Albumin in Cirrhosis
RCT
In 777 patients, albumin infusions to increase the albumin level to a target of 30 g per liter or more did not improve the composite primary outcome of new infection, kidney dysfunction, or death between days 3 and 15, but resulted in increased adverse events

Hepatorenal Syndrome
RCT
In 300 adults with cirrhosis and HRS-1, terlipressin was more effective in improving renal function but resulted in less liver transplantation (23% vs 29%) a higher 90-day mortality (51% vs 45%).

Recovery of Consciousness
Observational Study
In 17,470 patients in the Traumatic Brain Injury Model Systems National Database, 7,547 (57%) suffered an initial loss of consciousness, which persisted to rehabilitation in 2,058 patients (12%). Of this group of 2,058 comatose patients, 82% (n = 1674) subsequently recovered consciousness during inpatient rehabilitation.

Convalescent Plasma
Meta Analyses
In a systematic review of 4 published trials including 1060 patients with confirmed or treated COVID-19 in any treatment setting, the use of convalescent plasma was not associated with a significant reduction in all-cause mortality; risk ration 0.93 (95% CI, 0.63 to 1.38).

RECOVERY - Dexamethasone arm
RCT
Originally published in provisional format last Summer, the full paper of the RECOVERY trial - dexamethasone arm, is now out. In 6425 hospitalised patients with COVID-19, treatment with 10 mg IV dexamethasone for up to 10 days resulted in a lower 28-day mortality among those who were receiving either invasive mechanical ventilation or oxygen alone.

The BACLOREA Trial
RCT
The BACLOREA trial, initial presented at eCCR21, reported a decrease in agitation-related events with baclofen in 314 mechanically ventilated patients with alcohol misuse disorder (19.7% vs. 29.7% with placebo), but a longer length of mechanical ventilation (9 vs 8 days) and stay in the ICU (14 vs 11 days.

The VICTAS Trial
RCT
The VICTAS trial, comparing treatment with vitamin C, thiamine, and hydrocortisone with placebo in 501 patients with septic shock, reported no significant difference in ventilator- and vasopressor-free days (25 vs 26 , respectively) at 30 days. Funding was withdrawn after just 501 out of a planned 2000 patients were recruited.

Anticoagulation in COVID-19
The ACTIV4-a, ATTACC, & REMAP-CAP investigators will present the results of this multi-platform trial examining therapeutic & prophylactic anti- coagulation in patients with COVID-19. The interim analysis was released January 28th and is available via the link below.
TTM post Cardiac Arrest
Originally planned for CCR21, which became eCCR21, but delayed into the Spring, the long awaited results of the follow-up trial to the landmark targeted temperature management after out-of-hospital cardiac arrest is out soon. Is the avoidance of fever the critical aspect of TTM? The results are due very soon.
Balanced IV Fluid Solutions
This massive 11,000 patient trial from Brazil was also scheduled for CCR21, but was unavoidably delayed due to the pandemic. Comparing Plasma-Lyte 148 with 0.9% saline, it's almost ready for release now and we're delighted to be hosting this major trial result later this Spring.
Latest Major RCTs
Vitamin D for COVID-19
In a Brazilian two-centre, blinded RCT in 240 patients with moderate or severe COVID-19, Murai and colleagues reported that a single oral dose of 200 000 IU vitamin D3 did not significantly change the median (IQR) length of hospitalisation; vitamin D3 group, 7.0 (4.0-10.0) days, vs. placebo group, 7.0 (5.0-13.0) days; log-rank, P = 0.59; unadjusted HR, 1.07; 95% CI, 0.82-1.39; P = 0.62.

REALITY Trial
In 668 patients with acute myocardial infarction and a hemoglobin level between 7 and 10 g/dL, a red cell transfusion threshold of ≤8 g/dL was found to be non-inferior to a threshold of ≤10 g/dL, with the composite MACE outcome (all-cause death, stroke, recurrent myocardial infarction, or emergency revascularization) at 30 days occurring in 11% vs 14%, respectively.
Fluids After Bypass Study
In 715 patients undergoing cardiopulmonary bypass and randomised to a protocol-guided strategy, using stroke volume variation to guide the administration of bolus fluids, or to usual care fluid administration, until desedation or up to 24 hours, there was no difference in the primary outcome of ICU length of stay; (median/IQR) intervention group; 27.9 hr (21.8–53.5 hr) vs control, 25.6 hr (21.9–64.6 hr); p = 0.95.

MENDS2 Trial
In 432 ventilated adults with sepsis, randomised to receive IV sedation with either dexmedetomidine (0.2 to 1.5 μg/kg/hr) or propofol (5 to 50 μg/kg/min), there was no difference between groups in the primary outcome of days alive without delirium or coma during the 14-day intervention period; 10.7 vs. 10.8 days; OR, 0.96; 95% CI, 0.74 to 1.26; respectively. There were also no differences in secondary outcomes, including mortality.

Hypothermia for TBI with refractory intracranial hypertension
In adult patients suffering a traumatic brain injury, with a GCS score of 4 to 8, and initial ICP ≥ 25 mm Hg, the implementation of long-term mild hypothermia group (34–35 °C for 5 days), in comparison with normothermia group at 37 °C, did not improve the proportion with a favorable outcome (OR 1·55, 95%CI 0·91–2·64; P = 0·105) or mortality (P = 0·111) at 6 months.

Resumption of Cardiac Activity after Withdrawal of Life-Sustaining Measures
In a prospective study in 20 ICUs in 3 countries, amongst 631 patients who underwent continued monitoring after planned withdrawal of life-sustaining support, 14% of patients had a resumption of cardiac activity after a period of pulselessness. Just 1 percent were observed clinically. The longest period to resumption of cardaic activity was 4 minutes 20 seconds.

HOT-ICU Trial Results
In a Danish led, international, multi-centre, randomised controlled trial trial in 2928 adults with acute hypoxaemic respiratory failure, targetting a PaO2 of 8 kPa, in comparison with 12 kPa, did not improve the primary outcome of 90-day mortality (42.9% vs 42.4%; adjusted risk ratio, 1.02; 95% CI, 0.94 to 1.11; P=0.64).

Tocilizumab in patients with severe or critical COVID-19
In a Brazilian randomised controlled trial involving 9 hospitals, the use of tocilizumab as a single intravenous infusion of 8 mg/kg plus standard care (n=65) versus standard care alone (n=64), resulted in suimilar levels of mechanical ventilation at day 15 (28% vs. 20; (odds ratio 1.54, 95% CI0.66 to 3.66; P=0.32).), respectively, and increased mortality (17% vs. 3%; odds ratio 6.42, 95% CI,1.59 to 43.2).

Tocilizumab & sarilumab reduce mortality in severe COVID-19
In a pre-print paper, the REMAP-CAP trial investigators have reported efficacy with interleukin 6 receptor anatgonists in critically ill patients with COVID-19. Hospital mortality was 28.0% (98/350) for tocilizumab, 22.2% (10/45) for sarilumab and 35.8% (142/397) for control.

Three large randomised controlled trials, ATTACC, @ACTIV4a, and REMAP-CAP, have, for futility, halted recruitment to their therapeutic anticoagulation arms in critically ill patients with COVID-19.
Other Recent RCTS of Note
Inhaled Heparin for ARDS
In this multi-centre, blinded Australian trial, 25 000 IU of nebulised heparin administered 6 hourly while invasively ventilated, did not significantly alter the primary outcome of functional outcomes (SF-36) at 60 days; survivors in the heparin group (n=97) mean 53·6 vs control 48·7; difference 4·9 [95% CI –4·8 to 14·5]; p=0·32).
Procalcitonin to Reduce Long-Term Infection-associated Adverse Events in Sepsis
In this trial PCT-guided antimicrobial treatment in sepsis was effective in reducing infection-associated adverse events like infections by multidrug-resistant organisms and Clostridioides difficile, as well as in-hospital and 28-day mortality.
