Efeitos da Fisioterapia Respiratória na Mecânica Respiratória de Pacientes com Acidente Vascular Encefálico Ventilados Mecanicamente

Patients who went through a Stroke may require mechanical ventilation (MV) in the acute phase of the disease and, on MV, they may show alterations in the respiratory mechanic. Physiotherapy techniques are applied in patients on MV to improve their respiratory mechanic. Thus, the purpose of this study was to evaluate the effects of the Respiratory Physiotherapy into the dynamic compliance (Cdyn), static compliance (Cst) and airway resistance (Rwa) in Stroke patients on MV. In order to do that, patients with Stroke diagnostic on MV were evaluated, before and after the use of Physiotherapy techniques (manual rib-cage compression, thoracic decompression, zero end expiratory pressure and suctioning). Cdyn, Cst and Rwa were the researched variables. Statistical Analysis was made using Paired T-Test with statistical significance with p-values no greater than 5%. Eleven patients were part of the study, with an average of 64,6±12,5 years old. Cdyn increased after physiotherapy from 29,3±16,1 ml/cmH2O to 33,8±16,7 ml/cmH2O (p=0,03). Cst also increased from 44,4±20,7 ml/cmH2O to 54,0±26,6 ml/cmH2O (p=0,024). No significant difference was detected for Rwa between the before and after moments (Before – 8,0±3,2 cmH2O/l/s, After – 7,3±2,25 cmH2O/l/s; p=0,45). It was possible to conclude that both dynamic and static compliance increased after physiotherapy, but the airway resistance did not increase in patients with stroke on mechanical ventilation.

Influência da manobra de descompressão abrupta em pacientes neurológicos

A fisioterapia respiratória em pacientes neurológicos deve ser realizada com critérios e monitorização dos parâmetros hemodinâmicos. O objetivo deste estudo foi avaliar se a fisioterapia respiratória tem efeitos na pressão arterial, pulso e saturação de oxigênio de pacientes neurológicos. Estudamos 12 pacientes com acidente vascular encefálico ou trauma crânio encefálico, independente da idade, divididos em grupos: respiração espontânea (G1) e ventilação mecânica (G2). E as variáveis foram avaliadas antes (M1) e após (M2) a Manobra de descompressão abrupta (MDA). Foram estudadas a Pressão Arterial (PA), Saturação de Oxigênio (SatO2) e Pulso (P). Na estatística foi utilizado o teste t-Student (p < 0,05). Dos pacientes estudados 9 eram do sexo masculino e 3 feminino. As variáveis em G1 e G2 não variaram de forma significativa nos momentos de estudo. Concluímos que a manobra de descompressão abrupta aplicada em pacientes neurológicos não alterou as variáveis hemodinâmicas e de troca.

Envolvimento dos recptores purinérgicos do núcleo parabraquial lateral no controle respiratório

O núcleo parabraquial lateral (NPBL) e o núcleo Kölliker-Fuse (KF) são os mais importantes núcleos da ponte envolvidos com o controle da ventilação pulmonar (VE) e são conhecidos como grupo respiratório pontino ou centro pneumotáxico. Vários experimentos demonstraram que a estimulação ou a lesão do NPBL-KF produziram alterações nos padrões respiratórios. No entanto, ainda não estava claro qual seria a área exata (no complexo NPBL-KF) e o neurotransmissor envolvido nas alterações respiratórias. Estudos com imunohistoquímica demonstraram a presença de receptores purinérgicos (especialmente os P2X) em várias áreas envolvidas com o controle da ventilação, incluindo o NPBL. Estudos também demonstraram a presença de um denso plexo de varicosidades imunorreativas para o GABA ao longo do complexo NPB-KF, sendo que o processamento neural nessa região estaria sob forte inibição gabaérgica. No entanto, o papel dos receptores purinérgicos e gabaérgicos do NPBL na regulação da VE em ratos não anestesiados ainda não tinha sido investigado. Desta forma, no presente estudo investigamos as respostas ventilatórias após a injeção do α,β-metil-ATP (agonista purinérgico), do PPADS (antagonista purinérgico) e do muscimol (agonista GABA-A) no NPBL de ratos não anestesiados. Foram utilizados ratos com cânulas de aço inoxidável bilateralmente no NPBL, os animais foram submetidos a pletismografia de corpo inteiro para que fossem obtidas as medidas de VE. As injeções bilaterais do agonista purinérgico, α,β-metil-ATP (2 nmol/0,2 μl, n=8), no NPBL promoveu queda na freqüência respiratória (fR) (108  5 ciclos/min vs basal 137  6 ciclos/min, p = 0,005), não alterou o volume corrente (VT) (2  0,3 ml/kg vs basal 2  0,3 ml/kg, p = 0,967) e queda na VE (263  42 ml.kg-1.min-1 vs basal 325  43 ml.kg-1.min-1, p = 0,001)...

Amostragem de poluentes particulados emitidos pela queima de biomassa em correntes confinadas

It is clear today the ever-accelerating search for new fuels that will eventually replace those that will survive in our society, which are fossil fuels. For this reason, a fuel used since the dawn of humanity and much studied since then, considered the generator of clean, renewable energy, can earn more and more space in the power generation sector, which is biomass. We performed two experiments with two different types of biomass, one from the Amazon rainforest and other pine and eucalyptus as waste from the sawmill UNESP Itapeva. In the first experiment, conducted at the Laboratory of Combustion and Propulsion INPE Cachoeira Paulista were conducted three tests in a chimney with a fan creating forced ventilation, where the biomass was burned and deposited on a support beneath the hood. In the second experiment was conducted to analyze the emission of particulate matter using biomass (waste) from the sawmill on the campus of UNESP experimental Itapeva the burning of it in a burner for heating water for a wood oven. In these experiments we used a particle called DATARAM4 sampler that is capable of sampling both outdoors and inside of pipelines, which is the focus of this work. With this equipment it was possible to measure the concentration of particulate matter in all the firings as above, and compare them to levels acceptable in the current law, always trying to analyze the so-called fine particles, which are those with diameters less than 2.5 μm. Using data obtained from the equipment was also possible to evaluate the diametral distribution of particulate matter in question, and verify which phases of the flares in the concentration and the diameters of the particles are the most critical. In this work we concluded that in all firings conducted concentrations of particulate matter were higher than that allowed by the law, and the diameters were found that are more harmful to human health

Manejo no incubatório que afeta a eclodibilidade de ovos de galinha (Gallus Gallus Domesticus)

In the process of artificial incubation of fertile eggs of chicken (Gallus gallus domesticus) there are procedures that, they are not hindered the birth, they cause embryonic mortality. Handlings before incubation as disinfection and storage are capable to reduce the embryonic if accomplished of inadequate way viability. Already in the incubation process properly says, irregularities in variables as temperature, turning, humidity and ventilation in the incubator reduce the hatchability, what means that, of the total of fertile eggs there is reduction in the number of born chicks, there is like this the reduction of profit of the incubator, being necessary an analysis of which they interfered in the birth

Natação Adaptada: análise da função pulmonar de pessoas com deficiência

The research discusses the pulmonary function of the students of SORRI that are part of the Project for the extension of the Department of Physical Education in Bauru Swimming for People with Disabilities during the aquatic activities, noting the changes in efficiency class of breathing with the practice of aquatic activity, by the analysis of the volume and respiratory capacity. The respiratory control is essential in the process of adaptation to the liquid medium, because a student who fails to immerse the face in the water will not be able to adopt a horizontal position sufficiently stable. The practice of aquatic activities requires a great effort of breathing. Therefore, the practice of aquatic activities influence favorably the breathing, because the movements performed in the water tone the diaphragm, which is the essential muscle of the breathing, allowing an improvement in pulmonary ventilation. For the purposes of this study, the sample was composed of 10 students of the SORRI of the city of Bauru forming part of the project Swimming for People with Disabilities, practicing swimming once a week for 1 hour. For the collection of lung volumes and capacities was used a transducer of air flow and a unit of data collection, model MP36, both of the brand Biopac connected to a computer, where the data were collected and recorded for later analysis. Two tests were carried out in a day with each participant in the project of swimming, and a test at the beginning of the lesson, at rest, and another after a series of 10 breaths carried out within the swimming pool. These tests were performed in the months of March and April. The analysis of the data was through the medium of the figures and also individually, noting the changes in respiratory function of students practicing aquatic activities, without which there would be no comparison between the participants. The measurements of the scores on the pre- and post-exercise show that the...
