When 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?

In the United States, trauma is the leading cause of death among patients between the ages of 1 and 44 years of age and the third leading cause of death overall. Approximately 20 to 40% of trauma deaths occur after hospital admission and are a result of massive hemorrhage.  There have been no large, multi-center, randomized clinical trials with survival as a primary end point that support optimal trauma resuscitation practices with approved blood products and therefore there are many conflicting recommendations. The Prosective Observational Multicenter Major Trauma Transfusion (PROMMT) Trial demonstrated that many clinicians were transfusing patients with blood products in a ratio of 1:1:1 or 1:1:2 and that early transfusion of plasma was associated with improved 6-hour survival after admission. The Pragmatic, Randomized Optimal Platelet and Plasma Ratios (PROPPR) Trial was designed to address the effectiveness and safety of 1:1:1 transfusion ratio vs 1:1:2 in patients with trauma who were predicted to receive a massive transfusion.
