Ventilatory Effect of Intensive Physiotherapy on Guillain-Barré Syndrome under Mechanical Ventilation

Abstract

Objective: To identify the effect of intensive physiotherapy on the ventilatory evolution of patients with syndrome of Guillain-Barré under mechanical ventilation. Material and Methods: This was a correlational and cross-sectional study with five patients, intubated, presenting with Guillain-Barré syndrome (n = 5) assisted with pressure- controlled mechanical ventilation. This study was based on the quantification of ventilatory, hemodynamic and gasometric parameters, carried out in two phases, before and after physiotherapeutic intervention. Data were analyzed using descriptive statistics and Student’s t-tests, with significance level of 0.05. Results: Hemodinamyc findings demonstrated stability of the patients before and after intervention, with MBP (96.7 ± 4.9 and 95.6 ± 3.4 mmHg); HR (109.9 ± 5.2 and 112.0 ± 4.4, bpm); RR (17.2 ± 1.6 and 15.9 ± 1.3 irpm); Tidal Volume (476.6 ± 10.4 and 485.4 ± 3.6 mL/Kg) controlled pressure (21.8 ± 0.7 and 22.2 ± 0.8 cmH2O); PEEP (6.8 ± 0.3 and 7.3 ± 0.2 cmH2O); pH (7.35 ± 0.08 and 7.47 ± 0.02); pCO2 (30.98 ± 3.95 and 30.96 ± 3.44); HCO-3 (25.51 ± 4.61 and 23.88 ± 1.85); pO2 (117.08 ± 13.15 and 129.28 ± 25.14); SaO2 (97.81 ± 0.27 and 97.46 ± 0.56); pO2/FiO2 (419.80 ± 76.70 and 520.60 ± 147.80). Conclusion: The results indicate satisfactory effects of physiotherapy according to the hemodinamic control and ventilatory action. However, it is recognized the severity of the disease under intensive care, what brings about the need for increasing the sample. DESCRIPTORS Guillain-Barre Syndrome. Ventilation, Mechanical.
