What is a gastrointestinal (GI) bleed?
A gastrointestinal (GI) bleed refers to bleeding in the digestive tract, which includes the esophagus, stomach, small intestine, or large intestine. It may present as upper gastrointestinal bleeding (esophagus, stomach, or duodenum) or lower gastrointestinal bleeding (colon or rectum). Bleeding can be overt, with visible bright red blood in vomit or stool, or occult, marked by symptoms like lightheadedness, abdominal pain, and fainting.
Causes and risk factors
Common causes of GI bleeding include peptic ulcer disease, inflammatory bowel disease (such as Crohn's disease or ulcerative colitis), diverticulosis, tumors, or vascular malformations. Risk factors include:
- Use of nonsteroidal anti-inflammatory drugs (NSAIDs) or blood thinners.
- Alcoholism leading to gastritis, ulcers, or liver disease.
- Older age, especially in individuals with comorbidities.
- Men are at higher risk due to conditions like diverticulosis and vascular disorders.
Symptoms of GI bleed
Symptoms range from mild to severe and may include:
- Fatigue, pallor, or abdominal pain.
- Vomiting blood (hematemesis) or passing black, tarry stools (melena).
- Signs of shock, such as low blood pressure and rapid heart rate, in severe cases.
Nursing diagnosis and interventions
Nurses play a critical role in diagnosing and addressing the condition through thorough assessment, prompt interventions, and continuous monitoring.
- Assessment: Nurses monitor vital signs, such as blood pressure and heart rate, to identify signs of shock. Evaluate stool and vomit for bright red blood or melena. Track laboratory values like platelet count and hemoglobin to assess the severity of the bleeding risk.
- Nursing interventions: Administer prescribed medications, ensure IV fluid replacement, and prepare the patient for procedures like endoscopy.
- Evaluation: Advice on lifestyle changes, including avoiding nonsteroidal anti-inflammatory drugs, alcohol, and smoking, to reduce recurrence.
