This week we discuss 3 articles recently reviewed in our conference - LOV-ED study, Validation of Step-By-Step and Therapeutic Hypothermia. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_99_0_Final_Cut.m4a Download Leave a Comment Tags: ARDS, Cardiac Arrest, Lung Protective Ventilation, Mechanical Ventilation, OHCA, Step-By-Step Protocol, Therapeutic Hypothermia, TTM Show Notes Take Home Points The step-by-step approach to managing febrile infants is a reliable decision instrument to identify patients at low risk for invasive bacterial infections. Caution in the group of patients 22-28 days of age. The LOV-ED study shows an association between employing a lung-protective ventilation strategy in the ED and decreased complications from mechanical ventilation. Best available evidence says that we should embrace this approach in the ED. Cooling to 33 degrees is no better than cooling to 36 degrees. However, shooting 36 degrees is more difficult than we may have thought. We have to continue to be vigilant about maintaining patients in the target temperature range and avoiding fever.

This week we discuss the rare but life-threatening methemoglobinemia with a focus on recognition and use of the antidote. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_97_0_Final_Cut.m4a Download 2 Comments Tags: Methemoglobin, Toxicology Show Notes Take Home Points MetHb –emia occurs as a results of various medications including amyl nitrite, dapsone, nitroprusside, phenazopyridine, sodium nitrite and topical anesthetics like benzocaine Patients will present with cyanosis, short of breath, fatigue, dizziness, weakness and ultimately CNS depression and death at higher concentrations. If you have a cyanotic/hypoxic patient that does not respond to supplemental oxygen, be concerned for MetHb and send a co-oximetry panel. If the level is <25% and the patient is asymptomatic you can observe, but if the level is >25% or the patient is symptomatic, you will treat with the antidote methylene blue given as a bolus of 1-2 mg/kg over 5 minutes And as always, make sure to call your local poison center to get your toxicologists involved. They can help with dosing, and they are also an important player of the public health component in cases such as these, to make sure this is an isolated incident and we don’t have a repeat of the 11 blue men situation.

This week we do a brief review on recognizing CO monoxide poisoning and expertly managing it. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_96_0_Final_Cut.m4a Download Leave a Comment Tags: CO, Inhaled Toxins, Toxicology Show Notes Take Home Points CO poisoning happens most often from common are accidental exposures from faulty home heaters, camp stoves and indoor use of gas powered generators, structure fires and intentional exposure like in suicide attempts. Patients with a mild exposure will present with symptoms like headache, nausea, vomiting, dizziness, vision blurring, palpitations, confusion or myalgias.  More severe exposures may produce Altered mental status. seizures, coma, dysrythmias, myocardial ischemia, metabolic acidosis, syncope and vital sign abnormalities including hypotension and, eventually, cardiac arrest. To help distinguish the vague symptoms of a patient who may have chronic exposure ask about things like whether symptoms improve in different environments or whether they have sick pets, as human viral illness generally don’t affect our dogs and cats. If you’re concerned about CO send a co-ox panel.  City dwellers may have a baseline carboxyhemoglobin of 1-2% and smokers around 6-10% but others should really have no carboxyhemoglobin. Treatment is supplemental O2 which can be stopped when symptoms improve.  For severe symptoms and for pregnant patients, consider hyperbarics to prevent long term sequelae and to protect the fetus.  As always, consider discussing the case with your local poison center to help decide whether a patient warrants transfer for hyperbarics.
