Perspective of ECMO/ECPR simulation

I’ve been enthusiastic about providing ECMO simulation for these several years.

In 2013, I created a half-day ECMO sim at Simulation Center of Tohoku University Hospital in Sendai and I’ve been holding this simulation almost every single month for ECMO practitioners.

This is focused on VA-ECMO at Emergency Department. ELSO guideline was used as a reference. In order to make it possible for learners to practice ECMO cannulation and initiation of ECMO, I developed a low cost imitated vascular model named “Endo-Circuit”.

Recently I published a research about the long term efficacy of my ECMO simulation with the “Endo-Circuit” on peer-reviewed journal; “Acute Medicine & Surgery”, doi: 10.1002/ams2.236

My research revealed that many ECMO practitioners in Japan have some sort of PROBLEMS and FEARS about ECMO practice before simulation and then they have gotten some positive change in their knowledge, skills and attitudes after simulation. Since this research was only based on their retrospective self-evaluation, it’s unsure that their actual ECMO practices have been changed and lead to safer management. However some of their answers show that their usage of ultrasound for needle puncture and confirmation of guidewire placement during cannulation increased than before.

Even though the model is less expensive and imperfect in terms of anatomy of cardiovascular system, their evaluation about the circuit as a training model is relatively high. In order to keep quality of ECMO practice, this kind of simulation should be provided constantly.

In addition to my ECMO simulation, Japanese Circulation Society (JCS) and Japanese Resuscitation Council (JRC) had developed a one-day post cardiac arrest syndrome (PCAS) care training course in 2014 including ECMO skill training with “Endo-Circuit” and added an integrated ECPR team simulation in 2016.

Fortunately I got a fantastic opportunity to talk about JCS PCAS care training with my original training model at AHA/JCS Joint Session of Resuscitation Symposium in 2016 in New Orleans.

On Nov 12, I gave a 20-min presentation about our special educational experience including ECPR video for enthusiastic ECMO/ECPR providers attending the session. I had practiced my presentation a lot before the session and indeed my presentation was successful in terms of letting them know our project. There were some respected resuscitation researchers at the session. It was an amazing experience. My counterpart was Dr. David F. Gaieski and he talked about current US status of ECPR implementation and training. There were some hot discussions related to this topic.

On Nov 13-14, I did a ECPR cannulation Demo at JCS Booth in Exhibition Hall. Several attendees enjoyed my training model and some gave me compliments about it. I spent such a fantastic time in New Orleans.

ECPR is always challenging in terms of cost, human resources, time sensitivity, difficulty of cannulation, combination with TTM, uncertainty of heat and neurological recovery etc.

To make ECPR validated, I believe the standardized training including cannulation practice should be held for every advanced resuscitation provider repeatedly like BLS/ACLS.

I want to stay in touch with current enthusiasm about ECMO/ECPR and keep providing decent simulation seminars for practitioners.

I attended 2016 IMSH in San Diego in mid-January.

I enjoyed not only scientific meeting but other activities such as visiting ED-ECMO experts in SHARP Memorial Hospital, going to Cororado and  running around the bay area in the morning .

Even though I had been frustrated with my poor English skill, I could get a lot of information about cutting edge knowledge of simulation education and create new connection with other sim experts.

Happy New Year 2016!!

Happy New Year to Every Enthusiastic Simulation Expert!

The first post of this year is all about my very best simulation named “SimMarathon”.

I completed the 16th SimMarathon on December 29, 2015.
This endurance type crazy simulation seminar is definitely challenging for both facilitator and learners. If we were not enthusiastic about learning, it would make them stressed out by heavy tasks.

I love this simulation because there are very few fakes in terms of environment, patients’ data and devices used in this simulation.

This time, more than 20 healthcare providers joined and completed rather tough scenarios including two ECMO initiation, one REVOA and many Rapid Sequence Intubation (RSI) procedures for shock patients.

I have always wanted to add something new in this seminar, then one idea came up to my mind. That was an electric medical record, EMR. This time I let them write or add each patient’s information on pre-formatted word text and review them after each scenario finished. Even though the rpre-formatted style was not perfect yet, such tool will lead to much more realistic and effective education especially for young doctors.

Scenarios are as follows:

40M
CC: severe headache, vomiting
Diag: SAH(ruptured Acom aneurysm) with Takotsubo cardiomypathy
PH: none
Interventions: diazepam for seizure, brain CT, RSI→3D-CT Angio

44M
CC: burn
Diag: large burn by explosion, face to leg, TBSA 40%
PH: none
Interventions: fluid resuscitation based on Parkland formula, bronchoscopy and RSI, burn wound care

51M
CC: Trauma by falling from 4m height
Diag: traumatic SAH→VF due to AMI(Cardiogenic shock)
PH: HT
Interventions: Failed ACLS→VA-ECMO(ECPR) to manage persistent VF→PCI(POBA)

19M
CC: motorbike accident, blunt trauma, rt. chest pain
Diag: rt tension pneumothorax, rib fracture, aortic injury, lung and liver contusion
PH: none
Interventions: needle decompression→chest tube, CECT, IVR, BP control

53M
CC: altered consciousness, vomiting, sweating, miosis, fasciculation
Diag: organophosphate poisoning
PH: HT, HL, depression
Interventions: airway emergency by massive secretion→RSI, atropine + PAM

50F

Diag: pelvic fracture, multiple limb fractures, hemorrhagic shock, rt. pneumothorax
PH: very early phase of pregnancy
Interventions: transient responder →REVOA(IABO), blood O-type transfusion → CECT→TAE to blt internal iliac arteries

Report of SimMarathon in Autumn, 2015

I’ve forgotten to upload about my original simulation seminar called “SimMarathon” that was held on Nov 3rd, 2015.

At that time, 11 doctors and 6 nurses participated in this simulation.
They were divided into two teams and managed scenarios one after another.
Two doctors were attending emergency physicians and both gave a lot of comments and tips for young doctors.
Even though each scenario was so sick and difficult to handle, they did their best to make the patients stable as a team.
I had prepared 10 scenarios for this 8-hour sim, but just 7 scenarios were completed.
Especially ECMO scenarios took longer time than other ones, for example more than 1.5 hours for persistent VF scenario.
I know that too much complicated and comprehensive scenario that has bunch of teaching points is not suitable for less experienced learner, but that is the case they will have to deal with in the near future.
 Scenarios were as follows;

55M
CC: dyspnea, altered consciousness
Diag: severe pneumonia of Legionella
Interventions: intubation/EGDT/ABX→ventilatory support

60M
CC: hypothermia, fine VF
Diag: accidental hypothermia with GI bleeding
Interventions: ECMO, defib after rewarming more than 30 degree, massive blood transfusion, endoscopic/operative hemostasis

20F
CC: blunt trauma, hemorrhagic shock
Diag: facial trauma, hemorrhagic shock due to fractures of pelvis and multiple limbs
Interventions: cricothyroidotomy for airway emergency with multiple facial bone fractures, massive blood transfusion, FAST/FACT→TAE→external fixation of pelvis

60M
CC: lt.hemiparesis, altered consciousness
Diag: AAD(Stanford A), dissection 3 branches of aortic arch, seizure
Interventions: intubation, CE-CT→ope

20F
CC: altered consciousness, fever
Diag: bacterial meningitis/septic shock/sepsis-induced cardiomyopathy
interventions: blood culture, intubation, EGDT, early ABT administration(MEPM/VCM), CT, lumbar puncture

44M
CC: burn by explosion, face to leg,
Diag: large burn with inhalation injury, TBSA 40%, hemoglobinuria
Interventions: fluid resuscitation according to Pakland formula, bronchoscopy, intubation, wound care

51M
CC: Fall from 4m hight, VF during CT scan
Diag: traumatic SAH, rib fractures, transverse process fracture of lumbar spine, retroperitoneal hemorrhage,
new onset of AMI(broad anterior), persistent/reccurent VF
Interventions: VA-ECMO, PCI(only POBA) with minimum heparinization

REBOA Insertion Training

This is the first time for me to let learners put the real REBOA catheter into my original water vascular circuit made for ECMO training.

REBOA means “Resuscitative Endovascular Balloon Occlusion of the Aorta”. This is used for temporary control of life-threatening hemorrhage caused by trauma or other etiology like AAA up until definitive therapy will have been done.

Actually, my circuit worked well!

I’ve realized that my original circuit is quite useful not only for  ECMO training but also trauma simulation 🙂

Since the internal diameter of this vascular model is about 12mm, full inflation of the balloon couldn’t be done in this model.

My Experience of 5 min Q-CPR Challenge!

Yesterday, I tried 5min continuous chest-compression challenge with ResusciAnn with Q-CPR of Laerdal company. This time I chose the challenge without ventilations.

Challengers have to compress the chest just between 5.0 and 6.0 cm in depth without any aids such as metronome, depth indicator and countdown timer.

If they compress either less than 5.0cm or more than 6.0cm, that’ going to be judged inappropriate. In addition, the speed and chest recoil (or leaning) are also being evaluated during the challenge.

For me, five minutes were a little bit long and demanding, actually.

The result (Photo) was not the perfect one. Even though the speed of 111/min and chest recoil were perfect, the mean depth was 6.1cm!IMG_2360

I just compressed 0.1cm too much for 5min on average. It’s a shame!!

I realized that doing compressions in depth between 5.0 and 6.0 cm based on 2015 CPR guideline is a kind of an artistic performance for professional healthcare providers!

SimNight on Oct 27, 2015

This night, 2 young doctors, 1 nurse and their senior doctor participated in this simulation.
I gave just one scenario of a severe community acquired pneumonia patient that has several teaching points.

It took about 50 min for them to complete the scenario and then I did about one hour thorough debriefing.

After the scenario, these young docs seemed to be overwhelmed by the severity of the patient and their lack of ability to manage this patient. One of them said  “I’ve realized what I don’t know and what I should learn now.”

I believe this Sim has gotten them motivated and urged them to learn about emergency medicine more.

【Case】 55 years old, MaleCC: dyspnea, altered consciousness
PH: HT
By ambulance
Condition: severe pneumonia of Legionella, tachycardic AFib → NPPV:unsuccessful→intubation/EGDT/ABX(LVFX)→ventilatory support

Next SimMarathon in Winter!

I want to share the information about the next SimMarathon in SIMSTAR before the official announcement.
SimMarathon in Winter 2015 will be held on Dec 29 in SIMSTAR.
I’m not sure that I’ll be able to continue this crazy simulation seminar in 2016 as well.
If you want to experience comprehensive simulation about any kinds of emergency patients, why not join it!

I will wear one of our new LOGO-printed shirts 🙂

2015 SimMarathon in Okinawa “Chura-Sim” Center

On July 26, SimMarathon in Okinawa clinical simulation center was done as scheduled. This center’s nickname is “Chura-Sim”.  “Chura” means “beautiful” in Okinawan dialect. As it is, this center is very beautiful and well-equipped for training.

This time, all participants belong to a certain private hospital near this center.

An experienced doctor Mito who is a friend of mine since 2001 is in charge of emergency room of the hospital and invited me as a director of this simulation seminar.

More than 20 people joined and completed 8 scenarios as follows.
I really appreciate this remarkable facility and Dr Mito’s enthusiasm about simulation education.

In addition to holding seminar, I went to Okinawa’s sacred spot called Seifa-Utaki and then Syuri-Castle. Of course I enjoyed lots of local yummy foods.
