Opis:
Early physiotherapy is an important part of the comprehensive treatment of patients after major abdominal surgery (MAS). Accelerated mobilization should be safe and requires the use of appropriate techniques. Most of the physiotherapists and surgeons recommends using abdominal belts. Opponents claim that belts have an adverse effect on lungs ventilation. The aim of the study was to determine the effect of abdominal belt on lung ventilation efficiency in the early period after MAS. Material and methods. The study involved 20 patients after MAS. Including 9 women and 11 men, aged between 40 to 90 years (xˉ 66.7). In the scheduled 7 patients and urgent 13. All of them were in the early period after surgery. Dynamic spirometry was performed twice in the postoperative period. For the first time wearing a belt, and then without the belt in the same group. Evaluated the forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and peak expiratory flow (PEF). For the analysis uses the Wilcoxon matched-pairs test and Spearman’s rank correlations. P values <0.05 were considered significant. Results. The value of the ventilation indicators measured wearing abdominal belt were slightly lower than the values evaluated without the belt. The results are shown in percent predicted for age and gender, FEV wearing belt 52%, without belt 53%; FEV1 59% vs 61%; PEF 46% vs 51%. There were no statistically significant differences Conclusions. There were no significant negative influence of abdominal belt on lungs ventilation in early period after MAS. There was no correlations between age, body mass index and changes in ventilation indicators.

Opis:
A complex model of mechanically ventilated ARDS lungs is proposed in the paper. This analogue is based on a combination of four components that describe breathing mechanics: morphology, mechanical properties of surfactant, tissue and chest wall characteristics. Physical-mathematical formulas attained from experimental data have been translated into their electrical equivalents and implemented in MultiSim software. To examine the adequacy of the forward model to the properties and behaviour of mechanically ventilated lungs in patients with ARDS symptoms, several computer simulations have been performed and reported in the paper. Inhomogeneous characteristics observed in the physical properties of ARDS lungs were mapped in a multi-lobe model and the measured outputs were compared with the data from physiological reports. In this way clinicians and scientists can obtain the knowledge on the moment of airway zone reopening/closure expressed as a function of pressure, volume or even time. In the paper, these trends were assessed for inhomogeneous distributions (proper for ARDS) of surfactant properties and airway geometry in consecutive lung lobes. The proposed model enables monitoring of temporal alveolar dynamics in successive lobes as well as those occurring at a higher level of lung structure organization, i.e. in a point P0 which can be used for collection of respiratory data during indirect management of recruitment/de-recruitment processes in ARDS lungs. The complex model and synthetic data generated for various parametrization scenarios make possible prospective studies on designing an indirect mode of alveolar zone management, i.e. with a minimized risk of repeated alveolar recruitment/de-recruitment and mechanical overstraining of lung tissues.
