The number of indications for lung collapse during different procedures is rising. Difficult upper airway is more often encountered with the need for single lung ventilation. In patients with difficult airway, the safest approach is by placing a single-lumen endotracheal tube with the aid of a flexible fiberoptic bronchoscope. Lung isolation in these patients is then achieved by means of a bron...

Objectives- Recording intraoperative cardiorespiratory events in thoracoscopic total pericardiectomy via transdiaphragmatic camera port in dog to evaluate feasibility and risks of mechanical stimulation of pherenic nerve during this surgical approach.Design- Technical assessment, experimental study.Animals- Nine healthy, male mixed breed dogs.Procedures- Under one lung ventilation inhalation ge...

One-lung ventilation is used during a variety of surgical procedures, even in patients with pre-existing coronary artery disease. The study purpose was to elucidate if myocardial metabolism crosses the anaerobic threshold under hypoxemia during one-lung ventilation. Therefore, we determined myocardial metabolism as a marker for anaerobic myocardial metabolism in patients with significant multi-...

A recently developed endotracheal tube with a movable bronchial blocker (Univent tube) was used for single lung ventilation. A total of 50 intubations were undertaken for a wide variety of thoracic procedures. Each case was analyzed with respect to ease or difficulty of intubation, tube dislodgment, efficacy of lung collapse, and adequacy of single lung ventilation. Successful, safe selective i...

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...

H YPOXEMIA that may reasonably be defined by an arterial hemoglobin oxygen saturation of less than 90% occurs in 5–10% of patients during one-lung ventilation (OLV). The physiopathology of hypoxemia is complex, and the management of intraoperative hypoxemia during OLV remains a challenge for anesthesiologists. In life-threatening hypoxemia, correct oxygenation should be restored rapidly. This m...

Video-assisted thoracoscopic surgery for pediatric patients has gained popularity due to better outcomes than open surgery. For this procedure, one-lung ventilation may be necessary to provide an adequate surgical field. Confirming lung isolation is crucial when one-lung ventilation is required. Recently, we experienced a case in which one-lung ventilation was confirmed by ultrasonography using...
