Lung computed tomography density distribution in a porcine model of one-lung ventilation.
BACKGROUND One-lung ventilation (OLV) exposes the dependent lung to increased mechanical stress which may affect the postoperative course. This study evaluates regional pulmonary gas/tissue distribution in a porcine model of OLV. METHODS Nine anaesthetized and mechanically ventilated (V(T)=10 ml kg(-1), FI(O(2))=0.40, PEEP=5 cm H(2)O) pigs were studied. After lung separation by an endobronchi...
متن کاملQuantitative computed tomography in porcine lung injury with variable versus conventional ventilation: recruitment and surfactant replacement.
OBJECTIVES Biologically variable ventilation improves lung function in acute respiratory distress models. If enhanced recruitment is responsible for these results, then biologically variable ventilation might promote distribution of exogenous surfactant to nonaerated areas. Our objectives were to confirm model predictions of enhanced recruitment with biologically variable ventilation using comp...
متن کاملIndependent Lung Ventilation and One Lung Ventilation
The application of the independent lung ventilation (ILV) in adults has been described by Carlon and co-workers in 1978 and subsequently by other investigators. In 1983 Hedenstierna and coworkers using a bilumen tube suitable for prolonged intubation, and two Servo Ventilator 900 B (Siemens) adapted for synchronization, treated a wide range of clinical conditions. Following this experience, the...
متن کاملLung Lesions Biopsy in Children by Computed Tomography (CT) Fluoroscopy Guided Versus Conventional CT Scan Guided
Abstract Background Computed tomography (CT)-guided biopsy of the lung is a well-established method of diagnosis. The aim of this study was to determine the success rate of fluoroscopic CT (FCT) and conventional CT (CCT) in needle navigation biopsies from the lung lesions. Materials and Methods A total of 78 patients were prospectively enrolled to receive CT-guided biopsy with (group I, n=2...
متن کاملLung growth and computed tomography.
Studies on normal lung development have shown that all airways are present by halfway through gestation, and approximately one-third to one-half of the adult number of alveoli develop during the last trimester of pregnancy [1, 2]. Modern treatment of premature babies born with immature lungs has led to the survival of a large cohort of infants and children who may have an abnormal lung or one t...
