Patwari Academy videos: EBM Treatment Studies (part 2)

By |Categories: Patwari Videos|Tags: |

Dr. Rahul Patwari continues with the fourth and fifth videos in this series on Evidence Based Medicine (EBM) and Treatment Studies (see first three videos). These two videos are about the concept of Confidence Intervals and Patient Applicability. The second video below makes great points about whether a published study is applicable to YOUR patient. Don’t fall into common traps. […]

Ultrasound-Guided Pericardiocentesis

By |Categories: Cardiovascular, Ultrasound|Tags: |

All the years of ultrasound training in residency has paid off. You found the large pericardial effusion in the hypotensive patient who is still alive, but looks sick. You are a star! The only problem was that you never performed a pericardiocentesis in an awake patient. The cardiology fellow is at home sleeping and/or the closest receiving hospital is about 1 hour away. Now what? Dr. Arun Nagdev reviews how to do an ultrasound guided pericardiocentesis as part of this new, ongoing series of advanced ultrasound tips for emergency physicians. […]

Choosing the right vasopressor agent in hypotension

By |Categories: Critical Care/ Resus, Expert Peer Reviewed (Clinical), Tox & Medications|

The incidence of critical illness in the ED is rising, with greater than 1 million ED patients requiring emergent resuscitation each year. In addition to definitive airway management, hemodynamic support is among the most important life-saving interventions implemented by emergency physicians. When a patient develops persistent hypotension, what is your approach to choosing the right medication for hemodynamic support? […]

Patwari Academy videos: EBM Treatment Studies

By |Categories: Patwari Videos|Tags: |

Dr. Rahul Patwari reviews evidence-based medicine (EBM) concepts specifically regarding treatment studies, as guided by the JAMA Users Guide to the Medical Literature manual. In these first three videos, Rahul provides a brief introduction to the concept of treatment studies and then discusses (1) how to assess whether the results are valid and (2) calculating the risks/benefits of treatment based on the IST-3 trial? […]

Supraventricular Tachycardia (SVT): Are Troponins Necessary?

By |Categories: Cardiovascular|

More than one third of patients will have chest pain associated with SVT causing providers to order troponins and other cardiac enzymes. Elevated troponins are not pathognomonic for CAD/ACS and could represent other etiologies such as sepsis, subarachnoid hemorrhage, and pulmonary embolism. Also, subsequent coronary angiography is not necessary for risk stratification in all cases. SVT causes a rapid heart rate, which is well documented as a cause for modest troponin elevation secondary to cardiac stretch, poor diastolic perfusion, and/or coronary artery vasospasm. […]

Patwari Academy videos: Spider and Hymenoptera bites

By |Categories: Environmental, Patwari Videos|Tags: |

These two videos continue on the theme of envenomations. Watch these great videos on the consequences and management of bites by spiders and Hymenoptera species (bees, wasps, ants). Hymenoptera bites can cause all sorts of complications, but one of the most worrisome includes anaphylaxis, which is also reviewed in the video. […]

Pediatric febrile seizure: When do I need to do a lumbar puncture?

By |Categories: Neurology, Pediatrics|

You are in the ED when a 7 month old is brought in by EMS after a witnessed generalized seizure. The grandmother reports that the child has had URI symptoms for a couple of days and then developed a fever today. Shortly after giving ibuprofen, the child began to seize with arms and legs twitching. The episode lasted approximately 8 minutes and when EMS arrived, the child was sleepy, but arousable. The glucose was 92 mg/dL en route. On exam in the ED, child is awake and staring at you to make the next move… Vitals: Temp 39C, P 136, [...]

Posterior Myocardial Infarction: How Accurate is the Flipped ECG Trick?

By |Categories: Cardiovascular, ECG|

Posterior myocardial infarction (MI) represents 3.3 – 21% of all acute MIs and can be difficult to diagnose by the standard precordial leads. Typically, leads V7 – V9 are needed to diagnose this entity. Luckily, leads V1 – V3, directly face the posterior wall of the left ventricle and are the “mirror image” of the posterior wall of the left ventricle. […]

Safe dosing of nebulized lidocaine

By |Categories: ENT, Tox & Medications|

Serum lidocaine levels correlate well with observed clinical effects. As the concentration increases, lightheadedness, tremors, hallucinations, seizures, and cardiac arrest can occur. Levels > 5 mcg/mL are associated with serious toxicity. With so many concentrations (1%, 2%, 4%) and routes of administration available, the total dose of lidocaine is always a concern. […]

Trick of the Trade: The PIPP for deep peripheral IVs in obese patients

By |Categories: Tricks of the Trade, Ultrasound|Tags: |

The Case A 500-pound morbidly obese male presents to your ED complaining of mild shortness of breath and palpitations. A quick ECG shows SVT with a rate of 160 bpm. His BP is in the 130s systolic, and he is otherwise stable. You know you have a bit of time. Meanwhile, the nurses begin searching for veins to start an IV…  […]
