PCRF Research Podcasts

The Prehospital Care Research Forum is dedicated to fostering and improving research in EMS. Below you will find select podcasts discussing current research that affects EMS. These podcasts are meant to review methodology and applicability to prehospital care, promote healthy and respectful discussions, and inspire new research. We encourage you to comment on the podcasts and make suggestions as to how we can improve this feature.

Differences in Long Term Mortality after Acute Poisoning by David, Alexander, Chris, Keith

This podcast features the discussion of a study conducted by Dr. Catherine Lund of Oslo, Norway. The study illustrated the differences in long term mortality of acute poisoning patients based on the care they were given in a prehospital, clinical or hospital setting.

Speakers: David Page, MS, NREMT-PAlexander Trembley, NREMT-PKeith Wesley, MD, FACEP, Chris Schultz, MHA, EMT-CP

Original article: "Five-year mortality after acute poisoning treated in ambulances, an Emergency outpatient clinic, and hospitals in Oslo," by Cathrine Lund, Mari A. Bjornaas, Leiv Sandvik, Oivind Ekeberg, Dag Jacobsen, and Knut E. Hovda.

Resuscitation Fluids by David, Alexander, Keith

A review article entitled "Resuscitation Fluids," written by John A. Myburgh, M.B., B.Ch., Ph.D. and Michael G. Mythen, M.D., M.B., B.S., was published this year in the New England Journal of Medicine. The article analyzed the use of fluid resuscitation in both the prehospital and hospital settings, examining both the physiological principles and clinical practices involved in selecting from the many types of fluid resuscitation available.  Normal saline was ultimately determined to have the broadest application in the prehospital and hospital settings, while other methodologies proved to have certain setbacks.  The article offers a good review of the intricacies of human pathophysiology and fluid resuscitation.  It reiterates the evidence that defining and correcting the etiology of the patient's hypovolemia is a more definitive treatment than fluid resuscitation.

The Effect of an Ambulance Diversion Ban by David, Alexander, Marshall, Joshua, Keith, Kelsey

A recent study conducted by Burke, M.D., et al. illustrated the positive effects of a 2009 ban on diversions in Massachusetts hospitals.  The study, entitled "The Effect of an Ambulance Diversion Ban on Emergency Department Length of Stay and Ambulance Turnaround Time," revealed a 3.6% increase in ED volume associated with a 10.4 minute decrease in patient stay for admitted patients.  Ambulances also had a 2.4 minute decrease in turnaround time.

Muscles used for chest compression under static and transportation conditions by David, Alexander, Marshall, Joshua, Keith, Kelsey

A study performed in Japan by Dr. Yasuda et. al detailed the muscle groups used in performing stationary CPR and while in a moving ambulance.  Results from this study published in "Muscles used for chest compression under static and transportation conditions" demonstrated that the rate and depth of compressions showed no significant difference between the two conditions, but that the overall effectiveness of CPR was significantly decreased while in a moving ambulance.

Does your ambulance service piggyback glucose with thiamine? by David, Alex, Marshall, Josh, Keith, and Kelsey

IV thiamine administered with glucose was previously believed to prevent Wernick’s encephalopathy (brain damage particularly in the hypothalamus and thalamus due to thiamine deficiency) within the prehospital setting.
