  • SYMPTOMS
    Nausea and vomitting- note the onset, duration and triggers of vomitting in addition to characteristic of vomitus eg/haematemesis (blood in vomit)
    Dyspepsia (indigestion)
    Dysphagia (difficulty swallowing)
    Abdominal pain- note site, onset, nature
    Bowel sounds- present or absent
    Diarrhoea OR Constipation- onset, duration, frequency, characterisitcs of stool eg/melena- black tarry stool resulting from bleeding in upper GI tract

Q

A variety of INVESTIGATIONS may be be necessary to make a diagnosis. Specific examples include:

A
  • x-ray, ultrasound, CT
  • Gastroscopy/Endoscopy- a procedure where a thin, flexibile tube with a light and camera on one end, called an endoscope, is used to look inside the oesophagus, stomach and small intestine (duodenum).
  • Barium Swallow- a test that uses barium swallowed and x-ray to create images of the upper GI tract including throat (pharynx) and oesophagus.
  • Colonoscopy- a procedure where a thin, flexible tube with a light and camera attached is used to look inside your large intestine (colon) and rectum.
  • Laparoscopy- performed under anaesthetic involving a small incision (keyhole) through the abdominal wall to allow the injection of carbon dioxide into the peritoneal cavity to move organs and structures away from each other to be better visualised. It helps in obtaining tissue and fluid samples as well as detecting inflamattion, masses and other abnormalities.

Q

It is not always clear what causes this but people at risk of developing GORD are:

A

Obesity- increased pressure on the stomach can weaken muscles in the oesophagus
smoking, alcohol, coffee or chocolate- these may relax the muscles at the bottom of the oesphagus.
pregnancy- temporary changes in hormone levels and increased pressure on stomach
hiatus hernia- when part of your stomach pushes up through the diaphragm

Q

Causes of gastritis

A

Medications- aspirin, corticosteroids, NSAIDs- these medications inhibit the synthesis of prostaglandins that are protective to the gastric mucosa.

Diet- alcohol, spicy food

Helicobacter pylori infection- prolonged inflammation leads to changes in the stomach and can lead to cancer.

Environmental- radiation, smoking

Pathophysiological conditions- burns, large hiatus hernia, reflux of bile/pancreatic secretions, renal failure, sepsis, shock.

Other factors- endoscopic procedures, NG tube, psychological stress.

Q

Nursing care and management GORD:

A

elevate bed to 30 degrees

patient should not lay supine for 2 - 3 hours after a meal

Medication therapy
- Protein pump inhibitors (PPIs) block the acid secretory pathway eg/omeprazole
- PPIs have a short plasma half-life thereofre the TIMING of administration is important with the greatest efficacy seen when given a meal time.
- PPIs should be given approximately 30 minutes before a meal.
- Long term use of PPIs may increase the risk of falls and fractures.
- PPis are associated with increased risk of C.difficile infection in hospitalised patient’s.

education - avoid late night eating and identified activites that causes reflux for them, weight reduction, avoiding alcohol and smoking

Q

Nursing care and management- GASTRITIS

A

Supportive treatment such as IV fluids and NBM status if vomiting and dehydration accompanies acute gastritis.
Administration of medication therapy- focuses on reducing irritation of the gastric mucosa and providing symptomatic relief eg/ antiemetics, H2 repetor blockers or PPIs to reduce gastric HC1 secretion, antibiotic combinations used to eradicate H.pylori if a cause.
In severe of acute gastritis- NG tube may be used to monitor for bleeding, lavage the precipating agent from the stomach, keep the stomach empty.
Involvement of mulitidisciplanary team- eg/dietician

Q

Nursing care and management PUD

A

Administration of prescribed medication
- PPI’s eg/omeprazole
- H2 blockers eg/rantididine
- Antibiotics eg/amoxicillin, clarithromycin and metroniadole
- Protective medications eg/sucralfate
- Antimetic eg/ Stemetil, ondansetron or metoclopramide to relieve nausea and vomiting.

If complications occur such as haemorrage, performation or pyloric stenosis, intravenous access will need to be established and fluid replacement initiated to correct hypovolemia.

Insertion of a NG tube may be indicated to allow aspiration to decompress and empty the stomach.

Commencement of a fluid balance chart and regular vital signs

A urinary catheter may be required to monitor input/output.

Nutritional therapy- avoid caffeine-containing beverages and foods. Eliminating alcohol as it can delay healing. Avoid foods that cause gastric irritation including hot (spicy) foods, peppper and carbonated beverages.

Gingivitis Signs and symptoms:
Patients with gingivitis present with: Puffy, dusky red, swollen gums Gums which are tender and bleed easily Foul breath Bleeding when brushing teeth Development of pus Formation of abscess with loosening of teeth
26
Gingivitis Risk Factors:
Poor oral hygiene, which leads to the build-up of plaque. If teeth are not cared for properly, plaque hardens into tartar and irritates the gingiva Systemic disorders like diabetes or leukaemia, exposure to heavy metals, pellagra (niacin deficiency) and scurvy (Vitamin C deficiency) Skin disease, particularly erosive lichen planus Hereditary factors Poor or inadequate oral hygiene practices Tobacco use Immune compromise Viral and yeast infections Dry mouth Hormonal changes associated with menses and pregnancy Poor nutrition Substance abuse Ill-fitting dental restoration Type 1 diabetes, leukaemia, Down syndrome, Papillon-Lefevre syndrome and Crohn disease.
27
Gingivitis Treatment:
Prevention through health teaching Dental care Gingival massage Regular dental checkups - including professional cleaning of teeth Treatment of underlying conditions
28
Candidiasis
is an infection caused by a yeast (a type of fungus) called Candida. Candida normally lives on the skin and inside the body, in places such as the mouth, throat, gut, and vagina, without causing any problems. Sometimes, Candida can multiply and cause an infection if the environment inside the mouth, throat, or esophagus changes in a way that encourages fungal growth. Candidiasis in the mouth and throat is also called thrush or oropharyngeal candidiasis. Candidiasis in the esophagus (the tube that connects the throat to the stomach) is called esophageal candidiasis or Candida esophagitis.
29
Oral Candidiasis Signs and Symptoms
White patches on the inner cheeks, tongue, roof of the mouth, and throat Redness or soreness Halitosis Cotton-like feeling in the mouth Loss of taste Pain while eating or swallowing
30
Oral Candidiasis Risk Factors
Taking antibiotics, including inhaled corticosteroids Wearing dentures Having cancer, HIV/AIDS Smoking
31
Oral Candidiasis Treatment
Miconazole oral gel Good oral hygiene Rinising mouth after using inhaled corticosteroids
32
HSV -1
HSV-1 is mainly transmitted by oral-to-oral contact to cause infection in or around the mouth. HSV-1 affects most people on one or more occasions during their lives and is the herpes simplex virus that will be discussed here. Both variants of the herpes simplex virus present with localised blistering.
33
HSV 2
HSV-2 on the other hand is almost exclusively transmitted through genital-to-genital contact during sex. Both variants of the herpes simplex virus present with localised blistering.
34
HSV Cold sores
Herpes simplex is commonly referred to as cold sores or fever blisters, as recurrences are often triggered by a febrile illness, such as a cold.
35
HSV Signs and Symptoms
Lip lesions Mouth lesions Vesicle formation (single or clustered) Shallow painful ulcers Blisters
36
HSV Risk Factors
Upper respiratory infections Excessive exposure to sunlight Food allergies Emotional tension Onset of menstruration
37
HSV Treatment
Topical creams - corticosteroids Mild antiseptic mouthwash Viscous lignocaine Removal or control of predisposing factors Antiviral agents.
38
There are two types of oral cancer:
1) oral cavity cancer- which starts in the mouth 2) oropharyngeal cancer- which starts in the part of the throat behind the mouth. Oral cancer is more common over the age of 40, but is becoming more commonly diagnosied in younger people which is attributed to the human papillomavirus (HPV) which is sexually transmitted.
39
Oral cancer Nursing assessment
Subjective data- health history including recurrent oral herpatic lesions, HPV infection or vaccinitation, syphilis, exposure to sunlight, medications (immunosuppressants), past surgery Functional heatlh patterns- use of alcohol and tobacco, oral hygiene, oral intake, weight loss, mouth or tongue soreness, dysphagia, difficulty speaking. Objective data- ulcer/s on lip, palpable neck mass, limited movement of tongue, increased salivation, drooling, slurred speech, foul breath odour, smear cytology, biopsy, positive toluidine blue test
40
Oral Cancer Nursing management
identify patient's at risk and education of patients eg/smoking cessation Pain management- non pharmacological/pharmacological Provide oral hygiene for patient reasurrance and anxiety management, especially pre and post op surgery
41
The World Health Organisation (2016) defines overweight and obesity as
excessive fat accumulation that presents health risks and arises from a sustained energy imbalance.
42
Nursing care and management Obesity:
Gathering a health history is vital to determing whether any physical conditions are present that may be causing or contributing to obesity eg/family history, previous attempts of weight loss, any underlying conditions such as hypertension, cardiovascular problems, stroke, cancer, diabetes, any medications, previous surgery (eg/bariatric surgery). Calculate a BMI and document on admission form Working within the multidisciplinary team- referal for nutritional therapy, exercise, behaviour modfication, support groups, meciation therapy such as appetite-supressing medications
43
Nursing care and management Malnutrition:
Determine contributing factors eg/ socioeconomoic factors, physical illnesses, incomplete diets, history of eating disorders Calculate a malnutrition score and document on admission Referral to multidiscioplinary team For acute intervention- spcialised nutritional support such as oral supplements, enteral nutrition, parenteral nutrition.
44
Enteral feeding is
a method of supplying nutrients directly into the gastrointestinal tract. Enteral feeding is used for patients who still have a functioning GI tract but for some reason may be unable to take any or enough oral nutrition or it may be unsafe to do so.
45
Parenteral Nutrition is
intravenous feeding, or feeding into your bloodstream. Parenteral nutrition is used for patient who cannot ingest, digest or absorb nutrients via the GI tract.
46
Nasogatric tube (NGT)
This is a thin soft, flexible tube that passess through the nostril and down the back of their throat, through the oesophagus and into the stomach. NGT's can be either fine bore or large bore depending on the need. Fine bore tubes are usually indicated for patient's who require short term enteral feeding, removal or replacement of tube should be considered at the 4 week mark, but will depend on local hospital policy. Large bore tubes, or commonly known as salem sump tubes are double lumen with an air vent, this type of tube is more commonly used in patients who not only require nutritional support but also gastric drainage and aspiration. A salem sump tube should be changes every 10-14 days or as per local hospital policy.
47
Nasojejunal tube (NJT)
Jejunal feeding is the method of feeding directly into the small bowel. The feeding tube is still inserted via the nose but extends into the small bowel via the stomach and pyloric sphincter into the jejunum. This type of tube is used when gastric feeding is poorly tolerated or contraindicated.
48
Percutaneous endoscopic gastrostomy (PEG)
This type of tube is inserted surgically or endoscopically through the abdominal wall into the stomach. PEGs are inserted when a patient has difficulty swallowing (dysphagia) or is unable to obtain adequate nutrition via the mouth. Depending on local hospital policy, a PEG tube can be used after insertion in as little as 4 hours or within 24 hours. A PEG tube only requires to be changed every 12 months.
49
Jejunostomy tube (J-tube)
A jejunostomy tube or J-tube is also a tube that is place through the abdominal wall into the midsection of the small intestine via either a endoscopic or laproscopic procedure. Feeding usually commences within 24-48 hours post placement.
50
Refeeding syndrome
This is a potentially leathal condition that can occur in acutely ill and severly malnourished patients. It occurs when enteral or parenteral nutrition is given too fast. It is characterised by fluid retention and electrolyte imbalances. Electrolyte imblances occur and can cause cardiac, respiratory, hepatic or neuromuscular disorders. Whilst the electrolyte imbalance is able to be corrected, if not identifed it can lead to clinical complications and death. To avoid this, nutritional support is introduced slowly and cautiously with the amount provided titrated upward slowly as the patient tolerates the feed
51
Drug administration Administering medications via tubes can bring its own complications if the medication is not adminstered properly and following the guidelines.
Some medications are not able to be administered via a tube and this is where it is important to be referring to the "Don't Rush to Crush" book for guidance. It is also important to ensure that a pre and post flush with water is provided to avoid occlusions.
52
Aspiration and tube dislodgement are the two most common safety risks when providing nutrition to your patient via a feeding tube. To manage this consider the following
Patient position Aspiration risk Tube position
53
Patient position
correct positions decreases aspiration risk elevate the head of the bed to a minimum of 30 degrees, preferable is 45 degrees. if you need to perform a procedure, stop the feed, lower the bed and then return the bed to the position before recommencing the feed. if patient is on intermittent feeds, remain upright for 30-60 minutes post feed. Always check local policy and procedure.
54
Aspiration risk
prior to using the tube for either feeding or medication administration, proper tube positions should always be checked. aspirate tube to check for position, you should see gastric contents.
55
Tube position
on insertion, an x-ray needs to be completed to confirm placement. (GOLD STANDARD!) aspiratate as above, and use a pH strip to confirm placement. recheck length of tube, at each shift change, pre and post using the tube
