Lavage
therapeutic irrigation or washing out of a body cavity or part.This is typically performed in acute-care settings, especially in cases of poisoning or drug overdose for which swift removal of stomach contents is required
-
Lumen
a cavity or bore of a tubular organ or part
-
Air Vent
a device or aperture that allows the entry or exit of air; on a nasogastric tube, a branch of the main tube that is always open to the air, providing continuous atmospheric air irrigation
-
decompression
removal of stomach contents to relieve the stomach and intestines of pressure caused by the accumulation of gastrointestinal air and fluid
-
ileus
mechanical or functional obstruction of the intestines
-
methemoglobin
a non-oxygen-carrying pigment
-
methemoglobinemia
the presence of excessive methemoglobin (a non-oxygen-carrying pigment) in the blood
-
relevant diagnostic data before insertion
coagulation study
-
reasons for topical anesthetic
- -effective pain relief
- -to reduce the risk of nausea and vomiting,
- -to promote successful passage of the
- nasogastric tube
-
TRUE OR FASLE: Auscultation over the stomach while air is irrigated through the nasogastric tube is not a reliable method of assessing placement
- TRUE: you can also hear air over the stomach if the tube has been inserted in
- the lung. If fluid is to be administered though the tube, radiographic
- confirmation is strongly recommended.
-
Purposes of nasogastric intubation
- -to decompress the stomach and remove gas and fluid
- -to lavage the stomach to remove ingested toxins,
- -to diagnose problems with gastrointestinal motility and other disorders,
- -to treat an obstruction,
- -to compress a bleeding site,
- -to aspirate contents for analysis
- -to administer radiographic contrast media to the gastrointestinal tract.
-
Gastric decompression
stomach contents are removed to relieve the stomach and intestines of pressure caused by the accumulation of gastrointestinal air and fluid
-
Indication for Gastric Decompression
bowel obstruction and paralytic ileus and when surgery is performed on the stomach or intestine.
-
Indication for removal of gastric decompression
The tube usually remains in place until normal bowel function resumes, as evidenced by active bowel sounds on auscultation and/or when the patient is able to pass flatus
