3 IntroductionGastrointestinal intubation is inserting of rubber or plastic tube into the stomach , duodenum or intestinalThe tube inserted through mouth .nose , or abdominal ( gastrostomy .jejunostomy )The tube short , medium , long
4 Types of Tubes Short- Nasogastric tube Introduced from the nose to the stomachLevin and Gastric (Salem) SumpUsed to remove gas and fluid from the upper GI tract or to obtain a specimen of gastric contentsSometimes used for medications or feedings ( gavage )
5 Levin Tube Single Lumen (hollow part of tube) Size 14-18 French Made of plastic or rubber with opening near tipIt is 125 cm longCircular markings on the tube serve as insertion guides
6 Gastric (Salem) Sump Gastric sump tube ( salem. Ventrole) Double lumen catheter .clear plasticPlastic, FR.It is 120 cm longUsed to decompress thestomach, keeps it empty
7 Smaller, inner tube (blue pigtail) vents the larger suction-drainage tube to the atmosphere by way of an opening at the distal end of the tube.Keeps the suction force at the drainage openings at less that 25 mm Hg to prevent capillary irritation.Connected to low continuous suction.Vent lumen kept above the client’s waist.
9 Medium tubes.Medium length- nasoenteric used for feeding. Example- DobhoffPlaced in the duodenum or jejunum by fluoroscopy (x-ray dept) or at client’s bedside.Verified by x-ray before feedingsbegin. May take up to 24 hrs.to pass through the stomachinto the intestines.Place client on right sideto facilitate passage
10 Long- nasoenteric tubes. Long- nasoenteric tubes introduced through the nose and passed through the esophagus and stomach into the intestinal tract.Used to aspirate intestinal contents-ie. gas and fluidUsed to (Decompression) to prevent intestinal obstruction.Due to peristalsis, prevents vomiting, reduces tension at the incision line and prevents obstruction.
11 Long- nasoenteric tubes. Examples of long tubes:Miller- Abbott-is double lumen ( fr ) 300 cm rubber tubeone lumen used for aspiration and other for Introduce with mercury, water, or saline
12 Long- nasoenteric tubes Harris-Is single lumen ( 14 fr )used for suction and irrigationmercury-weighted of about 180 cmThis tube metal tip that lubricateThis use for irrigation & suction .
13 Long- nasoenteric tubes Cantor tube –has a large balloon at distal end of tube. Filled with4- 5 ml of mercury, water or saline to weight the tubeIt is 300 cm long
15 Tube inserted through the nose into stomach DefinitionTube inserted through the nose into stomach
16 Purposes:To administer tube feedings and medications to clients unable to eat by mouth or swallow a sufficient diet without aspirating food or fluids into the lungsTo establish a means for suctioning stomach contents to prevent gastric distention ,nausea, and vomiting.To remove stomach contents for laboratory analysisTo lavage(wash)the stomach in case of poisoning or overdose of medications.
17 Purposes To drain fluid or air from the stomach. To promote healing after bowel surgery.To monitor bleeding in the gastrointestinal (GI) tract.To help treat an intestinal obstruction.
18 Assessment & Preparations: Assessment & Prepare the clientPresence of gag reflexMental status or ability to cooperate with procedureCheck physician's order for insertion of NG tube.Explain procedure to patient.Assist the patient to high Fowler's position.Drape chest with disposable pad
19 Assess the client nares Ask client to hyperextend the head & using flashlightObserve ( intactness of tissue nostrils including any irritation or abrasion )Examine the patient’s nostril for septal deviation. To determine which nostril is more patent, ask the patient to occlude each nostril and breathe through the otherPatency of nares & intactness of nasal tissue ( note especially history of nasal surgery or deviated septum )
20 Assess & prepare the tube If rubber tube :used placed it on ice for 5 to 10 minutesThis stiffens the tube , facilitating insertionIf plastic tubeUsed place it in warm water until tube softer & more flexibility , facilitating insertion
21 Equipments: Nasogastric tube Adult - 16-18F Viscous lidocaine 2% Oral analgesic spray (Benzocaine spray or other)Oral syringe, 12 mLGlass of water with a strawWater-based lubricant
22 Equipments: Non allergenic adhesive Tape 2,5 cm wide Emesis basin or plastic bagWall suction, set to low intermittent suctionSuction tubing and containerFlashlight .Stethoscope.Toomey syringe (20 to 50 ml) .TissuesDisposable pad & gloves . .Tongue blade .Normal saline solution (for irrigation only).
25 NoteA nasogastric (NG) tube is used for the procedure. The placement of an NG tube can be uncomfortable for the patient if the patient is not adequately prepared with anesthesia to the nasal passages and specific instructions on how to cooperate with the operator during the procedure
26 Determine how far to insert the tube Measure the distance to insert tube by placing tip of tube at client's nostril and extending to tip of ear lobe and then to tip of xiphoid process.Mark tube with piece of tape.
27 Nasogastric tube lubrication with water-based lubricant.
28 Estimation of nasogastric tube length from nostril to stomach
29 Insert the tube Prepare equipment. Wash hands. Wear disposable gloves. Instill 10 mL of viscous lidocaine 2% (for oral use) down the more patent nostril with the head tilted backwards, and ask the patient to sniff and swallow to anesthetizeLubricate tip of tube with water soluble lubricant.Ask client to lift head, and insert tube into nostril while directing tube upward and backward.
30 Aspiration of viscous lidocaine into an oral syringe
32 Cont,,If client gag when tube reaches pharynx, provide tissues for tearing or watering of eyes.When pharynx is reached, instruct client to touch chin to chest.Encourage client to sip water through a straw or swallow even if no fluids are permitted.
33 Patient flexing his neck and drinking water while a nasogastric tube is inserted.
34 Advance tube in downward and backward direction when client swallows. Stop when client breathes.If gagging and coughing persist, check placement of tube with tongue blade and flash light.Keep advancing tube until tape marking is reached.Do not use force, rotate tube if it meets resistance.Discontinue procedure and remove tube if there are signs of distress, such as gasping, coughing, cyanosis, and inability to speak or hum.
35 Confirming PlacementTube placement is confirmed prior to any use of the tube for suction, irrigation, medication admin. or feedings.Initially, an x-ray should be ordered to confirm placement of weighted feeding tubes (Dobhoff).Verify NG or Salem Sump tubes by auscultation of an injected air bolus over the epigastrium or aspirate stomach contents.Measurement of tube length, visual inspection and measuring of the aspirate pH is also recommended.
38 Securing the GI tube Use a skin barrier to prep the skin Use NG strip or place a piece of tape under the tube at the nose and secure to the skin, place another piece of tape over the first piece.Secure tube to client’s gown with a safety pin.

74 Definition of Parenteral Nutrition The administration of complete and balanced nutrition by intravenous infusion in order to support anabolism, body weight maintenance or gain, and nitrogen balance, when oral or enteral nutrition are not feasible or are inadequate
75 Indications for TPNMall absorption syndromes, such as short bowel syndromeConditions requiring complete bowel rest for prolonged periodsPre and post-operative support in patients with pre-existing malnutrition, in who GI function is impairedMalignancy undergoing treatment, surgery, radiation, chemo who are unable to obtain adequate nutrition by an enteral route
76 TPN is generally NOT indicated… When an inpatient has a functioning GI tractTPN therapy is expected to be less than 5 daysPrognosis does not warrant aggressive nutrition support
