AIR Series: Infectious Disease, Hematology, Oncology 2014

By |Categories: Approved Instructional Resources (AIR series), Heme-Oncology, Infectious Disease|Tags: |

Welcome to the first ALiEM Approved Instructional Resources (AIR) Module! In an effort to reward our readers for the reading and learning they are already doing online, we have created an Individual Interactive Instruction (III) opportunity utilizing FOAM resources for US Emergency Medicine residents. For each module, the board curates and scores a list of blogs and podcasts. A quiz is available to complete after each module to obtain residency conference credit. Once completed, your name and institution will be logged into our private Google Drive database, which participating residency program directors can access to provide access. [+]

New AIR Series: ALiEM Approved Instructional Resources

By |Categories: Approved Instructional Resources (AIR series)|Tags: |

On behalf of the AIR Executive Board, we are excited to introduce the Approved Instructional Resources (AIR) series! The AIR series was conceived to provide a credible method by which an U.S. Emergency Medicine resident can receive academic credit for using Free Open Access Meducation (FOAM) resources. The Executive Board will release a list of high-quality FOAM educational posts and podcasts specially selected by our Executive Board, in parallel with the CORD residency training curriculum. We will have an accompanying quiz for each list and track who completes it. EM residents who complete the quiz can hopefully receive credit for Individualized Interactive Instruction (III) from their EM residency [+]

PV Card: Pediatric Ingestion Dose Thresholds for ED Referral

By |Categories: ALiEM Cards, Expert Peer Reviewed (Clinical), Tox & Medications|

Clinical Toxicology has published guidelines for out-of-hospital management of 16 distinct overdoses and their dose thresholds, above which, pediatric patients should be referred to the Emergency Department for evaluation. Clinical Toxicology is the official journal of the American Academy of Clinical Toxicology (AACT, @AACTinfo), the American Association of Poison Control Centers (AAPCC, @AAPCC), and the European Association of Poisons Centres and Clinical Toxicologists (EAPCCT). There are two caveats to be aware of regarding these guidelines. They were developed between 2005 and 2007. New medications have been approved since that time and there may be more recent data available. As with any poisoning, dose is [+]

Intraosseous Rapid Sequence Intubation

By |Categories: Critical Care/ Resus|

Intravenous (IV) rapid sequence intubation (RSI) is by most considered the gold standard practice for securing an airway in the critically ill. There are, however, scenarios where it may not be possible to get rapid IV access in a timely manner (i.e. severe cutaneous burns, hemorrhagic shock, IV drug users, and/or the morbidly obese). It has been reported that intraosseous (IO) drug administration has similar pharmacokinetics to IV administration, but there have only been a handful of cases reported using the IO route for RSI. In this post we will discuss intraosseous rapid sequence intubation and if it is a feasible [+]

Anxiolytics and Hypnotics: Are They Doing Harm?

By |Categories: Psychiatry, Tox & Medications|

A patient presents to the emergency department complaining of increasing insomnia due to anxiety. She states that she is not actively suicidal nor homicidal but she has trouble “turning off her brain” at night in order to sleep and her insomnia is worsening her anxiety. She has a history of morbid obesity and smokes 1 pack of cigarettes per day. In order to help you consider writing her a prescription for 5 mg of zolpidem as you presume it to be a benign way to deal with her current sleep disorder. But what does the evidence say about these drugs [+]

tPA Administration: Don’t Forget the Leftover Volume in the Pump Tubing

By |Categories: Tox & Medications|

Whether alteplase (tPA) is given for ischemic stroke, pulmonary embolism, or STEMI, there is an important practical issue to be aware of during administration. Dr. Charles Bruen (@resusreview) published a great step-by-step pictorial tPA Mixing Tutorial. Once the tPA is mixed, it will invariably be infused via a smart pump through its corresponding tubing. At my institution we use Alaris® CareFusion smart pumps, through the principle applies irrespective of which brand pump is used. [+]

PV Card: Local anesthetic toxicity calculations

By |Categories: ALiEM Cards, Expert Peer Reviewed (Clinical), Pre Publication Critique (Clinical), Tox & Medications|

Local anesthetics (LAs) are widely employed to achieve tissue infiltration, peripheral and regional anesthesia, and neuraxial blockades. Despite their well-established toxic dose limits, these agents continue to pose a substantial risk of morbidity and mortality due to local anesthetic toxicity and overdose. For example, LAs and epinephrine account for a large proportion of medication errors resulting in adverse patient outcomes due to drug dosing miscalculations or errors converting between units. Dosage calculations vary by patient weight as well as by pharmacokinetics and pharmacodynamics of individual LA formulations. Further, non-standard units, additives (epinephrine), and varying concentrations among LAs complicate correct dosage [+]

High risk back pain: Cauda Equina Syndrome (EREM)

By |Categories: Medicolegal, Orthopedic|Tags: |

Cauda equina syndrome (CES), which occurs due to compression of the distal lumbar and sacral nerve roots, is a potentially devastating cause of back pain. CES is often missed on the patient’s initial visit which can lead to  significant neurologic compromise in a matter of hours [1]. To improve patient outcomes and minimize medicolegal risk, providers need to understand the limitations of the history and physical and carefully consider the diagnosis of CES in any patient with back pain.

Atrial Fibrillation Rate Control in the ED: Calcium Channel Blockers or Beta Blockers?

By |Categories: Cardiovascular, Tox & Medications|

Rate control with IV medications is recommended for atrial fibrillation in the acute setting in patients without preexcitation. This was a Class 1 recommendation (Level of Evidence B) per the 2014 AHA/ACC/HRS Guideline for the Management of Patients With Atrial Fibrillation [1]. What does the evidence say? Are calcium channel blockers or beta blockers better? [+]
