22 What Causes Pulmonary Edema? What doesn’t cause pulmonary edema?

23 Etiologies of NCPE Direct Injury Aspiration Inhalational injuries Near drowning Pulmonary contusion Diffuse Pulmonary infection Perina DG. Noncardiogenic pulmonary edema. Emerg Med Clinics of NA 2003;21:

24 Noncardiogenic Pulmonary Edema Adult Respiratory Distress Syndrome Opioids/Naloxone Salicylates Irritant Gases Amphetamines/ Cocaine Thiazide Diuretics Amiodarone/ Amphotericin/ Vinca Alkaloids/ Colchicine/ Ethchlorvynol

25 Indirect Injury Systemic Sepsis and septic shock Blood products transfusion reaction High altitude effects Drug overdose Neurogenic insults Pancreatitis Cardiopulmonary bypass Severe non-thoracic trauma Fat emboli Air emboli

26 Indirect Injuries Uremia Coagulopathies DIC

27 Common drugs Drug OD Heroin Methadone Aspirin Propoxyphene Ethchlorvynol Reed CR, et al. Drug-Induced Noncardiogenic Pulmonary Edema. Chest 1991;100:

28 NCPE Inhaled toxins Smoke Ammonia Chlorine Nitrous oxide Phosgene Methylene chloride

29 Rock Star Deaths Where did I keep those notes from Erickson’s lecture? Heroin Tommy Bolin, Sid Vicious, Janis Joplin, Billie Holliday, Dee Dee Ramone, Lance Krantz, Jan McAdam, Paula Yates, Eddy Shaver, Will Clay, Stacy Guess, Brad Nowell, Frankie Lymon, Neil Storey, Gregory Herbert, Judee Sill, Rick Evers, Roy Montrell, Danny Whitten, Dave Waller Cocaine Shannon Hoon, Wells Kelly, DJ Screw, Bobby Sheehan, Tommy Bolin, David Ruffin Barbiturates Jimi Hendrix, Judy Garland, Brian Epstein Amphetamines Hank Williams Other Zac Foley, Rob Pilatus, Elvis Presley, Keith Moon

30

31 I need an Atypical Rock Star Death Everything this guy usually takes could cause this! UDS negative for opiates, cocaine and amphetamines ? False negatives Synthetic opiate Keith Moon Heminevrine- Chlormethiazole being used for EtOH addiction.

32 Screw It Differential too large I’ve got better things to do I’m not feeling the love I need a new system approach

33 EKR Systems Approach to CPCs Apologies to Dr. Elizabeth Kubler-Ross

34 Denial I am good enough and smart enough and doggone it, people like me. I have plenty of time to figure out the CPC!

35 Anger How the hell do they expect me to figure out this CPC! Everything has a case report associating it with pulmonary edema! Where are my fellows when I need them!

36 Bargaining Who can I bribe to figure out this CPC? How can I cheat if at all possible?

37

38 Depression My differential just keeps getting larger. Maybe there will be another blackout. What do 4 out of 5 toxicologists recommend for an overdose?

39 Acceptance OK, the differential is enormous and there is little to narrow down the field so what answer is the most satisfying intellectually for an NACCT CPC?

40 What Would Elvis Do? What didn’t Elvis do?

41

42

43 The Shit That Killed Elvis Elvis died in the bathroom. Slang term for high grade marijuana Percodan Demerol Amphetamines Myriad sedative hypnotics Methaqualone Barbiturates Ethchlorvynol

44 Marijuana UDS positive for THC Doesn’t usually cause pulmonary edema Possible contaminant PCP Ketamine Paraquat

45 Methaqualone Used by Elvis Reports of Pulmonary Edema Schedule I since 1984 and reports are infrequent Kids are making everything these days

46 Ethchlorvynol Placidyl – sedative,hypnotic Used by Elvis Causes NCPE when injected not usually when taken orally After IV injection causes a minty taste in the mouth then dyspnea Abbott discontinued production in Is it available?

47 Ethchlorvynol The following ethchlorvynol cases have been reported to AAPCC TESS since 1/1/2000: 50 human cases as substance 1, no deaths 90 human cases total as one of the involved substances, no deaths

48 Does it Fit? Miller, KS, et al. Bilateral exudative pleural effusions following intravenous ethchlorvynol administration. Chest 1989;95: Conces, DJ, et al. Pulmonary edema induced by intravenous ethchlorvynol. Am J Emerg Med 1986;4: Glauser FL, et al. Ethchlorvynol (Placidyl) – induced pulmonary edema. Ann Intern Med 1976;84: Burton WN, et al. Adult respiratory distress syndrome after Placidyl abuse. Crit Care Med 1980;8: Swearingen PV. Placidyl and pulmonary edema. Ann Int Med 1976;84: Yell RP. Ethchlorvynol overdose. Am Journ of Emerg Med 1990;8:

49 Treatment Supportive Care PEEP Usually resolves within 72 hours Animal studies did show possible benefit in pretreatment with cyclooxygense inhibitors Nesiritide Bobadilla RV, et al. Nesiritide treatment of noncardiogenic pulmonary edema. Annals of Pharmacotherapy. 2003;37(4):

50 Other guesses Talc emboli Marijuana contaminant Just about anything
