Esophageal Varices nursing care: what to assess and what to do first
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Esophageal varices are dilated, fragile veins in the lower oesophagus caused by portal hypertension, usually from cirrhosis. A bleed is an airway emergency before it is a volume one, because haematemesis brings aspiration risk alongside blood loss. Nursing priority is airway and oxygenation first, then large-bore IV access, blood products, and vasoactive drugs to lower portal pressure.
Recognising it at the bedside
Varices themselves are silent until they bleed, so recognition starts with risk assessment: any patient with known cirrhosis, chronic hepatitis, or a history of alcohol use disorder carries risk of portal hypertension and should be assessed for stigmata of liver disease on admission, not just when a GI complaint arises. Spider angiomata, caput medusae, splenomegaly, and ascites all point toward portal hypertension severe enough to have formed varices.
When bleeding occurs, the presentation is usually dramatic and sudden: haematemesis of bright red or coffee-ground blood, melena, and rapid haemodynamic deterioration. Unlike a slow peptic ulcer ooze, variceal bleeds can lose a large volume in minutes because the vessels are under portal pressure rather than arterial pressure alone, and a patient can go from talking to shocked faster than staff expect.
Why the classic presentation misleads
Teaching often frames GI bleeding as primarily a fluid and haemodynamic problem, which leads staff to focus first on IV access and vital signs. With varices, the airway is compromised before or alongside the volume loss: active haematemesis in a patient who may already have altered mentation from hepatic encephalopathy creates a high aspiration risk, and a variceal bleed can fill the airway with blood faster than suction can clear it.
No straining, no coughing, nothing that raises portal pressure is the principle that should shape every action around this patient, from repositioning to bowel care to how you manage a gag during NG tube insertion. Valsalva manoeuvres, vomiting against a closed glottis, and even vigorous coughing spike portal pressure and can convert a controlled situation into a torrential bleed, which is why airway management and sedation planning have to account for this risk specifically, not just generic bleed protocols.
Priority nursing actions
Airway first: position the patient to protect against aspiration, have suction at the bedside and functioning before anything else, and anticipate early intubation in active haematemesis, particularly if mentation is impaired. Only once airway is secured or being actively managed do you move to two large-bore IVs, type and crossmatch, and fluid or blood product resuscitation guided by haemoglobin trends rather than a fixed volume target, since overtransfusion can itself raise portal pressure and provoke rebleeding.
Administer vasoactive medication as ordered, typically octreotid or a similar somatostatin analogue, to reduce splanchnic blood flow and portal pressure while endoscopy is arranged. Keep the patient absolutely NPO, avoid inserting an NG tube unless specifically ordered for the reason above, and minimise any activity that provokes straining or coughing. Prepare for emergency endoscopic banding or sclerotherapy, and know that balloon tamponade remains a bridge option only when endoscopy is not immediately available, given its own risk of airway compromise and oesophageal injury.
Labs and diagnostics to expect
Expect a full haemodynamic and coagulation picture: haemoglobin and haematocrit trended serially rather than as a single value, platelet count, PT/INR, and fibrinogen, since cirrhotic patients frequently have coagulopathy that compounds the bleed. Liver function tests and albumin help characterise the underlying disease severity, and a basic metabolic panel tracks renal function, which can deteriorate quickly with hypoperfusion.
Upper endoscopy is both diagnostic and therapeutic and is the definitive test, usually performed urgently once the patient is stabilised enough to tolerate it. Blood type and crossmatch should be sent immediately on suspicion of a variceal bleed rather than waiting for confirmation, given how fast transfusion needs can escalate.
Complications and their early signs
Hypovolaemic shock is the most immediate threat: watch for tachycardia, hypotension, narrowing pulse pressure, and cool clammy skin, which can appear before a dramatic drop in haemoglobin shows up on labs. Rebleeding is common in the days after the index bleed, so continued vigilance for fresh haematemesis or melena does not stop once the first bleed is controlled.
Aspiration pneumonia is a direct consequence of the airway risk discussed above and should be suspected with new fever, hypoxia, or crackles in the days following a bleed. Hepatic encephalopathy frequently worsens after a variceal bleed because blood in the GI tract is a large protein load that raises ammonia production, so reassess mentation and asterixis closely in the recovery period, not only during the acute event.
Teaching that changes outcomes
Teach the patient and family to avoid anything that raises intra-abdominal or portal pressure: heavy lifting, straining at stool, and vigorous coughing all carry real risk, so managing constipation proactively with stool softeners is part of variceal prevention, not an afterthought. Alcohol cessation is the single teaching point with the greatest effect on disease progression for patients whose cirrhosis is alcohol-related, and it should be framed without judgement and paired with concrete referral to cessation support.
Explain the purpose of any prescribed non-selective beta-blocker, such as propranolol or nadolol, as reducing portal pressure to prevent a first or repeat bleed, and stress that missed doses undermine that protection even when the patient feels well. Patients should know the warning signs of a bleed, black tarry stools or vomiting blood, and be told to seek emergency care immediately rather than waiting to see if it resolves, since a variceal bleed can progress from minor to life-threatening within an hour.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our gastrointestinal practice questions are the closest set to what this page covers.
Common questions
Why is a variceal bleed considered an airway emergency?
Active haematemesis, often in a patient whose mentation is already impaired by hepatic encephalopathy, creates a high risk of aspiration that can compromise the airway faster than blood loss compromises circulation. Airway protection and suction readiness take priority over IV access and fluids in the initial response.
Why avoid an NG tube in suspected variceal bleeding?
Blind NG insertion can traumatise a fragile, dilated varix and provoke or worsen bleeding, and the gagging it triggers raises portal pressure at the worst possible moment. It is used only when specifically ordered, and typically not as a routine part of GI bleed workup in this population.
What does a nonselective beta-blocker do for esophageal varices?
Drugs such as propranolol or nadolol reduce cardiac output and cause splanchnic vasoconstriction, lowering the pressure within the portal system and the varices themselves. Taken consistently, they reduce the risk of a first bleed and of rebleeding after an initial episode.
Why does a GI bleed worsen hepatic encephalopathy?
Blood in the gastrointestinal tract is broken down by bacteria into ammonia, adding a large protein-like nitrogen load that the already impaired liver cannot clear. Nurses should watch for new or worsening confusion and asterixis in the days following a variceal bleed, not only during the acute event.
What activity should patients with known varices avoid?
Anything that raises portal pressure suddenly: straining at stool, heavy lifting, vigorous coughing, and repeated vomiting. Managing constipation proactively and treating chronic cough are practical, low-cost ways to reduce bleed risk.
