Subtotal Gastrectomy Nursing Care Plan
Partial stomach resection with dumping-syndrome prevention and B12/iron follow-up.
Quick answer
A Subtotal Gastrectomy nursing care plan centers on protect the anastomosis and monitor for bleeding or leak; manage the nasogastric tube safely; prevent and treat dumping syndrome. Priority nursing diagnoses are Imbalanced nutrition, Acute pain, Diarrhea. The plan below gives assessment cues, measurable goals, 3 intervention sets with rationales, and patient teaching.
Overview
Subtotal (partial) gastrectomy removes a portion of the stomach, with the remnant anastomosed to the duodenum (Billroth I) or jejunum (Billroth II), for gastric cancer or intractable peptic ulcer disease.
A smaller reservoir and loss of pyloric control produce dumping syndrome: hypertonic chyme rushes into the small bowel, drawing fluid into the lumen and causing early cramping, diarrhea, palpitations and diaphoresis, then a later reactive hypoglycemia one to three hours after eating. Loss of intrinsic factor and reduced acid also impair vitamin B12, iron, calcium and folate absorption.
Nursing care focuses on anastomotic protection, nasogastric tube management, a small-frequent low-carbohydrate dry-meal pattern, and lifelong nutritional monitoring.
Key numbers to know
NG tube
Do not irrigate or reposition an NG tube after gastric surgery without a surgeon's order — it can disrupt the suture line.
Expected drainage
Bright red for the first few hours, then darkening to brown-green; persistent bright red bleeding is abnormal.
Dumping diet
Small, frequent, high-protein, moderate-fat, low simple-carbohydrate meals; fluids between rather than with meals.
B12
Lifelong vitamin B12 supplementation is usually needed to prevent pernicious anemia.
Nursing priorities
- Protect the anastomosis and monitor for bleeding or leak.
- Manage the nasogastric tube safely.
- Prevent and treat dumping syndrome.
- Maintain nutrition, weight and micronutrient levels.
- Control pain and prevent pulmonary complications.
Nursing assessment
Subjective data
- Reports of epigastric pain, fullness or nausea
- Reports of cramping, dizziness or palpitations after meals
- Complaints of weakness or sweating one to three hours after eating
- Reports of unintentional weight loss
Objective data
- Nasogastric output volume and color
- Vital signs and hemoglobin for bleeding
- Abdominal distention, bowel sounds, incision appearance
- Weight trend, albumin, B12, iron, folate and calcium levels
- Postprandial tachycardia, diaphoresis or hypoglycemia on glucose check
Related factors
- Reduced gastric reservoir and loss of pyloric sphincter control
- Rapid gastric emptying of hyperosmolar contents
- Decreased intrinsic factor and gastric acid
- Surgical incision and anastomosis
Key nursing diagnoses
Goals and expected outcomes
- The client will remain free of anastomotic leak and significant bleeding.
- The client will tolerate prescribed meals without dumping symptoms.
- The client will stabilize weight and maintain normal nutritional labs.
- The client will describe the post-gastrectomy diet plan accurately.
Nursing interventions and rationales
Early postoperative care
- Maintain NG suction as ordered; never reposition or irrigate without an order.
- Record drainage; report bright red bleeding, sudden cessation of output or severe distention.
- Monitor vital signs, temperature and incision for signs of leak or peritonitis.
- Provide analgesia, incentive spirometry and early ambulation.
Dumping syndrome management
- Serve six small dry meals daily; withhold fluids for 30 minutes before and after eating.
- Emphasize protein and complex carbohydrates; limit simple sugars.
- Have the patient lie down or recline for 20–30 minutes after meals to slow emptying.
- Check glucose if late symptoms occur and treat reactive hypoglycemia.
Long-term nutrition
- Weigh regularly and track intake with dietitian involvement.
- Administer or teach lifelong vitamin B12 injections or high-dose oral supplementation.
- Monitor for iron-deficiency anemia, osteoporosis and calcium deficiency.
- Encourage chewing thoroughly and eating slowly.
Patient and family teaching
- Explain what dumping syndrome is and how meal composition prevents it.
- Review the requirement for lifelong B12 replacement.
- Report black stools, vomiting blood, fever or severe abdominal pain.
- Keep nutrition follow-up and periodic lab appointments.
How to build this plan
- 1Assess the patient. Collect subjective and objective data through interview, physical assessment, labs and chart review. Complete, accurate data is the foundation of every later step.
- 2Analyze and cluster the data. Group related cues, compare them with normal findings, and identify patterns that point to actual or potential problems.
- 3Formulate nursing diagnoses. Write the problem statement using a recognized diagnostic label plus related factors and evidence (problem related to cause as evidenced by signs).
- 4Set priorities. Rank diagnoses as high, medium or low using ABCs, Maslow's hierarchy and the patient's own stated priorities. Life-threatening problems come first.
- 5Establish goals and outcomes. Write SMART, patient-centered outcomes: specific, measurable, attainable, realistic and time-bound (short-term and long-term).
- 6Select nursing interventions. Choose independent, dependent and collaborative actions that are safe, evidence-based and matched to the outcome.
- 7Provide rationales. State the scientific reason each intervention works. Rationales are what turn a task list into clinical reasoning.
- 8Evaluate the plan. Compare the patient's actual response with the expected outcome: met, partially met or not met — then continue, revise or discontinue.
- 9Document and communicate. Record the plan and the patient's response in the health record so the whole team works from the same information.
