The History of Resuscitation Timeline

3000 BC – Mayan hieroglyphics and cave drawings indicate that they and the Peruvian Incas in South and Central America performed rectal fumigation to attempt resuscitation.  This involves blowing hot air or smoke into the rectum of the casualty.

896 BC – “Then he got on the bed and lay upon the boy, mouth to mouth, eyes to eyes, hands to hands. As he stretched himself out upon him, the boy’s body grew warm.” (2 Kings 4:34)

1000 AD – A Muslim philosopher and physician known as Avicenna performed the first known experimental intubation of the trachea.  Gold, silver, or other metals were used in an effort to support inspiration.

1500 AD – The Heat Method and flagellation were invented and tried.  The heat method consisted of placing coals and hot ash onto the victim to counteract the cooling that death brings to the body.  Flagellation involved whipping the patient to stimulate a response.  These methods were both highly successful in awaking a deep sleeper, but futile resuscitative efforts.

1530 – The Bellows Method became very popular.  This involved using a fireplace bellow to ventilate the patient.  Unfortunately, airway anatomy was not very well known back then, and without hyperextension of the neck, the procedure didn’t work very well.  However, modern day bag-valve masks were inspired by this archaic procedure.

1543 – Vesalius et al. published “De humani corporis fabrica”.  This publication included descriptions of reviving animals by blowing into a tube.

1711 – For some reason, North American Indians and American colonists sought fit to bring back the rectal fumigation method.  Lets hope, this was the final comeback tour for this procedure—for the patients, their families, and most of all, our sake.

1740 – The Paris Academy of Sciences made an official recommendation for mouth-to-mouth for the resuscitation of drowning victims.  Of course it was the French who found benefit in placing their mouth on another’s.

1750 – Goodwin and Kite hypothesized that asphyxia caused the heart to stop; which was the ultimate cause of death.  They theorized that electrical shock (defibrillation) should be used to restart the heart.  Unfortunately this method was not appreciated because it required the victim be lain supine which caused the tongue to obstruct the airway.

1767 – The Society for the Recovery of Drowned Persons was founded and became the first organized group to take on sudden unexplained death.  This was also the year that The Dutch Humane Society published their instructions for resuscitating drowning victims.  They suggested keeping the victim warm, providing mouth-to-mouth, and once again, the dreaded rectal insufflations.

1770 – In Europe the leading cause of death at the time was drowning.  The Inversion Method became widely used to treat cardiac arrests from drowning.  This involved hanging the victim by his feet, often from a lifeguard tower.  The pressure on the chest would force expiration while it was though the release of that pressure would stimulate inhalation.  Lifeguards typically had to be pretty strong to lift the patients up and down repeatedly.

1773 – In an effort to provide artificial ventilation, the Barrel Method was invented.  The rescuer would lay the victim prone over the length of a large barrel.  He or she would then hold onto the patient by their feet and roll them back and forth.

1803 – The Russian Method was used, which may sound a lot like modern-day induced hypothermia.  This entailed placing the victim’s body under a bed of snow or ice in an attempt to slow metabolism.  Unfortunately, the brain was often left un-cooled, defeating the purpose.

1812 – Lifeguards became equipped with horses; which they kept tied to their lookout towers.  The Trotting Horse Method utilized these horses when a drowning victim presented.  The lifeguard would place the victim face down, draped over the horses back.  The horse would then be led to a trot, up and down the beach.  The bouncing of the victim’s chest on the horses back was thought to provide compression and relaxation.  This was banned in 1815 when citizens complained that their beaches weren’t clean enough.

1849 – A student, M. Hoffa, was the first to witness and document the onset of ventricular fibrillation after inducing it with an electrical stimulus.

1856 – Dr. Marshall Hall challenged conventional wisdom at the time.  He invented The Ready Method; which was aimed at providing artificial ventilation.  The rescuer would roll the patient from a lateral position to the prone position about sixteen times a minute, with pauses to provide pressure while in the prone position to facilitate exhalation.  This method was surprisingly successful for the time.  An article from September of 1859 in the Editor’s Box of the British Medical Journal describes a physician’s use of the method to resuscitate a baby, after he had thought he delivered a stillborn.

1858- The Silvester Method was introduced in an effort to resuscitate stillborn children.  The neonate would be laid supine and their arms would be lifted and then pressed against their chest.  A rate of about sixteen arm lifts per minute was advocated.

1881 – Clara Barton founded the American Red Cross.

1891 – Dr. Friedrich Maass performed the first equivocally documented chest compression on a human being after John Howard wrote about the procedure.

1892 – French authors wrote about the Tongue Method.  The victim’s mouth was held wide open while their tongue was rhythmically pulled back and forth.

1903 – It is reported that Dr. George Crile performed the first successful external chest compression to resuscitate a human.  A year later he performed the first closed-chest cardiac massage in America.

1911 – The first edition of the Boy Scout handbook in the United States contained the Holger Nielsen Technique.  The victim would be laid prone and their arms would be pulled on while pressure would be applied to their back.

1924 – Six cardiologists, representing several groups, founded the American Heart Association.

1932 – Dr. Frank C. Eve created his rocking method.  This entailed using a stretcher with a patient laid on it, almost like a seesaw.  It would be pivoted about its center in an effort to push the diaphragm alternately up then down.  The Royal Navy adopted it during WWII for resuscitation of near-drowning victims.

1947 – Dr. Claude S. Beck, a thoracic surgeon for the University Hospitals in Cleveland, performed the first electrical defibrillation to save a human life.

1952 – Dr. Paul Zoll resuscitated two cardiac arrest patients in Boston by utilizing external defibrillation.

1956 – Peter Safer and James Elam invented mouth-to-mouth resuscitation; after identifying that expired air alone was sufficient enough to provide adequate oxygenation.

1957 – The United States Military adopted mouth-to-mouth resuscitation to revive unresponsive victims.

1960 – W.B. Kouwenhoven, J.R. Jude and G.G. Knickerbocker began to use what was termed Cardiopulmonary Resuscitation or CPR.

1966 – The National Academy of Sciences published a report entitled Accidental Death and Disability: The Neglected Disease of Modern Society, or “the white paper”.  This placed pressure on the government to provide better ambulance services.  This was the year the DOT took over prehospital education standards.

1973 – The American Heart Association and the American Red Cross began an aggressive campaign to teach and instill CPR methods.  The rates and ratios have changed multiple times, but the fundamentals remained the same—ventilations and chest compressions.

1990 – The Chain of Survival became widely advertised by the AHA.

1996 – Emphasis was placed on early defibrillation.

2005 – AHA revisits basic life support, and places much more emphasis on chest compressions.  Therapeutic hypothermia is listed in the AHA guidelines as a potentially beneficial treatment for revived cardiac arrest victims.

Now – Cardiocerbral Resuscitation, or CCR de-emphasizes airway management, and reinforces AHA’s recommendations for better chest compressions.  The impedance threshold device has shown to improve cardiac and cerebral perfusion during CPR.  Evidence supports the transportation of revived cardiac arrest patients to a PCI-capable facility.

For your viewing pleasure:

This is something my training captain emailed to me about a year ago. It has always stuck in my head as the best medical-related study song I have ever heard or seen. Hope you enjoy.
PS. I will be working on a cardiology video tutorial. From anatomy to ECGs, in plain English. I am going to try and teach ECGs a little differently. This is something I always wanted as a student, I get tired of hearing people recite powerpoints. This is going to take a while, but keep a lookout.

Dear New Guy…

Dear New Guy,

Welcome to the wonderful world of ambulance driving. I specifically say “driving” because that will be your job until the medic you’re with gets over himself, retires, or dies. Please be cognisant of your own limitations. Just because you intubated airway Annie 92 times does not mean you will be good at it. In fact, pretend you suck at everything and go from there. You may have had straight A’s in school, this ain’t school.

Please understand that I am not angry, burnt out, or too proud. The things I am telling you are for your own good. You may be yelled at by your senior medic. Please understand that this is not a reflection of your stupidity, well probably not; it’s probably a reflection of the “old fart’s” lack of patience. You may feel like you know it all, you don’t, you never will.

Surprise, not every call is a dire emergency. In fact, most calls are more related to comfort than life. This may be hard to imagine after running megacode after megacode in your lab scenarios. You probably didn’t learn this stuff in medic school, be kind. Your patients are not made of stain resistant plastic, they are in fact flesh and bones. Empathy is a word you should look up and try to emulate.

It’s okay to freak out on scene, just don’t let anyone know you are. One day you will be a lead medic and all eyes will be on you. Your partner, the patient’s family, and anyone else on scene will freak out if you do. Move with a purpose, and look like you know what you’re doing. This may be the best advice anyone will ever give you.

Be obsessive compulsive. Nothing is ever too clean. You should know where everything is and how much you got of each. This is the practice of a good medic.

You can’t save them all, in fact you won’t save most. Get over it, learn from any mistakes you have made. This requires you first realize you aren’t perfect.

For God’s sake, give some pain control. If they say they hurt, you should probably believe them. Not everyone is heroin Hank, seeking a fix.

Contrary to what you may believe after reading this far, I love this job. This is the best job you’ll hate to love. Once you think you’ve got it all figured out, something new will humble you once again.

You will be underpaid, overworked, and under-appreciated. Don’t forget what it feels like right now, when you are brand new. If you come into work every day like you did on your first day, you will love coming in and hopping on that rig.

Sincerely,
yourself in five years

They put the "BS" in BLS

05/02/2009 by Adam Thompson, EMT-P 6 Comments

Don’t go jumping to conclusions based on the title of this post. Yes, the BS stands for exactly what you think. I however, am not a disgruntle burnt out medic, aiming to complain. Not yet at least.

My agency prioritizes calls into three categories. Priority 1, which would be an unstable ALS patient, priority 2, which is a stable ALS patient, and priority 3, a BLS patient. Many of us have added a fourth category, priority 4, sometimes referred to as priority 5. Priority 4 patients don’t quite meet the BLS criteria by our standards so they might be considered BS patients.
These patients seem to want to call us at the best time amongst our 24 hour shift, around 3am. There chief complaints range from a variety of medical emergencies, here are a few:
  • Cut finger
  • Can’t sleep
  • Can’t poop
  • Tired
  • Lonely
  • Scared
  • Can’t find my car keys
  • Barrack Obama is going to win the election
  • I’ve had a headache since 10 o’clock
Yes, these are all real complaints. I also realize that a few of them could be symptoms of a truly emergent medical condition. Sometimes it is something that the patient will deal with all day, just until the point where they can’t sleep. Once they can’t sleep it becomes an emergency, and who wants to use one of the 3 cars in the driveway, at 2am, to drive them to the ER? So if they can’t sleep, why should we?
Just in case you don’t believe that these are all real 911 calls, watch this:
Here is a pretty good news story:

This dispatcher has had enough, watch this:

Here is a transcript from a story NBC ran on our system. I had the luxury of escorting a reporter in our ambulance, wish I had the video.
LEE COUNTY: For 3 months, NBC2 Investigators have been working with emergency services collecting calls and riding with paramedics. We discovered a large number of calls coming into 911 are for anything but an emergency, which puts your safety at risk.

911 operator: What is the address of your emergency?
Caller: We are at the corner of Edison and Cleveland– 3 car accident at least with injuries

It’s Friday night and multiple calls are coming into the 911.

But this story isn’t about people who call 911 for a real emergency. This story is about the 40 percent of calls that aren’t for an emergency at all.

Some examples:

911: What’s your emergency?
Caller: Um, yes I locked my two keys in the car.

Caller: I’m depressed because [expletive deleted] Obama’s going to get the thing
911: What’s going to happen? Obama’s going to get what?
Caller: He’s going to get elected.

Caller: She needs to go to the hospital because she has a toothache

Caller: Yeah I ran out of gas.

Caller: I’m at the Chik Fil A on Colonial and I’m trying to get an ambulance to move and they won’t move. I’m parked here in the heat, I’m about to need an ambulance myself.
911: So, you are not having a real medical emergency right now?
Caller: It will be if I sit here in this heat any longer!

The four days we rode along with EMS, only 2 cases were truly life threatening emergencies.

“Typically 911 is the first thing people think of, and it’s the easiest thing because it’s guaranteed,” said Paramedic Robert Bertulli.

When people call 911 unnecessarily, it puts a strain on the system and puts your safety at risk.

“It happens all the time,” said Bertulli.

When crews are tied up on a call for a stubbed toe or nosebleed, EMS must shuffle ambulances and your ambulance could be coming from farther away.

“Inevitably someone’s going to suffer as a result of calls made that are unnecessary,” said Bertulli.

Only 20-percent of the calls that come into 911 are truly life threatening emergencies – like heart attacks.

Forty-percent of calls are emergencies – not life threatening, but serious enough you shouldn’t be driving to a hospital.

The remaining 40-percent of calls are not emergencies at all.[...]

I have a strong belief regarding these calls. I believe the most extreme are a little ridiculous. I think calls like these add to bad attitudes and burnt out personnel. I also thank God for some of them, because I wouldn’t have a job if all we ran were true emergencies. I don’t mind holding a hand here or there, if it means I can still have a job. Our agency would be able to cut our resources in half, if it wasn’t for the priority 3 and “priority 4″ calls. We are paid by Joe Citizen, so I am willing to respond for whatever he needs. I will do my job, and I will explain when not to call 911 to someone who apparently has no clue, but I’m not going to become disgruntle over it.
These calls also create this sense of “everything is bullshit” amongst some providers. On the way to a call I will notice some partners complaining before we get there. “This is going to be BS”. I think this is dangerous because it puts you a step behind if it’s a true emergency.
Think about it, if you are expecting a patient to be drunk and end up with a cardiac arrest, how much gear changing do you have to do? I like to expect the worst and be relieved when I get there. It’s hard sometimes to do, but it works for me.
Also, think about how much you can do by just holding a patient’s hand and reassuring them. How many lives you can save without having to do CPR. What I mean by that is, education. Maybe you can catch a suicidal teenager in their teachable moment. That means that they might be a little more receptive at the exact moment you are there. You could save their life and never even know it; or do you need a pin for your shirt collar?

There are good points on both sides of this discussion. Feel free to share your views.
****Update May 4, 2009****
Sure enough, after writing this, I have the greatest example of a shift. We work 24 hour shifts here, and I just ran six calls during my shift, and had zero transports. Here are what my calls consisted of:
  • The first call of the day was for a drunk lady that had a family that was sick and tired of her. They were stating that she couldn’t drink anymore or she was going to kill her liver. The patient adamantly didn’t want to go to the hospital, and this doesn’t count as being a threat to yourself or others. Refusal #1.
  • Next we we responded to a possible man down at the boat ramp. We had no idea what we were even looking for. The dispatch notes stated that a man was dropped off by a boat at the boat ramp. The man’s wife called through onstar, and she was not on scene. We ended up actually finding the guy, who was sitting on a bench waiting for his wife to give him a ride. Apparently his phone died and his wife was scared when she couldn’t get ahold of him. Refusal #2.
  • Next up, a fender bender. Not much explaining needed here, no injuries to anyone on scene. Refusal #3.
  • Next was a pedestrian hit by a vehicle. This wasn’t as bad as it sounds, the car was backing out of a parking space and knocked someone off their bike. The patient was a a law enforcement substation with a laceration on his elbow. He just wanted to get checked out. He knew he didn’t want to go to the hospital. Thank you LE for having us dispatched for a bandage! Refusal #4.
  • Next up, another bicycle accident. Patient had a recent history of stroke, with unilateral deficits. The patient decided he wanted to get back on his bike. The bike didn’t think it was time yet, and threw him off. The patient had some small lacerations to his ankle from the sprocket. He didn’t want to go to the ER. Refusal #5.
  • Finally, epistaxis at 3am. Mild hypertension, nothing much else to explain here. He went POV. Refusal #6.
This isn’t a regular shift, just thought I’d share it since it’s so relevant.
*****
Here is something I found on PubMed. It’s a research survey on the geographical differential of ambulance use. Appropriateness is emphasized.
American Journal of Emergency Medicine, Feb. 2009.
Nordic School of Public Health, SE 402 42 Göteborg, Sweden. lena-marie.beillon@preem.se
AIM: The aim of this study was to analyze possible differences in the use of ambulance service between densely and sparsely populated areas. METHODS: This study was designed as a 2-step consecutive study that included the ambulance service in 4 different areas with different geographical characteristics. A specific questionnaire was distributed to the enrolled ambulance services. Completion of one questionnaire was required for each ambulance mission, that is, 1 per patient, during the study periods. For calculations of P values, geographic area was treated as a 4-graded ordered variable, from the most densely populated to the most sparsely populated (ie, urban-suburban-rural-remote rural area). Statistical tests used were Mann-Whitney U test and Spearman rank statistic, when appropriate. All P values are 2 tailed and considered significant if below .01. RESULTS: The medical status of the patients in the prehospital care situation was more often severe in the sparsely populated areas. In addition, drugs were more often used in the ambulances in these areas. In the sparsely populated areas, ambulance use was more frequently judged as the appropriate mode of transportation compared with the more densely populated areas. CONCLUSIONS: Our study suggests that the appropriateness of the use of ambulance is not optimal. Furthermore, our data suggest that geographical factors, that is, population density, is related to inappropriate use. Thus, strategies to improve the appropriateness of ambulance use should probably take geographical aspects into consideration.
