Lidocaine + Bupivacaine vs Bupivacaine Alone for Digital Nerve Blocks

Digital Nerve BlocksWhen I first learned digital nerve blocks in the late 1990’s I was taught to mix Lidocaine and Bupivacaine 50/50 to provide faster onset (Lidocaine) and a longer duration of action (Bupivacaine). My use of two agents for digital nerve blocks was recently questioned by one of my colleagues.

Any time additional medications are drawn up into a syringe there is opportunity for error, and there is additional time added to the procedure. A review of the (limited) literature will try to answer the following questions:

  1. Does the addition of Lidocaine to Bupivacaine decrease the time to onset of anesthesia?
  2. Does the addition of Lidocaine to Bupivacaine decrease the pain of injection?
  3. Does the use of Lidocaine with Epinephrine prolong the duration of digital block long enough to obviate the need for Bupivacaine?

April 2015 REBELCastWelcome to the April 2015 REBELCast, where Swami, Matt, and I are going to tackle a couple of articles just published this year. Today we are going to specifically tackle:

  • Topic #1: Basic Life Support (BLS) vs Advanced Cardiac Life Support (ACLS) in Out of Hospital Cardiac Arrest (OHCA)
  • Topic #2: PROMISE Trial – Anatomic vs Functional Testing for Coronary Artery Disease (CAD)

Do Patients with Epistaxis Managed by Nasal Packing Require Prophylactic Antibiotics?

March 30, 2015

EpistaxisEpistaxis is a common Emergency Department (ED) complaint with over 450,000 visits per year and a lifetime incidence of 60% (Gifford 2008, Pallin 2005). Posterior epistaxis is considerably less common than anterior epistaxis and represents about 5-10% of all presentations. Many patients with posterior epistaxis will be managed with a posterior pack and admitted for further monitoring. Traditional teaching argues that:

  1. Patients with nasal packs should be given prophylactic antibiotics to prevent serious infectious complications.
  2. Patients with posterior packs should be admitted to the ICU for cardiac monitoring as they are at risk for serious bradydysrhythmias.

The Protocolised Management in Sepsis (ProMISe) Trial

ProMISeSince 2002, the surviving sepsis campaign (SSC) has stated that best practice in sepsis care includes: early recognition, source control, appropriate/timely antibiotic therapy, resuscitation with intravenous fluids (IVF) and vasoactive medications. Resuscitation of the septic patient in the emergency department has been largely based off the 2001 Rivers trial. This single center study’s focus was to optimize tissue oxygen delivery following several parameters including, central venous pressure (CVP), mean arterial pressure (MAP), and central venous oxygen saturation (SCVO2) to guide IVF, vasoactive medications, and packed red blood cell (PRBC) transfusions. Well today, part 3 of the sepsis trilogy was published in the saga of Early Goal Directed Therapy (EGDT) versus “usual” care. The 3 parts to this saga consist of:

  1. Protocolized Care for Early Septic Shock (ProCESS) – 31 Emergency Departments in the United States
  2. Australasian Resuscitation in Sepsis Evaluation (ARISE) – 51 Emergency Departments in Australia, New Zealand, Finland, Hong Kong, and Ireland
  3. The Protocolised Management in Sepsis (ProMISe) Trial – 56 Emergency Departments in the United Kingdom Read more →

The New Age of Sepsis Management

March 16, 2015

SepsisThere are more than 750,000 cases of severe sepsis and septic shock in the US each year.  Most patients who present with sepsis receive their initial care in the emergency department.  In 2001, there was a landmark study by Rivers et al that reported that among patients with severe sepsis or septic shock mortality was significantly lower among those who received a 6 hour protocol of Early Goal-Directed Therapy (EGDT) (i.e. 30.5% vs 46.5%). The premise of EGDT was that “usual care” lacked aggressive, timely assessment and treatment. The EGDT protocol used central venous catheterization (CVC) to monitor central venous pressure (CVP) and central venous oxygen saturation (SCVO2) to guide the use of intravenous fluids (IVFs), vasopressors, packed red blood cell (PRBC) transfusions, and dobutamine in order to achieve pre-specified physiological targets.  Since the publication of this landmark article, physicians have become more aggressive in the management of sepsis which raises the question of whether all elements of the protocol are still necessary.  Read more →
