NCT00986869
Background Flexible bronchoscopy (FB) is one of the most common invasive procedures performed by pulmonologists (1) . Typically performed under topical anesthesia and conscious sedation, the procedure is considered to be safe, effective and well tolerated in patients with a wide variety of pulmonary diseases (2). Complications associated with the procedure are rare and studies have estimated an incidence of 0.5-4% (3) The most commonly recognized complications include hypoxia, bleeding, bronchospasm, cardiac dysrhythmias, pneumothorax, and vagal reactions (4). Several conditions increase the risk of complications including pre-existent hypoxemia, use of mechanical ventilation, uremia, profound thrombocytopenia, coagulopathy and pulmonary hypertension (PH) (5). Although previous reports suggest that transbronchial biopsies increase the risk for hemorrhage in this population, data are is limited to survey analyses and isolated reports. Recently Guzman et al. reported a retrospective analysis about the safety of FB in PH. (6) They found that FB can be performed safely in patients with mild and moderate PH. However, the study was small and retrospective analysis. Furthermore, there is no consensus regarding levels of pulmonary artery pressure (PAP) considered to be safe for invasive diagnostic interventions such as TBLB or transbronchial needle aspiration. Objective To assess the safety of FB in patients with PH and to study the occurrence of complications associated with different diagnostic bronchoscopic procedures.
NCT01125306
Xal-Ease is a novel Pfizer-Pharmacia device aimed to significantly facilitate the Xalatan/Xalacom instillation and to avoid loss of Xalatan/Xalacom eye drops due to incorrect instillation. Patients on Xalatan/Xalacom who have consumed more than one bottle per month within a year according to consumption data drawn from the Clalit Health Services database, will use the Xal-Ease device for a year. The device is expected to reduce consumption of bottles and result in saving money for both patients and medical care providers.
