over 18 years of age with over 24-hour intensive care unit (ICU) stay allocated to a single intervention, an incremental mobilization protocol was initiated. Maximal inspiratory and expiratory pressures (MIP and MEP), peripheral muscle strength (handgrip strength (HGS) and Medical Research Council scale (MRC-s)), and functionality (FIM, ICF-BMS, PFIT-s, and FSS-ICU scales) were evaluated at ICU admission and discharge. Results. All outcomes were significantly improved (pre vs. post values): MIP (43.93 ± 21.95 vs. 54.12 ± 21.68 cmH2O; P<0.001), MEP (50.32 ± 28.65 vs. 60.30 ± 21.23; P=0.002), HGS (25.5 (9.58) vs. 27.5 (9.48); P=0.046), MRC-s (58.52 ± 2.84 vs. 59.47 ± 1.81; P=0.023), FIM (54.4 ± 22.79 vs. 69.48 ± 12.74), ICF-BMS (28.63 ± 16.19 vs. 14.03 ± 11.15), PFIT-s (9.55 ± 2.34 vs. 11.18 ± 1.32) (P<0.001), and FSS-ICU (28.7 ± 9.1 vs. 32.6 ± 5.0; P=0.001). The ceiling effect at admission/discharge was in MRC-s (60/82.5%), FSS-ICU (50/70%), and FIM (35/62.5%). The floor effect occurred at discharge in ICF-BMS (7.5/52.5%). Conclusions. The early mobilization protocol seemed effective at maintaining/increasing the respiratory muscle strength and functionality of nonintubated patients in critical care. Ceiling effect was high for MRC-s, FSS-ICU, and FIM scales.
Introduction: Mobilization is an effective therapy to combat the deleterious effects of immobility, but not all patients are in a condition to be moved; thus, knowledge about contraindication criteria is fundamental. Objective: To evaluate the knowledge of physiotherapists working in adult ICUs on contraindications to the mobilization of critical patients. Method: This was a cross-sectional study in which a survey was applied to physiotherapists working in an adult ICU in the city of Recife. Results: Out of the 36 criteria presented, only five were considered contraindication criteria. Clinical parameters were those that obtained higher frequency for not being considered criteria for contraindication, nor were there observed differences in the relation between the time of working in the ICU. Conclusion: Most physiotherapists did not consider the criteria presented as contraindications to mobilization, so that professional training in mobilization practices and the creation of protocols are necessary.
Introduction and aim: Studies regarding asynchrony in patients in the cardiac postoperative period are still only a few. The main objective of our study was to compare asynchronies incidence and its index (AI) in 3 different modes of ventilation (volume-controlled ventilation [VCV], pressure-controlled ventilation [PCV] and pressure-support ventilation [PSV]) after ICU admission for postoperative care. Methods: A prospective parallel randomised trial in the setting of a non-profitable hospital in Brazil. The participants were patients scheduled for cardiac surgery. Patients were randomly allocated to VCV or PCV modes of ventilation and later both groups were transitioned to PSV mode. Results: All data were recorded for 5 minutes in each of the three different phases: T1) in assisted breath, T2) initial spontaneous breath and T3) final spontaneous breath, a marking point prior to extubation. Asynchronies were detected and counted by visual inspection method by two independent investigators. Reliability, inter-rater agreement of asynchronies, asynchronies incidence, total and specific asynchrony indexes (AIt and AIspecific) and odds of AI ≥10% weighted by total asynchrony were analysed. A total of 17 patients randomly allocated to the VCV (n= 9) or PCV (n=8) group completed the study. High inter-rated agreement for AIt (ICC 0.978; IC95%, 0,963-0.987) and good reliability (r=0.945; p<0.001) were found. Eighty-two % of patients presented asynchronies, although only 7% of their total breathing cycles were asynchronous. Early cycling and double triggering had the highest rates of asynchrony with no difference between groups. The highest odds of AI ≥10% were observed in VCV regardless the phase: OR 2.79 (1.36-5.73) in T1 vs T2, p=0.005; OR 2.61 (1.27-5.37) in T1 vs T3, p=0.009 and OR 4.99 (2.37-10.37) in T2 vs T3, p<0.001. Conclusions: There was a high incidence of breathing asynchrony in postoperative cardiac patients, especially when initially ventilated in VCV. VCV group had a higher chance of AI ≥10% and this chance remained high in the following PSV phases.
