conclusions this report presents a new method for lung isolation in specific cases and in the absence of certain equipment. case presentation a 41-year-old woman with a history of pharyngo-laryngo-oesophagectomy (plo) and tracheostomy was a candidate for thoracic duct ligation because of chylothorax. since the patient had tracheostmy stomal stenosis, two cuffed tracheal tubes (internal diameter...

conclusions we found that 0.3 mcg/kg of sufentanil attenuates cardiovascular responses to double-lumen endobronchial intubation without adverse effects. background sufentanil is a potent opioid analgesic frequently used in clinical anesthesia. double-lumen endobronchial intubation induces profound cardiovascular responses in comparison with ordinary endotracheal intubation because of the larger...

lung contusion is an entity involving injury to the alveolar capillaries, without any tear or cut in the lung tissue. this results in accumulation of blood and other fluids within the lung tissue. the excess fluid interferes with gas exchange leading to hypoxia. the pathophysiology of lung contusion includes ventilation/perfusion mismatching, increased intrapulmonary shunting, increased lung wa...

variability of tidal volume and respiratory rate in normally breathing man has long been demonstrated [1]. however because of lack of knowledge and technology primary ventilators could only deliver a fixed tidal volume in a fixed rate the so called volume controlled ventilation (vcv). vcv was volume preset time triggered and cycled and there was no synchronization with patient’s breaths. at tha...

conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...

deep vein thrombosis (dvt) is an important life threatening condition that is difficult to diagnose, particularly in the early stages. looking for dvt in lower limb can be considered ancillary in suspected cases of pulmonary embolism (pe) indirectly highlighting a cause and effect relationship of a single disease (i.e cause being dvt and effect is the assault on the lung vasculature). prompt an...

hypoxia is a major concern for human health. multiple new techniques were proposed for tissue oxygenation in different variety of patients.  clark jr. et al. presenting their article titled “fluorovent: a new perfluorocarbon for liquid ventilation”, at a symposium in neonatology, in 1995, described the scientific importance for perfluorocarbons which would be ideally suited for use in liquid ve...

a 21-year old man with cervical spinal cord damage due to diving was admitted in the icu. tracheostomy was performed due to prolonged mechanical ventilation. left lung atelectasis happened frequently. because of the difficulty of bronchoscopy and failing of recruitment, using a double lumen, two tracheal tubes were guided into the left and right lungs through the tracheostomy stoma site. after ...

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...

results sixty patients were involved in this study. in asv mode, values including peak airway pressure (p-peak), end-tidal carbon dioxide (etco2), tidal volume and respiratory dead space were significantly lower than simv mode. although the mean value for dynamic compliance had no significant difference in the two types of ventilation, it was better in asv mode. methods in a crossover study, pa...
