1

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

2

reasons for decompression

-rest GI tract
-clear GI tract
-Pt is NPO

3

why would a pt need to rest the GI tract

-severe vomiting and diarrhea
-diverticulitis, Crohn's
Monitor GI bleed

4

why a pt need to clear the GI tract

-treat distention
-intestinal obstruction
-paralytic ileus
-promote healing

5

types of nasogastric tubes

-levine tube(single lumen)
-salem sump (2 lumen)

6

levine tube

lacks venting system
mucosal damage can occur when suction is applied
suction is applied intermittently

7

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

8

enteral nutrition: short term feeding: Nasogastric tube

-nose to stomach
-no for long term feeding

9

internal nutrition: short term feeding: n'as-duodenal tube

-Nose to duodenum
-thin and flexible tube

10

enteral nutrition: enterostomal tube: gastrostomy tube

-surgically inserted into stomach from abdominal wall
-use 2-3 days after insetion

11

enteral nutrition: enterostomal tube: percutaneous endoscopic gastrostomy

-inserted into stomach from abdominal wall
-insertion does not require general anesthesia
-use within hours of insertion

12

enteral nutrition: enterostomal tube: percutaneous endoscopic jejunostomy

-inserted into jejunum form abdominal wall
-use with stomach problem and delayed gastric emptying

13

Enteral feeding: feeding infusion: continuous

always used for intestinal feedings
-pump limits mobility

14

internal feeding: feeding infusion: intermittent

-resembles normal eating schedule
-permits more flexibility and mobility

15

does a person need to be NPO to have enteral feedings

Can be NPO or not

16

common complications of feedings and NGT

-aspiration
-clogged tube
-nasal erosion
-diarrhea
-unplanned removal
-stomach infection (GT)
-dumping syndrome

17

what causes dumping syndrome

-feeding is too cold
-feeding is too rich
-delivery to intestines is too fast

18

how to prevent complications of feedings

-check residual, do not routine discard
-check mark with inedible ink

19

caring for NG/NI tubes and PEG

-secure tube to nose and gown
-assess site placement and inflammation
-sire care: cleanse peristomal skin and use skin barrier
-rotate guard 360 degrees QD (daily)

20

caring for NG/NI tubes and PEG

-secure tube to nose and gown
-assess site placement and inflammation
-sire care: cleanse peristomal skin and use skin barrier
-rotate guard 360 degrees QD (daily)

21

inserting NG Tubes

-prea assesment
-measure nose to tip of ear lobe to xiphoid
-position 45-90 degrees
-advance tube : watch for coughing and signs of distress
-secure tube and mark with indelible marker

22

Assessing and confirming placement

-apiration: color
-capnometer: measure CO2
-air insertion
measure length of exposed tubing
-assess pH (less than 5.5)
-chest x ray(only initially)

23

caring for NG tube

-abdominal assessment
-monitor gastric output
-asses adeque of suction pressure: no drainage and n/v
-maintina tube patency
-anti reflux valve
-oral hygiene

24

NG irrigation

-positon 30-45 degrees
-instill irrigate slowly
-subtract irritant from NG output
-inject air into vent

25

documentation of NG tube

-type and size of tube
-nare used
-method of placement confirmation
-patient response to care measures
-teaching that was done

26

tubes used for continuous suction

-salem sump tube

27

tubes used for intermittent suction

-salem sump tube
-levine tube

28

suction

-use lowest suction possible
-provide will order intermittent or contious
-pigtail must be above level of stomach

29

intermittent suction order

80mmHg- 100mmHg

30

continuous suction order

60-100mmHg
