Use of levosimendan in the ICU Levosimendan is an inodilator that promotes cardiac contractility primarily through calcium sensitisation of cardiac troponin C and vasodilatation via opening of adenosine triphosphate-sensitive potassium (KATP) channels in vascular smooth muscle cells. The drug also exerts organ-protective effects through a similar effect on mitochondrial KATP channels. Levosimendan has been demonstrated to have potential utility in a wide range o...

Artificial Intelligence in the ICU The paucity of positive multicentre prospective randomised control trials in ICU settings serves to highlight the challenge of running studies in such environments, where multiple treatments are given simultaneously to individuals who respond in variable ways based on their individual physiology. Consequently, without established guidelines, ICU clinician decision-making is driven largely by experience and instinct, resulting in s...

New algorithm reduces testing for ICU patients Enrolling seriously ill patients in intensive care units for clinical trials is often a big challenge for investigators. This is one reason why there is a dearth of evidence-based guidelines in critical medicine. For instance, ICU doctors often face a dilemma when it comes to ordering lab tests for specific patients.  While ICU doctors are aware that every blood test they order could yield critical informatio...

AKI: long-term impact on mortality and renal function Acute kidney injury (AKI) is defined as an abrupt loss in renal function and may be caused by a wide variety of clinical conditions. AKI is a frequent complication of hospitalisation and is associated with an increased risk of chronic kidney disease (CKD), end-stage renal disease (ESRD), and mortality.Based on more recent studies, AKI is also known to be a risk factor for other adverse outcomes, including stroke...

Editorial|February 17, 2019 How Best to Resuscitate Patients With Septic Shock? Derek C. Angus JAMA. 2019;321(7):647-648. doi:10.1001/jama.2019.0070 What is the best approach for resuscitation of a patient with septic shock? Despite considerable investigation over several decades, this important question still has no clear answer. There is agreement that resuscitation should proceed quickly, for the longer the delay, the greater the physiologic ...

PulmCrit: The surviving sepsis campaign 1-hour bundle is… back? February 12, 2019 by Josh Farkas The surviving sepsis campaign (SSC) has had substantial problems dating back to its inception.  The original backbone of the guidelines was a single-center trial by Rivers, which has largely been debunked.1–4  Initially the SSC was slow to let go of invasive early goal-directed therapy.  The SSC has finally started eliminating older dogma (e.g., ...
