METHODS: A randomized controlled clinical trial was conducted with 59 male and female patients on mechanical ventilation. The patients were divided into a conventional physical therapy group (control group, n=14) that received the sector’s standard physical therapy program and an early mobilization group (n=14) that received a systematic early mobilization protocol. Peripheral muscle strength was assessed with the Medical Research Council score, and respiratory muscle strength (determined by the maximal inspiratory and expiratory pressures) was measured using a vacuum manometer with a unidirectional valve. Systematic early mobilization was performed on five levels. RESULTS: Significant increases were observed for values for maximal inspiratory pressure and the Medical Research Council score in the early mobilization group. However, no statistically significant improvement was observed for maximal expiratory pressure or MV duration (days), length of stay in the intensive care unit (days), and length of hospital stay (days). CONCLUSION: The early mobilization group showed gains in inspiratory and peripheral muscle strength.

Views0See moreINTRODUCTION: Tracheostomy is probably the most common surgical procedure in critically ill patients and is generally performed to facilitate mechanical ventilation weaning. Evidence-based guidelines have confirmed the benefits of tracheostomy weaning protocols and of the physiotherapists engagement in this process; however, no consensus decannulation criteria are currently available. Therefore, this study aimed to evaluate the influence of peripheral muscle strength and other indicators on decannulation success. METHODS: This was an observational retrospective study that analyzed the medical records of patients admitted to the medical and surgical intensive care unit of Hospital Agamenon Magalhães between March 2007 and August 2009. Respiratory and peripheral muscle strengths were evaluated in decannulated patients. RESULTS: Overall, 1,541 patients were evaluated, 143 of which had been tracheostomized, and only 57 of which had been decannulated. Forty-six patients had a satisfactory decannulation outcome, while 11 had decannulation failure, requiring the return to an artificial airway within 2 weeks. The calculated Medical Research Council peripheral muscle strength score was significantly lower for the failure group than for the successful decannulation group (28.33 ± 15.31 vs. 41.11 ± 11.52; P = 0.04). Scores above or equal 26 had 94.4% sensitivity and 50.0% specificity for the decannulation outcome, with an area under the ROC curve of 0.7593. In addition, white blood cell counts were higher in decannulation failure group patients (14,070 ± 3,073 vs. 10,520 ± 3,402 cells/μL; P = 0.00). CONCLUSION: This study has shown that peripheral muscle strength and blood leucocyte counts evaluated on the day of decannulation may influence the tracheostomy decannulation success rate.

Views0See moreOBJECTIVES: In mechanically ventilated patients, humidifier devices are used to heat and moisturize the inspired gas. Heating and humidifying inspired gas may prevent complications associated with the respiratory mucosa dryness such as mucus plugging and endotracheal tube occlusion. Two devices have been commonly used to this, either heated humidifier or the heat moisture exchange filter. This study aimed to compare the effects of the heated humidifier and a model of heat moisture exchange filter on respiratory mechanics in mechanically ventilated neurological patients. METHODS: This was a randomized crossover trial, involving 31 neurological patients under mechanical ventilation randomly assigned to the humidification devices. Expired tidal volume, peak inspiratory flow, peak expiratory flow, static compliance, dynamic compliance and respiratory system resistance were evaluated. Statistical analysis used the Kolmogorov-Smirnov test and Student’s t test for paired samples, in which P values < 0.05 were considered significant. RESULTS: The heat moisture exchanger filter decreased expired tidal volume, peak inspiratory flow, peak expiratory flow (p < 0.001) and dynamic compliance (p = 0.002), and increased respiratory system resistance (p < 0.001). CONCLUSION: In the studied population, the use of a heat moisture exchange filter model leaded to several changes on respiratory mechanics parameters.
