background: extubation is associated with the risk of complications such as accumulated secretion above the endotracheal tube cuff, eventual atelectasia following a reduction in pulmonary volumes because of a lack of physiological positive end expiratory pressure, and intra-tracheal suction. in order to reduce these complications, and, based on basic physiological principles, a new practical ex...

The aim of the present study was to compare the evolution of pulmonary haemodynamics and of arterial blood gases in chronic obstructive pulmonary disease (COPD) patients with mild-to-moderate hypoxaemia, with or without sleep-related oxygen desaturation. COPD patients with daytime arterial oxygen partial pressure in the range 56-69 mmHg were included prospectively. Sleep-related oxygen desatura...

BACKGROUND Aim of this prospective experimental study was to assess effects of systemic hypoxemia and hypovolemia on global and gastrointestinal oxygenation and perfusion in anesthetized horses. Therefore, we anesthetized twelve systemically healthy warmblood horses using either xylazine or dexmedetomidine for premedication and midazolam and ketamine for induction. Anesthesia was maintained usi...

conclusions oxygen therapy in the case group had no significant impact on protection from dgf. results forty living kidney transplantations including 17 cases and 23 controls were performed; female gender was more prevalent in recipients (n = 16, 40%). the mean age of recipients was 36.1 ± 12.4 (18-67) years old. dgf was detected in 2 (5.95%) individuals, from whom one was in the case group and...

BACKGROUND Although oxygen is generally administered in a liberal manner in the perioperative setting, the effects of oxygen administration on dynamic cardiovascular parameters, filling status and cerebral perfusion have not been fully unraveled. Our aim was to study the acute hemodynamic and microcirculatory changes before, during and after arterial hyperoxia in mechanically ventilated patient...

Acute poliomyelitis occurs in all trimesters of pregnancy. At one time there were six women in the poliomyelitis ward at Children's Hospital, five of whom were either pregnant or recently delivered. Poliomyelitis is an important entity in the differential diagnosis of diseases complicating pregnancy. Once diagnosed, treatment is directed primarily toward the symptoms of poliomyelitis, secondari...

A rise in cardiac output and a fall in arterial oxygen tension are well known side effects of bronchodilator drugs, particularly beta-adrenergic agonists. In recent years, fenoterol (Berotec), an effective beta-adrenergic agonist, has been used at increasing rates in asthmatic subjects, as well as in patients with chronic obstructive pulmonary disease (COPD). The effects of fenoterol on systemi...

R ECENT ADVANCES in aircraft design have made possible attainment of altitudes in which man is unable to live, even while breathing pure oxygen. This difficulty has been overcome by the development of pressurized cabins and, to some extent, by the use of pressure-breathing equipment. The latter effectively increases alveolar oxygen tension; however, there has been some uncertainty as to whether...
