Nasogastric and Gastrointestinal
Intubations

A client’s condition may warrant special
interventions to decompress the
gastrointestinal tract. GI intubation is
one of these interventions. Paralytic
ileus is one of the conditions that would
warrant intubation
Paralytic Ileus

Etiology- Cessation of peristalsis resulting from:
– Neurogenic impairment
– Mechanical obstruction
– Direct irritation

Pathophysiology- When peristalsis ceases, the
stomach or small intestine (depending on location of
problem or impairment) becomes distended from
large quantities of air and fluid

Signs and Symptoms- Abdominal distention,
cessation of BMs, absent bowel sounds, vomiting
Purpose and Types of Tubes
Nasogastric Tubes- Primarily inserted
fo decompression of the stomach
 Types of tubes

– Levin
– Salem Sump
– Dobhoff or Duo
Purpose and Types of Tubes

Intestinal Tubes- Long intestinal tubes
serve several purposes:
– Decompression
– Splinting
– Determination of obstruction site

Types of tubes
– Miller-Abbott
– Cantor
Measuring and Inserting an NG
tube
Facilitating Tube Drainage

Because gastric and intestinal fluid must
move against gravity to be removed
suction is required
– Low Suction
– High Suction
– Intermittent Suction
– Constant Suction

Proper functioning
Prevention of Injury
Anchoring the tube
 Pin tube

Prevention of Injury

Prevent Oral Inflammations
– Keep oral membranes moist
– Use of ice chips
– Hard candy

Prevent reflux and/or aspiration
Promotion of Comfort
Removal of excess secretions
 Water soluble lubricant
 Relief for sore throat

– Warm saline gargles
– Ice bag to neck
– Prescribed throat lozenges
– Position changes
Specialty Tube

Sengstaken- Blakemore Tube
– Used to control esophageal varices
– Multi-lumen tube with 2 balloons
