Guest post by Greg Press   The second perimortem C-section of my career happened last week. The first was almost ten years ago. While I’m hardly an expert (takes three to be an expert), I have some pointers worth sharing. The first case happened on the first day of my first job, in Houston, having just completed my ultrasound fellowship in New York. The night started with a guy shot in the right chest: intubation and chest tube. His girlfriend was brought in next, pregnant, shot in the head: perimortem c-section and neonatal intubation. The second was just the other day. It was my first code at my new job at a small hospital in Wellington, New Zealand. A young girl hanged herself, was found by family who called EMS. They found in her VFib, defibrillated, started CPR, intubated and called to warn us of her arrival. They reported she was in asystole, a bad sign for mom. They reported she was 22 weeks pregnant, a bad sign for baby. There have been a few PMCS reviews circulating recently in the EM world and I agree with most of their recommendations. But I have differing thoughts on a few points. Do not memorize the number 24. Or 23. Or 25, or whatever the gestational age your neonatologists say they can currently save premies. You are unlikely to know the precise age–the mother is generally the most reliable source for this information, but generally not in this circumstance. We understood the hanged woman to be 22-weeks…

Drugs don't work in cardiac arrest

confirming what we all know to be true: epinephrine in cardiac arrest only keeps earthworms up at night. in patients with an unshockable rhythm, perform quality chest compressions and secure the airway while you search for/empirically treat for the cause of the arrest. http://emupdates.com/?p=4170

Knee height for chest compressions

Compressions should be done with bed at the level of the knees of the person doing chest compressions. Emerg Med J. 2009 Nov;26(11):807-10.

The resuscitation of a patient who is in cardiac arrest of unknown etiology in PEA or asystole proceeds with the simultaneous management of the ABCs and addressing the likely elements in the differential. Think Hs and Ts. – Hypoxia (Place LMA or ETT, provide 100% oxygen) – Hypovolemia (Bedside ultrasound for free abdominal fluid/AAA, consider a NS bolus – if suspicion for hemorrhage is high, administer uncross-matched blood) – Hypo/hyperkalemia (Consider calcium chloride, especially in the patient with suspected renal insufficiency) – Hypoglycemia (Consider D50) – Hypothermia (Warm the cold patient) – Hydrogen ion/acidosis (Consider bicarb, especially if toxicology is suspected) – Toxins (In addition to bicarb, consider empiric antidotes – cyanide kit, digibind, naloxone, intralipid) – Tamponade (Perform bedside ultrasound) – Tension pneumothorax (Perform bedside ultrasound / consider needle or tube thoracostomy) – Thrombosis (Consider thrombolysis for AMI or, especially PE) – Trauma (The entire cranium and posterior thorax should be inspected if occult trauma is entertained) Although the administration epinephrine (and, formerly, atropine) is emphasized in codes, these agents do not benefit arrested patients. Your only chance to reanimate a patient in PEA or asystole is to reverse the underlying cause. Take your own pulse, take a step back, and think Hs and Ts.
