It’s 3:00 AM now and you are very tired after an exhausting shift Suddenly a pregnant patient is transferred in to ED by EMTs You evaluate the patient quickly you are shocked, the patient is unresponsive without any respiratory effort
Perspective overall maternal mortality rate: 13.95 deaths per 100 000 maternities 1 Cardiac arrest in pregnancy: 1:20 000 in 2007 1:30 000 in 2002 2 Survival Rate: 6.9% (poorer than others) 3 1 Lewis G, ed.

Critical elements when you face with critically ill pregnant patients You faced with two patient Best hope of fetal survival is maternal survival Pregnancy caused physiologic changes Identify critical patients and try to prevent cardiac arrest
How can we prevent the doom event? Place the patient in the full left-lateral position Give 100% oxygen IV access above the diaphragm Assess for hypotension Consider reversible cause of critical illness
But we can’t prevent cardiac arrest every time So You must start CPR immediately
Start chest compression immediately with high quality 30:2 Place hands slightly higher on the sternum Assess quality with waveform capnography If your try is unsuccessful Place patient in Lt lateral tilt position 27-30 degree
Defibrillation The Facts: It is safe Concern about arcing around external & internal fetal monitors?? There is no evidence But reasonable to remove them Defibrillation dose?? An AED * should be apply as soon as possible * Automated external defibrillator
Do Not Forget!! BLS is cornerstone of ACLS All activities(CAB) should keep on What’s your Idea about ABCD of ACLS??
Airway You faced with an difficult airway, Why?? You should insert an advanced airway Experienced provider
Breathing Ventilation with O 2 100% What is Compression/Ventilation ratio? 100 Compressions/ min / 8-10 breathes/min without synchronization Do avoid hyperventilation plz!!! Continuous pulseoximetry Continuous wave capnography
Circulation Large bore IV lines Drugs?? According to ACLS recommendations Defibrillation? According to ACLS protocol
Decision to C/S Performance?? Facts: The primary importance is mother life Aortocaval compression by gravid uterus?? Fetal viability No ROSC after 4 min of cardiac arrest Despite good BLS & ACLS an correction of reversible causes Unsuccessful chest compression Obvious nonsurvivable mother injury with viable fetus
So this is called Emergency C/S Do not forget continuing BLS & ACLS before and after Emergency C/S
How? Activation of emergency C/S team at the onset of arrest If there is an obvious gravid uterus Emergency C/S may be considered at 4 min: If there is no ROSC Goal: The actual delivery takes no longer 5 min This needs institutional preparation with multidisciplinary approach
