We describe two otherwise healthy subjects with many years sequelae due to lung aspiration. In both, diagnosis was delayed due to lack of history of aspiration. Recurrent pneumonia in the same segment in one, and migratory pneumonia in the other, could have suggested the diagnosis. Review of the literature shows that occult foreign body aspiration poses difficulties in diagnosis and that often ...

OBJECTIVES To determine the prevalence of aspiration in patients with newly diagnosed nontreated advanced head and neck cancer and to determine the ability of the clinical examination to predict aspiration in this patient population. DESIGN A descriptive prevalence study of the presence of aspiration in patients with advanced (stages III and IV) head and neck cancer and a prospective correlat...

Background: Aspiration pneumonia is a rare but serious complication that carries significant morbidity following surgery. This study was undertaken to identify pre-operative and operative risk factors and develop a predictive model for aspiration pneumonia in cardiac surgery patients. Methods: This study was a retrospective analysis of our institution’s Society of Thoracic Surgeons’ (STS) cardi...

CONTEXT Many patients in use of mechanical ventilation show clinical complications due to tracheal aspiration. Assessment and early methods are necessary, so that preventive and safety measures apply to this patients. OBJECTIVE To study the incidence of tracheal aspiration of saliva in tracheotomized patients treated in intensive care unit using two modes of mechanical ventilation and with di...

OBJECTIVE To determine the major risk factors and abnormal videofluoroscopic swallowing study (VFSS) findings associated with aspiration in patients with head and neck cancer (HNC). METHOD Risk factors associated with aspiration were investigated retrospectively in 241 patients with HNC using medical records and pre-recorded VFSS. Age, gender, lesion location and stage, treatment factors, and...

The assessment of pre-procedure fasting and control of sedation depth are prominent elements of widely disseminated procedural sedation guidelines and of the Joint Commission on Accreditation of Healthcare Organizations' standards. Both exist primarily to minimize the risk of pulmonary aspiration of gastric contents. This paper critically examines the literature on pre-procedure fasting and con...

Background: International guidelines recommend two hours of clear fluid fasting prior to general anesthesia. The pediatric anesthesia unit of Uppsala University Hospital implements a more liberal fasting regime for more than a decade; thus children scheduled for elective procedures are allowed to drink clear fluids until called to theatre. We hypothesized that this practice would not increase t...

BACKGROUND Hydrosalpinges have adverse effects on IVF outcomes. Salpingectomy is effective in improving outcomes, but it is not always practical or safe. Ultrasound-guided aspiration of hydrosalpinges at oocyte collection is an option for those who develop hydrosalpinges during controlled ovarian stimulation; however, there is no randomized evidence to show whether this practice is effective. ...

There have been many studies on glass particle contamination from glass ampules during the injection of glass ampules, but only the contamination from direct IV bolus injection has been measured. This research aimed to study the difference in glass particle contamination from ampules with different intravenous administration methods commonly used in clinical practice. Four methods were studied:...
