conclusions: the effects of propofol on hemodynamics and arterial oxygen pressure during one- or two-lung ventilation were not different from those of isoflurane. results: sixty patients (mean age = 4124.18 ± 18.63 years) were divided into two groups. the age and gender of the subjects were not statistically different between the two groups. in the propofol group, the arterial oxygen pressure d...

In recent years, laser resection of lung metastases has been established as the standard procedure worldwide. To avoid airway fire, it is necessary to collapse the surgical lung. The selective lobar bronchial blockade is a technique that allows one-lung ventilation while the operated lobe is collapsed in patients with previous pulmonary resection requiring subsequent resection or with limited p...

BACKGROUND Domiciliary non-invasive ventilation may be used in palliative care of patients with chronic obstructive pulmonary disease, although there is uncertainty regarding effect on quality of life. AIM Explore experiences of domiciliary non-invasive ventilation in chronic obstructive pulmonary disease, to understand decision-making processes and improve future palliative care. DESIGN Qu...

To determine whether liquid ventilation (LV) causes less cell injury and improves lung function compared with conventional gas ventilation (GV), we analyzed pulmonary physiological profiles, lung histology, and cell death in 110- and 120-day preterm lambs, which were randomized to receive either ventilation modality on FI(O(2)) = 1. LV lungs were well expanded with adequate pulmonary function, ...

Central haemodynamics in 23 patients with mitral stenosis and 7 control subjects were compared with the results of regional lung perfusion studied by (133)Xe, pulmonary scintigraphy with (99)mTc-labelled macro-aggregates of albumin, and regional ventilation by (133)Xe.A close correlation was found between both methods assessing regional pulmonary perfusion, i.e. pulmonary scintigraphy and (133)...

PURPOSE Childhood post-infectious bronchiolitis obliterans (BO) is an infrequent lung disease leading to narrowing and/or complete obliteration of small airways. Ventilation and perfusion (V/Q) scan can provide both regional and global pulmonary information. However, only few retrospective researches investigating post-infectious BO involved V/Q scan, the clinical value of this method is unknow...

INTRODUCTION: Pulmonary ventilation is an important marker in obstructive lung diseases, and its non-invasive imaging can provide useful information to investigate the onset and severity of these pulmonary disorders, as well as to assess response to therapy. Hyperpolarized gas MRI has provides a sensitive and noninvasive platform to directly image distribution of respiratory gas at a high resol...

An automated computer analysis of ventilation-perfusion lung scans was used to derive graphical data from lung scans of 11 patients with acute minor pulmonary embolism, free of pre-existing cardiorespiratory disease, and with no evidence of intrapulmonary complication or pleural effusion. In each case the analysis showed the presence of areas of lung, remote from those affected by the pulmonary...

OBJECTIVES Newborns with pulmonary infection frequently present with acute lung injury leading to ventilation/perfusion abnormalities in which intravenous delivery of antibiotics to the lung can be suboptimal. Tidal liquid ventilation (TLV) has been shown to be an effective means for delivering drugs directly to the pulmonary system. The objective of this study was to compare, with lung injury,...

UNLABELLED Unilateral pulmonary artery agenesis without any cardiovascular malformation is a rare anomaly. We present the imaging findings of a patient who was diagnosed as isolated left pulmonary artery agenesis. A 27-year-old female patient was admitted to our hospital due to dyspnea during exercise for five years. Chest X-ray revealed minimally small left pulmonary hilum and left lung. She w...
