PV card: VBG versus ABG

By |Categories: ALiEM Cards, Endocrine-Metabolic, Pulmonary|

You obtain a venous blood gas (VBG) on a patient with a COPD exacerbation because you are concerned about hypercarbia. You get a value of 55 mmHg. How correlative is that compared to an arterial blood gas (ABG). There has been a lot of literature on how well the pH correlates between the ABG and VBG but what about pCO2? A small study (n=89) from 20121 found that with a cutoff of pCO2 < 45 mmHg, the venous pCO2 is 100% sensitive in ruling out arterial hypercarbia. When the pCO2 was ≥ 45 mmHg, the VBG was less correlative. Below is [+]

PV card: Diagnosis of DVT (ACCP guidelines)

By |Categories: ALiEM Cards, Cardiovascular|

A patient presents with an asymmetric leg with trace pitting edema in the affected leg. What is your diagnostic approach to such a patient? What is the role of D-dimer and ultrasound (U/S)? Does this match the 2012 American College of Chest Physicians (ACCP) guidelines? The first step is to determine your patient's pretest probability because the recommendations vary based on risk. I can tell you that many ED patients come in with a Wells score of 1-2, which places them in the "moderate pretest probability" category. There are 2 approaches you can take based on the availability of resources at [+]

Trick of Trade: Incision and loop drainage using tourniquet

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

The technique for abscess drainage traditionally is incision and drainage (I&D). In August 2012, I wrote about incision and loop drainage (I&LD), which it seems has gained popularity over time with similar outcomes. This technique involves using a sterile vascular loop, which is thin and long enough to form a loose knotted loop. The video below by Dr. Rob Orman reviews the steps. But, what if you don’t have a vascular loop in the ED? [+]

Patwari Academy videos: Low risk chest pain

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

One of the most common complaints in the Emergency Department is chest pain. Is it something serious? How do I risk-stratify patients with potential acute coronary syndrome? What should I be thinking of and not missing? Rahul goes over the low-risk chest pain patient in 2 great, short teaching videos, based partly on the 2010 AHA/ACC Guideline for ACS risk stratification. [+]
