MEDICAL EMERGENCIES IN THE DENTAL OFFICE: HOW TO AVOID A BAD DAY Dr.Aditi Singh P.G. 1st year Dept. Of Preventive & Pediatric Dentistry SDCH,Rishikesh

REALITY BITES!! YOU KNOW THAT YOU ARE NOT HAVING A GOOD DAY WHEN:

CASE # 1  A 62 y/o anxious female needs extraction of four erupted teeth. Her past medical history is positive for Type II diabetes and a history of seizures many years ago.You inject her with mandibular block. After five minutes you are summoned to the operatory by your assistant. The patient is unconscious. What could be happening and what do you do?

THE “ARJUN - DURYODHAN” PHILOSOPHY
