Will IV Oxygen Save Lives?

by Rogue Medic in Rogue Medic

Intravenous oxygen delivery that works?

Maybe temporary oxygenation, but not yet.

Will this change the approach to CICV (Can’t Intubate, Can’t Ventilate) patients?

No, but it may change the approach to CICO (Can’t Intubate, Can’t Oxygenate) patients.

The distinction is important. ... Read more »

Is Nitroglycerin Bad for Severe Sepsis?

by Rogue Medic in Rogue Medic

Yesterday at "The Paramedic's Edge," this was the topic of discussion of a possible use of NTG (NiTroGlycerin – GTN GlycerylTriNitrate in Commonwealth countries).

NTG is a vasodilator and sepsis is a vasodialtion problem. There are other problems with sepsis, but vasodilation may be the primary problem.... Read more »

Counterintuitive Conservation

by Emarkham in GeneticCuckoo

An analysis of the proposal to legalize the trade in rhino horn in order to reduce the poaching of the remaining wild rhinos. Legalizing the trade of rhino horn is claimed to reduce the demand on the black market and is likely to be the best method for conserving the remaining rhinos, however other factors can influence the potential success of this. ...

Does the Goal of a Pulse Lead to Bad Resuscitation Decisions

by Rogue Medic in Rogue Medic

The paper does address some interesting aspects of resuscitation.

ROSC (Return Of Spontaneous Circulation) is the goal for many people.

ROSC is a red herring.

Those of us who think ROSC is important do not seem to understand how much long-term damage we can do in our attempts to get ROSC, or to get ROSC quickly.

This study helps to point out some of the inconsistencies with our ROSC fetish.... Read more »

Equipoise and Ethics and IRBs, Oh My!

In the comments to what I wrote yesterday about seizures and a study comparing lorazepam (Ativan), diazepam (Valium), and placebo,[1] Brooks Walsh had the following comment –

"Although I’ve read the study before, I am only wondering now how the IRB for Alldredge 2001 thought there was 'equipoise' between placebo and benzos."... Read more »

Should We Use Immobilization For Penetrating Injuries To The Neck - Comments at Paramedic's Edge

Japanese man dies after 25 hospitals reject him

by Rogue Medic in Rogue Medic

In January, in Japan, 25 hospitals refused to permit an ambulance to transport a man who was pronounced dead when he finally arrived at a hospital.

Were the patients already in the ED (Emergency Department) less stable than this patient?

Was this patient going to be the straw that breaks the camel’s back and result in the deaths of other patients already in the ED?

What kind of evidence do we have to justify diversion?

Bougies and ALS Airways

Does Intubation Prevent Aspiration of Stomach Contents?

by Rogue Medic in Rogue Medic

This is a study that looked at the rate of aspiration among patients intubated in the PH (PreHospital or EMS) setting and compared them to patients intubated in the ED = (Emergency Department) setting.

There is one huge difference between these settings – EMS was not authorized to use any form of chemically assisted intubation or RSI (Rapid Sequence Induction/Intubation). At the time of this study, the only drugs available to snow the patient would have been morphine, midazolam (Versed)........ Read more »

Good Can Come From Bad: Genetic Testing For The BRCA Breast Cancer Genes

by Jalees Rehman in The Next Regeneration

Our ability to test for the presence of genetic mutations has become extremely cost-efficient and private companies, such as 23andMe now offer genetic testing for consumers who want to find out about their predisposition for genetic diseases. The results of such tests are sent directly to the consumers, without the involvement of genetic counselors or other healthcare providers. This has lead to a growing concern about how people will respond to finding out that they are carriers of mutations th........ Read more »

Advanced Airway vs. BVM During CPR – Which is Worse?

by Rogue Medic in Rogue Medic

The authors wanted to find out what method is (worst) best for ventilating patients during out-of-hospital treatment of cardiac arrest.
Endotracheal tube?
Supraglottic airway (laryngeal mask airway, laryngeal tube, and esophageal-tracheal twin-lumen airway device)?
BVM (Bag Valve Mask)?
This assumes that ventilations provide some sort of benefit to the patient. There is no evidence to support this myth.... Read more »

EMS Time and Survival from Blunt and Penetrating Trauma

Dr. David H. Barlow and Aversion Therapy for Gays

by The Neurocritic in The Neurocritic

Should a professional society honor a highly accomplished investigator who conducted studies in the past that would now be considered unethical?

Barlow was recognized for his achievements by the Association for Psychological Science (APS) last year as the recipient of the 2012 James McKeen Cattell Fellow Award:David H. Barlow has made enormous theoretical and empirical contributions in many areas of clinical psychology. He is best........ Read more »

If the patient is asleep, does that mean that the pain is gone?

by Rogue Medic in Rogue Medic

Is it appropriate to stop giving pain medicine just because the patient is asleep?

My little burned patient was probably not expressing relief from pain with her periods of unresponsiveness – especially since she had not received anything for her severe pain. Each time that she woke up screaming, that was also a clue. the medical command doctor’s orders were to give no pain medicine.[1]

Is propofol effective at putting patients to sleep without relieving their pain?

More evidence that antibiotics are over-prescribed - How should that change?

by Rogue Medic in Rogue Medic

Today Lancet Infectious Diseases posted an early release of an article that shows that the antibiotic amoxicillin still does not work on viruses.

Many doctors still routinely prescribe antibiotics for viral infections.

Bias, perhaps the biggest confounder in medical research, is controlled for very well.

What does the study show?... Read more »

Ten days ago, I asked you all a question in a poll and I promised to let you know the results.

POLL: Very premature babies

by GDW in The Beast, the Bard and the Bot

Preterm birth is risky. And, not surprisingly, the earlier a baby is born, the greater the risks. Two new studies (part of EPICure) address the survival and further development of babies born way too soon (after between 22 and 26 weeks of gestation). The studies found that survival has increased, when comparing premature babies born [...]... Read more »

Is Digoxin a Killer?

by Rogue Medic in Rogue Medic

Digoxin (Lanoxin) is an antiarrhythmic drug, which means that it is also a proarrhythmic drug. Any drug that affects the heart’s conduction system can produced changes that are bad, good, or a combination of the two. Digoxin has been associated with a higher death rate, but is that because it is prescribed to sicker patients?... Read more »
