13. Análise hemogasométrica arterial e venosa de ovinos submetidos à transposição carotídea e indução de desequilíbrios ácido-básicos
With the purpose of comparing the parameters of arterial and venous blood gases during inhalational anesthesia with isoflurane in acid-base induced imbalances, 6 sheep Santa Inês were used. To facilitate the serial collection of blood they were prior submitted to carotid transposition technique used by Sweeney and Constantinescu (1992) in horses. We evaluat

14. Epidural morphine or tramadol administration in dogs: analgesic and cardiopulmonary effects / Administração peridural de morfina ou tramadol em cães: efeito analgésico e cardiorespiratório
This double-blind study compared the analgesic and cardiopulmonary effects of the peridural morphine or tramadol in bitches submitted to ovariohisterectomy. Dogs were randomly assigned to three groups of 08 animals each and received morphine (0.1mg.kg-1 GM), tramadol (2mg kg-1 GT) or a saline placebo (0.2ml.kg-1 GS). Pre-anaesthetic medication was acepromazi

15. Effects of the physical activity on the vasculo-alveolar complex of the rats lung / Efeitos da atividade física aeróbia no complexo vásculo-alveolar no pulmão de ratos
The cardiovascular system is subject to important autonomic and haemodynamic adaptation by virtue of regular physical training. The aim of this study was to describe the effects of a treadmill physical training on the alveolar cytoarchitecture of the rats lung from a morphoquantitative and functional point of view. Additional aims were to quantify the heart

16. Antiretroviral agents and acid-base balance at delivery of the neonate
Limited evidence is available regarding antiretroviral (ARV) safety for uninfected infants exposed to these drugs in utero. Our objective was to determine if ARV administered to pregnant women is associated with decreasing umbilical arterial pH and base excess in uninfected infants. A prospective study was conducted on 57 neonates divided into three groups:

17. Mechanisms underlying gas exchange alterations in an experimental model of pulmonary embolism
The aim of the present study was to determine the ventilation/perfusion ratio that contributes to hypoxemia in pulmonary embolism by analyzing blood gases and volumetric capnography in a model of experimental acute pulmonary embolism. Pulmonary embolization with autologous blood clots was induced in seven pigs weighing 24.00 ± 0.6 kg, anesthetized and mecha

18. INFLUENCE OF THE RESPIRATORY FREQUENCY ON THE ARTERIAL GASES SANGUINEOUS IN POSTOPERATIVE THE IMMEDIATE ONE OF EXPLORING LAPAROTOMIA FOR ABDOMINAL TRAUMA / A INFLUÊNCIA DA FREQUÊNCIA RESPIRATÓRIA SOBRE OS GASES SANGUÍNEOS ARTERIAIS NO PÓS - OPERATÓRIO IMEDIATO DE LAPAROTOMIA EXPLORADORA POR TRAUMA ABDOMINAL
The incidence of post-operative pulmonary complications is large, in consequence of the manipulation of abdominal cavity with changes on pulmonary volumes and capacities, resulting in atelectasis and hypoxemy. Alteration of breath pattern in association with postoperative pain can interfere in gaseous exchanges with larger repercussions in the presence of ri

19. A INFLUÊNCIA DA FREQUÊNCIA RESPIRATÓRIA SOBRE OS GASES SANGUÍNEOS ARTERIAIS NO PÓS - OPERATÓRIO IMEDIATO DE LAPAROTOMIA EXPLORADORA POR TRAUMA ABDOMINAL / INFLUENCE OF THE RESPIRATORY FREQUENCY ON THE ARTERIAL GASES SANGUINEOUS IN POSTOPERATIVE THE IMMEDIATE ONE OF EXPLORING LAPAROTOMIA FOR ABDOMINAL TRAUMA
A incidência de complicação pulmonar pós-operatória é grande, decorrente da manipulação da cavidade abdominal com modificação dos volumes e capacidades pulmonares e resultando em hipoxemia e atelectasia. Alteração do padrão respiratório juntamente com a dor no pósoperatório podem interferir nas trocas gasosas com maiores repercussões na pres

20. Mecanismos que interferem no intercambio gasoso no tromboembolismo pulmonar experimental / Mechanisms underlying gas exchange alterations in an experimental model of pulmonary embolism
The literature broadly approaches the mechanisms responsible for the genesis of the hypoxemia in pulmonary embolism (PE). The aim of this study is to analyze the ventilation/perfusion ratio, which contributed to the hypoxemia in PE by analyzing blood gases and volumetric capnography in a model of experimental acute PE. Pulmonary embolization with autologous

21. Repercussões nos gases sanguíneos de recém-nascidos prematuros com síndrome do desconforto respiratório e sob ventilação mecânica convencional após ajuste no tempo inspiratório em função da constante de tempo
Were evaluated twenty-five neonates with less than 2000 grams of birth weight and gestational age lesser than thirty-five weeks, diagnosed with respiratory distress syndrome, on conventional mechanical ventilation, treated with exogenous surfactant and were at first seventy-two hours of life. With the use of a pneumotachometer associated to ventilator were p

22. A model of the carbon monoxide transport in the respiratory system of the human body. / Um modelo do transporte de monóxido de carbono no sistema respiratório do corpo humano.
This work is about the transport of carbon monoxide in the human body. The carbon monoxide is a colorless, odourless and tasteless gas and the main cause of accidental deaths for poisoning. It is responsible for the biggest amount of pollutant launched in the atmosphere. When inspired, it occupies places destined to the oxygen transport, with affinity about

23. Evaluation of epidural or systemic tramadol and epidural morphine in bitches submitted to ovariohysterectomy / Avaliação do emprego do tramadol epidural ou sistêmico e da morfina epidural em cadelas submetidas à ovariohisterectomia
The aim of this study was to compare epidural or systemic tramadol and morphine to control postoperative pain in bitches submitted to ovariohysterectomy and to determine the effects of treatments on cardio and respiratory systems as well as side effects. Forty female dogs were randomly divided into four groups. Group 1 received 2 mg/kg of epidural tramadol,

24. RepercussÃes cardio-respiratÃrias da manobra de recrutamernto alveolar em cÃes submetidos à lesÃo pulmonar aguda unilateral
Cardiopulmonary repercussion from Alveolar Recruitment Maneuver (ARM) was analysed in dogs, which had undergone right acute lung injury (ALI) induced by 0.9% saline solution lavage warmed at 38o C. ALI group (n=6) had undergone a right ALI, while in ARM group (n=6), underwent recruitment maneuver after induction unilateral ALI. Respiratory mechanical paramet
