Listen

Today in clinic a Dene Elder says to me while I am listening to his heart, "If it sounds a little different, it's 'cuz it has a Native beat".

I have never laughed so hard with a stethoscope in my ears.

One of those patients that I felt an instant connection with. I stared at those deep laugh lines etched in his tan skin while he told me about his cardiology appointment. He pulled out a palm sized moleskin notebook and recited ejection fractions and names of specialists and amiodarone adjustments (which he doesn't care for, after all the reading up he's done on it). He told me that when he had his heart attack he remembered being wheeled in through the hospital doors and that when they closed behind him, many other areas of his life closed behind him too. He woke up eight days later in a cardiac intensive care unit.

He golfs, he lifts weights, he walks everyday. His intensivist told him he was a "ticking time bomb" but he pointed out to me that he was still here. I told him I was glad of that.

I wanted to cancel the rest of my afternoon and just listen. Such a vivid cast of characters in this unfolding narrative which is my life.

With the Scientific Endorsement of SEEIUC

Hola a tod@s, my dear friends:

Today is one of those days in which one has the satisfaction and honour to share good news with friends.

I am sharing the letter that I received yesterday from the President of the Spanish Society of Intensive Nursing and Coronary Units (SEEIUC), Rosa Jam:




This is a great reason to continue giving our best,  and that all you continue feeling as part of IC-HU Project.
Every day, Nurses and physicians working in the same awesome team as what we are, the professionals of the critical ill patient.

I will pay this round of beers!!.

Health and congrats for everybody!

Laursen CB, et al. Point-of-care ultrasonography in patients admitted with respiratory symptoms: a single-blind, randomized controlled trial. The Lancet Respiratory Medicine – July 2014 PMID: 24998674

  • One of the first RCTs examining the utility of POCUS for ED patients presenting with dyspnea. Using a POCUS protocol performed by a single experienced provider, examining the heart, lungs, and deep veins of the LE, authors found significant improvement in their primary endpoint – the rate of correct diagnoses made at 4 hours. Though promising, these benefits did not translate into improvements in hospital or 30 day mortality, length of stay or hospital free days. Furthermore there was a significant increase in downstream testing in patients randomized to the POCUS group indicating there may be a degree of over-diagnosis that occurs with the introduction of such a protocol. (Rory Spiegel)
  • This is further evidence that POCUS of the chest may be of benefit in the ED. However, although this is an RCT there are some significant biases within it. Whilst I personally agree with the results and in all honesty I wish them to be true, there is not evidence here to firmly change practice. For me I would like to see more studies using a broader population base, multiple USS operators and larger numbers. (Simon Carley)

Righini M et al.Age-adjusted D-dimer cutoff levels to rule out pulmonary embolism: the ADJUST-PE study.JAMA. 2014 Mar 19;311(11):1117-24. PubMed PMID: 24643601. [JAMA Full Text]

  • This study prospectively validated whether an age-adjusted D-dimer cutoff was associated with an increased diagnostic yield of D-dimer in elderly patients with suspected PE. Compared with a fixed D-dimer cutoff, the combination of pretest clinical probability assessment with age-adjusted D-dimer cutoff was associated with a larger number of patients in whom PE could be considered ruled out with a low likelihood of subsequent clinical venous thromboembolism. So if this is not your clinical practice already, maybe time to use age adjust d-dimer values?

Harvey V, Perrone J, Kim P.Does the Use of Tranexamic Acid Improve Trauma Mortality? Ann Emerg Med 2014; 63(4):460-462. PMID 24095056 [Annals Full Text]

  • This is a review of the literature regarding tranexamic acid use in traumatic hemorrhage showing that tranexamic acid significantly decrease mortality in bleeding trauma patients, without significantly increasing serious prothrombotic complications if administered within 3 hours of injury. There is, however, no evidence of benefit in patients with traumatic brain injury. The authors recommend early treatment with tranexamic acid in trauma patients without isolated brain injuries who have or are at risk for significant hemorrhage and in patients who receive resuscitation with blood products, particularly if they require massive transfusion or have a high risk of death at baseline.

Kelleher DC et al.Factors affecting team size and task performance in pediatric trauma resuscitation. Pediatr Emerg Care. 2014 Apr;30(4):248-53. PMID 24651216

  • This study investigates factors associated with varying team size and task completion during trauma resuscitation. Video of 201 pediatric trauma resuscitations were reviewed and task completion was then analyzed in relation to team size using best-fit curves. Having 7 people at the bedside during a pediatric trauma resuscitation was optimal in patient management. Beyond this number, the investigators saw diminishing returns.

Allon M et al.Effect of bicarbonate administration on plasma potassium in dialysis patients: interactions with insulin and albuterol. Am J Kidney Dis. 1996 Oct;28(4):508-14. PMID: 8840939 [AJKD Full Text]

  • This is the paper that should have pushed people away from using bicarb in hyperkalemia, or at least started them towards researching it. Whereas insulin and albuterol are effective temporizing measures to shift potassium rapidly from the extracellular to the intracellular fluid compartments and thereby lowering plasma potassium acutely, bicarbonate by itself is not. But bicarbonate is believed to have a potentiating effect on albuterol and insulin. Using a prospective cross-over design, 6 treatment protocols combining bicarbonate, albuterol, insulin and saline respectively were investigated for acute effects on plasma potassium as well as blood bicarbonate and pH in nondiabetic hemodialysis patients. The resulst observations suggest that bicarbonate administration does not potentiate the potassium-lowering effects of insulin or albuterol in this patient population.

  • Heriditary bleeding disorders are reletively rare and most often are treated in out-patients-clinics. Emergency physicians rarely encounter them with the potiential for delays in diagnosis and administration of replacement therapy. In this great review of ED evaluation and management of hemophilia and Von Willebrand disease to outline some of the issues facing emergency physicians and the options available for the treatment of these patients.

Hwang V et al.Prevalence of traumatic injuries in drowning and near drowning in children and adolescents. Arch Pediatr Adolesc Med. 2003 Jan;157(1):50-3. PMID: 12517194 [JAMA Full text]

  • In this ten-year retrospective review of pediatric drowning and near drowning the prevalence of traumatic injury was low. In fact the authors only identified cervical spine injuries, and all but 1 patient had a clear history of diving. Use of specialized trauma evaluations may not be warranted for patients in drowning and near-drowning accidents without a clear history of traumatic mechanism. So not all submersion victims are trauma victims! If they are not a trauma victim, then do you and the patient a favor and remove the C-Collar.

  • Preinjury use of antiplatelet agents (i.e. aspirin, clopidogrel) is common. Patients with ICH on these agents have higher morbidity and mortality. this systematic review reveals the lack of evidence to support or refute the utility of platelet transfusion in these patients. Physicians must weight the risks and benefits of a platelet transfusion in patients on antiplatelet agents who present with traumatic ICH.

Shokoohi H et al.Ultrasound-guided peripheral intravenous access program is associated with a marked reduction in central venous catheter use in noncritically ill emergency department patients. Ann Emerg Med. 2013 Feb;61(2):198-203. PMID 23141920 [Annals Full Text]

  • A well-instituted US-guided peripheral IV program will indeed decrease rates of central line insertion. Among of 401,532 patients, 1,583 (0.39%) received a central venous catheter. During a 5-year study period the rate of central line placement decreased by 80% The decrease in the rate was significantly greater among non-critically ill patients than critically ill patients. Not groundbreaking but nice to have some solid evidence.

Philips VISIQ Tablet Ultrasound Now Cleared in U.S. (VIDEO)

VISIQ ultrasound Philips VISIQ Tablet Ultrasound Now Cleared in U.S. (VIDEO)
Philips received FDA clearance for its VISIQ ultrasound, a device that looks, and in many ways acts, like an iPad with an attached transducer. It’s intended to be used for abdominal and obstetric imaging procedures, coming with a single transducer that features a broadband micro-digital beam former and image acquisition module. Philips claims the VISIQ produces image quality comparable to cart-based systems.

It’s controlled using the touchscreen, utilizing many of the same gestures now commonly used in consumer devices. The device includes powerful capabilities such as image measurement and image optimization. It has built-in Wi-Fi, allowing it to dump its data to a PACS system for later review on other workstations.

The device is already CE marked in Europe and is available in select countries around the world.
