	Postgraduate Medicine: Aspiration pneumonia
		Aspiration pneumonia most often occurs in the presence of impairment of protective upper and lower airway reflexes in patients who have a decreased level of consciousness or central nervous system disease.
		Whether aspiration pneumonia develops after an episode of aspiration is determined by the volume of material aspirated, its character (eg, acidic versus neutral, liquid versus particulate, infected versus sterile), the frequency of aspiration episodes, and the adequacy of host defenses.
		Patients with hospital-acquired aspiration pneumonia may be treated with cefepime hydrochloride (Maxipime) or ceftazidime plus clindamycin or metronidazole; a beta-lactam and beta-lactamase inhibitor combination such as ampicillin and sulbactam, piperacillin sodium and tazobactam sodium (Zosyn), or ticarcillin and clavulanate potassium (Timentin); or a newer fluoroquinolone.

	Pulmonary aspiration - Wikipedia, the free encyclopedia
		As the right main bronchus is more vertical and of slightly wider lumen than the left, aspirated material is more likely to end up in this branch or one of its subsequent bifurcations.
		During labor, early respiratory movements by the baby facilitate filling of alveolar ducts and alveolar lumens with elements of amniotic fluid: amniotic cells, squames and squamous cells from fetal skin, lanugo, meconium.
		The location of abcesses caused by aspiration depends on the position one is in.

		In medicine, aspiration is the passing of secretions or foreign bodies through the trachea, and possibly into the lungs.
		Significant aspiration can only occur if the protective reflexes are absent (in neurological disease, coma, or general anesthesia).
		Measures to prevent aspiration depend on the situation and the individual patient, with endotracheal intubation often being necessary.

	American Journal of Respiratory and Critical Care Medicine: Meconium aspiration syndrome: Is surfactant lavage the ...
		Aspiration of meconium typically occurs after fetal hypoxic/ ischemic stress leading to intestinal peristalsis, meconium contamination of the amniotic fluid, and gasping respirations that draw the noxious meconium-stained fluid deep into the fetal lung.
		In the most severe cases of meconium aspiration syndrome in newborns, airway and alveolar dysfunction is accompanied by compromised cardiac performance, causing shock and marked pulmonary vascular abnormalities developed over time in utero, leading to severe pulmonary hypertension.
		Survival with meconium aspiration syndrome in the current era of extracorporeal life support, however, is approximately 95%, suggesting that the structural and functional abnormalities of the pulmonary vascular bed that occur in utero may undergo rapid resolution after the fetus is removed from a physiologically hostile environment.

		William O. Roberts, MD njection and aspiration of a knee joint is a useful procedure for the office, especially in a practice involving many physically active patients.
		To date, the most common applications of knee aspiration in younger athletes are the analysis of joint fluid in the suspected septic joint and the removal of joint fluid to confirm a loss of extension in the presence of a traumatic effusion.
		A 16- or 18-gauge needle is required to aspirate thick joint fluid or purulent exudate; thus, if the joint is to be aspirated for culture, crystals, or blood, use local anesthesia (1% lidocaine mixed with 7.5% sodium bicarbonate in a 9:1 ratio) to permit use of the larger needle.

	Aspiration Pneumonia: Current Concepts and Approach to Management
		The clinical response to aspirated material is dependent on the interplay between the characteristics of the aspirate and those of the host.
		Aspiration of pathogens from a previously colonized oropharynx is the primary pathway by which organisms gain entrance to the lungs, and therefore, in a broad sense, most pneumonias, are aspiration-related.
		In this study, the volume of the aspirate was directly related to pneumonia risk: 43% of patients with mild aspiration (thin liquid aspirations) developed pneumonia, compared with 67% of patients with severe aspiration (all consistencies aspirated with almost every swallow).

		Fraser's group found that moderate/severe meconium aspiration syndrome or infant death occurred in 44 infants of women in the amnioinfusion group, and in 35 infants of women in the standard care group.
		It is very likely that infants have aspirated meconium before the condition is recognized, and that is part of the reason that amnioinfusion doesn't work, said Dr. Michael Ross, a professor of obstetrics and gynecology and public health at the University of California, Los Angeles School of Medicine.

	Archives of Pathology & Laboratory Medicine: Aspiration cytology of papillary hyperplastic thyroid nodule / In reply (Site not responding. Last check: 2007-11-04)
		To the Editor.-While reading the recent article by Khurana et al1 discussing the aspiration cytology pattern in 3 pediatric patients with solitary papillary hyperplastic thyroid nodules, one is compelled to come to the conclusion that there were not only potential pitfalls, as the authors mention in the subtitle of their article, but several dangerous pitfalls.
		As a matter of fact, the rationale of performing fine-needle aspiration biopsy (FNAB) of a thyroid nodule already having evidence of hyperfunction (case 1) is unclear.
		Increasing reliance on the diagnostic accuracy of thyroid fine-needle aspiration biopsy in selection of pediatric patients for surgery makes it imperative that a continuous effort is made to refine the cytologic criteria of lesions that may result in false-positive diagnosis and unnecessary surgical intervention.
