Medical emergencies during dental procedures test rapid recognition and management skills, forming a recurring high-yield segment in UPPSC Dental Surgeon exams with scenario-based MCQs.

Why This Topic Dominates UPPSC

UPPSC emphasizes chairside emergencies over rare syndromes, mirroring real-world BPHU practice where quick ABC stabilization saves lives. Expect 6-8 questions on protocols, drug dosages, and prevention—prioritize over complex surgeries.

Core Emergencies and Protocols

• Syncope (Vasovagal): Most common; patient pale, sweaty. Position Trendelenburg (legs up), airway open, ammonia inhalant, monitor vitals.
• Asthma Attack: Wheezing, dyspnea. Stop procedure, salbutamol inhaler (2 puffs), oxygen; severe cases get epinephrine 0.3mg IM.
• Anaphylaxis: Urticaria, hypotension post-LA. Epinephrine 1:1000 (0.3-0.5mg IM every 5 min), antihistamine, steroids; call 108.

Cardiovascular and Metabolic Crises

Neurological and Respiratory Must-Knows

• Epilepsy: Protect airway, midazolam 10mg buccal/IN; diazepam 10mg IV if prolonged.
• LA toxicity: CNS excitation first (tinnitus, seizures), then depression—supportive care, benzodiazepines, lipid emulsion 1.5ml/kg for bupivacaine.
• Foreign body aspiration: Heimlich, back blows; bronchoscopy referral.

UPPSC 2026 Predicted “Tricky” Question

Q: A patient starts having a seizure while in the dental chair during an extraction. What is the most
important first step?

• A) Force a mouth prop between the teeth.
• B) Give IM Midazolam immediately.
• C) Clear the area and lower the chair to a supine position.
• D) Restrain the patient’s arms.

Correct Answer: C. In the screening test, always look for the most conservative/safe initial step. You never put anything in the mouth during a seizure or restrain the patient
