Hemostatics and Emergency Drugs in the Dental Office Guide

Every extraction bleeds, and most bleeding stops with pressure — but not all. Hemostatics are the drugs and materials used when a clot will not form or keeps breaking down: after surgical extractions, in patients on blood thinners, or when oozing persists despite a pressure pack. Separately, every dental office must be ready for medical emergencies — fainting is commonest, but anaphylaxis, asthma, hypoglycemia, chest pain and seizures all occur in the dental chair.

Preparedness is both an ethical duty and, in most countries, a legal one: the dentist must manage the emergency until professional help arrives. That means two things on the shelf before anything goes wrong — hemostatic materials for bleeding, and a stocked, in-date emergency drug kit every staff member knows how to use.

Key Concepts

• Local hemostatics: oxidized cellulose and gelatin sponge (a clot scaffold in the socket), ferric sulfate 15.5% for gum oozing, and tranexamic acid 4.8% mouthwash — 10 mL rinsed 2 minutes, four times daily.
• Adrenaline 1:1000 (1 mg/mL): the single most important emergency drug — definitive treatment for anaphylaxis.
• Emergency kit essentials: adrenaline ampoules, antihistamine (chlorphenamine), hydrocortisone, salbutamol inhaler, glyceryl trinitrate (GTN) spray, aspirin 300 mg, glucose, buccal midazolam, and oxygen.
• Syncope (faint): the commonest dental emergency — managed by laying the patient flat with legs raised and giving oxygen, not by drugs.

How It Works

Bleeding stops when platelets plug the vessel and fibrin locks the plug into a clot; later the enzyme plasmin dissolves it. Tranexamic acid blocks plasmin, so fragile clots survive — ideal for warfarin patients. Adrenaline fights anaphylaxis two ways: alpha action squeezes vessels and raises blood pressure, beta action opens airways and strengthens the heartbeat. GTN dilates coronaries in angina; glucose reverses hypoglycemia.

1. For socket bleeding: a damp gauze pressure pack with firm biting for 30 minutes comes before any drugs.
2. If oozing continues: place oxidized cellulose or gelatin sponge in the socket, or try tranexamic acid rinse.
3. For suspected anaphylaxis (rash plus breathing difficulty or collapse): adrenaline intramuscularly at once — never wait.
4. Call emergency services, keep the patient supine with legs raised unless breathing is difficult, and give oxygen.

Worked Example

An adult develops anaphylaxis minutes after a penicillin injection: widespread hives, wheeze and falling blood pressure. Adrenaline 1:1000 contains 1 mg per mL, and the adult dose is 0.5 mg intramuscularly:

1. Draw up 0.5 mL of adrenaline 1:1000 (0.5 mL × 1 mg/mL = 0.5 mg).
2. Inject into the outer mid-thigh, which absorbs fastest.
3. Reassess after 5 minutes; if there is no improvement, repeat the 0.5 mg dose while awaiting the ambulance — and never give it intravenously in the dental office.

Common Misconceptions

• "Any bleeding needs stitches." Most post-extraction bleeding stops with firm pressure; sutures close wounds but don't stop all oozing — hemostatic materials handle the rest.
• "Patients on aspirin must stop it before extraction." For most routine extractions aspirin — and even warfarin with INR checked — is continued, because the clotting risk of stopping exceeds the bleeding risk; local measures manage the socket.
• "Emergencies never happen in a dental office." Syncope is common, especially in anxious or fasting patients — which is exactly why drills and an in-date kit are mandatory.

Real-World Applications

• Surgical wisdom-tooth removal, where bone bleeding and oozing are routine.
• Extractions in anticoagulated patients: INR checks plus tranexamic acid mouthwash.
• Patients with hemophilia or von Willebrand disease, treated with hematologist-agreed factor cover plus local hemostatics.

Bleeding and emergencies are rare but unforgiving. Stock the right materials, know the doses by heart, drill the team: pressure first, hemostatics second, adrenaline without delay.
