1/2. Negative pressure pulmonary oedema in the medical intensive care unit.OBJECTIVE: Negative pressure pulmonary oedema (NPPE) occurring in the medical intensive care unit (MICU) is an uncommon, probably under-diagnosed, but life-threatening condition. DESIGN: Retrospective data collection. SETTING: Medical intensive care unit in a 1,500-bedded tertiary care hospital. patients AND PARTICIPANTS: Five patients were diagnosed between January 1998 and January 2002. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: Five patients were diagnosed to have NPPE from different aetiologies. These were acute epiglottitis, post-stenting of right bronchus intermedius stenosis, strangulation, compression from a goitre and one patient developed diffuse alveolar haemorrhage after biting the endotracheal tube during recovery from anaesthesia. All patients responded rapidly to supplemental oxygen, positive pressure ventilation and correction of underlying aetiologies. Pulmonary oedema resolved rapidly. CONCLUSIONS: There is a large spectrum of aetiologies causing NPPE in the medical intensive care unit.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/2. A patient presenting for pharyngeal biopsy.A 68-yr-old man presented for pharyngeal biopsy under general anaesthesia. Coincidentally he was found to have a large mediastinal mass. The evaluation of this patient is described. The exact risk of catastrophic airway collapse on induction of anaesthesia in patients with mediastinal masses is controversial but probably small. As there is no test to prevent airway collapse, it is suggested that attempts at biopsy be performed with regional anaesthesia after radiotherapy.- - - - - - - - - - ranking = 3keywords = anaesthesia (Clic here for more details about this article) |
