From Oct 6th – 8th, 2020, Haney Mallemat (@CriticalCareNow) and his team put on an absolutely amazing online critical care conference called ResusX Rewired.  ResusX is a conference designed by resuscitationists to provide clinicians with the most up to date skills and knowledge to help make a difference in your patients' lives.  Haney and his crew made a combination of short-format, high-yield lectures, and completely customizable small group sessions with procedural demos seem easy.  There were so many high-quality speakers and pearls that I learned from this conference that I wanted to archive them here in one post for reference and to share with our readers/followers.

Background Information:

It is well documented throughout the literature that critically ill patients admitted to the intensive care unit (ICU) with acute kidney injury have a higher morbidity and mortality.1–4 Acute kidney injury may be complicated by acidosis, hyperkalemia and other major metabolic disorders and thus the initiation of renal replacement therapy (RRT) is generally considered beneficial in these patients.5 In patients without these complications, the timing of when to initiate RRT remains unclear and is frequently debated. There are three trials to know before getting to this one: ELAIN, IDEAL and AKIKI. The ELAIN trial was the only one of the three to show reduced 90-day mortality with early vs delayed initiation of RRT and was the smallest in sample size.6 The IDEAL trial concluded that early planned initiation of dialysis in stage V chronic kidney disease was not associated with improvement in survival or clinical outcomes.7 Lastly, the AKIKI trial found no significant difference with regard to mortality between an early and delayed strategy of RRT and actually saw an appreciable number of patients avert the need for RRT in a delayed strategy.8 The authors of the following study sought to investigate whether an accelerated strategy for RRT would result in lower risk of death from any cause at 90 days when compared to a standard strategy of RRT initiation.

Background: In end-stage renal disease (ESRD) patients on hemodialysis (HD), infection is the second most common cause of mortality after cardiovascular disease (Sarnik 2000). Because of the systemic inflammation and increased capillary permeability, septic patients are at significant risk for fluid imbalances and frequently require large volumes of crystalloids. The Surviving Sepsis Campaign guidelines provide a strong recommendation with low quality of evidence for administering a 30mL/kg fluid bolus within 3 hours of recognition of sepsis-induced hypoperfusion (Rhodes 2016). Further fluid administration should be guided by hemodynamic assessment (bedside echocardiography, passive leg-raise, etc.). In the general population, this early administration of fluids to patients with hypotension or sepsis-induced hypoperfusion has been associated with improved outcomes. However, there is significant confusion regarding the effects of a large 30mL/kg bolus on ESRD patients due to a lack of studies. While these patients may appear, volume overloaded on physical exam, they may be intravascularly volume deplete. Physicians may be hesitant to administer a large fluid bolus in ESRD patients because of the risk of precipitating cardiogenic shock, pulmonary edema, and respiratory failure. In fact, multiple studies show that patients who have ESRD are less likely to receive the full 30mL/kg fluid bolus compared to non-ESRD patients (Lowe 2018, Truong 2019, Dagher 2015). Furthermore, some studies show equivalent outcomes between ESRD patients who receive the full bolus and those who do not. We will review two studies that examined this topic.

Take Home Points
  1. Hyperthyroidism can present along a spectrum from the minimally symptomatic to severely decompensated and presentation can vary with age
  2. If there are a lot of interconnecting systems complaints consider obtaibning a TSH, t3 and t4 
  3. Once you’ve diagnosed hyperthyroidism, dont anchor on it. Look for what might have caused it especially in those with comorbidities
  4. If the patient is stable and reliable you can discharge them home with Atenolol. Make sure to have the patient follow up with their PCP or Endocrinologist. If, however, you feel uncomfortable doing that or the patient needs more social support, call your endocrinologist on call and get their recommendations.

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.
