OBJECTIVE: Foreign body aspiration (FBA) is a serious problem in children. While bronchoscopy should be performed in all patients with aspiration; patients without aspiration should be carefully excluded to avoid an unnecessary bronchoscopy. In this study we analyzed the details of our series, complication rates and compared the diagnostic findings ...

We describe here the clinical manifestations of platypnea-orthodeoxia in two patients with interatrial shunting. In both cases, the patients were asymptomatic prior to developing additional cardiopulmonary issues that apparently enhanced right-to-left intracardiac shunting. The patients were both treated with percutaneously deployed occlusion devices, with excellent results. Symptoms and positional oxygen ...

PURPOSE: The failure to maintain a patent airway after the induction of general anesthesia is a major concern for anesthesiologists. For securing the airway, tracheal intubation using direct laryngoscopy remains the method of choice in most cases. However, direct laryngoscopic intubation is difficult in 1% to 4%, and impossible in ...

Anesthesia for ankylosing spondylitis (AS) patients with difficult airway is of great stress to anesthesiologists. If tracheal intubation is not mandatory for general anesthesia, laryngeal mask airway (LMA) may suffice for adequate ventilation. Yet, in certain circumstances, no one can guarantee that LMA will reliably serve the purpose in surgical ...

PURPOSE OF REVIEW: The article reviews the evidence for and against early intubation for brain-injured patients. RECENT FINDINGS: Although theoretical advantages to early intubation include airway protection, improved oxygenation, and control of ventilation, recent clinical data document an association between early intubation and mortality. This likely reflects some degree of ...

Down syndrome (DS) may be associated with various organ system disorders. Feeding problems are frequent in children with DS and may be caused by associated defects, including congenital heart defects, gastrointestinal defects, or endocrine disorders. In the absence of these associated conditions, feeding problems are often attributed to general hypotonia. ...

We discus the case of a forty-nine year old patient with haloperidol induced laryngeal dystonia (LD). Laryngeal dystonia is a life threatening, very rare medical condition which is difficult to diagnose. It can occur after a short treatment of a patient with atypical antipschycotics. LD can induce severe respiratory insufficiency ...
