Take Home Points

  • When compared to 0.9% saline, lactated ringers is a more balanced solution and more closely resembles our serum.
  • SALT ED and SMART trials show normal saline may increase the occurrence of major adverse kidney events in comparison to a balanced solution like LR. For large volume resuscitations, LR is a better choice.
  • Certain medications cannot be run with LR in the same IV line. Ampicillin, Carbapenems, Phenytoin, Potassium Phosphate, Nicardipine
  • Ceftriaxone and LR should never be running at the same time in children less than 28 days old.

Background: The combination of vitamin C, hydrocortisone and thiamine in sepsis has been a topic of hot debate in the past couple years.  There is a hypothetical pathophysiological basis to make an argument for the use of this combination of medications, but as with anything it is important to ensure there are no untoward effects either. In Dr. Marik’s before and after study [1] we saw some pretty amazing results showing that treatment reduced hospital mortality  by 31.9% (Treatment Group 8.5% vs Control Group 40.4%). Too good to be true?  Well in short, YES…the major issues with this study were it was not a randomized controlled trial, had a small sample size, was a single center study, and had significant selection bias.  Well we finally have our first randomized controlled trial evaluating the “metabolic cocktail” in a general population of septic shock adult patients.

Therapeutic Hypothermia (also called targeted temperature management (TTM)) is a deliberate reduction of the core body temperature to 32 - 34°C, in patients who suffer cardiac arrest with return of spontaneous circulation, but also don't regain consciousness.  In REBEL Crit Cast episode 1, I will go through the evidence for cooling adults and children, potential adverse effects, and what temperature to shoot for.

Background: Traditionally, vasopressors have been given through central venous catheters (CVCs) in the critically ill.However, the time it takes to place a CVC is time a patient could potentially remain hypotensive. Early initiation of vasopressors may be associated with reduced mortality by increasing end-organ perfusion. Therefore, there has been a growing trend to use vasopressors through peripheral IVs (PIVs).  Running pressors through a peripheral IV has a couple of important benefits including faster time to pressor initiation and no need for invasive procedures (i.e. CVC). There islittle evidence to support the safety of this practice other than one systematic review which included case reports and small case series. Now we have two more papers that evaluate this very question…are peripheral pressors safe?

You are working at a Level 1 Trauma Center; a 35-year-old female arrives via EMS from the scene of a motor vehicle accident. She was an unrestrained passenger, ejected 50 feet. She was hypotensive and hypoxic on scene with concern for head injury with a GCS of 7. She is clearly in shock on arrival with weak pulses, clammy skin, and a BP of 80/50mmHg, HR 140, sats 85%.  She is intubated, a chest tube is placed on the left (with improvement in O2 sats to 95%), and a pelvic binder is placed for suspected pelvic fracture. eFast demonstrates free fluid in the pelvis. Massive Transfusion Protocol (MTP) has been activated appropriately, and despite rapid delivery of 4 units Packed Red Blood Cells (PRBCs), 2 units of Fresh Frozen Plasma (FFP) and 1 pack of Platelets, she remains hypotensive, with presumed hemorrhagic shock. The patient is destined for the OR, but you ask yourself, in traumatic hemorrhagic shock, is there a role for vasoactive agents?
