Imagine this scenario. A patient is seated in your chair, and you ask about their medical history: “Do you have any chronic illnesses?” They respond, “No, thank God, everything’s perfectly fine.” You begin your work, but then you start noticing a few subtle, unusual signs—a slight yellowish tint in the whites of their eyes, or perhaps a mild swelling in their legs.
Sadly, this scenario isn’t far from reality. Some patients with liver diseases might feel apprehensive about disclosing their condition, often fearing that we might refuse to treat them. This behavior, usually stemming from a lack of awareness, unfortunately places both the patient and themselves at significant risk.
The liver isn’t just another organ in the body. It’s the body’s primary “chemical factory,” responsible for almost everything, from metabolizing the medications we prescribe to manufacturing the crucial proteins that stop bleeding. Any dysfunction in this vital organ can throw the body’s entire balance into disarray.
In this article, we’ll provide you with a clear, straightforward protocol on how to manage liver patients in your clinic. We’ll cover everything, from the moment you first suspect their condition to safely choosing medications and performing extractions without any complications.
Before Anything Else: Ethics and Patient Education
Our foremost duty as healthcare professionals is to treat patients, not to reject them. Refusing treatment to a patient simply because they have a liver disease is both unethical and illegal. Our role is to thoroughly understand their condition and implement the necessary precautions to provide safe and appropriate care.
We absolutely must educate our patients about the critical importance of honesty in their medical history. It’s also vital to reassure them that our goal isn’t to turn them away, but rather to ensure their safety.
The Bottom Line: A liver patient has every right to receive care, just like any other patient. Your role is to understand how to treat them correctly and safely.
How to Spot a Liver Patient Who Might Be Hiding Their Condition (Clinical Signs and Symptoms)
Sometimes, an experienced clinician’s eye can pick up on subtle signs that raise suspicion of a liver problem, even if the patient denies it. Always stay alert for these indicators:
-
Jaundice: This is arguably the most common symptom. You’ll notice a distinct yellowing in the Sclera (whites of the eyes), and potentially even in the Skin or Palate (roof of the mouth).
-
Ascites: A noticeable swelling in the Abdomen due to fluid accumulation.
-
Peripheral Edema: Swelling in the legs or ankles, also due to fluid retention. This occurs because of a deficiency in Albumin, a protein primarily produced by the liver.
-
Other Signs: Patients might complain of Abdominal Pain, or you might observe “spider angiomas” on the skin, or Palmar erythema (redness in the palms of the hands).
If you detect any of these signs, it’s crucial to gently re-question the patient. Explain the importance of knowing their health status for their own safety.
The Three Major Challenges in Treating Liver Patients
When you’re managing a patient with liver disease, there are three fundamental challenges you must always keep in mind:
-
Drug Metabolism
-
Bleeding Risk
-
Cross-Infection
Let’s tackle each challenge individually and see how to effectively manage them.
Challenge One: Safe Drug Prescription
The golden rule here is straightforward: Steer clear of any Hepatically Metabolized Drugs (medications primarily processed by the liver) and instead opt for Renally Excreted Drugs (medications eliminated via the kidneys).
Local Anesthesia
Theoretically Best: An “ester” type anesthetic, like Procaine, because it’s metabolized in blood plasma, not the liver. Unfortunately, this type is almost obsolete due to its high incidence of allergic reactions.
The Practical and Safe Solution: Lidocaine or Mepivacaine are considered safe if used at the lowest effective dose possible (1). Why? Because they are metabolized in the liver, meaning if the liver is compromised, their effect will last longer, and their blood concentration could potentially increase. The maximum dose must be significantly reduced from the normal recommended levels.
Analgesics
Strictly Forbidden: Any Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) such as Ibuprofen, Diclofenac, or Ketorolac. These medications not only pose a risk to the liver but also dramatically increase the risk of gastric bleeding and blood thinning.
The Safest Choice: Paracetamol, but only at carefully calculated doses not exceeding 2 grams per day for a liver patient. There’s a product available called Hepamol, which combines Paracetamol with Methionine, a substance known to protect the liver, making it a very good option.
Antibiotics
The Best and Safest: The Penicillin family, such as Amoxicillin, because they are primarily eliminated via the kidneys.
Must Be Avoided: Tetracycline, Clindamycin, and Azithromycin are largely metabolized by the liver and can be toxic to it (2).
Challenge Two: Bleeding Management
A liver patient bleeds easily. Never underestimate a simple extraction, thinking “it’s just a routine pull.”
Before Any Surgical Procedure: You absolutely must request recent blood tests or, at the very least, obtain a written Physician Consultation. The essential tests include:
-
Platelet Count
-
Prothrombin Time (PT) and International Normalized Ratio (INR)
-
Partial Thromboplastin Time (PTT)
-
Bleeding Time
If these values are abnormal, the patient must return to their physician for stabilization before you proceed with any work. They might require platelet or plasma transfusions.
During and After Extraction: Employ every available Local Hemostatic Measure. Apply firm pressure with gauze, use materials like Gelfoam or Surgicel inside the socket, and meticulously Suture the socket.
Challenge Three: Cross-Infection Control
Many liver patients are carriers of Hepatitis B Virus (HBV) or Hepatitis C Virus (HCV). You must treat every liver patient as a “potential source of infection” to protect yourself, your team, and your other patients.
Scheduling Appointments: It’s best to schedule known liver patients for the end of the day. This allows you ample time for thorough disinfection of the clinic afterward.
Personal Protection:
-
Wear double gloves and a double mask.
-
In cases of HBV, you must wear a Face Shield or Eye Goggles, as this virus can also spread through aerosols.
-
In cases of HCV, the greater risk comes from direct blood contact. Therefore, exercise extreme caution when handling needles and sharp instruments.
If a Needle Stick Injury Occurs:
-
From an HCV patient: Thoroughly wash and disinfect the wound. Conduct an HCV test for the patient, and have yourself tested, repeating the test after 3 weeks, then 6 months.
-
From an HBV patient: If you are unvaccinated or your vaccination is not effective, you must receive Anti-HBV Immunoglobulin within 48 hours, and you might need to start your vaccination doses (3).
Impression Disinfection: It’s critically important to inform your dental lab technician about the patient’s condition so they can also take necessary precautions.
Special Case: The Liver Transplant Patient
First 3 Months Post-Transplant: Avoid any surgical procedures unless in extreme emergencies, and only after consulting with the patient’s physician. If you absolutely must proceed, the patient will require Antibiotic Prophylaxis.
After 3 Months: You can generally treat them more routinely, but always remember that these patients are typically on immunosuppressant medications. This makes them more susceptible to infection and can impair wound healing.
Conclusion: Caution is Paramount
Managing a liver patient demands that you be an “observant,” “cautious,” and “cooperative” clinician. Observant to catch the subtle signs, cautious in your choice of medications and procedures, and cooperative with the patient’s primary physician. By meticulously following this clear protocol, you can provide liver patients with safe and excellent dental care, while simultaneously protecting yourself and your team.
