Upper GIT bleeding and GORD Flashcards
Where does most bleeding originate?
85% of GI bleeding happens in the UGIT
Proximal to;the ligament of Treitz.
More than 85% of bleeding stops spontaneously, and are a result of 4 pathologies. What are these pathologies?
Peptic ulcers Oesophageal varices Colonic diverticulosis - Diverticulosis: inflamed pouches in the lining of your intestine Angiodysplasia
Define hematoemesis:
This is a condition in which a patient is found to be vomiting blood.
This could be:
- Digested blood in the stomach (coffee ground emesis = slow bleeding)
- Fresh unaltered blood: (gross blood and clots indicating rapid bleeding)
Define melena:
This is a condition in which faeces are dark and sticky, containing partly digested blood, as a result of internal bleeding. Indicates blood has been in the GI for more than 14 hours.
The more proximal the bleeding site, the more likely melena will occur.
Presentaton:
- black,tarry, semi solid and distinct odor.
Define Hematochezia:
Hematochezia is the passage of fresh blood through the anus, usually in or with stools (contrast with melena)
Hematochezia is commonly associated with lower gastrointestinal bleeding, but may also occur from a brisk upper gastrointestinal bleed.
What are the examination requirements for upper GIT bleeding?
- General examinations and systemic examinations
- Pulse
- Thready pulse - Blood pressure
- Orthostatic hypotension - Signs of shock
- Cold, clammy, cyanotic, tachycardia, hypotension, chest pain, confusion,
How does a nasogastric lavage work in the diagnosis of bleeding UGIT?
A flexible tube is inserted through the nose (goes in via nose to reduce patients likelihood to vomit)
Gastric contents is aspirated and assessed
Used to confirm recent UGITB
- Coffee ground appearance = recent bleeding
- Red blood in the aspirate that doesn’t clear = Active bleeding.
- Lack of blood = Probs isn’t active bleeding but UGITB isn’t excluded
Which 2 lab diagnosis procedures are used in UGITB?
CBC with platelet count
- A complete blood count to asses blood loss
- Should be taken frequently throughout the day
Hemoglobin value, type and crossmatch blood
- Hemoglobin should be checked and crossmatched
- Based on the rate of blood loss
- Hb level should be monitored serially to asses trends.
- Unstable trend could mean ongoing haemorrhage requiring intervention.
What are the 3 priorities of bleeding management?
- Stabilize the patient: protect airway and restore circulation
- Identify the source of bleeding
- Definitive treatment for the cause
What are 4 points of resuscitation and initial management?
- Protect airway and position the patient on the side
- IV access: use 1-2 bore cannula
- Take blood for: Hb, PCV, PT and cross match
- Restore circulation
What are the common causes of UGI bleeding?
Peptic ulcers
Varices
Mallory-Weiss
What are less common causes for UGI bleeding?
Dieulafoy’s lesions Vascular ectasia Watermelon stomach Gastric varices Neoplasia
What are rare causes for UGI bleeding?
Esophageal ulcer Erosive duodenitis Hemobilia Crohn’s disease. Aorta-enteric fistula
What is the single most common cause of bleeding?
Peptic ulcers
What is the cause of peptic ulcers bleeding?
Acid erosion into the submucosal or extraluminal blood vessels
What is the danger of duodenal ulcer formation?
Duodenal ulcers can erode into branches of the gastroduodenal artery.
