Drugs can increase a person's risk of aspiration through multiple mechanisms. [6] Medications including sedatives, hypnotics, and antipsychotics can result in decreased level of consciousness and loss of cough and swallow reflexes. [7] Long-term use of proton pump inhibitors can lead to overgrowth of gastric bacteria and increase risk of ...
Examples include: Sengstaken–Blakemore tube, with three lumens (two balloons and a gastric aspiration port). Pressure can be applied to gastric and esophageal varices by balloon inflation and traction. [1] Linton tube, with a large gastric balloon, and gastric and esophageal aspirates
With the introduction of surfactant treatment for IRDS, Henrik Verder developed additional lung maturity tests based on gastric aspirates (GAS); for example, the microbubble stability test [18] and lamellar body counts (LBC) [19] as well as a large randomised trial using lamellar body counts to guide surfactant treatment. [20]
Aspiration pneumonia most often develops due to micro-aspiration of saliva, or bacteria carried on food and liquids, in combination with impaired host immune function. [30] Chronic inflammation of the lungs is a key feature in aspiration pneumonia in elderly nursing home residents and presents as a sporadic fever (one day per week for several ...
In adults the most common source of aspiration pneumonia is aspiration of oropharyngeal secretions or gastric contents. In children the most common cause is aspiration of infected amniotic fluid, or vaginal secretions. Severe periodontal or gingival diseases are important risk factors for establishment of an anaerobic pleuropulmonary infection.
This avails for aspiration in one lumen, and venting in the other to reduce negative pressure and prevent gastric mucosa from being drawn into the catheter. [5] Dobhoff tube, which is a small bore NG tube with a weight at the end intended to pull it by gravity during insertion. The name "Dobhoff" refers to its inventors, surgeons Dr. Robert ...
Major applications include blood smears, bone marrow aspirates, semen analysis and cytology of various body fluids including urine and cerebrospinal fluid. [7] [8] Microbiologic agents, such as bacteria and fungi, also appear more easily in Diff-Quik. [3] This is useful for the detection of for example Helicobacter pylori from gastric and ...
For practical purposes, gastric pH and endoscopy should be done in someone with suspected achlorhydria. Older testing methods using fluid aspiration through a nasogastric tube can be done, but these procedures can cause significant discomfort and are less efficient ways to obtain a diagnosis.
