Gastric Decompression Flashcards
purpose of NG tube
- to decompress or drain stomach of fluid/gastric secretions
- instill solutions like meds and feedings into stomach
- used for pt with conditions when peristalsis is absent
reasons for decompression
- rest GI tract
- clear GI tract
- Pt is NPO
why would a pt need to rest the GI tract
-severe vomiting and diarrhea
-diverticulitis, Crohn’s
Monitor GI bleed
why a pt need to clear the GI tract
- treat distention
- intestinal obstruction
- paralytic ileus
- promote healing
types of nasogastric tubes
- levine tube(single lumen)
- salem sump (2 lumen)
levine tube
lacks venting system
mucosal damage can occur when suction is applied
suction is applied intermittently
Salem sump tube
- double lumen
- clear lumen: empties stomach content
- blue lumen: provides continuous flow of air to prevent the clear lumen from pulling stomach lining into tube opening thus preventing gastric mucosal damage
- one way anti reflux vlave may be used in the air flow lumen to prevent reflux of gastric content thru the airflow lumen
- pressre causes the valve to close preventing contents from leaking out the blue
- irrigate with normal saline
enteral nutrition: short term feeding: Nasogastric tube
- nose to stomach
- no for long term feeding
internal nutrition: short term feeding: n’as-duodenal tube
- Nose to duodenum
- thin and flexible tube
enteral nutrition: enterostomal tube: gastrostomy tube
- surgically inserted into stomach from abdominal wall
- use 2-3 days after insetion
enteral nutrition: enterostomal tube: percutaneous endoscopic gastrostomy
- inserted into stomach from abdominal wall
- insertion does not require general anesthesia
- use within hours of insertion
enteral nutrition: enterostomal tube: percutaneous endoscopic jejunostomy
- inserted into jejunum form abdominal wall
- use with stomach problem and delayed gastric emptying
Enteral feeding: feeding infusion: continuous
always used for intestinal feedings
-pump limits mobility
internal feeding: feeding infusion: intermittent
- resembles normal eating schedule
- permits more flexibility and mobility
does a person need to be NPO to have enteral feedings
Can be NPO or not
