RESUMO
BACKGROUND: The aim of this study was to evaluate the effects of integrated thermal rehabilitation care (ITRC) on postural balance and health-related quality of life in subjects with basic autonomy. MATERIALS AND METHODS: From June to December 2021, a total of 50 individuals with six points on the Katz Index of Independence in Activities of Daily Living (ADL) and a mean age of 66 (DS ± 12), comprising 27 (54%) males and 23 (46%) females, were selected. This study was carried out at the Thermal Medical Center of Castelnuovo della Daunia (Foggia, Italy), which operates within the National Health Service. The outcome measures were baropodometry (static exam, dynamic exam, and stabilometric exam), a biometric evaluation system, and the EuroQol 5-Dimension (EQ-5D-5L). RESULTS: Statistical analysis of the data showed how balance affected postural control and how ITRC was able to reduce the body's imbalance and improve quality of life. The vertical angles in frontal projection displayed an increment in the values (head/shoulder, p = 0.009; head/pelvis, p = 0.001; right hip/knee, p = 0.01; right hip/ankle, p = 0.008). In a dynamic analysis, the podalic weight percentage was shown to have a reduction in imbalance on both sides (left side, p = 0.01; right side, p = 0. 01). EQ-5D-5L showed a statistically significant improvement in quality of life and perception of quality of life. Indeed, the health status score improved in all items and in the total rate of the EQ index. In all subjects, walking motility (p = 0.005), self-care (p = 0.002), and habitual activity (p = 0.002) showed statistically significant increments in their values. Pain/discomfort (p = 0.001) and anxiety (p = 0.006) were also reduced. In addition, there was a statistically significant increment in the Visual Analogue Scale (VAS) score (p = 0.001) for life perception. CONCLUSIONS: The ITRC approach showed how small adjustments and postural rebalancing led to a significant improvement in quality of life. ITRC can be considered an effective treatment with good tolerability for a variety of musculoskeletal disorders.
RESUMO
Supporting patients suffering from severe respiratory diseases with mechanical ventilation, obstacles are often encountered due to pulmonary and/or thoracic alterations, reductions in the ventilable lung parenchyma, increases in airway resistance, alterations in thoraco-pulmonary compliance, advanced age of the subjects. All this involves difficulties in finding the right ventilation parameters and an adequate driving pressure to guarantee sufficient ventilation. Therefrom, new mechanical ventilation techniques were sought that could help overcome the aforementioned obstacles. A new mode of mechanical ventilation is being presented, i.e., a Positive + Negative Synchronized Ventilation (PNSV), characterized by the association and integration of two pulmonary ventilators; one acting inside the chest with positive pressures and one externally with negative pressure. The peculiarity of this combination is the complete synchronization, which takes place with specific electronic modifications. The PNSV can be applied both in a completely non-invasive and invasive way and, therefore, be used both in acute care wards and in ICU. The most relevant effect found, due to the compensation of opposing pressures acting on the chest, is that, during the entire inspiratory act created by the ventilators, the pressure at the alveolar level is equal to zero even if adding together the two ventilators' pressures; thus, the transpulmonary pressure is doubled. The application of this pressure for 1 hour on elderly patients suffering from severe acute respiratory failure, resulted in a significant improvement in blood gas analytical and clinical parameters without any side effects. An increased pulmonary recruitment, including posterior lung areas, and a reduction in spontaneous ventilatory rate have also been demonstrated with PNSV. This also paves the way to the search for the best ventilatory treatment in critically ill or ARDS patients. The compensation of intrathoracic pressures should also lead, although not yet proven, to an improvement in venous return, systolic and cardiac output. In the analysis of the study in which this method was applied, the total transpulmonary pressure delivered was the sum of the individual pressures applied by the two ventilators. However, this does not exclude the possibility of reducing the pressures of the two machines to modulate a lower but balanced total transpulmonary pressure within the chest.
RESUMO
INTRODUCTION: There is no evidence in the literature regarding the combined use of positive ventilation with negative ventilation. A recent study reported that the two techniques can be combined in patients with ARDS, who undergo ventilatory support for severe acute respiratory failure (ARF). There is experience of non-invasive ventilation in patients with chronic respiratory diseases and ARF. The aim of this study was to test the efficacy of a non-invasive ventilatory strategy based on the combined use of negative (N) and positive ventilation (P) in bi-level mode (PN). METHODS: We enrolled 8 patients with severe COPD exacerbations and exacerbated chronic respiratory failure admitted in a monitored setting of an intermediate-intensive respiratory Unit. RESULTS: Patients underwent combined positive/negative ventilation and at different times, in place of the two singular ventilation modes (P and N). After each cycle, in the combined P/N ventilatory mode, gas exchanges were significantly increased compared to the two singular P/N mode: pH (7.42 vs 7.40 and 7.40); PCO2 (85.01 vs 72.05 and 66.81 mmHg); FiO2/PO2 (488.75 vs 352.62 and 327.87). All patients well tolerated the application of the double ventilation mode. CONCLUSIONS: In conclusion, the use of dual mode ventilation appears well tolerated and superior to the individual modes in patients with COPD exacerbations and ARF.
